1. How can I modify the size of swap with LVM partitions?

I do not like using GParted, partially because most of my servers are without GUI.Here's how to extend a swap setup as a logical volume:1) Determine the name of the swap logical volume using the "lvs" command:2) Turn off the swap partition:3) Resize the swap partition, adding 15GB more space to it:4) Format the new swap space to make it usable:5) Turn the swap volume back on:6) Use free command to show your new swap space:

2. Stop volumes/partitions from auto-mounting

To keep the filesystem from being mounted automatically, you may add a line to your /etc/fstab file, using e.g. sudo nano /etc/fstab or whatever editor you prefer. The line should readwhere /some-path means the directory where the filesystem should be mounted. This must exist and be writeable by you. Option noautosays the filesystem will not be mounted automatically, and user says that normal users are allowed to mount the filesystem

5. how to partition hard drive.?

Kind of confused in what you are trying to achieve. If you simply want to create a new partition download 'Partition Magic.' Comes with features to create partitions as well as installing new os' on sed hard drive. Edit: Read what you want to do. Pretty sure all you need to do is download Partition Magic, its simple to use and pretty self-explanatory to make new partitions. I apologise if you already know this and I am sounding like and idiot Double Edit: Sorry, its called Partition Magic. And I would suggest using this as if you try and edit things yourself you could end up damaging files etc. and digging yourself into a hole.

6. Distance between two partitions of a set

Try this: Call the partition with the largest number of parts $P_1$, the first partition (if it's a tie, pick whichever)Arbitrarily label the parts in $P_1$.Starting with a largest part $p$ of the second partition $P_2$, find a part $p'$ of $P_1$ so that $p cap p'$ is as large as possible (if there is a tie, break it however). Label $p$ with the same label as $p'$Repeat the preceding step until all of the parts in the second partition are labeled, never reusing labels within $P_2$.This wo not in general be unique.For example: $$ textPartition 1: underbrace1,2_A,underbrace3_B,underbrace4,5,6_C qquad textPartition 2: underbrace1,2,3_A,underbrace4,5,6_C $$Then, you can think of each partition as a bunch of orderd pairs:$P_1 = (1, A), (2, A), (3, B), (4, C), (5, C), (6, C)$ for the first, and$P_2 = (1, A), (2, A), (3, A), (4, C), (5, C), (6, C)$ for the second.Viewing these partitions as the set of ordered pairs, then the $1$ just so happens to be $|P| - |P_1 setminus P_2| = n - |P_1 setminus P_2|$; $n$ minus the number of things belonging to sets with the same label. In general, I believe $n - |P_1 setminus P_2|$ should count the number of differences, as you've described it. I've tried to think of a pair of partitions for which this technique wo not work, but have not been able to.Disclaimers:

Partitions in the Home
Partitions in the Home
There are many wonderful ways to change and improve the look of your home or office building. Some of these things require very little effort and others will take a great deal of time and effort. Each thing has a purpose and is important in its own way. Some people paint the walls, some put up wallpaper, others buy new furniture, and some redecorate. Then, you have the extreme home improvements that involve changing the entire layout of an area. For some people, this involves taking out a partition, putting in a new partition, or replacing an existing partition. A partition can serve many purposes including creating an entirely new space, separating an area to create two rooms, creating a privacy area, and sheer decorative purposes. Sometimes it is necessary to create new spaces, but there are also times when you want to expand a given area and that requires removing any existing partitions in the way. There is also the option of repainting or replacing a partition. Here, you will learn a wide variety of ways to utilize and change a partition to give your home a whole new look. The first question that has to be asked is you are removing, replacing, or adding a partition in your home. Each of these things will require entirely different information. To start with, here is information about improving your existing partitions. If you have a partition and do not want to remove it, but also do not want to leave it as is, you have two choices. Your first option is to redecorate and improve the partition. The second option is to replace the partition with a different material. The second option is not often advised but is occasionally done. For example, a wooden partition may be replaced with glass wall partitions or vise versa. If you choose to go this route, strongly consider hiring a professional to handle the project. This is not something that you want to mess up if it is at all avoidable. If you want a new look without actually replacing the partition, consider redecorating. This can include paint, wallpaper, decorations, and many other options. You can also add paneling if that is of interest to you. One of the most versatile options is paint. You can use multiple colors, stencils, and any artistic skill to create an amazing look. Some people like to put their favorite quotes on the wall or use stencils and other tools to create a piece of art that represents a fandom or other interest, The possibilities are endless if you dig into your creativity.If you have a partition that you need to remove, the first thing you need to do is ensure that it is indeed nothing more than a partition and is not in any way load bearing. If you have experience with construction, feel free to take this project on yourself, but if you are not comfortable handling tools and working with your hands, it is best to hire a professional. So long as the partition is not load bearing, removing it is actually quite simple. The hardest part is cleaning up the mess created by the removal.If you want to install a partition where that previously was not one, it is almost always best to hire a professional. The exception is if you are very familiar with construction and have worked on similar projects before. Barring these few exceptions, always hire a professional. You want your partition to look amazing which means this is not the time to practice your construction skills. One other exception would be if you were installing a foldable partition that is not a permanent fixture.At this point, you will know whether or not you need to hire a professional. If the answer is yes, here are some tips to help you through this process. The first thing you need to do is compile a list of local professionals that are available for hire. Depending on where you live, there may be multiple companies and a handful of freelancers or there may only be one company. For very rural areas, you may need to check in neighboring towns to find even one professional. The best way to find this information is to head to your favorite search engine and look for the information. The internet is a fantastic place that compiles information for a myriad of places and places it all in one place. Keep the search simple, especial to start with. If your first search does not give you the desired results, alter the search a bit and try again. To get the best results, to begin with, be sure to add the type of professional you are looking for a location descriptor.Next, you will need to make a few decisions to help you narrow down the possibilities. There are many things to consider and each person will have their own unique list of requirements. Some of the most common requirements involve price, experience, and proximity. Most people have a strict budget that they must stick to for any home improvement project. Because of this, it is vital to set a budget before doing anything else. Set your preferred price range as well as the maximum amount you are willing to spend. Next, decide how far away you are willing to look for a professional to hire. Many people prefer to look for professionals that are close to their location while others feel it is irrelevant.After deciding what you need in regards to the professional you hire, you will need to sort through the options and compare each choice to your requirements. After this, if you have still not made a decision, it is time to turn to reviews. These can come from family members, friends, co-workers, acquaintances, or online listings. There are many places online where people can leave reviews for local businesses that they have interacted in any way with. This includes dedicated websites, blogs, social media, and more.

Design Scheme of Multi-channel Voltage Measurement Based on Stm32
Design Scheme of Multi-channel Voltage Measurement Based on Stm32
This design proposes a design scheme of multi-channel voltage measurement based on STM32 chip, and the measurement range is between 0-10V. The built-in A / D of STM32 samples the multi-channel voltage values to obtain the corresponding digital quantity. Then the corresponding analog voltage value is obtained according to the proportional relationship between digital quantity and analog quantity, which is displayed by TFTLCD display equipment, and the multi-channel collected data is stored in SD card.1. IntroductionIn recent years, data acquisition and its application have attracted more and more attention, and data acquisition system has developed rapidly. It can be widely used in various fields.Data acquisition technology is one of the important branches of information science. Data acquisition is also a process of obtaining object information from one or more signals. Data acquisition is an important link in industrial control systems. It is usually realized by some single chip microcomputer systems with relatively independent functions. As an indispensable part of the measurement and control system, the performance characteristics of data acquisition directly affect the whole system.Voltage measurement is the most universal. It is of great significance to study and design methods and instruments to improve voltage measurement accuracy. In the design of voltage measurement, single chip microcomputer as controller is the core of the whole design. In addition, there must be an analog-to-digital converter (ADC) in the design. ADC is used to directly collect analog voltage and convert analog signal into digital signal. It directly affects the accuracy and speed of data acquisition.2. System overviewThe microcontroller of this design adopts STM32 single chip microcomputer.STM32 Series MCU is designed based on the Cortex-M3 core of arm company. Its clock frequency reaches 72mhz. It is a high-performance product among similar products. It has the advantages of high performance, low cost and low power consumption. It is a good choice in embedded application design. The A / D converter in the design adopts STM32 built-in ADC. STM32 ADC is a 12 bit successive approximation analog-to-digital converter.It has up to 18 channels and can measure 16 external and 2 internal signal sources. The A / D conversion of each channel can be performed in single, continuous, scanning or intermittent mode. The conversion results can be stored in the 16 bit data register in left or right alignment. The maximum input clock can reach 14mhzThis design can measure the voltage value of 8 channels, the measurement range is 0-10V, and the display error is ± 0.001V. LCD displays the voltage value and waveform in real time, and microSD card synchronously stores the data. The system principle block diagram is shown in Figure 1.Design scheme of multi-channel voltage measurement based on stm323.3 LCD control circuitThe LCD used in this design is 2.4 inches, 320 & times; 240 resolution. The LCD module is controlled by the FSMC interface of STM32.FSMC (flexible static memory controller) can be changed into static storage controller. It is a unique storage control mechanism of STM32 series high storage density microcontroller with internal integration of flash of more than 256Kb and suffixes Xc, XD and Xe. By setting the special function register, FSMC can send corresponding data / address / control signal types according to different external memory types to match the speed of the signal, so that STM32 series microcontrollers can not only apply various external static memories of different types and speeds, Moreover, it can expand a variety of different types of static memory without adding external devices, so as to meet the comprehensive requirements of system design for storage capacity, product volume and cost.In STM32, one end of FSMC is connected to core Cortex-M3 through internal high-speed bus AHB, and the other end is an external bus for extended memory. After the access signal of the kernel to the external memory is sent to the AHB bus, it is converted into a signal conforming to the communication protocol of the external memory through the FSMC and sent to the corresponding pin of the external memory to realize the data interaction between the kernel and the external memory. FSMC acts as a bridge, which can not only convert the signal type, but also adjust the signal width and timing, so as to shield the differences of different storage types and make them no difference to the kernel.FSMC can connect devices such as nor / PSRAM / NAND / PC card, and has FSMC_ A [25:0] has 26 address buses and FSMC [15:0] has 16 data buses. In addition, the extended storage space of FSMC is divided into 8 blocks. Select the block of the operation through the address line. In this way, the LCD will operate as a memory with one address space.3.4 SD card drive circuitThe SD card used in this design is microSD, also known as TF card. MicroSD card is a very small flash memory card, which is mainly used in mobile phones. However, due to its small volume and the continuous improvement of storage capacity, it has been used in GPS devices, portable music players, digital cameras and some flash memory disks. The pin diagram of microSD card is shown in Figure 9.MicroSD card, like SD card, has SPI and SDIO operation buses. Compared with SDIO bus, SPI bus has simple interface, but its speed is slow. We use SDIO mode.MicroSD card has 4 data lines in SDIO mode.In fact, microSD has 1-wire mode and 4-wire mode in SDIO mode, that is, 1 or 4 data lines are used respectively. Of course, the speed of 4-wire mode is faster than that of 1-wire mode, but the operation is more complex. The 4-wire mode of SDIO is used in this design. The hardware connection diagram of microSD card is shown in Figure 3.STM32 MCU Chinese official websiteSTMicroelectronics / St / STM
How Does Temperature Affect the Speed of Sound?
How Does Temperature Affect the Speed of Sound?
As other answers show, the speed of sound is slightly influenced by temperature.Much more interesting is the influence of gradients in temperature! The usual distribution of temperature at different heights is: high at ground level, decreasing upwards. This profile, with slightly higher sound velocity at ground level causes wave fronts to curve upwards. Sometimes the temperature profile is inverse, from ground level to a certain height, in the order of hundreds of meters. This inversion layer acts as a reflector, causing sound to propagate over much larger distances.It is not the speed as such, but the differences in speed that have important influence on sound propagation.1. How to increase my running speed?No, leaping prime does now not make you a quicker runner. Speed is muscular so you will do whole frame paintings along side plyometrics, which can be exceptional varieties of bounding and leaping to construct explosive force. To get greater at going for walks you ought to run. If you are employed on lifting and doing the plyometrics you are going to have the groundwork to upgrade your going for walks. What form of going for walks are you running for? If it's soccer then you definitely will have to coach for brief bursts of velocity. If it's one other game you have got to appear on the distances required on your game. A huge aspect of velocity it response. That manner the begin. Whether it's out of the blocks in a race, or attending to a fly ball within the outfield. Speed is vigor so that you ought to be ready to loosen up rise up tall, maintain your elbows at ninety levels, swing them directly entrance to again, and now not throughout your frame. Land at the balls of your ft.2. Water flows through a 1.5 cm diameter pipe into a 275 liter bathtub, which it fills in 5 minutes. What is the speed of the water in the pipe?Mass of 275 litres of Water divided by 5 minutes x 60 seconds = Time of 300 secondsMass Flow Rate of 0.9166 litres per secondThis is excessive amount of water in Speed or Velocity to fill a bathtub in 300 seconds. See IPHE & CIBSE CoP & Technical Guidance on maximum flow rate for 15 mm smooth wall copper pipework. The water pressure is another factor is consider.Water flows through a 1.5 cm diameter pipe into a 275 liter bathtub, which it fills in 5 minutes. What is the speed of the water in the pipe?.3. Not getting the download speed I should be getting?you download a file to what ? a phone or a computer? ethernet or wirelessly ? you need to be more clear on how to ask a question, even with my godlike powers i cant read your mind4. Need help gaining speed/trimming fat?challenging task. browse in google. that will may help!5. Why are people so insistent that speed of light is constant for all observers and is the maximum traveling speed?In special relativity, when the speed of light is constant for everyone, time can be different. When different travellers or observers have light remain constant, their time can change to allow for this. So try to wrap your head around the fact that different observers can have differences in time, and this allows the speed of light to remain constant for all observers.6. fur nice fan motor Polly have to be smaller to make the fan go faster?Motor pulley larger or driven pulley smaller will increase speed7. What are the technical factors in a processor that determine its speed?Clock Speed of the Processor and its primary cache size determines its speed in terms of throughput8. Is faster than the speed of light possible?well ist just a theory so it could be or couldnt be true.....einstien said if we could go the speed of light then we cold time travel...other people say it is still expanding....what i want to know is how can all of that crap fit into somthing the size of a pin head lol.9. How to train for faster picking speed on guitar?Assuming we are talking about alternate picking, there are basically two exercise methods for building speed.The first and the better known one is to start slow. Set your metronome to a comfortable tempo and play the exercise a few times. Then go up 2 bpms or so and repeat. Continue alternating between plus two and minus one. Back down some 10 bpm when you hit your limit and work your way up from there again. You can go up 10 bpm or so from time to time just to see how it feels. The second one is to practice in bursts. Start with two notes and play as fast as you can. Then add the third and continue from there. This method is not as well known as the first one but is every bit as useful. You can also start from the most difficult spot on the exercise and add notes on both sides.Practicing scales only is probably not the best way to go. There are specially crafted exercise sets to build speed that isolate common patterns. Troy Stetina's book Speed Mechanics contains one such set.In terms of technique, on your left hand, only apply enough pressure to avoid buzz. You will get tired very quickly if you exert more force than necessary. The lighter your left hand touch is, the easier it is to play fast. It's easier said than done but that's the whole idea of practicing.On your right hand, I would not worry that much about wrist vs. elbow unless you are aiming for Guiness speed record. Wrist movement is probably a bit better but there's nothing wrong with a combination of wrist and elbow. Guitarists argue about it all the time but there are superb guitarists in both camps which proves that both techniques are equally viable. Just avoid finger movement, it does not work for fast playing

What Is WiFi? Just Tell Me What It Is, and What It's Used For.?
Wi-Fi= wireless fidelity and what everyone else said1. i want to acess internet on my psp and my pc.i heard about this wifi link.i don't what a wifi is.plz help?you are not going to get free internet. if you want internet you have to pay for it. all Wi-Fi is, is you plugging a router into your internet connection, then the router transmits a signal.2. What WiFi router should I buy for my 800 SF apartment?Any wifi router provided by the internet provider will do and serve the purpose...An apartment area of 800 sq. ft is small enough which can easily be served by the company provided hardwares!You would not want to have a very strong signal that anyone outside your apartment can tap into!3. What is wifi and how do I know if my house has it?Wi-Fi is a wireless internet connection that things like laptops, wireless cards, and game systems use connect to the internet. If you do not have a wireless router, you do not have Wi-Fi4. What Wifi usb Adpter Is Better?Neither, they are both low quality. Buy from a reputable brand5. what is wifi actually? how does it works?it's a wireless connection. you can connect any computing device as long as you have a wireless nic enabled on that certain device. to access the internet you need to be in a "hotspot" that's the place where you can get your signal to connect to the internet6. How can I find out what Wifi networks my iPhone knows about?I think the only way is to actually be in range of the network that you want to get rid of. You can not actually see what networks you have stored, not that I know of, but if you want to get rid of a network.Settings > Wifi > Then select the blue arrow on the right of the network that you are connected to and click "Forget this Network".7. How do I find out what wifi chipset my phone has?I simply used the dmesg command in a terminal emulator and scrolled until I found anything named bcm432x... and wlan. Think thats it. I have lg p5008. I'm not entirely sure what WiFi is?Have a look at the wikipedia article. Usually you would get a DSL connection and set up your wireless network at home. The wireless network connection is also called W-LAN or WiFi, but in this context, WiFi has nothing to do with the ISP. Not sure if in your region any provider sells internet acces via WiFi, this is not a common thing to do.9. What is wifi and what does it do for a phone?If you have internet at home and have a wireless router you can connect wirelessly to it and get on the internet etc. on your phone. Hope this helps!10. 802.11 standards compliant methods of forming a LAN. Unlike Ethernet, data does not travel along a cable, but rather, wirelessly, at a frequency of 2.4GHz (802.11b/g) or 5.0GHz (802.11n and the antiquated 802.11a)11. What is "WiFi" and can you explain ,more about it? I'm GOnna buy a laptop.?well if you want wifi in your home you have to have an internet connection threw a modem..ex comcast, qwest, at&t. you will need to purchase a wireless router, its just another device that hooks into your modem. so no it is not free, but it is a one time charge because your ISP will not charge you to have the wireless router hooked up...and where you can use it is in your home. you can also connect to wifi at places like starbucks, and that is free as well.12. What WiFi router brands or models are considered to be secure? [closed]For cheap solution I use a wifi router well supported by dd-wrt alternative firmware. Here you can find supported models database.For more advanced, trouble-safe solution I use Ubiquiti UniFi - the AC-Lite model is really good.13. What is a bluetooth? what is WIFI? And what is a BLU RAY DVD?Bluetooth is a wireless technology for connecting electronic devices to each other. For instance there are Bluetooth Headphones, Bluetooth Cell Phone Ear Pieces, etc... If you want to be able to use the Bluetooth Ear Pieces with your cellphone, your cellphone must be Bluetooth compatible. WiFi is a method of connecting to the internet wirelessly. For instance many big cities may have "WiFi Hotspots". If you are in these WiFi Hotspots and you have your laptop or any other device that can connect to the internet wirelessly, you can surf the web wirelessly as long as you are in that particular area. And Blu-Ray is Sony's High Definition format disc. The difference between Blu-Ray and Regular DVD is that Blu-Ray can produce 1080p HD quality picture and Blu-Ray can hold more data. A Single Layer Blu-Ray disc can hold 25GB and a Dual Layer DVD can hold 50GB. A standard DVD can only hold around 8.5GB total. Basically if you have a HDTV, Blu-Ray would be the best choice for getting the best picture quality with clear, crisp viewing quality.
Which Is Better, WiFi Or ZigBee Wireless Technology
Which Is Better, WiFi Or ZigBee Wireless Technology
Wireless replacing wired has become an irreversible trend, which can also be said to be a new industry. At present, there are two technical camps of ZigBee and WiFi in the field of smart home, and WiFi and ZigBee have their own advantages in wireless technology. Among the most popular wireless technologies in the industry, WiFi technology and ZigBee technology are the most worthy of competition. So which is more advantageous, WiFi or ZigBee? Who will become the mainstream in the future? This is worth discussing.WiFi: WiFi technology is the fastest transmission technology at present. The product cost is low and it is more popular in current life. However, the devices that can be connected with WiFi are limited. The actual scale of adding WiFi network to devices generally will not exceed 16. In the development of, the number of switches, lighting and home appliances will certainly be far more than 16, so WiFi has its advantages, but it has great limitations, Limited development.ZigBee is a two-way wireless communication technology with low complexity, high security and short-range transmission. It has the characteristics of strong scalability and can be embedded in various household devices. ZigBee also has advantages in security.1. The future smart home network will be a smart network, which can sensitively perceive the changes of data and traffic of each node; Be able to intelligently allocate, repair and deal with network resources; It has the attribute of "self-learning and self-organization".. However, in the practical application of families, switches, lighting, curtains, anti-theft devices, etc. will not move after installation.2. ZigBee supports up to 65000 nodes, but can WiFi connect more than 100 devices? The answer is No. So large capacity is good.For example, LVMI smart home, that is, Xiaomi's smart home brand, basically supports ZigBee protocol.When it comes to LVMI, I recommend their smart gateway. The smart home market is very messy. Sometimes we are excited to buy it and find that it does not support it. Therefore, when we buy it, we should see what the device supports or does not support. Of course, the best thing is to buy a gateway with high compatibility. LVMI's gateway product not only supports ZigBee protocol, but also is compatible with homekit. This product supports 32 aqara devices of green rice, which can be connected with Apple's "home" app. After that, it can control the associated devices on IOS devices and Siri directly. I think most young people now use fruit machines to compare prices. In this way, it is still very friendly to most IOS users. For fruit powder users, the biggest advantage of this product is price. At present, the smart home products supporting homekit on Apple's official website are very expensive. Even a simple smart socket costs 295 yuan. Through the aqara gateway of LVMI, the cost of access equipment can be reduced.Well, comprehensive comparison, WiFi is relatively more convenient, but ZigBee will be more stable and support more devices. If you only want to use one or two smart devices, WiFi can be used. If you want to create a complete set of smart home ecological chain, it is obvious that ZigBee is more in line with your requirements. Xiaobian is more optimistic about ZigBee. After all, home is developing towards the trend of comprehensive intelligence, Technology with multiple devices can ensure this. No matter what kind of technology, we hope to constantly update and improve, and making our products convenient is the king.
Smart Home Promotes Building Intercom into Thousands of Households, with Large Stock and Incremental
Smart Home Promotes Building Intercom into Thousands of Households, with Large Stock and Incremental
In the large densely populated cities of Beijing, Shanghai, Guangzhou and Shenzhen and the rising second and third tier cities, the housing demand is increasing year by year. The huge floating population not only promotes the rapid development of low-end real estate resources in the first tier cities, but also extends the complex industrial chain around the buildings. In particular, the development slogan of "smart city" put forward by the state in recent two years gives hope to the market that lives on security products around buildings in addition to real estate developers.Smart home promotes building intercom into thousands of householdsAt present, more and more building intercom manufacturers begin to go deep into the field of smart home and combine building intercom system with smart home system. This is reflected in the construction of "digital building" and "smart home industry ecosystem":Combined with the smart home system, in addition to the traditional intercom unlocking function, the building intercom also integrates many convenient functions such as SMS notification, mobile app remote control, security alarm, indoor monitoring and viewing, elevator call, home control, information home and so on.Building intercom and smart home complement each other, further improving the value-added space and cost performance of both, thus bringing huge space for function expansion.In the future, it is expected to take advantage of the upsurge of smart home to develop rapidly in the wave of home intelligence, and will carry more home control functions.Smart community derived demand brings new business opportunities for building intercomIn addition to the smart home, the building intercom system, as the entrance of the smart community, realizes the extension of multiple functions such as identity confirmation, access control, security monitoring, human-computer interaction and so on by combining AI technology.The consumer demand derived from the smart community can be said to bring new business opportunities to the building intercom industry. In the process of continuous promotion of the smart community, many building intercom enterprises see the future business opportunities and begin to make corresponding layout and planning on products and solutions. Using information means, Internet and Internet of things technology, develop community oriented Internet of things system and information platform, and provide real-time, fast, efficient and low-cost Internet of things, interconnection and intelligence for the community on this basis. For example, it launched smart community management, smart life services, smart travel and other related solutions, and continued to pay attention to the field of community and personal security.High, middle and low-end take all stock and incremental market space is largeAs an upstream industry of real estate, building intercom has significantly increased the demand for medium and low-end building intercom products under the condition that the state vigorously promotes the construction of affordable housing and indemnificatory housing.With the implementation of smart city construction, the demand for high-end building intercom products is also increasing day by day. The application of high-definition visualization and face recognition in the field of building intercom is accelerating.At the same time, after more than 20 years of development, many communities equipped with building intercom in the early stage are facing problems such as disrepair and backward configuration. Therefore, the equipment renewal demand of old communities has also become a new round of market growth point of building intercom system.Overall, China's housing market will continue to develop. According to the relevant development strategies of the State Council, China will build 10 billion square meters of housing by 2020. For building intercom enterprises, there is a large development space for building intercom related products in both stock market and incremental market.Conclusion: in a word, opening up the integration and docking with comprehensive life service platforms and community operation platforms such as third-party payment, smart city, video surveillance, community o2o e-commerce, smart home and community elderly care, that is to provide overall solutions for communities and families, which has become the future development trend of deepening reform, transformation and upgrading of building intercom enterprises. Moreover, with the gradual improvement of community infrastructure, building intercom enterprises also need to change from the role of product provider to the role of supporting service provider.
Upgrading of Set Top Box
Upgrading of Set Top Box
Cable STB From 1990 to 2005, the first generation set-top box, also known as analog TV set-top box, dominated the family living room for 15 years. However, due to the unidirectional content and low definition, it also replaced as the second generation set-top box - Digital TV set-top box as CRT TV withdrew from the historical stage. Although the definition of digital TV set-top box has changed greatly, the unidirectional content of both the first and second generation set-top boxes still fails to meet the needs of users. However, the second-generation TV set-top box still has a very large market. It carries the main way of radio and television live broadcasting. It has been in service until today. With the popularization of Internet and triple play, the second-generation TV set-top box has added interactivity.IPTV set top boxIPTV (Internet Protocol Television), namely network protocol television, is a technology that uses broadband network and integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive video services, including digital TV. Its three major functions of live broadcasting, watching back and time shift turn the originally linear TV programs into a nonlinear program stream. Users can choose programs instead of watching programs, which is a great subversion to the viewing habits of traditional cable TV users. In 2004, China's IPTV was jointly launched by Heilongjiang Unicom (formerly Netcom) and Shanghai Wenguang blockbuster in Harbin, and then expanded to other provinces and cities in China. After the exploration stage from 2004 to 2008, the launch stage from 2009 to 2012 and the promotion stage from 2013 to 2017, IPTV has developed very rapidly in China.Ott boxNetwork STB began to rise in 2005, also known as Ott box.
