Previously, the video compression of the Internet video industry, the transmission standard was the H.264 standard launched in 2003. This standard can reach 1080P full HD level when the video quality is permitted. With the development of semiconductor technology, after the bottleneck of H.265 computational complexity, in terms of ultra HD monitoring applications, like the MPEG-2 replaced by H.264, H.265 will inevitably replace the current H.264 Technology.
H.265 standard gradually enters better
As the user's requirements for monitoring video quality are getting more and more popular in security monitoring, thereby bringing a sharp rise in storage space and cost. Compared to the H.264 encoding technology currently being used, the high compression rate characteristics of H.265 saves half of the storage space, which significantly reduces the storage cost of the video. Compared with H.264, the maximum skill of H.265 can reduce the data transmission bandwidth to H.264 under the premise of maintaining the image quality. At the same time, it also supports the resolution of up to 76804320, so even the 2160P or even higher level of ultra HD video can also be encoded by the H.265 format.
Due to the restriction of the H.264 macroblock, the load in the video processing has also increased significantly. In the event of a high-frequency process of high-definition, some are not a feeling of feelings. Compared to H.264, H.265 improves a hierarchy in the macroblock type, the original maximum 16x16 module type is increased to macroblocks of 32x32, 64x64, or even 128x128. Thereby reducing the number of macroblocks of HD digital video, reducing parameter information for describing the contents of the macroblock, and the shaping conversion block size is also expanded, and the compression efficiency of the device is rereserved.
In addition, H.265 also uses updated motion vector testing. In addition to the above mentioned aspects, H.265 also achieves more breakthroughs in terms of multi-core parallelization, and in some new technologies such as WPP, it can make parallel degree of parallelism to meet various needs. Under the premise, it is also possible to high cost and efficient work.
Through the above technical analysis, we found that H.265 has implemented a comprehensive transcendence of H.264 in many technologies. Regardless of the function or performance, the H.265's function is almost almost improving the former, so if it appears from these aspects, the upper position of H.265 is just a problem.
However, since the operation of H.265 since the second half of last year, Today's H.265 standard is still in a concept and research stage, from the advent of the large-scale production, and then to the market's popularity is also destined to need a process. . The span, cost, and performance of this process are undoubtedly a direct influencing factor for the length of this time.
As a newborn compression standard, the cost of research and development and the price of the new product are clearly uncontrollable. But for the user, it is possible to conduct a market in accordance with its own input. And if the price of the device is too much higher than the actual cost of technology, then the market progresses clearly affected, and the screening role of the price is also destined to highlight it at this time.
In addition to the price impact, the update rate of the device is also related to the popularity of H.265. From the current application situation, in these years, in the rapid development of the monitoring system, H.264 almost owned all the markets, and many times in the work, they completed the monitoring tasks required by the user. Therefore, in the face of many H.264 devices that have just been configured, if they want to be updated in a short time, I am afraid that there is a lot of money for a lot of money. Especially for small and medium-sized users, H.265 may probably show more redundancy. In this case, the market that H.265 can enter in the early stage is very limited. And in the object, this is probably the H.265 when entering the market, is more difficult to overestimate price factors.
In short, H.265 has given our HD monitoring to our HD monitoring, although it is only a preliminary concept product, but many fields are expected to stay. From this perspective, although the current application situation is still very far from the popularity of H.265, and the birth of H.265 is also destined to have many bumps waiting for us to rely on more wisdom to solve, but h.265 In the future, the dominant position has become an unlatable fact.
H.265 open HD video or achieve new opportunities
A few years ago, the concept of HD entered the lives of ordinary people. Digital TV immediately became a few major TV manufacturers to hit the main appeal target. On the night, it seems to have a digital TV that watched HD portions became each TV manufacturer. The main appeal, but the TV manufacturer intends to ignore an important concept, which is one of the high-definition TVs only to attach the high-definition channel. Users only purchase HD TVs and cannot guarantee viewing high-definition channels, and a HD channel is also required to review HD channels. Only when using a HD set-top box, HD televisions can be derived, otherwise, HD TV is just a place in the living room. But it is undeniable that the video experience, HD is an absolute development trend.
If the high-definition experience of digital TV has a high-definition TV, the high-definition machine top box has high-definition signal, then in January this year, it was brought to the high-definition of the Internet video through the International EDU (ITU). Possible,
H.265 standard is high-efficient video coding, referred to as HEVC, is a considerable improvement and optimization in code stream, coding quality, algorithm, by providing more different tools to reduce the code rate, in equivalent bandwidth conditions Next, H.265 increases the original image quality by 50%, lead online video from VCD to Blu-ray quality, bringing new changes to the network video industry.
At present, only PPS, Xunmei video website, which supports H.265 Internet video, compared to PPS, Thunder's current technology non-autonomous research and development, said PPS-related personnel said: PPS independent research and development, the biggest advantage is , PPS's excellent technical team can modify and optimize the new version at any time according to the user experience, and use the user's first time to experience the highest quality image quality and fluency.
For the user, the service and content of the video website is the user who chooses the platform of the platform. H.265 provides an important basis for the Internet HD video, and the current Internet growth tends to have a saturated environment, PPS Can the HD road of the video website can drive the changes and growth of the entire industry?
For this reason, there are industry insiders that the improvement of HD video standards will enable the Internet video industry to compete for copyright, compete for flow to change to the technical competition, H.265 standards have highly demanded higher requirements for computers and memory, market Mass promotion also requires certain conditions, but there is no doubt that the high-quality user experience in the video field is always in the first place. Who can master higher definition, lower bandwidth transmission standards, who can win the most stable and extensive Internet users.
About H.265 standard
H.265 is a new video coding standard established after ITU-TVCEG followed by ITU-TVCEG. The H.265 standard surrounds the existing video coding standard H.264, reserves the original technologies, and improves some related technologies. New technology uses advanced technology to improve the relationship between code stream, coding quality, delay and algorithm complexity, reaching optimization settings. Specific research contents include: increasing compression efficiency, improving robustness and error recovery capabilities, reducing real-time delays, reducing channel acquisition time and random access delay, reducing complexity, etc. Since the algorithm optimization, the H265 can be achieved at a speed of less than 1 Mbps, and H265 can realize the transfer of 720P (resolution 1280 * 720) to transmit 720P (resolution 1280 * 720) to transmit the transmission speed of 1 to 2 mbps.
