"Security Monitoring Digital Video Video Decoding Technical Requirements" GB / T25724-2010, also known as SVAC standards, jointly led by the Ministry of Public Security, Ministry of Industry and Information Technology, National Standards Committee, with the audio and video standard of my country's independent intellectual property rights, real Autonomic controllation is achieved in the sense.
"Public Safety Video Surveillance Digital Voice Code" GB / T25724-2017, instead of national label GB / T25724-2010, officially implemented on June 01, 2017, is gradually improved on the basis of the 2010 version The SVAC standard version 2.0, more secure security in data security, the image coding efficiency is further improved, catching H.265, and the information security level is also higher.
As an audio and video codec technology standard with autonomous property rights in the industry, the impact of SVAC has far-reaching. The national security chip industry that will continue to tend to be weakly introduced into new vitality, but also maintain good driving force for the development of the security national brand.
The promulgation of the SVAC standard solves the practical problems faced by the monitoring video and audio encoding, which is in line with the needs of my country's security monitoring applications, with my country's self-intellectual property rights. SVAC standard development work is conducive to achieving breakthroughs to international standards in the security field.
The SVAC standard is the basic technology of security digital, high-definition, intelligent. The core of the SVAC standard is that it is not only for monitoring actual needs, solving the actual problems faced by monitoring audio and video coding; and can be faithful to the audio and video coding of the scene. With the premise of ensuring audio and video quality, the SVAC standard can provide higher coding efficiency; in the premise of equivalent performance, the specific algorithm preferentially adopts a plan with domestic independent intellectual property, and has a flexible scalable architecture.
As the basic standard for the video surveillance system, SVAC will provide strong technical support for the construction of the urban social security comprehensive prevention and control system. On the one hand, it can solve the current video monitoring system's interconnected system is difficult to interconnect. Question; On the other hand, it is possible to propose an appropriate response program for security special applications, and solve the problem of current video surveillance field can only use radio and television standards and unable to meet the security special needs.
The rapid development of digital video surveillance market has brought new opportunities to chip suppliers. In terms of digital signal processing, simulation power supply, monitoring platform, major chip suppliers have stepped up research and development, continuously introducing new products to seize market opportunities. There is a data showing that a few years ago, the cost of the digital network HD camera in 720p has a cost of seven or eight thousand yuan. With the maturity of Haisi, Ti, Adi and other companies, chip costs continue to decrease, now numbers The cost of HD network cameras will be greatly low. From the perspective of clarity, 1080P has begun to enter the practical phase.
The continuous introduction of new technologies, new products and new services in the security industry, its application and popularity speed, derived a large number of new needs, greatly expanding the development space of security chip industry. The decline in the use threshold makes the video surveillance equipment are no longer limited to banks, traffic, and peaceful cities such as industry users, but will drive the rapid development of civilian markets, thus making the security monitoring industry, the larger, market prospects .
