The security technology industry is the basic industry of national security. The development of the video surveillance industry from the earliest simulation system to the current network system is the driving force of user demand and the witness of technological progress. Vision is one of the main ways people get information, and images and videos play an important role in the interaction between people and computers. After entering the 21st century, we are facing a rapidly developing information age. Digital image and video information has the characteristics of massive data, which brings great difficulties to the storage and transmission of data. However, the previous audio and video compression technology is obviously insufficient, so it is urgent to solve this problem. The researchers further developed and upgraded the compression encoding and decoding technology, and developed a AV Over IP network digital decoding matrix in H.264 format.

The core function of the H.264 format network digital decoding matrix is to compress video efficiently. When the resolution is not very high, H.264 solves the storage problem brought by big data very well. Its compression performance has been greatly improved, and the system is more complete. In response to users' requirements for high-definition, we have upgraded the current H.264 format monitoring network matrix to an H.265 format monitoring network decoding matrix similar to H.264 encoding and architecture, which improves compression efficiency, error correction and recovery capabilities. The real-time transmission time is reduced, the information acquisition time is reduced, and the complexity is reduced. When transmitting the same image, the bit rate of H.265 is reduced by half, and the video quality is better than that of H.264 encoded video, which brings a better intuitive feeling to people's subjective vision.

The wide application of video technology, in the case of a large amount of data, not only realizes the expansion of memory storage, but also requires effective compression technology to greatly reduce the amount of information data, storage and transmission form compression, which can save costs and storage. space, and improve the transmission efficiency. Through the AV Over IP network digital decoding matrix, high-quality audio and video presentation can be realized on the display screen, which is stable and simple, and provides a strong security guarantee for users.
