The HD IP Cameramonitoring technology barriers

The HD IP Cameramonitoring technology barriers
1, H.264 codec technology
The key to the popularity of high-definition IP Camera surveillance is the quality of the video codec, compression rate and network adaptability. HD IP Camera codec core needs are: minimize the bit rate at the same time, to obtain the best possible image quality. Network monitoring system mainstream codec is H.264, H.264 using a motion vector prediction value, the motion vector difference coding Columbus index encoding, the encoding is characterized by the smaller the value, the more bits less.
With the substantial increase in the amplitude of the motion vector H.264 IP Cameras for motion vector prediction and coding method of compression ratio will be gradually reduced, then with the video surveillance from SD to HD full forward, H .264 slightly inadequate.
But now a mainstream technology H.264 there will be a lot of limitations in the day-to-day infrared IP Camera surveillance, has been unable to meet the needs of the people in the high-definition network surveillance system, the emergence of H.265 has brought new hope. Tested, in the case of the same quality with H.264, H.265 obtained to gain an average of 6.1% of the compression, complicated image compression gain can be increased to even 20%. H.265 video compression algorithm standard efficiency than H.264 by about half, under the premise of ensuring the same video image quality, the bit rate of the video stream is reduced by 50%,
Can achieve transmission speeds of 1 to 2Mbps transmission 720P. The H.265 technology video compression than H.264 increased by 30 to 50% according to estimates potential investment savings up to 20%, is very impressive. However, the promotion of H.265 is also a gradual process.
2, high-definition monitors network traffic
HD IP Cameramonitoring system, the transmission on the IP network is a large number of video and audio signals, these signals characteristic is a liquid media, liquid media with the IP network is only recently a large number of emerging applications, initially, IP network design say it is not tailored to the transmission medium for the liquid medium of the surveillance video, the video stream transmission, the quality of service in such networks will be very difficult to guarantee.
Also, because the high-definition IP Camera video surveillance need to stream video large amount of data, network transmission can really do all packets arrive at the receiving terminal smoothly? Whether or not in the process of transmission dropped frames? Depending on the video surveillance business the right to speak in a variety of business IP-based network video surveillance business gradually become an important business in the IP applications, then I believe in the technology research and development will intensify our efforts to solve the technical barriers exist in high-definition network monitoring system . Due to the high-definition video surveillance video streams need to transfer the amount of data, if the network transmission cost is too high, will also affect the promotion process.
