一、安防对视频编码技术提出更高要求1.安防领域高清化成必然趋势安防领域高清化已经成为必然趋势,720P、1080P视频已广泛普及,监控领域4K高清视频也在逐年增加,由此带来的视频内容增长速度将远远快于网络增长速度,带宽相对不足的问题将长期存在。同时,随着视频内容的增长,存储成本会大大增加,因此,安防监控领域对下一代编码算法的首要要求便是在现有基础上进一步提高压缩比。相对于标清视频,高清视频的信
First, the security of video coding technology put forward higher requirements 1. Security into the inevitable trend of HD into the field of security HD has become an inevitable trend, 720P, 1080P video has been widely popularized, the field of monitoring 4K HD video is also increasing year by year, bringing Video content will grow faster than the speed of network growth, the problem of relatively insufficient bandwidth will exist for a long time. At the same time, as the video content grows, the storage cost will increase greatly. Therefore, the primary requirement for the next generation of coding algorithms in the field of security monitoring is to further increase the compression ratio based on the existing base. Relative to SD video, high-definition video of the letter
