随着现代社会对于安防领域需求的日益激增,以及该领域内相关技术的不断发展,视频监控产业正处在高速的发展期。目前中国市场仍以模拟摄像机为主,这就使得以网络视频编码器为代表的网络视频监控系统使用率一直居高不下。以往的多路网络视频编码器,往往采用多片DSP外加CPU(ARM、PowerPC)来实现,系统架构复杂并且成本高。采用单片DM8165实现4路D1格式的全实时H.264和MJPEG双码流视频编码,降低系统设计的复杂度和整板BOM成本,并缩短产品开发周期。
With the increasing demand for security in the modern society and the continuous development of related technologies in this area, the video surveillance industry is in a period of rapid development. At present, the Chinese market is still dominated by analog cameras, which makes the network video encoder represented by the network video surveillance system usage has been high. Multi-channel network video encoder in the past, often using multiple DSP plus CPU (ARM, PowerPC) to achieve, the system architecture is complex and costly. Realize real-time H.264 and MJPEG dual-stream video encoding with 4 channels of D1 format with single chip DM8165, reduce system design complexity and entire board BOM cost, and shorten product development cycle.
