Abstract

This coder includes a CPU+DSP core processor, which connects the video-decoding module respectively, the audio module and the power supply module. There are respective bi-direction connections between CPU+DSP core processor and DDR, SDRAM and ether net transferring modules. This invention possesses advantages: (1) realize H.264 hard compressing with a high data compressing ratio; (2) realize video collecting / transferring in a low quality net with low bandwidth, high error code rate and serious interfere; (3) realize real-time browsing the remote end D1 hi-quality images under a lower net speed; (4) auto-regulate the distinguishing rate / frame rate to transfer video fluently during net bandwidth changing; (5) realize hi-quality video decoding (ADC) and video parameter control; (6) realize the extension of several kinds of ports via a main processor; (7) realize video mobile sense and can take photos or video recording.

Description

technical field [0001] The invention relates to an encoder, in particular to an embedded H.264 network video encoder. Background technique [0002] From the perspective of market applications, the current application objects of network video encoders are mainly divided into two categories, namely, environmental security monitoring and bank teller system monitoring. The superiority of digital hard disk video recording technology has been gradually recognized by the domestic banking system, and major banks in many provinces have gradually introduced hard disk video recording systems to the teller system. From this point of view, more advanced network video encoder systems should have broad In the future, it will be more widely used in telecommunications, electric power, public security, customs, judicial and other departments. [0003] In applications where bandwidth is limited or in short supply, H.264 can greatly reduce network bandwidth requirements. At the same time, its ...
