| Abstract: | Firstly, on the basis of analysis for video compression standard H. 264/AVC, DSP TMS320C6416 and ARM microcontroller are used to implement a flexible compressed platform with high quantity embedded digital video. Then the principle of system structure, hardware design and encoding algorithm in are illustrated details. This platform combines computation ability of DSP with networking transfer and remote control ability of embedded MCU, which satisfies the demand of complicated and various compressed algorithm, and supports the interconnection of RTP/UDP/IP protocols. Application in scenario of industrial ethernet shows that its PSNR is very excellent. |
