The Design of 3G Wireless Network Video Acquisition System Based on the DM6446

The 3G wireless network video acquisition system based on the DM6446 is designed, which ARM side of DM6446 complete the main control functions of the system, then it calls H.264 video compression algorithm in DSP side of DM6446 through the Codec Engine, which greatly improves the efficiency of the system, and the RTP protocol control data transmission in the CDMA2000 network. The monitoring display terminal gets video resource by accessing the corresponding IP address. The experimental results show that the system designed completes wireless network video acquisition task safety and reliably, and the image is clear, also the video is coherent.
