摘　　要：为解决无线视频传输带宽较窄且不稳定的缺点,在编解码时转换视频分辨率即编码时抽取、解码时内插来降低传输的码率,并在抽取前进行预滤波以减少混叠,同时对视频的码率进行有效的控制,从而保证了较好的图像质量。To solve narrow and instable bandwidth of wireless video transmission, video resolution is converted firstly, that is to say, sampling when encoding and interpolation when decoding. Before sampling, pre-filter must be done to reduce aliasing. At the same time, effectively control the video rate should be taken to ensure better video qualities.
