| Abstract: | 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. |

| Keywords: | wireless video transmission system sampling interpolation rate control |
