Abstract
A wireless communication system for video packet transmission is provided. The wireless transmission system includes a video encoder for encoding a video signal on a block-by-block basis, and a degree of importance determiner for determining the degree of importance of video data encoded in each block from predetermined parameters. The wireless transmission system also includes a data transmission determiner for determining the transmission priority, or whether to transmit the encoded video data, on the basis of at least the amount of encoded video data to be transmitted per unit time the wireless channel conditions, and the degree of importance of the encoded video data. Furthermore, the wireless transmission system includes a video data packetizing unit for packetizing the video data determined to be transmitted, and a wireless transmitter for wirelessly transmitting packetized data. It is possible to transmit the video data with the amount of the data controlled for the fixed bandwidth of the wireless channel by determining the transmission priority or whether to transmit the video data, by considering the degree of importance of the currently encoded video is data. Therefore, when the bandwidth of the allowed channel is small and the amount of data to be transmitted per unit time is large, it is possible to transmit the video data faster since the video data is not buffered unlike in the conventional technology.
