Abstract
The present invention a method of transmitting video information over a communication link made of several transmission paths between wireless transmitting and receiving stations. The method comprises, in the wireless transmitting station, obtaining an uncompressed video frame made of an array of pixel blocks, a pixel in the pixel blocks being represented by base pixel information and enhancement pixel information; generating at least one set of complementary pixel blocks from a given pixel block of the obtained uncompressed video frame, by applying different operations to said given pixel block for dropping different enhancement pixel information from that pixel block, so that the complementary pixel blocks comprise different enhancement pixel information and each comprises the base pixel information; and for each set, transmitting the complementary pixel blocks over respective different transmission paths to the wireless receiving station. This provides robustness of video transmission while keeping a high quality of video rendering.
