MULTIPLE DESCRIPTION CODING VIDEO TRANSMISSION USING DE-INTERLACING MECHANISMS

摘要

Multiple Description Coding (MDC) has been shown to be an effective technique for robust transmission of video data over networks including wireless systems and the Internet. A method is provided where the video signal (20) is interlaced and split into multiple streams before being encoded and transmitted over separate transmission channels (308, 310). At a receiver (320) side, de-interlacing algorithms may be applied and the streams are regrouped to form the original video signal (20). The use of interlacing and de­interlacing techniques improve the robustness of video transmission without having to modify existing equipment.
