DISTRIBUTED VIDEO CODING/DECODING METHOD, DISTRIBUTED VIDEO CODING/DECODING APPARATUS, AND TRANSCODING APPARATUS

摘要

Disclosed are a distributed video coding/decoding method and a distributed video coding/decoding apparatus, which can improve loss resilience and the quality of service. The distributed video coding method first involves checking the state of a channel, determining a channel coding rate and the size of video data to be transmitted based on the checked state of a channel, determining the number of motion prediction performance steps based on the determined size of video data to be transmitted, coding the video data to be transmitted by performing motion predictions according to the determined number of motion prediction performance steps, and channel-coding the coded video data according to the determined channel coding rate. Accordingly, it is possible to improve loss resilience, even without additionally occupying network resources, thereby being capable of reducing the probability of decoding failure.
