摘要： Disclosed are a distributed video encoding/decoding method and a distributed video encoding/decoding apparatus, which can improve loss resilience and the quality of service. The distributed video encoding 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, encoding the video data to be transmitted by performing motion predictions according to the determined number of motion prediction performance steps, and channel-coding the encoded 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.
