Abstract: A novel method for video object segmentation is proposed for the purpose of packet loss resilience, which partitions a frame into foreground and background objects according to their Macroblock encoding mode. Combined with the new H.264 error resilience technique Flexible Macroblock Ordering, the two objects are put into different Slice groups that enable the independent packet loss resilience method for them. In the proposed joint source-channel coding method a more forced Intra update rate is applied on the foreground and different coding rates of channel encoding are used to the two objects with the packet loss rate. The technique presented in this paper is easily implemented and it improves the quality of video communications in the packet loss IP network effectively.
