Abstract
An important demand in video streaming industry today is the ability to code error resilient digital video and the error concealment techniques adopted by the video coding standards. The H.264/AVC is an emerging video standard being developed jointly by the Video Coding Experts Group (VCEG) and the Moving Pictures Experts Group (MPEG) as the Joint Video Team (JVT). This new video coding standard defines some very powerful features that make it promising for the next generation Internet applications like video streaming. Apart from significant improvements in compression performance, this standard is also more 'network friendly' and provides more features for error resilience. This is of significant importance to business applications based on real time video streaming such as video conferencing and Internet based video-on-demand, where packet losses introduced by bottleneck network links and network congestion can cause significant video quality performance degradation. In this paper, we study the error resilience techniques provided by the emerging H.264 video standard. We study the effects of slice coding on transmitted video and also analyze the concept of slice groups and flexible macroblock ordering (FMO), which are error resilience techniques adopted in the H.264 video coding standard
