Layer-Aware Forward Error Correction for Mobile Broadcast of Layered Media
The bitstream structure of layered media formats such as Scalable Video Coding (SVC) or Multiview Video Coding (MVC) opens up new opportunities for their distribution in Mobile TV services. Features like graceful degradation or the support of the 3-D experience in a backwards-compatible way are enabled. The reason is that parts of the media stream are more important than others with each part itself providing a useful media representation. Typically, the decoding of some parts of the bitstream is only possible, if the corresponding more important parts are correctly received. Hence, Unequal Error Protection (UEP) can be applied protecting important parts of the bitstream more strongly than others.
