Cross-layer optimized transmission of H.264/SVC streams over DVB-T2 broadcast system

摘要

DVB-T2 has been recently standardized by the DVB organization. In this paper the deployment of H.264/SVC in DVB-T2 is discussed. We focus on the system configuration aspects which provide optimal use of DVB-T2 features from the H.264/SVC point of view. We also propose modifications to the error protection mechanisms that would consequently lead to an improvement of user experience. The data dependencies in H.264/SVC are exploited to protect the media data unevenly according to their priorities.
