Error resilient H.264/AVC video over satellite for low packet loss rates
The performance of video over satellite is simulated. The error resilience tools of intra macroblock refresh and slicing are optimized for live broadcast video over satellite. The improved performance using feedback, using a cross- layer approach, over the satellite link is also simulated. The new Inmarsat BGAN system at 256 kbit/s is used as test case. This systems operates at low loss rates guaranteeing a packet loss rate of not more than 10~3. For high-end applications as 'reporter-in-the-field' live broadcast, it is crucial to obtain high quality without increasing delay.
