Error resilience methods for FGS coding scheme

In the FGS (Fine Granularity Scalability) enhancement bitstream, the error resilient technique are not considered. When delivering video bitstream over error prone channel, the actual decoded bits are only a small part of received data due to the transmitted errors even if a great deal of enhancement bitstream is transmitted to the decoder. A new architecture of enhancement layer bitstream with resynchronization markers and Header Extension Code (HEC) is proposed for efficient error localization and recovery. Experimental results show that, at the same channel conditions, the architecture the proposed enhancement bitstream is more robust than that of the original enhancement bitstream in MPEG-4 standard.
