Latest Patents
Xiang Wan's latest patent involves a system and method for performing forward error correction on an MPEG-2 transport stream. This invention addresses the need for optional error correction information embedded within the transport stream. The method includes performing an error correction operation on a super group of packets within the transport stream. The error correction data is inserted into a created trailer group of MPEG-2 compliant transport stream packets that contain no payload, but only an adaptation field. These trailer group packets are optional and can be discarded by a standard MPEG-2 decoder. However, they can also be utilized to recover data lost during the transmission of the transport stream. This innovation results in a system and method that can correct an MPEG-2 transport stream applicable to any digital video broadcast (DVB) format, eliminating the need for error correction decoders specific to the DVB format.
