Claim Text:
1. A method performed by an apparatus to receive and process forward error correction (FEC) encoded video data in a mobile digital television (DTV) data burst, the method comprising: detecting a joint identifier flag in a reserved portion of a data field of the data burst, wherein the joint identifier flag indicates whether the data field contains preamble training data and provides a code rate associated with data in the data burst, wherein said data burst contains a plurality of data fields, said reserved portion is not FEC encoded, and said preamble training data comprises a plurality of packets and is FEC encoded; performing equalization of the FEC encoded video data by an equalizer using the preamble training data, said preamble training data being used to train the equalizer before processing of subsequent FEC encoded video data; and performing iterative FEC decoding of the FEC encoded video data by an iterative FEC decoder using the preamble training data and the code rate, said preamble training data being used to train the iterative FEC decoder before processing subsequent FEC encoded video data.
