Abstract
Mobile/handheld (M/H) data is received in an M/H frame equivalent in size to exactly 20 VSB data frames. Each VSB frame contains an odd VSB field and an even VSB field, and each of the VSB fields includes one field sync segment and 312 data segments. The M/H frame includes main data and M/H data, and the M/H data has more robust coding than the main data. The M/H frame is received and an MPEG encoded transport stream derived therefrom is outputted. Frame registration is found so as to find a structure of the M/H frame in the MPEG encoded transport stream. Based on the structure of the M/H frame, the M/H data is randomized. Based on the structure of the M/H frame, block mode data is located within the randomized M/H data. The M/H data is decoded using the block mode data.
