Abstract:
1. A method of processing mobile/handheld (M/H) data received by a receiver in an M/H frame equivalent in size to 20 VSB data frames, wherein each VSB frame contains an odd VSB field and an even VSB field, wherein each of the VSB fields includes one field sync segment and 312 data segments, wherein the M/H frame includes randomized main data and non-randomized M/H data, and wherein the non-randomized M/H data has more robust coding than the randomized main data, the method comprising: receiving a transmitted M/H frame by a receiver and in the second path, finding frame registration so as to find a structure of the M/H frame in the MPEG encoded transport stream; in the second path, based on the structure of the M/H frame, correcting the representation of the M/H data; in the second path, based on the structure of the M/H frame, locating block mode data within the correctly represented M/H data; and in the second path, decoding the correctly represented M/H data using the block mode data.
