Abstract:
1. A method by which television transmitters of 8-vestigial sideband (8-VSB) digital modulation of a single radio-frequency carrier wave broadcast mobile/handheld (M/H) data for reception by mobile radio receivers, the method comprising: coding the M/H data to generate concatenated convolutional coded (CCC) data; time-division multiplexing the CCC data within the 8-VSB digital modulation such that the CCC data are transmitted in a plurality of M/H Groups disposed in respective slots within sub-Frames of successive M/H Frames, each one of the successive M/H Frames having a duration equal to that of twenty frames of 8-VSB symbols and being divided into five successive sub-Frames respectively, each of the sub-Frames being of a duration the same as the others of them; and having each current sub-Frame of one of the successive M/H Frames incorporate a respective one of a plurality of Transmission Parameter Channel (TPC) signals in each one of the plurality of M/H Groups therein; wherein the respective one of the TPC signals includes a respective plural-bit indication of a current total number of M/H Groups included within the current sub-Frame of one of the successive M/H Frames.
