摘要： Program clock references in first and second MPEG data streams are re-stamped in accordance with delays introduced into the first and second MPEG data streams. Accordingly, the program clock references in the first MPEG data stream are re-stamped according to a variable delay in the first MPEG data stream, and the program clock references in the second MPEG data stream are re-stamped according to a variable delay in the second MPEG data stream. The re-stamped program clock references in the second MPEG data stream are corrected according to a fixed delay in the second MPEG data stream. The first and second MPEG data streams are multiplexed, and the multiplexed first and second MPEG data streams are transmitted and received.

摘要： A repeater receives an input signal containing mobile/handheld (M/H) data received in an M/H frame equivalent in size to 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 input signal, is received and demodulated to produce an MPEG transport steam. Frame registration is found so as to find data and field syncs in the MPEG transport steam. The trellis encoder is reset prior to the M/H training data in to the mobile data stream. The data is VSB modulated, the field syncs are added to the modulated data to reconstruct the M/H frame, and the M/H frame upconverted to an RF output signal. The RF output signal is retransmitted.

摘要： 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.

摘要： A hybrid television signal of less transmission power or better signal to noise performance is made up by removing low frequency analog components from the video signal, digitizing them and sending them as data in non-active video portions of the transmitted signal. A two step hybridization process, with the first step removing the line averaged value of the video components of the video signal and the second step removing the remainder of the video components under 200 KHz, is described. Temporal filtering, signal pre-emphasis, compression, time dispersion and double sideband suppressed carrier modulation about a centered carrier are disclosed for reducing peak signal amplitudes and for minimizing co-channel interference to and from NTSC signals. Time dispersion is done horizontally, vertically or both to reduce the peak signal amplitudes. Time dispersion in conjunction with low frequency removal and temporal filtering is preferred. Time dispersing lower frequencies more than higher frequencies contributes to an optimized video display. The resultant signal system is uniquely adapted to a high definition television signal in a limited frequency channel with an NTSC signal.
