摘要： An apparatus for receiving a digital data stream includes a demodulator that receives a digital data stream including alternating information and parity blocks. The apparatus demodulates the digital stream. An equalizer compensates for distortions in the digital data stream to generate a compensated digital data stream. A delay buffer generates a first stream of digital data representing the compensated digital data stream and a second stream of digital data representing the compensated digital data stream delayed for a predetermined period of time. A forward error correction block receives and processes the first and second streams of digital data from the delay buffer, and outputs an error corrected stream of digital data. A transport block receives and processes the error corrected stream from the forward error correction block for display.

摘要： A trellis decoding system (1) for use in processing a High Definition Television signal. The trellis decoding system includes a traceback unit (33) that identifies a sequence of antecedent trellis states in accordance with a state transition trellis. A branch metric computer (2) includes eight discrete subunits (3), one for each possible trellis state. Each subunit (3) generates two output bits (14, 15) indicative of the two trellis branches exiting the trellis state represente by that particular subunit (3). An add-compare-select unit (8) includes eight discrete subunits (23), each associated with a particular trellis state. Each subunit (23) includes as an input two bits (28, 29) received from the branch metric computer (2) and as an output two bits (6, 31). Bit 31 is chosen from 28 and 29. Bit 6 is chosen from the branch metric information (26, 27) input to each subunit (23). A traceback control and memory unit (33) includes an N to 1 multiplier (49) which receives as an input the output bits (6, 31) from the add-compare-select unit (8). The present system offers a hardware reduction from prior art.

摘要： A concatenated equalizer/trellis decoding system for use in processing a High Definition Television signal. The re-encoded trellis decoder output (6), rather than the equalizer output (19), is used as an input to the feedback filter (8) of the decision feedback equalizer (4). Hard or soft decision trellis decoding may be applied. In order to account for the latency associated with trellis decoding and the presence of twelve interleaved decoders, feedback from the trellis decoder to the equalizer is performed by replicating the trellis decoder and equalizer hardware in a module (1) that can be cascaded in as many stages as needed to achieve the desired balance between complexity and performance. The present system offers an improvement of between 0.6 and 1.9 decibels. Cascading of two modules (1) is usually sufficient to achieve most of the potential performance improvement.

摘要： An apparatus for decoding digital data includes a processor to create a priori information for insertion to a maximum a posteriori (MAP) decoder. The processor detects locations of symbols in the input data stream and reads ROM data corresponding to the location. The ROM data is used by the processor to generate a priori information suitable to the input data stream location and inputs the created a priori information into a MAP decoder to aid in the decoding of digital data that is organized in digital symbol blocks of size S, wherein the data stream is encoded by a digital encoder processor comprising a plurality of deterministic digital processing units followed by a trellis encoder.

摘要： A method of synchronization correction includes receiving a digital data stream including a plurality of data bursts. A field sync representative of a first field of a data burst is detected. The number of symbols in the first field is counted. The number of symbols counted in the first field is compared to an expected number. If the number of symbols counted is determined to be less than the expected number, then a field sync of a second field of the data burst is delayed. If the number of symbols counted is greater than the expected number, then the field sync of the second field of the data burst is advanced.

摘要： A variable latency maximum a posteriori (MAP) decoder inputs an encoded stream of M interleaved trellis encodings. The MAP decoder includes a metric generator unit, an alpha unit, a beta unit, and a log likelihood ratio unit that computes output values corresponding to the digital data using the accumulated alpha state metrics and accumulated beta state metrics. The processing block size per decoder, expressed in symbols, L pb , is selectable to provide either a low latency processing time or a high latency processing time in computing the output values. The decoder operates under the conditions that N*S is a multiple of D*M*L pb where M, N, and D are integer numbers greater than or equal to 1 and the input data stream is organized in digital symbols of size S.

摘要： A transmitter comprises an ATSC (Advanced Television Systems Committee) modulator and an auxiliary channel (AC) discrete multitone (DMT) modulator. The ATSC modulator provides an ATSC signal for broadcast in a channel for communicating a high definition television (HDTV) service. The DMT modulator receives auxiliary data for the HDTV service and modulates this auxiliary data to provide an AC signal for broadcast in the same channel, i.e., the AC signal is a co-channel interfering signal to the broadcast ATSC signal. In particular, the DMT modulator modulates the auxiliary data such that the AC signal imitates one, or more, spectral properties of an NTSC (National Television Systems Committee) broadcast signal. In a complementary fashion, a receiver comprises an ATSC demodulator, for recovery of a high definition television (HDTV) signal, and a discrete multitone (DMT) demodulator, for recovery of the auxiliary data.
