摘要： A variable length codeword decoder is responsive to a clock signal having multiple cycles and includes a source of sequential variable length codewords, each representing a run-length encoded codeword. A barrel shifter circuit is coupled to the codeword source and provides the next undecoded variable length codeword in lesser significant bits of its output terminal. A codeword decoding circuit is coupled to the output terminal of the barrel shifter and operates to decode two sequential variable length codewords, representing respective zero run run-length codewords, in a single clock cycle; or two sequential variable length codewords, a first representing a zero run run-length codeword and a second representing a one run run-length codeword, in a single clock cycle; and all other variable length codewords in a single clock cycle.

摘要： A method and apparatus for staggercasting a plurality of content representative signals includes encoding a first and a corresponding second signal representing each of the plurality of content representative signals. A composite signal is generated comprising the plurality of first and second encoded signals. In the composite signal, each respective second encoded signal is delayed with respect to the corresponding first encoded signal. The first and second encoded signal representing a selected one of the content representative signals is extracted to reproduce the selected content representative signal. The extracted first encoded signal is decoded if an error is detected in the extracted second encoded signal, otherwise the extracted second encoded signal is decoded. When a different content representative signal is newly selected, the first extracted encoded signal is decoded until the delayed second extracted encoded signal is available.

摘要： A data storage element comprising a substrate and a data track disposed on the substrate, the data track comprising a plurality of data sectors, each of the data sectors being formatted in accordance with a first digital data standard and comprised of a control data portion and a payload data portion, each of the payload portions including a plurality of data packets formatted in accordance with a digital television standard. In particular, the data packs correspond to program stream packs specified in the DVD standard and the data packets correspond to transport packets specified in the ATSC standard. The present storage element enables the data stored thereon to be read by a conventional DVD front end and provided to an ATSC receiver without processing the contents of the transport packets. Therefore, the present invention allows ATSC data to be stored on a DVD disc and to be provided in a manner that can fully realize the display capabilities of the ATSC receiver. The present invention is particularly advantageous in HDTV applications.

摘要： In a digital broadcast communications system, a higher priority component and a lower priority component are broadcast from a transmitter to a receiver. Each of these components generates a main and a supplemental signal, and each supplemental signal is advanced in time with respect to the corresponding main signal. The main and supplemental signals for both the higher and lower priority components are combined into a single signal, which is broadcast to a receiver. In the receiver, the time advanced supplemental signals are stored in a buffer to time align them with their corresponding main signals. Both main signals are processed in the normal manner in the receiver, and are also monitored to detect a fading event. When a fading event is detected, the corresponding buffered supplemental signals are substituted for the faded main signals and normal processing continues.
