Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors.

Abstract: Certain aspects of a method and system for a flexible multiplexer and mixer (FMM) are disclosed. Aspects of one method may include mixing primary audio information and secondary audio information of sampled received audio data based on corresponding metadata information to generate mixed output audio data. The generated mixed output audio data may be pulled through a plurality of pipeline stages.

Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. The present invention is operable to perform error concealment of MPEG data within various components within playback, recording, reading and writing data systems. The present invention is operable within existing systems whose components may not be capable of accommodating errors within MPEG data. Whereas prior art systems typically cannot deal with any corruption without either losing the data or suffering some operational failure, the present invention is able to conceal these errors and to continue decoding and presentation of the MPEG data. In certain embodiments, this involves maximizing the available data that contain no errors to conceal those portions of the data that do include errors. The present invention is operable to accommodate various layers while performing error concealment, including the MPEG transport stream layer, the video layer, and the audio layer.

Abstract: A system and method of verifying the format of a simulated signal produced during the simulation of an electronic circuit is disclosed. One aspect of the present invention includes a method of extracting timing information from a single simulated serial digital audio signal that comprises both data and clock. An embodiment of the present invention may verify operation of the simulated electronic circuit by setting the value of a first simulated signal according to predetermined events that occur in a second simulated signal. The second simulated signal may be parsed using timing information extracted from the second simulated signal, and the format of the second simulated signal may be matched against a predetermined format based upon the results of the parsing.

Abstract: A video and graphics system uses multiple transport processors to receive compressed data streams to perform PID and section filtering as well as DVB and DES decryption and to demultiplex them. The compressed data streams may include in-band and out-of-band MPEG Transport streams. The video and graphics system processes the PES into digital audio, MPEG video and message data. A core transport processor includes a PCR recovery module for extracting PCRs contained in the compressed data streams and for providing the extracted PCRs to a video transport processor and an audio decode processor. The PCR recovery module has a direct load capability for receiving user defined PCRs and outputting them instead of outputting the extracted PCRs. The PCR recovery module extracts PCRs from both MPEG Transport streams and DIRECTV transport streams.

Abstract: A succession of variable length data packets containing a header portion and data portion are received. Selected data from the data packet headers is stored in designated locations of a header memory. A data packet start address is provided with each stored header portion to designate a location in a data memory for commencing the storage of data contained in a corresponding data packet. The data from the received data packets is stored commencing in the data memory locations designated by the corresponding data packet start addresses. In an illustrated embodiment, the data packets are macroblocks from digitized television frames. A plurality of next data packet position indicators are provided in the data, for use in periodically verifying macroblock boundaries during the receipt of the television data and to provide a rapid recovery from a transmission error affecting the actual or identified length of a macroblock.
