摘要： A data transfer system transfers frames with more than two data words from a transmitter (100) to at least one receiver (102) in a time-multiplexed manner. The transmitter (100) and receiver(s) (102) are connected via four signal lines: a clock signal (112), a serial data signal (110), a word-select signal (114) and a frame-begin signal (116). The data is serially transferred via the serial data line (110), in synchronisation with periodic clock pulses of the clock signal (112). The word-select signal (114) triggers selecting a next transmit channel register from which the transmitter (100) transmits the next data word and a next receive channel register into which the receiver (102) stores the data word to be received next. The frame-begin signal (116) triggers selecting a first one of the channel registers. The data transfer system may, for instance, be used for transferring eight digital audio channels in a DVD player between components such as an input/output interface, a filter, a (de-)coder or a digital signal processor. The data transfer system is compatible with I2S.

摘要： A method and apparatus (10) for encoding an input digital signal for lossless transmission comprising first calculation means (12) for calculating a checksum of the input digital signal. The apparatus further comprises encoding means (11) for lossless encoding into an encoded packet of digital data, and composition means (13) for adding the associated checksum to the encoded packet to form an encoded signal. Associated are a method and apparatus (20) for decoding the encoded signal, comprising extracting means (21) for receiving the encoded signal and extracting the encoded packet and associated checksum, decoding means (22) for decoding the encoded packet into a decoded packet comprising the input digital signal, second calculation means (23) for calculating a checksum for the decoded packet, and output means (24, 25) for outputting the decoded packet as an output signal if the calculated checksum corresponds with the extracted checksum.

摘要： A reproducing apparatus (1) is disclosed for reproducing an audio signal from a record carrier, the record carrier having a first digital audio signal (a PCM encoded audio signal) recorded on it in a first format and a second digital audio signal (an MPEG encoded multi channel audio signal) recorded on it in a second format. The apparatus comprises a read unit (6) for reading an information signal from the record carrier (4), a decoding unit (12) for channel decoding the information signal read from the record carrier into a decoded information signal, a keyboard (32) for receiving a selection signal and an output terminal (52) for supplying an output signal which comprises either the first digital audio signal or the second digital audio signal in response to said selection signal. An output circuit (50) is available to include an identification signal (bit b1) into said output signal, said identification signal indicating that said output signal comprises either said first digital audio signal or another audio signal. Further, a muting circuit (24) is present for muting the first digital audio signal supplied by the output circuit (50) in response to an occurrence of said selection signal for selecting said second audio signal. Said muting circuit maintains said output circuit (50) in a muted situation from said moment of occurrence (t0) of said selection signal until a certain time interval (t2-t1) after the corresponding change in said identification signal.

摘要： An audio bitstream is read from a digital video disc DVD for transfer, subsequent to parsing thereof, via an IEC 958 protocolled interface, for use in a multi-channel audio reproduction apparatus. For each respective audio channel MPEG audio samples are packaged recurrently in burst payloads, and these burst payloads are packaged as user data in IEC958 format frames. Pause bursts are used for signalling absence of audio for all associated channels with, each pause burst representing such audio absence during a perceptibly acceptable time interval only.
