摘要： A data processing system comprises a data compression decoder arranged in operation to decode first and second encoded data to produce first and second uncompressed data representative of first and second source data from which the first and second encoded data were produced in accordance with a compression encoding algorithm respectively. The data compression decoder also produces first and second compression parameter data representative of encoding decisions made by the compression encoding algorithm when the first and second source data was compression encoded. The data processing system also comprises a data compression encoder which is arranged in operation to compression encode the uncompressed data in accordance with the compression encoding algorithm using the first and/or the second compression parameter data, and a data communications apparatus coupled to the data compression decoder and the data compression encoder and arranged in operation to communicate the first and/or the second uncompressed data and the first and/or the second parameter data, wherein the first and second uncompressed data and the first and/or the second parameter data are separately communicated via a common communications channel provided by the data communications apparatus. The compression encoding algorithm may be an MPEG-type algorithm, such as MPEG-2. The data processing system provides an advantageous alternative to the MOLE (TM).

摘要： A digital video tape recording/playback system having a plurality of recording heads (A, B, C, D) on a rotating head mechanism 94 for recording slanting tracks 108 which extend diagonally across a tape 82 provides processing of video signals in a plurality of data processing channels with selective connection of the data processing channels to the recording heads such that data from a plurality of data processing channels are stored in respective portions of a slanting track (A+/A-; B+/B-; C+/C-; D+/D-). The data in each data processing channel and recorded in each track portion is sampled with a substantially even distribution over a field of video signals to provide for effective concealment of recording/playback errors. Preferably, two data processing channels are recorded on each track, the respective portions being located in upper and lower portions of the tape, respectively.

摘要： A video data compression system is described utilising frequency separation and quantization. The video data is separated into primary frequency components (components 4, 5, 6) and secondary frequency components (components 0, 1, 2, 3). The primary frequency components undergo fewer frequency separating stages (N > M) than the secondary frequency components. The quantization step width (Q₁, Q₂) applied to the differing primary and secondary components is varied in dependence upon the relative human visual responsiveness (R(f s )) to the spatial frequency (f s ) represented by that component. In addition, those frequency components that have undergone fewer frequency separating stages are subject to a larger quantization step width than the other frequency components since the fewer frequency combination stages such frequency components will subsequently undergo has the result that the image degradation introduced by quantization is less noticeable. The system also includes entropy encoding (42) using selectable complementary encoding and decoding tables. The system is particularly applicable to recording and reproducing apparatus.

摘要： A digital signal comprises. data blocks, each data block including a header containing data relating to the block and a plurality of slots. Each slot has a slot header relating to the slot and a data packet. The data packets contain successive parts of information from a source. A first slot contains a first packet containing a first part of the said information from the source also contains a reference time. The or each subsequent slot contains a subsequent packet of the information from the said source also timing information defining the timing of that packet relative to the reference time. An encoder which encodes such a signal is provided. The corresponding decoder is enabled to correctly output the packets to allow correct decoding. Absolute delay of the packets has no effect on decoding. Jitter ( i.e. variation in the timing of the packets relative to each other) may corrupt the decoding. The decoder compares the timing information of each packet with an internal clock set by the reference time of the first packet and outputs the packets when the clock time equals the packet time thus at least reducing the jitter. The data blocks may be SDTI fixed length blocks and in a transmission system the packets are MPEG 2 TS packets, which are transmitted via an SDTI system. The data blocks may be SDTI variable length blocks and the packets may be MPEG2 TS packets, ATM cells or Internet Protocol packets.
