摘要： Video signal information derived from a high definition source is conveyed via two channels. A first channel conveys relatively low spatial resolution, high temporal resolution video information compatible with a standard television receiver. An auxiliary second channel conveys relatively high spatial resolution, low temporal resolution video information. A high definition television receiver reconstructs original high definition information from the first and second channel information.

摘要： A method for the transmission and/or recording and playback of digital data wherein the data are converted in sections to digital signals whose word length is a function of the information density of the data sections which reduces the susceptibility of the data to interference. In accordance with the method the digital signals obtained in sections are initially assigned to blocks having a constant word length, whereupon the blocks whose data sections have a smaller word length than the word length given by the blocks are filled with portions of data sections having a word length greater than the word length given by the blocks and finally the data sections are recombined from the blocks in their original word lengths.

摘要： A set top box can be connected to a DVD Streamer via an IEEE1394 interface which contains means to timestamp data and to strip off these timestamps again, using them for timing regeneration. The DVD stream also must regenerate the timing of data packets as it was upon recording, when these packets are played back. The streamer could also use its own timestamps and strip them off again when replaying. So, in total, there is an in-series connection between two time stamping and time regeneration mechanism which introduces jitter accumulation.

摘要： A cassette for use with a recording apparatus comprises: a housing for a recording medium, the housing having a first surface and side walls, the recording medium being accessible through one of the side walls; at least a part of a chip card affixed to the housing, forming a second surface of the housing and closing the cassette, the chip card part having a memory formed integrally therewith and externally accessible contacts; and, the contacts of the chip card being positioned on the second surface to be engageable by corresponding contacts in the recording apparatus when the cassette is inserted therein. One of the side walls has an access door for the recording medium and the second surface forms an upper wall of the housing as defined by the access door. The part of the chip card forming the second surface of the housing has a marking position at which light transmissivity can be controlled. The marking position can be rendered non transmissive to light to prevent recording.

摘要： In bitstream recording presentation data is organized into Video Object Units. These have a variable size but have also a variable duration. To allow access to any Video Object Unit in the bitstream a housekeeping address table is used which is based on pieces of the bitstream of constant size per piece. The address table additionally contains for each of these pieces a specific delta duration which indicates the time difference between the arrival time of the first packet of a piece and the arrival time of the packet following immediately the last packet of that piece. The computation of the target VOBU address includes the following steps: accumulate the delta durations until the given time value is most closely reached towards the target VOBU; the running index of this table entry multiplied by the constant piece size directly results in the address value to be accessed.

摘要： In a system for generating a compatible television signal with a "letterbox" display format, groups of vertically arranged picture elements (pels) are subjected to vertical DCT transformation producing eight DCT coefficients. Intermediate sixth and seventh coefficients are placed in the letterbox bar regions. The remaining six coefficients, namely the first through fifth coefficients and the highest frequency eighth coefficient, are inverse DCT transformed and processed with the main image information. A standard aspect ratio receiver displays a letterbox image using only the remaining six coefficients. A wide aspect ratio receiver uses the six remaining coefficients with the two coefficients from the bar regions, after inverse DCT, to produce a full resolution wide aspect ratio image.

摘要： A method of signal processing batch-bulk coded digital signals which are segmented into variable-length words and the variable-length words are allocated to constant-length blocks. The constant-length blocks which receive a variable-length word having a word length which is shorter than a predetermined word length are filled up with portions of variable-length words having a word length longer than the predetermined word length. Several successive constant-length blocks are combined into superblocks, and one address word which identifies the superblock location is added at one end of each superblock. The sum of the variable-length words within each superblock is smaller than, or equal to, the sum of the constant-length blocks within the superblock.
