摘要： Device for splitting an interlaced television frame into a vertical low-frequency spatial signal and a vertical high-frequency motion auxiliary signal. In a forward play mode the two signals are added together. In a reverse play mode, in which the frames are supplied in the reverse order, the motion auxiliary signal is subtracted from the spatial signal.

摘要： Device for splitting a digital interlaced television signal into components in which interlaced frames are applied to a vertical low-pass filter (6). To prevent motion artefacts in the spatial signal thus obtained, the interlaced frame is also applied to a vertical high-pass filter (8). This vertical high-pass filter supplies a motion auxiliary signal which may have a small vertical bandwidth. When combining the spatial signal and the motion auxiliary signal, noticeable motion artefacts do not occur in the interlaced frame. The device may be used for deriving a standard television signal from a high-definition television (HDTV) signal and for compatible transmission of HDTV signals.

摘要： A method of transmitting timing critical data via an asynchronous channel without changing any datum to be transmitted. The timing critical data can be an MPEG transport stream. The asynchronous channel can be a computer or telephone network, a digital storage media such as a digital VCR, or a digital interface. The method involves tagging each transmission unit of the data stream, before inputting to the channel, with timing information, and using the timing information at the output end of the channel to recreate the proper data timing, Various schemes are described for packing the timing information tags with each or a plurality of transmission units.

摘要： A device comprising an MPEG encoder (2) is provided with a preanalyser (8) which encodes each picture with a fixed step size (Q.sub.2). The preanalyser is coupled to a computing circuit (9) which computes, for each type of (I, P, B) picture, a target value (T) for the number of bits for encoding said picture, as well as a suitable distribution of the target value among the macroblocks of the picture. A proportionally integrating control circuit (7) controls the quantization step size (Q.sub.1). Since the PI control circuit does not introduce any residual errors, the desired number of bits per picture or per group of pictures is achieved within narrow limits. The output signal is eminently suitable for recording and subsequent editing.

摘要： A decoder for data encoded in a form combining a prefix which is a previously coded sub-string and a next data element in the data stream. The decoder includes memories for storing code words and data separately. Upon receipt of a code word the decoder stores the previously received code word, applies the newly received word to the code word memory to obtain the location of the last data element which is part of the data represented by the newly received code word, and another code word associated with the prefix. Upon completion of decoding the latest code word, the first data element of the decoded word is appended to the next previously received code word, and the combination is stored as the equivalent of a code word which is next after the highest code word already received. At least one memory is shared for use during encoding and decoding.
