    摘要: In a video processing system having an intra-field processing mode which allows a better luminance-chrominance separation, and an inter-field processing mode which allows a better performance in the presence of motion in the color signals, wherein a motion-dependent choice is made between these modes, chrominance-difference signals (Ud, Vd) are derived from chrominance signals (U, V), and a first linear combination of the chrominance-difference signals (Ud', Vd) is derived when the V chrominance-difference signal (Vd) exceeds the U chrominance-difference signal (Ud'), and a second linear combination of the chrominance-difference signals (Ud', Vd) is derived in the opposite case, to obtain a motion signal (M) for the motion-dependent choice.

    摘要: A transmission system includes a transmitter (10) and at least one receiver (14) configured to receive signals transmitted therefrom. Carousel-forming data file and directory objects are sent in cycles, with predetermined groups of file and directory objects being formed into respective modules at the transmitter, suitably according to MPEG-2 DSM-CC protocols. Each of the modules is transmitted as a whole, and the receiver is arranged to record received file data and directory objects under a predetermined grouping formulation, at elementary stream or module level.

    摘要: Device for coding and decoding an extended definition video (EDTV) signal. The EDTV signal is composed of a first series of picture lines with a compatible video signal and at least one second series of picture lines with a helper signal. The device for adding extra picture lines includes apparatus to the first and/or second series of picture lines. The extra picture lines may include a constant luminance signal, the reference. signal of PALplus picture line 623, or a duplicate of the most adjacent picture line from the PALplus signal.
