Brief description of the transmission of signals of the difference in color television, sender and receiver of signals of the television in colors comprising a device for implementing this method and system of transmission of a color television signals, including a sender and / or a receiver of this type.

摘要

Colour television signal receiver comprising a decoding device receiving from the transmission channel, in sequential form and line by line, components of type U or of type V alternately and which consists of the following elements for processing these components: a. A demultiplexing circuit 400 routing towards one or the other of two processing paths the components of type U and of type V arriving sequentially; b. In the path for processing the components of type U: 1. A first selection circuit 520, 2. An interpolation circuit 530, 3. A second selection circuit 540; c. In the path for processing the components of type V, similar circuits 610 to 640; The said second selection circuits 540 and 640 being intended to allow the reception of components of type U and V either from a frame said to be reconstructed from the transmitted frames, or from a frame said to be interpolated from the reconstructed frame.
