ABSTRACT:
An arrangement for encoding a television signal including a video signal, comprising a circuit for producing an encoded television signal in accordance with a number of possible processing operations on the video signal, each processing operation providing a different distribution of spatial and/or temporal resolution, a circuit for obtaining a provisional selection for one processing operation on the video signal from the number of possible processing operations and for controlling a spatial and/or temporal consistency of said provisional selection for a processing operation on a portion of a picture of the video signal compared with selections for processing operations on spatially and/or temporally adjacent portions, to obtain a consistent selection, said consistency control comprising a spatial/temporal consistency control and a spatial consistency control, to obtain a television signal encoding with an improved consistency control, and a circuit for selecting one processing operation on the video signal from the number of possible processing operations on the basis of the consistent selection.
