Television signal encoding.

摘要

An arrangement for encoding a television signal including a video signal, comprising means for producing an encoded television signal in accordance with a number of possible processing operations (5, 23; 9, 31; 13, 39) on the video signal, each processing operation providing a different distribution of spatial and/or temporal resolution, means (17) for obtaining a provisional selection for one processing operation on the video signal from the number of possible processing operations and for controlling (56) 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 means (45) for selecting one processing operation on the video signal from the number of possible processing operations on the basis of the consistent selection.
