Abstract
An apparatus processes a video stream signal. The video stream signal represents a succession of frames, comprising a plurality of dependent frames that each provide for prediction of visual content using selectable ones of a preceding and following anchor frame that precede and follow the plurality of frames respectively. When a shortage of transmission bandwidth occurs, the apparatus generates a processed version of the video stream signal wherein a bit-rate alteration is performed starting from one of the dependent frames before an end of said plurality. Said alteration is executed by substituting a standard prediction from the following anchor frame at least for data in the video stream signal that encodes a region in said one of the dependent frames. The bit rate alteration is accompanied by a switch to a mode in which the processing circuit substitutes a standard prediction from the following anchor frame in all following dependent frames that follow said one of the dependent frames until the following anchor frame, for data in the video stream signal that encodes the region in said following dependent frames. In an embodiment interlacing is killed for the replaced regions.
