摘要： A method and apparatus (100) for handling a layered digital video stream, comprising a base layer stream and an enhancement layer stream for providing HDTV, is disclosed. Either of the base layer stream or the enhancement layer stream is stored on a hard disc (101), and the other is stored on an optical disc by means of an optical disc drive (102). The streams are handled separately until they are utilized for providing HDTV. When the layered video stream is to be played back with HDTV quality, the base layer stream and the enhancement layer stream are synchronized by means of a synchronizer (106) for referring to the same frame. The synchronized streams are then decoded by means of a base decoder (105a) and an enhancement decoder (105b), which outputs decoded streams that are combined by an adder 112.

摘要： The invention relates to a system for processing video signals, the system comprising a receiver (100) arranged to receive video signals, at least one video frame of which comprises at least one area corresponding to a respective one of a plurality of broadcast data sources. The system comprises a processor (150) arranged to process said video frames to extract at least a part of said area from at least one of said video frames. The frame (200) of a mosaic video signal may comprise one or more small pictures (210) and each of them may render a miniature version of a television program. A detection of edges and a detection of lines can be performed for extracting said area (210) or sub-area (240) from the frame. The television channel, from which the extracted area or sub-area was received or with which it is associated, can be identified. The user is enabled to specify a representation of the extracted area or sub-area on a display screen.
