    • 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.
