ABSTRACT:
An audiovisual system receives audiovisual data and includes a system controller and a storage device to store at least a portion of the audiovisual data for later playback. The audiovisual system further includes a marking module to create metadata in response to a control input for marking the program segments. The metadata includes the information regarding the program segments of the stored portion of the audiovisual data. The audiovisual system further includes a display generator to generate a mosaic representation of the program segments. The audiovisual system further includes a program selector to select a program segment in response to a user input. The selected program segment is selected based on the information of the metadata, whereby the audiovisual system selectively plays back selected program segments of the stored portion of the audiovisual data starting from selected program locations, thereby enabling a user to jump to and play back selected program segments.
