摘要： A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.

摘要： The availability of television channels today may easily be overwhelming for a user and the use of conventional linear zapping when a user switches sequentially between channels arranged in a list as a method of finding interesting content becomes still more inefficient. Thus, a method of automatically determining a channel content for multi-media, audio, and video channels distributed to or acquired by an electronic device is provided, the method comprises the steps of collecting channel data, analyzing the data using statistical methods to determine a channel content, and categorizing the channels into predetermined clusters depending on the channel content. The determination may be made dynamically so that the clusters reflect the specific day and/or time of the day at which the electronic device is used. Also a system for providing such a method is provided.
