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 () 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 () 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.

Method and apparatus for selection of content from a stream of data

A method of and system for detecting a cartoon in a video stream are provided. The system comprises a storage device for storing the encoded signal and a processor for processing low parameter information extracted from the encoded video signal. The information is extracted based on the predetermined characteristics of a typical cartoon. At least one value is computed based on the low parameter information and it is compared to the predetermined values for natural video. Based on the comparison the determination is made whether the video sequence contains a cartoon.
