摘要： A system for processing audio-video data to produce metadata, has an input for receiving audio video data. A characteristic extraction unit is arranged to extract n multiple distinct characteristics from the received audio-video data. A data comparison unit is arranged to compare the n multiple distinct characteristics with data extracted from example audio-video data by comparing in n dimensional space to produce a value for each of f features of the audio-video data where f

摘要： A system for controlling the presentation of audio-video programmes has an input for receiving audio-video programmes. A data comparison unit is arranged to produce at intervals throughout the programme a value for each of f features of the audio-video and then to derive from the features a metadata value, the metadata value having M dimensions, the number of dimensions being smaller than the number of features. A threshold is applied to the metadata value to determine points of interest within the audio- video programmes and a controller is arranged to control retrieval and playback of the programmes using the interesting points.
