Abstract: 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.

Abstract: 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<n. A multi-dimensional metadata unit is arranged to receive the values for each feature and to produce a complex continuous metadata value of M dimensions for the audio-video data where M<f.

Abstract: A support device for an edematous scrotum is provided, which comprises a body portion adapted to be worn about a man's mid-section, a first connector for joining ends of the body portion together, and a plurality of second connectors. A receptacle is also provided and is adapted to receive and support an edematous scrotum and comprises a plurality of support members each adapted to couple with one of the plurality of second connectors to thereby provide comforting support to the scrotum.
