Abstract: A controller for controlling the output of an audio-video feed has an input for receiving audio-video content and a vector engine arranged to produce a continuous metadata value of M dimensions at intervals from the audio-video content. The metadata value may indicate aspect of the video content such as rate, pace, tone or other such information. A low pass filter and hysteresis filter are then provided to filter the continuous metadata value to produce a binary output. The binary output is provided to a retrieval module arranged to control the audio-video content in dependence upon the binary output. In this way, automated segmentation of audio-video content may be reliably achieved.
