Audio-Video Content Control
First Claim
1. A controller for controlling the output of audio-video content, comprising:
- an input for receiving audio-video content;
vector engine arranged to receive the audio-video content and to produce a continuous metadata value of M dimensions, at intervals;
a low pass filter arranged to receive the continuous metadata value and to pass changes below a threshold;
a hysteresis filter arranged to receive the filtered complex continuous metadata value and to produce a binary output; and
a retrieval module arranged to receive the binary output and to assert a control signal to allow control of the audio-video content in dependence on the binary output.

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.

11. A method for controlling the output of audio-video content, comprising:
-
receiving audio-video content; producing, using a vector engine, a continuous metadata value of M dimensions, at intervals from the audio-video content; filtering, using a low pass filter arranged to receive the continuous metadata value and to pass changes below a threshold; filtering, using a hysteresis filter arranged to receive the filtered complex continuous metadata value and to produce a binary output; and asserting a control signal derived from the binary output to allow control of the audio-video content in dependence on the binary output. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
