Apparatus and method for adjusting the cognitive complexity of an audiovisual content to a viewer attention level
First Claim
1. An audiovisual signal processing apparatus, the apparatus comprising:
- a receiver for receiving audiovisual signals, each signal having one or more components, wherein the one or more components include a time unit;
a processor configuredto assign a value of complexity to the received audiovisual signals based on complexity of the respective one or more components, andto playback the received audiovisual signals in accordance with a value of viewer desired complexity by increasing or decreasing complexity of the playback of the one or more components by changing a number of words rendered in the time unit,wherein the one or more components include an audio having a plurality of temporal parts and voice data, and the processor increasing or decreasing complexity includes changing a volume of certain of the temporal parts of the audio component and changing a spectral characteristic of the voice data component.
