Apparatus and method for adjusting the cognitive complexity of an audiovisual content to a viewer attention level

摘要

To allow viewer to adapt audiovisual content to their attention level, the audiovisual signal processing arrangement (104, 106), comprising an audiovisual signal processing unit (104) arranged to receive from a control unit (106) at least one complexity setting value (S_Inf-c) specifying a complexity of information in an audiovisual signal, the audiovisual signal processing unit (104) being arranged to process an inputted audiovisual signal S(A, V) to decrease or increase its information complexity as determined by the complexity setting value (S_Inf-c), wherein the audiovisual signal processing unit (104) is arranged to process at least an audio component (A) of the audiovisual signal S(A, V).

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 configured
to 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.
