Abstract
Video decoder adapted for decoding video based on decoder parameters selected from variable decoder parameters, the decoder comprising an estimator adapted to estimate user viewing experience based on sensor data and comprising a constraint analyzer adapted to analyze constraints when using the decoder parameters, the video decoder further comprising a selector adapted to select said decoder parameters from the variable decoder parameters, wherein the selector is coupled to the estimator and the constraint analyzer.

Video decoder adapted for decoding video based on decoder parameters selected from variable decoder parameters, the decoder comprising an estimator adapted to estimate user viewing experience based on sensor data and comprising a constraint analyzer adapted to analyze constraints when using the decoder parameters, the video decoder further comprising a selector adapted to select said decoder parameters from the variable decoder parameters, wherein the selector is coupled to the estimator and the constraint analyzer.
Video decoder according to any one of the previous claims, wherein the selector is adapted to translate the selected decoder parameters into codec parameters, and wherein the video decoder further comprises a communication module for sending the codec parameters to a video encoder.
Video decoder according to any one of the previous claims, wherein the constraints comprise one or multiple of computational requirements, memory footprint, battery use and bandwidth use.
Video decoder according to any one of the previous claims, wherein the sensor data is adapted to measure environmental parameters and wherein the user viewing experience is estimated based on predetermined correlation between the environmental parameters and the user viewing experience.
Video encoder adapted for encoding video based on codec parameters, wherein the video encoder comprises a communication module for receiving the codec parameters from a video decoder according to any one of the previous claims.
Method for decoding video based on decoder parameters, wherein the method comprises:
- estimating user viewing experience based on sensor data;
