Abstract
Future consumer terminals (TV sets, set-top boxes, displays) will increasingly be based on programmable platforms instead of only dedicated hardware. When the available resources are insufficient to deal with the worst-case requirements then resource overloads might lead to system instability and reduced output quality. For robust and cost-effective media processing on programmable platforms, dynamic resource management is required together with resource-quality scalable video algorithms. A way to prevent resource overloads is to stop processing when the assigned resources have been used. This may lead to drops and changes in quality. We propose to use shot-change information prior to the actual processing to predict difficult situations and react on them in a proper way. For a scalable motion estimator we show that, after a shot-change, generating motion vectors that indicate zero or close to zero motion prevents overloads, saves resources and can lead to a higher quality.
