Abstract

Future consumer terminals will be more and more based on programmable platforms instead of only dedicated hardware. Novel scalable video algorithm (SVA) software modules trade off resource usage against quality of the output signal. SVAs together with a strategy manager and a quality-of-service resource manager (QoS-RM) aim for flexible, robust, and cost-effective media processing in software on programmable architectures. We developed some SVAs including MPEG-2 decoding and image enhancement algorithms and the basic QoS control software to illustrate the power of the overall system. The resource limited hardware is a currently available DSP board with a single dedicated media processor1. The system supports two inputs and several modes for main and picture-in-picture (PiP) window applications, along with background recording.
