RATE DISTORTION OPTIMIZATION FOR INTER MODE GENERATION FOR ERROR RESILIENT VIDEO CODING

摘要

Optimal selection of an inter mode is provided for video data being encoded to achieve enhanced error resilience when the video data is decoded. End to end distortion cost from encoder to decoder for inter mode selection is determined based on residue energy and quantization error. Using the distortion cost function based on residue energy and quantization error, and an optimal Lagrangian parameter, the optimal inter mode is selected for use during encoding for maximum error resilience. The optimal Lagrangian parameter can be set to be proportional to an error-free Lagrangian parameter with a scale factor determined by packet loss rate.
