Rate/distortion optimization in multiple description video coding

作者：

Highlights：

• An analytical method for distortion minimization in video MDCs was developed.

• The core of our formulations is the mismatch of the side and central decoder outputs.

• For three values of PLR, the optimized MDC leads to a higher video quality.

• In high PLRs the best strategy is to duplicate the same stream into both descriptions.
