You will significantly enhance video encoder quality by incorporating external input/feedback from the system. Additionally, the robustness of the video codec will also be vastly improved. The video codec can use such information to react quickly and adapt to changing dynamics of the input video signal. This greatly enhances the end-user experience as the video encoder can prioritize the more important spatial and temporal parts of the video signal.

This application note presents features that have been incorporated in the TMS320DM365 H.264 codec, which makes use of external input/feedback from the system to improve the overall end-user video quality. Specifically, face information is obtained from the DM365 video processing front end (VPFE) and these regions are represented with higher fidelity. Scene change information is detected using a low-resolution encoder, which is used by a high-resolution encoder to encode the scene change frames as I-slices.
