VIDEO ENCODING OPTIMIZATION WITH EXTENDED SPACES

摘要

Embodiments of the present invention may provide a video coder. The video coder may include an encoder to perform coding operations on a video signal in a first format to generate coded video data, and a decoder to decode the coded video data. The video coder may also include an inverse format converter to convert the decoded video data to second format that is different than the first format and an estimator to generate a distortion metric using the decoded video data in the second format and the video signal in the second format. The encoder may adjust the coding operations based on the distortion metric.

1. A method, comprising:
performing coding operations on an in-process formatted input signal to generate coded video data; decoding the coded video data; converting the decoded video data to another format than the in-process format; estimating coding factors using the another formatted decoded video data and the input signal in the another format; based on the estimated factors, adjusting the coding operations; and outputting the coded video data.
