High efficiency video coding for video with interlaced and progressive content using lookahead

摘要

A method for encoding a video signal with both interlaced and progressive content using lookahead is disclosed. The method may include steps (A) to (C). Step (A) may calculate a cost of being interlaced within each of a plurality of windows in the video signal. The video signal generally has a plurality of interlaced fields and a plurality of progressive frames. Step (B) may determine a plurality of points in the video signal. Step (C) may encode the video signal with switching between a field mode and a frame mode at one or more of the points based on the costs. The encoding may be a high efficiency video coding.

1. A method for encoding a video signal with both interlaced content and progressive content using lookahead, comprising the steps of:
(A) generating a plurality of transform coefficients by transforming a plurality of blocks in said video signal, wherein said video signal comprises a plurality of interlaced fields and a plurality of progressive frames; (B) calculating a cost of being interlaced within each of a plurality of windows in said video signal, wherein said cost is based on a sum of multiple high vertical frequency coefficients of said transform coefficients; (C) determining a plurality of points in said video signal; and (D) encoding said video signal with switching between a field mode and a frame mode at one or more of said points based on said costs, wherein said encoding comprises a high efficiency video coding.
