Title:
METHOD FOR PROCESSING A PLURALITY OF VIDEOS
Document Type and Number:
Japanese Patent JP2005094755
Kind Code:
A
Abstract:
To provide a method for processing a plurality of videos, which minimizes a combined distortion and satisfies a combined frame rate constraint, for all videos.
Intra-, or inter-compressed frames of each compressed video are acquired at a fixed sampling rate. Joint analysis is applied concurrently and in parallel to the compressed videos to determine a variable and non-uniform temporal sampling rate for each compressed video so that a combined distortion is minimized and a combined frame rate constraint is satisfied. Each compressed video is then sampled at an associated variable and non-uniform temporal sampling rate to produce output compressed videos having variable temporal resolutions.
