SYSTEM AND METHOD FOR SCALING A VIDEO SIGNAL

摘要

A method is disclosed for determining scaling variables for video comprising the steps of: identifying an image within the video which has a predetermined size and shape when scaled properly; and adjusting the scaling variables for the video until the image matches the predetermined size and shape. Also disclosed is a system for determining scaling variables for video comprising: a database for storing one or more images; and a pattern comparator for comparing the images with images in a scaled video, and selecting particular scaling variables responsive to matching one of the images with an image included in the scaled video. Also disclosed is a system for scaling a video for wide screen television using proper horizontal and vertical scaling variables comprising: video identification means for determining an encoding type used to encode said video; scaling variable selection means for selecting the ideal horizontal and vertical scaling variables based on said encoding type; and scaling means for scaling the video by an amount specified by the horizontal and vertical scaling variables to produce scaled video.
