Video system and method for automatic size and position adjustment according to the incoming stream

摘要

We describe and claim a video system and method for automatic size and position adjustment according to the incoming stream. A detection module detects a size and a position of video including an aspect ratio of video on at least one channel of at least one video input source. An execution module adjusts a scale mode responsive to the detection of the size and position or aspect ratio of the video. Once the aspect ratio has been detected and the scale mode adjusted responsive to the detection, video is provided to the display of a display device. The detection and execution modules crop unintentional vertical blanking interval (VBI) lines from upconverted video signals. An on screen display includes a selection for active management that provides for automatic detection of size and position information, or a manual control mode for selection by the user.
