Abstract
A method and apparatus for producing video signals comprises a receiver for receiving a video signal, a video pipeline for post-processing the received video signal, the video pipeline producing a post-processed video signal, and a video output module for converting the post-processed video signal, the video output module producing a formatted video signal. The video output module may further comprise an ancillary data injector, the injector inserting ancillary data into the post-processed video signal. Also, the video output system may further comprise a generator locking device or the video input module may include a generator locking device.

A system for producing video signals, the system being communicatively coupled by electrical communication paths to a video graphics processor, a video signal input system, and a storage medium for storing data in electrical form, the system comprising:
- means for receiving a video signal;
- means for post-processing the received video signal, the post-processing means producing a post-processed video signal, wherein the post-processing means includes functionality for performing the following functions:
- region of interest selection;
- frame rate matching;
- spatial adaptation;
- changing the sample rate of the video signal being post processed;
- gamma removal;
- gamma insertion;
- color space conversion;
- changing frames of video data into interleaved fields of video data;
- and
- addressing on a frame by frame basis the video signal being post processed;
- and
- means for converting the post-processed video signal, the converting means producing a formatted video signal wherein:
- the converting means includes:
- a means for inserting ancillary data into the post-processed video signal;
- and
