That was my thought too. The Linux machine (okay, it doesn't have to be
Linux really) could capture 1-2 frames per second and display all the
information on its own video out, which would be piped back into the TV.
Simple solution: recognize the solid horizontal bars that separate each
line of info in the scrolling display. Use these lines to pick apart the
display into a set of images, one for each channel's text description.
Stack these images on top of each other on the display, updating them
as you read new ones from the capture card.
Better solution: OCR the text out of the descriptions on the screen
(this should be easy, since it's always the same, computer-generated font
in the first place). Now that you hve textual information, you can
display it in your own choice of font and layout, scroll around in it,
search for keywords or favorite shows, etc.
Complex solution: As above, but publish the information to the Web
as an RDF or other sort of feed. This way everyone in your area can
benefit. Open-source the software so that a single Linux box in
each region can provide up-to-date program information to anyone
who wants it. Link this into the open-source PVR projects. Get sued
by the advertising industry; sell your computers and 'net connection
to pay the legal fees. Return to waiting for the program information
to slowly crawl up the screen.
(Oops, this is sci.*electronics*, isn't it? I guess I need to
come up with a solution that involves a 555 and a 741 opamp somehow...)
