Submission + - TRS-80 Color Computer Digital Video Player (youtube.com)

An anonymous reader writes: This is a demonstration of version 2 of my digital video player for the Tandy Color Computer 3. Version 1 just never performed as well as I liked, so I revised it in preparation for this year's CoCoFEST! on May 21-22 2011 in Elgin, IL. See http://www.glensideccc.com/ for event details — I'll be there with a live demonstration for those interested in seeing it in person. I hope you will be as pleased with the revised performance as I am!

The video playback shown is 128x192 in 16-colors. The video is updated 60 times per second, although obviously not every update covers an entire frame. The audio playback is at 11040HZ. Audio samples are 8-bits each, although the stock CoCo3 audio DAC is only 6-bits. Each minute of video requires roughly 2-2.5MB of storage.

It is masked but always present. I don't know who built to it. It came before the first kernel.
