What is color stream on my tv?

Question

It looks like my tv has HD ports, there are extra blue, green, and red ports on there. And when I change the source it has an extra one called color stream. I'm wondering what this is, it's an older tv, maybe 5 years, it has a convex screen, which they hardly ever make anymore. So it has these ports and I tried to get my 360 to work on them. (also there is an extra composite ports next to th ones that look like hd but have no purpose, so I'm thinking thats audio) So I turn on the 360 set it to hd then go through the sources, once I get to color stream I can here it but the screen is just fuzzy with red blue and yellow and I get nothing on screen.

So what is color stream?

Answer 1

Just because your TV has component connectors doesn't mean it is HD.

Some SD TV's were produced with these inputs because they are a better way to connect to DVD players.

Color Stream was a proprietary Toshiba version of Component.

You're not getting a picture because you need to set your 360 to SD, not HD.

Answer 2

This was a Toshiba exclusive developed for DVD players to improve picture quality since the native format of DVD is component video. Y is video, Cb is color stream blue and Cr is color stream red.

These days we simply call this 480I.
