Re: So Charter is going to go to metered service huh? Ok, YES all HD is compressed. When you get a HD DVD(whatever format) it is also compressed, that is how digital video is moved (99%anyway). As you pointed out it is the rate it is compressed. The OTA basically sends the signal out at the same compression that they receive it. Cable/sat crunch it down(reduce quality) further to minimize their bandwidth usage. OTA does not care about the amount of bandwidth it uses. They do not have to reduce the quality of the video/audio so that it will "fit in the box" like cable/sat does. |

Not sure what cable or sat HD streams are.
