Picture Quality/Channels per Transponder

[zippyfrog]

I was thinking about this, but have never observed it so I don't know if it is true or not. I know the more channels that each transponder has, the worst the picture quality gets as there is only "x" number of Mbits per transponder, and those Mbits have to be divided between each channel. Is the amount of bandwidth per channel set, or does it change based off of what is happening on the channel? Basically, if there is a lot of movement on one channel and very little movement on another, if I were to take a snapshot of how much data each channel was using, would the one with more movement have more Mbits with it than the one that didn't? I was thinking about this during a Cubs game that was an afternoon game on CSN Chicago and it was the only game going on. I thought that maybe the picture quality would be a lot better than normal because there were no other games going on, so those other slots in the HD RSN transponders weren't being used, so then more bits would be put to the only game that was on, thus better picture quality. But the picture quality wasn't better than normal. So it got me thinking that the amount of bits per channel is set. But I was wondering if anyone had a definite answer to this.

The bandwidth is dynamically shared between the channels. If one channel has a still scene and the other has lots of movement, the bits that the still scene aren't using will be given to the channel that needs more bits for the fast scene.

Also keep in mind that the channel is only as good as the source. Perhaps the RSN itself only uses a certain amount of Mbps regardless of how much bandwidth Dish has. You can use ( SatelliteGuys.US_TheList - TheList ) to see which channels share transponders.
