V+ : Analysing sound / vision on channels

[smallclone]

Briefly:

Is there anyway to find out exactly what definition the sound and vision of a channel is?

E.g: Channel 999 - 640 × 480 p and dolby digital surround sound?

Thanks

Not unless you've either got very deep pockets or friends in the right places.

But there are some general rules
- All SD channels are MPEG-2 video with stereo MPEG-1 Layer II audio. The vertical resolution is always 576i.
- All HD channels are MPEG-2 video. The vertical resolution is always 1080i.
- Audio description is always MPEG-1 Layer II, but could be mono or stereo.
- All radio channels are MPEG-1 Layer II audio, usually stereo. (Last time I checked, BBC World Service was mono)

Any particular reason?

Just expectancy levels really.

I'd like to know if my surround sound is actually supposed to work or not.

There's no easy answer to that. It varies from programme to programme.
