DTT Multiplexies

I have what may be a silly question here, but since DSO last year here in the North West it has been bugging me.

- How many video feeds, text feeds and radio feeds can one multiplex hold?

Reasonably good amateur site that's regularly updated which should give you answers.

Thanks DVB, but is there anywhere that is a little less complicated.

Basically, a multiplex can hold as many services as the transmission provider wants. How much space each service occupies depends on the bitrate of each service. Each post-DSO multiplex can transmit 24mbps of data, with the exception of the HD mux which can transmit more (how much more I don't know). In pre-DSO areas, Muxes 1, B, C and D can carry 18mbps of data, with 2 and A the same as DSO areas.

Out of the multiplexes total capacity, audio is generally either 128kbps or 192kbps, and video is about 3mbps. On the site linked by DVB Cornwall you can see the exact bitrates for each service. The lower the broadcasters can push the bitrates, the more they can fit in.
