channelid( <variable> )

Description

This sets the specified variable to the channel ID as broadcast in the TSDP packet.

Each channel is supposed to broadcast their identity, however a number (such as the BBC on digital satellite) either don't broadcast a TSDP packet or they broadcast a null identity (which is either &2020 or &0000).

Notes

I do not have IDs for the UK terrestrial channels. If you can help, please get in touch.

Here are the identities of some FTA channels from the SkyDigital platform (Astra 2 at 28.2°E and EuroBird at 28.5°E):

BBC One SouthNo ID
BBC Two EnglandNo IDVery reduced service, go to p199 for index.
Channel Four&3F8BOnly carries subtitling?
S4/C Digidol&2DE3Index is on p400.
Sky News&3F5FMostly 'betting' information.
EuroNews&0000Invalid identity.
Sky News UK/Eire (Cable) &3F9FA better Sky teletext service!
Travel Channel&8888 Doesn't sound like a real ID.
There are other teletext services available, but generally these are only for subtitling, such as ITV, E4/More4/Film4...

Here are the identities of some FTA channels from the Astra1 platform (Astra 1x at 19.2°E):
