The concept of "currency" may need some explanation - "the channel carrying 
the signal in which the URL is embedded" is what we're looking for, I think.

No.
This URI is so that the user can continue to watch whatever program they
were watching.
We use it as a small window in a toobar area, for example.
If the box has only one decoder in the digital case or tuner in the analog
case then it's whatever it was set to. For multiple decoders it is not so
obvious: either the last channel selected by or for the user, or the channel
the primary tuner is set to.

I'd like to lose this too; it's an americanism, and confuses the issues, I 
think. Is there a station with callsign FIRM?

Short names that the channel by which the channel is usually known are
useful and easy to understand. Most countries have at least an informal
scheme for TV channel names. 
These names are typically bound locally, for example for EPG entries.
Maybe we should prefix the short name with a country code (e.g tv: uk/BBC1)

Problem with this is where one organisation (e.g. BBC at www.bbc.co.uk)
originates several channels (BBC1 BBC2, BBCChoice, BBCKnowledge,BBCNews24,
BBCParliament etc).
