   In my mind, there are a few basic requirements that would solve the
   problems of content authors for referring to a/v programming:

    - It should be simple to write a URL that says: "tune into this channel"

Yes

    - And a little bit harder to write a URL that says: "tune into this program"

Yes.  Or even the same degree of difficulty.

    - And it shouldn't matter if I'm watching it on cable, terrestrial or via
   satellite.

Yes!

   To do this, some kind of authority or database will be needed to resolve
   tuning parameters from channel & program identifiers, just like DNS is
   needed to resolve IP addresses from domain and host names.  Electronic
   Program Guides (EPGs) are one way to do this, but a more centralized system
   (or a hybrid) may also be appropriate.

Well, (an ATSC) box already has PSIP + EPG + ... data to work from, so
we just tell it how to do the transformation.

Cable, satellite, etc. may use different data, but they can do the same job.
