Tom;

They've been required to pass along program-related PSIP for years and
years.  

Many do.  To do so effectively, they need to create CVCT (cable virtual
channel table) entries for each over the air virtual channel.  Many encoders
do this,  One cable engineering executive told me during the summer that
Harmonic encoders do this particularly well, and almost automatically.

You need the CVCT (entry) because EPG events need a binding context, called
the source_id, to link to, then the CVCT entry needs to be bound to the
program_number field in the PAT and in the header of the Program Map Table.

To the extent that cable operators "do their own thing" they have not been
complying with FCC rules.  Their EPGs are okay for navigating, but since
they get their information from listing services, they are about as accurate
as newspaper listings.

Want an example?  Many people missed the last finale section of "American
Idol" because the winner wasn't announced until after the scheduled end of
the program.  No basketball, football or baseball game can be scheduled
accurately in advance.  In some cases, networks don't know what football
game will be sent to a particular station until a second before the switch
is made.

John -

What is the status of cable operators using or passing along PSIP info.

It seems there was some discussion about this and they were not yet 
required to do anything with PSIP but there was a possibility of it 
being used.  Is there?

Or are the cable operators going to just continue to do their own thing 
with only their own info?

- Tom
