Where does the EPG come from?
Is it incorporated into the output stream through PID's some how or is
it read from one of the other devices under adapter0?
Are there simple command line tools to read it or do you have to write a
custom program to interpret it somehow?
Could someone please point me in the right direction to get started? If
no tools exist, perhaps links to either api or lib docs/samples?
Much appreciated.
Chris.
Hello Chris,
The ATSC EPG is sent via the ATSC PSIP protocol. I do not know of any
tools currently available to extract the information. MeTV has a
working implementation (with some bugs I have seen), and I was looking
at getting it to work in Kaffeine at some point.
The spec is freely available here:
http://www.atsc.org/standards/a_65cr1_with_amend_1.pdf
Chris,
You'd expect to be able to get 3-4 days of advanced data to populate a guide
with, in reality you can often get as little a six hours and that's it. The
mandatory side of the spec is weak in this area. six hours is fine for Now /
Next but of little use for anything else.
Depending on your needs, your mileage may vary.
Regards,
- Steve
