Re: [linux-dvb] EPG (Electronic Program Guide) Tools
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.

EPG (Electronic Program Guide) Tools
Hi: I've installed an HVR-1600 TV card in a Debian system to receive ATSC digital broadcasts here in Canada. Everything works great. scan /usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB channels.conf finds a complete list of broadcasters. azap -c channels.conf -r channel-name tunes in the stations and displays signal strength info. cp /dev/dvb/adapter0/dvr0 xx.mpg captures the output stream which can be played by mplayer. What I'm missing is information about the Electronic Program Guide (EPG). There doesn't seem to be much info on linuxtv.org on how to read it. Googling hasn't produced meaningful clues. 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?

Separate apps. with dvbstreamer you have to cycle the channels with a script to fill the data for each channel. Later Jonathan Devin -- Devin J.
