When a recording starts, the recording script needs to check for this dvbstreamer and kill it before the recording starts, else the recording will fail to initiate as the only tuner is being used. The catch is, you need to have this run in the background while you are not recording as it will use the only tuner on your card for getting the broadcasted EPG data. If you record frequently or rarely have local Internet access for syncing your computer's time, this might be the next best method, if not the best method for keeping your computer's time accurate. With a little grep or awk scripting and placing into /etc/init.d, could easily use atsc_epg EIT/ETT scheduling data for syncing your local computer's time.Īs you can see, my system is synced using a popular NTP client daemon and it's approximately 15 seconds slow when compared to the of the locally broadcasted EIT/ETT scheduling data. This one PBS frequency will broadcast all four PBS channel's EPG data along with printing each of the four channel numbers to stdout.) However, notice the atsc_epg command only needs a frequency and atsc_epg will tell you the channel number(s) the frequency will resolve to on stdout as well. Now automating this process to use $HOME/.mplayer/nf (dvbscan) data is a bit of a trick, especially if channels are updated. This will print a very nicely formated schedule to stdout!
More duplicated entries can be created to eleviate the need for typing ".1" for the first channel. I have already emailed the linux-media mailing list on to include a switch for writing the channel number to the file instead of the channel letter identification.įor the meantime, I've found a method of creating duplicate frequency entries, and then replacing the channel letter name field with the channel's number.
The remainder of the fields relate to the frequency.įor my area, the channel number reported by dvbscan on stdout is correct, but the channel lettered identification contains identical duplicates or is not well named. The first field of this file is the lettered name field, of which, you may likely see duplicate identical names and no channel numbers.

The channel naming scheme for over-the-air digital TV is likely not well thought out in your area. Replace "KUAC 1" with "9.1") Reason being, MPlayer has issues trying to use channel names containing spaces or other characters, and just using numbers makes playback using "mplayer dvb://9.1" easier. Within the w_scan output provided by the above, replace the channel call letters with their related channel numbers. You may also create the list of channels directly using w_scan, thus skipping over the need for an initial tuning file, see w_scans output formats.
To acquire your own initial tuning data for your area, use media-tv/w_scan. To get a list of channels from your digital TV USB or PCI tuning device, the generic dvbscan application from the package media-tv/linuxtv-dvb-apps can be used.ĭVBScan requires initial tuning data file to find your local frequencies, and already has been prepackaged with numerous generic initial tuning data files.
