It will probably take a few weeks, as > there are some higher-priority things on my TODO right now. I'm starting this work now. First, I think the thing shouldn't be specific to TV, as radio-tuning is essentially the same (isn't it?). I think these are the functions that must be provided by libtuner, from an application's perspective: * provide list of available frequency-sets [loosely related to country, cable/antenna etc, like "norway/cable/telenor". I guess some naming scheme should be worked out.] * given a frequency-set, provide list of canonical frequency-names [like "S21", "E7", "E8" etc.] * given frequency-set and canonical freq-name, provide frequency [in Hz]. * given freq-set, provide list of programs/channels (what is the better term?) [like "BBC", "NBC" etc.] * given freq-set and program, provide frequency in Hz or canonical freq-name. * inverse of the above. In addition, there must be some means to add programs etc. I expect there will be some global database of different countrys frequency-sets [like /usr/local/share/tuner-freq-sets.rc] and some local config-file [like /etc/tuner.rc] with default freq-sets and local overrides. Please give your feedback on this overall design. -- Frode Vatvedt Fjeld To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
