A better implementation probably requires deeper changes within the channel structures. (and should IMHO be a change to a DVB header independent structure.) Since I don't use either of the new APIs I'll leave these changes to others though.

[vdr] FW: [ANNOUNCE] DVB API improvements
Hello all (and especially Klaus): It's official, the people from V4L have voted for the usage of the S2API proposal to be the future for new DVB API improvements (see the official announcement at the bottom) within the V4L tree. Currently S2API is in a real speed-train and new devices are added very rapidly. Only the devices currently in Multiproto and written by Manu Abraham are not yet ported. Also people are allready busy with patches for Kaffeine (allready done) and MythTV (not seen yet, but it's WIP according to a post on the linux-dvb mailinglist). So, this should mean that VDR 1.7.x should focus on S2API because of the obvious reasons. Has anybody started on a patch of somekind to include S2API in VDR 1.7.0 or 1.7.1? Mainly I was thinking of doing it myself (I have a Hauppauge WinTV-NOVA-HD-S2 which is allready supported in S2API) in the hope to have it working in the next weekend. But if it's allready done or in progress, then I would like to use my time for something else ;) Regards, Niels Wagenaar -Original message- From: Mauro Carvalho Chehab <[EMAIL PROTECTED]> Sent: Tue 23-09-2008 23:19 To: DVB ML <[EMAIL PROTECTED]>; Subject: [linux-dvb] [ANNOUNCE] DVB API improvements > After years of discussions, several patch series and two different proposed > approaches, LinuxTV developers finally decided that S2API is the better > technical proposal and should be accepted as the way to allow supporting newer > DTV standards, starting with DVB-S2. > > As previously announced at > http://linuxtv.org/news.php?entry=2008-09-19.mchehab, > a representative group of active developers at LinuxTV community attended the > first V4L/DVB Summit, that started with the V4L/DVB miniconf at Linux > Plumbers/2008.
