I agree with Christoph. Is it that the input subsystem is better developed and seen as a leverage point for development and thus an "easier" place to get results earlier? If so, then one should definitely deal with transmitters early in the design, as that is where the most unknowns lie. With the end of analog TV, people will have STBs feeding analog only video cards. Being able to change the channel on the STB with an IR transmitter controlled by applications like MythTV is essential. And on some different notes: I generally don't understand the LIRC aversion I perceive in this thread (maybe I just have a skewed perception). Aside for a video card's default remote setup, the suggestions so far don't strike me as any simpler for the end user than LIRC -- maybe I'm just used to LIRC. LIRC already works for both transmit and receive and has existing support in applications such as MythTV and mplayer. I believe Jarod's intent is to have the LIRC components, that need to be in kernel modules, moved into kernel mainline to avoid the headaches of out of kernel driver maintenance. I'm not sure it is time well spent for developers, or end users, to develop yet another IR receive implementation in addition to the ones we suffer with now. I would also note that RC-6 Mode 6A, used by most MCE remotes, was developed by Philips, but Microsoft has some sort of licensing interest in it and it is almost surely encumbered somwhow: http://download.microsoft.com/download/9/8/f/98f3fe47-dfc3-4e74-92a3-088782200fe7/TWEN05007_WinHEC05.ppt "Microsoft recommends the Microsoft-Philips IR protocol (based on RC6) * You can become a licensee at no charge to you [...] * How to license RC6 * Contact RemoteMC @ microsoft.com for license agreement" I would much rather that RC-6 be handled as much as possible in user space than in the kernel. LIRC userspace components already handle it, IIRC.
