A sore spot for Haiku (as the only successor to BeOS 'the multimedia OS'), is, well,... the lack of multimedia. Part of this, is TV and capture ability. Note, see the first video here ('About BeOS - Made by BeInc.' and scroll to 13:15/19:48 min - note the computer was a 233mhz with 64mb of RAM) for some of the video capturing and OS available effects one could apply within BeOS (not in Haiku).
The goal of this bounty would be to develop from scratch, or port existing TV drivers to Haiku and show the signal through BWindow. Further, integrate into the media server to allow applications such as TV+ or StampTV to make use of the signal. Optionally, and in addition, create an input server add-on to support remotes (with one supported hardware example - see BeRC, a LIRC port). Note, TV+ supports RC-5 remotes.
The goal would be to supply two out of three drivers for the following chipsets:
- bt848 & bt878
- saa1730/34
- contextant 2388x
and prove their function through the aforementioned TV programs. For more information, see Oscar Lesta's comments below (3rd comment).

Comments
(Maybe fellow-Aussie Sikosis can help with that)
I'm not going to apply, I believe others can do it better than I, so
take these comments as constructive, and disinterested ones.
1.- The scope of the bounty is to broad.
I believe, for my previous experience, that at least the BT8xx and
SA713x drivers could share a lot of code if the "analog tv stack" is
well designed. But it will be certainly difficult to manage to came up
with a working driver for such different beasts all at once.
2.- As far as I know... TV-O-Rama is tighly coupled to DVB-T/S, and
thus making it the "golden reference" is plain wrong. A far much
better target would be a TV app that only talks to the media_server
(StampTV, TV+, etc, etc.).

3.- Only mentioning chipsets and not specific cards as targets means
that unless "you" and the developer have the same hardware, you will
not be able to validate its work.
4.- I would remove the mail addresses of those Philips employees.
Maybe they still work there, but those address where old when I first
saw them (2004 at least). For the SAA713x I have, I believe, all the
Philips' official documentation there is for it. I could upload it
somewhere as to not have to email them repeatedly, or at least provide
a list of names/sizes/md5s of the files I have, maybe they are online
already.
So... I would be more specific on the bounty's target, and surely make
it a "multi-stage" one.
1st... Show the world that your driver for XXX is able to show the TV
signal in whatever type of BWindow you are able to for a particular
card(s) model(s).
2nd... Integrate that with the media_server, so one could use any
"video_in-aware" app to capture/show the signal (Stippi would agree
with this point).
3rd... Refine the work as to make it work for lots of more cards
(beware of vl4's list of tuners, there is a HUGE amount of overlap
there, ie: they have 50 different tuner types, with only 22 you could
cover ALL, really).
4th...Make input work for all the remotes, no matter of what chipsets
(ie: have a common api, and write an input_server addon).
5th... Create a Haiku clone of FlyTV2000 (the best TV app for Windows)
or of its evolution, BeholderTV.
Other:
http://www.ricin.com/freebsd/kbtv2/
A TV app for FreeBSD, with native drivers for SAA713x and others (cx25840, pwc). Also, FreeBSD has bt8xx drivers.
I would use that instead of v4l code as a guide (far smaller and maybe
less capable, but easier to follow). Use v4l drivers code only for
reference of certain hardware details, ie. documentation, unless you
plan to release your code under the GPL.
ahh I'll stick with donations to the printing bounty. thats a very useable functionality enhancmenet. If gnash worked better "or properly" you could use it on fancast etc. which gives you the same benefits of TV in.
or maybe get camcorder support going. I would love to be able to download my digital camcorder to haiku,but then we'd need a video editing utility.

Kind of makes you want to support this bounty too eh?
I have one rage 128 card all in wonder. I haven't seen a capture card like it in years. There are those new usb sttyle interfaces though for capturing old video tape and vcrs etc. IIRC though someone or several companies make firewire DVI generic capture devices for that purpose.
One bounty for DVI support could cover alot of ground.
