[9fans] TV/FM tuner

[Kenji Okamoto]

Ok, I got a TV/FM tuner card, KW-TV878F, which is now recognized as
#V0: Brooktree 878 TV tuner (rev 17) (MIRO/TEMIC PAL_I) intl 11

and bind -a '#'V /dev shows me a directory structure like:
/dev/tv0/audio, ctl, regs, and video.

cat /dev/tv0/ctl shows:
640x480x16 RGB16 channel 0.

This card also has FM tuner, and I connected the audio connector to
powered speaker, yes, I'm now hearing FM noise from it.

Now, what I can do to watch TV?

It seems to me there is no client program for this.  Am I searching wrong?

I forgot to describe the hardware I' using.

Celereol 466MHz, and on board Savage4.
TV tuner: AOpen VA1000Plus  (Fusion 878A, and low profile)
Memory: 384MB
Antena:  in door Antena with booster

  What exactly did you do to get a picture and sound ? An exact sequence 
  of commands/steps will be appreciated.

Thanks,
Roman.

1) make change to /sys/src/9/pc/devtv.c for Fusion 878A.
2) make small change to /sys/src/cmd/tv/tv.c for Fusion 878A.
3) if you are living outside US, check your frequency range, and add them
to /sys/src/9/pc/devtc.c.
	The second source is not open so far.
3) cannot use overlay mode for Savage4, then make a command like:
term% tv -C10 -l

where C10 stands for 10 channel in japan, and l means use local device.

Oops!
devtc.c -> devtv.c.

Now, I put the Fusion_878A chip to a cpu server, and import to every terminal
the device.   Now, we can watch TV from anyterminal with a 878A device.
However, the Fusion 878A chip has no independent audio processor, and just
has it locally, you cannot import TV audio device.

checked hardware:

KWorld: KW-878F
AOpen: VA1000Plus

Then, I checked drawterm with TV.

I logged into the cpu server, which has Fusion 878A device in the kernel, through
the wireless (56MB) network using WinXP, and binded '#'V to /dev, then, tv -n1 -l!
Wow, I can see the TV on the drawterm window, which is slow though.

Hmm, interesting!

Slow for 640x480x16 window, of course.

>the wireless (56MB) network 

Sorry, 54MBps (802.11g).

Then, I changed the channel from 4 to 6 (Japanese local sorry), the
TV program on the drawterm changed of course, and another 9 terminal's
TV channel did same.☺   Well, of course, it should be so, because I'm sharing
the same TV device hunging on a CPU server...   Silly, but felt interesting.

  I don't see this program in the latest bits from
  http://www.cs.bell-labs.com/plan9dist/

  Where did you get it from ?

Thanks,
Roman.

Go personal to Peter Bosch at Lucent.
You can find his mail address from the archives of this list.

Could you let me import your device over the internet? :)
