The traditional way to watch TV on your PC is using a PCI add-on card, like Hauppauge's. But using a VCR and your video-in featured nVidia board, you are also able to watch TV. But it is rather expensive to go out and buy a VCR just to be able to watch TV on your box.
Asus realized this, and introduced the first generation of all-in-one cards. They offer two cost effective ways to watch TV on your PC called Asus V7100 Combo Deluxe and Asus TV-Box. Also VisionTek and Creative sell such a box that we call 'BreakOut-Box', and the AOpen MX400-A32 card has a on-board tuner, like the V7100 Combo Deluxe does. The LeadTek company sells a tuner box called WinFast Cinema. This box is also supported by the driver set.
More recently nVidia themselves developed the "personal cinema" chipset that is now used as the basis for most nVidia-based all-in-one cards.
/usr/src$ tar xvzf bttv-0.7.101.tar.gzAfter this, build and install the bttv package:
/usr/src/bttv-0.7.101$ make /usr/src/bttv-0.7.101# make installRivaTV releases contain a subset of the necessary bttv drivers. They get compiled and installed during the build process. Efforts have been made to get the bttv-0.9.x drivers working with rivatv as well. Thus it is possible to use rivatv on 2.6.x kernels with the 0.9.x bttv drivers.
nVidia Chip: GeForce2 MX Model: Asus V7100 Combo Deluxe Architecture: NV10 (NV11) Access: Control [0xde000000-0xdeffffff] FB [0xd0000000-0xd7ffffff] Interrupts: 0 out of 976 (DMA: 0, Overlay: 0, Missing: 976) Device: available VideoDecoder: SAA7113H Tuner: (unset) AudioDecoder: tda9850 AudioProcessor: tda8425 IR chip: unavailableNow, you should be able to use your tuner by selecting the "Television" channel in xawtv. If the modules did not load automatically, just try loading them by hand:
$ insmod tuner.o $ insmod tvaudio.o $ insmod tvmixer.o
We know of two types of TV-Boxes: They have a TDA8425 or TDA9873 audio
chip, and an FI1216 tuner for PAL or an FI1236 for NTSC. There may be
other models. If you have one, please let us
The TV-Boxes are enabled the same way as the V7100 Combo Deluxe, with one difference: When you load the rivatv module, set the tvbox parameter according to what tuner you have: Use 1 for a PAL tuner, and 2 for an NTSC-M tuner. Example for PAL:
# insmod rivatv.o tvbox=1This way, an additional channel "TV-Box" should be selectable in xawtv. You can switch tv channels with appropriate channel tables which are built in xawtv. With audio enabled you are also able to control volume, balance, etc. With the tvmixer module (an OSS interface to the audio mixers) loaded the audio channel can also be controlled by a mixer program, like xmix, kmix or alsamixer.
Some graphics cards which come with a TV-Box cannot be identified by RivaTV (e.g. the VisionTek Xtasy Everything Personal Cinema), and RivaTV is therefore unable to determine the correct input modes of the video decoder chip. That is why it is necessary to tell rivatv the correct board by passing the card parameter. The list of card numbers can be found in the CARDLIST file.
# insmod rivatv.o card=55 tvbox=1The "Personal Cinema" variants by Creative and VisionTek do have a input/output multiplexer chip (the PCF8574) built in their BreakOut-Box. On the one hand this chip is responsible for providing the IR information on the I2C bus and on the other hand it also controls the PowerIn line of the tuner chip. That is why you need to apply the LIRC patch as described here until the output of /proc/driver/rivatv reads
... IR chip: presentWhen you still have problems getting a video picture from the "TV-Box" channel you can try to issue the following command which sets the input channel explicitly (works for the SAA7xxx video decoders).
# echo "VideoDecoder: 2 = xx" > /proc/driver/rivatvThe "xx" represents a hex number in the range c0 .. c7, d0 .. d7 or e0 .. e7. When you get it working with one or more of these numbers please tell us!
