Another method used to help discover the hardware settings required for a bttv device is running the device under a Windows OS with video software and the BtSpy [1] [2] monitoring. This is what I’ve done Debian Sarge testing, kernel version 2. It might work, but if there’s a more specific one for your specific card in this wiki, you should use that one. The Kodicom R and Kodicom R cards and their many clones are supported by the bttv driver from kernel version 2. If anyone sends me information about this point, it will be very appreciated.

In my board the 94 is not used, the and 98 are connected to the same copper trace and from there to the tuner sound output. Fusin are doing it with our Bt! We should ear again a noise signal or a sound if we have a TV channel tuned what comes from the tuner, but now it’s going out from and into our PC.

About this document, we conclude what: Yes, the number of digits is correct. Anyone can guess from which kind of signal this spectrum comes? In my system I got this message after depmod command “depmod: The inner computer interferences. But don’t worry, if you have some load plugged and the incoming signal is strong enough these interferences almost disappear. Views Read View source View history.


If anyone sends me information about this point, it will be very appreciated. You fuxion get the source from here btaudio We will wire outside also the tuner audio output to be able to use this resource in the future. I’m not sure they all use BT8xx chips. If your board does not use the ADC inputs they are not connected to any copper track I suggest not to use it, because it’s very difficult to solder tb878a a SMD chip and you will need tools that are hard to find.

If not, vt878a should try this howto here, and if it works, add this section to your card’s article in this wiki. You have one device the A with multiple inputs, of which only one at a time can be active.

Audio input circuitry reference voltage. Learning what these parameters need to be for your specific device may not be a trivial task.

Bttv devices are collectively those PCI cards that are based upon either a BtBt or Fusion A chip, and which are supported under Linux by the bttv and associated kernel driver modules. It’s not necessary to see perfectly the television image. Some bt capture cards have a single chip on board and four inputs on the card’s PCI riser. But there are also signals at higher frequencies noise which are the best proof that we are digitalizing much higher, up to Khz approximately.

Doesn’t matter how good soldering we are or how short the unshielded copper we leave, we will suffer some interferences due to the amount of electronics around the BtA. EasyTV build by Prolinkmodel: The b878a supports downsampling by powers of two, so you can ask for more usual sample rates like 44 kHz too.


The mod concept is: I may have missed a couple of options.

In theory, different PC models create different interferences and is important to know them to avoid getting wrong results in our experiments.

We can call this input: Retrieved from fision https: It might work, but if there’s a more specific one for your specific card in this wiki, you should use that one.

Our pins are the98 and the 94, which are the ADC signal inputs. This page has been accessedtimes.

The power of the actual Personal Computers PCgive us the possibility to analyze and manipulate complex analog signals, but first we need to digitalize them using an Analog to Digital Converter ADC. To bt887a an ADC what permits us digitize at the higher frequency as possible, using “off-the-shelf” hardware.

Once the card is installed and the system is running we will do a test to find out if the soldering is right.
