One nice day I had bought an ATI-TV tuner and found out
that bundled software is not quite perfect. Alas, the latest drivers ATI
offers at http://support.atitech.ca/
still contains some bugs and unpleasant features,
so I decided it will be faster if I change the software myself.
Most of this pages are in Czech language, because only some east-european users
are affected with a bugs contained in ATI Player. I will not update this english
page too often, so after releasing new version of my patch not all features
will be described here immediately.
If you are not interested in this page you can still look at
some pictures grabbed with ATI-TV :-)
Important: Don't wast your (any my ;-)) time asking me, whether
I know how to use ATI-TV or All-in-Wonder for decoding/descrambling of TV channels.
It is probably impossible.
New:
You can find technical information about AMC and I2C circuits
at http://www.atitech.com/resource_centre/dev_rel/tuneramc.html
Many thanks to Artem Krsheminsky who solved this problem and sent me the solution.
ATImisch allows you to redefine channels
as you need.
Tip for the curious ones:
Try to append "Debug=yes" into the "[I2CBusDriver]" section of ATIVIDEO.INI :-)
Attention: This patch may in some circumstancies render the
ATI player unusable. If this happens restart the computer and after reboot
choose "Undo" in ATImisch.
New: ATI Player 4.00 and higher don't need this patch.
"Connected to audio device only" message
If you have seen above message
("connected to an audio device only. no video capture will be possible")
when you tried to capture some videosequence, you
probably ask how to get rid of it. Well, it is quite easy when one knows the secret :-)
Non-tunable channels
ATI Player has a lot of predefined frequencies for different countries and TV
broadcasting systems. Alas it doesn't contain OIRT (CCIR-D) channel definitions.
I don't know if any TV station broadcasts at CCIR-D frequencies, but
common TV antenne (I don't know the exact term) converts high frequencies
(from 3rd TV band) to low ones (1st and 2nd TV band). Czech users cannot
receive this channels without changes in ATI Player. Exactly the same
situation happens with cable TV -- definitions of S01-S20 are different
for CCIR-B and CCIR-D.
Sound mixer TDA8425
As I've found out, ATI-TV uses TDA8425 circuit
for sound processing. This circuit has some nifty features, but you cannot
change them with ATI Player (treble/bass settings, independent left/right volume control,
stereo processing). If you want to play with this settings, you can download
ATImisch.
Teletext "noise"
You probably know teletext information is transmitted in invisible TV lines.
You usualy cannot see them on common TV receiver, but you can with ATI-TV :-(.
It is quite disturbing when you permanently see a few lines of random noise
at the top of a screen.
In ATImisch you can change the vertical position of
a TV image which will get you rid of this noise.
Czech teletext
I suppose this patch is of no use for users from any other country than Czech Republic.
TV-Online software bundled with ATI-TV card doesn't display czech characters with
accents
(e with caron, s with caron, u with ring above, o with acute, etc.)
correctly. I have added the definitions of czech character with accents into TV-Online.
