Sir:

I've been searching the web and the only HDTV video capture/TV card that
I found that is for sale in the US is ATI Wonder HDTV card model
100-714127 with remote control and other nice features, but only for
Windows ($139 and up, & SH). I've not found an OS/2 driver. I've
looked at Linux sites to see if there might be a Linux driver. There
is. but ATI wrote it and it is not open software. However, I saw that
there were other TV cards for Digital TV. Alas, as far as I been able
to track down, they were European Digital cards and not for sale in the
US. Any suggestion as to what I should do? I got a few years before
Digital TV become mandatory.

I can't find any detailed specs (i.e. chipset) for that ATI model
number, but a sales-type description I found suggests that it uses one
of the Radeon chipsets.

If so, SciTech may have an answer for you.

i own a JVC GY-HD100E ProHD camcorder and eCS firewire drivers
do not recognize it :-(
so i can't even acquire m2t (movie) files from the HDTV camcorder...
i'd really like to watch HDTV with the PC (under eCS)
bye

Sir:



The Firewire drivers that are available are like the corresponding USB
drivers. These only provide the base drivers. Someone needs to write
the device driver that would handle the analog video from that
camcorder, just like someone wrote the mass storage driver for USB.
That camcorder is not cheap. To use it now, I'd suggest using the
existing drivers that came with the device on that other Operating System.

In order to try HDTV at minimal cost I bought a set top box with VGA connector
and plugged in a computer monitor.

I prefer analog TV because it rides through signal brown outs where digital TV
freezes when the signal fades.

The authorities here have conceded they will have to delay the analog shutdown
because the digital take up is less than anticipated. You might have more time
than you have been told.

Sir:


The US authorities are very pissed at the foot dragging that has
occured. That is why the purchase of analog recievers will be stopped
soon. Although the original law allowed delays, Congress is impatient
at wishing to assign the analog bandwidth to other uses. Do not be
surprised that the US Congress passes a law this fall pulling the plug
all analog broadcasts by 2009.

Be sure to have really powerful hardware. Software decoding
of an 1920x1080 HDTV stream will bring an Athlon XP 2100+
system to it's limits. Depending on the graphics card, we
are getting about 90..100% CPU load. Not to mention, that
some graphics cards cannot handle overlays of that size...
But the picture quality is *AWESOME*.

And no, I don't have a driver for a digital TV card under
OS/2. I was just testing if those files would be playable.

Sir:



Are not HDTV streams encoded as MPEG4? That would demand hardware
driver for video card chip that can do this decompression, no? This
limits the number of cards available that have such a chip. That in
turn infers that there are very few production chips that do MPEG4
decode? The ATI All-in-Wonder card I mentioned has MPEG4 capture and
playback. Plus these two ATI cards have MPEG4 playback: Radeon 9550
model 100-437105, & x800 XT model 100-435210. (I limited my search to
ATI.) You would have to write a driver to use these MPEG4 playback.
Scitechsoft does not generally support advance features like this. I
know that they never supported the MPEG2 playback features of the S3
video cards that I have. I also found some products using a Phillips
7134 chip for MPEG4 playback.

There streams that were give to me were MPEG2 at 16Mbps. I heard
that some discussion is going on about MPEG4, but at least here
in Germany that seems to be experimental only. The transition to
digital TV is fully in progress but the base technology is MPEG2.



I cannot comment on these.



Latest SNAP versions do have some MPEG decoding support for ATI cards,
but I'm not aware of any software taking advantage of it. AFAIK, some
SciTech customers for embedded solutions do, but they are not running
OS/2.



The advertising for this chip is somewhat misleading. The SAA7134 has
absolutely zero MPEG decoding capablity. It is used on some digital or
hybride TV cards, however in digital mode it only works as PCI bridge.
All cards using this chip are doing software decoding and if they are
sold as "PVRs" then the MPEG encoding is done by the host PC in software
as well.

you can play this with the latest version of WVGUI on Netlabs'ftp...
it play very well with "only" 72% cpu load on my system
Athlon XP 2600+ with 1GBRam/PC3200 and Matrox G550 under eCS, of course

I have downloaded the file and the CPU load is about the same. The
latest
version of WarpVision seems to have gained some speed... Currently I
cannot
test it with EmperoarTV's MPEG decoder (which I used run the other test
on),
since I need to add support for transport streams first ;-).

The files I already got are program streams and tend to consume a bit
more
CPU load than the one you mentioned. Unfortunately, WarpVision stops
after
a few seconds, but it looks it will end up with about 80%.

BTW, my system is an Athlon XP 2100+ with 256MBRam/PC2100, nForce1
integrated graphics (GeForce2, shared memeory architecture)

(OT) the JVC GY-HD100E is really an impressive camcorder!!! ;-)


when it will support mpeg2-ts and Hauppauge Win-TV PCI consider me as a
buyer :-)

Did you create the file with that camera ? Is this professional
equipment ?



Well, as I said before: it's very unlikely that I will ever support
"traditional" TV cards. Transport stream handling is required for
DVB, which is more likely to come in the future...

Is there sound on this clip? I don't hear anything.

[Am using a slower CPU; latest WVGUI & WarpOverlay.]
[With my setup, .avi files play well (video+sound).]
