Philips SAA7113A

[holistic]

Anyone familar with this chip : Philips SAA7113A

It is the capture chip for the ASUS6800 video card.

I read the spec sheet. I seems OK for full screen RGB/YUV with virtual dub.

Comments !

The Philips SAA7113 is a video decoder chip it simply converts an analog video signal into digital which in this case is passed to your CPU for processing into whatever you like. In is not a mpeg encoder. Many capture cards use this chip in the front end before the mpeg encoder chip.

Errr thanks norm , was aware it was not a mpeg encoder . Was intrested in how it faired against the others for quality of capture. ie. brooktree and zoran ! (is that the other?!)

[norm]

sorry about that misunderstanding. I'll have another go
It wouldn't matter whether the Video decoder was an SAA7111 - 7113 - 7114 or the brooktree series they all have CCIR601 - CCIR656 standard. In an imperfect situation like a computer it wouldn't matter if they were 8bit 9 bit or 10 bit or if they were sampled at 13.5 or 27Mhz. The front end is not the limiting factor as far as quality of capture is concerned,it is primarily up to whatever Asus is feeding the video decoder into before it reaches the PCI bus that will decide quality resolution etc. And of course what they have done with the drivers.
I'm not familiar with the ASUS6800 so I can't comment about its abilities.
It's not easy to compare any of the video decoders because there is alway something after that device which displays it on screen so if one card does a better job than another which part is responsible.
cheers...

My old Asus 6600 is the same as your 6800 except it was SDR instead of DDR. I can tell you that that card is the best capture card I've ever used. On my 1200MHz Athlon with Virtualdub I never dropped a frame, ever, at 29.97 FPS. Audio + Video was always in sync. Drivers were VFW so they actually worked unlike the WDM garbage.

Because my new GF3 has a Philips with worthless WDM drivers, I'm stuck with using my Asus in my secondary machine to capture. Its a great card and hard to beat. Quality is excellent, especially if you use the ASV2 compressor at setting 9.

THANKS for reply - norm , MHz

So norm, from what you say it seems the 'capture chip' (eg brooktree 878 ! ) has no impact on the quality of capture when it comes to ANALOG capture cards.
The problem lies in the "design" (for want of a better word) of the card chipset and associated drivers.

To extrapolate : a CHEAP well designed analog card
would work just as well as an expensive analog card (with same capture chip) so long as both cards adhear to the CCIR601 spec.

holistic - As all the video decoders ( SAA7113 ) have the same approximate specs it is up to the BT878 to provide the quality as long as the drivers are written correctly.
Conexant have done a good job with the BT878. As long as Asus havn't rewritten them. Which I don't think they have.
Go with what MHZ said.

Thank U good Sir

Any body know where to buy this decoder card that use saa7113 chip ???
I very2 need it to do my research...
I use interface from Nios Development Kit and connect to this decoder. My title is to detect vehicle traffic...PLzzzz

PLzz email me if want to mell anything about it...

I bought an Avermedia DVD Ezmaker PCI card in Nov. 2004 that uses the SAA7113 chip. It was purchased from www.tigerdirect.com

Older versions of the Avermedia card used the BT8x8 chips, which are not as good as the newer Philips chipsets.

The card fits into a PCI slot and has both S-VHS and composite video inputs. It uses WDM drivers and will not work with VFW type drivers. The WDM driver is on Avermedia's website.

The software that comes with the card (NeoDVD 4.5) is crap. I would NOT reccomend it. I use either iuVCR or Virtual VCR to record. This gives avi files which I then convert with Tmpgenc 3.0 express to mpeg-2 DVD spec files.

I have an asus 7700 deluxe. It uses the same chipset with 6800.

It's a great card with great picture quality. Use to have issues with drivers etc, but now all are solved.

In theory there are better cards. There are some with new 12bit conexant chips fir example.

In practice, if you are PAL you may consider switching to DV converters like Canopus 55 ADVC if you want something "more".

For NTSC users, I really don't know: I believe those early 00s cards are still top noch for analogue capturing

Erm thanx q 4ur answer. Buts anyone have any idea where to buy decoder that use philips SAA7113....
I really need it...because only video acquisition sub card with philips SAA7113 will work in my project....
ok thanx

MHZ,
I am very interested in how you got a VFW driver instead of the WDM garbage drivers..I have a FX5600 and it is useless with the WDM's..I even can't use the 1.08 version due to Hue shifting..
I am seriously thinking of trying it using Win98se(OK i realize thats a mistake but I am desperate)

Helo to all prends....
Everybody here can tell me how can i find decoder with SAA7113 chip ??
Is it any webpage that i can buy this decoder or any..
Pleasseeee
