Hi,all:
I need a simplest PAL/NTSC decoder, just one composite-video(or CVBS) input and a group of analog R/G/B/Comosite Sync output . Could you give me some help ? Thank you anyway!

Best regards!

U can use SAA7111 or SAA7113 as decoder.

Thank you all! I think what I need is a RGB decoder. Yesterday I read some SPECs such as sony cxa1585q, maybe ICs like this will fit my application. Because cxa1585q only support Y/C input, so I must add a Y/C seperator, Could you give some good choices? Thank you.
P.S. I've heared that SHARP's IR3Y31M/3Y29M is also ok, but I can't find their SPECs, Could you help me ?

If you do as kivi says and use SAA7113 to convert to ITU656 video you could use and DV Encoder to convert back to NTSC such as Philips SAA7121, SAA7129,AD7171KSU,STV0018,BT864........

ASIC

around $5 in volume (possibly 500k) for Philips 7113 more expensive in Japan ($6~7)

as far as I know, most vendors support at least 4 CVBS inputs (therefore 2 CVBS + 1 Y/C). vendor list:

Philips
Micronas (formerly Infenion)
STM
TI
Conexant (formerly Brooktree)

Does anyone know where I can find the source code of such a decoder?
Also where can I find some raw video data sampled at 27MHz?
Thanks!
