Phate,
I was hoping that you were the one how will answer me, according to your qustions on this forum it seems like i'm doing the same project as you were doing.
First i would like to ask if you finally make it work?
I configure the ADV via the I2C bus, i took the standard configuration file from the Altera DE2_TV demo:
https://www.alteraforum.com/forum/attachment.php?attachmentid=2666 As i understand this gives an auto fromat detection.
I realy could use any help, i really appreciate if you will send me your email on private.
Thanks again.

Well, I made it work, but only with NTSC. I didn't try again to detect PAL format because I lost lots of time and I was a little hurry.
Reading ADV datasheet, it seems that "altera audio and video config" configures ADV registers to autodetect both NTSC or PAL format.
BUT any of the registers the ip core writes on the ADV seems to be a little differents from the settings that are given in the data sheet.
I would try to config the ADV trough an I2C (taken form the an427, or from
opencores.org) and using the nios proc to write correct values to the ADV.
Well, I am not going to do it now, but maybe next week I'll try that.
I don't know if this is going to work or not, it seems strange to me that with NTSC the video ip works and with PAL not.
Because Altera tests wry well the ip cores is going to seel, i don't think is a matter of the video ips.
just my two cents.
Best Regards
