FW: Digest Number 754 | FPGA-CPU | EmbeddedRelated.com

Digilent has a video decoder board. It uses ADV7183B which take video signal as input and generates YUV 4:2:2 format. But it does not have RGB linear output. I suggest them to use ADV7400 or ADV7402 but they didn't reply my e-mail. I could not find any cheap board uses SAA7111 series video decoder IC. If you know any please post a message, Thanks, Yusuf -----Original Message----- From: fpga-cpu@fpga... [mailto:fpga-cpu@fpga...] Sent: Thursday, June 23, 2005 10:23 PM To: fpga-cpu@fpga...

I was wondering what size the Altera FPGA is in comparison to the Xilinx devices. I have problems running the Altera Software as the license clashes with the Modelsim licence used for Xilinx Webpack - it uses the same environment variable. Has any one had any experience running the Xilinx software and Altera software together ? I'm still hanging out for a video and audio codec. I'd love to implement a graphics effects generator that allows warping and multiple video inputs in floating sprites :-) I've just been too lazy to sit down and design a video codec board. The FPGA board would also probably need a few more frame stores than you find on the average board. Even an audio codec would allow for some experimentation with speech filters companders and LPC synthesis / speech recognition John.. rtstofer wrote: >That's a very nice board! > >--- In fpga-cpu@fpga..., Alex Gibson <yahoo@a...> wrote: >>Came across this one >>http://www.terasic.com/english/fpga_01.htm >> >>Designed for multimedia.

I haven't got round to making a PCB and trying it, though.

Hi Yusuf, I did not think to check the Digilent web site. It looks like the Digilent Video decoder will only work with their high end Virtex II Pro board which is something I cannot afford. The FPGA board needs a Hirose FX2 100pin connector (probably for good reason). The ADV7400 looks pretty good. RGB output would probably be easier to manipulate and display. It would be easier to interpolate pixels with RGB I would imagine. John yiozturk@yioz... wrote: >Digilent has a video decoder board.
