New Video IP example design for 3C120 board is available

I have extended the current Cyclone III example design by introducing some of the new IP features added in Quartus 9.1. Specifically I have added two frame readers and two control synchronisers to provide an on-screen logo image from a ROM, and a graphics screen from DDR memory. The control synchronizers are used to perform smooth centered-zoom and layer switching functions. The .zip file includes an "Extended example design.ppt" presentation which also explains the changes.

I recommend that anyone wanting to try this out should get the standard example design working first. Then, the only "gotcha" is to do the linker edits so that the NIOS uses the on-chip RAM instead of the frame reader's DDR - be sure to follow the instructions in the README.txt.

Jon.

    Thanks for posting this. Seems like you got a bunch of different things working all in one design.

    What else do you need with the Cyclone 3c120 Dev board to get this to work?

    Hi Vipjon!

    Thanks for sharing your effort. I appreciate this as i tried to implement OSD using Video Example design of Altera for EP3C120 as reference but failed in my attempt. just started downloading your zip file.

    I haven't changed the setup of the development board at all, it's the same as for the documented example design. I've just enhanced the on-FPGA VIP to introduce the extra features.

    There is no H264 encoding in my design - this is purely manipulation of raw video streams.

    In understanding what to do, you need to make a call regarding the format in which your video needs to be streamed back to your web browser (client). Once you know your options, in this respect, then you can start figuring out what to do on the server side of things.

    Wikipedia has some decent information: http://en.wikipedia.org/wiki/streaming_media

    Best of luck!
