Cyclone III, Nios II evaluation KIt & analog video

--- Quote Start ---

I'm not sure about how interfacing with the analog front-end intalled in the multimedia Terasic board.

The multimedia-daughtercard has a RCA cinch input for composite video, that's all. Or did I misunderstand the question?

Hi FvM,

I know about the composite video input in the multimedia board of the cyclone III NiosII embedded evaluation kit. My request was for any reference design to capture analog video by using this input. I know about how to use deinterlacer, chroma resampler and color space converter from the video & image processing library, althought I don't know anything about the controller for the chip front end analog video.

thanks in advance

Hi FvM,

Thanks a lot for your information, I've downloaded the demos software called "IMAGEM_Technology_Demo" and I'll try to load in Cyclone III, Nios II evaluation KIt.

I feel that the luck is with me!!!

At leat the Terasic Multimedia Touch Panel Daughter Board (MTDB) has example files using analog video input. http://www.terasic.com.tw/attachment/archive/240/mtdb_vga_tv.rar

According to the MTDB documentation, it is configured as NTSC, but the decoder basically supports PAL or SECAM also.

I didn't check the project in detail.

hi fvm,

first all, thanks a lot!!! your feedback as always is very appreciated. I'll examine this information!!!.

I'm working in a project involving inspection by processing of thermal images using cameras based in infrared thermography .

I've developped the main algorithm using Matlab and after I've ported the code to Simulink-DSP Builder in order to simulate the behaviour of its hardware implementation.

I'm thinking of use Cyclone III embedded evaluation kit as main platform to work this algorithm, in order to doing that, I can connect an OEM camera using some of these interfaces,

*Analog video input. Video decoder in this board has only 8 bit, I think it's a little poor.

*video over LVDS. I can't see any conector for general purpose available in this board to be able to implement LVDS channels.

*video over Ethernet. NIOS+Niche_stack+Phy+Opencore. Fast enough to 320x240x12bit x 30fps real time video capture???

Any suggestion will be appreciated. Thanks in advance

As a preliminary remark, I'm not involved in digital video processing and have only some basic knowledge. Other forum members may give you more profound and detailed suggestions.

The ADV7180 used at multimedia daughtercard transports 10-bit digital video trough 8-bit interface, as far as I understand. It should be able to reproduce full quality with standard framed analog video. Alternatively, other daughthercards, e. g. Bitec digital video prodcts could be used at the HSMC expansion connector of cyclone III starter board or 3c120 dev kit.

I unfortunately can't report any experience regarding NIOS and IP stack performance.

I have to use the analog video input port on the Nios II Embedded Evaluation Kit, but I am having trouble knowing the IC ADV7180 (video decoder) which handles this port. Can someone experienced guide me about it?

Thanks in advance...:)

Hi prakhar,

I'm trying to do the same thing as you. I have checked a simple demonstration to see video either in LCD or in VGA using the analog composite video input. You can download it, and another advanced demonstration (all of them in VHDL code) from this link http://www.terasic.com/downloads/cd-rom/mtdb/

This demonstration is working well using NTSC video system, but I must use PAL system video input and by the moment I haven't been able to do.
