Hardware encoder chip for DVI

[Semilue]

Hello posters,

i am a student of electrical engineering. For a project i am looking for a hardware solution. We want to get video data from the digital video interface and transmit it via WLAN.

That are the conditions made by the professor.

So could anyone tell me about a encoder chip which accept inputs via DVI. Behind the encoder chip we want to place an ethernet controler to send the video stream via WLAN.

Thanks everyone for helping commentaries.

When you say encoder, what do you mean? Encoding to what? Also, is this SD or HD video?

[Semilue]

I want to encode it to compression standard, e.g. MPEG or h.264. It is HD. Up to 1280 * 1024 resolution.

check the Analog Devices wavelet encoder/decoder ic's eg ADV212 (they also produce HDMI/DVI receivers)

That seems not to be the solution. This chip only accepts interlaced pixel data.

Other comments on my problem?

I think that You missunderstood datasheet for ADV212

AD says:

"The dedicated video port of the ADV212 provides glueless connection
to common digital video standards such as ITU-R BT.656,
SMPTE 125M, SMPTE 293M (525p), ITU-R BT.1358 (625p),
SMPTE 274M (1080i), or SMPTE 296M (720p). A variety of
other high speed, synchronous pixel and video formats can also
be supported by using the programmable framing and
validation signals."

So You can put both kind of video (interlace or progressive) up to the 65MSPS (any kind of video up to 4096x4096) and this can be compressed. For fastest encoding more ADV212 can be joined together (parallel processing).
So if You dont need a standarised codec (h.262, h.264 etc) then one or more ADV212 should be fine for You.

I think that HDMI/DVI receiver + one (or more) ADV212 (number of ADV212 depend from pixel rate of Your capture which is for one ADV212 is limited to the 65 milions pixel per second), some uC with ethernet interface IMO ARM like STR912 familly or maybe better different ARM with MMU should be ok (with MMU You may use normal Linux as a embeded OS), some glue logic, maybe additional RAM/ROM and this all should be solution for Your problem.

you can go between DVI and HDMI, so I think this is what you need

The drawback is you have to compress using software and only standard HD resolutions are supported (1280x720 or 1920x1080).

Thanks everyone,

but i agree with pandy. I got in contact with analog devices and described them my application. They offered me the same chips as pandy and guaranteed me that it will work with that.
