FPGA's & HDMI/HD-SDI

Postby tbrocato » Sun Aug 03, 2014 3:35 pm

I have been following this class from day1 and love it... Learning alot, bought the kit, and love seeing how easy it is (or how easy it looks)...

I work in broadcast television and am trying to learn and see if it could eventually be possible with the FPGA i currently have to do either of the following.

HDMI, HD-SDI (encoded component video), and of course cool audio DSP stuff, equalizers, multiplexing/mixing, effects, etc.
I'd love to create a little project where it would pull video from memory of some sort and output an image. or even learn how to do conversion from hdmi to sdi and vice versa.

I found this website but it looks like it isn't using VHDL ... http://www.fpga4fun.com/JTAG2.html

It explains how to do some of these projects, is that going to be a good resource after this tutorial is completed?

Resources for SDI:
http://en.wikipedia.org/wiki/Serial_digital_interface
http://www.silabs.com/Support%20Documen ... /AN377.pdf

Is this something that can be done with VHDL, is the test chip fast/big enough. Any help or guidance would be greatly appreciated.

You'd prob drool wildly when seeing the milkymist project (opensource) , but might be a "tad" advamced for us beginners :wink:
But lot's of "inspiration"

Hello,

HDMI can definitely be done on FPGA.

As an example, most Xilinx development boards (e.g. http://www.xilinx.com/products/boards-and-kits/EK-A7-AC701-G.htm ) come with either a DVI or HDMI video port, sometimes even both. And they have example code for the board to show how to output video using those video ports.

Is a good resource for FPGA modules. You will find modules written in both Verilog and VHDL languages. In the Lesson 10 of this course, we will briefly use verilog to build an example module, so you will get a taste of it before the course is over.

As for doing video output. FPGAs are uniquely very qualified for outputting digital video signals because they are great at sending out digital bits at high data-rates and with exact timing. You will likely need an external RAM to work with if you want to do dynamic screen refreshes.

Some examples of simple VGA:
