Description

This project is an MPEG2 video decoder. The decoder converts an MPEG2 stream into a RGB video output. To get a functioning decoder, you will need to add at least the following additional components:

  • MPEG2 video source
  • RGB video output
  • memory controller

The input of the decoder is a MPEG2 stream. This could be streaming video over ethernet, a tv or satellite tv tuner, or a file on flash memory.

The output of the decoder is a Red/Green/Blue (RGB) video signal. This can be connected to a VGA, DVI or HDMI video output.

The decoder also needs a memory controller and RAM as a scratchpad memory, to store decoded video images.

Lastly, if your project includes a small micro controller, you can use the On Screen Display (OSD).

What this decoder does not do:

  • The decoder does not decode audio. To decode audio you need to add an MP3 audio decoder core, and you need to synchronize video and audio.

Tested & Verified on Xilinx ML505 board.

 

Contains testbenches based on iVerilog and GTKWave.
