DS90C387: Play mp4 files from USB. Any recommended diagram?

Part Number: DS90C387

Hi all,

I want to design a circuit that reads mp4 files from a USB flash memory and plays them on a 40 inch LCD panel.

Inputs:

  • USB
  • HDMI IN (optional)

Output:

  • 51 pin LVDS
  • HDMI OUT (optional)

So far I've discovered DS90C387 IC which serializes the 24-bit RGB signals into LVDS format, so that I connect them via an LVDS cable to the LCD panel.

But the question is how can I convert mp4 files into 24-bit RGB signals?

Thanks for your time and help.

    Hi Omid,

    The DS90C387 is designed for use with RGB data, so the DS90C387 can certainly be used to convert from RGB to LVDS. However, you will need a processor before the DS90C387 to complete the conversion from mp4 to RGB. It may be possible that a Sitara device like an AM57xx may be able to do this. I recommend requesting advice in the Sitara forum to see if they have a solution for this.
