Hello all,

I am looking forward to display HDMI video on LCD. I believe I need a receiver IC which could be ADV7614.

please help me in choosing the FPGA, will spartan 6 work? what package should I use?

what are the other considerations which are imp in interfacing HDMI receiver with FPGA.

Thanks
 

Do you just want to display things on an LCD monitor? You can do this with just an FPGA, though you might want to use an HDMI buffer chip.

For a Spartan-6 solution, have a look at design.

If you want to receive video from some other HDMI source and then display it on a bare LCD screen (e.g. one with an LVDS interface) then this document may still help you, though the ADV7614 chip might do a lot of the work for you, especially if you want to support HDCP.
 

Dear Joelby,

Thanks,

Yes I just want to display the HDMI input from HDMI connector to LCD in RGB format.
I searched on net and found that ADV7611 can be very helpful and sufficient HDMI receiver.

You mentioned about HDMI buffer chip? Can you please explain what is that and where is it used?
And what else do I need to display HDMI input onto the LCD in RGB format.
Your help can save a lot of time so its very valuable..

Thanks in advance.
 

An HDMI receiver chip will probably make your life much easier if you need to support HDCP.

You will need to look at the data sheet for your LCD display to see what kind of input it accepts. If it's not directly compatible with one of the output formats of your ADV7611 (see page 12 of the ADV7611 data sheet), then you could consider using an FPGA to convert between the modes (other options: use a different LCD that *is* compatible, or use some off-the-shelf LCD driver chip that does the conversion for you).

You might only need an HDMI buffer chip if you're generating HDMI signals from an FPGA directly - it doesn't sound like you are planning to do this.

Hi;
To display HDMI video on LCD you will need a scaler design in your FPGA to fit incoming picture to LCD screen resolution. If you consider to display to interlaced pictures (such as 1080i@50Hz) then you also need a "deinterlacer" design. Since LCD driving method is progressive.
On the other hand as i know many LCD displays are LVDS inteface types (TTL interfaces are not so common any more, at lest high resolutions ie TV LCDs). This means you need a LVDS TX. This can be designed within FPGA or you can use some extarnal TTL to LVDS converter ICs.

Good luck.
