RE: [beagleboard] OMAP35x HDMI (Video + Audio)

Can you get HDMI chips without the crypto/DRM protection? Thats the main reason the chip maker is protective of the HDMI design.

Not that I am aware of. There aren’t that many people making those devices that will even deal with someone unless you want to talk 5 figure quantities. Plus, there is the whole NDA thing. I don’t know if there is anything out there that does not have the encryption.

Zoom OMAP34x-II Mobile Development Platform includes SiI9022 HDMI
encoder (TFBGA84 package) on baseboard schematics.

Please have a look at http://omapworld.com/zoom.html (registration
required for schematics and layout) and http://www.siliconimage.com/products/product.aspx?pid=118

No HDCP is enabled in Sil9022, but NDA will for sure still be required
to get datasheet. However, it should be possible to implement the IC

I totally agree, but sourcing the chip in like 100+ chips volume is
unfortunately nearly impossible (at least when I tried some time back :slight_smile:
In case somebody have a better connection to Silicon Image than I have it
might however definitely be an easy HW/SW-way forward...

I totally agree that having a full HDMI add-on card for Beagle would be
great... :slight_smile:

  You can buy trays from distributors - <http://www.sequoia.co.uk/> and
others will sell them. However,

  * For HDMI, you need to have signed the HDMI adopters agreement
   ($5k - $10k/ year + $1/10c per unit royalty) and have the first
    device of each type externally certified.

  * For HDCP you need in addition to agree to the HDCP consortium's
    rules and pay another yearly fee. I'm not sure what the certification
    is for that.

  You can buy HDMI encoders without HDCP (in fact, I think 9022A does
this), but not, frustratingly, HDMI decoders. The HDCP agreement
obviously prohibits you from taking HDCP content and emitting it
as pure HDMI.

  You need NDAs for the chip data, but this isn't usually too much
of a problem since (a) the Linux kernel contains drivers for quite
a few of these HDMI driver chips, and (b) you're signing all sorts
of horrible agreements with the HDMI/HDCP people anyway.

  9022A works nicely with a beagle's LCD output and seems (shockingly
for I2C) to obey commands sent to it without complaint. Get the
TQFP version though; you don't want to tangle with 0.5 pitch
BGA unless you have an appetite for very expensive boards.

  FWIW, we looked into this a while back; it's perfectly practical if
you're prepared to stomach the $15-$17k certification startup
costs and subsequent $5k/yr + $1/unit licencing. We weren't :slight_smile:

  (though we do have some prototypes lying about if anyone is close
to us and wants to experiment)
