Video Input to AM3894

Yes, but you will need to add an external HDMI reciever.

The processor has a generic video input which can accept inputs from various externally connected devices such as video decoders, HDMI/DVI recievers etc...

For HDMI/DVI you will need to sign up as a HDCP licensee in order to be able to purchase HDMI/DVI receivers which are able to accept copy protected video streams though. If your source does not generate copy protected video then you can obtain HDMI/DVI receivers from a few places such as Digikey etc...

Steve,

Thanks for the reply, you lost me at the end though........If customer is not generating copy protected video then he can use HDMI/.DVI receivers fromDIGIKEY??? DIGIKEY doesn't make HDMI Receivers, are you saying TI has no "NON-Copy protected HDMI/DVI Receivers"?? So I would need to go to another supplier(I.e. ADI or someone else) for that?

What is the interface to the AM3894 that these receivers would connect to?  The customer would still need the HDMI output for sending to a display..So hopefully the Video input you are mentioning is not that port.

Let me know

Thanks

Charles

Charles,

Digikey is a supplier not a manufacturer. The point I was really trying to make is that you can buy HDMI/DVI recievers from many manufacturers on the the open market from suppliers and distributors without any issues as long as you don't want copy protection enabled receivers.

The issue is not in the generation of copy protected video, but the receiving of copy protected video. The movie industry does not want you making a device that can strip off the copy protection.

If you want to be able to receive copy protected video then you need to work with the HDCP licensing group and your distributor since there is a $5M+ indemnity requirement and a whole slew of other legal requirements/NDAs etc...

TI does have a DVI receiver. Look at the TFP401 and the HDCP enabled TFP501 (the TFP501 requires that you purchase HDCP encryption keys directly from the HDCP licensing group and program them into an external EEPROM)

The interface to the DSP is through a 24 bit parallel interface. There is an integrated HDMI transmitter and the output is always available and not shared with any other signals.

Steve,

Thanks for the reply, I probably mis-stated the orginal question. The customer has a processor which is outputing Display Port, that output needs to be sent to the AM3894 processor, so since the AM3894 doesn't appear to have Display Port input...There must be a DP receiver placed in between the processors.. Does TI have a DP receiver that could be connected to the AM3894?

Charles

Charles,

The issue is still basically the same though, although possibly more complex for DP since I am not aware of any DP receivers without HDCP.

TI does not have a DP receiver, no, sorry.

Finding a DP receiver that does not require the same HDCP licensing agreement will possibly be difficult too.

Can the source processor output in any other formats, i.e. digital parallel or, as you initially mentioned, HDMI/DVI? TI does have a DVI receiver without HDCP.
