Do you need to support HDCP copy protection too?
If you need HDCP copy protection then the answer is no since this requires the video stream to be completely decoded and dual re-encoded. This is an extension of an application called a 'repeater'.
If you do not require HDCP then it is sufficient to simply buffer all the signals.
This question is probably better posted to the interface forums since this is not a video decoder/converter problem. I will try to transfer the question for you.
