On my blog you can read what happened to this project in the last months.
Here some Details... I have reduced the size of the PCB and also removed bluetooth and the HDMI processor. I have removed those parts because I haven't used the bluetooth connection so that it pays for itself.
The HDMI processor is removed because I haven't the time to processor further development. And there are several HDMI2CVBS devices for less than 20€ available.
Those converter are able to handle up to 1080p Video with HDCP support.
