After speaking with Scott on Friday, we learned that it would be extremely difficult and impractical to try to connect an Arduino as a substitute for a P.B.C. board to the transmitter and receiver we have, and so yet again we are unsure what our final deliverable should be.  However, Scott suggested we make a poster,  much like what Professor Taskin suggested a few weeks ago, of what elements we would put together to make the HDMI transceiver based off of the A/V transmitter and receiver pair we have, as well as block out how the actual function of the transmitter and receiver we have already work.

An example of a similar block diagram was shown to us by Scott, and is displayed below as well.

Above is a block diagram of a AM transmitter.  The microphone converts the audio input (AF) into electrical energy. The driver then amplifies the audio, and the modulator further amplifies the audio signal to the amplitude necessary to fully modulate the carrier.  Adjacent to the AF line, the RF line has a different role before the two lines meet at the power amplifier.  The oscillator creates a wave with a high frequency and sends that wave to the buffer amplifier, which, as presumed, increased the amplitude of the wave, or signal.  Then, when the two waves conjoin, the wave from the AF line and the wave from the RF line, and amplitude modulated signal is created and then sent through the air to presumably the receiver.

For an A/V transmitter and receiver pair, as well as an HDMI transmitter and receiver pair, the format would be a little different, for example the transmitter would probably not be AM, and the video signal would also have to be converted using a video amplifier, driver, and modulator.  For our purposes, the above diagram can be very useful for creating our own template of how we would make out HDMI wireless device, and so we will reference it while creating our final deliverable.
