Background Information

Our motivations for creating a wireless HDMI device was to have something that didn't require long cables to transmit a video signal, as well as to expand our knowledge in wireless telecommunications. For this project, our ultimate goal is to create a prototype of a transmitter and a receiver that can wirelessly send an HDMI video signal across a room.  However, with the extreme likelihood that we are unable to do that due to the previously unforeseen obstacles in finding a strong enough transmitter for the huge bandwidth HDMI uses, we will go about finding other alternatives to HDMI video, such as standard definition, to reference and use as a base for if we wanted to expand upon the project at a later time with more knowledge of wireless and circuitry.

Testing

The A/V transmitter/receiver pair was tested using a PS3 in combination with a spare television monitor. First the PS3 was tested with the A/V cable plugged directly into the television. While attached to the television directly, the video quality was fuzzy but functional and the feed was stable; the audio quality was fine. In order to test the A/V transmitter/receiver pair the PS3 was moved across the room from the television. The transmitter sat underneath a desk at sixteen feet from the receiver, which was behind the television. The pair was tested along channels one through four. While ascending between channels, each consecutive channel had a less intermittent signal. While using the transmitter/receiver pair the video quality was about equal to that of the wired connection while transmitting along channel four. Even on channel four the feed still occasionally had the white glitches similar to the type that would come through on an old VCR. The wireless sound had an added buzz to it that was similar to the buzz that comes through while listening to the radio.
