Ethernet to HDMI Gateway - A way to transfer video data over long distance

Abstract

Today the demands on electronic products are constantly increasing. This project deals with transmission of video data, especially over long distance. A device that could be able to increase the length from about 7 m to about 100 m when sending video was to be designed in this project. The task was to extend the length of a HDMI cable. The idea was to convert the signal from HDMI to Ethernet frames and sent it as Ethernet frames over a longer distance and then convert back to HDMI. In this project the Ethernet to HDMI conversion was designed. The device was based on a FPGA and should be able to receive Ethernet frames with video data and sends out the video data as a HDMI signal. The result is not so good, but it is easily seen from the results that the device receives Ethernet frames and then sends out the data to a screen.
