ABSTRACT:
A system is described for transmitting video signals over various communication media using digital signal processing techniques. An embodiment of the system uses an orthogonal frequency division multiplexing (OFDM) modulation process that enables high-speed data communications of Ethernet and/or MPEG or JPEG or H264 compressed or uncompressed digital video. A second embodiment frequency modulates the OFDM modulated signal (FM-OFDM). The first and second embodiments are implemented with a transmit Ethernet interface, an MPEG or JPEG or H264 compressed or uncompressed digital video capture device, and a modem including a modulator and demodulator that provides communication with several other modem devices along communication media such as power lines, wireless (air), cable, or twisted pairs.
