This patent sounds very similar to HDBaseT, a cabling system proposed by Samsung Electronics, Sony Pictures Entertainment, LG Electronics and Valens Semiconductor. This technology uses an RJ-45 cable to transmit data via a 100BaseT connection, HD video, audio and power. The specification was finalized in June 2010, and products using this technology may debut in 2011.
Another similar competing technology, LightPeak, is being developed by Intel. The optical cable technology would be a single cable replacement for SCSI, SATA, USB, FireWire, PCI Express and possibly power and display connections as well. Apple is reportedly interested in this technology and was rumored, at one point, to be incorporating it into its MacBook Pro lineup.
