Clear the Way for AV over IP!

While the term video over Internet Protocol (IP) has existed for quite some time, it essentially has been used to refer to any type of IP-based video transmission. However, regardless of the cabling medium, most of these systems to date have been supported by traditional audiovisual (AV) architectures where signals are sent and received via AV transmitters, receivers and video matrix switches rather than using true Ethernet LAN switches. This has prohibited AV transmission from truly converging onto existing network cabling infrastructures, and they have instead remained on their own standalone network. But all that is changing with AV over IP that uses standard network equipment to transmit and control AV signals.

A Step in the Right Direction

Over the past decade, balanced twisted-pair copper cabling (i.e., Category 6 and Category 6A) has become an AV-supporting medium using baluns that enable composite and analog video to operate over the twisted-pair cabling. The use of AV over twisted-pair cabling really came to fruition in 2010 with the introduction of the HDBaseT standard.

Since it was introduced by the HDBaseT Alliance, HDBaseT has evolved to support what has been dubbed “5Play”—the transmission of ultra-high definition 4K video and audio along with 100 Mb/s Ethernet (100Base-T), USB, bidirectional control signals and 100W of power (power over HDBaseT [POH]) over a single twisted-pair cable for distances up to 100 meters using standard 8P8C (RJ45) connectivity.
