ETSI has published a technical report (http://tinyurl.com/po7yj4l) that analyses the benefits of powerline HDMI (PHDMI) technology for HD/UltraHD video transmission. The report aims to define the technical elements required to establish a PHDMI specification.
Powerline technology involves sending signals, most commonly internet, over power cables. ETSI’s Powerline Telecommunications Technical Committee’s report investigates the transportation of uncompressed HDMI video over short-range links. Both single input single output and multiple input multiple output capabilities were examined, along with specific compression schemes.
Target applications include multimedia wired high speed links in home video networks, or video surveillance systems operating from multiple HD and UltraHD cameras.
