HDBaseT Alliance White Papers
There is a clear trend and market need for high-power transmission over cable. Power over HDBaseT (POH) enables the transfer of DC power in conjunction with data signals over a single Ethernet cable to a distance of up to 100 meters (m). The POH standard includes definitions of the power source equipment (PSE) and the powered device (PD), and this paper will describe the detection and protection mechanisms that were set in the POH standard to ensure safe and reliable power is delivered to the HDBaseT network. We will also review the benefits of using POH for the HDBaseT top target applications.
The criteria for connectivity in the commercial market varies from that of the consumer home installation market. Until now, commercial installations have made due with more home‐centric technologies and cables, as only a few cable standards can accommodate the feature set required for audio/video (A/V) connectivity. However, these standards−designed specifically for the consumer electronics (CE) market− place limitatons on commercial integrators in terms of cable reach, feature capabilities, ease of installation and overall flexibility.
Clearly, wired home networking technologies are everywhere. MoCA is using coax, HomePlug rides over power lines, HomePNA is using telephone lines and G.hn claims to be able to work with all infrastructures. Some are more popular in North America and some in Europe, some provide more bandwidth and some offer more reliability, but all of them can fall into the category of compressed networking technologies.
