Ethernet Power Harvesting Spectra7 provides for Power over HDMI. The Ethernet Alliance has a Power over Ethernet (PoE) programs "With total PoE-enabled port and device shipments projected to reach nearly 1 billion by 2021,"
Looks like Spectra7 is scheduled to help with this in February:
"Providing an easy means for identifying interoperable PoE products, the Ethernet Alliance PoE Certification Program includes a public registry of products certified to the organization’s requirements. Building upon the success of the first generation of the Ethernet Alliance PoE Certification Program, Gen2 addresses the IEEE 802.3bt standard, which supports sourcing up to a maximum of 90 watts for higher-powered devices and equipment. It also incorporates an updated test plan, based on the IEEE 802.3bt standard,
developed by members of the Gen2 Contributors Group of the Ethernet Alliance. The test plan is scheduled for validation during a University of New Hampshire InterOperability Laboratory (UNH-IOL) pilot test event in February 2019, at UNH-IOL’s lab in Durham, N.H." Participating Members
