The Shenzhen 8K UHD Video Industry Cooperation Alliance has released its new General Purpose Media Interface (GPMI) promising more power and more data down the line
The General Purpose Media Interface (GPMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from a source device, such as a display controller, very much like your current HDMI cable, but then more from everything.
Specification of the new standard
GPMI supports data transmission rates up to 144 Gbps, accommodating ultra-high-definition video content such as 8K at 120 frames per second. It can power devices with up to 480 W of power. GPMI combines multiple signal types—including information flow, control signals, power supply, and audio/video—into a single cable, simplifying connectivity. It utilizes a sideband interaction channel to reduce device wake-up times to a quarter of those in comparable technologies. GPMI enables multi-channel bidirectional video transmission and mesh networking. GPMI operates in two modes: type B for 192 Gbps and 480 Watt with a proprietary connector and Type C for 96 Gbps and 240 W.
