At CES 2019, Californian manufacturer Invecas presented for the first time a solution for transmitting 8K video (including HDCP 2.3) via the HDMI 2.1 standard. Invecas offers three integrated circuits (ICs) for TVs, set-top boxes, media players and sound bars.
They are capable of displaying 8K at 50/60Hz and 4K at 100/120Hz, have an Enhanced Audio Return Channel (eARC) which can transmit 3D sound from the TV to a connected AV receiver, Content Protection via HDCP 2.3 and Auto Low Latency Modes (ALLM) and Variable Refresh Rate (VRR) modes. In addition, static and dynamic HDR including Wide Color Gamut (WCG) can be displayed.
The VRR game mode enables a variable refresh rate, which depends on how many frames per second the graphics card can still produce in fluid movements. ALLM allows a source (such as a game console) to control all compatible components (such as an AV receiver or television) in the HDMI chain to automatically switch to the lowest latency mode.
Invecas demonstrates at CES 2019 the transmission of 8K 60Hz via Samsung's QLED 8K TVs, according to Invecas the data transmission rate via HDMI 2.1 is about 48 GBit/s - the extension box of Samsung's TVs is bridged and the video is output directly on the TVs.
