HDMI 2.0b, which is backwards compatible with earlier versions of the HDMI specification, is the most recent update of the HDMI specification. It also enables key enhancements to support market requirements for enhancing the consumer video and audio experience.
What are the key advanced features enabled by HDMI 2.0b?
- Enables transmission of High Dynamic Range (HDR) video
- Bandwidth up to 18Gbps
- 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution
- Up to 32 audio channels for a multi-dimensional immersive audio experience
- Up to 1536kHz audio sample frequency for the highest audio fidelity
- Simultaneous delivery of dual video streams to multiple users on the same screen
- Simultaneous delivery of multi-stream audio to multiple users (Up to 4)
- Support for the wide angle theatrical 21:9 video aspect ratio
- Dynamic synchronization of video and audio streams
- CEC extensions provide more expanded command and control of consumer electronics devices through a single control point
HDMI 2.0b does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth.
NOTICE: Previously, HDMI Specification Version 2.0b (HDMI 2.0b) only supported HDR (High Dynamic Range) video transport in the SMPTE ST 2084 EOTF (as applied in the media profile commonly known as HDR10), by referencing the CTA861.3 specification. The Consumer Technology Association (CTA) has recently notified the HDMI Forum of the adoption of a new version of the CTA-861 Specification, CTA-861-G. This new version provides additional support for HDR Video transport by including (among others) an extension to the static metadata signaling to include the HLG (Hybrid Log Gamma) EOTF. The HDMI Forum has assessed the applicability of the CTA-861-G Specification to HDMI 2.0b. The HDMI Forum has confirmed that the extension of the static metadata signaling to include HLG can be utilized under the existing HDMI 2.0b Specification. This means that HLG Video Transport functionality may be implemented on HDMI 2.0b compliant devices.
