In an announcement today, the HDMI forum revealed the update to the format includes the following capabilities:

 

  • 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
  •  

    While some of these features were enabled in earlier specifications by individual manufacturers, the ratification by the working group should mean improved functionality throughout the sector. Thankfully, the updates is also fully backwards compatible with the HDMI 2.0a specification, with no need to purchase new cables to unlock the new features. Expect to see more about HDMI 2.0b at next month's CES event in Las Vegas.
