Data transfer rate significantly increased in HDMI 2.0b

Standard HDMI digital video transmission is firmly won its place in TVs, projectors and other home and professional video equipment. Although DisplayPort requires no royalties and offers better performance HDMI to oust him is unlikely in the coming years. More recently, the organization responsible for the development of the HDMI standard, published specification version 2.0b. Compared with the 2.0a version of the new standard has been expanded opportunities for the transfer of video with high dynamic range (HDR).
 
HDMI 2.0b standard supports such video in standard HDR10 described more in version 2.0a, and the HLG standard (Hybrid Log-Gamma), developed by the BBC and NHK corporations. The maximum data transfer rate increased to 18 Gbit / s, that allows you to output video in 2160p resolution at 60 Hz. The video stream may be accompanied by 32 audio channels with a maximum aggregate bandwidth of 36.8 Mbit / s.
 
Supports simultaneous synchronous transmission of two video streams for multiple audiences with separate screens. Improved support for 21: 9, considerably augmented the HDMI CEC protocol, allows you to manage all devices from a single remote control. What is particularly nice, HDMI 2.0b cables do not require replacement – should be fine already available. Yet it must be remembered that the standard DisplayPort has already markedly leave ahead, offering bandwidth of 32.4 Gb / s, which is much higher than 18 Gbit / s in HDMI 2.0b.
