uncompressed high definition video, up to 8 channels of audio, and control signals, over a single
cable.
●
HDMI 1.3:
released on June 22 2006, and increased the maximum TMDS clock to 340 MHz (10.2 Gbit/s).
Support resolution 1920 × 1080 at 120 Hz or 2560 × 1440 at 60 Hz). It added support for 10 bpc, 12 bpc,
and 16 bpc color depth (30, 36, and 48 bit/px), called deep color.
● HDMI 1.4 :
released on June 5, 2009, added support for 4096 × 2160 at 24 Hz, 3840 × 2160 at 24, 25,
and 30 Hz, and 1920 × 1080 at 120 Hz. Compared to HDMI 1.3, 3 more features added which are HDMI
Ethernet Channel (HEC) , audio return channel (ARC),3D Over HDMI, a new Micro HDMI Connector, an
expanded set of color spaces.
●
HDMI 2.0
,
released on September 4, 2013 increases the maximum bandwidth to 18.0 Gbit/s. Other
features of HDMI 2.0 include up to 32 audio channels, up to 1536 kHz audio sample frequency,
the HE-AAC and DRA audio standards, improved 3D capability, and additional CEC functions.
●
HDMI 2.0a:
was released on April 8, 2015, and added support for High Dynamic Range (HDR)
video with static metadata.
●
HDMI 2.0b:
was released March, 2016, support for HDR Video transport and extends the static
metadata signaling to include
(HLG).
●
HDMI 2.1
: released on November 28, 2017. It adds support for higher resolutions and higher refresh
rates, Dynamic HDR including 4K 120 Hz and
120 Hz.
●
DisplayPort:
A VESA standard interface primarily for video, but also for audio, USB and other data.
DisplayPort (orDP) is backwards compatible with HDMI, DVI and VGA.
●
DP 1.1:
was ratified on 2 April 2007, and version 1.1a was ratified on 11 January 2008. DisplayPort 1.1
allow a maximum bandwidth of 10.8 Gbit/s (8.64 Gbit/s data rate) over a standard 4-lane main link,
enough to support 1920x1080@60Hz
●
DP 1.2:
introduced on 7 January 2010, effective bandwidth to 17.28 Gbit/s support increased
resolutions, higher refresh rates, and greater color depth, maximum resolution 3840 × 2160@60Hz
● DP 1.4:
publish on 1 Mar, 2016.overall transmission bandwidth 32.4 Gbit/s ,DisplayPort 1.4 adds
support for Display Stream Compression 1.2 (DSC), DSC is a "visually lossless" encoding technique with
up to a 3:1 compression ratio. Using DSC with HBR3 transmission rates, DisplayPort 1.4 can support 8K
UHD (7680 × 4320) at 60 Hz or 4K UHD (3840 × 2160) at 120 Hz with 30 bit/px RGB color and HDR. 4K at
60 Hz 30 bit/px RGB/HDR can be achieved without the need for DSC.
●Multi-mode Fiber:
Fibers that support many propagation paths or transverse modes are
called multi-mode fibers, generally have a wider core diameter and are used for short-distance
