It is a one-wire bidirectional serial bus that is based on the CENELEC standard AV.link protocol to perform remote control functions. [46] CEC wiring is mandatory, although implementation of CEC in a product is optional. [5] :§8.1 It was defined in HDMI Specification 1.0 and updated in HDMI 1.2, HDMI 1.2a and HDMI 1.3a (which added timer and audio commands to the bus). [5] :§§CEC-1.2,CEC-1.3,CEC-3.1,CEC-5 USB to CEC adapters exist that allow a computer to control CEC-enabled devices. [47] [48] [49] [50] HDMI Ethernet and Audio Return Channel [ edit ] In its most recent versions, HDMI has caught up to DVI as both can now output 144hz at 1080p. In fact, HDMI is now considered the better option, as the cable simply supports more advanced technology than its dated counterpart. a b "HDMI 2.1 To Bring Robust Home Theater Experience". HD Guru.

Although no maximum length for an HDMI cable is specified, signal attenuation (dependent on the cable's construction quality and conducting materials) limits usable lengths in practice [70] [71] and certification is difficult to achieve for lengths beyond 13m. [72] HDMI 1.3 defines two cable categories: Category 1-certified cables, which have been tested at 74.25MHz (which would include resolutions such as 720p60 and 1080i60), and Category 2-certified cables, which have been tested at 340MHz (which would include resolutions such as 1080p60 and 4K30). [5] :§4.2.6 [63] [73] Category 1 HDMI cables are marketed as "Standard" and Category 2 HDMI cables as "High Speed". [3] This labeling guideline for HDMI cables went into effect on October 17, 2008. [74] [75] Category 1 and 2 cables can either meet the required parameter specifications for inter-pair skew, far-end crosstalk, attenuation and differential impedance, or they can meet the required non-equalized/equalized eye diagram requirements. [5] :§4.2.6 A cable of about 5 meters (16 feet) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081mm 2) conductors. [70] With better quality construction and materials, including 24AWG (0.205mm 2) conductors, an HDMI cable can reach lengths of up to 15 meters (49 feet). [70] Many HDMI cables under 5meters of length that were made before the HDMI 1.3 specification can work as Category 2 cables, but only Category 2-tested cables are guaranteed to work for Category 2 purposes. [76] MHz was the maximum TMDS character rate allowed in version 1.2a of the HDMI Specification and earlier. In version 1.3, the maximum allowed speed was increased to 340 MHz, and in version 2.0 it was increased to 600 MHz. These are only the maximum speeds permitted by the specification; individual devices may be limited to any speed within the maximum allowed. High-Definition Media Interface (HDMI) connects video and/or audio signals from a source device to an external device such as a monitor, soundbar or receiver. The DisplayPort audio/video interface was introduced in May 2006. Historically, HDMI Licensing LLC was publicly dismissive of DisplayPort's position in the industry, with its president stating in a 2009 interview that "there are certainly some PCs that have

The 48 Gbit/s bandwidth provided by HDMI 2.1 is enough for 8K resolution at approximately 50 Hz, with 8 bpc RGB or Y′C BC R 4:4:4 color. To achieve even higher formats, HDMI 2.1 can use Display Stream Compression with a compression ratio of up to 3∶1. Using DSC, formats up to 8K ( 7680 × 4320) 120 Hz or 10K ( 10240 × 4320) 100 Hz at 8 bpc RGB/4:4:4 are possible. Using Y′C BC R with 4:2:2 or 4:2:0 chroma subsampling in combination with DSC can allow for even higher formats.

HDMI 2.0 increases the maximum bandwidth to 18.0Gbit/s. [113] [114] [115] HDMI 2.0 uses TMDS encoding for video transmission like previous versions, giving it a maximum video bandwidth of 14.4Gbit/s. This enables HDMI 2.0 to carry 4K video at 60Hz with 24bit/px color depth. [113] [116] [117] Other features of HDMI 2.0 include support for the Rec. 2020 color space, up to 32 audio channels, up to 1536kHz audio sample frequency, dual video streams to multiple users on the same screen, up to four audio streams, 4:2:0 chroma subsampling, 25fps 3D formats, support for the 21:9 aspect ratio, dynamic synchronization of video and audio streams, the HE-AAC and DRA audio standards, improved 3D capability, and additional CEC functions.
