Video card - High-Definition Multimedia Interface (HDMI)

1 HDMI is a compact audio/video interface for transferring uncompressed video data

and compressed/uncompressed digital audio data from an HDMI-compliant

device ("the source device") to a compatible digital audio device, computer

monitor, video projector, or digital television. HDMI is a digital replacement

for existing analog video standards. HDMI supports copy protection through HDCP.

HDMI 1.4 - History

1 The HDMI Founders began development on HDMI 1.0 on April 16, 2002, with the goal of

creating an AV connector that was backward-compatible with DVI. At the time, DVI-HDCP (DVI with HDCP) and DVI-HDTV (DVI-HDCP using the CEA-861-B video standard) were

being used on HDTVs. HDMI 1.0 was designed to improve on DVI-HDTV by using a

smaller connector and adding support for audio, and enhanced support for YCbCr and

consumer electronics control functions.


HDMI 1.4 - History

1 The HDMI website contains a list of all

the ATCs.


HDMI 1.4 - History

1 In-Stat has estimated that 394 million HDMI devices will sell in 2009 and that all digital televisions by the end of 2009 would have at least one

HDMI input.


HDMI 1.4 - History

1 On January 28, 2008, In-Stat reported that shipments of HDMI were

expected to exceed those of DVI in 2008, driven primarily by the consumer electronics market.


HDMI 1.4 - History

1 In 2008, PC Magazine awarded a Technical Excellence Award in the Home Theater category for an innovation that

has changed the world to the CEC portion of the HDMI specification. Ten

companies were given a Technology and Engineering Emmy Award for their

development of HDMI by the National Academy of Television Arts and Sciences

on January 7, 2009.


HDMI 1.4 - History

1 From October 25, 2011, all development of the HDMI specification became the

responsibility of the newly created HDMI Forum.


HDMI 1.4 - History

1 On January 8, 2013, HDMI Licensing, LLC announced that that there were over 1,300 HDMI Adopters and that

over 3 billion HDMI devices had shipped since the launch of the HDMI standard. The day also marked the

10-year anniversary of the release of the first HDMI specification.


HDMI 1.4 - Specifications

1 An HDMI connection can either be single-link (type A/C) or dual-link

(type B) and can have a video pixel rate of 25MHz to 340MHz (for a

single-link connection) or 25MHz to 680MHz (for a dual-link connection)


HDMI 1.4 - Audio/video

1 On July 15, 2013, the CEA announced the publication of CEA-

861-F which is a standard that can be used by interfaces such as DVI,

HDMI, and LVDS



1 The color spaces that can be used by

HDMI are Rec



1 An example given on the HDMI website is that a TV that directly

receives a terrestrial/satellite broadcast, or has a video source built in, sends the audio upstream to the

AV receiver.



1 For example, a DVD player that sends an upscaled 720p/1080i

format via HDMI to an HDTV has no way to pass Closed captioning|Closed

Captioning data so that the HDTV can decode it, as there is Closed captioning#HDTV interoperability

issues|no line 21 VBI in that format.


HDMI 1.4 - Uncompressed video

1 Therefore usable uncompressed video out of HDMI is often called Clean HDMI.


HDMI 1.4 - Communication channel protocols

1 HDMI has three physically separate communication channels, which are

the DDC, TMDS and the optional CEC. HDMI 1.4 added ARC and HEC.


HDMI 1.4 - DDC

1 HDMI requires that the E-DDC support I²C standard mode speed

(100kbit/s) and allows optional support for fast mode speed

(400kbit/s).


HDMI 1.4 - DDC

1 The DDC channel is actively used for HDCP|High-bandwidth Digital Content Protection.


HDMI 1.4 - TMDS

1 Transition Minimized Differential Signaling (TMDS) on HDMI

interleaves video, audio and auxiliary data using three different packet

types, called the Video Data Period, the Data Island Period and the

Control Period


HDMI 1.4 - TMDS

1 Seven of the 15 Packet types described in the HDMI 1.3a

specifications deal with audio data, while the other 8 types deal with

auxiliary data


HDMI 1.4 - CEC

1 Consumer Electronics Control (CEC) is an HDMI feature designed to allow the user to command and control up-to 15 CEC-enabled devices, that are

connected through HDMI,


HDMI 1.4 - CEC

1 by using only one of their remote controls (for example by controlling a television set, set-top box, and DVD player using only the remote control

of the TV). CEC also allows for individual CEC-enabled devices to command and control each other

without user intervention.


HDMI 1.4 - CEC

1 It is a one-wire bidirectional serial communications|serial bus that is based on the

European Committee for Electrotechnical Standardization|CENELEC standard AV.link

protocol to perform remote control functions.http://www.quantumdata.com/pdf/CEC

_White_Paper.pdf CEC wiring is mandatory, although implementation of CEC in a product is optional. 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).


HDMI 1.4 - CEC

1 USB to CEC adapters exist that allow a computer to control CEC-enabled devices.


HDMI 1.4 - CEC

1 Trade names for CEC are Anynet+ (Samsung), Aquos Link (Sharp Corporation|Sharp), BRAVIA

Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi Ltd.|Hitachi), E-link (AOC International|AOC),

Kuro Link (Pioneer (company)|Pioneer), CE-Link and Regza Link (Toshiba), RIHD (Remote

Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG Electronics|LG), T-Link (ITT Corporation|ITT), HDAVI Control,

EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI

(Mitsubishi). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

HDMI 1.4 - ARC and HEC

1 HDMI 1.4 introduces two features called ARC (Audio Return Channel) and HEC (HDMI Ethernet Channel).

These features use two pins from the connector: a previously unused pin

and the hot plug detect pin.



1 ARC is an audio link meant to replace other cables between the TV and the

A/V receiver or speaker system



1 HEC provides a bidirectional Ethernet communication at 100Mbit/s. It also

goes by the name HEAC (HDMI Ethernet Audio Control). The Ethernet

physical layer|physical layer of the Ethernet implementation uses

attenuated 100BASE-TX type signals on a single twisted pair for both transmit and receive. from 2013


HDMI 1.4 - Compatibility with DVI

1 HDMI is backward compatibility|backward compatible with single-link Digital Visual Interface digital video (DVI-D or DVI-I, but not DVI-A). No

signal conversion is required when an adapter or asymmetric cable is used,

so there is no loss of video quality.



1 A further complication is that there is a small amount of display

equipment, such as some high-end home theater projectors, designed

with HDMI inputs but not HDCP-compliant.



1 Any DVI-to-HDMI adapter can function as an HDMI-to-DVI adapter (and vice-versa). Typically, the only

limitation is the gender of the adapter's connectors and the gender of the cables and sockets it is used

with.



1 Features specific to HDMI, such as remote-control and audio transport, are not available in devices that use legacy DVI-D signalling. However, many devices output HDMI over a DVI connector (e.g. Radeon R600|ATI 3000-series and GeForce 200 Series|NVIDIA GTX

200-series video cards), and some multimedia displays may accept HDMI (including audio) over a DVI input. Exact capabilities beyond

basic compatibility vary from product to product. Adapters are generally bi-directional.


HDMI 1.4 - Audio support

1 By 2010, nearly all HDMI-equipped sources (set-top and media-extender boxes, Blu-ray and DVD players, and PCs) provided separate analog audio outputs, and many HDMI-equipped

televisions supported alternate-audio input when sourcing video from an

HDMI input.


HDMI 1.4 - Audio support

1 There are consumer adapters available to place between a DVI

source and HDMI device which can insert a separate audio signal into an

HDMI TMDS data stream. DVI connectors on PC video cards have also been increasingly able to take

advantage of HDMI features such as audio output.


HDMI 1.4 - Content protection (HDCP)

1 High-bandwidth Digital Content Protection (HDCP) is a newer form of

Digital Rights Management. Intel created the original technology to

make sure that digital content followed the guidelines set by the Digital Content Protection group.



1 A simple example of this is several HDMI devices connected to an HDMI AV receiver that is connected to an

HDMI display.



1 Devices called HDCP strippers can remove the HDCP information from the video signal so the video can

play on non-HDCP-compliant displays, though a fair use and non-

disclosure form must usually be signed with a registering agency

before use.


HDMI 1.4 - Connectors

1 ;Type A: The plug (male) connector outside dimensions are 13.9mm ×

4.45mm, and the receptacle (female) connector inside dimensions are

14mm × 4.55mm. There are 19 pins, with bandwidth to support all SDTV,

EDTV and HDTV modes. It is electrically compatible with DVI-

D#Single-link DVI|single-link DVI-D.



1 ;Type B: This connector is 21.2mm × 4.45mm and has 29 pins, carrying six differential pairs

instead of three, for use with very high-resolution future displays such as Graphic display resolutions#WQUXGA|WQUXGA

(3,840×2,400). It is electrically compatible with DVI-D#Dual-link DVI|dual-link DVI-D, but

has not yet been used in any products. However, the use of the extra three differential

pairs is reserved as of 1.3 specification.



1 ;Type C: This Mini connector is smaller than the type A plug,

measuring 10.42mm × 2.42mm but has the same 19-pin configuration



1 ;Type D: This Micro connector shrinks the connector size to something

resembling a USB#Mini and Micro|micro-USB connector., measuring

only 6.4mm × 2.8mm For comparison, a micro-USB connector is 6.85mm × 1.8mm and a USB Type A connector is 11.5mm × 4.5mm. It keeps the standard 19 pins of types A and C, but the pin assignment is

different from both.https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html


1 ;Type E: The Automotive Connection System has a locking tab to keep the cable from vibrating loose and a shell

to help prevent moisture and dirt from interfering with the signals. A

relay connector is available for connecting standard consumer cables to the automotive type.


HDMI 1.4 - Cables

1 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.


HDMI 1.4 - Cables

1 * Standard HDMI Cable – up to 1080i

and 720p


HDMI 1.4 - Cables

1 * Automotive HDMI Cable


HDMI 1.4 - Cables

1 * High Speed HDMI Cable – 1080p, 4K resolution|4K, 3D television|3D and deep

color


HDMI 1.4 - Cables

1 An HDMI cable is usually composed of four shielded twisted pairs, with

impedance of the order of 100ohm|Ω, plus several separate conductors.


HDMI 1.4 - Extenders

1 HDMI extenders that are based on dual Category 5 cable|Category

5/Category 6 cable can extend HDMI to 250meters (820ft), while HDMI

extenders based on optical fiber can extend HDMI to 300meters (980ft).


HDMI 1.4 - Cost

1 An example is that an HDMI cable sold directly to consumers is paid for by the cable manufacturer but if the cable manufacturer sells the HDMI cable to a HDTV manufacturer that includes it with an HDTV subject to

the royalty then the HDTV manufacturer pays only the royalty

on the HDTV.


HDMI 1.4 - Versions

1 Non-cable HDMI products starting on January 1, 2012 will no longer be

allowed to reference the HDMI number and will be required to state

which features of the HDMI specification the product supports.


HDMI 1.4 - Version 1.0 to 1.2

1 HDMI 1.2a was released on December 14, 2005 and fully specifies Consumer Electronic

Control (CEC) features, command sets and CEC compliance tests.


HDMI 1.4 - Version 1.3

1 It optionally supports deep color, with 30-bit, 36-bit and 48-bit xvYCC, sRGB, or YCbCr, compared to True

Color|24-bit sRGB or YCbCr in previous HDMI versions



1 It also added support for optionally streaming SACD in its bitstream DST

format rather than uncompressed raw DSD like from HDMI 1.2 onwards.



1 HDMI 1.3b, 1.3b1 and 1.3c were released on March 26, 2007,

November 9, 2007, and August 25, 2008 respectively. They do not introduce differences on HDMI

features, functions, or performance, but only describe testing for products based on the HDMI 1.3a specification

regarding HDMI compliance (1.3b



1 High Speed HDMI 1.3 cables can support all HDMI 1.4 features except for the HDMI

Ethernet Channel.



1 HDMI 1.4a requires that 3D displays support the frame packing 3D format

at either 720p50 and 1080p24 or 720p60 and 1080p24, side-by-side

horizontal at either 1080i50 or 1080i60, and top-and-bottom at either 720p50 and 1080p24 or

720p60 and 1080p24.



1 HDMI 1.4b was released on October 11, 2011. One of the new features is

that it adds support to 3D 1080p video at 120Hz -allowing frame

packing 3D format at 1080p60 per Eye (120Hz total) . All future versions

of the HDMI specification will be made by the HDMI Forum that was

created on October 25, 2011.



1 Other features of HDMI 2.0 include support for 4:2:0 chroma subsampling, support for 25 fps 3D formats, improved 3D capability,

support for up to 32 channels of audio, support for up to 1536kHz audio, support for

up to 4 audio streams, support for 21:9 aspect ratio, support for the High-Efficiency

Advanced Audio Coding|HE-AAC and Dynamic Resolution Adaptation|DRA audio

standards, dynamic auto lip-sync, and additional CEC functions.


HDMI 1.4 - Version comparison

1 Note that a given product may choose to implement a subset of the given HDMI version. Certain features

such as deep color and xvYCC support are optional.


HDMI 1.4 - Blu-ray Disc and HD DVD players

1 Blu-ray Disc and HD DVD, introduced in 2006, offer high-fidelity audio features that require HDMI for best results. HDMI 1.3 can transport Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master Audio bitstreams in compressed form.

This capability allows for an AV receiver with the necessary decoder to decode the compressed

audio stream. The Blu-ray specification does not support video encoded with either deep color or xvYCC; thus, HDMI 1.0 can transfer Blu-ray discs

at full video quality.


HDMI 1.4 - Blu-ray Disc and HD DVD players

1 Some low-cost AV receivers, such as the Onkyo TX-SR506, do not support audio processing over HDMI and are

labelled as HDMI pass through devices.


HDMI 1.4 - Digital cameras and camcorders

1 As of 2012, most consumer camcorders, as well as many digital cameras, are equipped with a mini-HDMI connector (type C connector).


HDMI 1.4 - Personal computers

1 Linux can support 8-channel LPCM audio over HDMI if the video card has the necessary hardware and supports

the Advanced Linux Sound Architecture (ALSA)



1 Even with an HDMI output, a computer may not support High-

bandwidth Digital Content Protection|HDCP, Microsoft's Protected Video

Path, or Microsoft's Protected Audio Path



1 The Asus Xonar HDAV1.3 became the first HDMI sound card that supported the Protected Audio Path and could both bitstream and decode lossless audio (Dolby TrueHD and DTS-HD MA), although bitstreaming is only

available if using the ArcSoft TotalMedia Theatre software. It has an HDMI 1.3 input/output, and Asus

says that it can work with most video cards on the market.



1 The AMD Radeon HD 7000 Series supports HDMI

1 On August 27, 2012, Asus announced a new monitor which can support its native resolution of 2560×1440 via

HDMI 1.4.


HDMI 1.4 - Tablet computers

1 Most new laptops and desktops now have built in HDMI as well.


HDMI 1.4 - Mobile phones

1 Many recent mobile phones support output of HDMI video via either a micro-HDMI connector or Mobile High-definition Link|MHL output.


HDMI 1.4 - Legacy compatibility

1 The passive cables are only useful if you have a device that is generating or expecting HDMI signals on a VGA

connector, or VGA signals on an HDMI connector; this is a non-

standard feature, not supported by most devices.


HDMI 1.4 - Relationship with DisplayPort

1 DisplayPort ports can be made so that they are compatible with single-link Digital Visual Interface|DVI and

HDMI 1.4


HDMI 1.4 - Relationship with DisplayPort

1 HDMI has a few advantages over DisplayPort, such as support for

#CEC|Consumer Electronics Control (CEC) signals, and electrical

compatibility with DVI (though practically limited to single-link DVI

rates).


HDMI 1.4 - Relationship with MHL

1 Mobile High-definition Link (MHL) is an Technical standard|industry standard for a mobile audio/video interface for directly

connecting mobile phones and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and displays.

MHL is being developed by the 'MHL Consortium', a consortium of developers of

mobile devices. Many of the companies behind MHL are also the ones behind HDMI. MHL is an evolution of HDMI rather than a new standard.



1 MHL is basically an HDMI stream that has three logical channels

multiplexed into a single physical one. Each logical channel represents a data channel in HDMI. Overall, an

MHL cable only needs five wires instead of the nineteen used in HDMI.



1 * Power is transmitted through the cable. Typical cases include the TV charging the mobile device and the mobile device powering an active

MHL to HDMI dongle.



1 * Uses a single, thin cable to connect the mobile device to the TV

compared to HDMI. Typical MHL cables are 1.5m long.



1 * Video resolution limited to 1080p uncompressed 4:2:2 HD video

(PacketVideo) or 720p 4:4:4 HD video. MHL 2.0 supports 1080p at

60FPS.



1 * 8 channel (e.g., 7.1 surround sound)

uncompressed audio.



1 * Supports High-bandwidth Digital Content Protection

(HDCP).



1 * Typical MHL connector is micro USB, a typical connector already

found in many mobile devices. The same micro USB connector can be

used to charge the device, to establish data communication with a

computer and to transfer uncompressed video.


Digital Visual Interface - DVI and HDMI compatibility

1 HDMI is a newer digital audio/video interface developed and promoted by

the consumer electronics industry. DVI and HDMI have the same

electrical specifications for their TMDS and VESA/DDC links. However,

HDMI and DVI differ in several key ways:



1 * DVI is limited to the RGB color range (0-255). HDMI supports RGB, but also supports YCbCr 4:4:4 and

YCbCr 4:2:2. These ranges are widely used outside of (beyond) computer

graphics, color rendering.



1 * HDMI supports the transport of packets, needed for digital audio, in addition to digital video. An HDMI source differentiates between a legacy DVI display and an HDMI-capable display by reading the

display's EDID block.



1 So, DVI-D devices output HDMI signals, many including audio,

(examples: Radeon R600|ATI 3000-series and GeForce 200 Series|

NVIDIA GTX 200-series video cards), and some multimedia displays input that HDMI signal, including audio, by

using a DVI to HDMI adapter



1 Effectively, HDCP compatibility between source and destination

devices is completely subject to the manufacturer's specifications for each, respective HDMI capable

device.


Mobile High-Definition Link - Standard Micro-USB-to-HDMI adapter (five-pin)

1 The first implementations use the most popular mobile connection

(micro USB) and the most popular TV connection (HDMI). Other than the physical connectors, USB and HDMI technology are not being used. It is exclusively MHL signaling through the connectors and over the cable.


Mobile High-Definition Link - Samsung Micro-USB-to-HDMI adapter and tip (eleven-pin)

1 Samsung 2.0 smart adapter does require external power and is able to work with HDMI

TVs.


Graphics card - High-Definition Multimedia Interface (HDMI)

1 HDMI is a compact audio/video interface for transferring uncompressed video data and

compressed/uncompressed digital Uncompressed audio|audio data from an HDMI-

compliant device (the source device) to a compatible digital audio device, visual display

unit|computer monitor, video projector, or digital television. HDMI is a digital replacement

for existing analog video standards. HDMI supports copy protection through High-

Bandwidth Digital Content Protection|HDCP.

Uncompressed video - HDMI 1.3a Specifications

1 Detailed timing is found in CEA-861-D or a later version of CEA-861 for the following video format timings.



1 Cameras mostly use the progressive segmented frame format: for

example a 25p/30p progressive scan is transported in a 50i/60i interlaced

format respectively, but with identical information: No

deinterlacing should be used.



1 There are three different pixel encodings that may be sent across

an HDMI cable: YCbCr Chroma subsampling#Types of subsampling|4:4:4 (chroma subsampling), YCbCr

4:2:2 and RGB 4:4:4.



1 There are four color depths supported: 24-, 30-, 36- and 48-bits per

pixel.


DVI-D - DVI and HDMI compatibility

1 * DVI is limited to the RGB color range (0–255). HDMI supports RGB, but also supports YCbCr 4:4:4 and

1 It has the further advantage of higher quality due to no motion blur (no motion compensation) and no

compression artifacts.



1 Currently there is no standardized uncompressed video file format except for HDMI, which uses the

YCbCr and RGB formats listed below. This makes it necessary to store it best with a related description file

equipment, such as some high-end home theater projectors, designed

with HDMI inputs but not HDCP-compliant.


HDMI cable - Audio

1 By 2010, nearly all HDMI-equipped sources (set-top and media-extender boxes, Blu-ray and DVD players, and PCs) provided separate analog audio outputs, and many HDMI-equipped

televisions were equipped for alternate-audio input when sourcing

video from an HDMI input.


HDMI cable - Connectors

1 ;Type D: This Micro connector shrinks the connector size to something

resembling a USB#Mini and Micro|micro-USB connector, measuring

only 6.4mm × 2.8mm For comparison, a micro-USB connector is 6.85mm × 1.8mm and a USB Type A connector is 11.5mm × 4.5mm. It keeps the standard 19 pins of types A and C, but the pin assignment is

different from both.https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

available starting in the second half to 2015. It is anticipated that such Blu-ray UHD players will be required

to include a HDMI 2.0 output supporting HDCP 2.2.



1 As of this update, among the major manufacturers of AV receivers only

Onkyo/Integra offers such AV Receivers that support both HDMI 2.0

and HDCP 2.2 as will be needed to support certain of the high quality 4K/UHD video sources, such as the upcoming Blu-ray 4K/UHD players.


HDMI cable - Personal computers

1 Even with an HDMI output, a computer may not be able to

produce signals that implement High-bandwidth Digital Content Protection|

HDCP, Microsoft's Protected Video Path, or Microsoft's Protected Audio

Path



1 The Asus Xonar HDAV1.3 became the first HDMI sound card that

implemented the Protected Audio Path and could both bitstream and

decode lossless audio (Dolby TrueHD and DTS-HD MA), although

bitstreaming is only available if using the ArcSoft TotalMedia Theatre software. It has an HDMI 1.3

input/output, and Asus says that it can work with most video cards on

the market.
