HDMI Cable – All Important Info And Innovations


Here you will find all the important information about the HDMI connection:


High Definition Multimedia Interface – Or HDMI For Short

An interface newly developed in 2003 for the transmission of audio and video signals. It was developed by the industry specifically for home entertainment and has been available in version 1.3 since June 23, 2006. Since May 2009 it has been upgraded to version 1.4.

As more and more digital components are used in the home entertainment sector just mentioned, and as the useful content is also increasingly available in digital form (DVD, DVB), the weaknesses of the previously unavoidable digital-to-analog and analog-to-digital conversions became increasingly clear.

HDMI thus heralds a new, fully digital, age in which audio and video signals are no longer transported to the system via the usual analog route (coaxial cable, Scart).

This New Technology Has Many Advantages

The HDMI standard is consistently supported by most consumer electronics manufacturers.

One HDMI connector combines the transmission of picture and sound, which means you only need one cable instead of three (Scart, Cinch (L/R).

Since HDMI works without any compression methods, you don’t have to sacrifice quality.

If, for example, you have a DVD player with an HDMI interface as well as a plasma TV with fully digital image processing, it is no longer necessary to convert the digital data into analog data, which means that there is no longer any loss of quality (during conversion) here either.

Thanks to the high-frequency reproduction capability for audio data (up to 192 kHz) and word widths on eight channels with up to 48 bits, as well as the good bandwidth for video transmission (340 MHz), all new image and sound formats introduced in the home theater world (e.g. HDTV) can be reproduced without loss of quality. Additionally, the new audio formats Dolby Digital Plus, Dolby True-HD as well as DTS-HD Master have been included.

Other Advantages:

In relation to the previously mentioned advantage of HDMI, another is the future-proofing, because HDMI uses only half of its “power” even when playing and an HDTV or Blu-Ray transmission.

No more fear of motion-blurred images (of course, a corresponding flat-screen TV is also a prerequisite)! HDMI transfers the image material at a speed of up to 8.16 GB per second (HDMI 1.3 connector type A and C).

HDMI is based on DVI and is completely backward compatible, which means you can easily connect an HDMI-capable player to your DLP projector with a DVI interface (there are corresponding DVI-HDMI adapters).

Control any of your HDMI devices with one universal remote control! HDMI supports AV.link and CEC protocols.

HDMI can easily handle cable lengths of up to 20 meters. Special cables with fiberglass also allow laying 100 meters, but at the expense of maximum data transmission, so you won’t see 1080p/24, for example, but only 1080i or less.

Since There Are Different HDMI Specifications, There Are Also Different Connector Types:

Two types of connectors have been developed for HDMI 1.1 and 1.2: Type A and Type B,
approximately 4.5 x 13/21 mm cross-section.

Connector type C has been developed for HDMI 1.3, with a cross-section of approximately 2.5 x 10.5 mm.

Type A and C are based on a single-link connection, with three TMDS lines available, and Type B allows double the data rate by doubling from three to six TMDS lines.

All Well And Good, But Is It Worth Switching To HDMI Now?

Yes! HDMI has taken advantage of its great national and international “survival chances” and is therefore now part of the standard equipment of every Blu-Ray player, DVD player, AV receiver, TV, console, PC, projector, etc, and not least because of the 100% DVI support. So that the audiophiles also get their taste, HDMI can also transmit SACDs since version 1.2 in addition to DVD-Audio (HDMI 1.1).

At the beginning of the 2009 calendar year, the specifications for the upcoming version of the HDMI 1.3 successor were announced. This process, undertaken by the HDMI Licensing behind it, comes a good two and a half years after the announcement of the 1.3b standard.

The currently latest version has officially been called “HDMI 1.4” since May 2009.
There are some innovations in this version, e.g. the maximum transferable picture format has increased to 2160p/30 Hz, which of course also includes downward compatibility with 1440p/120 Hz as well as 1080p/60 Hz.


The color space has also been expanded, as sYCC601, Adobe RGB, and Adobe YCC601 have now been added to the usual Deep Color, RGB/YUV, etc. The connector types are supplemented by a Micro HDMI Connector and an Automotive Connection System. In contrast to the previous version 1.3 a, b, and c, no bug fixing has been done in version 1.4, but new features have been added.

For example, a 3D playback function (which was presented by Panasonic at the IFA 2009) and the HDMI Ethernet and Audio Return Channel. Since version 1.3, the data rate has remained constant at 8.16 Gbit/s (type A+C, 19-pin). Nothing has changed in the audio formats either – why should it? All common sound formats like DTS-HD Master, Dolby TrueHD, etc. are still compatible with version 1.4.

The Following Specification Also Caused Astonishment At The Presentation Of The New Version:

The developers have turned the speed screw. After all, the maximum speed for a single-link HDMI connection has already been increased from 165 MHz (4.95 GBit/s) to 340 MHz (10.2 GBit/s) – a data rate that current video applications do not utilize at all. Now the maximum bit rate has been increased again for 4K and 3D applications.

Specifically, this is the ability to display movies from high-resolution video cameras, such as the 65 mm 5 PERF, with a maximum resolution of 4096 horizontal image lines, as well as better exposure of the source material.

Critics see the interval-based updating of the standard as their annoyance that a home theater chain will not remain up-to-date for long. For example, everything from the TV to the Blu-Ray player to the AV receiver (not to mention the HDMI cable) has to be replaced every three years if you want to be up to date â?? perhaps politicians should think about a kind of “home theater scrappage premium?”!

Can Digital Copies Be Created Via The HDMI Interface?

No, at least not for the time being! HDMI has the new copy protection HDCP (see HDCP in the home theater encyclopedia). HDCP is only decrypted in the receiving (usually) picture-reproducing component and recording devices such as a hard disk recorder do not have a corresponding HDCP decryption algorithm to this day.
By the way: Who now thinks that he can modify his device: This is punishable since the beginning of 2003!


However, Pioneer presented the first Blu-Ray player that includes the “Managed Copy” function at the CEDIA trade show in September 2009. This allows at least legal copies of a Blu-Ray disc to be made. However, the idea of the function is not new, because it has already been part of the copy protection AACS since 2006. In the sample, an inserted Blu-Ray disc could be copied to a 1 terabyte hard drive at a maximum of four times the speed, including menus and extras.

Accordingly, the sample movie “Bold” was copied in just under 20 minutes. The presentation also clearly shows that not every Blu-ray disc can be copied. Rather, the Pioneer player first contacts the server of the studio in question via its broadband connection to the Internet to ask whether a managed copy can be made of the film.

The video also shows that the copy in the example is only allowed against payment of a sum of money. Pioneer does not provide any information about how much a copy will ultimately cost. The copied movie can then be played in HD quality from the hard drive without having to insert the source disc. It is still unclear whether the player, which supports the DLNA streaming standard, can also send this content to clients in the local network.

New logos For HDMI From 01.01.2012

As of Jan. 1, 2012, manufacturers of HDMI products may only advertise with the new logos specified by HDMI Licensing LLC. With this measure, the organization wants to create more clarity, since with the introduction of HDMI 1.4 are now five different types of HDMI cables on the market.


Corresponding cables and devices advertise with version numbers such as HDMI 1.3, 1.3a or, more recently, 1.4, which is of little informative value to most customers and leads to the first having to laboriously find out about the functions of the HDMI versions.

HDMI Licensing LLC has now divided the HDMI cables into five categories, the corresponding logos indicate the different functions: In addition to the “Standard HDMI Cable”, there is the variant with Ethernet “Standard HDMI Cable with Ethernet”. The “Standard Automotive HDMI Cable” is suitable for installation in vehicles. The types “High-Speed HDMI Cable” and “High-Speed HDMI Cable with Ethernet” support the higher data rates introduced from HDMI specification 1.4.


The new logos for these are as follows:

Neue HDMI-Logos ab 2012

Februar 2010:

HDMI Licensing LLC announced on Feb. 6, 2010, that HDMI version 1.4a was already in the works, although the basic version 1.4 is hardly used productively at present. The background to this announcement was a meeting of the consortium in which industry representatives had called for improvements.

According to HDMI Licensing LLC, the specification is to be adapted to the extent that 3D TV receivers already available will also officially comply with the standard, even if they only support one of the optional 3D transmission methods. No further details were given. The revised HDMI 1.4a specification is expected to be finalized shortly.

In addition, the HDMI Consortium has published the part of the HDMI 1.4 specification that relates to stereoscopic images. Among other things, this describes the “frame packing” process, which shows how the images for both eyes are transmitted together in one frame.

Accordingly, the image for the left eye is located in the upper part of the frame and the right in the lower. This creates a 3D image with a total resolution of 1,920 x 2,205 pixels, which contains two images of 1,920 x 1,080 pixels each, separated by a space of 45 lines.


HDMI Licensing LLC CEO Steve Venuti explained that the consortium is aware of the importance of uniform 3D formats for movies, games, and TV content. He said they published the specifications so that companies not participating in the HDMI Adopter Agreement could access them. “The adoption of 3D in the mass market is gaining momentum and HDMI is ready to support this significant market development”, Venuti said.
