Mhl Specification Version 1.2 Pdf
Production of consumer HDMI products started in late 2003. In Europe, either DVI-HDCP or HDMI is included in the HD ready in-store labeling specification for TV sets for HDTV, formulated by EICTA with SES Astra in 2005. HDMI began to appear on consumer HDTVs in 2004 and camcorders and digital still cameras in 2006. As of January 2021[update], nearly 10 billion HDMI devices have been sold.

According to In-Stat, the number of HDMI devices sold was 5 million in 2004, 17.4 million in 2005, 63 million in 2006, and 143 million in 2007. HDMI has become the de facto standard for HDTVs, and according to In-Stat, around 90% of digital televisions in 2007 included HDMI. In-Stat has estimated that 229 million HDMI devices were sold in 2008. On April 8, 2008 there were over 850 consumer electronics and PC companies that had adopted the HDMI specification (HDMI adopters). On January 7, 2009, HDMI Licensing, LLC announced that HDMI had reached an installed base of over 600 million HDMI devices. In-Stat has estimated that 394 million HDMI devices would sell in 2009 and that all digital televisions by the end of 2009 would have at least one HDMI input.
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.
On October 25, 2011, the HDMI Forum was established by the HDMI founders to create an open organization so that interested companies can participate in the development of the HDMI specification. All members of the HDMI Forum have equal voting rights, may participate in the Technical Working Group, and if elected can be on the Board of Directors. There is no limit to the number of companies allowed in the HDMI Forum though companies must pay an annual fee of US$15,000 with an additional annual fee of $5,000 for those companies that serve on the Board of Directors. The Board of Directors is made up of 11 companies who are elected every 2 years by a general vote of HDMI Forum members. All future development of the HDMI specification take place in the HDMI Forum and are built upon the HDMI 1.4b specification. Also on the same day HDMI Licensing, LLC announced that there were over 1,100 HDMI adopters and that over 2 billion HDMI-enabled products had shipped since the launch of the HDMI standard. From October 25, 2011, all development of the HDMI specification became the responsibility of the newly created HDMI Forum.
On January 8, 2013, HDMI Licensing, LLC announced 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 10th anniversary of the release of the first HDMI specification.
A new certification program was introduced in October 2015 to certify that cables work at the 18 Gbit/s maximum bandwidth of the HDMI 2.0 specification. In addition to expanding the set of cable testing requirements, the certification program introduces an EMI test to ensure cables minimize interference with wireless signals. These cables are marked with an anti-counterfeiting authentication label and are defined as:
In conjunction with the HDMI 2.1 specification, a third category of cable was announced on January 4, 2017, called "48G". Also known as Category 3 HDMI or "Ultra High Speed" HDMI, the cable is designed to support the 48 Gbit/s bandwidth of HDMI 2.1, supporting 4K, 5K, 8K and 10K at 120 Hz. The cable is backwards compatible with the earlier HDMI devices, using existing HDMI type A, C and D connectors, and includes HDMI Ethernet.
The HDMI specification is not an open standard; manufacturers need to be licensed by HDMI LA in order to implement HDMI in any product or component. Companies that are licensed by HDMI LA are known as HDMI Adopters.
While earlier versions of HDMI specs are available to the public for download, only adopters have access to the latest standards (HDMI 1.4b/2.1). Only adopters have access to the compliance test specification (CTS) that is used for compliance and certification. Compliance testing is required before any HDMI product can be legally sold.
The USB 3.1 Type-C connector is an emerging standard that replaces legacy video connectors such as mDP, Thunderbolt, HDMI, and VGA in mobile devices. USB-C connectors can transmit DisplayPort video to docks and displays using standard USB Type-C cables or Type-C to DisplayPort cables and adapters; USB-C also supports HDMI adapters that actively convert from DisplayPort to HDMI 1.4 or 2.0. DisplayPort Alternate Mode for USB Type-C specification was published in 2015. USB Type-C chipsets are not required to include Dual-mode transmitters and only support DisplayPort LVDS protocol, so passive DP-HDMI adapters do not work with Type-C sources.
The TekExpress MHL Advanced Analysis and Compliance software gives you the tools to easily run Mobile High-definition Link (MHL) tests in accordance with MHL compliance test specifications 1.X, 2.0, 1.3 / 2.1 and 3.3. It provides a complete and reliable solution for quick testing.
The MHL 1.1/1.2/1.3/2.0/2.1/3.3 specifications support MHL, which enables mobile devices to transmit uncompressed audio/video to an HDTV or receiver with HD capability. Option MHD and MHD3 Advanced Analysis and Compliance Test Software meets the MHL 1.1/1.2/1.3/2.0/2.1/3.3 CTS specification and automates a comprehensive range of tests, enabling unprecedented efficiency with reliable results. TEK-PGY-MHL-PA-SW MHL Protocol Analyzer Software supports up to 1.1/1.2/2.0 and 1.3/2.1 CTS specification.
The HDMI interface allows a port to send high-resolution digital video, theatre-quality sound and device commands through an HDMI connector and down a single HDMI cord, each designed to support a video resolution and features in the HDMI specification.
There are also different types of HDMI cable (see the chart below). Not all cables use the logo but the cable specifications should indicate whether it is Standard, High Speed, Premium High Speed or Ultra High Speed. If the type is not indicated, assume Standard.
The initial HDMI specification provided support for 24-bit Color Depth (8-bits per color x 3 colors RGB). HDMI 1.3 introduced Deep Color, which added support for 30-bit, 36-bit and 48-bit color depths. It's worth keeping in mind that the human eye can only distinguish around 10 million different color, so 24-bit color is adequate for most situations. 350c69d7ab
