HDMI explained

Dynamic HDR simply means the dynamic range can be set on a per-scene basis (or frame-by-frame in the case of high-end TVs). Enhanced Audio Return Channel (eARC) was introduced in HDMI 2.1 and provides support for higher-quality audio bandwidth and speed. eARC requires a High Speed HDMI cable with Ethernet or an Ultra High Speed HDMI cable. eARC is not backwards compatible with ARC but some products may support both eARC and ARC. A wireless HDMI extender is much easier to install, can be easily relocated and can broadcast a high-resolution video signal to multiple receivers. Note: In-wall HDMI cables have a CL2 or CL3 rating. This means that the cable jacket is fire resistant and suitable to low-voltage in-wall applications. HDMI means High-Definition Multimedia Interface, a standard for simultaneously transmitting digital video and audio from a source, such as a computer or TV cable box, to a computer monitor, TV or projector. * Higher refresh rates are possible using Display Stream Compression (DSC). ** HDMI encodes data and uses some of the available bandwidth to ensure the integrity of the signal. This means that the actual data rate is something less than the maximum transmission rate.

Other formats are optional, with HDMI allowing up to 8 channels of uncompressed audio at sample sizes of 16 bits, 20 bits, or 24 bits, with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, or 192 kHz. HDMI also carries any IEC 61937-compliant compressed audio stream, such as Dolby Digital and DTS, and up to 8 channels of one-bit DSD audio (used on Super Audio CDs) at rates up to four times that of Super Audio CD. HDMI 1.2 was released on August 8, 2005, and added the option of One Bit Audio, used on Super Audio CDs, at up to 8 channels. To make HDMI more suitable for use on PC devices, version 1.2 also removed the requirement that only explicitly supported formats be used. Previously, the similar DisplayPort Alternate Mode could be used to connect to HDMI displays from USB Type-C sources, but where in that case active adapters were required to convert from DisplayPort to HDMI, HDMI Alternate Mode connects to the display natively. The Alternate Mode reconfigures the four SuperSpeed differential pairs present in USB-C to carry the three HDMI TMDS channels and the clock signal. Version 3.0 increased the bandwidth to 6 Gbit/s to support Ultra HD (3840 × 2160) 30 Hz video, and also changed from being frame-based, like HDMI, to packet-based. The fourth version, superMHL, increased bandwidth by operating over multiple TMDS differential pairs (up to a total of six) allowing a maximum of 36 Gbit/s. The six lanes are supported over a reversible 32-pin superMHL connector, while four lanes are supported over USB-C Alternate Mode (only a single lane is supported over micro-USB/HDMI).

HDMI Technology: Specifications and Programs

Almost 14 billion devices enabled with HDMI® technology have shipped since the first HDMI specification was released in December 2002. The latest HDMI 2.2 Specification continues to enable the development of new product categories and innovative solutions to meet the growing demand for higher performance and more immersive consumer experiences. Designed to give end-users confidence when purchasing HDMI cables for their UltraHD products that may include features such as 4K@60Hz, BT.2020 and HDR Learn more...

HDMI 2.2 Specification Technology Overview

www.hdmi.org

The HDMI Forum, Inc. is comprised of the world’s leading manufacturers of consumer electronics, personal computers, mobile devices, cables, components, silicon; and also includes movie studios, service providers, test labs and test equipment manufacturers. An open trade association, The HDMI Forum’s mission is to foster broader industry participation in the development of future versions of the HDMI specification and to further expand the ecosystem of interoperable, HDMI-enabled products. “Ultra96” is a feature name that manufacturers are encouraged to use to indicate a product supports a maximum of 64Gbps, 80Gbps or 96Gbps bandwidth in compliance with the HDMI 2.2 Specification, and require the Ultra96 HDMI® Cable to ensure a product’s maximum bandwidth is properly supported. eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality. It ensures full compatibility between audio devices and upcoming HDMI 2.2 products.More Info...

Fully-verified Premium HDMI cables are covered by the Premium HDMI Cable Certification Program, which authenticates products to support full 18Gbps bandwidth from the HDMI 2.0b specification with an EMI test to ensure cables minimize interference with wireless signals. Similar to Premium HDMI described above, Ultra HDMI products must be approved and labelled as part of the Ultra High Speed HDMI Cable Certification Program, explained in the diagram below: Smart homes are meant to make life easier, but getting one set up can feel surprisingly complicated. But in the AV world of increasing bandwidth requirements for 4k, 8k and data transmission rates now topping 48Gb, there is a need for higher performing HDMI cables – and, therefore, specified HDMI Standards to ensure different cable types achieve the various specifications.
