Unlike HDMI Switchers, which are often powered by the HDMI devices connected to them, most HDMI Splitters need an external power source. On September1, 2020, Nvidia launched the GeForce RTX 30 series, the world's first discrete graphics cards with support for the full 48 Gbit/s bandwidth with Display Stream Compression 1.2 of HDMI 2.1. [184] [185] [186] Gaming consoles [ edit ] But before we get too far ahead of ourselves, it's important to note that 10K content isn't available yet. And while we saw 8K televisions at CES this year, 8K content available is really, really hard to come by. So, while HDMI 2.1 provides the opportunity to enjoy super-high-res content, you won't be able to experience it in any meaningful way soon.

The HDMI founders were Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, and Toshiba. [1] Digital Content Protection, LLC provides HDCP (which was developed by Intel) for HDMI. [10] HDMI has the support of motion picture producers Fox, Universal, Warner Bros. and Disney, along with system operators DirecTV, EchoStar ( Dish Network) and CableLabs. [3] 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. First, it’s a switcher with two input ports, so you can connect two media devices (streamer, DVD player, etc’) and switch between them (with a button, or with the supplied remote control). Whereas active HDMI cables require a separate power supply fed from an external source, HDMI Cable Power cables can draw up to 300 mA from the 5V supply of a source directly from the HDMI connector, allowing for less convoluted cable runs in home cinema systems. HDMI Ethernet Channel technology consolidates video, audio, and data streams into a single HDMI cable, and the HEC feature enables IP-based applications over HDMI and provides a bidirectional Ethernet communication at 100Mbit/s. [43] The physical layer of the Ethernet implementation uses a hybrid to simultaneously send and receive attenuated 100BASE-TX-type signals through a single twisted pair. [53] [54] Compatibility with DVI [ edit ] An adapter with HDMI (male, right) and DVI (female, left) connectors An adapter with DVI (male, rear, not visible) and HDMI (female, front) connectorsTotal transmission bit rate is equal to the number of data channels multiplied by the bit rate per channel (binary digits transmitted per second). Each channel transmits one bit (binary digit) per signal, and signals at ten times the character rate. Therefore, the total transmission bit rate (in Mbit/s) = 10 × (character rate in MHz) × (# of data channels). HDCP’s aim is to protect video feeds from illegal copying, and you need to make sure the HDMI splitter you’re buying supports this standard, otherwise most devices you connect to it won’t be able to broadcast anything to your screens.

HDMI 2.1 can go even further, supporting resolutions as high as 10K at 120Hz – though that kind of capability isn't here yet and isn't supported on commercial sets. Large number of additions and clarifications for CEC commands. One addition is CEC command, allowing for volume control of an AV receiver. [5] :§CEC-1.3 a b c Michael Stelts (April 17, 2002).

A new certification program was introduced in October 2015 to certify that cables work at the 18Gbit/s maximum bandwidth of the HDMI 2.0 specification. [79] 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: [80]

What is HDMI and what are the different versions?

HDMI is the most common audio/video connection in use. However, TVs may have as few as one or two HDMI inputs. If you have a lot of HDMI-equipped source devices, such as an upscaling DVD/Blu-ray/Ultra HD Blu-ray player, cable/satellite box, media streamer, and game console that all need to be connected to your TV, there may not be enough HDMI inputs, but don't panic. a b "CEA Announces Publication of New DTV Interface Standard". Business Wire. July 15, 2013 . Retrieved July 17, 2013. For console gaming, however – especially if you’re planning to use something like the PS4 Pro, you might be better off with a 60Hz splitter, which supports 60 frames per second (or even 120Hz for the PS5 – but 4K at 120Hz splitters are harder to find – and they’re considerably more expensive, for now). The Blu-ray Disc Association (BDA) spokespersons have stated (Sept. 2014 at IFA show in Berlin, Germany) that the Blu-ray, Ultra HD players, and 4K discs are expected to be 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 that supports HDCP 2.2.

Devices called HDCP strippers can remove the HDCP information from the video signal so the video can play on non-HDCP-compliant displays, [61] though a fair use and non-disclosure form must usually be signed with a registering agency before use.HDMI Cable Power overcomes the limitation of HDMI 2.1's Fixed Rate Link signalling system, which delivers ultra-fast, high bandwidth signals but can only be preserved for short distances, meaning that passive cables are restricted to just a few metres in length. Arguably one of the more important HDMI 2.1 improvements has nothing to do with video at all. In fact, audio devices, including soundbars and amplifiers, might benefit from HDMI 2.1. The "version" of a connection depends on the versions of the HDMI ports on the source and sink devices, not on the HDMI cable. The different categories of HDMI cable only affect the bandwidth (maximum resolution / refresh rate) of the connection. Other features such as audio, 3D, chroma subsampling, or variable refresh rate depend only on the versions of the ports, and are not affected by what type of HDMI cable is used. The only exception to this is Ethernet-over-HDMI, which requires an "HDMI with Ethernet" cable.

In 2022 an amendment to the specification for HDMI 2.1a was announced which introduced a new feature called HDMI Cable Power, which enables users to use HDMI cables that are much longer than are currently supported, without the need for a separate power connector. To take advantage of the feature, however, users will need to have both a new type of HDMI cable and an HDMI source device that supports the feature. We're yet to see any products announced that include it, but it's worth noting that new HDMI cables with Cable Power will ship with a separate power connector, normally a USB Micro-B or Type-C, for use with non-compatible source devices.

HDMI vs HDMI 2.0: How is HDMI 2.0 better for HDR?

HDMI 2.1 supports up to 48 Gbps bandwidth. That's double what you can get now from HDMI 2.0. So, while you might be able to pump 8K content at 30 frames per second through an HDMI 2.0 cable, you'll be pushing the technology to its limits. On HDMI 2.1, it'll be able to handle that with ease. In fact, you'll be able to drive 10K content at 120 frames per second through ah HDMI 2.1 cable and not worry about it. This is also important when you have a subscription to a streaming service that limits the number of simultaneous streams you can watch. For example, if you have the Standard Netflix membership, you can only watch up to two streams at once. High-Definition Multimedia Interface ( HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. [3] HDMI is a digital replacement for analog video standards. 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. [224] 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). Display Stream Compression (DSC) is used to allow up to 8K Ultra HD (7680 × 4320) 120Hz HDR video, and to support Ultra HD 60Hz video over a single lane. [224] See also [ edit ]
