Some TV manufacturers only support Dolby Digital, while others only support two-channel stereo. Support for all relevant audio codecs isn’t compulsory, so you can’t simply assume that a TV will be able to send a 5.1 Dolby Digital The biggest problem for HDMI ARC is manufacturers have been left to pick and choose which elements of the protocol they want to include. This means some ARC-enabled products will work together, while others will not. HDMI v1.3, launched in 2006, added automatic audio syncing, although it was only optional for manufacturers. * Availability of a new mini connector for devices such as camcorders. If the disc player can decode these streams into uncompressed audio, then HDMI 1.3 is not necessary, as all versions of HDMI can transport uncompressed audio. TrueHD and DTS-HD are lossless audio codec formats used on HD DVDs and Blu-ray Discs. * Supports output of Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers. * Incorporates automatic audio syncing (lip sync) capability. * Optionally supports 30-bit, 36-bit, and 48-bit xvYCC with Deep Color or over one billion colors, up from 24-bit sRGB or YCbCr in previous versions. * Increases single-link bandwidth to 340 MHz (10.2 Gbps) * Requirement for HDMI 1.2 and later displays to support low-voltage sources. * Ability for PC sources to use native RGB color-space while retaining the option to support the YCbCr CE color space. * Availability of HDMI Type A connector for PC sources. * Added support for One Bit Audio, used on Super Audio CDs, up to 8 channels. Supports up to 165Mpixels/s video (1080p60 Hz or UXGA) and 8-channel/192 kHz/24-bit audio. Single-cable digital audio/video connection with a maximum bitrate of 4.9 Gbit/s. Type A is electrically compatible with single-link DVI-D. The plug outside dimensions are 13.9 mm wide by 4.45 mm high. The standard Type A HDMI connector has 19 pins, with bandwidth to support all SDTV, EDTV and HDTV modes and more. With version 1.3, HDMI now also supports lossless compressed streams such as Dolby TrueHD and DTS-HD Master Audio. HDMI supports up to 8 channels of one-bit audio, such as that used on Super Audio CDs at rates up to 4x that used by SuperAudio CD. HDMI also includes support for 8-channel uncompressed digital audio at 192 kHz sample rate with 24 bits/sample as well as any compressed stream such as Dolby Digital, or DTS. For example, previously, the maximum pixel clock rate of the interface was 165 MHz, sufficient for supporting 1080p at 60 Hz or WUXGA (1920x1200), but HDMI 1.3 increased that to 340 MHz, providing support for WQXGA (2560x1600) and beyond. Each concurrent version of the specification uses the same cables, but increases the throughput and/or capabilities of what can be transmitted over the cable. It is a modern replacement for older analog standards such as RF - coaxial cable, composite video, S-Video, SCART, component video and VGA, and the consumer electronics replacement for older digital standards such as DVI.ĭevices are manufactured to adhere to various versions of the specification, where each version is given a number, such as 1.0 or 1.3. In 2006, HDMI began to appear as a feature on HD camcorders and high-end digital still cameras. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game console, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV and HDTV). The connector is relatively small, similar in size to a USB Type A connector, and has 19 pins. HDMI can handle 480i, 480p, 576i, 576p, 720p, 1080i, 1080p, 1440p, 4K, 8K, 10k and will handle even higher video resolutions in the future. HDMI allows a high bandwidth video and audio connection all in one cable. Most HDTV sets sold after 2005 have HDMI inputs. More and more devices are showing up with HDMI ports. The HDMI digital audio/video hookup has been available since late 2002. New versions / revisions / releases of HDMI If you do not see any labels on the HDMI ports then you will have to look at the TV specifications If you see HDMI eARC as opposed to only HDMI ARC, then you know you have HDMI 2.1 because eARC only becameĪvailable with HDMI 2.1. Look on the back of the TV and see if the HDMI ports are labeled or If you see you haveĪ HDMI 2.0 chipset but if you see it is HDMI 2.1 because HDMI 2.0 has a maximum refresh rate of 60Hz. How can I tell if my 4K TV is HDMI 2.0 or HDMI 2.1? Technology advances, new chipsets are used in devices with the latest specifications and newer HDMI deviceīe required for the increased data transfer speeds. Specifications but it is not mandatory for a manufacturer to comply with every aspect of the specification. Manufacturers can choose to adopt features of HDMI HDMI is a set of specifications for electronic components.
