What are the distinctions in between HDMI versions 1.1, 1.2, 1.3 a, 1.4 a and 2.0?
- Support for DVD Audio.
- Includes features and capabilities that increase HDMI's appeal for use in both the CE and PC markets. Particularly, the features and adjustments for HDMI 1.2 consist of: Support for One Bit Audio format, such as Super Audio CD's
DSD (Direct Stream Digital), modifications to use much better support for present and future PCs with HDMI outputs, consisting of: availability of the widely-used HDMI Type A connector for PC sources and display screens with full support for PC video formats, capability for PC sources to use their native RGB color space while maintaining the option to support the YCbCr CE color area, requirement for HDMI 1.2 and later on displays to support future low-voltage (i.e., AC-coupled) sources, such as those based upon PCI Express I/O innovation. HDMI 1.2 a -Customer Electronic Control (CEC) features and command sets and CEC compliance tests are now totally specified.
- Production of variation 1.2 a of the HDMI Compliance Test Spec (CTS), that includes a CEC Supplement. HDMI CTS 1.2 a has been upgraded for technical consistency with HDMI Spec 1.2 an as well as to the recently released HDMI Spec 1.2. Substantially, CTS 1.2 an includes extra cable television and port testing and Licensed Testing Center (ATC) submission requirements. Particularly, under CTS 1.2 a, the Adopter shall submit for testing to the ATC any new HDMI cable television whose length exceeds formerly tested cables. In addition, HDMI Licensing, LLC will preserve a list of approved ports. For a gadget to pass CTS 1.2 a screening at an ATC, all ports on such device must appear on the authorized port list. To include a connector to this list, the vendor must submit to the ATC or HDMI Licensing, LLC full and passing screening outcomes.
HDMI 1.3/ 1.3 a:
- Greater speed: HDMI 1.3 increases its single-link bandwidth to 340 MHz (10.2 Gbps) to support the needs of future HD display devices, such as higher resolutions, Deep Color and high frame rates. In addition, developed into the HDMI 1.3 specification is the technical structures that will let future variations of HDMI reach substantially greater speeds.
- Deep Color: HDMI 1.3 supports 10-bit, 12-bit and 16-bit (RGB or YCbCr) color depths, up from the 8-bit depths in previous versions of the HDMI spec, for stunning rendering of over one billion colors in unprecedented detail.
- More comprehensive color area: HDMI 1.3 adds assistance for "x.v.Color ™" (which is the consumer name explaining the IEC 61966-2-4 xvYCC color standard), which eliminates current color area constraints and enables the display of any color viewable by the human eye.
- New mini connector: With little portable devices such as HD camcorders and still cams demanding seamless connectivity to HDTVs, HDMI 1.3 offers a brand-new, smaller sized form aspect connector alternative.
- Lip Sync: Because consumer electronics gadgets are using significantly complicated digital signal processing to improve the clearness and information of the content, synchronization of video and audio in user devices has become a higher challenge and might potentially require intricate end-user adjustments. HDMI 1.3 incorporates automated audio synching capabilities that allow gadgets to perform this synchronization instantly with total accuracy.
- New HD lossless audio formats: In addition to HDMI's present ability to support high-bandwidth uncompressed digital audio and all currently-available compressed formats (such as Dolby ® Digital and DTS ®), HDMI 1.3 includes extra support for brand-new lossless compressed digital audio formats Dolby TrueHD and DTS-HD Master Audio ™.
HDMI 1.4/ 1.4 a:
- HDMI Ethernet Channel: The HDMI 1.4 requirements adds a data channel to the HDMI connection, enabling high-speed, bi-directional communication. Linked devices that include this feature can send and get data through 100 Mb/sec Ethernet, making them immediately ready for any IP-based application. The HDMI Ethernet Channel permits internet-enabled HDMI devices to share an internet connection by means of the HDMI link, with no need for a separate Ethernet cable. It also provides the connection platform that will allow HDMI-enabled parts to share material in between gadgets * Not presently implented on Denon gadgets.
- Audio Return Channel: The most recent specification includes an audio channel that will minimize the number of cable televisions required to deliver audio "upstream" from a TELEVISION to an A/V receiver for processing and playback. In cases where a TELEVISION features an internal content source, such as an integrated tuner or DVD player, the Audio Return Channel allows the TELEVISION to send audio data upstream to the A/V receiver by means of the HDMI cable television, eliminating the need for an additional cable television.
-3D: The 1.4 version of the requirements defines common 3D formats and resolutions for HDMI-enabled devices, making it possible for 3D video gaming and other 3D video applications. The requirements standardizes the input/output portion of the house 3D system, helping with 3D resolutions up to dual-stream 1080p.
-4K Resolution Support: The new spec enables HDMI devices to support very high HD resolutions, efficiently four times the resolution of a 1080p device. Assistance for 4K permits the HDMI user interface to send digital material at the same resolution as the state-of-the-art Digital Cinema systems used in lots of movie theaters.
- Expanded Assistance For Color Spaces HDMI now supports color areas developed specifically for digital still electronic cameras, enabling more accurate color rendering when seeing digital images. By supporting sYCC601, Adobe ® RGB, and Adobe ® YCC601, HDMI screen devices can showing more accurate, life-like colors when linked to a digital video camera.
- HDMI Micro Connector: (Type D) The HDMI Micro Connector is a considerably smaller 19-pin HDMI adapter supporting as much as 1080p resolutions for portable gadgets such as cellular phone, portable media players, and digital electronic cameras. This brand-new port is approximately 50% smaller sized than the size of the existing HDMI Mini port.
- Automotive Connection System: (Type E) The Automotive Connection System is a cabling specification created to be used for in-vehicle HD content circulation. The HDMI 1.4 specification offers a service created to meet the rigors and ecological concerns commonly discovered in cars, such as heat, vibration and sound. Using the Automotive Connection System, cars and truck manufacturers now have a viable option for HD circulation within a lorry.
HDMI 2.0, described by some makers as HDMI UHD, was launched on September 4, 2013.
HDMI 2.0 increases the optimum TMDS per channel throughput from 3.4 Gbit/s to 6 Gbit/s which enables an optimum overall TMDS throughput of 18 Gbit/s. That allows HDMI 2.0 to carry 4K resolution at 60 frames per second (fps).
Other features of HDMI 2.0 consist of the alternatives of the Rec. 2020 color space, Dual View, 4:2:0 chroma subsampling, 25 fps 3D formats, as much as 32 channels of audio, up to 1536 kHz audio (for example 7.1 channels of 192 kHz), approximately 4 audio streams, 21:9 element ratio, the HE-AAC and DRA audio standards, vibrant automobile lip-sync, enhanced 3D ability, and extra CEC functions.
HDMI 2.0 a was launched on April 8, 2015 and added assistance for high dynamic range (HDR) video.
Further progressions will definately happen and we will do our best to stay on top of it all for you. Hope you enjoyed this post. Research information came primarily from the Denon and HDMI Org website.
