The HDMI Alliance announced the HDMI 2.0 specification at the beginning of September of this year at IFA 2013 in Germany. At the same time, the HDMI 2.0 is also used by authorized manufacturers to demonstrate the application of the HDMI 2.0 interface on the show floor. Earlier in the Taiwan commentary, Steve Venuti, president of HDMI Licensing (LCC), detailed the announcement specifications. Coil Form is special designed for coil bending with L , C,U, G shape according to different application Coil Form Coil Form, Coil Bending Machine, Coil Bender Satis Products Co., Ltd. , http://www.satismachinery.com
The HDMI 2.0 specification is developed for the currently evolving 4K ultra-high image quality image transmission. It mainly provides 18Gbps image transmission bandwidth, 4K@50/60GHz image quality update performance, and stereo audio support for up to 32 channels of output. 1536KHz sound sampling. In addition to the use of some compatible with existing HDMI connection hole, transmission wire, and compatible with 3D image output and CEC (Consumer Electronic), and dynamic automatic mouth synchronization and other functions.
According to Steve Venuti, president of HDMI Licensing Corporation, although HDMI 2.0 is mainly designed for higher quality output performance, it will still comply with the HDMI specification design philosophy and be compatible with older specifications, allowing users to maintain intuitive and lightweight use of existing cables. Specifications and ensure that the output quality has the same or better experience.
According to Steve Venuti, currently HDMI 2.0 mainly focuses on consumer electronics applications. Therefore, based on the competition of the computer-side design of the DisplayPort and the MHL interface designed for mobile devices, it will not actually feel competitive, although The application is very similar, but the basic application model is still different. HDMI is mainly aimed at living home appliances, but DisplayPort and MHL will eventually use HDMI. Therefore, HDMI is considered to be mutually applicable technically.
According to the HDMI 2.0 specification, Steve Venuti revealed that although the new specification incorporates many functional support features, it does not necessarily force the licensee to rigidly add all new specifications. Instead, it allows the licensees to determine the scope of their own authorization. However, before obtaining the HDMI 2.0 specification, licensees still have to obtain the HDMI 1.4 version license.
As for the generation of more meta-applications for the HDMI specification, the HDMI Alliance announced the establishment of the HDMI Forum after the announcement of the HDMI 1.4b specification. The purpose of the HDMI Forum is to attract more market players to join, making HDMI applications no longer limited to TVs, set-top boxes, and recording and playback. Cameras and other equipment, including vehicle carriers, notebook computers, graphics cards, and other product manufacturers, have also joined the forum members to jointly develop specifications, currently accumulating a total of 88 members.
As for related statistics, there are currently 3.5 billion units of HDMI interface equipment used in shipments, and about 1,331 development companies have obtained specifications and authorizations, of which about 34% are Chinese manufacturers, followed by about 19% of the Taiwan area. According to the IFA 2013 in Germany, which has already been announced by manufacturers such as Panasonic and adopting HDMI 2.0 specifications, it is estimated that the fastest 3-6 months will be sold in the market.
Mentioned that the Japanese NHK and other organizations have already begun planning 8K image quality standards, Steve Venuti said that HDMI will not specify the output interface specifications after the introduction of specific content and technology, and will inevitably have relevant interface specifications before the introduction of the new image quality specification. roll out. At the same time, when some members of the HDMI Forum are also the same as the 8K specifiers, the new HDMI specification will not be released after the introduction of the 8K quality specification.
