The progress of HDMI and High Definition has been rapid. There have been over 8 versions of HDMI cable since it's introduction back in 2002. In this article we explore the time line of HDMI.
All HDMI cables (High Definition Multimedia Interface) allow the transmission of digital signals between devices such as HD TVs and computers, games consoles, cameras and other video/audio equip products.
The very first HDMI cables became available in 2002 and in the eight years since the technology has improved at a rapid pace. HDMI cables were originally developed by technology and electronics firms to improve on DVI (Digital Visual Interface) products by using a smaller connector, adding support for digital audio and allowing connection with other consumer products as DVI did not support audio .
Authorized Testing Centres (ATCs) were established to ensure high standards across all HDMI cable manufacturers and since the launch of the technology millions have been sold worldwide.
The Many Versions of HDMI cables
The first versions of HDMI cables have been continuously developed upon to the point the very latest products offer wireless support, high quality video and audio and can transmit data at incredible speeds without loss of information.
Version 1 - 1.2
HDMI cables version 1, released in December 2002, offered a single-cable for digital audio/video connector and was quickly followed by 1.1 five months later which added support for DVD-Audio. Just three months after that version 1.2 was developed, this gave increased audio support and PC connectivity. Version 1.2a came on to the market a year after the very first HDMI cables and demonstrated further the pace of development in the High Definition market.
In June 2006 Version 1.3 was released with increased single-link bandwidth and boosted colour support.
Audio was also enhanced with output for DolbyTrueHD and DTS-HD Master Audio and audio syncing capability. A Type C Mini connector was also added for use with portable devices such as digital cameras. Version 1.3a came in November 2006, with 1.3b, 1.3b 1 and 1.3c following over the next year, representing the differences in testing and compliance that were introduced.
Version 1.4 (High speed HDMI with Ethernet)
HDMI 1.4 was launched in May 2009 with increased resolution, bringing HDMI cables into the home cinema arena. This version also enabled Ethernet connection and a micro HDMI connector. Version 1.4 also supported 3D technology with 1.4a, the very latest HDMI cable released in March 2010, adding further 3D formats.
HDMI cables are set to develop even further in the coming months and years, having already become a hugely important technology in homes around the world. As increased demands are placed on consumer electronics the products will have to keep up and offer further advantages and improvements to stay in the market. HDMI cables are already future-proof with the ability to transmit 10.2Gbps and have proved their worth and popularity.
