HDMI Specification Versions - Overview
HDMI was first introduced in 2002 by the seven founders of the HDMI specification: Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, and Toshiba. Since that time, HDMI standards have continued to evolve and improve. Through April of 2015, there have been six different versions of HDMI standards released, each one adding features to the previous version. It is important to note that the newest versions of HDMI specifications do not necessarily require a new cable. For example, all HDMI 2.0 features are backward compatible with existing high speed (category 2) HDMI cables that were used with HDMI version 1.4. Stated more simply, if you have an existing HDMI cable, it may work with your new device. If it does not seem to pass through all of the features, then you may need to purchase a newer design cable.
HDMI 1.0 was introduced in December of 2002 as a single-cable digital audio video connection. This standard certified supporting a maximum throughput of 4.9 Gbps, video resolutions of up to 1080p at 60Hz, and eight channels of 24-bit audio using Pulse Code Modulation (PCM). This original specification remains useful today for standard cable TV set top boxes and many home audio devices.
HDMI 1.1 released in May of 2004 added support for high resolution uncompressed DVD audio.
HDMI 1.2 made its debut in August of 2005 supporting additional formats and modified specifications for low-voltage devices including PC video cards. A modification, HDMI 1.2a in December 2005 clarified additional specifications.
HDMI 1.3 became available in June of 2006, supporting increased bandwidth throughput, increased color support technology, and developing High Definition technologies. This version also supported a new type of mini connector for use with camcorders. Some of these new features were beneficial to improved gaming devices as well. Between November of 2006 and August of 2008 modifications known as HDMI 1.3a, 1.3b, 1.3b1, and 1.3c clarified specification and testing parameters further.
HDMI 1.4 was released in May of 2009 with several new features beneficial to consumer end-users including 3D support, Ethernet over HDMI, Audio return channel, and additional color support along with enhanced 2K and 4K resolutions. These features allowed for less separate cables between compatible devices. A new micro HDMI connector was also approved, as was a new specification of cable for use in automotive applications. In March of 2010, HDMI 1.4a added support for 3D broadcast content and in October of 2011 HDMI 1.4b increased the resolution and refresh rate support for 3D video over HDMI.
HDMI 2.0 was released with significant updates in September 2013. Bandwidth throughput support was increased to 18 Gbps, improved resolution support of 4K@50/60 (2160p), support for up to 32 audio channels and up to 1536 kHz audio. Support was also added for multi-stream video and wide angle theatrical 21:9 aspect ratios. Improved 3D sampling was added, as well as updated CEC extension support for multiple devices through a single cable. In April of 2015, HDMI 2.0a added additional support for HDR content.
