DVI to HDMI : HDMI Basics Part 1

HDMI stands for the High Definition Multimedia Interface, and was initially developed and released in 2002 December. HDMI was mainly developed for carrying an uncompressed video and digital information over the same interconnect, and the first version was named HDMI ver 1.0. After two years of time, HDMI 1.1 was released in the year 2004 May, and was followed by 1.2 in 2005 Aug, and then finally 1.2a in the very year December.



The versions kept getting upgraded, although there weren't many changes done to the previous versions. In November 2006, HDMI 1.3a was released and again 1.3b was released in March, and in June 2009, HDMI was updated to 1.4 version. In 1.4 though, they added an Ethernet channel, and thus HDMI cable requires additional cable.

Even though HDMI came out in the year 2002, it took almost an year for device developers to fully accept the new cable technology and then adopt it int their device. Thus the first HDMI device started to appear in the year 2003. After the launch of first HDMI device, the HDMI has become vary famous, and has even lead to the cross cable supports like dvi to hdmi. Since then there has been a spike growth in the number of devices that have adopted the HDMI technology, and its almost estimated that there are already more than 200 million devices which are HDMI enabled.

Philips, Panasonic, Sony, Slilicone Image, Thmoson and Hitachi were the leading companies which first developed the HDMI standard. Soon the rest of the electronic device manufacturers followed. HDMI is made to be totally compliant with the High Bandwidth Digital Content Protection ( HDCP) which is mainly about providing copyright protection to the digital content. Many of the major movie producers like Disney, Warner Bros, Fox also support HDMI and so do the system operators such as EchoStar.

Benefits of HDMI

When you look at the composite tv cables you'd notice that there are two or more separate cables to connect the audio and video from the source to the destination. But in case of HDMI, the basic idea was to use a a single interconnection which could effectively carry both audio and video signals. And in this case, the data source can be anything like DVD player, A graphics card, set top box.

The first noticeable benefit of HDMI cables or DVI to HDMI cables is the fact that, they readily reduce the mess that is usually caused by the normal composite tv cables. These HDMI cables or dvi to hdmi cables look sleek and are short and are strong. Thus they can be tucked away behind the table.
