The HDMI cables have revolutionized the way video and audio devices are connected and it is with good reason that this mode has become the leading form of connecting cables. It gives the user a lot of control of the devices and allows easy operation. It also allows for superior picture and sound quality. This is enabled by its high definition digital transmission. However, one of the understated benefits of HDMI is its allowance for future technological advancement. With its double amount of bandwidth needed to transmit both audio and video data, the HDMI is certainly set for any future changes.
There are five basic versions of the HDMI, which have been released to date. However, the most common four types of cables are the 1.0, 1.1, 1.2 and 1.3. The 1.4 version is the latest release in the market and the most improved. A look at each of these versions is important, especially when you want to buy, as you will be able to get a cable suiting your needs. The first version, 1.0, was standardized in late 2002 and supports HD 1080p as all other models and is compatible with most DVD audio versions, including Dolby Digital and DTS.
The second version comes with audio DVD support which allows the streaming of 5.1 channel audio by users of compatible players without the need for extra RCA cables. The third version has two categories, the 1.2 and 1.2a. This comes with Super Audio CD support which eliminates the need to rely on analogue cables to listen to SACD. It also comes with a type A PC connector. The fourth version is also in categories; the 1.3, 1.3a, 1.3b and 1.3c. Its major improvement is the support of Dolby TrueHD and DTS. It also allows for HD maestro audio, which is used in Blu-ray players. The version also comes with an increased bandwidth by a factor of 2 for every 10Gbps.
The latest version is the 1.4 and this was ratified in 2009. It has significant improvements, with the major one being the inclusion of a HDMI Ethernet connection, which allows for a two-way connection between compatible components and can transfer 100Mb. It also supports 3D in full 1080p and normal resolutions up to 3840p/2160p. It also has a return audio channel allowing for data to be sent to and from television allowing viewers to hear from the television with just a single cable. It also supports photographic colour standards like sYCC601, Adobe YCC601 and Adobe RGB allowing easier compatibility with digital still cameras. This is certainly the way to go for tech geeks!
