HDMI is an abbreviation which stands for “HD Multimedia Interface’Â. As the name HDMI suggests, this interface is an interconnectivity standard, which has been created specifically to usher in the new era of multimedia channel audio and high definition video connectivity. Global multimedia giants like Philips, Sony, Panasonic (Matsushita Electric), Hitachi, Silicon Image, Toshiba and Thomson are the primary members of HDMI LLC, which is a non-profit industry that caters to their needs.
HDMI interconnects can carry remote control signals, video and audio on one digital interface.
Here are some of the most obvious advantages of using HDMI 1.3.
Higher data transfer speed
The HDMI 1.3 cable increases the existing Omni-link bandwidth to 10.2 Gbps (340 MHz) which is capable of supporting the demands of all future HD display devices.
Supports Deep Color
The HDMI 3.1 supports a format known as Deep Color. The Deep Color is a new color space that is used in video electronics. The Deep Color format can support 1.8 times as many colors as RGB format. The Deep Color format defines color by an algorithm that is capable of reproducing any color in nature, which is not available with RGB technology.
Incorporates automatic audio lip-syncing capability
The HDMI 1.3 incorporates lip sync capabilities. This means with the aid of HDMI 1.3 interface the system automatically adjusts for the discrepancy in electronic latency between the processing circuits of the image and sound display.
Supports Dolby True-HD and even DTS-HD
The HDMI 3.1 interface, supports the outputs of DTS-HD on the Master Audio Streams and Dolby TrueHD. These two audio outputs are loss-free-audio-codec formats that are used on Blu-ray and also HD DVSs.
Provides special connection
The HDMI 1.3 interface also provides a new small connection so that it can be hooked on with electronic gadgets such as camera recorders (camcorders) for a direct output to HD monitors and TVs.
The Sony PlayStation 3 is the very first product on the electronic consumer market that has used an HDMI 1.3 interface. Epson has also released the powerful digital projector EMP-TW1000 that can support 30-bit Deep Color which is one of the most essential benefits of this digital interface.
Another beautiful thing with HDMI is that it is fully backward compatible with any DVI compliant devices.
The HDMI technology has been so designed that it can use standard copper cable constructions at long lengths. It has been observed during HDMI compliance testing that this new technology allows up to a maximum of ten meters without the use of any repeaters for successfully carrying an HDMI signal to its projection module. However this has also been seen that the receiver chip inside the TV or the projector also plays a major role in defining how long a cable can carry HDMI signal. Those receiver chips that includes a feature known as “cable equalization’ and are capable for compensating weaker signals works better for extending the potential cable length between the two devices that uses HDMI for their signal outputs.
It is always recommended that buyers of HDMI 1.3 cables must necessarily buy their cables from reputed sources as there are many dubious brands that uses the HDMI logo but nevertheless does not perform accordingly.
