HDMI or high definition multimedia interface is the innovative new technology in the AV (audio/video) industry. The technology makes it possible to combine the audio and visual signals and offers exceptional advances in digital entertainment.
The HDMI technology was jointly developed by Sony, Philips, Panasonic, Toshiba, Hitachi, Thomson and Silicon Image. It has also been a driving force behind high-definition TVs, HD-DVD, Blu-ray players and all other types of AV products.
Defining HDMI cables
An HDMI cable is a simple plug-in device that transmits high definition video resolution and multiple audio channels using a single cable. These cables work by transmitting digital signals from the AV source, be it a DVD player, an A/V receiver or a satellite receiver to another digital device.
As all HDMI cables have 24 bit 8 channels, they are able to carry transmission of uncompressed audio. However, they also support compressed audio formats like DTS and Dolby.
Features of HDMI cables
HDMI cables have the capacity to carry high quality video – 720p, 1080I and 1080p. Multi channel surround sound and stereo output is also a part of the HDMI package. Moreover, HDMI technology also supports formats like NTSC, PAL and 480p.
As HDMI technology carries digital data, it is highly superior to analogue devices. Unlike analogue cables, there is no compression of data. This eliminates the loss of audio or visual details.
