Last but not least, HDMI was developed by Sony, Hitachi, Thomson (RCA), Philips, Matsushita (Panasonic), Toshiba and Silicon Image. Those companies really develop a powerful and versatile device for human beings. HDMI brings people so much conveniences and benefits. More and more powerful equipment is bound to emerge in the future and people will enjoy a more comfortable and digital life.
HDMI is superior to all current consumer media formats in that it was designed to be able to carry 8 channels, of 192kHz, 24-bit uncompressed audio. Furthermore, HDMI is capable of transmitting any type of compressed audio format. It is also compatible with all high-definition video formats in existence as well as advanced definition formats and standard definition formats.
It is the first interface which supports uncompressed, all-digital/video in the electronics industry. You just need a single cable and user-friendly connector and then the complicated cabling structure behind the home entertainment would disappear. On the other hand,HDMI offers you an interface which can transmit signals between any audio/video source over a single cable. For example, signals from a set-top box, DVD player, A/V receiver, an audio and/or video monitor and a digital television (DTV) can be easily transferred. Moreover, standard, enhanced and high-definition video, even multi-channel digital audio are all supported by HDMI.
HDMI, short for High-Definition Multimedia Interface, is a widely used standard on audio and video equipment. For example, high-definition television and home theater systems are where HDMI enjoys great popularity. It uses a single cable wrapped with 19 wires, which allows it to carry a bandwidth of 5 gigabits per second (Gbps). Such a bandwidth is twice as high as that needed in the transmission of multi-channel audio and video. It is so powerful that no equipment is able to replace it in the foreseeable future.
