What is hdmi?
Developed jointly by Sony, Hitachi, Thomson (RCA), Philips, Matsushita (Panasonic), Toshiba and Silicon Image, the High-Definition Multimedia Interface (HDMI) is a digital interface which combines digital video, multi-channel audio and inter-component command data in a single digital interface. HDMI is a fully digital transport that is designed specifically for the consumer electronics market and supports all digital video formats.
HDMI is an industry standard digital interface that supports both audio and video data components. HDMI has quickly become the standard for connecting consumer electronic devices together and was pioneered by a group of companies including Sony, Philips, Hitachi and Matsushita. HDMI supports standard, enhanced, or high-definition video as well as multi-channel digital audio on a single industry standard cable. HDMI is capable of carrying any type of compressed audio data such as Dolby or DTS. HDMI can transmit all HDTV standards and supports 8 channel digital audio and up to 5Gbps (Giga bits per second ) bandwidth.
1. The short answer… Put simply, HDMI is a new connection type that carries both digital audio and digital video (at resolutions up to 1080p) in a single cable. It can be found on HDTV’s, some high-definition cable and satellite boxes, upscaling DVD players, the new HD disc formats HD-DVD and Blu-ray, and it is slowly making its way to surround sound receivers and processors. If you are buying a new HDTV, you should make sure the set includes an HDMI input. If your existing HDTV has a DVI input, you can use an adapter or a cable with HDMI on one end and DVI on the other to feed HDMI video data to the TV (you’ll need to make sure your set’d DVI input has HDCP copy protection protocols included, though). HDMI’s video format is borrowed straight from DVI, which was developed originally by the computer industry for use with LCD monitors and then brought over to the consumer electronics world for use with HDTV’s. When DVI was adopted by HDTV manufacturers, it was paired up with a new secu
HDMI (High-Definition Multimedia Interface) is the newest interface for audiovisual equipment such as high-definition television and home theater systems. With 19 wires wrapped in a single cable that resembles a USB wire, HDMI is able to carry a bandwidth of 5 Gbps (gigabits per second). This is more than twice the bandwidth needed to transmit multi-channel audio and video, future-proofing HDMI for some time to come. This and several other factors make HDMI much more desirable than its predecessors, component video, S-Video and composite video. HDMI is an uncompressed, all-digital signal, while the aforementioned interfaces are all analog. With an analog interface, a clean digital source is translated into less precise analog, sent to the television, then converted back to a digital signal to display on screen. At each translation, the digital signal loses integrity, resulting in some distortion of picture quality. HDMI preserves the source signal, eliminating analog conversion to deli
