HDMI is a compact audio/video interface using latest interconnection technology for transmitting uncompressed digital data. Because the signal remains digital there is no loss from conversion, delivering results superior to older analogue technologies.
HDMI connects digital audio/video sources from set-top boxes, DVD players, HD DVD players, Blu-ray Disc players, AVCHD camcorders, personal computers (PCs), video game consoles such as the PlayStation 3 and Xbox 360, and AV receivers) to compatible digital audio devices, computer monitors, video projectors, and HD LCD / Plasma screens.
The new HDMI Version 1.4 provides the most advanced AV data transmission available. With 4K & 2K resolution support, HDMI v2.4 enables video resolutions far beyond 1080p, increases the maximum resolution to 4K x 2K (3840x2160p at 24 Hz/25 Hz/30 Hz and 4096 x 2160p at 24 Hz, the resolution used in digital theatres.
HDMI v1.4's Ethernet Channel (HEC) allows for a 100 Mb/s Ethernet connection between the two HDMI connected devices; Users can take full advantage of their IP-enabled devices without a separate Ethernet cable. Meanwhile the Audio Return Channel (ARC) allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to surround audio system, eliminating the need for a separate audio cable.
Experience lifelike 3D entertainment in your home; HDMI v1.4 defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theatre applications.
