1:4
HDTV Digital Audio Splitter from ComputerCableStore™.
Our 1:4 HD Digital Audio Splitter sends high definition video and multichannel digital audio to up to four high definition displays at the same time. It works just like the 1:4 HDTV Splitter, but provides added support for digital audio signals encapsulated with the video in the same connector and cables. The 1:4 HD Digital Audio Splitter very simply and effectively supplements home theaters and digital audio/video systems by allowing an HDTV source, such as a satellite set-top box, HD DVD player, D-VHS player or another HDTV device, to send its audio and video to up to four HDTV displays at the same time.
The 1:4 HD Digital Audio Splitter works with sources and displays equipped with DVI (digital visual interface). To use with HDMI (high definition multimedia interface) sources and displays, Gefen supplies DVI to HDMI Cables and Adapters.
How it works
You simply connect your HDTV source to the 1:4 HD Digital Audio Splitter's HDMI input using the supplied cable. All four displays are connected to the Splitter's four DVI outputs. DVI output 1 is the primary connection and is used for the main display. DVI outputs 2, 3 and 4 follow the main display. The 1:4 HD splitter is HDCP compliant. HDCP (high bandwidth digital content protection) is a standard encoded into the video signal to prevent it from being pirated. To view protected content at its highest resolutions, the source, display(s) and any equipment in between must be HDCP compliant. Otherwise, the picture is very often relegated to "snow" or very low resolutions if at all.

DVI, or Digital Video Interface Technology came about in 1999 as a result of the formation of the Digital Display Working Group (DDWG) a year prior. Their original mission was to create a standard digital video interface for communication between a Personal Computer and a VGA monitor. Recently, however, the consumer electronics industry began implementing DVD players, set-top boxes, televisions, and LCD/plasma monitors with DVI technology.
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers (PCs), video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions. HDMI supports, on a single cable, any TV or PC video format, including standard, enhanced, and high-definition video, up to 8 channels of digital audio, and the Consumer Electronics Control signal. It is independent of the various digital television standards such as ATSC and DVB as these are encapsulations of compressed MPEG video streams (which can be decoded and output as an uncompressed video stream on HDMI). A Digital Visual Interface (DVI) signal is electrically compatible with an HDMI video signal; no signal conversion needs to take place when an adapter is used, and consequently no loss in video quality occurs.
High-definition television (or HDTV) is a digital television broadcasting system with higher resolution than traditional television systems (standard-definition TV, or SDTV). HDTV is digitally broadcast; the earliest implementations used analog broadcasting, but today digital television (DTV) signals are used, requiring less bandwidth due to digital video compression.
High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), or Unified Display Interface (UDI) connections. HDCP does not address whether copying would be permitted by fair use laws. The specification is proprietary, and implementing HDCP requires a license.
