4x1 HD Digital Audio Switcher from ComputerCableStore™. Easily Switch Between Four
HDTV Devices Using One HDTV Display. Our ex-tend-it 4x1 HD Digital Audio Switcher enables effortless source switching using a single high definition display. A simple and reliable solution, the 4x1 HD Digital Audio Switcher links any four HDTV sources with digital audio (DVD players and satellite set tops) to one HDTV display. It eliminates the need to disconnect then reconnect multiple HDTV sources, saving time by providing a fundamental tool that brings it all together behind the scenes. When all five devices (the display plus the four sources) are connected to the 4x1 HD Digital Audio Switcher and powered on, you simply select which source you want to view on the display using the Switcher, the IR remote that comes with it or any universal remote you program to work with the Switcher.HDCP (high definition content protection) is a standard encoded into the video signal to prevent it from being pirated. If a source device is
HDCP coded and is connected to a HDTV display or projector without the proper HDCP decoding mechanism, the picture is relegated to “snow” or in some cases, very low (480P) resolutions of the images. In order to see HDTV with HDCP compliance, the source, the display and any device in between must be equipped with
DVI connections that can enable HDCP decoding, such as the 4x1 HD Digital Audio Switcher.Simply connect your display to the Switcher's DVI output and your digital audio device to the digital output. Then connect the four sources to the Switcher's
HDMI inputs using the HDMI cables and TOS link cables that come with the Switcher. Once the sources, the Switcher and the display are all powered on and connected, you simply select which source you want to view and listen.
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.
