4x2
HDMI Switcher from ComputerCableStore.com. Access up to Four Sources From One or Two Displays. Gefen's 4x2 HDMI Switcher routes high definition video in multiple resolutions up to
1080p plus multichannel digital audio from any of four sources. four inputs accommodate the simultaneous connection of up to four high definition video sources, such as satellite systems and HD DVD players. Two outputs send the high definition audio/video signals up to two high definition displays. A digital audio output port is available if you need to direct the audio to an audio receiver. Switching is done via the IR remote that is provided with the unit.HDCP (high bandwidth digital 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 display or projector without the proper decoding mechanism, the picture is relegated to “snow” or in some cases, very low (480P) resolutions of the images. In order to see high resolution digital video with HDCP compliance, both the source, the display and anything in between must be equipped with HDMI connections that can enable HDCP decoding, such as the 4x2 HDMI Switcher.You simply connect all your sources to the Switcher's inputs. Then connect up to two displays on the output ports. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the IR remote.
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.
1080p is the shorthand name for a category of HDTV video modes. The number "1080" represents 1,080 lines of vertical resolution (1080 horizontal scan lines), while the letter p stands for progressive scan (meaning the image is not interlaced). 1080p can be referred to as full HD or full high definition to differentiate it from other HDTV video modes. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total. The frame rate in hertz can be either implied by the context or specified after the letter p (or i), such as 1080p30, meaning 30 Hz.
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.
