A user can switch between different video sources and view them on a single display device using a Video Switch. This device is hassle free because you don't have to keep disconnecting and reconnecting different video sources. The clarity of images is such that it appears as each source is connected directly to the display. Supporting resolutions of up to 1900 x 1200, this piece of hardware is designed for applications where multiple high resolution computer video signals must be switched to one display. These Video switches are available in various formats ranging from two inputs connected to one output up to sixteen input sources connected to a single output. These units can also be cascaded to form a greater matrix of inputs to a single output.
Out of the various models of these switchers, the most recent is the DVI Switch which enables multiple computers with the, DVI interface, to one DVI display device. These switches come with 2 or 4 ports and are available with or without audio eliminating the need for separate setups for video and audio. A matrix version is also available for multiple DVI inputs and outputs. Equipped with built in amplifier circuits there is no ghosting of images. These DVI switch units support display resolutions including SXGA 1280 x 1024 and 480p, 720p, 1080p for HDTV's or 1600x1200 at a pixel frequency of 250MHz. These units are CE, FCC and RoHS compliant, and are compatible with PC based windows and MAC systems.
All variants of the Video Switcher such as the manual, automatic and matrix switchers use front panel buttons, hot keys, RS232 or infra red remote for switching between input sources. They support DDC, DDC2 and DDC2B protocols. You can also use the auto scan mode for monitoring PC's. Front panel LEDs indicate the status of connected devices. Hot pluggable, these devices do not require a user to power off a system when additional input sources are connected or disconnected. 15-pin HD connectors are used for all computer-video input and output connections. These switches are available either as a standalone device or as rack mounted devices.
The Video Switch is used in educational, commercial, security and Surveillance, multimedia and digital signage applications due to their ability to present information from various sources to a single output device.
