Video System Tips > Combining Audio / Video Sources
How do we combine several different types of video sources into our projector and monitors?
Sometimes we need to combine several different types of video input sources into one output source. For example, we might have Composite video from a VCR, Component Video from a DVD player, XGA from one computer and DVI from a second computer. We might also have S-Video from Satellite receiver. All of these sources need to feed into a video projector and possibly video monitors.
The way to accomplish this is by using a Switcher / Scaler such as the VP-719XL. It will switch both the video and audio at the same time.
.The Kramer VP-719XL is a true multi-standard video to RGBHV scaler that converts composite video, s-Video, component video (SDTV and HDTV), VGA-through-UXGA, and DVI-D signals to fourteen user-selectable pixel rates: VGA (640x480), SVGA (800x600), XGA (1024x768), SXGA (1280x1024), UXGA (1600X1200), 1024x852, 1024x1024, 1366x768, 1365x1024, 1280x720, 720x483, 852x480, 1400 x 1050, as well as a user desirable output mode. The machine also acts as a 7-input Seamless Presentation switcher.
The VP-719XL digitally reprocesses the signal to correct mastering errors, and regenerates the video at a chosen line and pixel rate format, providing native-resolution video for LCD, DLP and Plasma displays. The model allows scaling of any graphics resolution to any other resolution (scaling for example, a VGA input to an UXGA output, or an SXGA input to an SVGA output). It incorporates a unique graphics-scaling engine with image enhancement algorithms, which are built into the firmware.
The Kramer VP-719XL is specifically designed to improve video quality by reducing Chroma noise. Audio channels are switched in audio-follow-video mode. The unit can be controlled via front panel touch keys, Infra Red remote control, and RS-232. It features a user-friendly on-screen display for making the adjustments. The VP-719XL incorporates a full scale ProcAmp for video and audio correction and enhancement, and offers 3:2/2:2 pull down. The VP-719XL includes a front panel lock and supports firmware upgrade via RS-232. It is housed in a 19” 1U, rack-mountable metal enclosure and uses a universal 100-240VAC automatic power supply.
