The operator can select from up to sixteen source videos. Universal inputs accept composite video, s-video, component video, and computer video sources (640x480 VGA to 1600x1200 UXGA). Sources are scaled to match the native resolution or "sweet spot" of the projection devices to ensure optimal image quality. Thirteen different transition effects including dissolves, wipes, cuts, and fade are supported. The duration of each transition effect is programmable. Each screen output supports two buffered program outputs (one five-wire BNC and one HD-15) and a preview output (HD-15). Auxiliary outputs are provided on the rear panel of the unit for feeds that do not require transition effects or scaling.
The ScreenPro PLUS user interface simplifies system setup, adjustment, and control. To perform a transition, the operator simply selects a preview source(s) and presses a key to simultaneously transition up to six screens using any of the thirteen transition effects. Sixty-four preset memories allow complex control sequences to be "learned" for quick recall. Presets can include information about sources, effects, transition rates, PIP's, keying, and auxiliaries. Since all presets are recalled to the preview Monitors, the operator can view, edit, and recall presets without affecting the program outputs.
System Modularity
ScreenPro Plus has been designed to work seamlessly with Folsom's ScreenPro product offerings. This allows customers to utilize Folsom's ScreenPro products for single-screen applications and to utilize the same units in multi-screen applications when combined with ScreenPro Plus. For example, ScreenPro Plus Model 1604 with four-screen output can be utilized with two standard ScreenPro units to support a sixscreen show. The ability to mix and match units to support different types of shows provides both premium performance
Used Video Switcher
Video switchers, also known as a video display controller (abbreviated to VDC) is essentially the key component of a video signal generator. This kind of vision mixer is used for generating a visual signal in computers, and in some cases an audio signal too, although this is just a secondary function. The video switcher first made its appearance in our homes in the first types of home computers, such as the old Commodores and Spectrums, and is now an integral part of video signal generator logic.
A video mixer cannot work alone however, as it needs support from various other parts of the computer to work. For example, pixel data is stored in the computerâ??s RAM, while character fonts are held in the ROM. Therefore, the video switcher chip will usually be totally integrated into the main computer, and so users will be able to see the video RAM it gives in the CPUs memory map. It can also act as a co-processor that acts independently, although this is not usually the case.
The video switcher is generally available in three different formats. Video shifters are the most basic type of production shifter, and take care of the video timing signals. These obtain data one byte at a time from the CPU, and use synchronization signals to produce a video signal. The CTRC video switcher reads data directly from the computerâ??s RAM, and this is then outputted either through a ROM or directly. Far more complex are video interface controllers. This kind of video switcher supports sprites and video RAM which is dedicated towards color attributes, thus making extremely high-resolution images possible.
