ORACLE VIDEO DIVERSITY CONTROLLER
ORACLE V1.4 ©2007 DIGITAL PRODUCTS COMPANY PAGE 1 July-2007 ORACLE VIDEO DIVERSITY CONTROLLER The Oracle video diversity controller is used to bridge two wireless video receivers together. Dual receivers can be used to help reduce RF multi-path problems, as well as allow for other signal improving techniques. FEATURE SUMMARY # Universal wireless video receiver compatibility (NTSC or PAL). # Two channel audio support (stereo audio or voice/data). # Very high bandwidth. No A/V signal degradation. # Two buffered video outputs. # Buffered audio output. # No special installation requirements (uses standard RCA connectors). # Low voltage alarm. # Operates on 6VDC to 14VDC (90mA typical). WHAT IS IT? Oracle is an intelligent video switch with two A/V (audio/video) inputs that are merged into a single output. In a typical installation, it constantly monitors the video signals from two user supplied wireless video receivers. Whenever Oracle determines that the currently chosen A/V source has corrupted video, it automatically switches over to the other A/V source (if it is error free). The switching is very fast, which helps maintain A/V quality. Oracle can be used to create a spatial diversity antenna system. This configuration involves placing the antennas (from two receivers) at slightly different locations. As little as a few inches apart is enough to offer some signal improvement. Spatial diversity is used to reduce multipathing interference, which is a common nuisance with RF wireless video systems. It is also possible to install vastly different antennas on the two video receivers to enhance the overall antenna performance. For example, you can combine a moderate gain patch antenna and a high gain directional Yagi for automatic switching from short to long range. Maybe…
