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 you
want to extend the beamwidth of your antenna system? If so, then use two similar
receivers/antennas to nearly double the beam width. Or, perhaps pair up a 900Mhz and
2400Mhz video system for the ultimate in frequency diversity and redundancy.
The antenna strategy you choose will depend on your operating environment and application
requirements. Although Oracle cannot eliminate all video problems, using it with a carefully
chosen receiver/antenna setup will certainly help minimize reception issues.

- Page 7 WHEN SERVICE IS NEEDED DURING THE WARRANTY PERIOD: 1. Contact DPC using the “contact us” link instructions found at www.dpcav.com. Please provide the model name, serial number, purchase date, and specific details to the problem. If DPC determines that service is required, they will issue a Return Authorization (RA) number and they will request that you return the unit.
- Page 8 UESTIONS Q: Can I power Oracle from the same 12V battery that operates my two video receivers? A: Yes you can. As a bonus, Oracle’s low battery alarm will tell you when the battery needs attention. Q: To reduce polarization reception problems, I would like to combine a vertical polarized antenna with one that is horizontally polarized.
- Page 9 Q: Can I use Oracle to mix a 900Mhz video receiver with a 2.4Ghz video receiver? A: Yes. Some folks claim that this is the ultimate in diversity methods. Keep in mind that your video camera will probably need to be “buffered” with a video amplifier when it is connected to the input of the two RF transmitters.
