Abstract

A video security system (10) capable of monitoring and recording fixed and moving targets and recording management information into a video signal such that the text can be removed from the video image produced by the video signal at playback of the recorded video signal. The VSS (10) allows a camera (70b) to switch (toggle) between two or more view positions of interest and to set the view positions into memory by pressing a single switch. The cameras (70b) are controlled to move rapidly, but accurately, between the positions within controlled parameters of speed and acceleration—including a period of substantially zero acceleration between changes in the rate of acceleration.

Claims

1. A non-invasive text insertion system comprising:

a. a video signal receiver connected to a processor;

b. a video signal source connected to the processor;

c. the processor inserting textual information on a horizontal portion of the video signal to create a text video signal which does not obliterate video information, the processor sending the video signal to the receiver upon receipt of a trigger signal and transmitting the text video signal to the receiver in the absence of the trigger signal; and

d. a controller generating the textual information and the trigger signal.

2. The text insertion system of claim 1 wherein the textual information is data.

3. The text insertion system of claim 1 wherein the processor sends the text video signal to a video recorder.

4. The text insertion system of claim 1 wherein the receiver is a video display unit.

5. The text insertion system of claim 1 wherein the controller controls the presence or absence of the video signal.

6. The text insertion system of claim 1 wherein the processor is connected to a video display unit and a video recorder and wherein the text video signal is recorded.

7. The text insertion system of claim 6 wherein an output of the video recorder is used as the video signal source.

8. The text insertion system of claim 1 wherein the horizontal portion is the horizontal line interval of the video signal.

9. A non-invasive video encoder for data comprising:

a. a processor having a record mode and a display mode;

b. a data source connected to a processor;

c. a video signal source connected to the processor;

d. a video display connected to the processor;

e. a video recorder connected to the processor;

f. the processor in record mode encoding the data on a horizontal portion of the video signal and routing the video signal to the video recorder;

g. the processor in display mode stripping the data from the video signal, leaving the complete video signal intact before routing the video signal to the video display upon receipt of a trigger signal, and decoding the data from the video signal and sending the video signal and the decoded data to the video display in the absence of the trigger signal.

10. The encoder of claim 9 wherein the data is textual.

11. The encoder of claim 9 wherein the video output of the video recorder is used as the video signal source.

12. The encoder of claim 9 wherein the processor encodes data on the horizontal line interval of the video signal.
