Digital security surveillance system
First Claim
1. A method, comprising:
- receiving a plurality of video signals from video surveillance feeds in a video surveillance system;
storing each video signal of the plurality of video signals as a digital video signal on at least one storage device in communication with the video surveillance system;
in response to receiving a command to view a specific video surveillance feed, extracting a digital video signal for the specific video surveillance feed from the at least one storage device;
simultaneously causing display of the extracted digital video signal and a real time video signal of the plurality of video signals, content of the extracted digital video signal is different from content of the real time video signal; and
wherein the display step further comprises;
switching between stored digital video signals and real time video signals of the plurality of video signals in response to a command from the user to view specific video surveillance feeds.

Abstract
A digital security surveillance system allows a user to store selected security surveillance feeds while the user is simultaneously watching or reviewing another feed. User control commands are accepted and sent through the system. The system parses the resulting digital stream and generates identifying information associated with at least one video segment of the digital stream. The video segments are stored on a storage device. When a security surveillance feed is requested for display, a corresponding stored digital stream is found and its video segments are extracted from the storage device and sent to a decoder that converts the digital stream into display output signals. The security surveillance feeds can be simultaneously sent to an external storage device such as a DVD recorder or VCR.

13. A video surveillance system, comprising:
-
a plurality of input devices that receive video signals from video surveillance feeds in the video surveillance system; at least one storage device in communication with the video surveillance system; a video signal storage device, implemented at least partially in hardware, that stores each video signal of the plurality of video signals on the at least one storage device as a digital video signal; a first subsystem, implemented at least partially in hardware, that, in response to receiving a command to view a specific video surveillance feed, extracts a digital video signal for the specific video surveillance feed from the at least one storage device; a second subsystem, implemented at least partially in hardware, that simultaneously sends the extracted digital video signal and a real time video signal of the plurality of video signals to a display device, content of the extracted digital video signal is different from content of the real time video signal; and wherein the sending subsystem further comprises; a third subsystem, implemented at least partially in hardware, that switches between stored digital video signals and real time video signals of the plurality of video signals in response to receiving a command to view specific video surveillance feeds. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
