Digital security surveillance system
First Claim
1. A method for storage and display of video surveillance data, comprising the steps of:
- receiving a plurality of video signals from video surveillance feeds in a video surveillance system;
storing each video signal on a storage device as a digital video signal;
accepting a command from a user to view a specific video surveillance feed;
extracting a digital video signal for the specific video surveillance feed from the storage device;
sending the extracted digital video signal to a display device; and
wherein the sending step further comprises;
switching between stored digital 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.
