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.

Claims
