CONTENT AWARE STORAGE OF VIDEO DATA
First Claim
1. A method of implementing video storage in a video camera producing video data representing a field of view of a scene observed by the video camera, the video camera including a camera housing and is adapted for connection to a network communication system, comprising:
- defining an event of interest for detection by analysis of the video data produced by the video camera;
providing the video camera with video analytics and a mass storage unit, the video analytics and mass storage unit contained in or forming part of the camera housing;
causing the video analytics to analyze the video data produced by the video camera and detect whether there is an occurrence of the event of interest; and
storing in the mass storage unit the video data representing the field of view of the scene observed by the video camera, the stored video data including video data of a first quality and video data of a second quality, the first quality representing the occurrence in the field of view of the event of interest detected by the video analytics and the second quality representing nonoccurrence in the field of view of the event of interest detected by the video analytics.

Abstract
Video analytics and a mass storage unit are contained in a camera housing of a video camera. The video analytics analyzes video data produced by the video camera and detects whether there is an occurrence of a defined event of interest. The video data representing the field of view of the scene observed by the video camera are stored in the mass storage unit. The stored video data include video data of first and second qualities. The first quality represents the occurrence in a field of view of the video camera of the defined event of interest detected by the video analytics. The second quality represents the nonoccurrence in the field of view of the defined event of interest detected by the video analytics. Storing video data of first and second qualities reduces system storage capacity demands.

20. A method of reducing video data storage and network bandwidth requirements of a distributed network video surveillance system that includes network communication paths between network video imaging devices and network video data stores, the network video imaging devices producing video data representing fields of view of scenes under observation by the video imaging devices, and the network video data stores storing video information corresponding to the video data produced by the network video imaging devices, comprising:
-
associating with each of multiple ones of the network video imaging devices a content-aware video data storage system that is capable of selective storage of video data produced by its associated network video imaging device, the content-aware video data storage system including video analytics that analyzes the content of the video data and local video data stores that store portions of the video data in response to the analysis by the video analytics; and delivering from the content-aware video data storage system of each of the multiple network video imaging devices, through the network communication paths, to the network video data stores, video data corresponding to the portions of video data stored in the local video data stores to provide a managed amount of video data representing at a specified quality level the fields of view of the scenes, the managed amount of the video data consuming substantially less network bandwidth and fewer data storage resources than those which would be consumed by delivery to the network video stores the video data produced by the network video imaging devices at the specified quality level and in the absence of analysis by the video analytics. - View Dependent Claims (21)
