Abstract

The present invention is directed to various methods and systems for analysis and processing of video and audio signals from a plurality of sources in real-time or off-line. According to some embodiments of the present invention, analysis and processing applications are dynamically installed in the processing units.

Claims

1. A system comprising:

an application bank of content-analysis applications;

two or more video processing units, each having respective one or more of the content-analysis applications installed therein, each of the video processing units coupled to a respective video sensor and receiving video data from the video sensor over Internet Protocol (IP); and

a control unit separate from said video processing units, said control unit having installed therein a set of rules, the control unit coupled to the video processing units and to the application bank,

wherein upon receiving a notification from one of the video processing units that one of the applications installed therein detects a first predefined condition based on content-analysis processing of at least a portion of the video data, the control unit automatically and dynamically instructs the application bank to install in real-time, at least another one of the content-analysis applications into at least one of the processing units based on the set of rules;

wherein the application bank includes at least two of a video movement-detecting application, a video based people counting application, a face detection and recognition application, a voice detection and recognition application, an object detection application or a recognition and surveillance application, and wherein upon receiving said notification, the control unit automatically and dynamically instructs the application bank to install in real-time, at least two of said video movement-detecting application, said video based people counting application, said face detection and recognition application, said voice detection and recognition application, said object detection application, and said recognition and surveillance applications into at least one of the processing units based on the set of rules.

2. The system of claim 1 comprising:

an audio processing unit coupled to an audio sensor having one or more of the content-analysis applications installed therein, the audio processing unit coupled to a respective audio sensor and receives audio data from the audio sensor over Internet Protocol (IP).

3. The system of claim 2, wherein upon receiving a notification from the audio processing unit that one of the applications installed therein detects a predefined condition based on content-analysis processing of at least a portion of the audio data, the control unit automatically and dynamically instructs the application bank to install in real-time, at least another one of the content-analysis applications into at least one of the processing units based on the set of rules.

4. The system of claim 2, wherein one of the rules is to install a face recognition application upon identification of the voice of a particular person.

5. The system of claim 1 further comprising:

at least one additional processing unit coupled to a sensor, the sensor being a smoke sensor, a fire sensor, a motion detector, a sound detector, a presence sensor, a movement sensor, a volume sensor or a glass breakage sensor.

6. The system of claim 1, wherein the application bank further comprises at least a conversion of speech to text application or a video compression application, and wherein upon receiving said notification, the control unit automatically and dynamically instructs the application bank to install in real-time, at least one of said conversion of speech to text application or said video compression application into at least one of the processing units based on the set of rules.

7. The system of claim 1 further comprising a database to store indexing data associated with the video data.

8. The system of claim 1, wherein the application bank, the control unit and the processing units are all coupled via a local area or a wide area network.

9. The system of claim 1, wherein the video processing units are embedded in the video sensors.

10. The system of claim 1, wherein upon receiving another notification from one of the video processing units that one of the applications installed therein detects a second predefined condition based on content-analysis processing of at least a portion of the video data, the control unit automatically instructs one of the processing units to activate or deactivate one of the content-analysis applications already installed therein.

11. The system of claim 1, wherein one of the rules is to install a face recognition application upon detection of a movement.

12. The system of claim 1, wherein one of the rules is to install a video compression application upon identification of a particular person.
