Audio/Video monitoring service using set-top boxes and application servers
An audio/video monitoring system is disclosed, comprising a combination of one or more set-top boxes and application servers in a service provider's network. The set-top boxes and applications services are part of a multiple services operator's (MSO) network, such as that of a cable company. Cameras and/or microphones which are directly connected to a set-top box are the sources of media signals, which the set-top box transmits to an application server. The application server continually receives the media signals from one or more set-top boxes, and determines which subset of the received media signals to forward to a selected output device, such as a television connected to another set-top box or a cellular telephone. The application server then forwards media signals of interest to the output device, such as when motion or a loud noise is detected in a media signal received from the set-top box or boxes.
1. A method comprising:
receiving, at a server, running an Open Cable Application Platform (“OCAP”) compliant application program:
i) a first identifier of an input device, the input device being situated at a first customer premises equipment location and being capable of generating a first media signal,
ii) a second identifier of an output device, the output device being capable of presenting the first media signal to a user, and
iii) a trigger condition for evaluating the first media signal, wherein the trigger condition is based upon calendrical time and the server being situated at a location that is different from the first customer premises equipment location;
receiving, at the server, the first media signal originating at the input device represented by the first identifier; and
when the trigger condition is met, the OCAP compliant application program transmitting the first media signal to:
the output device represented by the second identifier during a first predefined period of time, wherein the first predefined period of time is defined in a calendar; and
an output device represented by a third identifier during a second predefined period of time, wherein the second predefined period of time is defined in the calendar.
2. The method of claim 1 wherein the input device is a camera and the output device is one of a video monitor and a television.
3. The method of claim 1 wherein the input device is a camera and the output device is a cellular telephone.
4. The method of claim 1 further comprising mapping the second identifier to a predetermined address, wherein transmitting the first media signal comprises routing it to the predetermined address.
5. The method of claim 4 wherein the predetermined address is based upon a telephone number.
6. The method of claim 4 wherein the predetermined address is based upon an Internet Protocol address.
7. The method of claim 1 , wherein the input device is only a microphone and the output device represented by the second identifier is a television and wherein the first media signal only preempts an audio content of the television while not preempting a video signal being displayed on the television.
8. A method comprising:
receiving, at a server, running an Open Cable Application Platform (“OCAP”) compliant application program: i) a first identifier of a predetermined output device and ii) a media signal from a set-top box, the output device being situated at a different location than the customer premises equipment location of the set-top box;
determining by the OCAP compliant application program whether a trigger condition has been met, wherein the trigger condition is for evaluating the media signal and is based upon calendrical time; and
when the trigger condition has been met, the OCAP compliant application program transmitting the media signal to the output device represented by the first identifier during a first predefined period of time and to an output device represented by a second identifier during a second predefined period of time, wherein the first predefined period of time is defined in a calendar and wherein the second predefined period of time is defined in the calendar.
9. The method of claim 8 wherein the output device is a cellular telephone.
10. The method of claim 8 wherein the output device is one of a video monitor and a television.
11. The method of claim 8 wherein the media signal conveys video content, and wherein the trigger condition relates to whether motion has been detected in the video content.
12. The method of claim 8 wherein the media signal conveys audio content, and wherein the trigger condition relates to whether a predetermined characteristic of the audio content has exceeded a threshold.
13. The method of claim 12 wherein the predetermined characteristic is signal level.
14. The method of claim 8 further comprising selecting the output device represented by the first identifier, from a plurality of output devices that are capable of receiving the media signal, wherein the selecting is based upon calendrical time.
15. The method of claim 8 wherein the determining of whether the trigger condition has been met is performed at the set-top box.
16. The method of claim 8 wherein the determining of whether the trigger condition has been met is performed at the server.
17. The method of claim 8 , wherein the output device represented by the second identifier is a television and wherein the media signal only preempts an audio content of the television while not preempting a video signal being displayed on the television.
