Abstract

In accordance with one aspect of the present invention, a method for monitoring usage of a channel, including monitoring upstream information, and determining usage of the channel in response to the monitoring is disclosed. In accordance with another aspect of the present invention, a service module for monitoring usage of a channel includes a data input operative to monitor upstream information, and a processor that determines usage of the channel in response to the data input is disclosed. In accordance with another aspect of present invention, the method and module also include monitoring video delivery path performance and detecting potential denial-of-service (DoS) attacks to video servers is disclosed.

Claims

1. A method for determining usage of a channel, comprising:

monitoring upstream information; and

determining the usage of a channel in response to the monitoring of the upstream information.

2. The method for determining usage of a channel of claim 1, wherein:

monitoring the upstream information includes non-detrimentally monitoring packets of information from a device to a server over the internet.

3. The method for determining usage of a channel of claim 1, wherein:

the upstream information includes packets including a subscriber upstream packet operative to describe at least one of;

a subscriber channel tuning dynamic, a video on demand viewing activity, a list of at least one popular channel, a channel changing frequency, a channel changing time, a household-specific IPTV usage, and content viewing information.

4. The method for determining usage of a channel of claim 1, wherein:

monitoring includes detecting at least one control packet that is addressed to a video-server.

5. The method for determining usage of a channel of claim 1, wherein:

monitoring includes querying at least one subscriber device.

6. The method for determining usage of a channel of claim 1, wherein:

determining includes performance of a math-based analysis having an estimation accuracy and a probing interval.

7. A method for determining video delivery path performance, comprising:

detecting upstream information indicative of a loss of packets;

determining from the detected upstream information the video delivery path performance.

8. The method for determining video deliver path performance of claim 7 further comprising determining denial of service (DoS) attacks to a server.

9. A service module, comprising:

a data input operative to monitor upstream information, the data input being further operative to non-detrimentally monitor at least one packet of information from a user-associated device to a server over the internet.

10. The service module of claim 9 further comprising a processor that determines one of (i) video delivery path performance, (ii) denial of service, and (iii) channel usage.

11. The service module of claim 9, wherein:

the data input is further operative to non-detrimentally monitor at least one packet of information from a user-associated device to a server over the internet.

12. The service module of claim 11, wherein:

the data input is further operative to monitor at least one subscriber upstream packet operative to describe at least one of;

a subscriber channel tuning dynamic, a video on demand viewing activity, a list of at least one popular channel, a channel changing frequency, a channel changing time, a household-specific IPTV usage, and content viewing information.

13. The service module of claim 9, wherein:

the data input is further operative to query at least one client.

14. The service module of claim 9, further comprising:

a processor operative to perform a math-based analysis having an estimation accuracy and a probing interval.

15. A computer readable medium having a set of instructions operative to cause a computer to execute a method, the method comprising:

detecting upstream information sent from a device associated with a subscriber over an internet; and

determining from the detected upstream a parameter relating to delivery of an information over the internet to the subscriber.

16. The computer readable medium of claim 15 wherein the parameter is selected from a group consisting of (i) a subscriber channel tuning dynamic, (ii) a video on demand viewing activity, (iii) a channel changing activity, (iv) a channel changing time, (v) a channel usage, (vi) a user-specific IPTV usage, (vii) rating of a plurality of channels, (viii) quality of service, (ix) a denial of service, and (x) peak times for IPTV usage.

17. The computer readable medium of claim 15 further comprising sending a query to the device associated with the subscriber.

18. The computer readable medium of claim 15 wherein the device associated with the subscriber is one of (i) a set-top-box and (ii) an FTTN device.

19. A system for monitoring a network that provides video contents to a plurality of end users, wherein the network includes an end user device associated with each end user in the plurality of end users, and at least one server that receives an upstream information from the end user associated device over the internet, comprising:

an interface between each end user associated device and the server that detects upstream information sent by the each end user device and determines from the detected signals a parameter relating to the video contents.

20. The system of claim 19 wherein the interface includes a program that passively detects the upstream information.

21. The system of claim 19 wherein the interface further determines when the detected upstream information is outside a predetermined level and sends packets to the server that indicate an unacceptable service level.

22. The system of claim 19 wherein the parameter is one of:

(i) channel usage by at least one of the end users, (ii) duration of use of channels by at least one of the end users, (iii) a level of video content delivery path performance that is below a predetermined level, and (iv) potential denial-of-service (DoS) attacks to video servers.
