Abstract

Methods, systems and computer program products are described for processing a media stream. In one aspect, a method includes detecting, in a first node processing a first media stream, information in the first media stream instructing the first node to listen for a message to be received from a second node, receiving the message from the second node, and adjusting processing of the first media stream based on the received message. The second node generates and sends a message to the first node in response to detecting information in a media stream being processed instructing the second node to send a message to the first node.

Claims

1. A method for processing a media stream, the method comprising:

detecting, in a first node processing a first media stream, information in the first media stream instructing the first node to listen for a message to be received from a second node;

receiving the message from the second node; and

adjusting processing of the first media stream based on the received message.

2. The method of claim 1 wherein the second node is processing a second media stream.

3. The method of claim 2 wherein the first media stream and the second media stream are instances of a same stream.

4. The method of claim 1 wherein the detected information includes at least one of an executable instruction and a non-executable indication.

5. The method of claim 4 further comprising processing at least one of the executable instruction and the non-executable indication in the detected information to instruct the first node to at least one of establish a subscription, send a request message, and open a communication endpoint for listening for the message from the second node.

6. The method of claim 1 wherein the detecting comprises executing by the first node at least one of an instruction included in the first media stream and an instruction included in a component of the first node.

7. The method of claim 1 wherein the detected information includes information identifying at least one of message content, message format, an attribute of time relating to the receiving of the message, and the second node.

8. The method of claim 1 wherein the adjusting processing of the first media stream based on the received message is further based on at least one of a sender of the message, a content type of a portion of the message, an attribute of the first media stream, and a user.

9. The method of claim 1 wherein adjusting processing of the first media stream includes altering presentable content of the first media stream by at least one of presenting content included in the received message;

one of terminating and pausing the processing of the first media stream;

changing a rate of processing; and

altering a source of the first media stream.

10. A method for processing a media stream, the method comprising:

detecting, in a first node processing a first media stream, information in the first media stream instructing the first node to send a message to a second node;

generating the message in response to detecting the information; and

sending the message to the second node.

11. The method of claim 10 wherein the detected information includes at least one of an instruction and a non-executable indication.

12. The method of claim 10 further comprising processing the detected information to at least one of specify and evaluate an expression including a variable identifying a value based on at least one of a content of the first media stream and a received input, wherein at least one of generating the message and sending the message is based on an evaluation of the expression with the variable set to the identified value.

13. The method of claim 10 wherein the detected information includes information identifying at least one of message content, message format, an attribute of time relating to at least one of the generating of the message and the sending of the message, and the second node.

14. The method of claim 10 wherein detecting the information comprises executing by the first node at least one of an instruction included in the first media stream and an instruction included in a component of the first node.

15. The method of claim 10 wherein the second node is processing a second media stream, and wherein the message includes information for altering the processing of the second media stream.

16. A computer readable medium containing a computer program, executable by a machine, for processing a media stream, the computer program comprising executable instructions for:

detecting, in a first node processing a first media stream, information in the first media stream instructing the first node to listen for a message to be received from a second node;

receiving the message from the second node; and

adjusting processing of the first media stream based on the received message.

17. A system for processing a media stream, the system comprising:

means for detecting, in a first node processing a first media stream, information in the first media stream instructing the first node to listen for a message to be received from a second node;

means for receiving the message from the second node; and

means for adjusting processing of the first media stream based on the received message.

18. A system for processing a media stream, the system comprising:

a media processing module configured to detect, in a first node processing a first media stream, information in the first media stream instructing the first node to listen for a message to be received from a second node;

a message receiver configured to receive the message from the second node; and

a content handler component configured to adjust processing of the first media stream based on the received message.

19. The system of claim 18 wherein the second node is processing a second media stream.

20. The system of claim 18 wherein the first media stream and the second media stream are instances of a same stream.

21. The system of claim 18 wherein the detected information includes at least one of an executable instruction and a non-executable indication.

22. The system of claim 21 wherein the content handler component is configured to process at least one of the executable instruction and the non-executable indication in the detected information to instruct the first node to at least one of establish a subscription, send a request message, and open a communication endpoint for listening for the message from the second node.

23. The system of claim 18 wherein the media processing module is configured to execute at least one of an instruction included in the first media stream and an instruction included in a component of the first node.

24. The system of claim 18 wherein the detected information includes information identifying at least one of message content, message format, an attribute of time relating to the receiving of the message, and the second node.

25. The system of claim 18 wherein the content handler is configured to adjust processing of the first media stream based on at least one of a sender of the message, a content type of a portion of the message, an attribute of the first media stream, and a user.

26. The system of claim 18 wherein the content handler is further configured to alter presentable content of the first media stream by at least one of presenting content included in the received message;
