Abstract

A system and method for the late-biding of time-based media in real-time. With late binding, the sender may create time-based media before or at the same time an active delivery route to the recipient is discovered. As soon as the route becomes available, the media is transmitted. The existing DNS and email infrastructure is possibly used for route discovery, while any real-time transmission protocol may be used for the actual delivery of the media. “Progressive” emails may also be used for the real-time delivery of time-based media.

Claims

1. A method performed at a node on a network for progressively receiving, storing and forwarding a video message from a sender to a recipient over the network, comprising:

receiving at the node an identifier contained in a message header of the video message, the identifier identifying a recipient of the video message;

ascertaining an address for identifying a communication device associated with the recipient on the network from the identifier contained in the message header of the video message;

progressively receiving video media contained in a message body of the video message as the video media is created and progressively transmitted by the sender;

progressively and persistently storing the video media contained in the message body as the video media is received at the node; and

starting progressive transmission of the video media of the video message to the recipient as the video media is received and persistently stored, before the video media contained in the message body is complete, using a delivery route for delivering the video media over the network to the communication device associated with the recipient that is discovered using the ascertained address for the communication device.

2. The method of claim 1, wherein starting the progressive transmission of the video media of the video message to the recipient further comprises progressively transmitting the video media over the network as one or more hops along the delivery route to the communication device associated with the recipient is/are discovered.

3. The method of claim 1, wherein the address of the communication device is ascertained from a lookup result of the identifier that is either:

(i) an active lookup result of the identifier associated with the recipient;

or

(ii) a cached result of a previous lookup of the identifier.

4. The method of claim 1, wherein the identifier is defined by the sender in one of the following ways:

(i) by selecting the recipient from a list of contacts;

(ii) the manual entry of the identifier of the recipient;

(iii) implementing a reply function in response to the receipt of a previous message;

or

(iv) selection of a conversation in which the recipient is a participant.

5. The method of claim 1, further comprising, after the start of the progressive transmission, progressively transmitting the video media to the communication device associated with the recipient in real-time as the video media is created by the sender using a sending communication device.

6. The method of claim 1, wherein the identifier is assigned to the recipient and is used to uniquely identify the recipient among a community of users.

7. The method of claim 1, further comprising enabling the recipient to access the video message from persistent storage on the network at a time after the video message is created and sent by the sender.

8. The method of claim 1, wherein the start of the progressive transmission of the video media of the video message by the node to the communication device associated with the recipient supports the near real-time delivery of the video media of the video message to the recipient without first requiring a synchronous connection over the network between a sending communication device associated with the sender and the communication device associated with the recipient.

9. The method of claim 1, wherein the message body is dynamic having a duration that dynamically extends to contain the video media of the video message for the duration of the video message.

10. The method of claim 1, wherein the video message is created and sent to a plurality of recipients and each of the plurality of recipients is targeted for receipt of the video message by inserting a unique identifier for each of the plurality of recipients in the message header respectively.

11. The method of claim 1, wherein the progressive transmission of the video media of the video message enables the recipient to view the video media of the video message on the communication device substantially live, as the video media is created, but delayed by the latency of the network.

12. The method of claim 1, wherein ascertaining the address for the identifying the recipient further comprises ascertaining a current IP address on the network for the communication device associated with the recipient.

13. The method of claim 1, further comprising at least separately processing the message header and the message body of the video message at the node on the network by ascertaining the address for identifying the communication device associated with the recipient using the identifier in the message header before receiving the video media contained in the message body in its entirety.

14. The method of claim 1, wherein the start of the progressive transmission of the video media of the video message by the node enables the recipient to view the video media of the video message on the communication device associated with the recipient substantially live as the video media is created and transmitted by the sender.

15. The method of claim 1, wherein the video message is sent by the sender using a sending communication device without having to first notify the recipient or to receive agreement from the recipient to send the video message.

16. An application, embedded in a non-transitory computer readable medium and intended to be executed on a communication device connected to a network, the application configured to:

receive input from a user for initiating creation of a video message to a recipient;

create, in response to the received input from the user, the video message on the communication device, the video message having a message header containing an identifier associated with the recipient of the video message and a message body for transporting video media associated with the video message;

transmit the message header to a node on the network after the identifier is defined, the node on the network using the identifier to ascertain an address on the network for a second communication device associated with the recipient from the identifier; and

progressively transmit the video media of the message body to the node on the network, as the video media is created and added to the message body, so that the node can progressively transmit the video media of the video message, as the video media is received at the node, to the recipient over the network using a delivery route to the second communication device that is discovered using the ascertained address and without first establishing an end-to-end connection over the network between the communication device and the second communication device associated with the recipient before the transmission starts,

wherein the message header containing the identifier associated with the recipient of the video message is transmitted to the node on the network before the video media added to the message body is complete.

17. The application of claim 16, further configured to progressively transmit the video media in the message body through the node to the second communication device associated with the recipient as the video media is created and as one or more hops on the network is/are discovered using the ascertained address.

18. The application of claim 16, further configured to use an IP transmission protocol that supports real-time communication for the progressive transmission of the video media of the video message.

19. The application of claim 16, wherein the identifier uniquely identifies the recipient within a community of users on the network.

20. The application of claim 16, wherein the address of the second communication device is ascertained from a lookup result of the identifier.

21. The application of claim 16, wherein the identifier is a non-IP address identifier that is resolved into an IP address for the second communication device on the network.

22. The application of claim 16, further configured to define the identifier in accordance with one of the following:

(i) in response to a selection of the recipient from a list of contacts;

(ii) in response to a manual entry of a name associated with the recipient;

or

(iii) by selecting a reply function in response to a previous message.

23. The application of claim 16, further configured to transmit the video message to the recipient over the network as the video media is created so that the recipient can render the video media in real-time at the second communication device.

24. The application of claim 16, further configured to progressively receive over the network at the communication device an incoming video message.

25. The application of claim 24, further configured to selectively enable rendering of the video media of the incoming video message in both:

(i) a real-time mode as the video media of the incoming video message is progressively received; and

(ii) in a time-shifted mode by retrieving and rendering the video media of the incoming video message from storage.

26. The application of claim 16, further configured to start the progressive transmission of the video media of the video message to the node before the delivery route to the second communication device is known.

27. The application of claim 16, further configured to start the progressive transmission of the video media of the video message to the node independent of the node on the network determining the delivery route to the second communication device.

28. The application of claim 16, further configured to start the progressive transmission of the video media of the video message to the node regardless if the second communication device is available or is not available on the network.

29. The application of claim 16, further configured to at least separately process the message header and the message body of the video message at the communication device by transmitting the identifier in the message header to the node before the video media contained in the message body is complete.

30. The application of claim 16, wherein the application is further configured to enable the sender to send the video message using the communication device without having to first notify the recipient or receive agreement from the recipient to send the video message.
