Abstract

A system and method for directing a media stream includes a packet reader reading and correlating a packet with the media stream and readdressing the packet to a variable address associated with the media stream. The variable address may be changed in accordance with predefined criteria or in response to commands issued by the intended recipient of the packet.

Claims

1. A method for directing a media stream comprising reading and correlating a packet with the media stream and readdressing the packet to a variable address associated with the media stream.

2. The method according to claim 1, further comprising detecting the start of a media stream transmission and instructing a source of the transmission to address data packets to an intermediate network entity.

3. The method according to claim 1, further comprising checking a readdressing indicator and readdressing the packet if the indicator so indicates.

4. The method according to claim 1, further comprising checking the variable address and readdressing the packet if the variable address is different from a destination address in the packet.

5. The method according to claim 1, further comprising setting the variable address to an address of a network entity selected from the group consisting of a storage device, a coder/decoder, a code conversion device, a media format conversion device, a multicaster, an encryption device, a computing device, a media presentation device, a firewall authenticator, a firewall penetration device, a firewall negotiation device, a firewall gatekeeper and a communicationl failure recovery device.

6. The method according to claim 5, further comprising receiving a signal containing a destination address and setting the variable address to the received address.

7. A system for directing a media steam comprising an intermediate network entity adapted to receive a data packet and to correlate the packet with the media stream, a readdressing module adapted to readdress the data packet to a variable address associated with the media stream.

8. The system according to claim 7, further comprising a media stream detection module adapted to detect the start of a media stream and to instruct a source of the media stream to address the media stream'"'"'s packets to the intermediate network entity.

10. The system according to claim 8, further comprising a data table containing an address of at least one of the network entities listed in claim 9.

9. The system according to claim 9, further comprising one or more of the network entities selected from the group consisting of a storage device, a coder/decoder, a code conversion device, a media format conversion device, a multicaster, an encryption device, a computing device, a media presentation device, a firewall authenticator, a firewall penetration device, a firewall negotiation device, a firewall gatekeeper and a communication failure recovery device.

11. An article comprising:

a storage medium having stored thereon instructions, that, when executed by a computing platform, cause the computing platform to read and correlate a packet header with a media stream and readdress the packet to a variable address associated with the media stream.

12. The article of claim 11, further comprising instructions when executed cause the platform to detect the start of a media stream transmission and cause a source of the transmission to address data packets to the platform.

13. The article of claim 12, further comprising instructions when executed cause the platform to set the variable address to an address of a network entity selected from the group consisting of a storage device, a coder/decoder, a code conversion device, a media format conversion device, a multicaster, an encryption device, a computing device, a media presentation device, a firewall authenticator, a firewall penetration device, a firewall negotiation device, a firewall gatekeeper and a communication failure recovery device.

14. The article of claim 13, further comprising instructions when executed cause the platform to receive a signal containing a destination address and to set the variable address to the received address.
