Duplicating switch for streaming data units to a terminal using different communication protocols
First Claim
Patent Images
1. A method of streaming data units to a user terminal at a duplicating switch, the method comprising:
- receiving a stream of content encoded using a first communications protocol;
decoding the stream of content from the first communications protocol;
using the duplicating switch to store the decoded stream of content;
receiving a request from the user terminal for content corresponding to the stored stream, wherein the user terminal is accessible using a second communications protocol that is different from the first communications protocol; and
in response to the received request, using the duplicating switch to duplicate the stored stream of content by;
duplicating the stored stream of content,encoding the duplicated stream of content using the second communications protocol, andforwarding the encoded duplicated stream to the user terminal using the second communications protocol.

Abstract
Streaming to a terminal by using a duplicating switch to receive a stream of data units, using the duplicating switch to store content from the stream, using the duplicating switch to generate a second stream that incorporates the content that was stored and address information corresponding to more than one terminal whose addressing information was not part of the first stream, and using the duplicating switch to make the second stream of data units available to two or more terminals.

1. A method of streaming data units to a user terminal at a duplicating switch, the method comprising:
-
receiving a stream of content encoded using a first communications protocol; decoding the stream of content from the first communications protocol; using the duplicating switch to store the decoded stream of content; receiving a request from the user terminal for content corresponding to the stored stream, wherein the user terminal is accessible using a second communications protocol that is different from the first communications protocol; and in response to the received request, using the duplicating switch to duplicate the stored stream of content by; duplicating the stored stream of content, encoding the duplicated stream of content using the second communications protocol, and forwarding the encoded duplicated stream to the user terminal using the second communications protocol. - View Dependent Claims (2, 3, 4, 5, 6)

7. A duplicating switch comprising:
-
a first communications interface structured and arranged to receive a stream of content encoded using a first communications protocol and decode the stream of content from the first communications protocol; a storage processor structured and arranged to store the decoded stream of content; a duplicating processor structured and arranged to duplicate the stored stream of content in response to a request from a user terminal for content corresponding to the stored stream; and a second communications interface structured and arranged to; receive the request from the user terminal for content corresponding to the stored stream, wherein the user terminal is accessible using a second communications protocol that is different from the first communications protocol, encode the duplicated stream of content using the second communications protocol, and forward the encoded duplicated stream to the user terminal using the second communications protocol. - View Dependent Claims (8, 9, 10, 11, 12)

13. A duplicating switch comprising:
-
means for receiving a stream of content encoded using a first communications protocol; means for decoding the stream of content from the first communications protocol; means for using the duplicating switch to store the decoded stream of content; means for receiving a request from a user terminal for content corresponding to the stored stream, wherein the user terminal is accessible using a second communications protocol that is different from the first communications protocol; and in response to the received request, means for using the duplicating switch to duplicate the stored stream of content by; duplicating the stored stream of content, encoding the duplicated stream of content using the second communications protocol, and forwarding the encoded duplicated stream to the user terminal using the second communications protocol.
