Patent number: 10701187Abstract: A protocol converter includes a processor configured to receive a request for content from a client system. The processor is further configured to determine if the protocol converter is currently receiving the content through the multicast session, and join the multicast session if the protocol converter is not currently receiving the content. Additionally, the processor is configured to receive the content as an end point of the multicast session, format the content for communication to the client system, and provide content to the client system in a communication separate from the multicast session. Receiving the content as an end point of the multicast session can include terminating the application layer protocol used by the multicast session. Additionally, formatting the content can include re-encapsulating the content as hypertext transport protocol (HTTP) with an appropriate content-type.Type: GrantFiled: August 13, 2018Date of Patent: June 30, 2020Assignee: AT&T Intellectual Property I, L.P.Inventors: Alan L. Glasser, Andrew G. Gauld, John F. Lucas
