Abstract
Disclosed herein is an apparatus for receiving a multicast signal. The apparatus may include a multicast gateway configured to receive a multicast signal based on an interface from a multicast server, and a content playback configured to display a multicast service in the multicast signal. Disclosed herein is a method of receiving a multicast signal. The method may include receiving a multicast signal based on an interface from a multicast server, and displaying a multicast service in the multicast signal.
Claims11
An apparatus for receiving a signal, the apparatus comprising:
- a multicast gateway configured to receive a multicast signal from a multicast server;
- and
- a content playback configured to display a service in the multicast signal,
- wherein the multicast signal includes a multicast transport session carrying the service,
- wherein the service is processed based on a User Datagram Protocol/Internet Protocol (UDP/IP), a Generic Stream Encapsulation (GSE) protocol, and a physical layer protocol,
- wherein the signal includes Logical Layer Control (LLC) information which is based on the GSE protocol,
- wherein the LLC information includes a multicast descriptor, wherein the multicast descriptor includes source address information, destination address information, source UDP port information, and destination UDP port information.
A method of receiving a signal, the method comprising:
- receiving a multicast signal from a multicast server;
- and
- displaying a service in the multicast signal,
- wherein the multicast signal includes a multicast transport session carrying the service,
- wherein the service is processed based on a User Datagram Protocol/Internet Protocol (UDP/IP), a Generic Stream Encapsulation (GSE) protocol, and a physical layer protocol,
- wherein the signal includes Logical Layer Control (LLC) information which is based on the GSE protocol,
- wherein the LLC information includes a multicast descriptor, wherein the multicast descriptor includes source address information, destination address information, source UDP port information, and destination UDP port information.
A method of transmitting a signal, the method comprising:
- transmitting a multicast signal from a multicast server,
- wherein the multicast signal includes a multicast transport session carrying a service,
- wherein the service is processed based on a User Datagram Protocol/Internet Protocol (UDP/IP) a Generic Stream Encapsulation (GSE) protocol, and a physical layer protocol;
- and
- generating Logical Layer Control, LLC, information based on the GSE protocol,
- wherein the LLC information includes a multicast descriptor, wherein the multicast descriptor includes source address information, destination address information, source UDP port information, and destination UDP port information.
