Abstract
A method for encoding a packet in a broadcasting system supporting an Internet Protocol (IP)-based multimedia service is provided. The method includes dividing a data stream into data payloads, generating a Motion Picture Expert Group (MPEG) Media Transport (MMT) packet by adding a first header to each of the data payloads, and generating a source packet by adding an MMT packet header to the MMT packet and performing Forward Error Correction (FEC) encoding on the header-added MMT packet. The MMT packet header includes type information of the MMT packet.
Claims8
A method for transmitting a transport packet in a communication system, the method comprising:
- generating a transport packet including media data;
- applying a forward error correction (FEC) scheme to the transport packet;
- and
- transmitting the transport packet,
- wherein the transport packet includes a header including FEC type information and a payload, the FEC type information indicating a type of the FEC scheme for the transport packet,
- wherein the FEC type information is set to a first value indicating that the transport packet is a transport packet not including a source payload ID, in case that the FEC scheme is applied to the transport packet without adding the source payload ID to the transport packet, and
- wherein the FEC type information is set to a second value indicating that the transport packet is a transport packet including the source payload ID, in case that the FEC scheme is applied to the transport packet with adding the source payload ID to the transport packet, the source payload ID being added after the payload and at the end of the transport packet.
An apparatus for transmitting a transport packet in a communication system, the apparatus comprising:
- a controller configured to:
- generate a transport packet including media data, and
- apply a forward error correction (FEC) scheme to the transport packet,
- a transmitter configured to transmit the transport packet,
- wherein the transport packet includes a header including FEC type information and a payload, the FEC type information indicating a type of the FEC scheme for the transport packet, and
- wherein the FEC type information is set to a first value indicating that the transport packet is a transport packet not including a source payload ID, in case that the FEC scheme is applied to the transport packet without adding the source payload ID to the transport packet, and
- wherein the FEC type information is set to a second value indicating that the transport packet is a transport packet including the source payload ID, in case that the FEC scheme is applied to the transport packet with adding the source payload ID to the transport packet, the source payload ID being added after the payload and at the end of the transport packet.
A method for receiving a transport packet in a communication system, the method comprising:
- receiving a transport packet including media data;
- and
- decoding the transport packet based on a forward error correction (FEC) scheme,
- wherein the transport packet includes a header including FEC type information and a payload, the FEC type information indicating a type of the FEC scheme for the transport packet,
- wherein the FEC type information is set to a first value indicating that the transport packet is a transport packet not including a source payload ID, in case that the FEC scheme is applied to the transport packet without adding the source payload ID to the transport packet, and
- wherein the FEC type information is set to a second value indicating that the transport packet is a transport packet including the source payload ID, in case that the FEC scheme is applied to the transport packet with adding the source payload ID to the transport packet, the source payload ID being added after the payload and at the end of the transport packet.
An apparatus for receiving a transport packet in a communication system, the apparatus comprising:
- a receiver configured to receive a transport packet including media data;
- and
- a decoder configured to decode the transport packet based on a forward error correction (FEC) scheme,
- wherein the transport packet includes a header including FEC type information and a payload, the FEC type information indicating a type of the FEC scheme for the transport packet,
- wherein the FEC type information is set to a first value indicating that the transport packet is a transport packet not including a source payload ID, in case that the FEC scheme is applied to the transport packet without adding the source payload ID to the transport packet, and
- wherein the FEC type information is set to a second value indicating that the transport packet is a transport packet including the source payload ID, in case that the FEC scheme is applied to the transport packet with adding the source payload ID to the transport packet, the source payload ID being added after the payload and at the end of the transport packet.
