Abstract

A transmitting apparatus and an operating method for the apparatus in a multimedia system are provided. The operating method includes inputting at least one network layer packet, generating a link layer packet based on the at least one network layer packet, and transmitting the link layer packet. The link layer packet includes a header including information indicating a packet type of the at least one network layer packet, information indicating whether the link layer packet includes a single network layer packet, and information indicating an identifier related to the at least one network layer packet.

Claims

1. A method of transmitting a packet by a transmitting apparatus in a broadcasting system, the method comprising:

identifying at least one network layer packet;

generating a link layer packet based on the at least one network layer packet; and

transmitting the link layer packet,

wherein the link layer packet comprises a header and a payload, the header including a base header,

wherein the base header includes packet type information indicating a type of the at least one network layer packet and payload configuration information indicating a configuration of the payload,

wherein the payload configuration information is set to one of;

a first value indicating that the payload includes a single network layer packet and information following the payload configuration information is header mode information, and

a second value indicating that the payload includes a part of a network layer packet or a plurality of network layer packets and information following the payload configuration information is segmentation concatenation information, and

wherein the header mode information indicates whether a first additional header is present.

2. The method of claim 1, wherein the segmentation concatenation information is set to one of:

a first value indicating that the payload includes the part of the network layer packet and a second additional header is present, and

a second value indicating that the payload includes the plurality of network layer packets and a third additional header is present.

3. The method of claim 2, wherein the first additional header, the second additional header and the third additional header include flag information indicating whether an optional header for sub-stream identification is present.

4. The method of claim 3, wherein the second additional header further includes segment sequence number information indicating an order of a segment carried by the link layer packet and last segment indicator information indicating whether the segment is a last segment.

5. The method of claim 4, wherein the third additional header further includes information indicating a number of the plurality of network layer packets included in the link layer packet and component length information indicating a length of each of the plurality of network layer packets.

6. A transmitting apparatus of transmitting a packet in a broadcasting system, the transmitting apparatus comprising:

a transceiver configured to receive and transmit data; and

at least one processor configured to;

identify at least one network layer packet,

generate a link layer packet based on the at least one network layer packet, and

transmit the link layer packet,

wherein the link layer packet comprises a header and a payload, the header including a base header,

wherein the base header includes packet type information indicating a type of the at least one network layer packet and payload configuration information indicating a configuration of the payload,

wherein the payload configuration information is set to one of;

a first value indicating that the payload includes a single network layer packet and information following the payload configuration information is header mode information, and

a second value indicating that the payload includes a part of a network layer packet or a plurality of network layer packets and information following the payload configuration information is segmentation concatenation information, and

wherein the header mode information indicates whether a first additional header is present.

7. The transmitting apparatus of claim 6, wherein the segmentation concatenation information is set to one of:

a first value indicating that the payload includes the part of the network layer packet and a second additional header is present, and

a second value indicating that the payload includes the plurality of network layer packets and a third additional header is present.

8. The transmitting apparatus of claim 7, wherein the first additional header, the second additional header and the third additional header include flag information indicating whether an optional header for sub-stream identification is present.

9. The transmitting apparatus of claim 8, wherein the second additional header further includes segment sequence number information indicating an order of a segment carried by the link layer packet and last segment indicator information indicating whether the segment is a last segment.

10. The transmitting apparatus of claim 8, wherein the third additional header further includes information indicating a number of the plurality of network layer packets included in the link layer packet and component length information indicating a length of each of the plurality of network layer packets.
