## Abstract

A method of operating a transmitting apparatus in a multimedia system is provided. The 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, wherein the link layer packet includes a header including 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

### Claim 1

A method of operating a transmitting apparatus in a broadcasting system, the method comprising:
identifying at least one network layer packet;
generating at least one link layer packet based on the at least one network layer packet; and
transmitting the at least one link layer packet,
wherein a first link layer packet of the at least one link layer packet includes a header and a payload,
wherein the header comprises a base header including payload configuration information indicating a configuration of the payload,
wherein when the payload configuration information is set as a first value, the payload configuration information indicates that the payload carriers a single network layer packet and header mode information is included in the base header, the header mode information indicating whether an additional header for the single network layer packet is included in the header,
wherein the header further comprises an extension header including sub-stream identification information when flag information included in the additional header indicates that the sub-stream identification information is included in the extension header
wherein the sub-stream identification information is used to filter a packet stream in a link layer level, the packet stream including one or more of the at least network layer packet.

### Claim 2 (depends on 1)

The method of claim 1, wherein when the payload configuration information is set as a second value, the payload configuration information indicates that the payload carries a plurality of network layer packets or a part of a network layer packet and segmentation/concatenation information is included in the base header.

### Claim 3 (depends on 2)

The method of claim 2,
wherein if the segmentation/concatenation information is set as a first value, the segmentation/concatenation information indicates that the payload carries the part of the network layer packet and an additional header for segmentation is included in the header, and
wherein when the segmentation/concatenation information is set as a second value, the segmentation/concatenation information indicates that the payload carries the plurality of the network layer packets and an additional header for concatenation is included in the header.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
identifying link layer signaling information; and
generating at least one first link layer packet based on the link layer signaling information,
wherein the link layer signaling information includes mapping information between one or more packet streams and one or more sub-stream identification information corresponding to the one or more packet streams.

### Claim 5 (depends on 4)

The method of claim 4,
wherein the mapping information includes source IP address information, destination IP address information, source UDP port information and destination UDP port information, and sub-stream flag information for each packet stream, and
wherein a presence of sub-stream indication information for the each packet stream is determined based on the sub-stream flag information for the each packet stream.
