Abstract

An apparatus and a method for transmitting a multimedia frame through a heterogeneous network in a broadcast system supporting a multimedia service based on an interne protocol are provided. The method includes generating header information including a frame identifier distinguishing a multimedia frame and information measuring a quality of a connection service between network layers and end-to-end network capabilities, and combining the header information and multimedia data to configure the multimedia frame.

Claims

1. A method of configuring a multimedia frame to be transmitted through a heterogeneous network in a broadcast system supporting a multimedia service based on an internet protocol, the method comprising:

generating header information including a frame identifier identifying a multimedia frame and information measuring a quality of a connection service between network layers and end-to-end network capabilities; and

combining the header information and multimedia data to configure the multimedia frame,

wherein the information on the quality of the connection service between the network layers comprises media access abstract information and type information of a media access unit,

wherein the type information of the media access unit comprises information on a bit rate, a delay degree, a capability level, and a relation with another multimedia frame, and

wherein the media access abstract information comprises a maximum end-to-end delay time and an access unit loss rate.

2. The method as claimed in claim 1, wherein, when the multimedia frame is configured, the frame identifier is assigned based on the existence of a fragment of the multimedia data.

3. The method as claimed in claim 1, wherein the header information further comprises information on a length of a datagram measured in a unit of bytes.

4. An apparatus of configuring a multimedia frame to be transmitted through a heterogeneous network in a broadcast system supporting a multimedia service based on an internet protocol, the apparatus comprising:

a multimedia data generator for generating multimedia data according to a hybrid content or a hybrid service; and

a multimedia frame configuration unit for generating header information including a frame identifier identifying a multimedia frame and information measuring a quality of a connection service between network layers and end-to-end network capabilities, and for combining the header information and multimedia data to configure the multimedia frame,

wherein the information on the quality of the connection service between the network layers comprises media access abstract information and type information of a media access unit,

wherein the type information of the media access unit comprises information on a bit rate, a delay degree, a capability level, and a relation with another multimedia frame, and

wherein the media access abstract information comprises a maximum end-to-end delay time and an access unit loss rate.

5. The apparatus as claimed in claim 4, wherein, when the multimedia frame is configured, the frame identifier is assigned based on the existence of a fragment of the multimedia data.

6. The apparatus as claimed in claim 4, the header information further comprises information on a length of a datagram measured in a byte unit.

7. A subscriber terminal, comprising:

a communication unit for transmitting and receiving a multimedia frame;

a multimedia data generator for generating multimedia data according to a hybrid content or a hybrid service; and

a multimedia frame configuration unit for generating the header information, and for generating the multimedia frame based on the header information and at least a portion of the multimedia data,

wherein the header information includes a frame identifier identifying the multimedia frame and Quality of Service (QoS) information identifying a quality of a connection service between network layers and end-to-end network capabilities,

wherein the header information further comprises Media Access Unit (MAU) abstraction information,

wherein the MAU abstraction information comprises a maximum end-to-end delay time for a transmission of the multimedia frame; and

an Access Unit Loss Ratio (AULR).

8. The subscriber terminal of claim 7, wherein the header information further comprises a length of a datagram that includes the at least a portion of the multimedia data included in the multimedia frame.
