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 internet 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 transmitting a frame in a broadcast system, the method comprising:

generating a frame comprising header information and multimedia data; and

transmitting the generated frame to a subscriber terminal over a heterogeneous network based on a motion picture experts group (MPEG) media transport (MMT) protocol,

wherein, when the generated frame supports quality of service (QoS), the header information includes type information and delay sensitivity information,

wherein the type information identifies whether a bit rate is constant or not, and the delay sensitivity information indicates a delay sensitivity of the multimedia data, and

wherein the type information and the delay sensitivity information are used for flow control over the heterogeneous network.

2. The method as claimed in claim 1, wherein a flow for transmitting the generated frame is controlled based on the type information and a flag included in the header information.

3. The method as claimed in claim 1, wherein the header information further comprises a flow label indicating a QoS requested for each flow.

4. The method as claimed in claim 1, wherein the header information further comprises information about segmentation or combination of the multimedia data.
