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, the header information including first information indicating a type of bit rate and second information including a flag; and

transmitting the frame to a subscriber terminal through a heterogeneous network,

wherein the first information identifies whether the type of bit rate is constant, and the second information indicates whether a loss is allowed, and

wherein the flow control for transmitting the frame is based on the first information and the second information.
