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.
Claims8
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.
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.
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).
