摘要： A method for encoding a packet in a broadcasting system supporting an Internet Protocol (IP)-based multimedia service is provided. The method includes dividing a data stream into data payloads, generating a Motion Picture Expert Group (MPEG) Media Transport (MMT) packet by adding a first header to each of the data payloads, and generating a source packet by adding an MMT packet header to the MMT packet and performing Forward Error Correction (FEC) encoding on the header-added MMT packet. The MMT packet header includes type information of the MMT packet.

摘要： The present invention relates to an apparatus and a method for configuring a control message in a broadcasting system for supporting a multimedia service based on an interne protocol. To this end, control information to be recorded in a payload of a control message to be configured is generated based on a table selected from among a plurality of tables for defining the information related to the generation and consumption of a hybrid content when a message type of the control message to be configured is determined to be a type for providing information related to the generation and consumption of a hybrid content. In addition, the information related to the type of the selected table is recorded in an optional field of the control message to be configured.

摘要： An apparatus and a method for transmitting multimedia data in a broadcast system are provided. A method for constructing a payload for a multimedia frame to be transmitted via a heterogeneous network, in a broadcast system that supports an Internet protocol-based multimedia service, includes dividing the data so as to transmit data of at least one media type and constructing a data region based on each datum of the divided data, constructing a header region including information on the state of the data contained in the data region and/or information on the data region, and combining the data region and the header region to construct a payload for the multimedia frame.

摘要： The present invention relates to a method of playing back a bitstream for transferring a group of pictures, the method comprising the steps of: parsing, when a random access occurs in a first picture, a network abstraction layer (NAL) unit header of at least one second picture following the first picture and determining a NAL unit type of the at least one second picture; removing the at least one second picture from the bitstream on the basis of the determined NAL unit type; and decoding and displaying the bitstream from which the at least one second picture has been removed.
