    Abstract: A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.

    Abstract: An apparatus and a method for transmitting uplink information in a broadcasting system are provided. A repeater of a mobile broadcasting system includes a plurality of transmitting stations each transmitting a broadcast signal for at least one broadcast service, a plurality of terminals receiving the broadcast signal for the at least one broadcast service through at least one transmitting station among the transmitting stations, and the repeater, the repeated being coupled between the plurality of transmitting stations and the plurality of terminals. The repeater includes a receiving unit configured to receive uplink information from the terminals, a control unit configured to classify the received uplink information by broadcast service and to create uplink information per broadcast service, and a transmitting unit configured to transmit the created uplink information to at least one corresponding transmitting station.

    Abstract: The present invention relates to a method and device for transmitting or receiving a broadcast service including a packet, which is generated using an application layer forward error correction (AL-FEC) scheme, in a multimedia service system. An embodiment of the present invention provides a method for transmitting a broadcast service by a transmitter, the method comprising the steps of: determining one forward error correction (FEC) scheme for a broadcast service among multiple FEC schemes; configuring a signaling message so as to include an identifier indicating the determined FEC scheme; and transmitting the configured signaling message.
