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: 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.
