    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: Various embodiments of the present disclosure propose an apparatus and method for supporting a service for one program through a channel change in a digital broadcasting system. To this end, a broadcast providing device may monitor whether a channel switching event occurs while providing a service for a first program on a first channel on the basis of a predetermined broadcast program schedule. When the channel switching event occurs, before the service for the first program on the first channel ends according to the predetermined broadcast program schedule, the broadcast providing device may transmit, to a broadcast consumer device, connection control information required to continue the service for the first program on a second channel. The broadcast consumer device may perform service switching on the basis of the connection control information.

    Abstract: A transmitting apparatus is provided. The transmitting apparatus includes: a baseband packet (BBP) generator configured to generate a BBP including a header and payload data; a frame generator configured to generate a frame including the BBP; a signal processor configured to signal-process the generated frame; and a transmitter configured to transmit the signal-processed frame. The header includes information about a type of the payload data, whether an additional header exists, a length of the payload data, and a Least Significant Bit (LSB) of the length of the payload data. Therefore, various types of data are mapped on a physical layer based on information included in the header, and data processing efficiency is improved.

    Abstract: A transmitting apparatus, a receiving apparatus, and a method of signal processing are provided. The transmitting apparatus includes at least one processor configured to implement: a packet generator which generates a packet including a header and a payload, based on an input stream; and a signal processor which signal-processes the generated packet. The header includes a base header, and the base header includes various fields indicating at least one of a packet type, and a value indicating that the packet transmits one single complete input packet, a segment of an input packet, or a plurality of input packets. The fields included in the base header may also indicate presence of an additional header and a substream identifier.
