摘要： 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, 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.

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.
