Abstract: A transmitting apparatus, a receiving apparatus and methods of controlling these apparatuses are provided. The transmitting apparatus includes: a baseband packet generator configured to, based on an input stream including a first type stream and a second type stream, generate a baseband packet including a header and payload data corresponding to the first type stream; a frame generator configured to generate a frame including the baseband packet; a signal processor configured to perform signal-processing on the generated frame; and a transmitter configured to transmit the signal-processed frame, wherein the header includes a type of the payload data in the baseband packet and the number of the first type stream packets in the baseband packet.

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 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.

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.
