A transmitting apparatus is provided. The transmitting apparatus includes: 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, wherein the header comprises a base header which comprises: a first field indicating a packet type of the input stream; and a second field which is set to a first value representing that the packet transmits one single complete input packet or a second value representing that the packet transmits a segment of an input packet or a plurality of input packets, wherein, when the second field is set to the first value, the base header comprises a third field which is set to a third value indicating that an additional header is not present or a fourth value indicating that the additional header is present, wherein, when the third field is set to the fourth value, the additional header comprises a fourth field indicating whether a substream identifier is present in an optional header, and wherein, when the fourth field is set to a value indicating that the substream identifier is present in the optional header, the optional header comprises a fifth field indicating the substream identifier.The present invention is designed to provide a transmitting apparatus and a receiving apparatus which generate, transmit and/or receive a frame having a format suitable for transmitting/receiving various types of data and a control method thereof. Further, since an input stream can be efficiently mapped to a physical layer, data processing efficiency can be improved. |
