Abstract: PURPOSE: An apparatus and a method for transmitting and receiving a packet in a broadcasting system are provided to allocate a padding size field by using padding octets, thereby increasing transmission efficiency. CONSTITUTION: A packet generation unit sets predetermined bits in a header (201) of a packet as a padding indication field (207) presenting whether the packet is padded. The packet generation unit generates the packet by allocating a padding size field (209) to the last octet of padding octets (205). A transmission unit transmits the generated packet. The padding size shows that there exists an additional padding size field in the padding octets. The padding size field is allocated variably depending on the number of the padding octets.
