PROBLEM TO BE SOLVED: To provide a transmitter capable of efficiently transmitting variable-length packets such as IP packets while transmitting a TS of a digital broadcasting, and a receiver therefor.SOLUTION: A transmitter 10 includes: a variable-length packet division section 11 which divides a variable-length packet and allocates the resultant packet to a TS-like packet having the same packet length as a TS packet; a multiple frame header generation section 13 which generates multiple frame header information including array position information on the TS packet and TS-like packet and head position information for representing the head position of the variable-length packet; a multiplexing section 12 which multiplexes the TS packet, the TS-like packet, and the multiple frame header information in a plurality of predetermined TS multiple frames; and a transmission section 14 which transmits the multiplexed signal to the outside. A receiver 20 receives the multiplexed signal and extracts the TS-like packet from the plurality of TS multiple frames to restore the variable-length packet. |
