Abstract: The present technique relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method which make it possible to control redundancy of a header in packet communication. A region representing a packet length in a header of a packet is switched and set according to a size of a payload of an input packet. That is, according to the packet length, switching between a short packet mode to represent the packet length only by five bits of a packet length part FH1-3 in a minimum fixed length header FH1, a variable length mode to represent the packet length by 11 bits of the packet length part FH1-3 and a packet length part VH1-1 in a variable length header VH1, and an additional variable length mode to represent the packet length by 16 bits of the packet length part FH1-3, the packet length part VH1-1, and a packet length part AH1-2 in an additional header AH1 is performed. The present technique can be applied to broadcast communication.
