Abstract:
1. A transmitting/receiving apparatus for packetizing input continuous data and transmitting the packetized data to another apparatus on a communication network, and receiving a packet transmitted from another apparatus, comprising: a packet construction section for dividing the continuous data into a plurality of subpackets, and constructing a packet by concatenating the plurality of subpackets; a modulation transmission section for modulating the packet constructed by the packet construction section, and transmitting the modulated packet to another apparatus on the communication network; a training session execution section for checking channel conditions, when a predetermined condition is satisfied, by communicating with another apparatus, and changing a modulation rule used in the modulation transmission section so that a packet transmitted from the modulation transmission section is successfully transmitted to a transmission destination apparatus; a subpacket transmission confirmation section for confirming whether or not a subpacket included in the transmitted packet is transmitted successfully to the transmission destination apparatus; and a postbuffer for storing data transmitted from another apparatus, wherein if the modulation rule is changed by the training session execution section: the data stored in the postbuffer is not readable if an amount of the data stored is smaller or equal to a predetermined threshold value, and is readable if the amount of the data stored exceeds the predetermined threshold value, and the data stored in the postbuffer is read, irrespective of the amount of the data stored, during an execution of a training session which is performed by the training session execution section for changing a modulation rule used in the modulation transmission section.
