Abstract
A data receiving apparatus has a unidirectional channel receiver for receiving segmental data forming an electronic file, through a unidirectional channel; a file assembler for restoring the electronic file, based on the segmental data received by the unidirectional channel receiver; a channel information memory for acquiring location information for specifying a location of the electronic file; and a bidirectional channel transmitter/receiver for establishing a bidirectional channel when there arises a need for retransmission of the electronic file, for sending a request for transmission of the electronic file to a data transmitting device specified by the location information, through the bidirectional channel, and for receiving the electronic file through the bidirectional channel.
