Abstract:
1. An image transfer apparatus comprising: a generator that generates packets, each of the packets having an error detecting code which is added to image data; a scrambling device that scrambles the packets generated by the generator, on a packet-to-packet basis in order to reduce repetition of identical data; a first converter that subjects the packets obtained through the scrambling to conversion from parallel data into serial data and that transfers the packets obtained through the conversion to a target apparatus; a second converter that receives the packets which have been transferred from the target apparatus and which are obtained through the scrambling and that subjects the received packets to conversion from serial data into parallel data; a descrambling device that descrambles the packets which have been subjected to the conversion into parallel data by the second converter; a detector that detects an error on the basis of the error detecting code of each of the packets obtained through the descrambling; and a retransmission request unit that, when the detector detects the error, requests the target apparatus to retransmit the packet in which the error is detected.
