DATA TRANSMISSION DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To efficiently transmit image data from a computer to a display device. SOLUTION: A scheduler 344 discriminates whether or not increase in a data quantity caused by revision in an image drawing instruction can be cancelled through merging and changes the image drawing instruction when the increase can be cancelled. A communication controller 40 generates a transmission packet including the merged image drawing instruction by a prescribed data amount or over and transmits the packet to the display device.
