Patent ID: 7050202

Claim:
An image data transmission method of transmitting a plurality of groups of image data, which image data has an image format in which an amount of data changes with only an amount of change in the image, the method comprising the steps of: determining whether or not a total volume of image data from said plurality of groups of image data that is transmitted through a frequency band at the same transmission timing exceeds a maximum volume that can be transmitted in the frequency band when transmitting image data from a transmitter for transmitting image data or a relay apparatus for relaying image data using common wiring or frequency band having the same transmission wave; and when the total volume from said plurality of groups of image data exceeds the maximum volume, temporally and selectively shifting either forwards or backwards the transmission timing of at least one group of the plurality of groups of image data from among the image data to be transmitted at the same transmission timing within a time span which is undetectable by the human eyes.
