Abstract
In an information transmission method and apparatus, information is transmitted in units of a block including information codes and error-correcting check codes, and the transmission speed is switched by changing the number of blocks to be transmitted per unit time without changing the amount of information of the information codes and the amount of information of the error-correcting check codes within each block.
