Abstract
In a transmission device, an image signal and an audio signal are played back at a speed n times normal speed from a recording medium and the played back image signal is encoded. The played back audio signal is sampled using a sampling clock signal of a sampling frequency which is proportional to the speed n times normal speed. When n>1, 1/n items of sampling data of the sampling data generated by sampling is encoded. When n<1, all of the sampling data generated by sampling is encoded. The encoded image signal and encoded audio signal are then transmitted to a terminal device.
