ABSTRACT:
An object of the invention is to provide a transmitting system of which data is difficult to be tapped and which is suitable for flexibly determining a watching and listening fee. In order to achieve the object, there is provided a combination of a transmitting method comprising steps of, transmitting encoded data which has been encoded, to a receiving side, changing the encoding in a predetermined unit, and performing recording according to requirement, from the receiving side of information concerning decoding of the encoded data, and a receiving method comprising steps of, receiving the encoded data which has been encoded, from a transmitting side, requiring the information concerning the decoding of the encoded data, to the transmitting side, and decoding the encoded data by using the obtained information concerning the decoding.
