A table creating unit receives program information and an upper limit bit rate of EPG data, creates a table of EIT [current/net] on the basis of the information and upper limit bit rate, and determines the frequency of transmission of the table in consideration of the upper limit bit rate and the lower limit of the frequency of transmission of the table. A stream transmitting unit receives the table and the frequency of transmission, converts the table to stream information, and transmits a stream at a frequency determined based on the transmission frequency. Therefore, data transmission is carried out satisfying both the limit of the upper limit bit rate and the limit on the transmission frequency.
