The program transmission apparatus 1 includes a transmission processing section 11. The program reception terminal 3 includes a reception-side storage section 34 and a discard processing section 32. The transmission processing section 11 transmits a program and discarding procedure information to the program reception terminal 3. The discarding procedure information relates to a procedure of discarding the program performed by the program reception terminal 3. The reception-side storage section 34 stores the program transmitted from the transmission processing section 11. The discard processing section 32 discards the program stored in the reception-side storage section 34 according to a discarding procedure specified by the discarding procedure information transmitted from the transmission processing section 11.
