Abstract: [Object] To provide a transmission apparatus, a reception apparatus, a frame rate conversion system, and a frame rate conversion method that are capable of transmitting reference control information even when a data amount of the reference control information is large. [Solving Means] In a reproducing apparatus (151), a decode unit (152) decodes a certain amount of encoded video data. The decoded video data and reference control information (motion vector and identifier described above) obtained at a time of the decode are supplied to a transmission interface (153), and the transmission interface (153) transmits them to a display apparatus (161). The transmission interface (153) includes a first transmission channel for transmitting the decoded video data and a second transmission channel for transmitting the reference control information.
