RE-MULTIPLEXING APPARATUS, BROADCASTING SYSTEM, RE-MULTIPLEXING METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING PROGRAM

A re-multiplexing apparatus, a broadcasting system, a re-multiplexing method, and a program capable of, when broadcast data having a first resolution and broadcast data having a second resolution are broadcasted, synchronizing their outputs with each other are provided. A re-multiplexing apparatus includes a first re-multiplexing unit and a second re-multiplexing unit. The second re-multiplexing unit inserts a delay control packet at a timing corresponding to a timing of a first packet of an OFDM frame, the delay control packet being a packet containing control information for compensating for a difference between delay times of the first and second lines. When doing so, the second re-multiplexing unit generates, as the control information, an index value of a waiting time from a time when the delay control packet is received in a transmitting apparatus to a start of a modulation process for a packet following the delay control packet.
