Disclosed is a tuner device including an input terminal, a separator, a first amplifier, a second amplifier, and a tuner. The input terminal receives an input of a reception signal of satellite digital broadcasts. The separator is connected to the input terminal and adapted to frequency-separate a first signal and a second signal. The first signal is in a low-frequency domain of the reception signal, and the second signal is in a high-frequency domain of the reception signal. The first and second amplifiers respectively amplify the first and second signals. The tuner receives an input of output signals from the first and second amplifiers.

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.
