  • Description: To provide a demodulation module with high versatility.SOLUTION: A demodulation module 300 performing demodulation processing of a broadcast signal of a digital broadcast, and outputting a TS signal of one system or two systems, comprises: a first output terminal group G31 and a second output terminal group G32; a first demodulation part 310 that performs the demodulation processing of a first IF signal i31 and outputs a first TS signal t31 based on the demodulation processing; a second demodulation part 320 that performs the demodulation processing of a second IF signal i32 and outputs a second TS signal t32 based on the demodulation processing; a first signal shaping part 330 that shapes the first TS signal t31 to output a first shaping TS signal f31 having a predetermined output form; a second signal shaping part 340 that shapes the second TS signal t32 to output a second shaping TS signal f32 having the predetermined output form; and an output selection part 350 that distributes the first shaping TS signal f31 and the second shaping TS signal f32 to the first output terminal group G31 and the second output terminal group G32 to be output.SELECTED DRAWING: Figure 16 【課題】汎用性の高い復調モジュールを提供する。【解決手段】デジタル放送の放送信号を復調処理し、１系統または２系統のＴＳ信号を出力する復調モジュール３００であって、第１出力端子群Ｇ３１および第２出力端子群Ｇ３２と、第１のＩＦ信号ｉ３１を復調処理して、復調処理に基づく第１のＴＳ信号ｔ３１を出力する第１復調部３１０と、第２のＩＦ信号ｉ３２を復調処理して、復調処理に基づく第２のＴＳ信号ｔ３２を出力する第２復調部３２０と、第１のＴＳ信号ｔ３１を整形して所定の出力形式を有する第１の整形ＴＳ信号ｆ３１を出力する第１信号整形部３３０と、第２のＴＳ信号ｔ３２を整形して所定の出力形式を有する第２の整形ＴＳ信号ｆ３２を出力する第２信号整形部３４０と、第１の整形ＴＳ信号ｆ３１および第２の整形ＴＳ信号ｆ３２を第１出力端子群Ｇ３１および第２出力端子群Ｇ３２へ振り分けて出力する出力選択部３５０と、を備える。【選択図】図１６
