A receiving apparatus identifies the type of each body-insertable apparatus and determines the mode of signal processing for a signal received from the body-insertable apparatus, and thus is capable of handling the receipt of data from a plurality of types of body-insertable apparatuses. A receiver (12) receives serial data transmitted from a body-insertable apparatus. The serial data includes a payload portion that indicates actual content of the serial data and an additional portion that is added to the payload portion and contains attribute information that varies according to each type of body-insertable apparatus. An identifying unit (19) identifies the type of the body-insertable apparatus based on the attribute information contained in the additional portion of the serial data. A processing determining unit (20) selects a mode of signal processing performed on the payload portion of the serial data by a signal processor (14) based on the identification result. Thus, one receiving apparatus can perform processing suitable for each of the signals received from different types of body-insertable apparatuses.
