Abstract: A receiving apparatus includes a receiver, a signal processor, an identifying unit, and a processing determining unit. The receiver receives serial data transmitted from a body-insertable apparatus, the serial data including a payload portion that indicates actual content of the serial data and an additional portion that is added to the payload portion as a signal indicating a position to start processing and contains attribute information that varies according to each type of body-insertable apparatus. The signal processor performs predetermined signal processing on the payload portion of the serial data. The identifying unit identifies a type of the body-insertable apparatus based on the attribute information contained in the additional portion of the serial data. The processing determining unit selects a mode of signal processing performed on the payload portion by the signal processor based on an identification result obtained by the identifying unit.
