The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which an increase in data size of signaling information transmitted by broadcasting can be suppressed. Provided is a reception apparatus including: a reception unit that receives a broadcast wave of digital broadcasting using an IP (Internet Protocol) transmission system; and a control unit that controls, on the basis of information for managing only a broadcast component transmitted by a broadcast wave of the digital broadcasting, which is first signaling information transmitted by a broadcast wave of the digital broadcasting, or information for managing at least one component of the broadcast component and a communication component transmitted by communication, which is second signaling information transmitted by communication, operations of respective units for acquiring the at least one component of the broadcast component and the communication component. The present technology is applicable to a television receiver, for example.

A decoding circuit applied to a multimedia apparatus is provided. The decoding circuit is for decoding encoded data to generate system information, and includes multiple processing circuits and a determination circuit. The multiple processing circuits individually process the encoded data to generate multiple processed signals, and respectively correspond to multiple bit combinations of a part of the system information. The determination circuit determines the system information according to the multiple processed signals.
