Reception apparatus and method for controlling reception apparatus

Abstract

A reception apparatus that decodes a preamble reduces the size of a buffer that holds a decoding result. A holding unit holds a plurality of bits to each of which physical layer pipe identification information is assigned as a physical layer pipe presence/absence bit string. A reception unit receives a predetermined number of physical layer pipes that do not exceed the number of bits of the physical layer pipe presence/absence bit string and the physical layer pipe identification information of each of the predetermined number of physical layer pipes. A setting unit sets the value of the bit corresponding to the received physical layer pipe identification information of the physical layer pipe presence/absence bit string to one of two values, and sets the value of a non-corresponding bit to another of the two values. A decoding processing unit performs processing for decoding the physical layer pipe corresponding to the bit of the one value.
