A reception apparatus includes processing circuitry that receives a predetermined number of audio streams including coded data of a plurality of groups and configuration information of the predetermined number of audio streams. The processing circuitry controls display of a user interface that includes selection information for at least one group from among the plurality of groups based on the configuration information. The processing circuitry receives a user selection operation of a group of the at least one group to be decoded. The processing circuitry fetches audio streams including the group from the predetermined number of audio streams and obtains one audio stream constructed by integrating the fetched audio streams. Further, the processing circuitry inserts a command to selectively decode the coded data of the group from among the predetermined number of groups included in the one audio stream into the one audio stream.
