摘要

Provided is a transmitting apparatus, a receiving apparatus, and the like that can switch a content even if the reception conditions of a plurality of streams are deteriorated at the same time, and that have reduced power consumption and an increased packet loss tolerance. The receiving apparatus includes: a first reception section for receiving a first stream by predetermined unit and extracting first content data; a control section for determining whether or not the first stream has been normally received, with respect to each predetermined unit, and for, if the first stream has not been normally received, issuing an instruction to start reception of a second stream to be transmitted later than the first stream; a second reception section for, when the second reception section has received the instruction, starting reception of the second stream, receiving the second stream corresponding to the predetermined unit of the first stream that has not been received, and extracting second content data; and a reproduction control section for, if the first stream has not been received, reproducing a content for alternative display based on the second content data, and for, if the first stream has been received, reproducing a content for normal display based on the first content data at the same timing as a timing to reproduce the content for alternative display.
