Abstract
A stored type digital broadcasting receiver includes a channel decoding unit (43r) that detects apart of broadcasting contents which cannot be received correctly because of an transmission path error from the received broadcasting contents based on results of Viterbi decoding or error correction processing. When the channel decoding unit (43r) detects a transmission path error which cannot be corrected, the stored type digital broadcasting receiver makes a request of a broadcast service provider for the transmission of a complement to the received broadcasting contents. When receiving the requested complement to the broadcasting contents from the broadcast service provider, the stored type digital broadcasting receiver refers to identification information (d13) of an FEC frame (d10) included in the complement to the broadcasting contents and writes the complement to the broadcasting contents over a corresponding file stored in a storage medium of a received bitstream storing and reproducing unit (30rd), or creates a new file and stores the complement to the broadcasting contents in the new file.
