Abstract
In a system for receiving and storing broadcast content data, a reception and storage device receives and stores a portion of broadcast content data in a storage unit, and then generates and stores a first piece of error check data for the data portion. The reception and storage device receives, from a further device, a second piece of error check data for a portion of the broadcast content data corresponding to the data portion stored in the storage unit, compares the first piece of error check data with the second piece of error check data to determine whether the first piece of error check data is valid, receives, if the first piece of error check data is determined to be invalid, the corresponding data portion associated with the second piece of error check data, from another reception and storage device, and corrects the stored data portion in the storage unit based on the received corresponding data portion.
