To provide a recorder that can change its video recording modes automatically according to the type of a signal received without having the user pay his or her attention to the signal type even in a situation where HD and SD video signals having mutually different transfer rates are broadcast on the same channel. The recorder can write a data stream on multiple types of storage media and includes: a receiving section for receiving a digital broadcasting wave and outputting a data stream; a transfer rate detecting section, which receives the data stream and detects its transfer rate; a recording processing section for performing either a first type of recording processing including a compression coding process or a second type of recording processing including no compression coding process on the data stream received; and a selecting section for selecting either the first or second type of recording processing according to the transfer rate. The recorder writes the data stream that has been processed by the recording processing section on one of the storage media.
