a first demodulator operable to demodulate received scrambled data using information including a designated frequency, and to output the demodulated scrambled data;

a descrambler operable to descramble the scrambled data demodulated by said first demodulator, and to output an MPEG-2 transport stream;

a retriever operable to retrieve, from the MPEG-2 transport stream outputted by said descrambler, AV data and a file system which makes up an application;

an executioner operable to execute the application made up by the file system;

a recording controller operable to receive a record request from the executed application, and to control recording according to the received record request;

a recorder operable to record the retrieved AV data according to an instruction from said recording controller;

a holder operable to hold management information for managing the recorded data; and

a detector operable to detect a problem which occurs in processing performed from after the demodulating of the scrambled data by said first demodulator until the retrieving of the AV data,

wherein, in the case where said detector detects the problem during recording of data by said recorder, said recording controller is operable to write, into the management information, the detected problem and a time at which the problem occurred.
