1. A broadcasting receiving apparatus, comprising:

  • a tuner configured to output a reception signal on a specific channel selected from a broadcasting signal;

    a demodulation portion configured to output a video audio signal by demodulating the reception signal outputted from the tuner;

    an encryption portion configured to output an encrypted video audio signal by encrypting the video audio signal outputted from the demodulation portion;

    a buffer configured to store one of the video audio signal outputted from the demodulation portion and the encrypted video audio signal outputted from the encryption portion; and

    a control portion configured to determine that, when the video audio signal from the demodulation portion needs to be encrypted in the encryption portion, the video audio signal is transferred in a form of first files, each having a first capacity, encrypted on a file-by-file basis in the encryption portion, and stored into a memory region in the buffer portion successively in units of the first capacity, and that when the video audio signal from the demodulation portion need not be encrypted in the encryption portion, the video audio signal is transferred in a form of plural second files, each having a second capacity smaller than the first capacity on the file-by-file basis, and stored into the memory region in the buffer portion successively in units of the second capacity.
