1. A playback apparatus that can communicate with a second server, which temporarily stores in a first buffer compressed digital data that is received from a first server, and when the first buffer has stored a first data volume of the compressed digital data, which is a volume that is sufficient for a decoding of the compressed digital data, reads the compressed digital data out of the first buffer and decodes it into decompressed digital data, the playback apparatus comprising:

  • a communication portion that transmits data to and receives data from the second server;

    a second buffer that temporarily stores the decompressed digital data that is received from the second server through the communication portion;

    a D/A conversion portion that performs a D/A conversion of the decompressed digital data, which is read out from the second buffer, and outputs analog data;

    a control portion that performs control such that, when a second data volume of the decompressed digital data, which is a volume that is sufficient for the D/A conversion portion to operate without an interruption of its output, has been temporarily stored in the second buffer, the decompressed digital data that is temporarily stored in the second buffer is transferred to the D/A conversion portion; and

    a notification information generation portion that generates notification information that conveys storage statuses of the first buffer and the second buffer.
