Storing apparatus

A storing apparatus comprising:

• a storing/reproducing module which stores and reproduces program streams and program names in a recording medium;
• a communication module which transmits and receives each program stream stored in the recording medium to and from a server connected to a network;
• a compression module which compresses each program stream stored in the recording medium to have a size smaller than a current size;
• a priority setting module which automatically sets a priority of deleting each program stream stored in the recording medium according to a predetermined condition;
• an instruction module which instructs reproducing each program stream stored in the recording medium;
• and
• a control module which controls the storing/reproducing module, the communication module, and the compression module,
• wherein, when a free capacity of the recording medium is small, the control module controls the compression module to compress each program stream stored in the recording medium to have the size smaller than the current size or controls the communication module to transmit the program stream to the server, according to the priority set by the priority setting module, deletes the program stream stored in the recording medium, and leaves the program name corresponding to the deleted program stream, and
• when an instruction reproducing the program stream corresponding to the left program name is received, the control module controls the storing/reproducing module to reproduce the corresponding compressed program stream or controls the communication module to receive the corresponding program stream from the server to reproduce the received program stream.
