Content data reproducing apparatus with temporary data memory

A method of controlling a content data reproducing apparatus having a temporary memory for stream reproduction, the method comprising the steps of:

• acquiring content data from an external content provision server;
• temporarily storing the acquired content data in the temporary memory such that the stored content data should be erased from the temporary memory when the content data reproducing apparatus is turned off;
• acquiring reproduction condition data which defines a reproduction condition for reproducing the content data;
• determining whether the content data reproducing apparatus satisfies the reproduction condition each time the content data is to be reproduced;
• reproducing the content data read from the temporary memory in case that the reproduction condition is satisfied;
• and
• erasing the content data from the temporary memory even before the content data reproducing apparatus is turned off in case that the reproduction condition is no more satisfied.

A machine readable medium for use in a content data reproducing apparatus having a processor and a temporary memory for stream reproduction, the medium containing a program executable by the processor for causing the content data reproducing apparatus to perform a method comprising the steps of:

• acquiring content data from an external content provision server;
• temporarily storing the acquired content data in the temporary memory such that the stored content data should be erased from the temporary memory when the content data reproducing apparatus is turned off;
• acquiring reproduction condition data which defines a reproduction condition for reproducing the content data;
• determining whether the content data reproducing apparatus satisfies the reproduction condition each time the content data is to be reproduced;
• reproducing the content data read from the temporary memory in case that the reproduction condition is satisfied;
• and
• erasing the content data from the temporary memory even before the content data reproducing apparatus is turned off in case that the reproduction condition is no more satisfied.
