Recording and reproduction apparatus and recording and reproduction method

A recording and reproduction apparatus which receives and records a content included in a broadcast wave, and executes an application program included in a predetermined service in parallel with reproduction of the recorded content, said recording and reproduction apparatus comprising:

• a storage in which the received content and the application program are stored;
• an executor operable to execute the application program;
• a reproducer operable to reproduce the content stored in said storage;
• and
• a reproduction speed controller operable to receive a reproduction speed of the content requested by the application program, and to control a reproduction speed of the content to be reproduced by said reproducer so as to be in the received reproduction speed,
• wherein, in the case where a first application program which has requested the reproduction speed of the content already accepted as a speed other than a normal reproduction speed and a second application program which requests a new reproduction speed to said reproduction speed controller are different, when said reproduction speed controller receives the new reproduction speed request, said reproduction speed controller is operable to:
• determine whether or not the first application program and the second application program belong to different services by comparing information relating to an identifier of a service to which the first application program belongs with information relating to an identifier of a service to which the second application program belongs;
• and
• refuse a reproduction speed change request from the second application program, in the case where the second application program does not belong to the service to which the first application program belongs.
