发明名称 Digital broadcast reproduction device and digital broadcast recording device
摘要 There is disclosed a digital broadcast recording/reproduction device capable of easily searching for an updated data broadcast. In this device, a data broadcast update recording unit (125) receives an event message and a report on a module modification from a data broadcast reproduction unit (111) and, by analyzing the contents reported, it records the updated information and the update time in a data accumulation unit (109). When a whole control unit (122) receives a rewinding request from an input control unit (121), a reproduction control unit (127) is controlled so that the reproduction control unit (127) reproduces a data broadcast from the updated portion recorded in the data accumulation unit (109).
