Patent ID: 7233734

Claim:
An audio visual data recording/reproducing apparatus configured to be connected with an external equipment via a bus, comprising: a digital input/output (I/O) interface for receiving and outputting an audio visual stream via the bus; a recording control section for producing audio visual data including audio visual information and management information from the audio visual stream received through the digital I/O interface; a hard disk drive for storing the audio visual data produced by the recording control section; a recording/reproduction control program stored in a region of the hard disk drive other than that for storing the audio visual data, the recording/reproduction control program to be read from the hard disk drive and to be executed; a reproduction control section for reproducing the audio visual stream based on the audio visual data read from the hard disk drive, and outputting the reproduced audio visual stream via the digital I/O interface; and a microcomputer having a non-volatile memory; and a connection confirmation/processing program stored in the non-volatile memory, the connection confirmation/processing program to be executed during starting time of the hard disk drive after power-on, wherein the microcomputer executes the connection confirmation/processing program stored in the non-volatile memory during starting time of the hard disk drive after power-on in order to confirm connection with the external equipment via the digital I/O interface and to execute processing required for the connection, and then executes the recording/reproduction control program read from the hard disk drive in order to determine respective operation modes of the recording control section and the reproduction control section.
