BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a DVD recorder 11 described in this embodiment. That is, the DVD recorder 11 includes an AV input unit 12 for externally inputting video and audio data, and a TV (Television) tuner 13 for selecting a predetermined channel from a received television broadcast signal. I have.
[0013]
The AV input unit 12 and the TV tuner 13 output the acquired video and audio data to the encoder unit 14. The encoder unit 14 performs predetermined compression coding processing, modulation processing, error correction code addition processing, and the like on the input video and audio data, and converts the data into a format suitable for recording. It is output to the unit 15.
[0014]
The disk drive unit 15 temporarily records the video and audio data input from the encoder unit 14 on a hard disk by using an HDD (Hard Disk Drive) 16. Thereafter, the disk drive unit 15 reads out video and audio data recorded on the hard disk via the HDD 16 and outputs the data to the disk drive 17.
[0015]
The disc drive 17 can selectively mount an optical disc 18 such as a DVD-RAM and a DVD-R. The disk drive 17 drives the mounted optical disk 18 to rotate, and records the video and audio data input from the HDD 16 on the optical disk 18 using the temporary recording unit 19 as a buffer by an optical head.
[0016]
The disk drive unit 15 outputs video and audio data read from the optical disk 18 by the disk drive 17 using an optical head to the decoder unit 20. The decoder unit 20 performs a decoding process, a demodulation process, an error correction process, and the like on the input video and audio data, and then outputs the data to an AV output unit 21 for deriving the data outside the DVD player 11. ing.
[0017]
An MPU (Micro Processing Unit) 22 controls the recording / reproducing operation on the optical disk 18 as described above. The MPU 21 reflects operation information of the operation input unit 26 input via the timer MPU 25 based on control software stored in the memory 23, firmware stored in a flash ROM (Read Only Memory) 24, and the like. Each part is controlled.
[0018]
The memory 23 provides a work area to the MPU 22 and records various setting data such as recording reservation information. The timer MPU 24 performs a time measurement operation for realizing a recording operation based on the recording reservation information recorded in the memory 23, and generates information for instructing the MPU 22 to start or stop recording. I have. Further, the MPU 22 displays a current operation state, various setting states, and the like on the display unit 27.
[0019]
Here, the MPU 22 is connected to the communication control unit 28. The communication control unit 28 is connectable to an external network 29 such as the Internet, for example, and transmits data and commands generated by the MPU 22 to the network 29, and data and commands transmitted to the network 29. It has a function of receiving a command and supplying it to the MPU 22. The network 29 connects the PC 30. The PC 30 is owned by the user of the DVD recorder 11, for example.
[0020]
FIG. 2 shows a flowchart summarizing the operation of displaying the status information of the DVD recorder 11. The display operation of the status information is started (step S1) by the PC 30 transmitting information for requesting the acquisition of the status information to the network 29.
[0021]
The information requesting the acquisition of the status information is received by the MPU 22 via the communication control unit 28 in step S2. Then, the MPU 22 transmits a program (for example, Java (registered trademark)) for the PC 30 to acquire and display the status information on the network 29 via the communication control unit 28 in Step S3.
[0022]
As a result, the PC 30 acquires the program from the network 29 and transmits, on the network 29, information requesting connection to the DVD recorder 11 based on the program.
[0023]
Therefore, in step S4, the MPU 22 inputs the connection request information transmitted from the PC 30 to the network 29 via the communication control unit 28, and in step S5, accepts the connection. For transmission to the PC 30, the data is transmitted to the network 29 via the communication control unit 28.
[0024]
Thereby, the PC 30 acquires and displays the status information from the network 29 in step S7.
[0025]
After that, the MPU 22 transmits the changed status information to the PC 29 via the communication control unit 28 in step S8. Then, in step S9, the PC 30 acquires the changed status information from the network 29, updates the display of the changed portion, and ends the process (step S10).
[0026]
According to the above-described embodiment, when the PC 30 requests display of status information via the network 29, the DVD recorder 11 transmits a program for displaying status information to the PC 30. The PC 30 acquires status information from the DVD recorder 11 based on the program and displays the status information.
[0027]
For this reason, within the range of the network 29, even if the DVD recorder 11 and the PC 30 are far apart, it is possible to easily request the status information display and display the status information.
[0028]
Here, as the status information, all kinds of internal information such as the reproduction time of the currently mounted optical disk 18, the type of the currently mounted optical disk 18, the currently selected broadcast channel, and the like can be set.
[0029]
Further, the network 29 is not limited to the Internet, and various communication networks such as a LAN (Local Area Network) can be widely used.
