Skipping can implicitly indicate that a child is locked.

(3) Processing in the Present Invention: Next, the processing relating to the child lock function in the present invention will be described in detail with reference to a flowchart. FIG. 4 is a flowchart for setting the operation in the lock area in the present invention. In this flow, it is determined whether or not an instruction to turn on the child lock function has been issued (step S100). If it is determined that the instruction to turn on the child lock function has been made, the OSD signal output unit 26 outputs a predetermined message. An OSD signal for displaying is output. The infrared signal decoding unit 21a receives an input from the remote controller 40 and receives an operation setting instruction (step S110).

Then, first, a display for inquiring whether or not the lock area setting instruction is a tape type is displayed, and the content of the instruction is determined (step S 110). When it is determined that the tape type is specified, the video deck is displayed. Then, the tape type lock is set to ON (step S120). If it is not determined in step S110 that the tape type has been instructed, a display for inquiring whether or not the lock area setting instruction is of the time type is performed, and the content of the instruction is determined (step S130).

When it is determined that the time type has been instructed, an OSD display prompting input of a time for designating a lock area is performed and the time input is received to turn on the time type lock (step S140). The VCR stores this time, and sets the time-type lock to ON so that the set operation is executed each time the time reaches this time (step S150). If it is not determined that the time type has been instructed, a display for inquiring whether or not the lock area setting instruction is of the constant type is made and the content of the instruction is determined (step S160). If it is determined in step S160 that the normal type has been released, the permanent lock is set to ON in the video deck (step S170).

After the execution type of the child lock function is set as described above, the selected operation is performed in the lock area. That is, when the tape type lock is set to ON, the flowchart shown in FIG. 5 is executed at the stage where the lock area determination unit 25 determines that the tape in which the lock area is written is loaded. . When the time type lock is set to ON, the flowchart shown in FIG. 5 is executed when the lock area determination unit 25 determines that the time set in step S140 has been reached. When the permanent lock is set to ON, the lock area determination unit 25 determines that the tape position of the lock area recorded in the memory 51 in the cassette has been reached during the reproduction of the video tape. At the stage, the flowchart shown in FIG. 5 is executed.

When the flowchart shown in FIG. 5 is executed, the lock area determination unit 25 accesses the set operation storage unit 21c to determine the set operation. When it is determined that the setting operation is to discharge the tape (step S200), a predetermined control signal is output to the discharge control circuit 10a to discharge the digital video cassette 50 (step S205). When it is determined that the setting operation is a high-speed running of the tape (step S210), a predetermined control signal is output to the reproduction control unit 23 to cause the video tape to run at a high speed. At this time, the lock area determination unit 25 grasps the number of counts at which the high-speed running should be stopped based on the lock area information obtained via the memory I / F 24, and counts the count from the counting unit 27 while running the video tape at high speed. The number of counts is acquired, and the high-speed traveling is stopped at the count number at which the high-speed traveling should be stopped (step S215). That is, the lock area is skipped by the FF operation.

When it is determined that the setting operation is the switching of the power supply state (step S 220), a predetermined control signal is output to the power supply SW 53, and the power supply is turned off, that is, set to the standby state (step S 225). . The setting operation displays an OSD display for prompting the input of a password, an OSD display indicating that the child is locked, and an OSD display of characters indicated by character information input through the remote controller 40. If it is any of the operations to be performed, it is determined whether or not there is a message to be subjected to the OSD display by these operations (step S230).

If it is determined in step S 230 that there is a message for which OSD display is to be performed, it is determined whether or not to perform an operation of displaying a character input via remote controller 40 (step S 235). When it is determined that the operation for displaying the character input through the remote controller 40 has been selected, the lock area determination unit 25 accesses the character data storage unit 21b and selects the message input in advance. You. Then, a control signal is output to the OSD signal output unit 26 to output an OSD signal for displaying the message (step S240). As a result, the pre-input message is displayed on the CRT of the television.

When it is determined in step S 235 that the operation for displaying the character input through the remote controller 40 has not been selected, the operation for displaying the OSD prompting the input of the password and the operation during child lock The parameter is set so as to perform the corresponding OSD display based on which of the operations for performing the OSD display indicating that the OSD display is selected (step S245). That is, the OSD display prompting the input of the password and the data for displaying the OSD display indicating that the child is locked are registered in advance, and the lock area determination unit 25 selects an appropriate parameter by selecting the parameter. The data is selected, and the OSD signal output section 26 outputs an appropriate OSD signal. With the above processing, the operation selected by the user in the lock area can be executed. Therefore, it is possible to implicitly or explicitly indicate that the child is being locked according to the intention of the operation setting person.

(4) Other Embodiments In the present invention, by configuring the operation in the lock area so as to be selectable, it is possible to make it difficult for the user to know that the child is locked in the child lock. If possible. In this sense, the invention is not limited to the above embodiment, and various other configurations can be adopted. For example, any one of the above-mentioned operations, not all, may be selectable, or two or more operations may be combined and executed. Further, a configuration in which the execution type of the child lock function can be selected is not essential, and only one of them may be used.

The video deck described above is a deck for reproducing the digital video cassette 50, but may be a VHS format video deck or the like. In this case, the lock area information may be recorded so as to be superimposed on the control track of the video tape or the vertical blanking period. Instead of recording on a video tape, the lock area information may be recorded on the main body of the VCR while the video cassette is uniquely identified. Furthermore, various messages can be adopted as the message to be displayed on the OSD. For example, in order to clearly indicate that the child is locked, "change the tape", "insert the tape", "change the tape" A message such as “tape” may be displayed.

As described above, according to the present invention, the operation in the lock area can be selected for the video deck in which the reproduction of the video tape is prohibited in the lock area in the normal state. In the normal state, the display for prompting the user to input the password for releasing the lock area is not performed. Therefore, it is possible to make it difficult for the user to make clear that the child is locked, depending on the desired selection.
