Description

Tele video device with reservation protection

The present invention relates to a tele video device in which a television receiver and a video device are integrally integrated. Particularly, in a tele video device having a single tuner, a reservation protection function is provided to protect a reservation recording function registered by a viewer. It is about a televideo device equipped.

In recent years, as the functions of a television receiver have been advanced and complexed, a televideo apparatus in which a television receiver and a video apparatus are integrated has been developed and spread.

Since the television part and the video part are combined through an internal circuit, such a tele video device can prevent noise caused by external noise in processing a video signal reproduced from a video tape through the television part. In addition, since several circuits can be shared, the manufacturing cost is reduced.

On the other hand, according to the above-mentioned tele-video device can be divided into one-tuner and two-tuner according to the number of the tuner provided, where the two-tuner can provide a variety of functions and convenient reservation function Since the two tuners and the image detection means must be provided, the manufacturing cost increases.

Therefore, a single tuner is usually used in the entry type televideo apparatus.

However, in the above-described single-tuner type televideo device, it is impossible to record another broadcast channel while watching a television receiver, so if a viewer turns on the televideo device during the reserved recording function, the reserved recording is performed. It is supposed to stop the function.

Therefore, a problem arises in that other viewers who are not aware of the pre-recording selection situation can not record important broadcast programs by turning on the televideo apparatus.

Accordingly, an object of the present invention is to provide a televideo device having a reservation protection function that can be used to protect a reservation recording function set by a viewer in a one-tuner type televideo device. There is this.

The operation of the device having the above-described configuration will be described below with reference to the operation flowchart shown in FIG.

When the viewer operates the remote controller 13 to input the reserved recording time and the recording channel of the tele video apparatus while the tele video apparatus is turned on, the processor 25 transmits the input reserved recording data to the data storage unit 15. After the storage, the time data by the timer 16 is compared with the time data stored in the data storage unit 15 to determine whether the reservation time has arrived (step ST1).

On the other hand, when the time data by the timer 16 and the time data stored in the data storage unit 15 are matched in step ST1, that is, when the scheduled recording time comes, the processor 25 turns on the current televideo device. It is determined whether it is in a state (step ST2).

When the televideo device is in the ON state, the tuner 2 is first tuned based on the channel data stored in the data storage unit 15 to tune the reserved channel and the OSD generation unit 17. The control is executed to guide the summary of the scheduled recording (step ST3).

In this case, the processor 25 sets the recording mode for the system controller 19, and the system controller 19 controls the video unit 18 to execute the recording operation. The audio and video signals output from the detector 6 are recorded by the video unit 18.

In this case, the audio and video signals output from the audio detector 5 and the image detector 6 are applied to the audio processor 8 and the image processor 10 through the switching unit 7. Channel broadcasting, which is currently being recorded, can be viewed through the speaker SP and the CRT.

On the other hand, when the viewer operates the remote control device 13 to perform channel switching in the recording state (step ST4), the processor 25 controls the OSD generator 17 to record the channel when the channel switching is desired. When the user outputs a guide message to release (step ST5) and the viewer views the guide message to operate the remote control device 13 to release the recording operation or when the recording time stored in the data storage unit 15 ends. (Step ST6, ST7), the system controller 19 is controlled to stop the recording operation of the video unit 18, thereby releasing the recording mode (step ST8).

On the other hand, when the current tele video device is in the OFF state in step ST2, the processor 25 internationally tunes the tuner 2 based on the channel data stored in the data storage unit 15, and the system controller. By controlling the video unit 18 through 19, the reserved recording operation is executed (step ST9).

If the viewer operates the remote control device 13 to turn on the televideo device during the recording operation (step ST10), the processor 25 first controls the relay driver 24 to control from the main power supply 21. By applying the output operation power to the flyback transformer 22, the televideo device is turned on and the OSD generator 17 is controlled to output a guide message indicating that the reserved recording is currently being executed, and then proceed to step ST4. (Step ST11).

Therefore, in this case, the viewer can watch the channel broadcast tuned by the tuner 2 through the speaker SP and the CRT.

In addition, when the recording time stored in the data storage unit 15 is terminated in the state where the tele video device is not turned on in step ST10 (step ST12), the scheduled recording is terminated as in the normal operation (step ST6). ).

Therefore, in the above embodiment, the reservation recording operation is continuously performed even when the viewer turns on the televideo apparatus while the reservation recording is executed.

In addition, if the viewer inadvertently performs channel switching in the state of executing the above-described reserved recording operation, the channel switching is performed immediately after the viewer releases the recording mode without executing the channel switching immediately. The operation is not stopped without permission.

In addition, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the technical scope of the present invention.

As described above, according to the present invention, it is possible to realize a televideo device having a reservation protection function that can protect a reservation recording function set by a viewer in a one-tuner type televideo device.
