[Industrial applications]

 The present invention relates to a television device. More specifically, the present invention relates to a television device (hereinafter referred to as TVCR) in which a television receiver (hereinafter referred to as TV) unit and a video cassette recorder (hereinafter referred to as VCR) unit are combined.

[0002]

[Problems to be solved by conventional techniques and devices]

 An example of a conventional TVCR is shown in FIG. As shown in FIG. 2, the conventional TVR is divided into a VCR part and a TV part. The VCR part includes a remote control receiver 101, a key matrix 102, a timer microcomputer 103, a servo / system controller (hereinafter, servo / system controller). System controller 104, deck 105, tuner 106, external terminal group 107, video signal switch 108, audio signal switch 109, video signal recording / playback unit 110, audio signal recording / playback unit 111, and VCR power supply unit 112, The TV unit includes a video signal processing unit 113, an audio signal processing unit 114, and a TV power supply unit 115.

Among the components of the VCR unit, the remote control receiving unit 101, the key matrix 102, the timer microcomputer 103, the tuner 106, the external terminal group 107, the video signal switch 108, and the audio signal switch 109 have not only the VCR function but also the TV function. It is economical because some components necessary for the normal operation of the TV section can be saved by also being involved in this.

That is, when a user transmits an instruction to watch a specific TV broadcast to the timer microcomputer 103 through the remote control receiver 101 or the key matrix 102, the timer microcomputer 103 controls the tuner 106 to send the specific TV broadcast. The video signal switch 108 and the audio signal switch 109 are controlled through the servo / system controller 104 so as to receive the video signal and the audio signal included in the specific TV broadcast, respectively. The video signal recording / reproducing unit 111 is transmitted to the video signal recording / reproducing unit 111, and the video signal recording / reproducing unit 110 and the audio signal recording / reproducing unit 111 are controlled through the servo / syscon 104 so that the video signal and the audio signal are transmitted to the video signal processing unit 113 and It is transmitted to the audio signal processing unit 114. By controlling the video signal processing unit 113 and the audio signal processing unit 114, the video and audio information including the video signal and the audio signal are displayed and reproduced through the attached replace clean and speaker. .

Similarly, when the user tries to watch a movie transmitted from the external terminal group, for example, the timer microcomputer 103 operates the video signal switch 108 and the audio signal switch 109 through the servo / system controller 104. The video signal and the audio signal from the external terminal group are controlled to be transmitted to the video signal recording / reproducing section 110 and the audio signal recording / reproducing section 111 respectively, and the video signal recording / reproducing section 110 and the audio signal recording / reproducing section 110 are transmitted through the servo / syscon 104. The audio signal recording / reproducing unit 110 is controlled so that the video signal and the audio signal are transmitted to the video signal processing unit 113 and the audio signal processing unit 114, respectively. Control through the display screen and speaker with the above video and audio. So that it will be screened.

However, in such a conventional TVCR, the function on the TV side is seriously affected by the failure of the VCR component that is not directly related to the TV unit.

For example, if the VCR power supply unit 112 fails, all the components of the VCR unit stop operating, so that no signal is transmitted to the video processing unit 113 and the audio processing unit 114. If the servo / system controller 104 fails, the video switch 108, the audio switch 109, the video signal recording / reproducing unit 110, and the audio signal recording / reproducing unit 111 are not properly controlled, and the operation of the TV unit becomes unstable. Further, if a problem occurs in the video signal recording / reproducing unit 110 and / or the audio signal recording / reproducing unit 111 transmitting the video signal and / or the audio signal to the video signal processing unit 113 and the audio signal processing unit 114. The video information and the audio information included in the video signal and the audio signal are not properly displayed or reproduced.

Therefore, a main object of the present invention is to provide an improved TVCR in which the operation of the TV unit of the TVCR is not affected by the failure of the VCR unit.

【Example】

 The above and other objects of the present invention will become apparent from the detailed description of the embodiments described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a novel TVCR according to the present invention. As shown in FIG. 1, the TVCR is divided into a VCR section and a TV section.

The VCR unit is a servo / system that performs overall control of the VCR unit in response to a mode selection signal indicating a desired operation mode of the VCR unit (for example, recording, reproduction, etc.) from the timer microcomputer 203 of the TV unit. A controller (hereinafter referred to as "servo / syscon") 204, a deck 205 controlled by the servo / syscon 204 to drive the loaded video tape in the desired mode, and a deck controlled by the servo / syscon 204 A video signal recording / reproducing unit 210, which is means for recording the video signal output from the video switch 208 of the TV unit on the video tape or reproducing the recorded video signal from the loaded video tape, and the servo / system controller 204. Output from the audio switch 209 of the TV unit on the video tape loaded under the control of A voice signal recording / reproducing unit 211 which is a means for recording a voice signal or reproducing a recorded voice signal from a loaded video tape, and a VCR power source for receiving the AC power required to drive the VCR unit. The part 212 is included.

The TV unit controls the general operation of the TV unit according to a remote control receiving unit 201, a key matrix 202, and a user's command received through the remote control receiving unit 201 and the key matrix 202. Then, the mode selection signal indicating the desired VCR operation mode is transmitted to the servo / syscon 204, and information regarding the current operation state of the VCR unit (for example, failure of VCR) is received from the servo / syscon 204. A timer microcomputer 203 that appropriately responds to the current operating state, a tuner 206 that receives a TV broadcast signal in response to a channel selection signal from the timer microcomputer 203, an external terminal group 207, a tuner 206 that responds to the channel selection signal, Selects video signals from external video input terminal 207 and video signal recording / playback unit 210 A video signal switch 208 for outputting, an audio signal switch 209 for selectively outputting an audio signal from the tuner 206, the external audio input terminal 207 and the audio signal recording / playback unit 211 according to a channel selection signal, and a timer microcomputer. Under the control of 203, a video signal processing unit 213 which processes the video signal from the video signal switch 208 and displays the video information included in the video signal on the attached display screen, and the audio under the control of the timer microcomputer 203. An audio signal processing unit 214 that processes the audio signal from the signal switch 209 and reproduces the audio information included in the audio signal through the attached speaker, and a TV power supply unit that receives the AC power necessary to drive the TV unit. 215 and the VCR power supply unit 212 according to the power supply signal from the timer microcomputer 203. Optionally including a VCR power switch 216 supplies an AC power. With such a TVCR, the operation of the TV section can be prevented even if the VCR section fails.

Hereinafter, the operation of the TVCR of the present invention will be described in more detail.

First, assuming that the VCR unit operates without failure, if the user inputs a command to operate the built-in VCR unit, for example, in the playback mode, through the remote control receiver 201 or the key matrix 202, The timer microcomputer 203 transmits data representing a desired VCR operation mode, that is, a reproduction mode, to the servo / system controller 204. The servo / system controller 204 controls the deck 205 to operate in the playback mode, and controls the video signal recording / playback unit 210 and the audio signal recording / playback unit 211 to output the video signal and audio from the loaded video tape. Try to play the signal. At the same time, the timer microcomputer 203 controls the video signal switch 208 and the audio signal switch 209 to provide the reproduced video signal and audio signal to the video signal processing unit 213 and the audio signal processing unit 214, respectively. The video and audio information contained in the signal and audio signals will be displayed on the attached display screen and played through the speakers.

On the other hand, when the user inputs a command to record a TV broadcast signal (or a signal from an external terminal), the timer microcomputer 203 indicates to the servo / system controller 204 a desired operation mode, that is, a recording mode. Transmit data. The servo / cisco 204 controls the deck 205 to operate in the recording mode, controls the video signal recording / reproducing unit 210 and the audio signal recording / reproducing unit 211, and controls the video signal switch 208 and the audio signal switch. The video signal and audio signal from 209 are recorded respectively. At the same time, the timer microcomputer 203 applies a control signal to the video signal switch 208 and the audio signal switch 209 to convert the video signal and the audio signal from the tuner 206 (or the external terminal 207) into the video signal recording / playback unit 2. 10 and audio signal recording / playback unit 211. As a result, the provided video signal and audio signal are recorded in the video signal recording / reproducing unit 210 and the audio signal recording / reproducing unit 211, respectively.

However, if the command signal input by the user is to watch a TV broadcast, the timer microcomputer 203 does not transmit any information to the servo / system controller 204. However, the tuner 206 is controlled so as to select the TV broadcast, and the video signal switch 208 and the audio signal switch 209 are controlled so that the video signal and the audio signal included in the selected TV broadcast are imaged. The signal is transmitted to the signal processing unit 213 and the audio signal processing unit 214.

Similarly, when the user wants to view the video information and the audio information included in the video signal and the audio signal from the external terminal 207, the timer microcomputer 203 operates the video signal switch 208 and the audio signal. The signal switch 209 is controlled to transmit the image signal and the audio signal to the video signal processing unit 213 and the audio signal processing unit 214, respectively.

First, if the VCR unit fails and no signal is transmitted from the servo / system controller 204 to the timer microcomputer 203, or if information indicating that the VCR unit has failed is transmitted, the recording and / or reproduction is performed. The operation is not the same as in conventional TVCRs. Therefore, when such a failure of the VCR unit occurs, if the command input by the user is related to the VCR operation such as recording and reproducing, the timer microcomputer 203 ignores it.

However, unlike the conventional TVCR, if the command input by the user is to watch the TV broadcast, such an operation does not include any component of the VCR unit, and thus the method described above is used. Is successfully done in. Similarly, when the user wants to view the video and / or audio information contained in the video and / or audio signal from the external terminal 207, such an operation is successful regardless of whether the VCR section is broken or not. Done behind the scenes.

On the other hand, if the VCR unit fails, the timer microcomputer 203 can transmit a signal to the VCR power switch 216 to cut off the AC power to the VCR.
