TV system with automatic reservation program

The present invention relates to a TV system having an automatic viewing function of a reservation program, and more particularly, attaches a sensor that can detect a human body around the TV set so that the microprocessor can recognize and input a user's favorite program in advance. If you set it, you can control TV power and tuner automatically or control OSD screen (or sub-screen) output at the desired time according to the presence or absence of human body around the TV set to display the program of the channel reserved for the user's desired time for a certain time. In order to allow the user to conveniently watch the favorite program.

Conventionally, a TV system having an automatic power-on reservation function converts an AC input power into a DC power of a predetermined level as shown in FIG. 1 to supply main power required for driving a load, or to supply standby power to a microprocessor or other necessary parts, respectively. A DC power supply unit 21 and a main power switch unit 22 that is turned on or off by a control signal of a microprocessor controlled by a power switch operated by a user and supplies operating power to each part of the load.

The key input unit 40 converts each key value selected from the key matrix included in the remote controller or the set into an electrical signal corresponding thereto, and scans an output signal of the key input unit to recognize a user's key operation state. And a microprocessor 30 for selectively controlling the operation of each part of the system by outputting respective control signals, a memory unit 70 for storing a driving program of the microprocessor and data input from the outside; And an OSD processor 62 which generates and outputs a corresponding OSD character according to the control signal of the microprocessor.

Step 2 (S32-S41) of turning off the power and ending the program when there is no person or the program ending time for a certain time, and checking the program reservation time and the channel currently being viewed if the system power is on. If this reservation channel is matched, OSD signal for reservation guidance is superimposed If the current reception channel is not the reserved channel, the third channel (S42-S51) can be performed by tuning the reserved channel to output the sub-screen for a predetermined time.

At this time, the second step is performed when the system power is turned off in the first step. The twenty-first step S32-S35 determines whether the system power is driven by checking the presence / absence of the human body around the set and the program reservation time. When the program reservation time is reached when there is a person around the system as a result of the determination of the twenty-first step, the twenty-second step (S36) of broadcasting the set channel by turning on the system power, and the program termination time and It is preferable that the twenty-third step (S37-S41) is performed to continuously check the presence / absence of the human body around the system and turn off the power when there is no person or the program end time for a certain time.

The third step is a step that is performed when the system power is turned on as a result of the determination of the first step. In operation S42, the program reservation time is determined. In operation 32, it is determined whether the channel currently being viewed is a channel of the reserved program. If the channel currently received matches the reserved program channel, the OSD character is overlapped with the broadcast signal for a predetermined time. Step 33 (S44-S47) of outputting and ending the operation; and step 34 of outputting and terminating the sub-screen by tuning the reserved channel for a predetermined time when the currently received channel is not the reserved program channel as a result of the determination of the 32nd step. It is preferable that it consists of (S48-S51).

The operation of the present invention as described above is as follows.

First, the present invention performs a first step of determining whether to watch TV currently by checking the power driving state of the TV system in a state where a user inputs a program time and channel preferred (S31).

At this time, if the power is turned off (Y branch of S31) as a result of the determination of the first step, the microprocessor 30A checks the voice recognition signal output from the voice detector 80 (S32). Determine if there are people around the TV set or not.

The voice detection unit 80 recognizes the voice signal output for a predetermined time (for example, 10 minutes) from the program scheduled time, if there is a new voice signal (Y branch of S34) to drive the TV power and set the channel Synchronizes the scheduled broadcast program (S36) and checks the reserved program end time and the presence / absence of the human body during the broadcast (S37, S39) to recognize the voice over the program time or for a certain time (for example, 10 minutes) If a signal is not detected (Y branch of S40), the power consumption can be reduced by performing a second step of automatically turning off the power. The power supply will not be driven.

If it is determined that the TV is in the first stage (N quarter of S31), it is determined whether it is a reserved program time (S42). Determine (S43).

At this time, if the currently received channel matches the reserved channel (Y branch of S43), a message for notifying the channel and time of the program set on the OSD screen is superimposed on the TV screen for a certain time (for example, 3 minutes) and outputted ( S45, S46) and then outputs the OSD text screen (S47).

On the contrary, if the currently received channel does not match the reserved channel (N branch of S43), the reserved program synchronizes the set channel and displays the sub-screen for a certain period of time (for example, 3 minutes). After outputting (S49, S50), the sub-screen output is blocked (S51).

According to the present invention as described above according to the user's favorite program in advance to control the TV power and tuner automatically at the desired time according to the presence or absence of the human body around the TV set, or to control the message output to the OSD screen or sub-screen Therefore, the user can conveniently watch a program of a reserved channel at a desired time.
