Apparatus for controlling indoor antenna power supply of broadcasting receiver

The present invention relates to an indoor antenna power supply control apparatus for a broadcast receiver such as a digital television (D-TV) or a set-top box (STB) to which an indoor antenna with an adapter or an indoor antenna without an adapter is connected and connected.

In general, various types of broadcast receivers, such as digital televisions or set-top boxes, may be used by connecting an indoor antenna having an adapter for power supply or an indoor antenna having no adapter.

For example, as shown in FIG. 1, the broadcast receiver includes a power supply unit 10, a switch 11, a tuner 12, a protection circuit 13, a CPI 14, and a GUI. The generation unit 15 and the like are configured to be included.

On the other hand, any one of the indoor antenna 20 is connected through the RF input port (RF_IN) of the tuner 12, for example, in the CPI 14, according to the user's request, An operation of the Graphic User Interface (GUI) generating unit 15 is controlled to generate and display a graphic image screen of a user selection menu.

In addition, the CPI 14 confirms a menu item selected by a user through a graphic image screen of the user selection menu. For example, 5 V is supplied as a driving power of an indoor antenna or not. Whether or not to choose is determined by the user's choice.

For example, when the user connects and connects the indoor antenna 20 without an adapter to a broadcast receiver, and designates to supply 5V as driving power of the indoor antenna through the graphic image screen, In 14, the switch 11 is turned ON.

Accordingly, the 5V power output from the power supply unit 10 is input to the 5V input port 5V_IN of the tuner 12 and then connected to and connected through the tuner RF input port RF_IN. 20), it is used as a driving power for the indoor antenna.

On the other hand, when the user connects and connects an indoor antenna (not shown) equipped with an adapter to a broadcast receiver, and specifies that the driving power of the indoor antenna is not supplied through the graphic image screen, the CPI 14 ), The switch 11 is turned OFF.

Accordingly, since the 5V power output from the power supply unit 10 is not input to the 5V input port 5V_IN of the tuner 12, the indoor antenna connected and connected through the tuner RF input port RF_IN. The driving power is prevented from being unnecessarily supplied to (20).

 However, if the power supply of the indoor antenna is incorrectly selected due to carelessness of the user, for example, after connecting and connecting an indoor antenna without an adapter to the broadcast receiver, the user does not select a menu item for power supply. If not, the indoor antenna will not operate normally. On the contrary, if the indoor antenna equipped with an adapter is connected to the broadcast receiver and the user does not select a menu item for power off, the indoor antenna is unnecessarily powered on. There is a problem with the supply.

According to the present invention, a broadcast receiver such as a digital television (D-TV) or a set-top box (STB) detects whether or not a separate adapter is provided in an indoor antenna connected through a tuner's RF input port. If no adapter is provided, the broadcast receiver supplies driving power required for the indoor antenna to the broadcast receiver, and if a separate adapter is provided, the broadcast receiver for supplying the drive power required for the indoor antenna to the broadcast receiver is not provided. To provide an indoor antenna power supply control device.

An indoor antenna power supply control apparatus for a broadcast receiver according to the present invention includes: detecting means for detecting whether an indoor antenna connected and connected through an RF input port of a tuner uses driving power supplied by itself; And switching means for supplying or blocking driving power required for the indoor antenna according to the detection result.

The detecting means may detect whether the indoor antenna uses driving power supplied by itself through a separate adapter when the system is booted or connected to an indoor antenna.

In addition, the detecting means, by comparing the voltage of the front and rear ends of the protection circuit provided on the connection line of the RF input port and the indoor antenna of the tuner, characterized in that the switching means on / off,

The switching means may be turned off by the detection means to cut off the power input to the tuner when the indoor antenna uses driving power supplied by itself through a separate adapter. ,

The switching means may be turned on by the detecting means to supply power to the tuner when the indoor antenna does not use the driving power supplied by itself through a separate adapter as a result of the detection. ,

In addition, the driving power required for the indoor antenna is characterized in that it is supplied through the RF input port of the tuner,

The detecting means may be a logic element of an or gate, and the switching means may be an on / off switch.

The indoor antenna power supply control apparatus of the broadcast receiver according to the present invention detects whether or not a separate adapter is provided in the indoor antenna connected to and connected through the tuner's RF input port. If no adapter is provided, the drive power required for the indoor antenna is supplied by the broadcast receiver, and if a separate adapter is provided, the drive hardware required for the indoor antenna is not supplied by the broadcast receiver. By providing the circuit in the broadcast receiver, it is possible to prevent the error that the driving power required for the indoor antenna is not supplied due to user's carelessness, or the driving power is unnecessarily supplied to the indoor antenna having a separate adapter. You can do it.

Hereinafter, a preferred embodiment of an indoor antenna power supply control apparatus of a broadcast receiver according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention is applied to various types of broadcast receivers in which an indoor antenna with an adapter or an indoor antenna without an adapter is connected and used. For example, as shown in FIG. 3, a broadcast to which the present invention is applied. The receiver includes a power supply unit 10, a switch 11, a tuner 12, a protection circuit 13, an antenna voltage detector 16, and the like.

On the other hand, the indoor antenna 20 without an adapter is connected or connected through the RF input port RF_IN of the tuner 12 or the indoor antenna 30 with the adapter is connected.

In addition, the antenna voltage detector 16 detects a voltage applied to the front and rear ends of the protection circuit 13, respectively, for example, when the broadcast receiver is booted or connected to an indoor antenna. It turns on / off (11).

For example, as shown in FIG. 3, when the indoor antenna 20 without an adapter is connected and connected, 0V voltage is detected at the front and rear ends of the protection circuit 13, respectively. The antenna voltage detection unit 16 outputs a control signal of a low pulse to the switch 11 so as to be in an ON state.

Accordingly, the 5V power output from the power supply unit 10 is input to the 5V input port 5V_IN of the tuner 12 and then connected to and connected through the tuner RF input port RF_IN. 20, it is used as a driving power source for the indoor antenna 20.

On the other hand, as shown in Fig. 4, when the indoor antenna 30 with the adapter is connected and connected, 0V voltage is detected at the front end of the protection circuit 13, and 5V voltage is detected at the rear end. In this case, the antenna voltage detector 16 outputs a high pulse control signal to the switch 11 so as to be in an OFF state.

Accordingly, since the 5V power output from the power supply unit 10 is not input to the 5V input port 5V_IN of the tuner 12, it is possible to prevent unnecessary supply of driving power to the indoor antenna 30. Done.

On the other hand, the antenna voltage detection unit 16 may be a logic element of a simple OR gate, and the like, for example, when the indoor antenna 20 without an adapter is connected and connected, the OR Voltages applied to the front and rear ends of the protection circuit 13 are applied to both sides of the gate.

Since the RF input port RF_IN of the tuner outputs a 0V voltage as a default voltage, and since there is no separate driving power supply to the indoor antenna, 0V voltage is applied to both sides of the or gate, A low pulse of 0 V is output to the switch 11 to be in an ON state.

On the other hand, as shown in FIG. 6, when the indoor antenna 30 having an adapter is connected and connected, voltages applied to the front and rear ends of the protection circuit 13 are applied to both sides of the OR gate. .

The RF input port RF_IN of the tuner outputs a 0V voltage as a default voltage, and since the indoor antenna has a separate driving power supply, 0V voltage and 5V voltage are applied to both sides of the OR gate. Therefore, a high pulse of a 5V voltage is output to the switch 11 to be in an OFF state.

Accordingly, even if the user does not manually select whether to supply power to the indoor antenna, it is possible to automatically supply or cut off driving power required for the indoor antenna.

For reference, the antenna voltage detector may use various circuit elements other than the logic element of the OR gate.

Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.
