Abstract

PURPOSE: A broadcast signal receiver capable of automatically changing a broadcast channel according to set information is provided to easily watch a broadcast program of a predetermined channel by controlling a tuner regardless of an on and off state of a television. CONSTITUTION: In the case that a TV is turned on, a microcomputer(300) counts a time set in the TV and compares the time with time information of channel change information stored in a storage unit(400) while controlling a tuner(120) according to signals inputted through a key input unit(520) and a sensor(540). If the time and the time information coincide, the microcomputer controls the tuner to change the current channel into a broadcast channel set from a received broadcast signal. A speaker(620) and a screen(640) output a broadcast program corresponding to the channel change information. In the case that the TV is turned off, the microcomputer compares the time set in the TV with the time information of the channel change information. If the time and the time information coincide, the microcomputer turns on the TV and controls the tuner to change the current channel into a channel corresponding to the channel change information.

Description

Broadcasting signal receiver for capable of switching broadcasting-channel automatically according to predetermined information}

The present invention relates to an apparatus for receiving broadcast signals, such as a television. More specifically, the apparatus can output a broadcast channel switched to a broadcast channel set at a predetermined time through a tuner while the broadcast channel tuned by the tuner is being output. The present invention relates to a broadcast signal receiving apparatus.

In general, a television tunes a broadcast channel corresponding to a channel tuning command input from a broadcast signal transmitted through wired / wireless through a tuner and outputs the tuned broadcast channel through a speaker and a screen. The viewer can watch the broadcast channel to be watched by using the channel switching key provided on the remote controller and the external panel. Meanwhile, the viewer may reserve a specific broadcast program that he or she wishes to watch through a broadcast program listing table provided from a broadcasting station. Accordingly, the conventional television sets the current time and the reserved time in the power-on state according to the input signal, and counts the time based on the current time set in the power-off state. When the counted time coincides with the set reservation time, the television is turned on and outputs the broadcast channel tuned from the tuner at the set reservation time. In this case, the reservation time set by the viewer may be on and off of the television, and the off time may be set to be selectively performed by the viewer. Such a conventional television is possible in a state where a channel is switched to a broadcast channel including a broadcast program to be watched when reserving a specific broadcast program.

However, a conventional TV having a reserved on / off function does not perform the reserved on / off function set in a power-on state. Accordingly, in the state where the television is turned on, the viewer may be inconvenient to watch the time when the broadcast program to be watched is transmitted from the broadcasting station and change the channel through the channel switching key provided on the remote controller and the external panel. On the other hand, when the viewer does not know the channel on which the preset broadcast program is broadcast, there is a problem in that the television is turned off before the set time and the user waits until the power is turned on according to the set time.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a television that can tune and output a broadcast channel of a broadcast program to be watched at a set time regardless of whether the TV is powered on or off.
