BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video apparatus, and more particularly, to an apparatus and method for displaying a progress amount of a broadcast program for displaying a progress amount of a broadcast program on a screen.

Generally, broadcast stations transmit program guide information such as start and end times, program names, and contents of a program and current standard time information in addition to a broadcast program, and the viewer performs reservation recording or the like using the program guide information and the current standard time information.

FIG. 1 is a block diagram showing a configuration of a satellite broadcast receiver for receiving conventional program guide information. In the broadcast signal received through the antenna 1, only one broadcast signal is selected through the channel decoder 2, Is input to the multiplexing unit (3) and demultiplexed.

The broadcast schedule information extracting unit 6 extracts broadcast schedule information from the output of the demultiplexing unit 3 and inputs the broadcast schedule information to the control unit 7. The control unit 7 controls the output of the broadcast schedule information extracting unit 6 And controls the demultiplexing unit 3 and the A / V decoder 4 and the display unit 5 according to key inputs such as a user's program schedule and scheduled recording so that the output of the A / V decoder 4 And is displayed on the display unit 5.

Meanwhile, as the broadcasting and the digitization of the broadcast are accelerated, the user has a lot of channels. For example, in the United States, the number of broadcasting channels is 100-200, and the user uses the program guide information to perform the reserved recording and the reserved viewing do.

However, as the number of broadcast channels increases, the opportunity for channel change increases. However, conventionally, it is difficult to check whether the program selected by the user is currently in progress or not.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus and method for displaying a progress amount of a broadcast program, which can inform the progress of a broadcast program using broadcast schedule information transmitted from a broadcast station.

According to an aspect of the present invention, there is provided an apparatus and method for displaying an amount of progress of a broadcast program indicating whether or not a broadcast program selected by a user is being broadcast in a program guide mode.

Another aspect of the present invention resides in an apparatus and method for displaying a progress amount of a broadcast program for detecting a start time and a duration of a broadcast program and comparing the start time and the duration with a current time to display a broadcast progress amount in real time.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to the accompanying drawings.

FIG. 2 is a block diagram of an apparatus for displaying the progress of a program according to the present invention. The apparatus includes a channel decoder 12 for selecting one of broadcast signals received through an antenna 11, a channel decoder 12 V decoder 14 for decoding the A / V output of the demultiplexer 13, and a demultiplexer 13 for demultiplexing the A / V decoder 14, A broadcast schedule information extracting unit 16 for extracting broadcast schedule information from the output of the demultiplexing unit 13 and an output of the broadcast schedule information extracting unit 16, A program start and duration extraction unit 17 for extracting a program start time and a duration time information from the output of the demultiplexer 13, A calculation unit 18, The demultiplexer 13, the A / V decoder 14, and the display unit 14 in accordance with the program start and duration extraction unit 17, the standard time extraction and current time calculation unit 18, And a control unit 19 for controlling the control unit 15.

The method of displaying the program progress time according to the invention thus constructed will be described with reference to FIGS. 3 and 4. FIG.

First, only one broadcast signal is selected from the broadcast signal received through the antenna 11 through the channel decoder 12, and is input to the demultiplexer 13 and demultiplexed.

The broadcast schedule information extracting unit 16 extracts broadcast schedule information from the output of the demultiplexing unit 13 and extracts start time and duration time of each program from the output of the broadcast schedule information extracting unit 16 Extracts standard time and current time from the standard time extraction and current time calculation unit 18, and inputs the standard time extraction and current time to the control unit 19.

The control unit 19 determines whether a progress key has been input from the user's key input. If it is determined that the progress key has been input, the control unit 19 determines whether the progress flag in the control unit 19 is turned on (S1, S2).

If it is determined that the progress flag is on, the broadcast progress status display is disabled, the progress flag is turned off, and the process ends (S3, S4).

If it is determined that the progress flag is not on, the start time and the duration of the specific program extracted by the program start and duration extracting unit 17 are inputted from the output of the broadcast schedule information extracting unit 16 (S5) (S6) a value obtained by calculating the current time using the standard time extracted from the standard time and broadcasted from the current time calculation unit 18.

In step S7, a percentage of broadcasting is calculated from the start time, the duration, and the current time in step S7. The display unit 15 displays the progress percentage in step S8.

On the other hand, if the progress bar is not displayed, the progress display of the program is off and the progress bar is displayed, the progress of the program is being displayed .

In addition, if the user wants to know the broadcast time and the remaining time, the broadcast time and the remaining time are displayed.

As described above, according to the present invention, the progress of a program currently being watched or recorded is displayed using broadcast schedule information and current standard time information, thereby facilitating user's broadcast selection.
