The present invention relates to a method for controlling a K program display, and more particularly, to a method for controlling a K program display for searching for K program information of another broadcasting channel without changing a channel being viewed.

The K program is broadcast information included in data transmitted by carrying data encoded by a broadcasting station in a broadcast signal so that a user can easily use information on a broadcast program according to a reserved recording or broadcast time.

In general, each broadcasting station transmits only broadcast program information transmitted from its own broadcasting station on the broadcasting signal of the corresponding channel.

Therefore, when the broadcast signal is directly turned on in order to use broadcast program information while the broadcast signal is being viewed, the broadcast channel of the received channel is displayed on the screen.

According to the conventional bar program display control method, in order to view bar program information of another channel from the channel of the currently viewed broadcast, change the channel from the bar K off state to the channel for displaying bar information immediately after There was a cumbersome operational problem to turn K on.

Accordingly, an object of the present invention is to provide a bar K program display control method for displaying a bar K program of another channel without changing the viewing channel in order to solve the above problem.

In order to achieve the above object, the direct K broadcast program display control method according to the present invention repeatedly checks a power mode and generates a control signal when a power signal is switched from a power off mode to a power on mode.

OFF command is entered Immediate K-off command confirmation process to terminate the process, if the channel-up / down command is not input when the immediate K-off command is not input, and if the channel up / down command is not input, the channel is repeated again from the decoding process. When a channel up / down command is input as a result of the up / down check process and the channel up / down check process, the searched up / down channel data among the stored program information data is searched for, and then the area to be read from the second and third memories is searched. After the designation, it is characterized in that it comprises the step of repeating the decoding process again from the channel data region.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart of a method for controlling a direct K broadcast program according to the present invention.

According to the present invention, a method for controlling a direct K broadcast program display includes a power mode conversion check process 110 for determining whether a power mode is switched from an off mode to an on mode, and channel data for extracting and storing data in a channel from broadcast program information data. A storage process 120, a start code check process 130 for searching for a start code of an input broadcast program packet, a packet data storage process 140 for storing input packet data in a memory, and an end code of an input broadcast program packet End code checking process 150 for searching for, channel changing process 160 for changing broadcast program information to a received broadcast channel, channel comparison process 170 for comparing input channel data and stored channel data, and K K command confirmation process 180 to check whether the on command is input, during the input broadcast program information A data packet detection process 190 for detecting a data packet having information of a current time and a broadcast station name, a data storage process 200 for storing the detected data in a memory, and a data extraction process 200 for reading KBPS data stored in the memory A data extraction process 210 for reading the KBPS data stored in the memory, a decoding process 220 for decoding the extracted data, a display process 230 for displaying the information of the decoded data, and whether a K-off command is inputted. K-off confirmation process 240 for checking, channel up / down checking process 250 for checking whether a channel up / down command is input, channel for searching an area of stored program information data for the up / down channel A data region verification process 260 is provided.

The present invention is characterized by using broadcast program information data included in encoded data transmitted by being multiplexed on television broadcasting.

Data broadcasting refers to a broadcasting system that transmits various types of digitally encoded information that does not exist in an audio signal or a video signal, and includes teletext, a video program system (VPS), a video programmed video recorder (VPV), and a Korean broadcasting program system (KBPS). ) Has been put to practical use.

Data broadcasting adopts a highly compressed encoding method to transmit various types of information, compared to voice broadcasting or television broadcasting, and thus high efficiency transmission is possible.

In data broadcasting using voice signals, signals are modulated by a minimum shift keying (MS) signal at low frequencies in AM, and carriers are installed above the subchannel in FM to transmit data.

KBPS broadcast data is output after setting an arbitrary line according to the conditions of each broadcasting station during the VBI (Vertical Blanking Interval) period, selecting and inserting one of odd or even fields among the set lines.

The structure of KBPS data can be divided into three parts: a synchronization signal part, a data header part, and a data packet part.

The synchronization signal unit is used to generate a reference signal for synchronizing the data clock received at the receiver to detect the exact position of the received data.

The data header portion is used to confirm the continuity of the input video signal.

The data packet unit is a bundle of data classified into various types of broadcast program information.

As an example, packet 1 includes data having information on a current time, a broadcaster name, and ON-AIR KBPS, and packet 4-7 includes data including broadcast information of 1-4 weeks. exist.

1 illustrates a method of controlling display of broadcast program information on a screen using KBPS data.

The power mode conversion confirmation process 110 is a process of confirming that the state of the power source is switched from the off mode to the on mode.

That is, when the power is switched from the standby mode in which the power is turned off to the power-on mode in which the power is supplied, it detects this and generates a control signal.

The channel data storing process 120 is a process of inputting broadcast program information data, extracting data having channel information, and storing it in a memory when a control signal generated when the power mode is switched from the off mode to the on mode is applied. .

The start code verification process 130 is a process of confirming a start code of each packet having broadcast program information among input data.

When the start code of the packet having the broadcast information is confirmed, the packet data storage process 140 is executed, and the packet data storage process 140 is a process of storing data having broadcast program information contained in an input packet in a memory.

In this process, data constituting a packet having broadcast program information is continuously stored until the AND code of the last packet is input.

The end code checking process 150 checks the data of the input packet to check whether the end code for notifying the end of data of the packet is input.

If the AND code is broken during this process, it means that all broadcast program information on the current channel has been received and stored in the memory.

The channel changing process 160 performs up / down of a channel to a channel through which KBPS data is received in order to receive KBPS data having broadcast program information of another channel after checking the input of the AND code.

After performing the channel up / down, the channel comparison process 170 is executed. The channel comparison process 170 compares the channel data stored in the channel data storage process 120 with the channel data input after the channel up / down execution. It's a process.

If the input channel data is the same as the channel data stored in the memory, it means that the KBPS data of all the channels are completed and stored in the memory by up / down the channel. In this case, the K command check process 180 is immediately executed. .

However, if the input channel data is not the same as the channel data stored in the memory, it means that the data having the broadcast program information for the channel into which the KBPS data is currently input is not stored in the memory. The start code check process 130 is repeated to store the broadcast program information data in the same manner as the method for storing the broadcast program information data of all channels up / down.

The direct K command confirmation process 18 executes processes of storing broadcast program information data for all channels to which KBPS data is input into the memory, and then executes a key of the short K on command for displaying broadcast program information stored in the memory. It is the process of repeatedly checking whether is inputted.

If a K on command is input, the data packet detection process 190 is executed.

The data packet detection process 190 is a process of detecting a data packet having information on a current time and a broadcast station name among input data packets.

The data storage process 200 is a process of storing data of the packet detected in the data packet detection process 190.

The data extraction process 210 is a process of reading data on broadcast program information of a current channel stored in a memory.

The decoding process 220 is a process of decoding the encoded data read in the data extraction process 210.

The display process 230 is a process of displaying the decoded KBPS data on the screen until immediately before the K off command is input.

The immediately K-off confirmation process 240 is a process of confirming the immediate K-off command to be input when the user wants to stop executing the immediately K-screen display.

If a K off command is input immediately, execution of the screen display of the program information is stopped, and the display returns to the normal viewing mode.

The channel up / down check process 250 is executed in the immediate K on state in which the immediately K off command is not input.

The channel up / down confirmation process 250 is a process of confirming whether it is desired to use broadcast information input to a channel different from the current channel in the K on state.

Therefore, when the channel up / down is performed immediately in the K-on state, the channel data area check process 260 is executed.

The channel data area checking process 260 is a process of searching for an area of the memory in which the broadcast program information data of the up / down changed channel is stored among the broadcast program information data stored in the memory. When the search for the memory area is completed, the program information for the changed channel is repeatedly displayed on the screen from the data extraction process 210.

Therefore, if you execute the channel up / down without changing the current channel you are watching, the program information of the up / down channel can be displayed.

As described above, according to the present invention, data having broadcast program information is stored in a memory for each channel, so that the K broadcast program information of another channel can be used directly in another channel without changing the viewing channel.
