Description

Broadcast data automatic memory display method

The present invention extracts and stores a broadcast station name or a broadcast station name and a broadcast program corresponding to a channel by using KBPS (Korean Broadcasting Program System) data transmitted from a broadcast station, and then tunes the channel in which the viewer is stored. The present invention also relates to a broadcast data automatic memory display method for displaying a broadcast station name and a broadcast program so that a viewer can know broadcast data corresponding to a current channel.

In the conventional TV, when the automatic channel is set, all channels are tuned by one channel, and the AFT voltage inputted from the intermediate processing unit is a synchronization signal. When the change is made, only the stored channel is tuned so that the viewer can select the desired channel.

At this time, in order for the viewer to know the broadcast station name of the current channel, the viewer inputs the broadcast station name corresponding to the channel.

After that, when the channel is changed, the TV reads the data input by the viewer and displays the name of the broadcasting station corresponding to the changed current channel as an OSD on the screen.

As described above, in the conventional TV, the broadcast station name display method allows the viewer to input the broadcast station name corresponding to the channel one by one using the key operation, and then whenever the channel is changed using the OSD font, Based on the data entered, the station name of the corresponding channel is displayed on the screen.

In such a conventional method, since the viewer manually inputs the name of the broadcasting station, the error of the viewer is likely to occur, and operation inconvenience is accompanied.

The present invention is to solve the above problems, when the viewer switches the channel using the KBPS data transmitted with the broadcast signal from the broadcast station, so that the broadcast data corresponding to the switched channel can be displayed on the screen It is intended to facilitate the user's convenience.

First, the configuration of an apparatus for realizing the automatic memory data displaying method according to the present invention will be briefly described with reference to FIG.

A tuner / IF unit 2 which receives and tunes a broadcast signal received through the antenna 1 and tunes a channel, and a broadcast signal that is tuned by the tuner / IF unit 2 and converted to an intermediate frequency is converted into an image signal ( V / and the audio / video separation unit 3 which separates the audio signal A, and the microcomputer which controls each unit by receiving the synchronization signal SYNC and the AFT voltage output from the video / audio separation unit 3 (4), an image processing unit (5) for processing the image signal (V) output from the video / audio separation unit (3) to be displayed through the CPT (6), and the video / audio separation unit (3) a KBPS decoder unit (7) which receives video signals from (3) and decodes KBPS data; a memory unit (8) storing data decoded by the KBPS decoder unit (7); It consists of a key input unit 9.

The KBPS decoder 7 is a data slicer 7A and a data slicer for processing data by slicing KBPS data among VBI lines of an image signal input without a separate memory. The data decoded by the western portion 7A is fetched to determine and process broadcast data packets, and the data is controlled by the KBPS controller 7B and the KBPS controller 7B to perform input / output control with the outside. The OSD processing unit 7C is configured to OSD process KBPS data decoded by the slicer unit 7A and output the same to the image processing unit 5.

The present invention broadcast data automatic memory display method is realized by the apparatus configured as described above. In the broadcast data automatic memory display method according to the present invention, the first embodiment of the present invention uses the data slicer unit 7A during automatic channel switching. The decoded KBPS data is patched by the KBPS control unit 7B to process only broadcast station name data packets so that a user can display only the broadcast station name for the corresponding channel when switching channels. FIG. 2 is a diagram illustrating the first embodiment of the present invention. FIG. 3 is a flowchart showing a process of storing and storing a broadcast station name in automatic channel setting. FIG. 3 is a flowchart showing a process of displaying a broadcast station name OSD when switching channels according to the first embodiment of the present invention. Referring to FIG. 3 and FIG. 3, the process, actions, and effects of the first embodiment of the present invention to be made in the configured microcomputer 4 will be described. And the like.

First, in the first embodiment of the present invention, the process of storing and storing the name of a broadcasting station when the channel is set includes initializing the data and address counters stored in the memory unit 8 when the automatic channel setting key is input, and then temporarily storing the current channel number. The first step of the step is to sequentially tune all channels from the temporarily stored current channel number to the current channel number again to determine the presence or absence of the signal, and if there is a signal to store the channel number and data in the memory address And a third process of comparing a channel number and data stored in a memory address when switching channels, and displaying a broadcast station name corresponding to the switched channel with an OSD.

In the third process, when the channel change key is input, the third process tunes to the changed channel, initializes the memory address counter, and reads the memory address and data. Step 5 is to compare the read data with the data of the current channel number. If the read data is the same as the data of the current channel number, the station name data is read from the address and the corresponding station name is displayed on the OSD. The sixth step to be given; and the data to be read as a result of the comparison of the fifth step and the data of the current channel number are different from the address of the read data to the seventh step to repeat the fifth step sequentially and to the initialization address. Repeat step 5 to display the current channel number if there is no address data like that of the current channel number. It made of an eighth process of the display.

In the sixth step, it is determined whether the read data is normal, and if the read data is normal, the OSD is displayed, and if it is not normal, the current channel broadcasting station name is immediately changed by the KBPS decoder 7. After reading and storing the data, the display is performed by the OSD.

In general, the broadcast time, the program guide, and the broadcast station name are included in the KBPS data transmitted along with the broadcast signal. In the first embodiment of the present invention, only the broadcast station name packet of the KBPS data is determined and used. If the data slicer 7A of the KBPS decoder 7 slices the KBPS data in the VBI line of the video signal and outputs it to the KBPS controller 7B, the KBPS controller 7B patches the decoded data in this manner. To judge and process only the station name data packet so as to control and output the OSD processor 7C.

When the viewer sets the automatic channel, the microcomputer 4 tunes in increments of one channel, stores the channel number with the signal, and processes the broadcasting station name of the stored channel number as described above. It is received from and stored in the memory address.

As described above, all channels are tuned to increase the memory address by one, and stored in each order as shown in FIG.

In this way, the name of the broadcasting station for the channel number is stored and stored. When the viewer later switches channels, the user tunes to the changed channel and simultaneously executes the following process.

The memory address counter is reset, and the memory address and the data stored in the memory address are read.

The data read above is compared with the data of the current channel number to be switched, and all memory addresses are searched until there is data equal to the current channel number.

In this way, if there is no data like the data of the current channel number in all memory addresses, only the current channel number is displayed in the OSD.

If the read data has the same data as the current channel number, the broadcast station name is read from the read data, and it is determined whether the read broadcast station name data is normal.

As a result of the determination, if the read data is normal, the corresponding station name is displayed on the screen by OSD processing. If the read data is not normal, the broadcast station name of the current channel switched by the KBPS decoder unit 7 is read again.

The data read in this way is stored in the memory unit 8 and displayed on the screen by OSD processing to notify the viewer.

As described above, the first embodiment of the present invention recognizes and stores broadcasting station names for each channel number during automatic channel setting, and the viewer automatically reads the broadcasting station name corresponding to the channel number every time the channel is switched and displays the OSD automatically. In this case, the user's convenience is provided, and since only the broadcast station name data packet is judged and processed, it can be processed using the buffer register of the KBPS control unit 7B, thereby eliminating the need for a separate memory. It is.

Meanwhile, the second embodiment of the present invention deviates from the limitation of displaying only the name of a broadcasting station in the first embodiment of the present invention, and each time the viewer switches channels, the switched channel stores the broadcast data before the viewer broadcasts. When the channel where the data is stored is switched, the broadcasting station name and broadcasting program title of the corresponding channel can be displayed, and the broadcasting station name and broadcasting program title are automatically memorized and displayed according to the second embodiment of the present invention. The process will be described with reference to FIG.

When the channel switching key is input, the first process of determining whether the KBPS data of the switched channel is stored by switching to the corresponding channel to be input, and if the KBPS data of the switched channel is stored as a result of the first process determination, is stored. The second process of reading the KBPS data of the switched current channel and displaying the program title and the name of the broadcasting station compared to the current time, and the KBPS data of the channel switched as a result of the determination of the first process is not stored. If not, a third process of displaying only the current channel number and receiving and storing KBPS data for the switched channel is performed.

According to the second exemplary embodiment of the present invention, the KBPS data is automatically stored in the memory whenever the viewer switches channels, and when the viewer switches channels using the stored KBPS data, the KBPS data for the switched channels is stored. If the KBPS data of the channel switched by the viewer is stored in the memory section 8, the microcomputer 4 reads the KBPS data and reads the current time and the current time. On KBPS data will be compared.

As described above, the program title for the corresponding channel of the current time is recognized as compared with the current time, and the broadcast station name and the program title are displayed to the viewer.

However, if there is no KBPS data for the switched channel, only the channel number of the switched current channel is displayed to inform the viewer, and the KBPS data is received and stored in the memory.

That is, if the viewer has never watched the current channel that has been switched or if the viewer has never watched after changing the KBPS data included in the broadcast signal at predetermined intervals, only the number of the current channel is displayed. KBPS data is received and stored in memory.

Since the process is performed as described above, KBPS data is automatically stored in the channel watched by the viewer without the need to save KBPS data through a separate automatic channel setting process. By being displayed, not only the time of the automatic channel setting process is shortened but also the desire of the viewer can be solved.

On the other hand, Figure 6 is a third embodiment of the automatic memory display method of the present invention, it is to allow the viewer to display the program title and broadcast station name for the other channel on the screen of the current channel received by the channel for each channel When the monitor mode is set, the first step of determining whether KBPS data is stored for other channels by searching KBPS data of all other channels except for the current channel on the currently viewed broadcast screen; In the second process, the program title and station name being broadcasted are displayed in the state of the screen being viewed at the time compared to the current time only in the stored channel, and in the other channel in which the KBPS data is not stored in the first process. And a third step of displaying only the channel number in the screen state in which the user is watching. All.

In this manner, the third embodiment of the present invention relates to a monitor setting mode that enables a viewer to check broadcasting data of another channel in a screen state in which the viewer is watching. The KBPS data is searched to determine whether the KBPS data is stored.

If KBPS data is stored for the channel selected by the viewer in monitor mode, the viewer can display the broadcasting data of the channel selected by the viewer in monitor mode, that is, the station name and program title, compared to the current time. do.

At this time, if KBPS data is not stored for the channel selected by the viewer in the monitor mode, only the channel number selected by the viewer in the monitor mode is displayed in order in the screen state being viewed.

By doing this, the viewer can watch the current channel while being able to know what program is being broadcast on the other channel.

As described above, according to the present invention, the automatic memory display method of the present invention automatically stores the broadcast data using KBPS data, and then the viewer displays the broadcast station name or the broadcast station name and the broadcast program title when switching channels. The effect is to increase the convenience of use.
