IMPROVED METHOD FOR DISPLAYING CHANNEL INFORMATION IN SATELLITE BROADCASTING RECEIVER}

The present invention relates to a satellite broadcast receiver, and more particularly, a satellite broadcast receiver suitable for providing a user with various types of menu screen guide information such as channel information received through a satellite channel and broadcast program information of each channel with an advertisement. An improved method of displaying channel information in.

In recent years, the broadcast method using satellites, which is rapidly expanding in use, is a method of providing broadcast signals to a wider area by using satellites (communication satellites) located at an altitude of about several tens to hundreds of kilometers from the surface of the earth. In this satellite broadcasting system, for example, an old band RF signal having a frequency band of 11.7 GHz to 12.0 GHz is used.

To this end, an antenna for satellite broadcasting reception is provided with a low noise blockdown converter for converting a radio frequency (RF) signal into an intermediate frequency (IF) signal, which is a high frequency RF signal. Is converted into an IF (intermediate frequency) signal in the hundreds to thousands of MHz bands (e.g., 950 MHz-2050 MHz) receivable by a satellite broadcasting receiver (receiver).

Therefore, in the satellite broadcasting tuner provided in the satellite broadcasting receiver (receiver), the user selects and tunes a channel selected by inputting an IF signal received through a low noise converter. Along with the improvement of signal quality and the ease of transmitting additional digital service data, the significant improvement of the user interface is a big advantage.

Meanwhile, in satellite broadcasting, a transmission signal of a digital broadcasting signal received from a satellite through a fixed channel to a satellite broadcasting receiver is restored to a transport stream through a process of converting to an intermediate frequency, demodulating, and correcting an error. The transport stream includes program service data such as television broadcasting and data broadcasting, and program guide data.

That is, satellite broadcasting transmits data to the satellite broadcasting receiver through packet aging based on the MPEG-2 standard, for example, in a 188-byte packet stream. The packet is largely a program guide packet and a program service data packet. Each packet includes 4 bytes of header information.

Herein, the program guide packet includes a channel information packet having program combination table (PAT) information including N-bit program identifier (PID) information (eg, 13-bit program identifier) indicating a program number of each channel. A program information packet having program map table (PMT) information of N-bit program identifier (PID) information meaning audio, video, text, etc. of a specific channel; and the program service data packet includes audio data of each channel. Packet, a video data packet, a text data packet, and the like, wherein program guide packets are continuously inserted and transmitted at intervals of several seconds between program service data packets.

Therefore, the satellite broadcasting receiver extracts program guide packets inserted at intervals of several seconds between program service data packets based on the header information (that is, PID) when the power is turned on by the user. (I.e., channel guide information and channel identifier (CID), program information and program identifier (PID), text information and text identifier (TID), etc.) for each channel are stored in the memory area of the satellite broadcasting receiver. In more detail, the program guide information includes a channel ID, a program name, a start time and a broadcast time of a program, a grade of a program, a voice mode, and the presence or absence of paid broadcasting.

The program guide information stored in the memory area as such is then used to tune a particular channel selected in the transport stream received over the satellite channel when a particular channel is selected by the user, and also by the user. When the provision of broadcast program information of the channel (i.e., display) is requested, it is composed of a menu screen and displayed on the monitor. Here, the present invention relates to an improvement of a technique for providing channel information and program information of each channel on a monitor according to a user's request.

That is, in the conventional satellite broadcasting receiver, when there is a request signal of a program guide menu screen from a user, the channel information stored in the memory area and the program information of the corresponding channel (that is, the channel information and the program information that can be displayed on the monitor) are displayed. Using a graphical tool prepared for withdrawal, a menu screen in the form of letters as shown in FIG. 5 is configured as an example, and then displayed on a monitor.

Therefore, users can view or search for programs that are to be broadcasted or broadcasted in each channel through the program guide menu screen service based on simple key operation while watching satellite broadcasts, or select viewing or switching of desired specific channels.

However, as described above, the conventional method of guiding only channel information and program information of each channel on the menu screen in the form of a character is insufficient to satisfy a user's desire for providing more various types of information. Therefore, in recent years, the need for new service techniques for providing a wider variety of services, rather than simply providing a program guide service, has emerged in reality.

For example, satellite broadcasting can be used to realize various kinds of information services using pictures, etc., in the form of textual information services, or through various commercial advertisements on the Internet. If the receiver can provide a specific advertisement image along with the program guide information on the menu screen displayed on the monitor whenever the user requests the guide of the broadcast program, the program guide service can be diversified as well as a natural and effective advertisement effect. This could allow stations to increase their ad revenues.

Accordingly, the present invention has been made in view of the above, and when the satellite broadcasting receiver provides a program guide service to the user, the text program content information and the specific still picture advertisements assigned to each channel are combined into one menu screen. An object of the present invention is to provide an improved channel information display method in a satellite broadcasting receiver capable of providing a guide service on a monitor.

Another object of the present invention is to provide a program guide service to the user in a satellite broadcasting receiver, the combination of the program content information in the form of a figure or a picture and a specific still image advertisement of each channel into a single menu screen on the monitor An improved method of displaying channel information in a satellite broadcasting receiver that can be provided is provided.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

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

1 is a block diagram of a satellite broadcasting reception system suitable for applying a method of providing channel information of each broadcast as a menu screen according to the present invention.

As shown in the figure, the satellite broadcasting receiving system includes a tuner and a demodulation block 102, an MPEG decoding block 104, a video encoding block 106, a control block 108, a memory block 110, and a menu generation block. 112 and image composition block 114.

First, in order to provide the user with improved channel information according to the present invention, advertisement packets carrying a plurality of still image advertisement video data corresponding to each channel may be provided on a transport stream received by the satellite broadcasting reception system through a satellite reception antenna. Inserted at predetermined intervals, the identifier (PID) information for these advertisement packets are included in the program information packet data having the broadcast program information of each channel, and also included in the program information packet data carrying the broadcast program information as an example. Character program content information as shown in Fig. 3 is shown or, as an example, shape program content information in a figure or picture form is shown as shown in Fig. 4 as part CH11 and CH12.

That is, in the present invention, each channel has a plurality of still picture advertisement images corresponding thereto. Therefore, assuming that there are five still advertisement images for one channel, the program information packet data having broadcast program information of each channel includes five advertisement packet identifiers (PIDs) corresponding to the corresponding channel.

Referring to FIG. 1, in the tuner and demodulation block 102, when the satellite broadcasting reception system is powered on, additional information (ie, channel information, program information, etc.) inserted on a transport stream received through an antenna is extracted. That is, channel information packet data having program combination table (PAT) information of N-bit program identifier (PID) information representing a broadcast program number of each channel, and N-bit meaning audio, video, text, etc. of a specific channel. The program information packet data having the program map table (PMT) information of the program identifier (PID) information is extracted, and the transport stream is processed through the process of converting the extracted packet data into intermediate frequency, demodulation and error correction. And then to the control block 108 described below via line L12.

At this time, the channel information packet data and the program information packet data extracted from the transport stream and provided to the control block 108 through the line L12 are selected from the transport stream received through the satellite channel when a specific channel desired by the user is selected. It is used to tune a specific channel, and is also used as actual content information of a menu screen when a user is required to provide (i.e., display) a plurality of channel information and broadcast program information of each channel.

Further, in the tuner and demodulation block 102, a user in a broadcast signal received through a broadcast signal receiver (i.e., a satellite reception antenna), not shown, based on a tuning control signal provided from the control block 108 through a line L11. Tunes the selected broadcast channel and restores the tuned broadcast channel signal to the transport stream through the process of converting to the intermediate frequency, demodulation, and error correction, and so on. Provided to the MPEG decoding block 104.

Further, in tuner and demodulation block 102, an advertisement packet extraction signal provided from control block 108 via line L11, i.e., an advertisement packet identifier (PID), when the user requests a program guide service while the user is watching satellite television. ) Extracts the advertisement packets carrying the still image advertisement image data inserted on the transport stream at predetermined time intervals based on the information, and restores the original advertisement signals. The reconstructed advertisement image data are decoded through the line L13. Is provided. That is, there are a plurality of advertisement video packets preset for each channel. The tuner and demodulation block 102 extract and restore the plurality of advertisement video packets sequentially.

On the other hand, the control block 108, for example, includes a microprocessor for performing overall operation control of the receiving system, when the user broadcast channel selection signal is input from the outside generates a corresponding tuning control signal to the line L11 To the above-described tuner and demodulation block 102, and when program guide data (i.e., channel information and program information of each channel) is provided from the tuner and demodulation block 102 via line L12, The data is sequentially stored in predetermined areas of the block 110.

In addition, the control block 108 is stored in the memory block 110 so that when the broadcast channel menu service request signal is input from the outside, the tuner and the demodulation block 102 can extract advertisement packet data corresponding to the selected specific channel. The advertisement packet identifier (PID) information in the program information of the pre-stored specific channel is extracted and transmitted to the tuner and the demodulation block 102 through the line L11. Here, the selected specific channel may be a channel currently being viewed, a channel arbitrarily selected by the user among a plurality of channels, and may be a channel in which a cursor that is movable up, down, left and right according to a user's key operation is located. have.

Further, when the broadcast channel menu service request signal is input from the outside, the control block 108 extracts the channel information data previously stored in the predetermined area of the memory block 110 and the program content information data of each channel, respectively, to draw the line L17. A screen configuration control signal generated on the line L19 to provide a menu generation block 112 and to mix the extracted still image advertisement image and the program guide menu with each other to form a menu screen. As the control signal, for example, a logic signal having a high or low level can be used.

On the other hand, in the MPEG decoding block 104, the spatial and spatial correlation of the compressed coded audio signal and the video signal, for example, the video signal, of the selected broadcast channel provided from the above-described tuner and demodulation block 102 through the line L13. The compressed and encoded video signal is restored to the original signal before encoding using a decoding technique such as variable length decoding, inverse DCT, inverse quantization, motion compensation, and the like. The commercial video signal is restored to the original signal before encoding, and the digital broadcast video signal or the still picture commercial video signal reconstructed is provided to the next video encoding block 106 through the line L15, and the reconstructed audio signal is not shown. Audio signal processor.

In addition, the video encoding block 106 converts the selected digital broadcast video signal or the still and commercial video signal provided in the MPEG decoding block 104 described above into an NTSC or PAL analog video signal, and then through the image synthesis block (line L16). 114).

At this time, the video encoding block 106 stores a plurality of still picture advertisement video signals set for one channel in its own memory, for continuous circular display at intervals of several seconds. That is, as an example, assuming that there are five still image advertisement images allocated to CH11, in the video encoding block 106, five advertisement images are displayed together with text program content information or shape program content information (eg, 1 second). , 2 seconds, etc.) are automatically transferred to the display side to be displayed on the menu screen while automatically switching at intervals.

On the other hand, in the menu generating block 112, when there is a service request signal, the initial menu screen data using the graphic of the channel information data and the program content information data of each channel provided from the above-described control block 108 via the line L17. (I.e., menu screen data occupying approximately the entire monitor), and converts the generated initial menu screen data into an NTSC or PAL analog signal and provides it to the image synthesizing block 114 via line L18.

On the other hand, the image synthesizing block 114 selects the selected (or tuned) analog satellite broadcasting signal on the line L16 based on the screen configuration control signal having a high or low level provided from the control block 108 via the line L19. The menu screen, which is not shown in the drawing, or mixed with the still picture advertisement video signal on the line L16 and the initial menu screen data on the line L18, is transferred to the display side, which is not shown.

That is, when the user requests the program guide service, the image synthesizing block 114 mixes the still image advertisement video signal of the corresponding channel provided through the line L16 with the initial menu screen data provided through the L18 to form one complete menu screen. And the generated menu screen to the display side. Therefore, on the monitor on the display side, which is not shown, as shown in FIG. 3 as an example, a menu screen in which a menu consisting of text program content information and a still image advertisement image corresponding to a specific channel is displayed is displayed, or as an example. As part (CH11, CH12) is shown in Fig. 4, a menu of shape program content information having shapes such as figures and pictures (that is, an image that may mean a corresponding program) and a still picture advertisement corresponding to a specific channel. The menu screen with the mixed images will be displayed.

Next, a process of performing the channel information display method according to the present invention based on the satellite broadcasting reception system having the above-described configuration will be described in detail with reference to FIGS. 1 to 4.

2 is a flowchart illustrating a process of providing a menu screen including channel information and advertisements to a monitor in a satellite broadcasting receiver according to a preferred embodiment of the present invention.

First, in order to implement the improved channel information display according to the present invention, the base station transmitting the satellite broadcasting signal inserts and transmits a plurality of still image advertisement image data for program guide service for each channel. At this time, as an example, when there are five still advertisement images for one channel, the program information packet data having broadcast program information of each channel includes five advertisement packet identifiers (PIDs) corresponding to the corresponding channel.

Referring to FIG. 2, when a user is watching satellite television in a state where program guide packet data, that is, channel information data and program guide information data for each channel are previously stored in the memory block 110 of FIG. 1 (step 202) It is checked whether there is a program menu guide service request (step 204).

In this case, the program content information received and stored in the memory block 110 may be character program content information, as shown in FIG. 3, and as shown in FIG. It may also be shape program content information (ie, an image that may mean a corresponding program).

As a result of the check in the step 204, if it is determined that there is a request for program menu guidance service from the outside, the control block 108 of FIG. 1 searches for program information data previously stored in the memory block 110 and selects a selected channel. The first delimiter (PID) of the corresponding plurality of advertisement packet data is withdrawn and the retrieved first corresponding advertisement packet delimiter (PID) is passed to the tuner and demodulation block 102 via line L11 (step 206).

In this case, the selected specific channel may be a channel currently being viewed, a channel arbitrarily selected by a user among a plurality of channels, and may be a channel in which a cursor that is movable up, down, left and right according to a user's key operation is located. .

Next, the tuner and demodulation block 102 extracts only the corresponding advertisement packet of the selection channel on the received packet stream based on the first corresponding advertisement packet identifier (PID) information of the selection channel provided from the control block 108, Demodulation and error correction are performed on the extracted corresponding advertisement packet data to switch to the encoded transport stream. At this time, the tuner and demodulation block 102 temporarily stops tuning of the channel currently being viewed.

Then, the transport stream for the still-advertised commercial video converted as described above is restored to the original signal before encoding through the MPEG decoding block 104 and the video encoding block 106, and then converted into an NTSC or PAL analog video signal and then the video. It is stored in its own memory of encoding block 106 (step 208).

Meanwhile, the control block 108 extracts the program guide information previously stored in the memory block 110, that is, the channel information and the program information, simultaneously with the extraction of the first corresponding advertisement packet for the selected channel as described above, and through the line L17. The menu generating block 112 converts the channel information and the program content information into the initial menu screen data (that is, the menu screen data occupying the entire monitor) by using a graphic. In step 210, the generated initial menu screen data is converted into an NTSC or PAL analog signal.

In this case, each program content information in the channel includes a variety of information such as the title, program type, rating, start time, broadcast time, pay-for-air broadcasting, etc. Information about each program title is a character information or It can include text + shape information.

Next, in step 212, the corresponding still picture advertisement video signal for the selected channel extracted and reconstructed on the transport packet stream and the generated initial menu screen data are mixed and then provided on the monitor on the display side. Thus, on the monitor, as shown in FIG. 3 as an example, a menu screen in which the text program content information and the still image advertisement image of the selected channel is mixed is displayed, or only a part (CH11, CH12) is shown in FIG. 4 as an example. As shown, a menu screen in which the shape program content information and the still image advertisement image of the selected channel is mixed will be displayed (step 214).

Meanwhile, according to the present invention, generating a menu screen by mixing the corresponding advertisement video of the selected channel extracted from the transport packet stream and the initial menu screen data, for example, is horizontal for each of the advertisement image and the initial screen data. This can be achieved by performing 2: 1 subsampling per line and sequentially switching the outputs of the two signals through a control pulse that divides one horizontal line into two.

Of course, by adjusting the sampling ratio of the corresponding advertisement image of the selected channel and the sampling ratio of the initial menu screen data, the program content information portion displayed on the monitor may be larger or the corresponding advertisement image portion may be enlarged. That is, the size on the menu screen can be adjusted by setting the sampling ratio of the initial menu screen data to 3: 1, the sampling ratio of the corresponding advertisement video of the selected channel to 3: 2, or the respective sampling ratios to the opposite.

In addition, unlike the above, if the monitor is equipped with two scanning devices, the screen is divided into two, and each of the horizontal lines for each of the advertisement image and the initial screen data is 2: 1 subsampling, and then a separate signal processing is performed. It may be realized by scanning two signals transmitted to each scanning device through a path on each divided screen.

Next, in step 216, it is checked whether or not the present display time t for the still picture advertising image in the menu screen on the monitor has reached a preset time L. This time L is, for example, 1 second, It can be set to 2 seconds or the like.

If the check result in step 216 determines that the still picture advertisement image currently being displayed on the menu screen is displayed for a predetermined time, the control block 108 displays the number of still image advertisement images displayed so far for the selected channel. It is checked whether or not P has reached the preset still image number m for the channel (step 218).

On the other hand, if it is determined that P = m is not the result of the check in step 218, that is, five different still image advertisement images are allocated to the selected channel, all five still image advertisement images are not displayed so far. If not, the process returns to step 206 described above and repeats the subsequent process, whereby the display of the next still picture advertisement image will be executed.

Next, as described above, when the menu screen in which the character program content information or the shape program content information and the corresponding still picture advertisement image of the selected channel is displayed on the monitor in accordance with the program menu screen service request from the user, control is performed. In block 108, it is checked whether the user selects another channel, for example switching the cursor located on the currently selected channel (eg CH11) to another channel (eg CH12) (step 220). .

As a result of the check in step 218, if it is determined by the user that another channel is selected, the process returns to step 206 described above and repeats the subsequent process, and the predetermined time (e.g., If it is determined that no other channel is selected within 8 seconds, 10 seconds, etc., the process proceeds to step 222 (step 222). That is, in the present invention, five still advertisement images allocated to the selected channel are repeatedly displayed for a predetermined time period through the repetitive processing of steps 206 to 220.

Therefore, when it is determined that there is no selection of another channel, in step 224, the menu screen currently displayed on the monitor is turned off, and the satellite broadcasting reception system is switched to the viewing mode (step 226). As a result, the broadcast program of the channel that was originally watched will be displayed on the monitor.

That is, as can be seen from the above, in the present invention, assuming that five still picture advertisement images are allocated to one channel, the entire menu screen is displayed together with the text or shape program content information at the service request of the program menu screen. The five still image advertisement images which are comprised are displayed continuously, switching at intervals of several seconds.

As described above, whenever the user requests the guidance of a broadcast program in the satellite broadcasting receiver, a plurality of still image advertisement images assigned to the selected channel together with the text program content information or the shape program content information on the menu screen displayed on the monitor. By automatically switching to every few seconds, it is possible to obtain a natural and effective advertising effect as well as diversification of the program guide service.

Improved method of displaying channel information at the receiver. The method of claim 1, wherein the fifth process comprises: subsampling the reconstructed corresponding advertisement video data and the horizontal line data of the generated initial menu screen data at a predetermined predetermined sampling ratio by using a sampling technique. And displaying the entire menu screen by mixing the two sampled data. The method of claim 1, wherein the monitor has two injection devices, The fifth process divides the screen of the monitor into two, and subsamples the horizontal line data of the restored corresponding advertisement video data and the generated initial menu screen data using a sampling technique at a sampling ratio of 2: 1. And displaying the entire menu screen on the monitor by respectively scanning the two subsampled data on the divided screens through respective corresponding scanning devices. Receive a program guide packet including N-byte channel information packets of channel information transmitted from satellites and N-byte program information packets of program content information of each channel, and N-byte program service data packets of broadcast program data. Restores to the transport stream through demodulation and error correction, stores the restored program guide packet data in a memory area, tunes to a specific channel based on the stored program guide data, and services a program guide menu on the monitor. In the method for displaying channel information in the broadcast receiving system, The program guide packet includes a plurality of pre-assigned still picture advertisement picture data packets corresponding to each channel, and the N-byte program information packet includes shape program title information as a figure or picture and a plurality of preset still picture advertisement pictures. Contains delimiter information for the data packet, The method is: A first step of checking whether there is a program menu guidance service request according to a user's operation when the satellite broadcasting reception system is in a viewing mode while the program guide packet data is received and pre-stored in the memory area; A second step of searching for the memory area and retrieving one of identifier information for a plurality of corresponding still picture advertisement packets of a selected channel when the program menu guide service request is requested; Extract one of a plurality of pre-assigned corresponding still picture advertisement packets of the selected channel on the transport packet stream from the satellite based on the retrieved corresponding advertisement packet identifier information, and display the extracted corresponding still picture advertisement image data; Restoring the signal to a memory and storing the same in a memory; A fourth step of searching for the memory area to extract channel information and program content information and to generate the extracted channel information and program content information as displayable initial menu screen data using a graphic; In response to a screen configuration control signal according to the program menu guide service request, by mixing the restored corresponding still image advertisement image data and the generated initial menu screen data, the shape program title and content information area in a figure or a picture; A fifth step of generating a whole menu screen including a still image advertisement image area and displaying the same on a monitor; A sixth step of displaying the entire menu screen for a predetermined time period and then checking whether all of the plurality of still picture advertisement images previously allocated to the selected channel are displayed; As a result of the check in the sixth step, if it is determined that all of the previously allocated still picture advertisement images are not displayed, the second and sixth steps are repeatedly performed and the next still picture advertisement image is assigned to the selected channel. A seventh process of configuring and displaying the advertisement image area of the entire menu screen; A check for checking whether another channel selection signal according to a user's operation is input from the outside within a predetermined predetermined time during the display of the entire menu screen through sequential switching of the plurality of pre-allocated advertisement images of the selection channel. 8 courses; When the other channel selection signal is input within the predetermined time period, the second to eighth steps are repeated to generate a new whole menu screen corresponding to the selected other channel and display the same on the monitor. process; And If there is no input of the other channel selection signal within the predetermined time period, the satellite broadcast comprising a tenth step of turning off the full menu screen or a new full menu screen being displayed and automatically switching the satellite broadcasting reception system to a viewing mode. Improved method of displaying channel information at the receiver.
