Improved Display Method of Channel Information in Satellite Broadcasting Receivers

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

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, as a variety of product advertisements are realized through advertisement sites on the Internet, which has been widely used in recent years, the menu screen displayed on the monitor is displayed on the monitor whenever the user requests the guidance of a broadcast program. If you can provide a specific text advertisement video with text program guide information on the screen, or provide outline text information (i.e., text promotion video) for a broadcast program selected by the user (or the cursor is located) on the menu screen, In addition to the diversification of services, natural and effective advertising effects can be achieved, which may allow each broadcasting station to increase its additional advertising revenue.

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 specific text advertisements assigned to each channel are configured as one menu screen. Display on the monitor, and when selecting a broadcast program for a specific channel on the menu screen, a satellite broadcast receiver capable of displaying the text program content information and the text promotion image of the selected broadcast program into one menu screen and displaying it on the monitor. An object of the present invention is to provide an improved method for displaying channel information in.

In order to achieve the above object, the present invention provides a program guide packet and broadcast program data including an N-byte channel information packet of channel information transmitted from a satellite and an N-byte program information packet of program content information of each channel. Receive the received N bytes of the program service data packet, restore it to the transport stream through demodulation and error correction, store the restored program guide packet data in a memory area, tune to a specific channel based on the stored program guide data, A method of displaying channel information in a satellite broadcasting receiving system serving a program guide menu on a monitor, wherein the program guide packet includes a plurality of pre-allocated text advertisement data packets corresponding to each channel and each broadcast program in each channel. Broadcast text promotional data packets for The N-byte program information packet includes character program title information, delimiter information of a plurality of text advertisement data packets previously assigned to a channel, and delimiter information of a broadcast character promotion data packet previously assigned to each broadcast program. The method may include: a first process of checking whether there is a program menu guide 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 stored in the memory area in advance; ; When the program menu guide service request is made, the memory area is searched to retrieve one of delimiter information for a plurality of corresponding text advertisement packets of a selected channel, and from the satellite based on the extracted corresponding text advertisement packet identifier information. Extracting one of the pre-allocated corresponding text advertisement packets of the selected channel on the transport packet stream of the second channel, and restoring the extracted corresponding text advertisement data into a displayable signal; A third step of retrieving channel information and program content information by searching the memory area, and generating the extracted channel information and program content information as displayable initial menu screen data using a graphic; In response to the screen configuration control signal in response to the program menu guide service request, the restored corresponding text advertisement data and the generated initial menu screen data are mixed to form a text channel information, a program content information area, and a text advertisement area. Generating a menu screen and displaying the menu screen on the monitor; Repeat the steps 2 to 4 until the plurality of text advertisement images previously allocated to the selected channel are displayed to display the next text advertisement image previously allocated to the selected channel. A fifth process of sequentially configuring the display; During the display of the entire menu screen, it is checked whether a key signal for changing to another channel or selecting a broadcast program in the selected channel is input for a predetermined time, and when the change key signal for the other channel is input, A sixth process of repeating the second to fifth processes; As a result of the check in the sixth step, when the selection key signal of the broadcast program is input, the selected broadcast program extracted from the received transport stream by using the broadcast character promotion data packet identifier information of the selected broadcast program stored in the memory area is selected. A seventh step of restoring the broadcast text promotion advertisement data into a displayable signal; The restored text message advertisement data and initial menu screen data including channel information and program content information drawn from the memory area are mixed to form a text program title and content information area and a broadcast letter promotion advertisement area of a selected broadcast program. An eighth step of generating and displaying an entire menu screen; A ninth step of checking whether a key signal is input for changing to another channel or selecting another broadcast program in the selected channel during a predetermined time during the display of the new full menu screen; When the change key signal to the other channel is input as a result of the check in the ninth step, the second to fifth steps are repeated. When the change key signal to the other broadcast program is input, the seventh step and the fifth step are performed. A tenth process of repeating the eighth process; And when there is no input for a change to another channel or a change key signal to another broadcast program within the predetermined time, turn off the full menu screen or the new full menu screen being displayed and watch the satellite broadcasting reception system.

Broadcast text promotion packets, which contain packets and text promotion data for broadcast programs of respective channels, are inserted at predetermined intervals. The identifier (PID) information of the broadcast text promotion packets indicates broadcast program information of each channel. The program information packet data contained in the program information packet data having the program information and carrying the broadcast program information includes, as an example, character program content information as shown by reference numeral B of FIG. 3A.

That is, in the present invention, each channel has a plurality of text advertisement images corresponding to each channel and a broadcast character promotion image corresponding to each broadcast program in each channel. Therefore, assuming that there are five text advertisement images assigned to one channel and one text promotion image assigned to each broadcast program, program information packet data having broadcast program information of each channel corresponds to the corresponding channel. Five text advertisement packet identifiers (PIDs) and one broadcast character promotion packet identifier (PID) will be included.

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. After restoring, the process is provided to the control block 110 described later through the 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 110 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.

In addition, 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 110 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 the tuner and demodulation block 102, a text advertisement packet extraction signal provided from the control block 110 via line L11, i.e., a text advertisement packet delimiter, when the user requests a program guide service while the user is watching satellite television. Based on the (PID) information, the text advertisement packets carrying the text data for text advertisements inserted in the transmission stream at predetermined time intervals are extracted and restored to the original signal, and the user selects a specific broadcast program in the selected channel on the menu screen. The original signal is extracted by extracting the broadcast character promotion packets carrying the text character promotion text data inserted at a predetermined time interval on the transport stream based on the broadcast character promotion packet identifier (PID) information provided from the control block 110 through the line L11. Text ads data and room Character promotion data are provided in the text decoding block 108 through line L14. That is, on the scarlet stream, there are a plurality of text advertisement packets pre-allocated for each channel and one broadcast text promotion packet pre-allocated for each broadcast program. In the tuner and demodulation block 102, the plurality of text advertisement packets are assigned. Extract and restore packets sequentially.

On the other hand, the control block 110, for example, includes a microprocessor that performs 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 a predetermined area of the block 112.

Further, when the broadcast channel menu service request signal is input from the outside, the control block 110 transmits the text advertisement packet data corresponding to the specific channel selected by the tuner and the demodulation block 102 and the broadcast text promotion packet corresponding to the selected broadcast program. In order to extract the data, the text advertisement packet identifier (PID) information of the program information of the specific channel (that is, the selected channel) previously stored in the memory block 112 and the text promotion packet identifier (PID) information of the selected broadcast program are extracted. To the tuner and demodulation block 102 via line L11. 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. .

Here, the broadcast character promotion data for the selected broadcast program is, for example, as shown in reference numerals A of FIGS. 4A to 4D, assuming that the selected broadcast program is a baseball relay program filled with diagonal lines in the same plane. Team ranking, team history, team batting rate, team defense rate, team home run, residual game, etc. for each team that runs the game. , Date of production, outline of content, and so on.

Further, when the broadcast channel menu service request signal is input from the outside, the control block 110 extracts the channel information data previously stored in the predetermined area of the memory block 112 and the program content information data of each channel, respectively, to draw the line L19. A screen configuration control signal provided to the menu generation block 114 through which text data for text advertisement of the selected channel or text data for text promotion of the selected broadcast program and program guide menu are mixed with each other to form a menu screen. A logic signal having a high or low level may be used as the screen configuration control signal generated at L21 and generated at this time.

On the other hand, in the MPEG decoding block 104, on the basis of the control signal provided from the control block 110, the compressed-coded audio signal of the selected broadcast channel provided from the above-described tuner and demodulation block 102 through line L13 and In consideration of the spatiotemporal and spatial correlation of the video signal, for example, the video signal is decompressed to the original signal before encoding by using a decoding technique such as variable length decoding, inverse DCT, inverse quantization, motion compensation, The reconstructed digital broadcast video signal is provided to the next video encoding block 106 via the line L16, and the reconstructed audio signal is provided to the audio signal processor, not shown, via the line L15.

In addition, the video encoding block 106 converts the selected digital broadcast video signal provided in the MPEG decoding block 104 described above into an NTSC or PAL analog video signal and then provides it to the image synthesis block 116 through the line L17.

Next, in text decoding block 108, in response to the broadcast channel menu service request, the test data for the selected text or the selected broadcast program of the selected channel provided from the tuner and demodulation block 102 described above via line L14. Restoring the encoded broadcast character promotion data to the original signal before encoding, that is, the received text advertisement text data and the text promotion text data are long or short based on the frequency of occurrence codes, for example, as is well known in the art. The encoded text data may be decoded into an original signal, and the decoded text advertisement data or broadcast text promotion data may be encoded through a line L18. Provided at 116.

On the other hand, in the menu generation block 114, when there is a broadcast channel menu service request signal, the channel information data and the program content information data of each channel, which are provided from the above-described control block 110 through the line L19, are initialized by using the graphic. Menu screen data (ie, menu screen data occupying approximately the entire monitor) is generated, and the generated initial menu screen data is converted into an NTSC or PAL analog signal and provided to the image synthesis block 116 through the line L20.

Meanwhile, the image synthesizing block 116 receives the selected (or tuned) analog satellite broadcasting signal on the line L17 based on the screen configuration control signal having the high or low level provided from the control block 110 through the line L21. The menu screen which transfers the text data for the text advertisement on the line L18 or the text data for the broadcast character promotion and the initial menu screen data on the line L20 to the display side, not shown, is transferred to the display side, not shown.

That is, in the image synthesizing block 116, when the user requests a program guide service, a text advertisement data or broadcast text promotion data of the corresponding channel provided through the line L18 is mixed with initial menu screen data provided through the L20. Creates a complete menu screen (text menu + text ad or text menu + broadcast promotion ad) and delivers the generated menu screen to the display side. Therefore, on the monitor on the display side, which is not shown, as shown in Figs. 3A to 3D and 4A to 4D, a menu of text program content information and a text advertisement or a specific broadcast program corresponding to a specific channel are shown. A menu screen in which the corresponding broadcast text promotion advertisement is mixed will be displayed.

In this case, the menu screen in which the text menu displayed on the monitor and the text advertisement or the broadcast text promotion advertisement are mixed according to the present invention is, as an example, shown in FIGS. 3A to 3D and 4A to 4D, respectively. Alternatively, the broadcast text advertisement may be set to be positioned at the top, bottom, left, or right of the screen, and the position of the advertisement text may be selected to be adaptively positioned at the top, bottom, left, or right sides according to a user's manipulation. Can be. In FIGS. 3A to 3D and 4A to 4D, each reference numeral A denotes a text advertisement region and a broadcast text promotion advertisement region, and each reference numeral B denotes a menu region of channel information, respectively.

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 3.

FIG. 2 is a flowchart illustrating a process of providing a monitor with a menu screen including channel information, a text advertisement, and channel information and a broadcast text promotion advertisement 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, a base station transmitting a satellite broadcasting signal includes a plurality of text advertising text data for program guide service and broadcast text promotion text data corresponding to each broadcast program for each channel. Insert to send. At this time, as an example, assuming that there are five text advertisement images assigned to one channel and one text promotion advertisement is allocated to each broadcast program, the program information packet data having the broadcast program information of each channel is included in the text advertisement of the corresponding channel. Each of the five advertising packet identifiers (PID) corresponding to each broadcast program information advertising packet identifier (PID) corresponding to each broadcast program will be included.

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 is character program content information, as shown by reference numeral B of FIG. 3.

If it is determined in step 204 that there is a request for program menu guide service from the outside, the control block 110 of FIG. 1 searches for program information data previously stored in the memory block 112 and selects the selected channel. A first delimiter (PID) of the corresponding plurality of text advertisement packet data is fetched, and the retrieved first corresponding text advertisement packet delimiter (PID) is passed to the tuner and demodulation block 102 via line L11.

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. .

Therefore, the tuner and demodulation block 102 extracts only the corresponding text advertisement packet of the selected channel on the received packet stream based on the first corresponding text advertisement packet identifier (PID) information of the selection channel provided from the control block 110. Then, demodulation and error correction are performed on the extracted corresponding text advertisement packet data to convert 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 encoded transport stream for the text data for text advertisements converted as described above is restored to the original signal before encoding through the text decoding block 108, wherein the restored text data for text advertising is synthesized through line L18. It is passed to block 116 (step 206).

Meanwhile, the control block 110 extracts the program guide information pre-stored in the memory block 112, that is, the channel information and the program information, simultaneously with the extraction of the first corresponding text advertisement packet for the selected channel as described above. The menu generation block 114 converts the channel information and program content information into initial menu screen data (ie, menu screen data occupying approximately the entire monitor) using graphics. The generated initial menu screen data is converted into an NTSC or PAL analog signal (step 208).

At this time, each broadcast program content information in the channel includes various information such as title, program type, rating, start time, broadcast time, paid broadcasting or not.

Next, in the image synthesizing block 116, in response to the screen configuration control signal provided from the control block 110 via the line L21, the predetermined text advertisement position or the variable text advertisement position according to the user's selection is determined ( Step 210), on the basis of the determined positional information (blank signal for text advertisement), the text advertisement data on the line L18 and the initial menu screen data on the line L20 are mixed to form the entire menu screen of the text advertisement and the channel information menu. (Step 212).

In this case, when the text advertisement is located at the upper side or the lower side of the entire menu screen, as shown in FIGS. 3A and 3B as an example, the number of channel information displayed as much as the text advertisement occupies will be reduced. For example, as illustrated in FIGS. 3C and 3D, when located at the left side or the right side of the entire menu screen, the number of program information in each channel displayed as much as the text advertisement occupies will be reduced. That is, according to the present invention, when the text advertisement is inserted and provided on the menu screen, the number of channel information or the number of program information in each channel is cut as much as the text advertisement occupies.

However, unlike the above description, the menu screen data is subsampled for each vertical line or horizontal line to secure an area in which a text advertisement is inserted so that the channel information or program information of each channel in the channel information menu area is not cut out. Could be

Thus, on the monitor, as shown in Figs. 3A to 3D, for example, a menu screen in which the character program content information for each channel and the text advertisement for the selected channel will be displayed (step 214).

Next, in step 216, it is checked whether or not the present display time t for the text advertisement image in the menu screen on the monitor has reached a preset time L. The preset time L is, for example, 1 Can be set to seconds, 2 seconds, etc.

If it is determined in step 216 that the text advertisement currently being displayed on the advertisement area B in the menu screen is displayed for a preset time, the control block 110 displays the text advertisement displayed so far for the selected channel. It is checked whether P representing the number of s has reached the number m of text ads previously assigned to 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 text advertisement images are allocated to the selected channel, all five text 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 text advertisement image will be performed.

Next, as described above, when the menu screen in which the text program content information and the corresponding text advertisement of the selected channel are mixed is displayed on the monitor according to the program menu screen service request from the user, the control block 110 displays the user at the control block 110. Selects a specific broadcast program of another channel or a selected channel, for example, switches the cursor located on the currently selected channel (eg CH11) to another channel (eg CH12) (step 220) or within the selected channel. It is checked whether or not a specific broadcast program is selected (e.g., a baseball relay program drawn in diagonal lines in CH12 of Figs. 4A to 4D) (step 222).

As a result of the check in step 220, if it is determined by the user that another channel is selected, the process returns to step 206 described above and repeats the subsequent steps, and further steps 220 and 222. ) Check is performed for a predetermined time period (for example, 5 seconds, 8 seconds, etc.), that is, in step 224, it is checked whether a channel change or a selected program is selected within a predetermined time period. If it is determined that there is no channel change or selection of a broadcast program in the selected channel, the process proceeds to step 238 of FIG. 2B to be described later, in which the currently displayed menu screen is turned off, and the satellite broadcasting receiving system enters the viewing mode. It is switched automatically.

That is, if there is no change to another channel or no broadcast program selection in the selected channel after the user's request for program guidance, a menu screen in which each still image and text program content information assigned to the selected channel is mixed is preset on the monitor. Displayed for a predetermined time, and after a predetermined predetermined time, the satellite broadcast receiving system turns off the menu screen and automatically switches to the viewing mode.

At this time, switching to another channel or selection of another broadcast program may be realized by, for example, moving the cursor on the menu screen to the position of the target channel or target broadcast program to be switched.

On the other hand, as a result of the check in the step 222, the user broadcasts any one of a plurality of broadcast programs in the currently selected channel (e.g., baseball game with a diagonal line in CH12 shown in Figs. 4A to 4D). If it is determined that is selected, then processing proceeds to step 226 of FIG. 2B.

Next, in step 226, when any one of a plurality of broadcast programs in the current selection channel (e.g., baseball relay of Figs. 4A to 4D) is selected by the user, the memory block 112 writes to the memory block 112. The program information data of the selected selection channel is searched and the identifier (PID) of the broadcast character promotion packet packet data of the selected specific broadcast program is extracted and transmitted to the tuner and the demodulation block 102 through the line L11.

Therefore, in steps 226 to 230, as in the above-described steps 206 to 212, a menu screen in which the text program content information and the broadcast text promotion image for the selected broadcast program in the selected channel are mixed. It is then generated and provided on the monitor on the display side. As a result, as shown in Figs. 4A to 4D, on the monitor, a menu screen in which the character program content information and the broadcast character promotion image of the selected broadcast program is mixed will be displayed (step 232).

In this case, the text promotion advertisement of the selected broadcast program displayed on the monitor may be variably displayed through the positioning of the same method as the display technique of the text advertisement described above.

Next, in step 234, as described above, when the program menu screen service is provided, a menu screen in which the text program content information and the broadcast text promotion image of the selected broadcast program are mixed according to the user's broadcast program selection is illustrated in FIGS. As shown in 4d, when being displayed on the monitor, it is checked whether another selection key signal is input, i.e., whether the user selects another channel or another broadcast program in the selection channel. The input check of the other selection key signal is automatically performed for a predetermined time (e.g., 5 seconds, 8 seconds, etc.) (step 236).

At this time, switching to another channel or selection of another broadcast program may be realized by, for example, moving the cursor on the menu screen to the position of the target channel or target broadcast program to be switched.

On the other hand, if it is determined that another selection key signal is input within a predetermined time as a result of the check in step 234, the process proceeds to the corresponding step, i.e., when the key signal for channel switching is input, the process is described above. Returning to step 206 of FIG. 2A and repeating the subsequent process, when the selection key signal for another broadcast program in the current selection channel is inputted, the process returns to step 226 described above. The same process is repeated.

On the other hand, if the result of the check in step 236 determines that another channel or another broadcast program in the selected channel is not selected within a predetermined time, the process proceeds to step 238, and in step 238 the monitor The menu screen currently displayed on the screen (text advertisement + broadcast text promotion advertisement) is turned off, and the satellite broadcasting reception system is switched to the viewing mode. Thus, on the monitor, the broadcast program of the channel that was first watched will be displayed.

As described above, whenever a user requests a guide of a broadcast program in a satellite broadcasting receiver, a plurality of text advertisement images assigned to a selected channel along with text program content information are automatically displayed on the menu screen displayed on the monitor every few seconds. By providing a menu screen on which the text message contents and the text program content information assigned to the selected specific broadcast program are mixed on the monitor when the user selects a specific broadcast program in the selected channel on the menu screen. In addition to the diversification of guidance services, natural and effective general advertisements and promotions (ie, advertisements) of each broadcasting program can be obtained.
