Description

Improved Channel Information and Audio Service Method of Satellite Broadcast Receiver

The present invention relates to a satellite broadcasting receiver, and more particularly, various types of menu screen guide information, such as channel information received through satellite channels and broadcast program information of each channel, may be provided for a specific advertisement or promotional image of a specific broadcast program and the corresponding. The present invention relates to an improved channel information and audio service method of a satellite broadcasting receiver suitable for providing a user with an audio signal.

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. By using the graphical tool prepared for withdrawal, a menu screen in the form of letters as shown in FIG. 7 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 advertising video and corresponding audio signal with text program guide information, or a broadcast promotional video and corresponding audio signal for a broadcast program selected by the user (or the cursor is located) on the menu screen, In addition, diversification of program guidance services, as well as natural and effective advertising effects can be achieved, which will allow each broadcasting station to increase the 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 advertisement image mixed with the channel guide menu information and the corresponding audio signal or channel guide menu information and An object of the present invention is to provide an improved channel information and audio service method of a satellite broadcasting receiver capable of serving a broadcast promotional image of a specific mixed broadcast program and an audio signal corresponding thereto.

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 for displaying channel information in a satellite broadcasting receiving system serving a program guide menu on a monitor, wherein the program guide packet includes a pre-allocated advertisement data packet corresponding to each channel and an advertisement audio data packet corresponding thereto, and each channel. Assigned to each of my broadcasts A song promotion data packet and corresponding broadcast promotion audio data packets, wherein the N-byte program information packet includes character program title information, advertisement data packet identifier information, advertisement audio data packet identifier information, broadcast promotion data packet identifier information, and A broadcast promotion audio data packet identifier information, the method comprising: a program menu guide service according to a user operation when the phase broadcast receiving system is in a viewing mode with the program guide packet data received and stored in the memory area in advance; A first step of checking whether there is a request; When the program menu guide service request is requested, the pre-allocated advertisement packet of the selection channel on the transport packet stream from the satellite based on the advertisement packet identifier information of the selection channel and the corresponding advertisement audio packet identifier information stored in the memory area. And a second step of extracting a corresponding advertisement audio packet and restoring the extracted advertisement image data and the advertisement audio data into a signal output through a monitor and a speaker, respectively. By converting the channel information and program content information drawn from the memory area into displayable initial menu screen data using graphics, in response to a screen configuration control signal, the restored advertisement image data and the initial menu screen data are mixed. A third step of constructing an entire menu screen and outputting the restored advertisement audio signal to the speaker while simultaneously displaying the configured entire menu screen on the monitor; A fourth step of checking whether a key signal for changing a channel according to a user's operation or selecting a broadcast program in the selected channel is input when the entire menu screen is displayed for a predetermined time; When the channel change signal is input, the second process and the third process are repeated to generate a new whole menu screen corresponding to the changed channel, display the same on the monitor, and simultaneously display the corresponding advertisement audio signal. A fifth process of outputting to a speaker; As a result of the check in the fourth process, when the selection key signal of the broadcast program is input, the broadcast transmission packet identifier information and the broadcast promotion audio packet identifier information of the selected broadcast program stored in the memory area are extracted from the received transport stream. A sixth step of restoring a broadcast promotional video data and a broadcast promotional audio data of a selected broadcast program into signals output through the monitor and the speaker, respectively; The restored broadcast promotional image data and the initial menu screen data are mixed to form another new full menu screen, and the configured new full menu screen is displayed on the monitor and the restored broadcast promotional audio signal is recalled. A seventh process of outputting to the speaker; An eighth step of checking whether a key signal for changing to another channel or selecting another broadcast program in the selected channel is input when the other new full menu screen is displayed for a predetermined time; As a result of the check in the eighth process, when the change key signal to the other channel is input, the second process and the third process are repeated, and when the change key signal to the other broadcast program is input, the sixth process and A ninth process of repeating the eighth process; And turning off the full menu screen, the new full menu screen, or another new full menu screen being displayed if there is no input for the change to another channel or a change key signal to another broadcast program within the predetermined time.

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 satellite suitable for applying a method for providing a menu screen by mixing channel information of each broadcast and an advertisement image or a broadcast promotion image and serving an audio signal corresponding to the corresponding advertisement image or broadcast promotion image according to the present invention. A block diagram of a broadcast receiving system is shown.

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, an audio processing block 108, a control block 110, and a memory block. 112, a menu generation block 114, and an image composition block 116.

First, in order to provide the user with improved channel information according to the present invention, an advertisement packet carrying advertisement image data corresponding to each channel and a corresponding advertisement on a transport stream received by the satellite broadcasting receiving system through a satellite receiving antenna. Audio packets are inserted at predetermined intervals, and broadcast broadcast packets carrying broadcast promotional video data corresponding to each broadcast program in each channel and broadcast broadcast audio packets corresponding thereto are also included. The identifier (PID) information for the packet, the broadcast promotion packet, and the broadcast promotion audio packets are included in program information packet data having broadcast program information of each channel. In addition, the program information packet data carrying the broadcast program information includes character program content information as shown in Figs.

Here, the advertisement image data allocated to each channel may be a still image composed of a plurality of preset still images or a moving picture which is broadcast for several seconds. In addition, the broadcast promotional video data allocated to each broadcast program may be one still image (that is, a poster) that may well mean the broadcast program, and may be used for several seconds (for example, to represent the broadcast program well). 10 seconds, 15 seconds, etc.).

Therefore, the advertisement audio packet and the broadcast promotion audio packet carry audio data that may correspond to the image included in the advertisement packet and the broadcast promotion packet.

In this case, assuming that there are five advertisement images allocated to 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 and five advertisement audio corresponding thereto. The packet delimiter (PID) will be included.

Meanwhile, according to the present invention, the advertisement image and the broadcast promotion image including the entire menu screen together with the channel menu information are subsampled and divided into two through the sampling technique as shown in FIGS. 3 and 5 as an example. (Still or moving picture) or, as an example, as shown in FIGS. 4 and 6, it may be a full-screen semi-transparent broadcast promotion video (still or moving picture) that is semi-overlapping over the entire channel menu information.

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, the tuner and demodulation block 102 select channel corresponding advertisement packet and corresponding advertisement audio packet identifier provided from the control block 110 via line L11 when the user requests a program guide service while the user is watching satellite television. Corresponding advertisement packets and advertisement audio packets of the selected channel inserted at predetermined time intervals on the transport stream based on the (PID) information, the broadcast promotion packet of the selected broadcast program and the broadcast promotion audio packet identifier (PID) information of the selected broadcast program, The broadcast advertisement packet and the broadcast promotion audio packet of the selected broadcast program are extracted and restored to the original signal. The restored advertisement image and audio data and the broadcast promotion image and audio data are provided to the MPEG decoding block 104 through the line L13. do.

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.

In addition, when the broadcast channel menu service request signal is input from the outside, the control block 110 corresponds to the advertisement packet and the advertisement audio packet data corresponding to the specific channel selected by the tuner and the demodulation block 102, and the corresponding specific broadcast program. The advertisement packet identifier (PID) and the advertisement audio packet identifier (PID) in the program information of a specific channel (i.e., a selected channel) previously stored in the memory block 112 so as to extract the broadcast promotion packet data and the broadcast promotion audio packet data. The information, the broadcast promotion packet, and the broadcast promotion audio packet identifier (PID) information are extracted and transmitted to the tuner and demodulation block 102 via 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 110 extracts the channel information data pre-stored in the predetermined area of the memory block 112 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 the menu generation block 114 and to mix the text data for advertisement or text data for broadcast promotion with the channel program guide menu to form a whole menu screen. As the generated screen configuration 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, on the basis of the control signal provided from the control block 110, the compression-coded video 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 audio signal, for example, the video signal, 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, and motion compensation, Here, the reconstructed digital broadcast video signal is provided to the next video encoding block 106 via line L14, and the reconstructed digital audio signal is provided to the audio processing block 108 via line L15.

Further, in the MPEG decoding block 104, when there is a menu guide service request according to the present invention, the encoded advertisement video and the broadcast promotional video provided from the tuner and the demodulation block 102 through the line L13 as the original signal before encoding. It is restored and provided to the video encoding block 106 through the line L14.

Accordingly, in the video encoding block 106, the selected digital broadcast video signal provided in the MPEG decoding block 104 described above, the advertisement video (still or moving picture) of the selected channel, or the broadcast promotional video (still or moving picture) of the selected broadcast program are displayed. It is converted into an NTSC or PAL analog video signal and then provided to the image synthesis block 116 via line L16.

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 L17, are initialized using a graphic. It generates the menu screen data (i.e., menu screen data occupying approximately the entire monitor), converts the generated initial menu screen data into an NTSC or PAL analog signal, and provides it to the image synthesizing block 116 via line L18.

On the other hand, the image synthesizing block 116 receives 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 110 through the line L19. The menu screen, which is not shown in the drawing, or which mixes text data for advertisement or broadcast promotional text data on the line L16 and initial menu screen data on the line L18, is transferred to the display side, not shown.

At this time, the advertisement image and the broadcast promotional image displayed on the entire menu screen displayed with the channel guide information, for example, as shown in Figs. Generating the entire menu screen by mixing the channel menu information, for example, performs 2: 1 subsampling in each horizontal line unit for each of the advertisement image or the broadcast promotion image and the channel menu information, and divides one horizontal line into two. It can be realized by sequentially switching the output of the two signals (advertisement video (or broadcast promotional video) and channel menu information) through a control pulse.

Of course, by adjusting the sampling ratio of the corresponding advertisement image or the broadcast promotion image and the sampling ratio of the channel menu information, the portion of the channel menu information displayed on the monitor may be made larger or the corresponding advertisement image or the broadcast promotion image portion may be enlarged. will be. That is, the size on the entire menu screen can be adjusted by setting the sampling ratio of the channel menu information to 3: 1, the sampling ratio of the corresponding advertisement video or the broadcast promotion image to 3: 2, or the opposite sampling ratios.

In addition, unlike the above, if the monitor is provided with two scanning devices, the screen is divided into two, and 2: 1 subsampling is performed in each horizontal line unit for each of the advertisement image (or broadcast promotion image) and the channel menu information. Then, it may be realized by scanning two signals (advertising image (or broadcast promotion image) and channel menu information) respectively transmitted to each scanning apparatus through separate signal processing paths on each divided screen.

Unlike the above, when the advertisement image and the broadcast promotion image displayed on the entire menu screen displayed together with the channel guide information are configured, for example, as shown in FIGS. 4 and 6, through the line L16 Full-over semi-transparent advertising video or full-screen semi-transparent broadcast video by overlapping full-screen semi-transparent advertising video or full-screen translucent broadcast-promotion video over the channel menu information data provided through line L18. You can create a screen.

Next, a process of providing channel information and the corresponding audio service 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 6.

FIG. 2 is a satellite broadcasting receiver which provides a menu screen by mixing channel information of each broadcast and an advertisement image or a broadcast promotion image in a satellite broadcast receiver, and simultaneously provides an audio signal corresponding to the corresponding advertisement image or broadcast promotion image. It is a flowchart showing the process of doing so.

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 in FIGS. 3 to 6.

As a result of the check in the step 204, if it is determined that the user requests a program menu guide service, the control block 110 of FIG. 1 searches for program information data previously stored in the memory block 112, A delimiter (PID) of the corresponding advertisement packet and a delimiter (PID) of the advertisement audio packet are fetched, and the extracted advertisement packet identifier (PID) and the identifier of the advertisement audio packet (PID) are connected through the line L11 to the tuner and the demodulation block ( 102).

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. .

Accordingly, in the tuner and demodulation block 102, the corresponding advertisement of the selection channel on the packet stream received based on the advertisement packet identifier (PID) of the selection channel and the identifier (PID) information of the advertisement audio packet provided from the control block 110. Only the packet and the advertisement audio packet are extracted, and the extracted advertisement packet and the advertisement audio packet data are demodulated, error corrected, and the like to be converted into an 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 advertising text data converted as described above is restored to the original signal before encoding through the video encoding block 106, wherein the restored advertising text data is transmitted through the image synthesis block (line L16). 116).

Meanwhile, the control block 110 extracts the program guide information previously stored in the memory block 112, that is, the channel information and the program information, simultaneously with the extraction of the advertisement packet for the selected channel as described above, and the menu generation block through the line L17. The menu generating block 114 converts the channel information and the program content information into initial menu screen data (that is, menu screen data occupying approximately the entire monitor) using graphics, and generates the generated information. Converted initial menu screen data into an NTSC or PAL analog signal and then provided to the image synthesis block 116 via line L18.

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 L19, the advertisement menu on the line L16 and the initial menu screen data on the line L18 are mixed to make the entire menu screen. Configure step 206.

In this case, the advertisement image generated on the entire menu screen may be, for example, an image (stilled or animated) divided into channel menu information, as shown in FIG. 3, and as shown in FIG. 4 as an example. For example, the image may be a semi-transparent image overlapping over-transparently throughout the channel menu information.

In addition, the advertisement image generated on the entire menu screen may be a still image advertisement in which a plurality of preset still image advertisements are sequentially switched at predetermined time intervals (for example, 2 seconds, 4 seconds, etc.). It may be a fairy tale advertisement that is shown for a few seconds.

Meanwhile, at the same time as the above-described processing of the advertisement image, the audio processing block 108 converts the reconstructed digital advertisement audio signal provided from the MPEG decoding block 104 through the line L15 into a substitute analog signal, level amplification, and noise. Signal processing such as removal is performed, and the corresponding advertisement audio signal processed as described above is transferred to a speaker (not shown) (step 208).

Then, the entire menu screen in which the advertising image output from the image synthesizing block 116 and the channel menu information are mixed is displayed on the monitor and the corresponding advertising audio signal is transmitted from the audio processing block 108 to the speaker side. Simultaneously with the display of the menu screen with the advertisement image, the corresponding advertisement audio is output through the speaker (step 210).

Next, as described above, in response to a program menu screen service request from the user, the entire menu screen in which the character program content information (i.e., channel menu information) and the advertisement image of the selected channel are mixed is displayed on the monitor and the speaker is turned on. When the advertisement audio corresponding to the advertisement video is output through the control block 110, the control block 110 allows the user to change the channel or select a specific broadcast program of the selected channel, for example, a cursor located in the currently selected channel (eg, CH11). Switch to another channel (e.g., CH12) (step 212) or select a particular broadcast program in the selected channel (e.g., a diagonal Jurassic Park program is selected in CH11 of FIGS. 3 and 4). It is checked whether or not (step 214).

As a result of the check in step 212, 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 the check in step 216 For a predetermined time (eg, 5 seconds, 8 seconds, etc.), that is, in step 216, it is checked whether a channel is changed or a broadcast program is selected in a selected channel within a predetermined time. If it is determined that there is no channel change or selection of the broadcast program of the selected channel, the process proceeds to step 228 to be described later, in which the entire menu screen currently displayed (that is, the entire menu screen mixed with the channel menu information and the advertisement image) is turned off. At the same time, the speaker output is turned off, and the satellite broadcasting receiving system is automatically switched to viewing mode.

That is, if there is no change to another channel or a broadcast program selected in the selected channel after the user's request for program guidance, the predetermined time when the entire menu screen in which the advertisement image allocated to the selected channel and the channel menu information are mixed is preset on the monitor. The satellite broadcasting reception system turns off the menu screen and automatically switches to the viewing mode after a predetermined time elapses.

On the other hand, as a result of the check in step 214, it is determined that the user selected any one of a plurality of broadcast programs in the currently selected channel (for example, the Jurassic Park program of CH11 shown in FIGS. 3 and 4). If so, processing proceeds to step 218.

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.

Next, in step 218, when one of the plurality of broadcast programs in the current selection channel is selected by the user (e.g., the Jurassic Park program of CH11 shown in Figs. 3 and 4), the memory block is selected. The program guide information data of the selected channel pre-stored in the 110 is searched for, and the broadcast promotion packet identifier (PID) of the selected broadcast program is extracted and transmitted to the tuner and the demodulation block 102 through the line L11.

At this time, the broadcast promotion packet data of the selected broadcast program extracted from the tuner and the demodulation block 102 is, for example, as shown in Figs. 5 and 6, the Jurassic Park in which the broadcast program selected by the user is filled with diagonal lines in the same diagram. Assuming a program, it may be data of a moving picture broadcasting promotional image (that is, moving pictures for several seconds that may well represent characteristics of the corresponding program) for several seconds corresponding to the selected broadcast program.

Therefore, in steps 218 and 220, as in the above-described steps 206 and 208, the entire menu screen is constructed by mixing the broadcast promotion video restored with the original signal with the channel menu information to omit the illustration. And a signal processing such as converting the restored audio signal into an analog signal and outputting the same to the speaker.

As a result, the entire menu screen mixed with the broadcast promotional image is displayed on the monitor and the corresponding advertisement audio is output through the speaker (step 222).

In this case, the broadcast promotional image generated on the entire menu screen may be an image (still or moving picture) divided into channel menu information and divided into two, as shown in FIG. 5 as an example. Likewise, it may be a semi-transparent image overlapping semi-transparently over the channel menu information. In addition, the broadcast promotional video generated on the entire menu screen may be a still picture advertisement (poster) or may be a moving picture advertisement that is screened for a predetermined number of seconds.

Next, in step 224, as described above, when the program menu screen service is provided, the character program content information (i.e., channel menu information) of each channel and the broadcast promotion image (still image) of the selected broadcast program according to the user's broadcast program selection. Or a moving picture) is displayed on the monitor and the corresponding broadcast promotion audio signal is being output through the speaker, and it is checked whether another selection key signal is input, that is, the user selects another channel or selection. It is checked whether to select another broadcast program in the channel, and the input check of this other selection key signal is automatically performed for a predetermined time (for example, 5 seconds, 8 seconds, etc.) (step 226).

Here, switching to another channel or selecting another broadcast program may be realized, for example, by moving the cursor on the menu screen to the target channel or the position of the 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 224, the processing proceeds to a corresponding step, i.e., when a key signal for channel switching is input, the processing is described above. The process returns to step 206 to repeat the process thereafter, and when a selection key signal for another broadcast program in the current selection channel is input, the process returns to step 218 described above. The same process is repeated.

On the other hand, if the result of the check in step 226 determines that another channel or another broadcast program in the selected channel is not selected within a predetermined time, the process proceeds to step 228, and in step 228 Turns off the entire menu screen currently being displayed on the screen, cuts off the output of the spur and automatically switches the satellite reception system to 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, the satellite broadcasting receiver displays a still image or moving picture advertisement image previously assigned to a selected channel along with text program content information of each channel on the entire menu screen displayed on the monitor. Pre-assigned still picture of the selected broadcast program that can be configured and output the corresponding advertisement audio signal through the speaker, and can represent the selected specific broadcast program when the user selects a specific broadcast program in the selected channel on the menu screen. In addition, by providing the video contents of the entire menu screen with the information of the contents of the character program of each channel, and outputting the corresponding advertising audio signal through the spaker, the program guide service as well as the natural and effective general Advertising And a promotion (ie, advertisement) effect of each broadcast program.
