Description

Improved Display Method of Channel Information in Satellite Broadcasting Receivers

The present invention relates to a satellite broadcasting receiver, and more particularly, to display various types of menu screen guide information such as channel information received through a satellite channel and broadcasting program information of each channel, and a general advertisement or a promotional advertisement of a specific program in a selected channel. The present invention relates to an improved method of displaying channel information in a satellite broadcasting receiver suitable for providing to a user.

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 a letter as shown in FIG. 6 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. Whenever the receiver requests the guidance of a broadcast program, the receiver provides a specific advertisement image along with the program guide information on the menu screen displayed on the monitor, or a reference to the broadcast program selected by the user (or the cursor is located) on the menu screen. If it is possible to provide a video (ie, a video or still picture that can represent the broadcast program representatively), the program guide service can be diversified, and a natural and effective advertising effect can be obtained. To increase advertising revenue Will.

Therefore, the present invention has been made in view of the above, when the satellite broadcasting receiver provides a program guide service to the user, by configuring the text program content information and the fairy tale advertisement assigned to each channel as a single menu screen Improved channel in satellite broadcasting receiver that can display on monitor and display text program contents information and moving picture reference image of selected broadcasting program as one menu screen when selecting broadcasting program on menu screen The purpose is to provide a method of displaying information.

First, in order to provide improved channel information to a user according to the present invention, advertisement packets carrying data for moving picture advertisement images corresponding to each channel and each channel are provided on a transport stream received by the satellite broadcasting receiving system through a satellite receiving antenna. Reference picture packets carrying data for moving picture reference video for a broadcast program are inserted at predetermined intervals. The advertisement packet identifier (PID) information and each broadcast program identifier (PID) information are used for program information of each channel. The program information packet data, which is included in the program information packet data having the actual broadcast program information, contains character program content information as shown in FIG. 3 as an example or part thereof in FIG. 4 (CH11, CH12) as an example. Shape program contents in figure or figure form as shown The flashy.

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 program number of each channel, and N-bit program representing audio, video, text, etc. of a specific channel. The program information packet data having the program map table (PMT) information of the identifier (PID) information is extracted, and the extracted packet data is converted into an intermediate frequency, demodulated, and error corrected. The reconstruction is then provided to the control block 108 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 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., a moving picture advertisement packet identifier (PID), when a user requests a program guide service while watching satellite television. Based on the information, the moving picture advertisement packets carrying the moving picture advertisement data inserted on the transport stream at predetermined time intervals and the moving picture reference packets carrying the moving picture reference image of the selected broadcast program of a specific channel are extracted and restored to the original signal. The reconstructed moving picture advertisement picture data or moving picture reference picture data of the broadcast program are provided to the MPEG decoding block 104 through the line L13.

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 may allow the tuner and the demodulation block 102 to extract the video advertisement packet data corresponding to the selected specific channel when the broadcast channel menu service request signal is input from the outside. Ad packet identifier (PID) information in the program information of a specific channel (i.e., the selected channel) previously stored 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.

At this time, the base station for transmitting the satellite broadcast signal may be transmitted by inserting the specific moving picture advertising video data for the program guide service for each channel, and also change and transmit the specific moving picture advertising video data assigned to each channel at predetermined time intervals. It may be.

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. And a screen configuration control signal generated on the line L19 to provide a menu generation block 112 and to mix the extracted moving picture 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 by using a decoding technique such as variable length decoding, inverse DCT, inverse quantization, motion compensation, and the like. The advertisement video signal or the moving picture selection broadcast program moving picture reference video signal is restored to the original signal before encoding, and the restored digital broadcasting video signal, moving picture advertising video signal, or moving picture reference video signal of the broadcasting program is transmitted to the next stage through the line L15. The audio signal provided to the video encoding block 106 and the reconstructed audio signal is not shown. It is available in a call handler.

Also, the video encoding block 106 converts a digital broadcast video signal, a moving picture advertisement video signal of a selected channel, or a moving picture reference video signal of a broadcast program into an NTSC or PAL analog video signal provided in the MPEG decoding block 104 described above. The next line L16 is provided to the image synthesizing block 114.

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. A menu screen obtained by transferring the moving picture advertisement video signal on the line L16 or the moving picture reference video signal of the broadcast program and the initial menu screen data on the line L18 to the display side, not shown, is transferred to the display side, not shown.

That is, when the user requests the program guide service, the image synthesizing block 114 displays the moving picture advertisement video signal of the corresponding channel provided through the line L16 or the moving picture reference video signal of the broadcast program and the initial menu screen data provided through L18. Mixing produces one complete menu screen, which is passed to the display side.

Therefore, on the monitor on the display side, 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 moving picture advertisement picture corresponding to a specific channel or a moving picture reference picture of a selected broadcast program are mixed. This menu is displayed or a menu of shape program content information having a shape (i.e., an image which may mean a corresponding program) such as a figure and a picture, as shown in FIG. And a menu screen in which a moving picture advertisement image corresponding to a specific channel or a moving picture reference image of the selected broadcast program is mixed.

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 5.

FIG. 2 is a flowchart illustrating a process of providing, to a monitor, a menu screen including channel information and advertisement or a menu screen including channel information and a reference image of a selected broadcast program in a satellite broadcasting receiver according to an exemplary embodiment of the present invention.

First, in order to implement the improved channel information display according to the present invention, the base station that transmits the satellite broadcasting signal inserts and transmits specific moving picture advertisement image data in the form of a packet for program guide service for each channel, and also transmits to each channel. Reference video data corresponding to the broadcast program (moving video for several seconds that can represent the broadcast program) is inserted and transmitted in a packet form, and at this time, the moving picture advertisement video data of each channel may be changed and transmitted at predetermined time intervals. have.

In addition, the channel information packet on the transport stream includes a delimiter for distinguishing packets of each channel, that is, character program title information or shape program title information in figures and pictures, and identifier (PID) information of at least one moving picture advertisement video data packet. The program information packet including information on broadcast programs of each channel includes packet identifier (PID) information of moving picture broadcast program reference image data corresponding to each broadcast program of 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 identifier (PID) of the corresponding advertisement packet data is fetched, and the retrieved corresponding advertisement packet identifier (PID) is passed to the tuner and demodulation block 102 via the 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. .

Next, the tuner and demodulation block 102 extract only the corresponding moving picture advertisement packets of the selected channel on the received packet stream based on the corresponding moving picture 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 moving picture 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 converted moving picture is restored to the original signal before encoding through the MPEG decoding block 104 and the video encoding block 106, and converted into an NTSC or PAL analog video signal (step 206).

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 corresponding moving picture advertisement packet for the selected channel as described above. The menu generating block 112 converts the channel information and program content information into initial menu screen data (ie, menu screen data occupying the entire monitor) by using a graphic. The generated initial menu screen data is converted into an NTSC or PAL analog signal (step 208).

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 210, the corresponding moving 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. Therefore, on the monitor, as shown in FIG. 3 as an example, a menu screen in which the character program content information and the moving picture advertisement image of the selected channel is mixed is displayed, or only a part (CH11, CH12) shown in FIG. 4 as an example. As described above, a menu screen in which the shape program content information and the moving picture advertisement image of the selected channel is mixed will be displayed (step 212).

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

Of course, by adjusting the sampling rate of the corresponding moving picture advertisement image of the selected channel and the sampling rate of the initial menu screen data, the program content information portion displayed on the monitor may be made larger or the corresponding moving image advertisement image portion may be made larger. 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 moving picture advertisement image of the selected channel to 3: 2, or the respective sampling ratios to the opposite.

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 on each horizontal line for the moving picture advertisement image and the initial screen data, and then a separate signal is obtained. It may be realized by scanning two signals transmitted to each scanning device through the processing path, respectively, on each divided screen.

Next, as described above, when the menu screen in which the character program content information or the shape program content information and the corresponding moving 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, the user selects a particular broadcast program of another channel or of a selected channel, e.g. switches the cursor located on the currently selected channel (e.g., CH11) to another channel (e.g., CH12) (step 214) or whether a particular broadcast program in the selection channel is selected (e.g., the diagonally selected Jurassic Park program is selected diagonally in CH11 of FIG. 5) (step 216).

As a result of the check in step 214, 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 period (eg, 5 seconds, 8 seconds, etc.), that is, in step 218, it is checked whether a channel is changed or a broadcast program is selected by the selected channel within the 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 232 described later to turn off the currently displayed menu screen, and the satellite broadcasting receiving system is automatically switched to the viewing mode.

That is, if there is no change to another channel or broadcast program selection in the selected channel after the user's request for program guidance, a menu screen on which a moving picture advertisement image assigned to the selected channel and text or shape program content information is mixed is displayed on the monitor. Displayed for a predetermined time, and after a predetermined time, the satellite broadcasting receiving system is turned off the menu screen and automatically switched to the viewing mode.

On the other hand, as a result of the check in step 216, if it is determined that the user selected any one of a plurality of broadcast programs in the currently selected channel (for example, Jurassic Park of CH11 shown in Figure 5), Figure 1 Control block 108 retrieves program information data of a selected channel pre-stored in memory block 110, extracts a delimiter (PID) of reference video packet data of a selected specific broadcast program, and tunes and demodulates a block through line L11. 102).

Accordingly, in steps 220 and 224, as in steps 206 and 210 described above, the character or shape program content information and the moving picture reference image of the selected broadcast program in the selected channel (the corresponding broadcast program is displayed. A menu screen is generated by mixing a representative video) and then provided on a monitor on the display side. As a result, as shown in Fig. 5, on the monitor, a menu screen in which the character program content information and the moving picture reference image of the selected broadcast program is mixed is displayed, or only a part (CH11, CH12) is shown in Fig. 4 as an example. As described above, a menu screen in which the shape program content information and the moving picture reference image of the selected broadcast program is mixed will be displayed (step 226).

At this time, the menu screen in which the character or shape program content information displayed on the monitor and the selected broadcast program moving picture reference image is mixed, as described above, the menu screen in which the character or shape program content information and the corresponding moving picture advertisement image of the selected channel are mixed. Can be displayed on the monitor by the same method as that of displaying (i.e., 2: 1 subsampling, 3: 1 subsampling, etc.).

Next, in step 228, when a menu screen in which a character or shape program content information and a moving picture reference image of a selected broadcast program is displayed on a monitor is displayed according to a program menu screen service request from a user, another selection key signal. Checks whether or not is input, i.e., whether the user selects another channel or another broadcast program in the selected channel. The input check of the other selected key signal is performed for a predetermined time (e.g., 5 seconds). , 8 seconds, etc.) (step 230).

In this case, switching to another channel or selecting another broadcast program may be realized by moving, for example, a cursor on a menu screen to a target channel to be switched or to a position of a target broadcast program in a selected channel.

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 228, the process proceeds to the corresponding step, i.e., when the key signal for channel switching is input, the process is described above. The process returns to step 206 to repeat the process thereafter, and when a key signal for selecting another broadcast program in the currently selected channel is input, the process returns to step 220 and repeats the same process thereafter. Will be performed.

On the other hand, if the check result in step 230 determines that another channel or another broadcast program in the selected channel is not selected within a predetermined time period, the process proceeds to step 232, and in step 232 The menu screen currently displayed on the screen 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 the guidance of a broadcast program, the satellite broadcast receiver provides a specific moving picture advertisement image of a selected channel along with text or shape program content information on a menu screen displayed on the monitor. A program guide service is provided by providing a menu screen on which a moving picture reference image of a selected broadcast program and text or shape program content information that can represent a selected specific broadcast program when selecting a specific broadcast program in a selected channel on a menu screen is mixed on a monitor. In addition to the diversification of, natural and effective general advertising and advertising (advertisement) effect of each broadcasting program can be obtained.
