Description

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 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, 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. Provide a specific text advertisement image along with the text program guide information, or make the text broadcasting promotion information or the moving picture broadcasting promotion image of the broadcasting program selected by the user (or the cursor located) on the menu screen translucently on the text program contents information. If it can be provided with a single menu screen, it is possible to obtain a natural and effective advertising effect as well as to diversify the program guide service, which will allow each broadcasting station to increase the additional advertising revenue.

Accordingly, the present invention has been devised in view of the above, when the satellite broadcasting receiver provides the user with a program guide service, Oberlab translucent full-screen translucent text ads assigned to each channel in the text program content information To provide a guide service combined with one menu screen, and to select a broadcast program for a specific channel on the menu screen. It is an object of the present invention to provide an improved method of displaying channel information in a satellite broadcasting receiver capable of providing a guide service combined into one menu screen.

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, the program guide packet comprising a plurality of pre-assigned full-screen translucent text advertisement data packets corresponding to each channel and each in each channel. Full screen corresponding to broadcast program And the N-byte program information packet includes the character program title information, the identifier information of the full-screen semi-transparent text advertisement data packet previously assigned to each channel, and the broadcast program in each channel. And delimiter information of the full-screen translucent text or moving picture broadcasting data packet, wherein the method includes: when the phase broadcasting receiving system is in a viewing mode with the program guide packet data received and pre-stored in the memory area; A first step of checking whether there is a program menu guide service request according to the operation; 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 full-screen translucent text advertisement packets of a selected channel, and the extracted full-screen translucent text advertisement packet delimiter information is retrieved.

This could be a lead, a supporting role, a production company, a production date, or an outline of content.

On the other hand, the full-screen translucent fairy tale broadcast promotional data for the selected broadcast program, as shown in FIG. 5 as an example, assuming that the broadcast program selected by the user is a Jurassic Park movie program filled with diagonal lines on the same road, the selected broadcast. It is a full-screen translucent fairy tale broadcast promotional video for several seconds corresponding to a program (that is, a fairy tale for several seconds that can express the characteristics of the program well).

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 full screen translucent text advertisement packet extraction signal, full screen, provided from the control block 110 via line L11 when the user requests a program guide service while the user is watching satellite television. A predetermined time interval on the transport stream based on the semi-transparent broadcast promotion packet extraction signal or the full-screen translucent video broadcasting packet extraction signal, that is, the text advertisement packet identifier (PID), the full-screen translucent character or the animation broadcasting promotion packet identifier (PID) information. And extracts the inserted text advertisement packet, full-screen translucent text broadcasting promotion packet or full-screen translucent video broadcasting promotion packet to the original signal, and the restored text advertising data and full-screen translucent broadcasting promotional data are transmitted through line L14. Is provided to the text decoding block 108 of the next stage, Translucent broadcast promotion data are provided to the MPEG decoding block 104 via line L13.

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, the control block 110 may allow the tuner and the demodulation block 102 to extract the semi-transparent text advertisement packet data corresponding to the selected specific channel when the broadcast channel menu service request signal is input from the outside. The full-screen semi-transparent character advertisement packet identifier (PID) information in the program information of the 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.

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 generated on the line L21 to provide the menu generation block 114 and to mix the extracted translucent text advertisement text data and the program guide menu with each other to form a menu screen. As the 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 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 a video signal, for example, the video signal is decompressed to the original signal before encoding 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.

Further, in the MPEG decoding block 104, encoding provided from the tuner and the demodulation block 102 via the line L13 when full-screen translucent moving picture broadcasting promotional video is adopted as the corresponding broadcasting promotion information of the selected broadcast program according to the present invention. The translucent moving picture broadcasting promotional video data is restored to the original signal before encoding and then provided to the video encoding block 106 through the line L16.

Accordingly, the video encoding block 106 converts the selected digital broadcast video signal provided in the MPEG decoding block 104 described above or the full-screen translucent moving picture broadcast promotional video signal of the selected broadcast program into an NTSC or PAL analog video signal. Provided to the image composition block 116 through the L17.

Next, in response to the broadcast channel menu service request, the text decoding block 108 transmits the coded full screen translucent text advertisement test data provided from the above-described tuner and demodulation block 102 through the line L14 to the original signal before encoding. The text data for full-screen translucent text ads received, for example, is encoded via techniques such as Hoffman coding, which assigns long or short codes based on the frequency of the generated codes, as is well known in the art. The encoded text data may be decoded into an original signal, and the decoded full-screen translucent text advertisement data is provided to the image synthesis block 116 through the line L18.

Further, in the text decoding block 108, when the full-screen translucent text broadcast promotion image is adopted as the corresponding broadcast promotion information of the selected broadcast program according to the present invention, it is provided from the above-described tuner and demodulation block 102 through the line L14. The encoded full-screen translucent text broadcasting promotional text data is decoded into the original signal before encoding and provided to the image synthesis block 116 through the line line L18.

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 to the display side which is not shown in figure, or which mixed the text data for full screen translucent text ads on the line L18, and the initial menu screen data on the line L20 is delivered to the display side which is not shown in figure.

That is, in the image synthesizing block 116, when the user requests the program guide service, one full menu is obtained by mixing the full-screen translucent text advertisement data of the corresponding channel provided through the line L18 and the initial menu screen data provided through the L20. A screen (a menu screen in which the text menu and the translucent text advertisement are over-transparently overlapped) is generated, and the generated menu screen is transferred 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 corresponding full screen translucent text advertisement of a specific channel semi-transparently overlaid on the menu are mixed. Will be displayed.

Also, in the image synthesizing block 116, when the user selects a specific broadcast program on the menu screen, full-screen translucent text broadcast promotion video or full-screen translucent moving picture promotion of the selected broadcast program selectively provided through line L18 or line L17. Overlapping the image and the initial menu screen data on the line L20 translucently creates the entire menu screen and provides it to the display side. Therefore, on the monitor on the display side, as shown in Fig. 4 and Fig. 5 as an example, a full menu screen overlaid with a full-screen translucent text broadcast promotion video or a full-screen translucent video broadcast promotion video will be displayed.

Next, a process of performing the channel information display method according to the present invention based on the satellite broadcasting reception system having the above-described configuration will be described in detail with reference to FIGS. 1 to 5.

FIG. 2 is a view illustrating a menu screen of a full-screen semi-transparent text advertisement image semi-transparently overlaid on channel information and channel information or a semi-transparent full-screen semi-transparent broadcast-promotion video in a satellite broadcasting receiver according to a preferred embodiment of the present invention. This is a flowchart showing the process of adaptively providing.

First, in order to implement the improved channel information display according to the present invention, in the base station that transmits the satellite broadcasting signal, a plurality of full screen translucent text advertisement image data for program guide service for each channel and full screen translucent for each broadcast program Character promotional video data or full-screen translucent fairy tale promotional video data is inserted and transmitted. At this time, as an example, assuming that there are five full-screen translucent text advertisement images assigned to one channel, the program information packet data having broadcast program information of each channel includes five corresponding to full-screen translucent text advertisements of the corresponding channel. The full-screen translucent advertisement packet identifier (PID) will be included.

Referring to FIG. 2, when a user is watching a phase broadcast television in a state in which program guide packet data, that is, channel information data and program guide information data for each channel, are 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 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. The first delimiter (PID) of the corresponding plurality of full-screen translucent text advertisement packet data is withdrawn, and the first corresponding full-screen translucent text advertisement packet delimiter (PID) is retrieved via line L11 to the tuner and demodulation block 102. To pass.

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 tuner and demodulation block 102, the corresponding full-screen translucent of the selection channel on the packet stream received based on the first corresponding full-screen translucent text advertisement packet identifier (PID) information of the selection channel provided from control block 110. Only the text advertisement packet is extracted, and demodulation and error correction are performed on the extracted corresponding full-screen translucent text advertisement packet data to switch to the encoded transport stream (step 206). 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 full-screen translucent 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 full-screen semi-transparent text advertisements is It is passed to line composition block 116 via line L18 (step 208).

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 first corresponding full-screen translucent text advertisement packet for the selected channel as described above. The menu generation block 114 transfers the channel information and program content information to the initial menu screen data (that is, the menu screen data occupying approximately the entire monitor) by using a graphic. The generated initial menu screen data is converted into an NTSC or PAL analog signal (step 210).

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 full screen semi-transparent text advertisement data on the line L18 and the initial menu screen data on the line L20 are mixed. In other words, the entire menu screen including the translucent text advertisement and the channel information menu is configured in such a manner that the text advertisement image is overlaid on the full channel information.

Thus, on the monitor, as shown in FIG. 3 as an example, a menu screen in which the text program content information for each channel and the text advertisement of the selected channel overlapped in a translucent state over the full screen will be displayed (step 214). ).

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

As a result of the check in step 216, if it is determined that the translucent text advertisement currently being displayed on the menu screen in the translucent state is displayed for a preset time, the control block 110 displays the translucent text displayed so far for the selected channel. It is checked whether P representing the number of advertisements has reached the number m of translucent 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, it is assumed that five different full-screen translucent text advertising images are allocated to the selected channel. If it is determined that all the advertisement images are not displayed, the process returns to step 206 described above and repeats the subsequent process, so that the display of the next full-screen translucent text advertisement image will be executed.

Next, as described above, when the menu screen in which the character program content information and the corresponding full-screen translucent text advertisement of the selected channel is displayed on the monitor according to the program menu screen service request from the user, the control block 110 ), The user changes the channel or selects a specific broadcast program of the selected channel, for example, switches the cursor located on the currently selected channel (eg CH11) to another channel (eg CH12) (step 220) or It is checked whether or not a specific broadcast program in the selected channel is selected (for example, a baseball game that is rounded diagonally in CH12 of FIG. 4) (step 222).

If it is determined in step 220 that another channel is selected by the user, the process returns to step 206 and repeats the subsequent steps. During a predetermined time period (eg, 5 seconds, 8 seconds, etc.), that is, in step 224, 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 a broadcast program of the selected channel, the process proceeds to step 238 of FIG. 2B to be described later, in which the currently displayed menu screen (the screen overlaid with the menu and the text advertisement is over-transparent) is turned off. The satellite broadcasting receiving system automatically switches to viewing mode.

That is, if there is no change to another channel or a broadcast program in the selected channel after the user's request for program guidance, the full screen semi-transparent text advertisement image and channel information menu assigned to the selected channel is semi-transparently overlaid on the monitor. The screen is displayed for a predetermined time, and after a predetermined time, the satellite broadcasting receiving system turns off the menu screen and automatically switches to the viewing mode.

On the other hand, as a result of the check in step 222, the user selects one of a plurality of broadcast programs in the currently selected channel (for example, the baseball relay program of CH12 shown in FIG. 4 or the CH11 shown in FIG. 5). If it is determined that the Jurassic Park program) has been selected, processing proceeds to step 226 of FIG. 2B.

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.

Referring to FIG. 2B, in step 226, any one of a plurality of broadcast programs in the currently selected channel by the user (e.g., the baseball relay program of CH12 shown in FIG. 4 or the CH11 shown in FIG. When the Jurassic Park program) is selected, the program guide information data of the selected channel pre-stored in the memory block 110 is searched, and the identifier (PID) of the full-screen semi-transparent broadcast promotion packet data of the selected broadcast program is retrieved, and is output through the line L11. Pass to tuner and demodulation block 102.

At this time, the full-screen semi-transparent broadcast promotion packet data of the selected broadcast program extracted from the tuner and the demodulation block 102 is, for example, as shown in FIG. 4, the baseball program in which the broadcast program selected by the user is filled with diagonal lines in the same plane. Assuming a program, it may be full-screen translucent text broadcast data recording player, team standing, team history, team batting rate, team defense rate, team home run, remaining game, etc. for each team running the game. As an example, as shown in FIG. 5, assuming that the broadcast program selected by the user is a Jurassic Park movie program filled with diagonal lines on the same plane, a full-screen translucent fairy tale broadcast promotion video corresponding to the selected broadcast program (ie, For example, the data may be a fairy tale data for several seconds, which may well indicate the characteristics of the program.

Thus, in steps 228 and 230, as in steps 210 and 212 described above, full-screen semi-transparent text or moving picture broadcasting for the selected broadcast program in the selected channel on the character program content information of each channel. The promotional image is translucently overlaid and a mixed menu screen is generated and provided on the monitor on the display side. As a result, as shown in Figs. 4 and 5, on the monitor, a menu screen in which the character program content information of each channel and the full-screen translucent text of the selected broadcast program or the video clip of the video broadcast will be displayed (step). 232).

Next, in step 234, as described above, when providing the program menu screen service, the character program content information of each channel and the full-screen translucent text of the selected broadcast program or the moving picture broadcasting promotion image are mixed according to the user's program selection. When the menu screen is displayed on the monitor, it is checked whether another selection key signal is input, that is, whether the user selects another channel or another broadcast program in the selection channel. The input check of 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 a corresponding step, i.e., when a key signal for channel switching is input, the process is described above. The process returns to step 206 of FIG. 2A to repeat the process thereafter, and 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 will be repeated later.

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 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 the user requests the guidance of the broadcast program, the satellite broadcasting receiver displays the full screen semi-transparent text advertisement image assigned to the selected channel together with the text program content information of each channel on the menu screen displayed on the monitor. Allocate full-screen translucent text-transfer video or full-screen translucent of the selected broadcast program that can be provided in a semi-transparent over-wrap and that can represent the particular broadcast program selected when the user selects a particular broadcast program in the selected channel on the menu screen. By providing an image on the monitor with each channel translating over-transparently on the character program contents information, it is possible to diversify the program guide service, and to promote natural and effective general advertisement and promotion of each broadcasting program (that is, advertisement). You can get it.
