Description

How to Display Channel Information of Complex Satellite Broadcasting Receiver

The present invention relates to a method for displaying program information in a composite satellite broadcast receiver, and more particularly, when a user switches a channel in a viewing mode of a composite satellite broadcast receiver that can simultaneously receive a satellite broadcast signal and a cable broadcast signal. A channel information display method of a composite satellite broadcast receiver suitable for providing broadcast program information of a selected cable broadcasting channel as a banner menu.

In recent years, the broadcast method using satellites, which is rapidly expanding in use, uses a satellite tuner equipped with a satellite receiver to tune a channel selected by a user by inputting an IF signal received through a low noise converter. In addition, such satellite broadcasting receivers can maximize the use of channels, improve the quality of video and audio signals, and facilitate the transmission of additional digital service data.

In recent years, not only satellite broadcasting but also cable broadcasting using cable has been rapidly spreading. When a subscriber (that is, one receiver) wants to receive all of these broadcasting signals, the frequency of each broadcasting is different. Due to the different bands, all-in-one type can be equipped with a satellite tuner and a cable broadcast tuner separately or to process two types of broadcasts through separate signal processing paths (ie, a satellite signal processing path and a cable broadcast signal processing path). Alternatively, an external composite tuner is employed in the receiver.

On the other hand, in the television employing the complex tuner as described above, a separate switching key for switching each broadcasting mode (ie, satellite broadcasting mode and cable broadcasting mode) is provided or a menu screen for switching the broadcasting mode is provided by software. We adopt technique to do.

In addition, the satellite broadcasting receiver adopts a technique that allows the user to select a specific channel that the user wants to watch using the numeric keys as in a general television and the channel that the user wants to watch using the channel up / down keys. In contrast, when a program guide menu according to a user's request is being displayed on a monitor, the user selects a specific channel on the menu so that a user can select a specific channel to watch.

On the other hand, when the satellite broadcasting receiver performs channel switching for satellite broadcasting or cable broadcasting through various methods as described above, the satellite broadcasting receiver displays a banner menu with detailed program information on the channel to be switched. To display for a preset number of seconds (e.g., 3-4 seconds, etc.), allowing users (or viewers) to preview detailed program information for the channel they have selected to switch to via this banner menu. You will know.

At this time, in the case of the satellite broadcasting channel, the guide packet containing the guide information for each program of each channel is already extracted at the same time as the power-on of the receiver and stored in the memory block. Can be configured. Here, the detailed program information on the banner menu of the satellite broadcasting channel configured includes, for example, the channel number, the program name, the start time of the program, the airing time, the class of the program, the voice mode, the presence or absence of a paid broadcast, the current date and time, and the like. do.

However, in the case of cable broadcasting, unlike in the case of the above-mentioned satellite broadcasting, since there is no detailed information on the program of each corresponding channel, only the channel number, program name, current date and time and the like can be provided at the time of channel switching selection. There was no. Therefore, when the channel selected by the user is a cable broadcast channel, the user cannot access detailed information on the broadcast program of the cable channel selected to switch, and this is expressed only by users' desire.

Therefore, if the composite satellite broadcast receiver can provide the detailed program information of the switching channel for the cable broadcast channel in any form, it may further enhance the usability of the composite satellite broadcast receiver.

The present invention has been devised in view of the above, and extracts detailed additional information on the corresponding broadcast program of the cable broadcast channel switched at the time of switching from the viewing mode to the cable broadcast channel, and uses the extracted additional information. It is an object of the present invention to provide a channel information display method of a composite satellite broadcast receiver capable of displaying a banner menu including corresponding program detailed information of a selected cable broadcasting channel in a predetermined region of an image of a program of a current broadcasting channel.

It is another object of the present invention to extract detailed additional information of each broadcast program added to each broadcast program signal of a corresponding channel during automatic tuning of a cable broadcast channel, and the selected channel switched in the viewing mode is used for cable broadcast and satellite broadcast. In the case of overlapping overlapping channels, a banner menu including detailed additional information on a corresponding corresponding cable broadcast program or a banner menu containing detailed information on a corresponding corresponding satellite broadcast program is adaptively applied to a predetermined image of the broadcast program of the current channel. A channel information display method of a composite satellite broadcast receiver that can be displayed in an area is provided.

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

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

Figure 1 shows a block diagram of a typical composite satellite broadcast receiver suitable for applying the channel information display method of the composite satellite broadcast receiver according to the present invention.

As shown in the figure, a typical composite satellite broadcast receiver includes a tuner and demodulation block 102, an MPEG decoding block 104, a video encoding block 106, a video processing block 108, a control block 110, A first memory 112, a second memory 114, a menu generation block 116, and an image synthesis block 118.

1, the tuner and demodulation block 102 extracts, i.e., channel information, program information, and the like, inserted into a transport stream received through an antenna when the satellite broadcast receiver is powered on. N-bit program identifier for channel information packet data with program combination table (PAT) information of N-bit program identifier (PID) information for program number of each channel and audio, video, text, etc. of a specific channel. Extract program information packet data having program map table (PMT) information as (PID) information, and restore the extracted packet data to a transport stream through a process of converting to intermediate frequency, demodulating and error correction. And then to the control block 110 described below via line L12.

In this case, 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 received through the satellite channel when a specific channel of the desired satellite broadcast is selected by the user. It is used to tune a particular satellite channel selected in the stream, and is also used as actual content information of the guide menu screen when the user is required to provide (i.e. display) a plurality of channel information and broadcast program information for each channel.

In addition, the tuner and demodulation block 102, in response to the automatic tuning control signal provided from the control block 110 via line L11, when the user selects automatic tuning and storage of the cable broadcast channel, the plurality of respective cable broadcast channels. Only the valid broadcast channel carrying the broadcast signal which can be viewed is automatically tuned, and the effective broadcast channel information thus tuned is provided to the control block 110 through the line L12.

Further, the tuner and demodulation block 102 are received via a broadcast signal receiver (i.e., satellite receiving antenna, cable, etc.), not shown, based on the tuning control signal provided from the control block 110 described later via line L11. The tuned broadcast channel selected by the user is tuned to the satellite or cable broadcast signal, and the tuned broadcast channel signal is demodulated to the original signal before transmission. When the satellite broadcast signal is tuned, the demodulated satellite broadcast channel signal is taken from line L13. Is provided to the MPEG decoding block 104, and the demodulated cable broadcast channel signal is provided to the video processing block 108 via line L14 when the cable broadcast signal is tuned. In such a tuner and a demodulation block, for example, a pending tuner is filed by the applicant of the Korean Patent Office on October 31, 1994 under the name of “Tuner for Satellite and Cable Broadcasting” (Patent Application No. 94-28287). It can be adopted.

Next, in MPEG decoding block 104 the spatially and spatially of the compressed and encoded audio and video signals, e.g. video signals, of the selected satellite broadcast channel provided from the above-described tuner and demodulation block 102 via line L13. In consideration of the correlation, the compressed coded 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, and the digital satellite broadcast video signal reconstructed here is Provided to video encoding block 106.

The video encoding block 106 converts the digital broadcast video signal of the selected satellite channel provided by the MPEG decoding block 104 described above into an NTSC or PAL analog video signal, and then outputs the image synthesis block 118 through the line L15. )

On the other hand, the video processing block 108 processes the broadcast program video signal of the tuned cable channel provided from the above-described tuner and demodulation block 102 via the line L14 in the cable broadcast viewing mode, for example, level amplification, noise removal. Various signal processes such as gain control and the like are provided to the image synthesis block 118 on the output side through the line L16.

On the other hand, the control block 110 includes, for example, a microprocessor for performing overall operational control of the receiver, generating a signal for requesting acquisition of a guide packet via line L11 when the receiver is powered on, When the guide packet data extracted from the transport stream is input through the line L12, these data are sequentially stored in the first memory 112, and a corresponding cable is input when an operation signal for effective channel automatic tuning of the cable broadcast is input from the outside. A second automatic tuning control signal for automatic tuning of a valid channel of the broadcast (that is, a channel containing a viewable broadcast signal) is generated on the line L11, and when the effective channel information of the cable broadcast automatically tuned through the line L12 is inputted, the second channel is transmitted. It stores in the memory 114.

That is, guide packet data for satellite broadcasting is stored in the first memory 112, and effective channel information of automatically tuned cable broadcasting is stored in the second memory 114.

In addition, the control block 110 generates a tuning control signal on the line L11 for tuning the selected channel of satellite broadcasting or cable broadcasting through switching to the same broadcasting mode or another broadcasting mode according to a user's operation. One tuner and demodulation block 102 will tune the satellite or cable channel selected by the user in response to a tuning control signal on line L11.

Meanwhile, as described above, when performing channel switching according to a user's operation, the controller controls generation of a banner menu including detailed information about a program of a selected channel, wherein the generated banner menu is mixed with the image of the current channel. It is displayed on the monitor for a predetermined number of seconds (for example, 3-4 seconds, etc.), and the control of the banner menu is different from that of the satellite broadcasting mode and the cable broadcasting mode.

That is, in the case of the satellite broadcasting channel, since the guide packet containing the guide information for each program of each channel is already extracted at the same time as the power-on of the receiver and is stored in the first memory 112, the banner using the pre-stored guide information is used. The menu may be configured smoothly, but unlike in the case of satellite broadcasting, in the case of cable broadcasting channel, since there is no detailed information on the program of each corresponding channel, the control block 110 selects the tuning and simultaneously selects the current program of the selected channel. Extract additional information about (e.g., voice multi-mode, stereo / mono mode, etc.). In addition, the control block 110 checks whether there is an e-mail received through the general telephone line, checks whether the corresponding channel is set to the locked state (lock state) by the administrator, and extracts it from here. Additional information on the corresponding program of the selected cable broadcasting channel, information on receiving e-mail, and lock state information of the selected cable channel are used as detailed information for generating a banner menu of the cable broadcasting channel.

Here, the lock of the cable broadcast channel is preset by an administrator (for example, a home parent, etc.), and the lock setting and the release of the broadcast channel are normally set to be possible only by the administrator ID.

Furthermore, the control block 110 generates an image output control signal on the line L19 when the channel switching signal is input from the outside, and provides the image output control signal to the image combining block 118 which will be described later. In response to the output control signal, any one of the image of the selected satellite broadcasting channel, the image of the selected cable broadcasting channel, the image of the satellite broadcasting channel mixed with the banner menu, and the image of the cable broadcasting channel mixed with the banner menu is selected and displayed. Will print to the side.

Next, in the menu generation block 116, when the channel switching signal is input, the detailed program information data of the satellite broadcasting channel for which the switching provided from the above-described control block 110 is selected via the line L17 or the cable broadcasting channel for which the switching is selected is selected. The additional information data is configured into a banner menu screen using graphics, and the configured banner menu screen data is converted into an NTSC or PAL analog signal and then provided to the image synthesis block 118 on the output side through line L18.

That is, in the menu generation block 116, when the channel selected for switching is the satellite broadcasting channel, for example, the channel number, the program name, the start time of the program, the airing time, the class of the program, the voice mode, the presence or absence of a paid broadcast, the current date and time. If a channel is selected for switching, and the selected channel is a cable broadcasting channel, as shown in FIG. 4, for example, an icon indicating whether the channel number, the program name, the current date and time, and the voice of the selected channel program are multiplied ( 41), a banner menu including an icon 42 indicating whether a selected channel program is stereo, an icon 43 indicating whether an e-mail is received, and an icon 44 indicating whether a selected channel is locked or not are configured.

In FIG. 4, reference numeral A denotes a video area of a channel currently being viewed, and reference numeral B denotes a banner menu area having detailed program information of a cable broadcasting channel for which switching is selected.

In addition, in the menu generation block 116, when the channel selected for switching is a duplicate channel in which the satellite broadcasting and the cable broadcasting are overlapped, that is, in the case of cable broadcasting, channels 1 to 158 are generally considered in consideration of the transmission bandwidth. Is allocated, and in the case of satellite broadcasting, channels 100 through 999 are allocated, and in this case, channels 100 through 158 become duplicate channels in which satellite broadcasting and cable broadcasting are duplicated. If the channel selected by switching is such a duplicate channel, as an example, as shown in FIG. 5, a message inquiring whether to select a cable channel at the same time as a banner menu having detailed program information on the cable broadcasting channel of the corresponding channel. Happens simultaneously. That is, in FIG. 5, reference numeral A is a video region of a current channel, B is a banner menu region having detailed program information on a cable broadcasting channel of a duplicate channel, and C is a pop-up menu region with a selection query message.

On the other hand, the image synthesizing block 118 selects and outputs the image output on the line L15 to the display side when the viewing mode is the satellite broadcasting mode based on the image output control signal provided from the control block 110 through the line L19. When the viewing mode is the cable broadcasting mode, the video output on the line L16 is selected and provided to the display side.

Also, in the image synthesis block 118, when the user performs channel switching in the viewing mode, in response to the output control signal provided through the line L19, the image of the satellite broadcast channel on the line L15 or the cable broadcast channel on the line L16 The image and the banner menu screen (or a menu screen consisting of a banner menu and a pop-up menu) provided from the line L18 are mixed, and thus the mixed image is provided to the display side.

Therefore, on the monitor on the display side, not shown, as shown in FIG. 4 as an example, an image or a satellite broadcast image of a cable broadcasting channel having only a banner menu is displayed or as shown in FIG. 5 as an example, a banner menu. An image of a cable broadcasting channel or a satellite broadcasting image having a pop-up menu may be displayed.

As a result, the users (or viewers) can know in advance the detailed program information of the channel (especially the cable broadcasting channel) for which the user has selected the switching through the banner menu displayed for several seconds during the channel switching.

Next, a detailed description will be given of a process of providing, as a banner menu, detailed program information of a cable broadcasting channel whose switching is selected at the time of channel switching in the composite satellite broadcasting receiver having the above-described configuration.

Example 1

FIG. 2 is a flowchart illustrating a process of providing detailed program information of a channel selected for switching in a channel switching in a composite satellite broadcasting receiver according to the present invention.

First, in the present embodiment, the guide packet of the satellite broadcasting channel is extracted and stored in the first memory 112 in the state where the receiver is turned on (step 202), and the effective channel of the cable broadcasting according to the user's selection (or request). It is assumed that (the channel on which the broadcast signal is carried) is automatically tuned so that the valid channel information is stored in the second memory 114 (step 204).

As described above, when the receiver is in the viewing mode while the guide packet of the satellite broadcast channel is extracted and pre-stored and the channel information on the effective channel of the cable broadcast is pre-stored (step 206), a channel switching signal is received from the outside. In step 208, when it is determined that the channel switching signal is input, the control block 110 determines whether the channel selected for switching is a cable channel or a satellite broadcasting channel. It is checked whether or not it is recognized (step 210).

As a result of the check in step 210, if the switched selected channel is a satellite broadcast channel, the first memory 112 is searched and detailed information about the corresponding program (that is, the program broadcasted at the current time) of the selected channel is retrieved. (Step 212), the extracted program detailed information is configured into a banner menu screen using graphics (step 214), and the mixed banner menu screen and the image of the currently broadcast channel (satellite channel or cable channel) are mixed and mixed. An image is generated (step 216).

Therefore, on the monitor, a banner menu screen having detailed program information for the satellite broadcasting channel whose switching is selected is displayed for a predetermined number of seconds (for example, 3-4) in a predetermined region (for example, the upper region of the screen) of the current channel image. Seconds, etc.) (steps 224, 226), and after a predetermined number of seconds the current channel is automatically switched to the particular satellite broadcast channel selected by the user (step 228). In step 226, t represents the display time of the preset banner menu, and n represents the current display duration of the banner menu.

In this case, detailed program information of the satellite broadcasting channel displayed as a banner menu may be, for example, a channel number, a program name, a program start time, a broadcast time, a program rating, a voice mode, whether paying broadcasting is present, and a current date and time. There will be.

Meanwhile, as a result of the check in step 210, when the channel selected by the user is a cable broadcasting channel, the control block 110 tunes the selected channel based on the effective channel information previously stored in the second memory 114. Then extract additional information about the program on the channel, i.e., extract the voice multi-mode and stereo / mono-mode information of the program, and also check whether there are any e-mails received over a regular telephone line, It is checked whether the switched selected cable channel is set to the locked state (locked state) by the administrator (step 218).

Next, the menu generation block 116 includes an icon corresponding to each extraction information based on the check result as described above, i.e., voice multi-mode, stereo / mono mode, e-mail reception or lock status. For example, as shown in FIG. 4, a banner menu screen is generated, i.e., a channel number, a program name, a current date and time, an icon 41 indicating whether the selected channel program is multiplied by voice, and an icon indicating whether or not the selected channel program is stereo ( 42), a banner menu screen is generated including an icon 43 indicating whether an e-mail is received and an icon 44 indicating whether a selected channel is locked (step 220).

Then, in step 222, the image of the currently airing channel (satellite channel or cable channel) and the banner menu screen of the selected cable channel is mixed to generate a mixed image, and thus to the switched selected cable broadcasting channel A banner menu screen having detailed program information about the current channel image is displayed for a predetermined number of seconds (e.g., 3-4 seconds, etc.) in a predetermined area (e.g., an upper area of the screen) (steps 224, 226). After a predetermined number of seconds, the current channel is automatically switched to the particular cable broadcast channel selected by the user (step 228).

As a result, according to the present embodiment, the users (or viewers) can know in advance the detailed program information of the cable broadcasting channel that the user has selected to switch through the banner menu displayed for several seconds when the channel is switched.

At this time, the users (or viewers) continuously select the next channel or select the channel without broadcasting the program for the selected channel while viewing the detailed program information of the selected and selected cable channels displayed for several seconds when the channel is switched. You can also cancel.

Example 2

The greatest technical gist of the present embodiment is that when a channel selected by a user is a duplicate channel, that is, a duplicate channel allocated by overlapping satellite broadcasting and cable broadcasting (that is, channels 100 through 158), In addition to providing a banner menu for cable broadcasting programs, a pop-up menu containing a message asking whether to select cable broadcasting or satellite broadcasting is provided. The desired specific broadcast channel is selected and detailed program information for this selected specific broadcast channel (satellite broadcast channel or cable broadcast channel) is provided for several seconds as a banner menu.

3 is a flowchart illustrating a process of providing detailed program information of each channel when a channel selected for switching at the time of channel switching is a redundant channel in the composite satellite broadcasting receiver according to the present embodiment.

Referring to FIG. 3, steps 302 to 316 are simplified in their representation but are substantially the same as the above-described steps 202 to 226 of the first embodiment, and are switched by the user. When the selected channel is not a duplicate channel, a process of providing a banner menu for a satellite broadcast channel or a cable broadcast channel is shown, and a detailed description thereof will be omitted in order to avoid unnecessary overlapping description for the sake of brevity of the specification. Therefore, the following description will focus on the steps 318 to 338 representing the technical idea in the present embodiment.

First, the guide packet of the satellite broadcast channel is extracted and stored in the first memory 112, and the effective channel (channel on which the broadcast signal is carried) of the cable broadcast is automatically tuned so that the corresponding effective channel information is stored in the second memory 114. As a result of the check in the step 310 of determining whether the switched selected channel is a duplicate channel when the channel switching signal is input in the state, that is, when the switched selected channel is a duplicate channel (channels 100 to 158), that is, as an example As shown in FIG. 5, when the switched selected channel is the 100 channel, the control block 110 tunes the switched 100 cable channel based on the effective channel information previously stored in the second memory 114, and then 100 times. Extract additional information about the program on the cable channel, i.e., extract the voice multi-mode and stereo / mono mode information of the program, and also receive electronic And checking whether or not the present, it is checked whether or not there is switching the selected cable channel is set to the lock state (locked state) by the administrator.

Then, based on the voice multi-mode, stereo / mono mode, e-mail reception, and lock status, a banner menu screen of cable channel 100 including an icon corresponding to each extraction information is generated, that is, as an example. As shown in Fig. 5, the channel number, program name, current date and time, an icon 51 indicating whether the selected channel program is multiplied by voice, an icon 52 indicating whether the selected channel program is stereo or not, and whether or not an e-mail is received A menu screen is created with a banner menu (B) including an icon (53), an icon (54) indicating whether a selected channel is locked, and a pop-up menu (C) containing a message asking whether to select a cable channel ( Step 318).

Next, in step 320, the menu screen consisting of a banner menu and a pop-up menu and the image of the currently airing channel (satellite channel or cable channel) are mixed to generate a mixed image, and the resultant cable 100 is generated in the cable broadcasting channel 100. A menu screen comprising a banner menu having detailed program information and a pop-up menu containing an inquiry message is displayed for a predetermined number of seconds (for example, 5-10 seconds, etc.) in a predetermined region of the current channel image (steps 322 and 324). .

At this time, if the user selects the Yes button in the pop-up menu of FIG. 5 within the predetermined time t, the cable channel 100 is selected, and if the No button is selected, the satellite channel 100 is selected.

Therefore, when cable broadcasting or satellite broadcasting is selected within a predetermined time period, banner menu display and channel switching of the corresponding channel (cable broadcasting or satellite broadcasting) program corresponding to the selection are performed. It automatically switches to the corresponding satellite broadcasting channel.

That is, if the Yes or No button is not selected within the predetermined time t as a result of the check in steps 322 and 324, the process proceeds to step 338, where the current channel is It automatically switches to the satellite broadcasting channel of 100 duplicated channels selected by the user.
