Description

Channel Information Service Method in Satellite Broadcast Receiver

The present invention relates to a technique for servicing channel information in a satellite broadcasting receiver. More particularly, the present invention relates to a call sign and a logo of a selected (or switched selected) channel when a user requests a guide menu service or a channel switching request from a user. A channel information service method in a satellite broadcast receiver suitable for performing a channel information service including logo and channel information (and / or program guide information).

Recently, the satellite broadcast tuner is tuned to a user-selected channel by inputting an IF signal received through a low noise converter into a satellite broadcast receiver which is rapidly expanding its use. This satellite broadcast receiver maximizes channel utilization. In addition to improved video and audio signal quality, and ease of transmission of additional digital service data, significant improvements in the user interface are significant.

Meanwhile, in satellite broadcasting, a transmission signal of a digital broadcasting signal received from a satellite body to a satellite broadcasting receiver through a fixed channel is restored to a transport stream through a process of converting to an intermediate frequency, demodulating, and error correction. The transport stream includes program service data such as television broadcast and data broadcast and program guide data.

That is, satellite broadcasting transmits data to the satellite broadcasting receiver through a packet aging based on the MPEG-2 standard, for example, in a packet stream of 188 bytes, in which 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 broadcast receiver extracts program guide packets inserted at intervals of several seconds between program service data packets based on the header information (ie, PID) when the power is turned on by the user. (Ie, channel guide information and channel identifier (CID), program information and program identifier (PID), text information and text identifier (TID), etc. of each channel) are stored in a 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.

Meanwhile, the satellite broadcasting receiver provides various user interfaces such as, for example, a program guide screen service and a channel banner screen service, which are serviced in the form of a menu screen using a prepared graphic tool.

That is, when a user requests a program guide service when the satellite broadcasting receiver is in a viewing mode or a standby mode, channel information previously stored in a memory area and program information of the corresponding channel (that is, channel information and a program that can be displayed on a monitor). By using a graphical tool prepared by extracting the information), a guide menu screen having a configuration as shown in FIG. 5A is configured as an example, and then displayed on a monitor. Referring to FIG. 6A, the program guide menu screen includes, for example, a program guide character area 61, a program guide information display area 62 of a selected channel, a program progress time display area 63, and a channel-specific list display area ( 64). At this time, in the program guide information display area 62, for example, the channel number of the selected channel (that is, the channel where the cursor is currently located), the program name, the start time of the program, the broadcast time, the rating of the program, the voice mode, the pay Information such as broadcast status and current date and time is displayed.

Similarly, if the user switches the channel currently being watched to any other channel while the satellite broadcasting receiver is in the viewing mode, the graphics prepared by tuning the switching selected channel and retrieving program content information of the switching selection channel previously stored in the memory area. As an example, a tool is used to configure a channel banner screen with the configuration as shown in FIG. 5B, and then display it on a monitor. Referring to FIG. 6B, the banner screen includes, for example, a channel banner area 66 and a channel program area 68 displaying a program of a switching channel, and the channel banner area 66 is a channel number display area ( 66a) and program guide information display area 66b. In addition, in the program guide information display area 66b, information such as a program name, a program start time, a broadcast time, a program grade, a voice mode, and the presence or absence of paid broadcasting is displayed.

On the other hand, satellite broadcasts have hundreds of satellite channels, and there is a tendency for specialization by a plurality of channel groups. When the number of available channels (that is, effective channels having a broadcast signal) is small, a user may select a satellite channel. Although there is no difficulty in memorizing and using the numbers directly, it is practically impossible for the user to remember all of these large numbers of available channel numbers when there are a large number of available channels (at least dozens of available channels).

That is, when receiving the program guide menu screen or the channel banner screen as described above, the user selects the channel or channel selected by the user on the program guide menu screen unless the user remembers the call sign (or channel name) of the corresponding channel. I couldn't figure out what happened to the callsign for the selected channel.

As a result, for example, if a user wants to watch and select a KBS broadcast channel on a program guide screen, it is very difficult to select the viewing of the channel unless the user himself or herself remembers the channel number of the KBS. When a user wants to select a KBS broadcasting channel for watching a specific program to air, if the user does not know the channel number of the KBS, the user scrolls through all the channels on the program guide screen to find a specific program of the KBS channel that he / she wants to watch. There was no choice but to select the corresponding channel, and this cumbersome operation is a big factor that causes a deterioration of user service.

Therefore, in view of this, if you use the call sign of each channel (e.g. KBS, MBC, SBS, etc.) and the logo (figure including figures or characters) for each satellite channel, By effectively remembering, it is possible to more usefully use the available channels for viewing selection, that is, to improve user convenience. However, at present, no consideration has been given to this point.

Accordingly, the present invention has been made in view of the above, and when the program guide screen service request, using the call sign and logo index information included in the program guide information, the pre-stored call sign and logo information of the selected channel is extracted, and An object of the present invention is to provide a channel information service method in a satellite broadcasting receiver capable of providing a service of a program guide menu screen including a call sign and a logo of a selected channel.

Next, a process of providing a channel information service including a logo and a call sign of a selection channel or a switching selection channel in the satellite broadcast receiver having the above-described configuration will be described.

3 is a flowchart illustrating a process of providing a channel information service including a channel logo and a call sign in response to a request for a guide screen service in a satellite broadcasting receiver according to an exemplary embodiment of the present invention.

First, in order to realize a channel information service according to the present invention, a satellite broadcasting receiver stores call sign and logo data of each channel, and program information packet data on a transport stream received through a satellite antenna is allocated to each channel. The index information of the call sign and the logo is included. Here, the index information may be, for example, an address signal of a memory in which call sign and logo data of each channel are stored.

At this time, the call sign and logo index of each channel included in the program information packet data may transmit, for example, two bytes of reserved information, and the call sign and logo index information of each channel may be provided by the user. When a channel is provided for a predetermined time (e.g., 3-4 seconds, etc.) preset on the monitor when requesting or performing channel switching, the corresponding channel for insertion on the displayed program guide menu screen or banner screen ( Used to fetch callsign and logo data of the selected channel or switched selected channel).

Accordingly, in the present invention, program guide data for each channel is pre-stored in the first memory block 110 and call sign data of each channel is pre-stored in the second memory block 112 for convenience of explanation and improvement of understanding. It is assumed that logo data of each channel is pre-stored in the third memory block 114.

Referring to FIG. 3, when a user is watching a phase broadcast signal 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 first memory block 110 of FIG. 1. (Step 302), it is checked whether there is a program menu guidance service request (step 304).

If it is determined in step 304 that there is a request for a program menu guide service from the outside, the control block 108 of FIG. 1 extracts program information data for each channel previously stored in the first memory block 110. Then, the data is transferred to the menu generation block 116 (step 306), and the program information packet data stored in the first memory block 110 is searched to read index information for the selected channel on the menu screen (step 308). Here, the channel selected on the program guide menu screen may be a channel currently being viewed, and may be a channel in which a cursor (ie, a cursor on the program guide menu screen) that is movable up, down, left, and right according to a user key operation is located.

In addition, the control block 108 extracts the call sign and logo data of the selected channel pre-stored in the second and third memory blocks 112 and 114 based on the index information of the selected selected channel, and the menu generation block through the line L17. Forward to 116 (step 310). At this time, the control block 108 generates a screen configuration control signal for selecting screen data on the line L18 as the output on the line L19.

Therefore, the menu generation block 116 constructs menu screen data including the call sign and the logo of the selected channel (step 312), and the menu screen data thus constructed is transferred to the display side, not shown, through the image synthesizing block 118. On the monitor not shown, a menu screen as shown in FIG. 5A is displayed as an example (step 314).

As an example, assuming that the channel selected on the menu screen is CH14 filled with diagonal lines in FIG. 5A and that the channel name of CH12 is KBS, the displayed menu screen is the logo display area 51 of the selected channel and the channel name display area of the selected channel ( 52, the guide information display area 53 of the selected program in the selected channel, the progress time display area 54 for each program, and the list display area 55 for each channel. In this case, in the guide information display area 53 of the selected program, for example, the channel number of the selected channel, the name of the selected program (that is, the name of the program where the cursor is located), the start time of the program, the broadcast time, the class of the program, Information such as voice mode, paid broadcasting, and current date and time are displayed.

Next, as described above, the program guide menu screen including the call sign and the logo information of the selected channel is displayed on the monitor to check whether the selected channel is changed, that is, whether the cursor position is changed to another channel. (Step 316), the check of this channel change is performed for a predetermined time, such as 20 seconds, 30 seconds, etc., for a predetermined time period (step 318).

As a result of the check in the step 316, if it is determined that the selected channel is changed to another channel within a predetermined time, the process returns to the above-described step 308 to repeat the subsequent steps, that is, the first memory block The program information packet data stored in 110 is searched to retrieve call sign and logo index information of the change channel, and the second and third memory blocks 112 and 114 are based on the call sign and logo index information of the changed change channel. The call sign and logo data of the change channel stored in the channel are extracted, and the guide menu screen is constructed using the extracted call sign and logo data, thereby displaying the logo display area 51 and the channel name display area on the guide menu screen shown in FIG. In 52, logo and call sign information of the change channel is displayed.

That is, in the present invention, whenever the selection channel is changed on the program guide menu screen, the display of the guide menu screens including the logo and call sign information of the changed channel is repeated through the above-described steps 308 to 316. Will be repeated.

On the other hand, in step 318, it is checked whether or not the current time t that has counted the display time of the guide menu screen has reached a preset time n. If it is determined that t = n is not found, the process is performed. In step 314, a continuous check is performed on the channel change in the menu screen display, and when it is determined that the current time t reaches a predetermined time n, the process proceeds to step 320. In operation 320, the program guide menu screen currently displayed on the monitor is turned off, and the satellite broadcasting receiver is switched to the viewing mode. Thus, on the monitor, the broadcast program of the channel that was first watched will be displayed.

When the guide menu screen service stop request signal is input from the outside even when a predetermined time does not pass while the guide menu screen is being displayed, the satellite broadcasting receiver turns off the guide menu screen and immediately switches to the viewing mode.

That is, when the program guide menu service request is made through the above-described process, the guide menu screen including the logo and call sign information of the selected channel is configured and displayed on the monitor. Through the logo and call sign information, the channel name of the corresponding channel can be recognized with certainty, so that operations such as selection and switching of the desired channel can be performed more smoothly.

Next, a process of servicing a banner screen including a logo and call sign information of a switching channel on a monitor when the user performs channel switching in the viewing mode according to the present invention.

Referring to FIG. 4, when a user is watching a phase broadcast signal 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 first memory block 110 of FIG. 1. (Step 402), the control block 108 checks whether or not a channel switching signal is input (step 404).

If it is determined in step 404 that the channel switching signal is input, the control block 108 of FIG. 1 extracts program information data of the switching channel previously stored in the first memory block 110 to generate a menu. Transfer to block 116 (step 406), and search the program information packet data stored in the first memory block 110 to read the index information for the switching select channel (step 408). At this time, the control block 108 generates a tuning control signal for tuning the broadcast signal of the switching channel and transmits it to the tuner and the demodulation block 102 through the line L11, and as a result, the tuner and the demodulation block 102 are selected and switched. The broadcast signal of the channel is tuned, and the video signal separated from the broadcast signal of the tuned selection channel thus tuned is transferred to the video synthesis block 118 through the MPEG decoding block 104 and the video encoding block 106.

In addition, the control block 108 extracts the call sign and logo data of the switching selection channel previously stored in the second and third memory blocks 112 and 114 based on the index information of the switching selection channel read out, and then menus through the line L17. Forward to generation block 116 (step 410). At this time, the control block 108 generates a screen configuration control signal for synthesizing the video signal of the switching selection channel on the line L16 on the line L19 and the banner screen data on the line L18.

Accordingly, the menu generation block 116 constructs banner screen data including the call sign and the logo of the switching selection channel, and transmits the banner screen data to the image synthesizing block 118 through the line L18 (step 412).

On the other hand, in the image synthesis block 118, in response to the screen configuration control signal provided from the control block 108 via the line L19, the analog video signal of the switching select channel provided from the video encoding block 106 via the line L16. And synthesized screen data obtained by synthesizing banner screen data (i.e., banner screen data including logo and call sign information of the switching selection channel) provided from the menu generating block 116 via line L18, that is, as shown in FIG. 5B as an example. As shown, the synthesized screen data including the banner area 56 and the video signal area 58 of the switching selection channel is transferred to the display side (not shown) (step 414).

As a result, on the monitor not shown, a banner screen as shown in FIG. 5B is displayed for a predetermined time (for example, 5 seconds, 10 seconds, etc.) as an example (steps 416 and 418). In this case, the banner area 56 on the displayed banner screen includes a logo display area 56a of the switching selection channel, a call sign display area 56b of the switching selection channel, and a program guide information display area 56c of the switching selection channel. .

On the other hand, in step 418, it is checked whether or not the current time t that counts the display time of the banner screen has reached a preset time n. If it is determined that t = n is not the result of the check, the process proceeds to step ( In step 416, the display of the banner screen is continued, and if it is determined that the current time t reaches the predetermined time n, the process proceeds to step 420, and in step 420, the present time is displayed on the monitor. After the banner screen being displayed is turned off, the broadcast program video signal of the switching selection channel is displayed on the monitor.

That is, when the channel is switched through the above-described process, a banner screen including the logo and call sign information of the switching selection channel is configured and displayed on the monitor, so that the user can display the logo and call sign of the switching selection channel displayed in this way. Through the information, it is possible to reliably recognize the channel name of the corresponding channel, and through this, the operation such as switching to another specific channel can be more smoothly performed.

As described above, according to the present invention, call sign and logo data of each channel are stored in advance in each satellite broadcasting receiver, and the broadcast signal transmission base station inserts and transmits the call sign and logo index information of each channel in the program guide packet, Program guide screen When there is a service request or channel switching request, a guide menu screen or banner screen including the call sign and logo data of the corresponding channel is drawn out based on the call sign and logo index information of the corresponding channel included in the program guide packet data.
