Description

Digital broadcast receiving apparatus

Technical Field

The present invention relates to a digital broadcast receiving apparatus, and more particularly, to a technique for displaying an electronic program table in a digital broadcast receiving apparatus.

Background

In a digital broadcast receiving apparatus for receiving digital television broadcasts, an electronic program table is created based on EPG (electronic program guide) information acquired from broadcast signals and displayed as an image on a screen. Then, the user can select a desired program from the electronic program table displayed as an image to view the program and reserve it for recording.

For example, a typical electronic program table is displayed as shown in fig. 12-19. Fig. 12 is a display of a converted prototype of an electronic program table. In fig. 12, the electronic program table 171 is configured to have a matrix display structure of time axis marks 173 and broadcast station axes (channel axes) 175 having broadcast stations arranged side by side when provided by the same program provider, and program information (program names in this example) corresponding to times and broadcast stations is displayed in program areas (e.g., 177-1 to 177-5) that are intersections of the aforementioned two axes. As can be seen from the screen of fig. 12, as shown in fig. 13, in the program area (indicated by hatching in the drawing, with emphasis placed on the program area XA-3) of the service ID 011(XA-2) in the broadcast station a (XA-1), program information (not shown) of a television series between 7 pm and 8 pm, for example, is displayed.

Note that in the drawings, a label such as XA-n indicates a region and a label such as 177-m indicates a program name or the like.

A detailed display area is provided at the edge of the electronic program table in which information on the focus program is also displayed in large characters. Making a configuration to display all programs with the service ID and time zone as minimum display units, so that in the area of the broadcasting station B where the focus is not set, for example, the program "Spring Travel" indicated overall by a symbol 177-0 is made to be displayed in the areas of the service IDs 021, 022 and 023, or different programs such as "Summer Travel" 177-1, "English Conversation" 177-3 and "French" 177-4 are displayed in each service ID; in addition, in the next time zone, for example, "Autumn Travel" 177-2, "EnglishConversation" 177-3, "Spanish Language" 177-5 is displayed; and in the still next time zone, the program "Winter Travel" indicated generally by the symbol 177-6 is displayed, for example, in the areas of the service IDs 021, 022 and 023.

In this case, when the focus is moved by the right cursor, as shown in fig. 14, the focus is placed on the broadcasting station B in which the area XA-6 of "autun Travel" 177-2 between 7 pm and 8 pm of the first service ID021 is focused. Further, when the focus is moved by the right cursor, as shown in fig. 15, the focus is still on the broadcast station B, in which the program area XA-8 of "English Conversation" between 7 pm and 8 pm of the second service ID022 is focused. Further, when the focus is moved by the right cursor, as shown in fig. 16, the focus remains on the broadcast station B with the program area XA-10 of "Spanish Language" between 7 pm and 8 pm of the third service ID023 being in focus. Further, when the focus is moved by the upper cursor, as shown in fig. 17, the focus remains on the broadcast station B, in which the program area XA-11 of "French Language" above "Spanish Language" between 7 pm and 8 pm of the third service ID023 is focused. Further, when the focus is moved by the upper cursor, as shown in fig. 18, the focus remains on the broadcast station B, in which the program area XA-10 of "Spring Travel" above "SummerTravel" between 6 pm and 7 pm of the first service ID021 is focused. Further, when the focus is moved by the lower cursor, as shown in fig. 19, the focus remains located on the broadcast station B, in which the program area XA-11 of "Summer Travel" below "Spring Travel" between 6 pm and 7 pm of the first service ID021 is focused. As such, a configuration is generally made to place the focus on the program existing in that direction as the cursor continues to move.

Problems to be solved by the invention

Incidentally, the EPG information includes so many programs provided by digital broadcasting that an electronic program table based on the EPG information makes a program display field correspondingly subdivided, thereby posing a problem that it is difficult to display all the electronic program information for browsing.

An object of the present invention is to improve operability in making reservations and selecting any one channel such as a representative channel and to increase the number of broadcast stations displayed on one screen of an electronic program guide without sacrificing browsability. Further, it is also an object to maintain operability of a cursor and compatibility of a display when all channels are displayed and when these channels are summarized and displayed.

Means for solving the problems

One broadcasting station is divided by the same provider, the same TS, and a combination thereof. An example of which includes a TS and a television channel of the same broadcast ID or the like. For example, NHK integration, NHK education, etc. are considered as one broadcasting station.

The present invention is characterized in that in a program table containing a representative channel predetermined in each TS and other channels, the following display control is performed.

(1) The display width of the representative channel is set to be significantly larger (not smaller than 1.5 times) than those of the channels other than the representative channel. In particular, channels other than the representative channel are configured such that a width within the limit of even one character, i.e., the size of the character of the input program unit, cannot be displayed.

(2) The display area of the channel other than the representative channel is located on one side (left or right side) of the representative channel so that each broadcasting station including the representative channel and the other channels other than the representative channel has a nearly uniform display width.

(3) In the above description, the width of the representative channel is set as follows.

In the above description, the cells other than the cell representing the channel have a width that allows determination of whether or not to place the cursor thereon, and when the cursor is not placed on the representative channel, the color configuration of the cell is realized by the same algorithm as the representative channel, and when the cursor is also placed thereon, the color configuration of the cell is realized with the same color as when the cursor is placed on the representative channel.

Advantages of the invention

According to the present invention, many broadcasting stations can be displayed in a browsable form within a limited display area of a display screen, as compared to a conventional program table. Further, one service in each broadcasting station may be configured as one large area of a program unit to have a channel width that can display program information such as a title.

Since the selected channels are arranged only in a large size, the positional relationship between the regions when the cursor is moved within one broadcast station is fixed, and an operation feeling compatible with a conventional display scheme in which the representative channel and the channels other than the representative channel have an equal display width can be produced while moving the cursor, thereby providing consistency in the user operation feeling.

Fixing the selected channel can move the cursor with the same sense as in the previous cursor movement while enabling the transition of the cursor from a localized structure (projected format) to a shared event.

Best mode for carrying out the invention

In the present invention, "TS" is an abbreviation for transport stream, which is specified in the MPEG System Standard (ISO/IEC 13818-1). The TS ID is an identifier assigned to each TS and unique in the network. The same TS indicates that the TS IDs are the same. In addition, a channel whose first number for distinguishing programs is "1" is considered as a representative channel.

For example, the representative channel is defined by a TS information descriptor in an NIT (network information table) included in the terrestrial digital broadcasting. It represents the main service determined by the manufacturer in the case of BS and CS. The display technique of the electronic program table associated with the present invention is characterized in that a plurality of frames are created and configured so that a display area defined by a display frame representing a channel other than a channel is smaller than a display area defined by a display frame representing a channel (which basically means any one channel in one broadcasting station or a channel having a minimum or maximum service ID in one broadcasting station). Hereinafter, a digital broadcast receiving apparatus according to one embodiment of the present invention is described with reference to the accompanying drawings. Fig. 1 and 2 respectively show an overview of a digital broadcast receiving apparatus according to the present embodiment.

As shown in fig. 1, the digital broadcast receiving apparatus a includes an antenna 1, a digital broadcast receiving unit 3 having a digital broadcast tuner, an electronic program table generating unit 5, a decoder, a remote controller light receiving unit 15, a voice signal processing unit 25 for performing voice signal processing, a speaker 21 for outputting voice based on a voice signal after processing, an image signal processing unit 27 for processing an image signal, a display 23 for outputting an image based on an image signal after processing, a control unit (CPU)7 for controlling each functional block through a bus BL1, and storage units (ROM and RAM)18 and 19 for storing programs and other information for performing processing described below. The control unit 7 includes, for example, an electronic program table editing unit 7a that performs processing based on a program.

As shown in fig. 2, a DVD (HDD) recorder (recording/reproducing apparatus) B includes an antenna 41, a digital tuner 43, a control unit 47, a remote controller light-receiving unit 51, a storage unit (HDD)53, an HDMI interface unit 55, an electronic program table acquisition unit 57, an optical disk drive unit 63 such as a DVD, and an operation unit 67. The control unit 47 is provided with an electronic program table editing unit 47a operable by a program. Each of which is operable by a respective remote control.

Although the electronic program guide may be used in any apparatus, for example, if the apparatus is compatible with the HDMI standard, the electronic program guide may be displayed on the display 23 by connecting both through HDMI and using any remote control device. The program information for forming the electronic program table may be extracted from the broadcast waves received by the above-described digital broadcast receiving unit, or may be acquired separately from the internet or the like.

Next, the editing process of the electronic program table is described based on the flowchart shown in fig. 3. Fig. 4 shows a display example of an electronic program table edited and displayed on a display based on the editing process of the electronic program table of the present embodiment. First, in step S1, a request for EPG display is made by the user using operation buttons of a remote control device or the like. Next, at step S2, it is determined whether the display request is made in a mode in which the program frame of the representative channel is displayed only in a large size when the representative channel exists or in a mode in which the program frame is displayed in the same size regardless of whether the channel is the representative channel. When it is not the mode in which only the program frame representing the channel is displayed in a large size (no), the process proceeds to step S3. A display example of the conventional display mode processing based on step S3 has been described above with reference to fig. 12 to 19. When it is the mode of displaying only the program frame representing the channel in a large size (yes), the procedure proceeds to step S4 and acquires information of all services displayed for each broadcasting station divided by the same provider, the same TS, and a combination thereof from the electronic program table information, and in step S5, calculation processing is performed on the allocation unit. Next, in step S6, a display frame to be allocated is created based on the calculation. At step S7, a determination is made from the processing of step S6 as to whether there is any event sharing, and when there is any event sharing (yes), at step S8, the programs to be shared are integrated and displayed without changing their widths. When there is no event sharing (no), the programs are displayed as such without being integrated at step S9. Television channels in one TS and having the same broadcast ID are basically configured to have the same width regardless of the number of services in the TS.

Next, one example of the calculation processing executed by the calculation unit in step S5 is described.

Basic calculation equation

(display width of representative channel) — (display width of one broadcast station) - (width of one channel other than representative channel) × (number of channels of one broadcast station) -1)

First example

When the number of channels including one broadcasting station representing a channel is 3, the display width of one broadcasting station is 10 (arbitrary unit), and the channel width of a channel other than the representing channel is 1 (same unit), the width of the representing channel is determined as follows:

(width of representative channel) 10- (1 × (3-1)) -10-2 ═ 8

Second example

When the number of channels including a broadcasting station representing a channel is 2, the display width of one broadcasting station is 10 (arbitrary unit), and the channel width of other channels than the representing channel is 1 (same unit), the width of the representing channel is determined as follows:

(width of representative channel) 10- (1 × (2-1)) -10-1 ═ 9

As can be seen from these equations, the width in the channel axis direction is fixed for all services displayed by each broadcasting station having the same TS and the same provider. The width of the representative channel is configured to be significantly larger than the widths of the other channels. The width is such that the former is a width level at which the displayed program name can be satisfactorily obtained, and the latter is a wide distribution level at which it is difficult to display the program name. This will be explained in connection with fig. 4. As shown in fig. 4, the display X of the electronic program table according to the present embodiment includes, for example, a matrix-shaped arrangement 71 having a time axis 73 as a vertical axis and a channel axis 75 (an axis dividing each broadcasting station) as a horizontal axis.

In comparison with the conventional configuration, fig. 4 is contrasted with fig. 12, and in the display example shown in fig. 12, when three different programs are played on service channels 021, 022, and 023 of broadcasting station B in a total of two hours of a period between 6 pm and 7 pm and a period between 7 pm and 8 pm of the same broadcasting station B, information on the three different programs of 021, 022, and 023 is respectively displayed using a uniform display frame for the three services in the program display frame of one broadcasting station B as shown in 177-1 to 177-5. In this case, the width of one broadcasting station is proportional to the number of services.

In contrast, in the display example shown in fig. 4, among three different programs between 6 pm and 7 pm and between 7 pm and 8 pm of the broadcast station B, the channel 021 as the representative channel is assigned with widths (77-3 and 77-4) of 8 with respect to the entire width 10 of the broadcast station B, and the channels 022(77-6) and 023(77-7) are assigned widths of 1 with respect to the entire width 10 of the broadcast station B, respectively. The frame dividing each channel is fixed. It is preferable to display the program information to be displayed in the frame (in the cell) only for the representative channel having a sufficient area, and not to display the program information for the other areas.

In addition, in order to make the existence of the narrow region conspicuous, the visibility of the narrow region at the time of recognition can be improved by color-coding the narrow region only with a primary color or the like, using a color code, adding hatching thereto, adding a unique mark thereto, or the like. In the case of the representative channel, and when the cursor is not placed in the narrow area, the color configuration of the cells of the narrow area is performed by the same algorithm as that of the representative channel, and even when the cursor is placed thereon, the color configuration of the cells can be performed on the narrow area by the same color as that of the representative channel on which the cursor is placed.

In this manner, fixing the allocation width of each broadcast station in the channel axis direction allows the allocation width in the channel axis direction of each broadcast station to be determined in advance so that the frame for dividing channels is not displaced each time the cursor is moved in the horizontal direction and thus easily seen, and then performing the above calculation based on the number of channels allows the allocation of program display frames to be determined in advance for programs in the same broadcast station. Since the programs can be displayed integrally based on the judgment later when there is any event sharing, a quick display can be realized. In addition, displaying an electronic program table by a predetermined program table frame allows a viewer to quickly recognize the possibility that a plurality of different programs exist within the same time zone with respect to each broadcasting station. Note that the predetermined advantage of performing the configuration of the program display frames in the same broadcast station in ascending order from a smaller number in the channel axis direction is: this is easy for the user to identify, since the display is made in a fixed configuration. In addition, the width in the channel axis direction can be reduced and information associated with more broadcasting stations can be displayed on the display, which is advantageous in improving the viewability of electronic programs, compared to the configuration shown in fig. 12. Returning to fig. 3, in step S10, a determination is made as to whether or not to set the focus on any program display field. When it is determined that the focus is set (yes), the process proceeds to step S11, and the details of the program at which the focus is located are displayed in the detailed display field 81 located at the edge of the large-sized program display field in an enlarged scale. Finally, the editing/display processing of the electronic program table is ended (step S12).

Hereinafter, a display example when the region where the focus is located is moved is described. As shown in fig. 5, "broadcast station a", channel "011", "drama" and "7:00 pm-8:00 pm" are displayed in the detailed display field 81 when the focus is located in the program display area A1 corresponding to between 7 pm and 8 pm of the broadcast station a in the electronic program table 71 shown in fig. 4, and the browsing operation can be advanced or the image recording can be started or reserved by the user.

Next, upon performing an operation of moving the focus with the right cursor, a configuration is made such that the focus is located on the 021 channel (also representative channel in this case) of the lowest channel number in the programs of the broadcasting station B that is between 7 pm and 8 pm in the same time zone as fig. 5 and that is on the right side of the broadcasting station a. When dividing the time sequence, a configuration is made such that the focus is located on "autun travel" in the area a2, which is a program area whose start time is close to 7:00 "theater". The advantages that exist in this case are: since the frame itself of the broadcasting station B is not changed, the visual recognition thereof is easy for the user and reduces eye strain, and in addition, since the movement of the focus area when the horizontal cursor is moved is in the same direction as the cursor operation direction, there is no deviation between the user operation and the cursor movement direction, and the cognitive load of the user is low. Of course, detailed information about "autun travel" is displayed in the detailed display area 81. Next, when operated by the right cursor from the display of fig. 6, the focus is located on the area A3 on the right side of the area a2 shown in fig. 7. By viewing the detailed area 81, it can be seen that the program is "English conversation" of the 022 channel of the broadcasting station B, and the broadcast time thereof is 6:30 to 7:30 in the afternoon. In this case, even if the same information is not displayed in the area a3 in the program display area, it is displayed in the detailed display area 81 and thus is easily understood by the user. This has the advantage of being relatively easy to read, since there are few display switches.

When the right cursor is further used from the display of fig. 7, the program from 7 pm is displayed in the area a4 shown in fig. 8. The reason why the focus is not located at the program starting from 6:30 but at the program starting from 7:00 in this case is that the focus has been located at the program starting from 7:00 two steps earlier than in fig. 6. In this manner, when a region over time is selected, which region the focus is to be placed in is determined with reference to the previous display state. Therefore, when the right cursor is continuously operated, the time zone of the previously set focus is stored so that the focused time zone in a series of operations remains the same. The same process can be performed for the left cursor case.

As shown in fig. 9, when an operation by the upper cursor is performed from fig. 8, the focus is located in an area a5 of the immediately preceding program in the same program 023. Further, when an operation is performed by the upper cursor, as shown in fig. 10, the focus is located on a program "Spring travel", which is a program 021 in the closest preceding time zone of the same broadcasting station B over the entire width of the channel axis of the broadcasting station B as shown in a region a 6. Next, when the operation of the down cursor is performed, as shown in fig. 11, the focus is located on an area a7 of the program 021 that is the closest subsequent program. In this case, it is configured such that the focus is located on the program corresponding to the program of the immediately preceding channel.

As described earlier, in the present embodiment, a configuration is made such that the display areas of the broadcast stations including the representative channel and the channels other than the representative channel have the same width, and that the channel with event sharing and the channel without event sharing, which is one service in one broadcast station, have the same width.

It is also possible to configure such that the display mode represented in the display example described in the present embodiment and the conventional independent display mode (for example, a scheme in which the representative channel and the channel other than the representative channel are displayed with the same width, and a scheme in which only the representative channel is displayed) can be switched by menu and key. In this case, it may be configured such that any one of the above-described display modes is selected by a menu operation or the like independently (individually) only for a specific broadcasting station designated by the user or collectively for all broadcasting stations.

In addition, the display mode as described above may be configured independently for each network (e.g., terrestrial digital network, CS digital network, and BS digital network), and may be configured collectively for each network. For example, the configuration may be such that only the terrestrial digital broadcasting is caused to adopt the display mode according to the present embodiment. The network may be configured to adopt the display mode together, or the display mode may be set independently for each broadcasting station through a menu.

In addition, the above configuration can be adopted collectively for each medium (television service, radio service, and data service). For example, only television services may employ the above configuration.

It is to be noted that when the number of display stations in one area is small as in terrestrial digital broadcasting, channels other than representative channels are displayed within a browsable range as necessary. In that case, it is preferable to preferentially display in a browsing form a broadcasting station that performs multi-channel broadcasting of a structure without event sharing, for example. When a limited configuration is implemented, it is preferable to display the service number where the cursor is located or highlight in the area where the broadcast station logo is to be displayed, so that the selected channel in the broadcast station is highlighted and easily seen. It is to be noted that when the one-touch button is displayed or the one-touch key is not assigned to the key service, an icon button indicating the one-touch key may be activated or grayed down so as not to be highlighted.

It is to be noted that, although the description has been made in the above example on the case where the representative channel is displayed in a larger size, the case where an arbitrary channel is selected and the display frame of the arbitrary channel is made larger is not excluded. Any channel designated by the user may be a representative channel. Accordingly, these cases are included in the scope of the present invention. Further, the EPG display may be an EPG display in which the time axis and the channel axis are replaced with each other.

In addition, since the digital broadcast receiving apparatus includes a television receiving apparatus, a recording/reproducing apparatus, a personal computer, and the like, the name and form of the product do not limit the present invention.
