Referring to FIG. 4, the control unit 170 obtains viewing history information about a plurality of preference programs or channels (S700). For instance, the control unit 170 obtains information about the programs and/or channels previously viewed by the user(s) or played at the image display apparatus 100. In one variation, the control unit 170 may collect such viewing history information for each different user, e.g., by associating each program/channel viewed by a specific user which may be done, e.g., by requesting a user to enter their user information prior to viewing the program/channel.
The plurality of preference programs may be content programs provided by a content provider or a broadcast channel program, or may be any content being viewed by the user. The plurality of preference channels may be channels provided by a content provider or carrying the broadcast programs. Viewing history information about watched time or the like and specific codes (text codes) for the type, the title, the viewing time, the viewing time zone or the like regarding a plurality of preference programs, for example, broadcast programs being viewed from the program guide information in a case of viewing the broadcast program are stored in storage unit 140, and such storing is can be repeatedly performed each time the user views any broadcast programs.
Next, after the storage operation is performed over a period of time, the control unit 170 classifies the collected viewing history over a period of time, and analyzes the stored broadcast program/channel information viewed/displayed up to now and viewing pattern information or the like through the recorded viewing time zone and viewing time based on any one of for each day of the week and each time zone. Herein, the period of time may be changed to years, months, weeks, days, etc. according to the user' settings.
Meanwhile, as mentioned above, the viewing history information may be obtained for each different individual viewer and in order to obtain the viewing history information for each individual viewer, the viewers may log in for each individual viewer when turning on the image display apparatus.
Next, the control unit 170 generates priority information about a plurality of preference programs or channels based on the viewing history information. The priority information may be calculated on the basis of any one of viewing time, the number of times of viewing, last viewing time of the viewing history information.
For example, when the period of time is set to one week, if viewing time of 6-channel (Channel 6), 7-channel (Channel 7) and 11-channel (Channel 11) is 23 hours, 18 hours, and 11 hours, respectively, for a week, the 6-channel, 7-channel, and 11-channel sequentially have the first to third priority and such priority information is stored in the storage unit 140.
As another example, if 6-channel, 7-channel and 11-channel were watched about six hours ago, about two hours ago and about eight hours ago, respectively, based on the current time, the 7-channel, 6-channel, and 11-channel sequentially have the first to third priority and such priority information is stored in the storage unit 140.
Meanwhile, the priority information may be calculated by combining two or more information of viewing time, the number of times of viewing, last viewing time of the viewing history information. Herein, each of the two or more information of the viewing history information may be weighted and the priority information is calculated, and the weights may be changed depending on the user's settings.
For example, when the weight of the viewing time is set to 1 and the weight of the number of times of viewing is set to 1.5, then if, for a week, the viewing time of 6-channel is 23 hours and the number of viewing is 10 times, the viewing time of 7-channel is 18 hours and the number of viewing is 20 times and the viewing time of 11-channel is 11 hours and the number of viewing is 4 times, the priority score of 6-channel is calculated to be 23*1+10*1.5=38, the priority score of 7-channel is calculated to be 18*1+20*1.5=48, and the priority score of 11-channel is calculated to be 11*1+4*1.5=17, according to the set weight information.
According to the calculated priority scores, the priority information may be calculated such that the 7-channel, 6-channel and 11-channel are ranked to have the first priority, the second priority and the third priority, respectively, and the determined priority information may be stored in the storage unit 140. Meanwhile, the priority information may be calculated by separating for at least one of each day of the week, each time zone, each genre, etc.
When the control unit 170 receives a channel browser entry command through the user input interface unit 150, the control unit 170 visually indicates a plurality of items indicating each of program/channel information to be distinct from each other according to the priority information generated, on a screen of the display unit 180 (S720).
The visually indicating step (S720), which may be provided by various methods, will be described below in more detail with reference to FIGS. 5 to 11. In the examples of FIGS. 5-11, different shapes, colors and configurations for each of the items are possible. For instance, although a circular item 810 is displayed in FIG. 5, the item 810 can have a different shape such as a square, rectangle or oval. In the examples of the present invention, at least one of different shapes, sizes, configurations, colors, fonts, icons, symbols, patterns, texts, etc. may be used to visually display the items indicating programs/channels differently from each other to reflect the different priorities of such items, so that the user can visually recognize the priorities of such items.
Referring to FIG. 5, a plurality of items 810, 820, 830 each representing one of a plurality of preference items may be visually indicated to be distinct from each other by varying the size of each item 810, 820, 830 according to the priority information.
First, the plurality of items 810, 820, 830 each representing one of the plurality of preference programs or channels are displayed on the display unit 180. Herein, the first item 810, the second item 820 and the third item 830 may be items representing 6-channel, 11-channel and 7-channel, respectively.
Each of the items 810, 820, 830 may display one of ions 811, 821, 831 each indicating broadcast channel information or content provider information representing each of the programs. For example, the first item 810 is an item representing 6-channel, and an icon 811, showing that the content provider providing the program(s) corresponding to 6-channel is for example SBS, may be indicated on or near the first item 810. In this example, SBS, tvN and KBS are mere examples of channel stations.
Meanwhile, each of the items 810, 820, 830 can indicate a representative thumbnail image 812, 822, 832 corresponding to each of programs or channels. For example, the first item 810 is an item representing 6-channel, and thus the representative thumbnail image 812 representing a program corresponding to 6-channel is indicated on the first item 810.
As mentioned above, the icons 811, 821, 831 and the representative thumbnail images 812, 822, 832 representing the broadcast channel information or content provider information are indicated on or near the items 810, 820, 830, respectively. Accordingly, the user can intuitively recognize by viewing the items 810, 820, 830 which program/channel each item represents.
According to the present invention, the plurality of items 810, 820, 830 are visually indicated to be distinct from each other based on the priority information. As shown in FIG. 5, a high priority item among the plurality of items may be largely indicated than a lower priority item among the plurality of items.
For example, assume that the first item 810 representing 6-channel has been ranked to have a first priority based on the calculated priority information (S710), the second item 820 representing 11-channel has been ranked to have a third priority based on the calculated priority information, and the third item 830 representing 7-channel has been ranked to have a second priority based on the calculated priority information.
Then such priority of each channel (or program in another example) may be visually indicated to the user by varying the size of the corresponding item being displayed to the user according to the priority. For instance, in the above example, the size of the first item 810 is displayed to be the largest since it has the first priority (highest priority), the size of the third item 830 is displayed to be less than that of the first item 810 since it has the second priority lower than the first priority, and the size of the second item 820 is less than that of the third item 830 since it has the third priority lower than the second priority. Accordingly, each of the items can be visually indicated to be distinct from each other to correspond with the priority information.
Herein, in each of the items 810, 820, 830, the size thereof may be determined in proportion to the priority scores. In addition, the sizes of the icons 811, 821, 831 and representative thumbnail images 812, 822, 832 included in each of the items 810, 820, 830 may be also determined In proportion to the sizes of each of the items 810, 820, 830.
In another example, referring to FIG. 6, a plurality of items 910, 920, 930 representing a plurality of preference programs or channels may be visually indicated to be distinct from each other by varying the number of specific marks displayed therewith.
First, the plurality of items 910, 920, 930 each representing one or more of the plurality of preference programs or channels are displayed on the display unit 180. Herein, the first item 910, the second item 920 and the third item 930 may be items representing 6-channel, 11-channel and 7-channel, respectively.
Each of the items 910, 920, 930 may indicate one of ions 911, 921, 931 indicating broadcast channel information or content provider information representing each of the programs/channels. For example, the first item 910 is an item representing 6-channel, and an icon 911, showing that the content provider providing the program corresponding to 6-channel is SBS, may be indicated on or near the first item 910.
Each of the items 910, 920, 930 can further include representative thumbnail image 912, 922, 932 corresponding to each of programs/channels. For example, the first item 910 is an item representing 6-channel, and the representative thumbnail image 912 representing a program corresponding to 6-channel may be displayed on or near the first item 910.
Meanwhile, the plurality of items 910, 920, 930 are visually indicated to be distinct from each other based on their priority information and at least one or more of specific marks are indicated on or in association with each of the plurality of items to reflect such priority information. For instance, the number of the specific marks indicated on the high priority item among the plurality of items may be largely indicated than the number of the specific marks indicated on the lower priority item, as shown in FIG. 6.
For example, assume that the first item 910 representing 6-channel has been ranked to have the first priority based on the calculated priority information, the second item 920 representing 11-channel has been ranked to have the second priority based on the calculated priority information, and the third item 930 representing 7-channel has been ranked to have the third priority based on the calculated priority information.
In this case, based on the calculated priority, a specific mark indicated on a specific area 913 of the first item 910 is display with 4 stars, a specific mark indicated on a specific area 923 of the second item 920 is display with 3 stars and the a specific mark indicated on a specific area 933 of the third item 930 is displayed with 1 star. Accordingly, each of the items 910, 920, 930 can be visually indicated to be distinct from each other according to their priority information.
Herein, the number of the specific marks included in each of the items 910, 920, 930 may be determined in proportion to the priority scores. As a result, the user can view the number of stars displayed for each item representing a program/channel and thereby recognize the priority of that program/channel in comparison with other items displayed on the screen. Here, the use of stars is merely an example, and any specific mark can be used to reflect the priorities.
In another example, referring to FIG. 7, a plurality of items 1010, 1020, 1030 representing a plurality of preference programs/channels are indicated by overlapping with each other, and the high priority item of the plurality of items may be indicated to be arranged on the front or the center relatively compared with the lower priority items to visually indicate the priorities of these items.
First, the plurality of items 1010, 1020, 1030 representing the plurality of preference programs or channels are displayed on the display unit 180. Herein, the first item 1010, the second item 1020 and the third item 1030 may be items representing 6-channel, 11-channel and 7-channel, respectively.
Each of the items 1010, 1020, 1030 may indicate one of icons 1011, 1021, 1031 indicating broadcast channel information or content provider information representing each of the programs or channels. Meanwhile, each of items 1010, 1020, 1030 can indicate a representative thumbnail image 1012, 1022, 1032 corresponding to each of programs/channels. For example, the first item 1010 is an item representing 6-channel, and the representative thumbnail image 1012 representing a program corresponding to 6-channel may be indicated on or near the first item 1010.
The plurality of items 1010, 1020, 1030 are visually indicated to be distinct from each other according to their priority information, by overlapping and arranging the plurality of items 1010, 1020, 1030 according to their priority. For instance, the high priority item of the plurality of items may be indicated to be arranged on the front or the center relatively compared with the lower priority item, as shown in FIG. 7.
For example, assume that the first item 1010 representing 6-channel (SBS) has been ranked to have the second priority based on the calculated priority information, the second item 1020 representing 11-channel (tvN) has been ranked to have the first priority based on the calculated priority information, and the third item 1030 representing 7-channel (KBS) has been ranked to have the third priority based on the calculated priority information.
In this case, the first item 1010, the second item 1020 and the third item 1030 are displayed to be overlapped with each other, where the second item 1020 which has the first priority according to the priority may be indicated to be arranged on the forefront or the center relatively compared with the first item 1010 and the third item 1030 have less priority. Herein, further, in each of the items 1010, 1020, 1030, the size thereof may be determined in proportion to the priority scores. In addition, the sizes of the icons 1011, 1021, 1031 and representative thumbnail images 1012, 1022, 1032 included in or near each of the items 1010, 1020, 1030 may be also determined in proportion to the sizes of each of the items 1010, 1020, 1030.
Further, since the items regarding the program/channel information are arranged to be overlapped, much more information may be displayed on the channel browser screen. In addition, since it allows the user to view the items in a three-dimensional structure, the user can intuitively feel the priority information of the program due to the three-dimensional perspective.
Meanwhile, each of the plurality of items 810, 820, 830 may further include a section thumbnail image in addition to the representative thumbnail image, which will be described with reference to FIG. 8 in detail. The concept of FIG. 8 can be applied to any of the methods discussed above including the methods of FIGS. 5-7. As an example only, however, the concept of FIG. 8 is discussed as being applied to the visual indication method of FIG. 5.
As shown in FIG. 8(a), the representative thumbnail images 812, 822, 832 corresponding to the programs or channels are visually indicated on each of the items 810, 820, 830 representing programs/channels displayed on the display unit 180. This is what was shown in FIG. 5.
As shown in FIG. 8(b), when the user locates a pointer 850 on or near any one of the plurality of items 810, 820, 830, then one or more section thumbnail images may be displayed. For example, if the user places the pointer 850 on the representative thumbnail image 812 indicated on the first item 810 through the user input interface unit 150, a plurality of section thumbnail images 840 of a program related to the representative thumbnail image 812 may be displayed on or near the first item 810.
Each section thumbnail image 840 may be a thumbnail image which represents each section divided when the entire section of the program related to the representative thumbnail image 812 is divided for each specific section. For instance, each section thumbnail image 840 may represent a thumbnail image of a section of a program or a portion of the program identified by the representative thumbnail image 812.
Further, the user may select one of the displayed section thumbnail images 840 to play that section of the program. For instance, after placing the pointer 850 on any one of the plurality of indicated section thumbnail images 840, if the user selects a specific section thumbnail image among the images 840 by using the pointer 850 or other means, the program may be reproduced and played from the section corresponding to the selected section thumbnail image.
Meanwhile, each of the plurality of items 810, 820, 830 may further include additional information regarding each corresponded program and/or channel, which will be described with reference to FIG. 9 in detail. The concept of FIG. 9 can be applied to any of the methods discussed above including the methods of FIGS. 5-8. As an example only, however, the concept of FIG. 9 is discussed as being applied to the visual indication method of FIG. 5.
As shown in FIG. 9(a), the plurality of items 810, 820, 830 are indicated, and the icons 811 821 831 representing the broadcast channel information or content provider information are indicated on each of the items 810, 820, 830 as also shown in FIG. 5.
As shown in FIG. 9(b), when the user locates a pointer 850 on or near any one of the plurality of items 810, 820, 830, additional information about the selected program or channel may be displayed, e.g., as a pop-up or in some other manner. For example, if the user places the pointer 850 on the icon 811 (or selects the icon 811 using the pointer 850) representing the broadcast channel information or content provider information indicated on the first item 810 through the user input interface unit 150, additional information about the program and/or channel corresponding to the first item 810 may be indicated through a predetermined pop-up window 860.
The additional information indicated through the pop-up window 860 or through other manner on the screen may include at least one of channel information, genre information, title information and broadcast time information about the program/channel, and/or content provider information.
Meanwhile, the method of visually indicating the plurality items information to be distinct from each other based on the priority information may be indicated to be arranged on the basis of at least one of each day of the week and each time zone, and the explanation will be described with reference to FIG. 10 in detail. The concept of FIG. 10 can be applied to any of the methods discussed above including the methods of FIGS. 5-9. As an example only, however, the concept of FIG. 10 is discussed as being applied to the visual indication method of FIG. 5.
Referring to FIG. 10, a plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 each representing one or more of a plurality of preference programs and/or channels may be visually indicated to be distinct from each other by varying the sizes of these items according to their calculated priority information. Further, such items are organized and arranged for each day of the week and each time zone in a day.
The channel browser included in the display unit 180 may be displayed with a tap 1120 delimited by each day of the week and/or a tap 1130 delimited by each time zone. By selecting the day and/or time tap among the taps 1120 and 1130, the user can display various items corresponding to the day and/or time of the selected tap(s) while their different priority information is also visually indicated as discussed above.
When the user selects a Mon tap corresponding to “Monday” among the taps 1120 delimited by each day of the week through an input of the user input interface unit 150, the plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 are visually indicated on the display unit 180 to be distinct from each other according to the priority information calculated based on the viewing history information for all Mondays. In addition, the plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 can calculate the priority information by delimiting the viewing history information corresponding to all Mondays for each time zone.
For instance, the control unit of the image display apparatus 100 may determine that the channels/programs corresponding to the first to third items 1111, 1112, 1113 among the items are most viewed on Mondays from 6:00 to 12:00 (time zone) based on the collected viewing history information during that time. If so, the control unit determines the size of the first to third items 1111, 1112, 1113 according to their calculated priority information and then displays the first to third items 1111, 1112, 1113 according to the determined sizes under this time zone on the display unit 180.
In addition, the control unit may determine that the channels/programs corresponding to the forth to sixth items 1114, 1115, 1116 among the plurality of items are most viewed on Mondays from 12:00:00 to 18:00 time. If so, the control unit determines the size of the forth to sixth items 1114, 1115, 1116 according to their calculated priority information and then displays the forth to sixth items 1114, 1115, 1116 according to the determined sizes under this time zone on the display unit 180.
In addition, the control unit may determine that the programs/channels corresponding to the seventh to ninth items 1117, 1118, 1119 of the plurality of items are most viewed on Mondays during 18:00:00 to 24:00 time. If so, the control unit determines the size of the seventh to ninth items 1117, 1118, 1119 according to their calculated priority information and then displays the seventh to ninth items 1117, 1118, 1119 according to the determined sizes under this time zone on the display unit 180.
Herein, the setting of the time zone may be changed according to the user's setting. The items are displayed by dividing a day into three time zones in this example of the present invention, but the items may be displayed by dividing a day into any number of time zones, e.g., two to eight time zones. Further, the user can set and change the number of items that can be displayed per time zone and/or per day of the week. Moreover, the week can be divided into a weekend and a weekday, instead of seven separate days. Other variations are possible. In addition, the classifications of FIG. 10 (e.g., based on the day and/or time zone) may be done for each different user of the image display apparatus 100, or for only the favorite channels/programs designed by the user.
In another example, the method of visually indicating the plurality items to be distinct from each other based on their priority information may arrange the items on the basis of at least one of each day of the week and each genre, and the explanation thereof will be described with reference to FIG. 11 in detail. The concept of FIG. 11 can be applied to any of the methods discussed above including the methods of FIGS. 5-9. As an example only, however, the concept of FIG. 11 is discussed as being applied to the visual indication method of FIG. 5. The concepts of FIGS. 10 and 11 may be combined so that different taps for the day, time zone, and/or genre may be provided on a single screen for the user's selection.
Referring to FIG. 11, a plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 each representing one or more of a plurality of preference programs/channels may be visually indicated to be distinct from each other by varying the size thereof. These items are also arranged for each day of the week and each genre.
The channel browser included in the display unit 180 may be displayed with the tap 1120 delimited by each day of the week and a tap 1130 delimited by each genre.
When the user selects a Mon tap corresponding to Monday of the taps 1120 delimited by each day of the week through an input of the user input interface unit 150, the plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 are displayed to be visually distinct from each other by calculating their priority information based on the viewing history information corresponding to previous Mondays. In addition, the plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 are further classified according to each genre by delimiting the viewing history information corresponding to Mondays for each genre.
For instance, programs/channels corresponding to the first to third items 1111, 1112, 1113 of the plurality of items may be determined to have been most viewed on Mondays for the genre corresponding to sports. Then the control unit determines the sizes of the first to third items 1111, 1112, 1113 according to the calculated priority information and displays the first to third items 1111, 1112, 1113 according to the determined sizes under the sports genre on the display unit 180.
In addition, programs/channels corresponding to the forth to sixth items 1114, 1115, 1116 may be determined to have been most viewed based on the viewing history information of the genre corresponding to drama on Mondays. Then the control unit determines the sizes of the forth to sixth items 1114, 1115, 1116 according to their calculated priority information and displays the forth to sixth items 1114, 1115, 1116 according to the determined sizes under the drama genre on the display unit 180.
In addition, programs/channels corresponding to the seventh to ninth items 1117, 1118, 1119 of the plurality of items may be determined to have been most viewed based on the viewing history information of the genre corresponding to movies on Mondays. Then the control unit determines the sizes of the seventh to ninth items 1117, 1118, 1119 according to their calculated priority information and displays the seventh to ninth items 1117, 1118, 1119 according to the determined sizes under the movies genre on the display unit 180.
Herein, the setting of the genre may be changed according to the user's setting. The items are displayed by dividing the genre into three genres, but the items may be displayed by dividing the genre into any number of genres, more or less genres.
FIG. 12 is a flow chart showing a program information display method of an image display apparatus according to another embodiment of the present invention. FIG. 13 shows diagrams showing a method for visualizing and displaying the program information on a screen of the image display apparatus according to this embodiment of the present invention. The method of FIGS. 12-13 can be implemented by the image display apparatus 100 of FIG. 1 or 2.
Referring to FIG. 12, the control unit 170 obtains channel change information about a plurality of preference programs or channels previously viewed on the screen of the image display apparatus 100 (S1800).
Herein, the channel change history information may be information about a time in which signals about the channel change are input, a channel number of the input time, and a time section maintained for the channel number, based on signals about the channel change input through the user input interface unit 150 by the user.
Next, the user selects any one of the plurality of items displayed on the display unit 180 through the user input interface unit 150 to be distinct from each other according to the priority information using at least one of the methods discussed above (S1810).
The control unit 170 displays the channel change history on the display unit 180 on the basis of the selected items based on the channel change history information (S1820). Herein, the display of the channel change history may be performed by highlighting at least one item of changed channel on the basis of the selected items and displaying connection lines which connect the highlighted items each other. The connection lines can indicate the channel switching pattern of the user for the identified item. The concept of FIG. 12 can be applied to any of the methods discussed above including the methods of FIGS. 5-11. As an example only, however, the concept of FIG. 12 is discussed as being applied to the visual indication method of FIG. 10.
In one example, as shown in FIG. 13(a), the plurality of items 1111, 1112, 1113, 1114, 1115, 1116, 1117, 1118, 1119 each representing one or more of the plurality of preference programs/channels may be visually indicated on the display unit 180 to be distinct from each other by varying the size thereof according to their priority information. Such items may also be arranged for each day of the week and each time zone as shown in FIG. 10 previously.
