The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system operation library layer and obtain the services of the system in the execution process through the API interface, and call corresponding drivers in the kernel layer to drive corresponding modules to use corresponding resources to execute corresponding services.

When a user watches live programs through the display device 200, the user can grasp program information of programs played by each live channel in each playing time period, such as program names, playing time periods, program durations and the like, by browsing the electronic program guide EPG, so as to determine interesting programs, and watch the programs in the corresponding playing time periods, thereby improving the experience of watching the live programs by the user. The electronic program guide is shown in fig. 5, and includes a channel list and a presentation window. The channel list includes channel names of channels to be displayed, for example, channel a, the display window includes program display areas, each program display area is used for displaying a program name of a program, for example, program a1 corresponding to channel a, and the program name a1 is displayed in the corresponding program display area. As shown in fig. 5, the lengths of the program display areas are equal, where the channel a corresponds to the program a1, the program a2, and the program a3, and the channel B corresponds to the program B1, the program B2, and the program B3, and the lengths of the program display areas corresponding to the program a1, the program a2, the program a3, the program B1, the program B2, and the program B3 are all equal. Therefore, the dividing method of the program display area cannot display the broadcasting time period corresponding to each program, and cannot directly see the program duration corresponding to each program through the program display area. If the user needs to know the program duration and the broadcast time period of the program specifically, the control device 100 or the intelligent device 300 needs to be operated and controlled to select the program display area corresponding to the program so as to display the program duration and the broadcast time period of the program. Illustratively, the user needs to know detailed information of the program a1, move the focus to the program presentation area of the program a1 by manipulating the remote controller, and send a selection instruction to the display apparatus 200 to present the broadcast period of the program a1 on the presentation window, and the user needs to further calculate the program duration of the program a1 based on the broadcast period of the program a 1. As can be seen, the electronic program guide shown in fig. 5 cannot visually display the broadcast time interval and the program duration of the program played by each channel to be displayed, and requires a user to perform complicated operations and calculations to be able to grasp the program information of the program, which results in poor experience of the user.

In order to solve the above problem, the length of the program display area is used to reflect the program duration, i.e. the program duration is proportional to the length of the program display area, wherein the longer the program duration, the longer the length of the display area, the shorter the program duration, and the shorter the length of the display area. The electronic program guide may be displayed by referring to the flow shown in fig. 6, and the specific steps are as follows:

s601, receiving an instruction which is input by a user and indicates to display the electronic program list.

When a user watches a live program, if a demand for browsing an electronic program list is generated, an instruction may be sent to the display device 200 through the control device 100 or the smart device 300, so as to instruct to display the electronic program list.

S602, responding to the instruction, determining a first channel set based on the channel corresponding to the program picture, the channels in the pre-stored channel list and the preset channel display number, and determining a display time period based on the current time and the preset time period range.

In response to the instruction, the display device 200 generates a corresponding electronic program guide, where the electronic program guide includes a channel list and a display window, where the channel list is a first channel set composed of channels to be displayed, and the display window includes a plurality of program display areas for displaying program names of the programs.

The first channel set may be generated by referring to the flow shown in fig. 7, and the specific steps are as follows:

s701, determining an index of the channel in a pre-stored channel list based on the channel corresponding to the program picture and the pre-stored channel list.

In the present embodiment, the pre-stored channel list includes a plurality of channels, which are live channels pre-stored in the display apparatus 200. The channel corresponding to the program picture is a live channel on which the display device 200 is playing the program content. The preset channel display number (page size) refers to the maximum number of channels displayed in the channel list, that is, the pre-stored channel list is displayed in pages, each page displays one channel list, and each channel list only displays the corresponding number of channels in the pre-stored channel list. Exemplarily, if the pre-stored Channel list includes 4 channels, which are Channel (Channel)1 to Channel (Channel)4, in order to ensure the exhibition effect of the Channel name and the program exhibition area, the number of Channel exhibitions of the Channel list is limited, for example, the number of Channel exhibitions is 2, that is, the Channel list only shows 2 channels in the pre-stored Channel list at a time. Taking first in fig. 8 as an example, the first page of Channel list shows Channel names of Channel 1 to Channel 2, and taking second page of Channel list in fig. 8 as an example, shows Channel names of Channel 3 to Channel 4. The user may instruct the display apparatus 200 to display a channel list of a previous page or a channel list of a next page of the current channel list by a page turning key 801 as shown in fig. 8, or the user may instruct the display apparatus 200 to display a page of the current channel list by manipulating a page turning key on the remote controller.

Each channel in the pre-stored channel list has a corresponding index, and the corresponding channel can be determined based on the index. In some embodiments, the index may be a sequence number (index) of a Channel in a pre-stored Channel list, for example, the pre-stored Channel list includes Channel 1 to Channel 4, where the sequence number of Channel 1 is 1, and then the index corresponding to Channel 1 is 1; if the sequence number of Channel 2 is 2, the index corresponding to Channel 2 is 2.

After determining the Channel corresponding to the program picture, based on the pre-stored Channel list, the index corresponding to the Channel may be determined, for example, if the Channel corresponding to the program picture is determined to be Channel 1, based on the pre-stored Channel list, the corresponding index may be determined to be 1.

S702, determining the first channel set based on the index and the preset channel display number.

In some embodiments, the channel corresponding to the program picture is a first channel in the first set of channels. At this time, the rest channels in the first channel set are channels with the preset channel display number from the channel corresponding to the program picture in the pre-stored channel list. Exemplarily, the Channel corresponding to the program picture is Channel 2, and assuming that the preset Channel exhibition data is 2, the channels in the first Channel set are Channel 2 and Channel 3.

In some embodiments, the channel corresponding to the program picture is the nth (N > 1, and N is an integer) channel in the first channel set, and the first channel set may be determined by referring to the following process, which includes the following specific steps:

and determining each second channel set based on the pre-stored channel list and the preset channel display number.

Based on the pre-stored channel list and the preset channel showing number, the total page number of the channel list can be obtained, namely the total page number of the channel list is the ratio of the total number of the channels of the pre-stored channel list to the preset channel showing number, wherein if the ratio has a remainder, the total page number is the sum of an integer part of the ratio and 1. The channels in different channel lists are different, the number of pages corresponding to each channel list can be called a list page number, and the set of channels shown on each page is a second channel set. For example, the total number of pages of the Channel list corresponding to the pre-stored Channel list in fig. 8 is 2, the list page number corresponding to the Channel list in (r) in fig. 8 is 1, and the corresponding second Channel set is Channel 1 and Channel 2. In fig. 8, the list page number corresponding to the Channel list is 2, and the corresponding second Channel set is Channel 3 and Channel 4.

Determining the first set of channels based on the index, the first set of channels being the second set of channels where the index is located.

By calculating the ratio of the index of the current channel to the display number of the preset channel, the list page (current page) corresponding to the second channel set where the current channel is located can be determined. Illustratively, the list page number corresponding to the channel list satisfies the following formula:

where floor represents an integer number of the ratio. For example, taking the preset channel showing number as 2 as an example, if the index of the current channel is 1, the first channel set is the second channel set with the list page number of 1, and if the index of the current channel is 3, the first channel set is the second channel set with the list page number of 2.

In this embodiment, the index of the first channel (start index) in the first channel set in the pre-stored channel list satisfies the following formula:

start index＝(current page-1)*page size+1

the index of the last channel (end index) in the first set of channels in the pre-stored channel list satisfies the following formula:

end index＝current page*page size

for example, if the list page number corresponding to the first channel set is 2 and the channel showing number of the first channel set is 2, the index of the first channel in the first channel set in the pre-stored channel list is 3, and the index of the last channel in the first channel set in the pre-stored channel list is 4.

And acquiring the channels in the first channel set from the pre-stored channel list based on the indexes of the first channel and the last channel in the first channel set in the pre-stored channel list.

The index of each channel between the first channel and the last channel in the pre-stored channel list can be determined based on the indexes of the first channel and the last channel in the pre-stored channel list in the first channel set, and then the corresponding channel is obtained from the pre-stored channel list based on the indexes from the first channel to the last channel. For example, the index of the first Channel is 3, and the index of the last Channel is 4, then the indexes of the channels of the first Channel set in the pre-stored Channel list are 3 and 4, respectively, and thus based on the indexes of the channels, channels 3 to 4 can be obtained from the pre-stored Channel list.

It should be noted that, if the list page number of the first channel set is the last page, and the number of channels in the first channel set is less than the preset channel display number, the index of the last channel in the first channel set in the pre-stored channel list is still calculated according to the above process, and when a channel is acquired, only the existing channel is acquired.

Exemplarily, if the current Channel is Channel 1, a first page Channel list shown in (r) in fig. 8 is directly displayed; if the current Channel is Channel 3, the second page Channel list shown in (c) of fig. 8 is directly displayed. Therefore, the acquired channel to be displayed is the corresponding channel in the channel list where the current channel is located.

The display time period may be determined with reference to the flow shown in fig. 9, and the specific steps are as follows:

and S901, acquiring the current time and a preset time period range.

In the present embodiment, the current time refers to the system time when the display apparatus 200 receives an instruction (instruction to display an electronic program guide) transmitted by the user. Illustratively, if the display device 200 receives the instruction at 15:00:00, the current system time is 15:00: 00. The preset time period range refers to a time period to be displayed, and may be a time period range set by the display device 200 by default, or a time period range adjusted by the user in advance based on personal needs.

S902, determining a display time period based on the current time and the preset time period range, wherein the starting time of the display time period corresponds to the current time, and the ending time of the display time period corresponds to the ending time of the preset time period range.

In some embodiments, the preset time period range refers to the total duration of the period to be presented, and the presentation time period is determined based on the current time and the preset time period range, where the start time and the end time of the presentation time period may be determined according to the following examples:

for example, the current system time may be directly used as the starting time of the presentation time period, and the system time obtained by adding the current time to the preset time period range may be used as the ending time of the presentation time period. Illustratively, if the current time is 15:00:00 and the preset time period range is 2 hours, the starting time and the ending time of the presentation time period are 15:00:00 and 17:00:00 respectively.

In the second example, if the current time is not a whole point, that is, a value exists in the decimals and/or the seconds, the values of the current time in the decimals and the seconds can be ignored, the value in the time is used as the current time to be finally used, the current time to be finally used is used as the start time of the presentation time period, and the system time obtained by adding the current time to be finally used and the preset time period range is used as the end time of the presentation time period. As an example. The current time is 15:25:20, the current time of final use is 15:00:00, the preset time period range is 2 hours, the starting time of the display time period is 15:00:00, and the ending time of the display time period is 17:00: 00.

Therefore, when the current time is not the integral point, the starting time and the ending time of the display time period can be conveniently calculated by omitting the numerical values on the fraction bits and the second bits, and the efficiency of determining the display time period is effectively improved.

In example three, if the current time is not the whole point, the start time of the presentation time period may be determined by comparing the current time with a preset presentation time point. In this embodiment, the preset display time point is a designated system time, for example, an integer point of 1:00:00, 2:00:00, 3:00:00, etc. The time intervals between two adjacent preset display time points are equal, namely if the time interval is 1 hour, the preset display time points are 1:00:00, 2:00:00, 3:00:00 and the like, and if the time interval is 2 hours, the preset display time points are 1:00:00, 3:00:00, 5:00:00 and the like. The time interval may be a default time interval of the display device 200, or may be a time interval adjusted by the user based on personal needs, for example, if the duration of the program in the presentation time period is longer, a larger time interval may be used in an adjustment manner; if the program duration within the presentation time period is short, the use of the smaller time interval may be adjusted to improve the accuracy of the subsequent determination of the start time of the presentation time period based on the current time and the preset presentation time point.

In example three, the starting time of the presentation time period may be determined with reference to the flow shown in fig. 10, and the specific steps are as follows:

s1001, obtaining preset display time points, wherein the preset display time points are appointed system time, and time intervals between every two adjacent preset display time points are equal.

The display device 200 obtains the pre-stored presentation time point from the memory, and the setting manner of the pre-stored presentation time point may refer to the description in example three, which is not described herein again.

S1002, obtaining the time distance between the current time and the preset display time point with the closest time distance.

By calculating the difference between the current time and each preset display time point, the time distance between the current time and each preset display time point can be obtained. For example, if the current time is 15:01:20 and the preset display time point is 15:00:00, the time distance between the two is 1 minute and 20 seconds. Thus, based on the time distance between the current time and each preset presentation time point, a preset presentation time point (for convenience of description, referred to as a target presentation time point) whose time distance is the closest may be determined. In some embodiments, to reduce the amount of calculation, a target presentation time period in which the current time is located may be determined based on the current time and each preset presentation time point, where the start time and the end time of the target presentation time period are two adjacent preset presentation time points, and at this time, the target presentation time point may be determined by only comparing the time distances between the current system time and the start time and the end time of the target presentation time period, respectively. Illustratively, the current time is 15:01:20, the target display time period is 15:00:00 (starting time) -16: 00:00 (ending time), the time distance between the current time and the starting time is 1 minute and 20 seconds, the time distance between the current time and the ending time is 58 minutes and 40 seconds, the target display time point is 15:00:00, and the time distance to be acquired is 1 minute and 20 seconds.

S1003, judging whether the time distance is smaller than or equal to a time threshold value.

S1004, if the time distance is less than or equal to the time threshold, taking the preset display time point with the closest time distance as the starting time of the display time period.

If the time distance is smaller than or equal to the time threshold, it is indicated that the time distance between the current time and the target preset display time point is relatively small, in order to facilitate calculation of the period to be displayed, the target preset display time point can be used as the starting time of the display time period, and the calculation efficiency of the end time in the display time period can be effectively improved based on the target preset display time point set at the whole point. Illustratively, the current time is 15:1:20, the target display time period is 15:00: 00-16: 00:00, the target display time point is 15:00:00, and if the time threshold is 5 minutes, the starting time of the display time period is 15:00: 00. If the preset time period range of the presentation time period is 2 hours, the end time of the presentation time period is 17:00: 00. Illustratively, the current time is 15:58:20, the target display time period is 15:00:00 to 16:00:00, the target display time point is 16:00:00, and if the time threshold is 5 minutes, the starting time of the display time period is 16:00: 00. If the preset time period range of the presentation time period is 2 hours, the end time of the presentation time period is 18:00: 00.

In some embodiments, the live channel tends to schedule a program to begin at an hour (which may occur coincident with a preset show time node), wherein if the last program ends but the hour at which the next program begins is not reached, the live channel schedules an advertisement for the hour, and so on. Therefore, by adopting the mode of determining the starting time in the display time period, the relatively useless program information such as programs and advertisements which are displayed and close to the end in the display time period can be effectively avoided. Moreover, the program duration corresponding to the part of the program is usually the remaining duration, rather than the complete program duration, and the remaining duration is relatively short, and if the program name is displayed in the display window, the length of the corresponding program display area is also short. By adopting the mode of determining the starting time in the display time period, the program display area with too short time can be effectively avoided, so that the display integrity of the program name is ensured.

S1005, if the time distance is larger than the time threshold, taking the current time as the starting time of the display time period.

If the time distance is greater than the time threshold, the time distance between the current time and the target preset display time point is larger, and in order to ensure the effective display of the currently played program, the current time is taken as the starting time of the display time period. Illustratively, the current time is 15:30:30, the target display time period is 15:00: 00-16: 00:00, the target display time point is 16:00:00, and if the time threshold is 5 minutes, the starting time of the display time period is 15:30: 30. If the preset duration of the presentation period is 2 hours, the end time of the presentation period is 17:30: 30.

In some embodiments, the live channel schedules the program to start at the whole time, and in order to facilitate the calculation of the presentation time period, the target presentation time point is used as the starting time of the presentation time period, and if the time distance between the current time and the target preset presentation time point is relatively large, that is, the currently played program has a relatively long remaining time, generally, the user tends to pay attention to such currently played program. In order to avoid the above problems, the current time is taken as the starting time of the display time period, so that effective display of the currently played program can be ensured.

In some embodiments, to facilitate the calculation of the presentation time period, the values in the second bits of the current time may be ignored, and only the values in the time bits and the fraction bits are used as the current time of the final use, and the current time of the final use is used as the start time of the presentation time period. Illustratively, the current time is 15:30:20, the current time of the final use is 15:30:00, and the start time of the presentation time period is 15:30: 00.

S603, determining the programs of the first channel set in the display time period.

After determining the first channel set and the presentation time period based on the above process, the display device 200 obtains program information of programs played by each channel in the first channel set in the presentation time period from the live broadcast signal, where the program information includes a program name, a program duration, a broadcast time period, and the like in this embodiment.

The number of programs played by the channel in the presentation time period is greater than or equal to 0, that is, No program is not played by the channel in the presentation time period, or at least one played program exists in the presentation time period.

The display area (e.g., channel list, display window, etc.) in the electronic program guide has a preset size, which may be a default design size of the display device 200 or a size that is preset by the user based on personal needs. When the electronic program guide is generated, each presentation area is generated based on these preset sizes. The display time period can be displayed at the top of the display window, each program display area is displayed below the display time period, and the vertical mapping of the display position of the program display area on the display time period is consistent with the broadcasting time period of the corresponding program of the program display area. Therefore, the broadcasting time interval of the programs broadcasted by each channel can use the same presentation time interval as the display reference. The display time period also corresponds to a preset size, namely the preset length of the display window.

The length of the program display area may be determined by referring to the flow shown in fig. 11, and the specific steps are as follows:

s1101, acquiring the preset length of the display window.

S1102, determining the length of a program display area corresponding to the program based on the duration of the display time period, the preset length of the display window and the program duration of the program.

The ratio of the duration (width duration) of the display time period to the preset length (width) of the display window is consistent with the ratio of the program duration (program duration) of the program to the length (program width) of the program display area corresponding to the program. Based on the ratio, the length of the program display area can be calculated, and the length of the program display area satisfies the following formula:

illustratively, the duration of the program is 1 hour, the duration of the presentation time period is 3 hours, and the preset length of the presentation window is 30, then the length of the program presentation area is 10.

The height of the program presentation area corresponds to the height of the channel in the channel list on which the program of the presentation area is broadcast. Illustratively, if the height of the channel in the channel list is 5, the height of the program display area corresponding to the program played by the channel is also 5.

S604, displaying an electronic program list, wherein the electronic program list comprises the first channel set and a display window, the display window comprises a plurality of program display areas, and the program display areas are used for displaying program names of programs of the first channel set in the display time period.

The channel names of the channels in the first channel set are arranged according to their indexes in the pre-stored channel list, resulting in a channel list, as shown in fig. 8.

Displaying each program display area at a corresponding position in the display window under the display time period, and displaying the program name of the corresponding program in the program display area, wherein each display area can be arranged by referring to the following procedures:

and acquiring the sequence of all programs played by the channel to be displayed in the time period to be displayed.

And acquiring the broadcasting time interval of each program played by the channel to be displayed in the time interval to be displayed, and obtaining the sequence of all the programs based on the broadcasting time interval of each program. Illustratively, the Channel 7 to be shown includes programs xxx, xxx and xx played in the time period 15:00: 00-17: 00:00 to be shown, wherein the playing time period of the program xxx is 15:00: 00-15: 30:00, the playing time period of the program xxx is 15:30: 00-16: 00:00, and the playing time period of the program xx is 16:00: 00-17: 00: 00. Thus, the program xxx, and x are ordered so that program xxx is broadcast first, program xxx is broadcast second, and program x is broadcast last.

And correspondingly displaying the display area according to the sequence of all the programs.

And sequencing the display areas corresponding to the programs according to the sequencing of all the programs, namely displaying the display area corresponding to the program which is broadcast firstly on the left side of the display area corresponding to the program which is broadcast later. Based on the length of the display area calculated above, the playing time period of the arranged display area corresponding to the program can directly and accurately correspond to the time in the time period to be displayed.

And arranging the program display areas of the programs broadcasted by each channel according to the steps and displaying the program display areas below the display time period.

And displaying the program name of the corresponding program in the program display area, so that the user can acquire the program name of the corresponding program by browsing each program display area. As shown in fig. 16, the program display area includes a character area (shown by a dashed line frame) for displaying the program name, and the distance between the character area and the borders on both sides of the display area is an inner distance, so that, as shown in fig. 17, when the program name is displayed in the program display area, two inner distances (shown by diagonal lines in fig. 17 for convenience of illustration, and no pattern is present in the actual electronic program list) exist between the program names of adjacent program display areas to separate the two program names, which is convenient for the user to distinguish, and improves the display smoothness of the display window.

Referring to the flow shown in fig. 18, the program name of the corresponding program is displayed in the program display area, and the specific steps are as follows:

s1801, acquiring the length of the program display area and the character length of the program name of the corresponding program.

In this embodiment, the inner distances in the program display areas may be the same, so that the length of the character area in the program display area can be obtained only by acquiring the length of the program display area, and for convenience of distinguishing, the initial length of the character area is referred to as a first length.

The display device 200 obtains the length S of the program display area and the length m of the inner edge distance, where the length of the inner edge distance may be a default value of the display device 200, for example, m is 14px, and may also be adjusted by the user. Thus, the first length L1 conforms to the following equation:

L1＝S-2m

the display device 200 obtains a character length a of a program name of a program corresponding to the program display area, generally, characters displayed in the character area have set character parameters, such as font, inter-character distance, font size, and the like, and the display device 200 calculates the character length of the program name based on the character parameters.

S1802, whether the character length is smaller than or equal to the first length is judged.

And S1803, if the character length is less than or equal to the first length, displaying the complete program name in the character area.

If the character length L3 is less than or equal to the first length, the caption character area may display the full program name, and at this time, the full program name may be displayed directly in the character area. Taking the program name "morning news" as an example, if the character length of the program name is smaller than the first length of the corresponding character area, the complete program name is directly displayed in the character area as the display area shown in fig. 19.

And S1804, if the character length is larger than the first length, judging whether the first length is larger than or equal to a length threshold value.

If the character length is larger than the first length, the description character area can not directly display the complete program name, and at this time, the program name including the indicator is displayed in the program display area, so that the user is indicated by the indicator that the currently displayed character in the program display area is not the complete program name. In some embodiments, the indicator may be an ellipsis, a designated pattern, or any other representation that indicates that the program name is not complete.

In the present embodiment, the length threshold may be set to a length equal to the character length of the indicator.

S1805, if the first length is greater than or equal to the length threshold, displaying the program name including the indicator in the program display area.

In this embodiment, the program name including the indicator includes a target character and an indicator, where the target character refers to a character selected from a first character in the program name, and the number of the target character is the maximum number of complete characters displayed in an area except for the indicator in the corresponding program display area.

For example, assuming that the length of each character is 3, the first threshold is 6, the program name is "lunch news", 4 characters in total, the corresponding character length is 12, the first length of the character area corresponding to the program presentation area is 9, and the inner edge distance is 2. At the moment, the character area can only display 3 complete characters at most, can not directly display the complete program name, and can display the combination of the target character and the indicator. Taking the example that the indicator corresponds to a character length, the maximum number of complete characters that can be displayed in the region except the indicator in the character region is 2, that is, the number of target characters is 2. The target character is 2 characters starting from the first character in the program title, i.e. "midday". As shown in the program presentation area of fig. 20, the program name "midday …" including the indicator is displayed in the character area.

S1806, if the first length is smaller than the length threshold, expanding the area for displaying the characters in the program display area, and displaying the program name including the indicator in the expanded area.

In this embodiment, the length of the character area can be extended by narrowing the inner margin, thereby increasing the number of characters that can be displayed.

S1807, a second length of the expanded region is obtained.

In this embodiment, in order to distinguish the change before and after the expansion of the character area, the length of the character area after the expansion is referred to as a second length.

As shown in fig. 21, the second length L2 of the expanded character area is the sum of the first length L1 of the original character area and the distance n1 and n2 of reducing the inner side distance on both sides, where n1 is less than or equal to m and n2 is less than or equal to m, that is, the second length satisfies the following formula:

L2＝L1+n1+n2

in some embodiments, only the left inner margin may be reduced, i.e., n2 ═ 0. In some embodiments, only the right inner margin may be adjusted, i.e., n1 ═ 0. In some embodiments, the inner edge distances of both sides can be adjusted simultaneously. In some embodiments, if the inner distances of adjacent program display areas need to be reduced, the sum of the distances between the adjacent inner distances of the adjacent program display areas after adjustment is not 0, so as to avoid the characters in the adjacent program display areas from being displayed without space.

S1808, determine whether the character length is less than or equal to the second length.

And S1809, if the character length is less than or equal to the second length, displaying the complete program name in the expanded character area.

If the character length is smaller than the second length, the character area after the expansion can directly display the complete program name, and at the moment, the complete program name is directly displayed in the character area after the expansion.

For example, it is assumed that the length of each character is 3, the length threshold is 3, the program name is "late", 1 character is total, the corresponding character length is 6, the first length of the character area corresponding to the program presentation area is 2, and the inner side distances on both sides are 1. The character area cannot display 1 complete character at this time. The length of the character area is extended by narrowing the inner side distances of both sides, for example, by 0.5, respectively, and the second length of the extended character area is 3. At this time, the character length is equal to the second length, and the complete program title can be directly displayed, such as the display area shown in fig. 22, and the complete program title "late" is displayed in the expanded character area.

And S1810, if the character length is greater than the second length, judging whether the second length is greater than or equal to a length threshold value.

If the character length is larger than the second length, it indicates that the expanded character area still cannot directly display the complete program name, and it is necessary to further determine the type of the program name that can be displayed in the expanded character area.

S1811, if the second length is greater than or equal to the length threshold, displaying the program name including the indicator in the expanded area.

In this embodiment, the program name including the indicator includes a target character and an indicator, the target character is a character selected from a first character in the program name, and the number of the target character is the maximum number of complete characters displayed in an area except for the indicator in the program display area.

For example, assume that each character has a length of 3, a length threshold of 3, and a program name of "night story", for 5 characters, the corresponding character has a length of 15, the first length of the character area corresponding to the program presentation area is 2, and the inner side distances on both sides are 3. It cannot be directly shown that the length of the character area is extended by reducing the inner side distances of both sides, for example, reducing the inner side distances of both sides by 2, respectively, and the second length of the character area after the extension is 6. However, the character length is larger than the second length, the complete program name cannot be directly displayed, and a combination of the target character and the indicator may be displayed, taking the example that the indicator corresponds to one character length, so that the maximum number of complete characters that can be displayed in the area of the expanded character area except for the indicator is 1, that is, the number of target characters is 1. The target character is 1 character from the first character in the program title, i.e. "night". As shown in the presentation area of fig. 23, the program name "night …" including the indicator is displayed in the expanded character area.

For example, it is assumed that the length of each character is 3, the length threshold is 3, the program name is "dinner", there are 2 characters, the corresponding character length is 6, the first length of the character area corresponding to the presentation area is 2, and the inner side distances on both sides are 1. At this time, the character area cannot display 1 complete character, and the length of the character area is extended by reducing the inner side distances of both sides, for example, by 0.5, respectively, and the second length of the extended character area is 3. Taking the example that the indicator corresponds to a character length, at this time, only one indicator is displayed in the expanded character area to indicate that the program display area has a corresponding program. As shown in the presentation area of fig. 24, only the indicator "…" is displayed in the expanded character area.

S1812, if the second length is smaller than the length threshold, not displaying the character in the program display area.

If the second length is less than the length threshold, the length of the expanded character area is such that a complete indicator is not displayed, and thus no character is displayed in the expanded area.

According to the steps of S1801 to S1812, the program name of the corresponding program is displayed in each program display area. If the channel has no program broadcast in the display time period, the channel displays a program display area corresponding to the display time period, and the program name in the display area is 'no program'.

Based on steps S601 to S604, an electronic program list is displayed, for example, the electronic program list shown in fig. 25 is displayed, the Channel list includes Channel names of Channel 1, Channel 2, and Channel 3, and the program names of the programs played by Channel 1, Channel 2, and Channel 3 in the display window in the display time period 15:00:00 to 17:00: 00. Based on the electronic program list, a user can quickly know the programs played by Channel 1, Channel 2 and Channel 3 in the display time period of 15:00: 00-17: 00:00 and the playing time periods of the programs, namely the playing time corresponding to the vertical mapping of the program display area of the programs on the display time period. The user can quickly know the program name of each program by browsing each program display area. If the program display area has no indicator, the characters displayed in the program display area are the complete program name, such as "dinner time", "drama"; if an indicator is present in the show area, indicating that the characters displayed in the show are not the complete program name, further action is required to view the complete program name, such as "…", "movie …", "new …"; if there is No program being played, then "No program" is displayed, such as "No program".

In some embodiments, if the user needs to further view the complete program name, the focus may be moved to the program display area corresponding to the program to be viewed by manipulating the control device. The display apparatus 200 determines a target program presentation area in which a full program title is to be presented by identifying the position of the focus to display the full program title. For example, the complete program name is displayed in a manner of scrolling and displaying characters in the program name in the program display area, so as to pop up an indication frame on the program display area, and display the complete program name in the indication frame, and so on.

In some embodiments, if the user needs to further view more detailed program information, such as a specific broadcast time period, a program duration, a complete program name, a summary of program content, and the like of a program, the control device may be manipulated to move the focus to a program display area corresponding to the program for which detailed program information is to be viewed, and a selection instruction is sent to the display device 200 to instruct the display device 200 to display the program information. The display device 200 displays the corresponding program information in the program detail window in the electronic program guide as shown in fig. 25 in response to the selection instruction. Illustratively, selecting the presentation area corresponding to "movie …" displays detailed program information in a program detail window, such as "New xx 2022 year, 4 month, 13 day, 16:10: 00-16: 35: 00"

In some embodiments, as shown in fig. 25, the sub-program list further includes a window for displaying the program content currently being played on the current channel, so that the user can continue to focus on the currently viewed program while browsing the electronic program list.

After receiving an instruction which is input by a user and indicates that an electronic program list is displayed, responding to the instruction by the display equipment, determining a first channel set based on a channel corresponding to a program picture, a channel in a pre-stored channel list and a preset channel display number, and determining a display time period based on the current time and a preset time period range; and determining programs of the first channel set in the presentation time period. The method comprises the steps of displaying an electronic program list, wherein the electronic program list comprises a first channel set and a display window, and the display window comprises a plurality of program display areas and is used for displaying program names of programs of the first channel set in a display time period. The length of the program display area is matched with the program duration of the program, wherein when the character length of the program name is greater than the length of the corresponding program display area, the program name displayed in the program display area contains an indicator, so that the user is prompted through the indicator that the currently displayed character is not the complete program name, and the complete program name needs to be further operated and displayed.
