Some embodiments of the disclosure provide a method for displaying an electronic program guide, applied to a display apparatus 200. The display apparatus 200 includes a display configured to display an image from broadcast system or Internet, and/or, a user interface; a communicator, configured to communicate with the network; a remote control, including a plurality of buttons; a memory, configured to store instructions and data associated with the display; and at least one processor, in connection with the display, the communicator and the memory.
As shown in
S601, in response to a command for displaying an EPG from a user, the display apparatus 200 obtains a set of target channels, a target time period and at least one program corresponding to the set of target channels within the target time period. The set of target channels includes all channels for presentation on a target presentation page. The target time period refers to a time period of presentation on the target presentation page.
When watching a program on the display apparatus 200, the user may input a command for displaying the EPG on the display apparatus 200 via a control device 100 or a smart terminal 300 so as to control the display apparatus 200 to display the EPG. The display apparatus 200, when displaying a program image, receives the command and obtains data for forming the EPG in response to the command.
Taking the control device 100 being a remote control as an example, and the user inputs a command via pressing an EPG button (a Guide button on some remote controls) on the remote control. The display apparatus 200 receives the corresponding command, recognizes a key value of “EPG” or “Guide” in the command and determines that the command is used for displaying the EPG based on the recognized key value. The display apparatus 200 obtains the data for forming the EPG in response to the command so as to generate the EPG based on these data.
In embodiments of the disclosure, the data for forming the EPG include; a channel set (also denoted as a first channel set) of channels for presentation in the electronic program guide, a time period (namely, a display time period) for program information presentation and information of the programs.
The electronic program guide shows channels and the corresponding program information in N presentation pages, and N is a positive integer greater than 0. Each presentation page shows a preset number of channels and information of the programs corresponding to the preset number of channels within a specified time period. For example, program information of programs corresponding to 10 channels within 10:00-12:00 today is shown in the display page. The number of channels for presentation in the display page and the specified time period may be pre-configured by a designer or may also be set by the user. There is merely one presentation page in the electronic program guide that is shown when the electronic program guide is displayed every time. A target presentation page is a presentation page shown in the electronic program guide on the display apparatus 200 in response to the command. The set of target channels includes channels shown in the target presentation page, the target time period is a time period for presentation in the target presentation page, and at least one program corresponding to the set of target channels within the target time period is one or more programs corresponding to the programs displayed in the target presentation page.
As shown in
S701, the display apparatus 200 determines a set of target channels based on a channel corresponding to a program image, one or more channels in a pre-stored channel list and a preset number of channels for presentation on EPG, and determines a target time period based on current time and a preset time period.
The channel corresponding to the program image refers to a channel currently played on the display of the display apparatus 200. The one or more channels in the pre-stored channel list refers to pre-obtained and stored one or more channels in the display apparatus 200, which can be played by the display apparatus 200, and the channel may have corresponding program data or not. A target channel lists may be determined in the following manners.
In some embodiments, the channel corresponding to the program image is a first channel in the target channel list. Channels in the target channel list includes m channels starting with the channel corresponding to the program image among the channels in the pre-stored channel list, and m is equal to the preset number of channels for presentation. For example, the channels in the pre-stored channel list are channel 1 to channel 100 in sequence, that is, the pre-stored channel list includes 100 channels, it is assumed that the preset number of channels for presentation is 10, if the channel corresponding to the program image is channel 20, the channels in the target channel list may be channel 20 to channel 29.
In some embodiments, the channel corresponding to the program image is an ith channel in the target channel list. The pre-stored channel list includes P paged channel lists, P is a positive integer greater than 0, each paged channel list includes channels of the preset number of channels for presentation, channels in the different paged channel lists are different, and the P paged channel lists constitute the complete pre-stored channel list. Each presentation page of the EPG shows merely one paged channel list, a paged channel list shown in the target presentation page is the target channel list, and the paged channel list includes the channel corresponding to the program image. The target channel list meets the following formula (1):
Here, Pj represents the target channel list, and the target channel list is a jth paged channel list in the P paged channel lists; floor function gives a round-off number when a ratio has a remainder; Cn represents that the channel corresponding to the program image is an nth channel in the pre-stored channel list; m represents the preset number of channels for presentation; Cx represents that the first channel in the target channel list is an xth channel in the pre-stored channel list; and Cy represents that the first channel in the target channel list is a yth channel in the pre-stored channel list.
For example, the channels in the pre-stored channel list are channel 1 to channel 100 in sequence, that is, the pre-stored channel list includes 100 channels, the preset number of channels for presentation is 10, if the channel corresponding to the program image is the 12th channel in the target channel list, the target channel list is the second paged channel list, the first channel in the target channel list is the 11th channel in the pre-stored channel list, and the last channel in the target channel list is the 20th channel in the pre-stored channel list. Accordingly, the channels in the target channel list are channel 11 to channel 20. Likewise, the first paged channel list are channel 1 to channel 10. The third paged channel list are channel 21 to channel 30.
In some embodiments, if the number of actual channels (channels belonging to the pre-stored channel list) in the target channel list is smaller than the preset number of channels for presentation, these actual channels are shown in sequence starting from a channel position corresponding to the first channel, and other channel positions in the target channel list are shown with null. Taking the channel corresponding to the program image being the first channel in the target channel list as an example, the channels in the pre-stored channel list are channel 1 to channel 100 in sequence, that is, the pre-stored channel list includes 100 channels, the preset number of channels for presentation is 10, if the channel corresponding to the program image is channel 99, the target channel list includes two actual channels which are channel 99 and channel 100, and the target channel list is shown by presenting channel names of channel 99 to channel 100 in the first to second channel positions in sequence and presenting null in the third to the tenth channel positions.
In embodiments of the disclosure, the current time refers to current system time (the system time is calibrated) of the display apparatus 200, and the display apparatus 200 obtains the current time by obtaining the current system time. The preset time period refers to a time range for presentation in the presentation page. The target time period refers to a preset time period including the current time. The target time period may be determined as follows.
In some embodiments, the current time is a start time of the target time period, and the preset time period refers to a duration. An end time of the target time period is time corresponding to a sum of the current time and the preset time period. For example, the current time is 10:00, and the preset time period is 2 hours, so the target time period is 10:00-12:00.
In some embodiments, the current time is a time point within the target time period, and the preset time period includes a specified start time and a specified end time. There are at least one preset time period, where the preset time periods are continuous and do not overlap with a period of time, and the preset time periods may constitute 24 hours of one day. The target time period is a preset time period including the current time, thus, the start time of the target time period is the start time of the preset time period(s), and the end time of the target time period is end time of the preset time period(s). For example, the current time is 10:00, if the preset time period includes 9:00-11:00 and 11:00-13:00, the target time period is 9:00-11:00.
In some embodiments, if the preset time period is the duration, for conveniently calculating the target time period for the display apparatus 200, the hour of the current time or the hour and the minute of the current time is used as the start time of the target time period.
In some embodiments, if the preset time period includes the specified start time and the specified end time, for conveniently determining the target time period for the display apparatus 200, the specified start time and the specified end time are set to show the hour, or show the hour and minute.
S702, the display apparatus 200 determines one or more programs corresponding to the set of target channels within the target time period based on the set of target channels and the target time period.
Program data of each channel corresponding to the target time period in the set of target channels are obtained. The channels in the set of target channels include various types, for example, a DTV channel, an Audio channel, an IP channel, a VIDAA++channel and the like.
These different types of channels have different implementations for obtaining programs and also have different program data formats. An EPG application parses programs of different data sources respectively, and processes them respectively to convert into a uniform data format for function and interface display of the EPG application.
The DTV channel and the Audio channel come from a digital video broadcasting (DVB) system. The DVB standards provide a complete set of digital television system specifications suitable for different media, which is established based on an MPEG-2 standard compression algorithms.
Different types of the DVB standards can be used, for example, DVB-T, DVB-C, and DVB-S.
The modulation and demodulation modes of these DVB standards are different, but they are the same in source encoding and transformat, which are uniformly packed according to an MPEG-2 standard to form a transport stream (TS).
MPEG-2 standard is short for “information technology—generic coding of moving pictures and associated audio information”. A basic bit rate is 4-8 Mbps and reaches as highest as 15 Mbps. The standard includes contents such as video and audio content. In the standard, program specific information (PSI) is defined specifically, which is used for accurately locating a program from a certain TS carrying a plurality of programs.
A PSI table defined in the MPEG-2 standard is a description for a single TS. As a plurality of TSs usually exist in a system, in order to guide a digital television user to quickly locate the needed service in the TSs, DVB expands the PSI of MPEG-2, and a table is added on the basis of four tables of PSI to form ServiceInformation (SI). The SI describes all the TSs of the whole system. The SI defined by the DVB standards is inserted into the transport stream (TS) meeting the MPEG-2 standard, so that a television may extract a list of programs and program information from the TS and display them for the digital television user visually, and thus the user may watch and select a television program more conveniently.
Tables in the PSI are as follows:
Tables in SI are as follows:
Through the PSI and SI, searching and location all transmitted information such as program names and program classification as well as program contents and specific playing time the next many days are more conveniently and more quickly. The EPG function of the television provides program data to the user in a graphical mode and provides functions such as program marking and filtering, so that the user may mark different types of programs in the EPG according to the user's own preferences.
A program of an IPTV channel is obtained from a third-party service provider according to an HTTP protocol through a network. The program Array<IpProgram> in JSON format are obtained from service provider and uniformly parsed by an EPG module to be in an Array<Program> format for associated functions and program display.
A program of a VIDAA channel is a content provided by VIDAA service provider and is obtained, similar to the IPTV, from a service provider according to an HTTP protocol through network. The program Array<VidaaProgram> in JSON format are uniformly parsed by the EPG application to convert to an Array<Program> format for associated functions and program display.
Referring to
For example, types of program according to DVB related standard may include Movie, News, Shows, Sport, Children's, Music, Arts, Social, Education, Hobby, Series, Drama and Others. Here, the types may be different in different countries and regions.
Based on the program list defined in the MPEG-2 standard, theme information and component information (componentInfo) can be determined.
The theme information is denoted as a value. The EPG application can create a mapping list for the types of program based on the DVB standard, such as: 1=Movie, 2=News, 3=Shows, 4=Sport and so on. When parsing the theme data, the mapping list of program types can be referenced and the corresponding type of program can be determined. For example, if the value of theme data is 1, type of program can be determined as Movie based on the mapping 1=Movie; if the value of theme data is 4, type of program can be determined as Sports based on the mapping 4=Sports.
The componentInfo is a set of data including video, audio, and subtitle.
The EPG application can create a mapping list for componentInfo based on the DVB standard, which is two-dimensional data and the data format may be defined as follows:
The componentInfo data of program is a set of data including video, audio, and subtitle. Each item in the set of data includes two pieces of ID data which are streamID and componentID. The streamID corresponds to the one-dimensional data in the mapping list of componentInfo and the componentID corresponds to the two-dimensional data in the mapping list of componentInfo.
The set of componentInfo data of program may include, for example:
When parsing the set of componentInfo data of program, {streamId: 1, componentId: 3} can be obtained based on the first item of the set of componentInfo data of program, streamId is determined as a first dimensional data, and componentId is determined as a second dimensional data, and the data 1-3 can be obtained via combination of the first dimensional data and the second dimensional data, then 1-3=video 16:9 HD can be determined based on the mapping list of the componentInfo, which indicates that there is video of high definition displayed in 16:9 in the program.
{streamId: 2, componentId: 3} can be obtained based on the second item of the set of componentInfo data of program, and the data 2-3 can be obtained via combination of the first dimensional data and the second dimensional data, then 2-3=audio HD can be determined based on the mapping list of the componentInfo, which indicates that there is audio in the program, and the program is of audio description (AD) type.
{streamId: 3, componentId: 3} can be obtained based on the third item of the set of componentInfo data of program, and the data 3-3 can be obtained via combination of the first dimensional data and the second dimensional data, then 3-3=subtitle sign language can be determined based on the mapping list of the componentInfo, which indicates that there is subtitle in the program, and the program is of sign language (SL) type.
If there is no video content in the program, there is no item of streamID=1 in the corresponding set of componentInfo data. Here, streamID=1 indicates that there is the video content.
Likewise, if there is no audio content in the program, there is no item of streamID=2 in the corresponding set of componentInfo data. Here, streamID=2 indicates that there is the audio content.
If there is video, audio and subtitle content in the program, the componentInfo of the program is null, in this case, no data can be determined by parsing and matching with the mapping list.
Based on the theme data and componentInfo data of the program, information of the type of the program, whether there is sign language, and whether there is audio description can be determined. The determined information can be stored in the attribute information of the program. For example, the attribute information of the program can be described as follows:
Based on the above, when setting of the type of program is changed, it is determined whether program corresponds to this type and then the interface may be changed accordingly. When setting of filter rule of the program is changed, it is determined whether the program supports the functions corresponding to the subtitle, AD, and SL, and then the interface may be changed accordingly.
While data of program of an IPTV channel obtained from a third-party service provider is maintained by the third party, and includes theme, subtitle, AD, SL data for use by the EPG application.
Data of program of a VIDAA channel obtained from VIDAA service provider is maintained by the VIDAA service provider, and includes theme, subtitle, AD, SL data for use by the EPG application.
The display apparatus 200 obtains program data corresponding to the target time period from a data source corresponding to a channel. For example, if it is the DTV channel, the program data are obtained from a digital television signal source.
The program data include a program name, start time, end time, program content and the like. The display apparatus 200 may determine the corresponding program of each channel in the set of target channels within the target time period based on the program data. For example, if the program data of Channel 11 within 10:00-12:00 obtained by the display apparatus 200 are “competition A, 10:00-11:30; advertisement B, 11:30-11:35; and news C, 11:35-12:00”, programs of Channel 11 within 10:00-12:00 are competition A, advertisement B and news C in sequence according to a time sequence.
S602, the display apparatus 200 displays the electronic program guide including a target presentation page on the program image, where the target presentation page includes a plurality of areas for channel presentation and a plurality of areas for program presentation. The area for channel presentation is used for presenting a channel name. The area for program presentation is used for presenting a name of a program, and a length of each area for program presentation matches (such as being proportional to) a duration of the program. Each area for program presentation is labeled with a tag, the tag may be visual and the tag corresponds to a program type of the program in the area for program presentation.
The display apparatus 200 generates the electronic program guide, and the electronic program guide includes the target presentation page. The target presentation page is used for presenting corresponding channel data of the target channel list and program information of one or more corresponding programs in the target channel list within the target time period.
The target presentation page includes the plurality of areas for channel presentation, and the area for channel presentation is used for presenting the channel name. The number of the areas for channel presentation is equal to the number of channels in the target channel list, each area for channel presentation is used for presenting a name of one channel in the target channel list, and different areas for channel presentation are used for names of the different channels. All the areas for channel presentation are arranged longitudinally, each row includes an area for channel presentation. The name of each channel is shown in an area for channel presentation in sequence according to an arrangement sequence of all the channels in the target channel list.
The target presentation page includes a plurality of areas for program presentation, and the area for program presentation is used for presenting the program name. The number of the areas for program presentation is equal to the total number of the corresponding programs in each channel in the target channel list within the target time period, each area for program presentation is used for showing a name of this program, and the different areas for program presentation are used for showing names of the different programs. Areas for program presentation with names of programs belonging to the same channel are located in the same row, and areas for program presentation with names of programs belonging to different channels are located in different rows. The names of programs are shown in the areas for program presentation located in the same row in sequence from left to right according to a playing time of the programs.
The area for channel presentation and the areas for program presentation are shown in parallel, and the area for channel presentation and the area for program presentation which correspond to the same channel are located in the same row. Heights of the area for channel presentation and the area for program presentation located in the same row are the same. A width of each area for program presentation located in the same row matches a program duration of a corresponding program, that is, the longer the program duration is, the larger the width of the corresponding area for program presentation is. In some embodiments, a width of each area for program presentation may be obtained by calculation based on a ratio of a duration to a presentation width. Thus, the user may know a length of the program duration of each program by browsing the width of each area for program presentation.
In some embodiments, the electronic program guide may also include a time axis, and a time period corresponding to the time axis is same with the target time period. The time axis is shown above the area for program presentation, and time in the time axis is aligned with playing time of the corresponding program.
In some embodiments, the electronic program guide further includes a displaying window. The displaying window is used for displaying a program image currently played.
In some embodiments, the electronic program guide further includes a window for program detail. The window for program detail shows information of a program where a focus lands, and the information includes a channel corresponding to the program, the program name, the playing time, the program duration, a brief of the program and the like.
In some embodiments, the electronic program guide further includes an indicator line. The indicator line is shown in the area for program presentation and used for indicating the current time.
Description is made by taking the electronic program guide 800 shown in
It may be known from the electronic program guide 800 that the larger the number of the channels for presentation in the electronic program guide 800 is and/or the longer the presentation time period is, the more the names of programs in the electronic program guide 800 are, and the denser the arrangement of the areas for program presentation is. If the user determines a program of interest by browsing the program names, the dense areas for program presentation are inconvenient to browse for the user, identification difficulty is increased for the user, and moreover, the user tends to mistakenly identify other programs as the program of interest.
In view of the above issues, a tag is added to each area for program presentation 8012, the added tag corresponds to the program type of the program in the area for program presentation, and the same program type corresponds to the same tag. In embodiments of the disclosure, the tag should be easy to identify and distinguish, for example, using a simple-shaped tag, using a distinct color, a larger difference between different tags and the like. Thus, the user, when browsing the electronic program guide, may quickly identify the tag on each area for program presentation and quickly and accurately distinguish different tags, so as to quickly and accurately determine the program type of the program corresponding to each tag, and thus determine whether it is the program of interest based on the program type of the program.
The display apparatus 200 may add the tag to each area for program presentation, as shown in
S901, the display apparatus 200 obtains a program type of a program and a preset correspondence between the program type and a tag.
The display apparatus 200 obtains program data of each channel in the set of target channels corresponding to the target time period when determining the corresponding programs in the set of target channels within the target time period. A process of obtaining the program data is similar to S702 and is not repeated in detail here.
In embodiments of the disclosure, the program data include program data of a first type. The program data of the first type includes basic data such as the program names, start time, end time and the program content. The program data further include program data of a second type, and the program data of the second type includes data related to the program content and data for indicating the program type.
In some embodiments, the program type may be classified according to the program content, and this program type may be referred to as a first program type. These program types are obtained from channels based on the DVB broadcast signal standards, such as the DTV channel, the Audio channel and the IP channel based on DTV. For example, the first program type corresponding to program data may be determined by recognizing Genre data in the program data. The Genre data include: Movie, News and Factual, Entertainment, Shows, Music, Sport, Children's, Education, Lifestyle, Drama, Unclassified, News, Social, Series, Others and the like. Taking Genre data being Movie as an example, the corresponding first program type is a movie type. Each program belongs to one type of the first program type, so all the programs in the electronic program guide may be classified according to the program contents according to the first program types.
In some embodiments, the program types may be classified according to function data carried in the program contents, and this program type is referred to as a second program type. These program types are also obtained from channels based on the DVB broadcast signal standards, such as the DTV channel, the Audio channel, and the IP channel based on DTV. For example, the second program type corresponding to program data may be determined by recognizing the function data in the program data. The function data include: Subtitle, Audio Description. Sign Language and the like. Each program may include N pieces of function data, N is a positive integer greater than 0, that is, each program may provide one or more functions. Taking the function data including Subtitle as an example, the corresponding program type is a type providing a subtitle. Taking the function data including Subtitle and Sign Language as an example, the corresponding second program type is a type for providing the subtitle and a type for providing the sign language.
In embodiments of the disclosure, the correspondence between the program type and the identifier may be pre-configured for the display apparatus 200, that is, a default correspondence, or may also be defined by the user. For conveniently distinguishing the program types corresponding to different classifying schemes (namely, the first program type and the second program type), the first program type and the second program type correspond to different tags, the first program type corresponds to a first type of tag, and the second program type corresponds to a second type of tag.
If the correspondence between the program type and the identifier (for example, the tag) is defined by the user, the user may set the corresponding relationship between the program type and the tag after the display apparatus 200 displays the electronic program guide. As shown in
S1001, the display apparatus 200 displays a setting interface in response to a command for displaying the setting interface from the user. The setting interface is used for setting the correspondence between the program type and the tag by the user.
The setting interface includes a first setting interface and a second setting interface, the first setting interface is used for the user to select the first type of tag to be used and select the first program type marked with the selected first type of tag and may be referred to as a program type setting interface. The second setting interface is used for the user to select the second program type to be highlighted, which is the program type preferred by the user, and accordingly the second setting interface may be referred to as a preference program setting interface.

In some embodiments, there is no tag in the electronic program guide currently displayed on the display apparatus 200. That is, there is no pre-stored corresponding relationship between the program type and the tag. The user sets the corresponding relationship between the program type and the tag to enable the respective programs to be displayed with tags for classifications. In some embodiments, the electronic program guide currently displayed on the display apparatus 200 has presented the tag corresponding to the program type on the area for program presentation. That is, there is the pre-stored corresponding relationship between the program type and the tag, for example, the corresponding relationship set by the user last time. The user updates the tag displayed on the area for program presentation by setting the corresponding relationship between the program type and the tag.
The following specific description is made for the user setting the correspondence between the program type and the tag based on the different setting interfaces.
The first program type is mainly based on classification of the program contents without filtering of the program contents, thus, the first type of tag may adopt schematic tags without affecting functions (such as a function for selection and a display function) of the area for program presentation, for example, an icon (including a style, color and the like of the icon), a color of the area for program presentation, a pattern of the area for program presentation, a font color of the program name and the like. Different first program types may have different tags of the first type.
In some embodiments, the first program type is determined according to genre data in program source signals, and the genre data includes one or more of: Movie, News, Entertainment, Shows, Music, Sport. Children's. Education, Lifestyle, Drama, Unclassified, Social, or Series.

Referring to
The display apparatus 200 controls the first display area 2602 to display the channel classification list, the channel classification list is used for displaying different types of the channels in a classified mode through different type controls 2604, such as a movie control, a favorite control and a kid control.
The display apparatus 200 controls the second display area 2603 to display the channel list and the program list, the channel list is used for presenting different channels via different channel controls 2605, and the program list includes program information in each channel in different playing time periods in form of the different program controls 2606. When the display apparatus stores the electronic program guide information, channel information therein may be stored with the corresponding channel identifiers simultaneously, that is, each channel is marked with the channel tag. The channels with the same channel tag belong to the same type in the channel classification list, for example, the channels playing a movie type of program are labeled with DY, and after the user selects a type control for representing movie in the channel classification list, the display apparatus 200 obtains the channels with the DY tag and displays the channels in the second display area 2603. Correspondingly, the display apparatus 200 obtains program information in the channels with the DY tag and synchronously displays the program information in the second display area 2603, as shown in
In some embodiments, the longer a playing duration of the second multimedia resource corresponding to program information is, the larger a length of the corresponding program control is. As shown in
In some embodiments, when the user controls the focus to move to a first type control in the channel classification list, the display apparatus 200 obtains channels labeled with the channel tag corresponding to the first type control and generates a channel list, and displays the channel list in the second display area 2603. The display apparatus 200, when storing the electronic program guide information, can pre-generate a mapping relationship between each channel and program information in the channel according to each channel and the program information corresponding to each channel, and after the channel list is displayed in the second display area 2603, the display apparatus 200 obtains the corresponding program information to display, specifically, the channel controls and the corresponding program controls are controlled to be displayed in row. As shown in
In some embodiments, when the focus lands in the channel list, the user may select a channel in the channel list that the user intends to watch by pressing an up/down button on the remote control. The display apparatus 200 displays a channel control with the focus and the corresponding program information in a first row in the second display area in response to a command from the user, and a height of the first row in the second display area is greater than heights of the rest of rows in the second display area. As shown in
For example, as shown in
In some embodiments, in the program list, a fixed-focus position is set as the first one in a first row via a fixed-focus mode. As shown in
S2503: in response to a command for controlling the focus on the floating layer to move, selecting program information in the electronic program guide.
S2504: determining whether the program information can be played.
In some embodiments, when the user selects a piece of program information by a direction button on the remote control, the display apparatus 200, when receiving a selection of the corresponding program control from the user, needs to check whether the program is within playing time, if yes, it is determined that the program can be played, and if not, it is determined that the program cannot be played. In general, the program that can be played is usually a live broadcast program, or a program already played, and the program that cannot be played is usually a program which is not scheduled to start.
S2505: obtaining a second multimedia resource corresponding to the program information, and stopping playing the first multimedia resource and playing the second multimedia resource on the playing interface.
In some embodiments, when the program corresponding to selected program information can be played, the display apparatus 200 sends to the server 400 a media resource request for the program, so as to make the server 400 feed back the second multimedia resource of the program. The display apparatus 200, upon receiving the second multimedia resource, controls to stop playing the first multimedia resource and play the second multimedia resource, and the playing interface of the first multimedia resource switches to the playing interface of the second multimedia resource.
S2506: generating prompt information for indicating that a current program cannot be played, and continuing to play the first multimedia resource on the playing interface.
In some embodiments, when the program corresponding to the selected program information cannot be played, the display apparatus 200 generates the prompt information for indicating that the current program cannot be played, for example, the current program control is set to jitter based on a CSS property, or displays a prompt box of “a current program cannot be played”, or the like, so as to prompt the user that the current selected content cannot be played. Meanwhile, the first multimedia resource continues to be played.
In the disclosure, a fixed-focus mode is adopted at the program list, that is, the focus position keeps the same size all the time, and in the related art, a position of each control in the list needs to be calculated every time the focus moves.
In some embodiments, the program list is stored as an array in the memory, during rendering, data traversing is performed on the array by using for cycle, each piece of traversed data fills in a corresponding html component, and the list is completed.
A program (the program 3) currently being played and a program next to or following program 3 are determined according to the current time and time information in the program data. The current program (the program 3) is set to have a required fixed width based on a width property. A control of the program 3 is set to be in the leftmost of a visible area based on a css left property. A position of the subsequent program is a width of a previous program plus a gap between the programs. Thus, pieces of program information are rendered to be a transverse list.
Elements outside the program list visible area are concealed, that is, the program controls 1, 2 and 6 are concealed. A size of the focus position (program 3) is fixed all the time, so a position of each program control in the list relative to the program control 1 may update every time the focus moves. A size and a position of the program control need to be adjusted every time the focus moves right and left.
For example, the size of the focus position is fixed as 20 rem, and the program 3 is a focus program currently.
When the focus moves right, the control of program 3 is restored from the fixed size (20 rem) to an actual size (calculated according to a program duration, such as 23 rem), the whole list is moved leftwards, and a moving distance is the actual size (23 rem) of the program 3.
In this case, the program 4 will be located on a leftmost side of the visible area, and the control of the program 4 is adjusted from the actual size (such as 14 rem) to the fixed size (20 rem). A distance between the program after the program 4 from a left side is adjusted in sequence to complete movement of the list.
It may be seen that program data of many programs need to be adjusted in one-time movement. A position of each element in the whole list needs to be calculated again.
For example, when there are 30 programs in the list, a position relationship among the 30 programs needs to be calculated every time the focus moves.
In some embodiments, in the first row of the program list, the display apparatus 200: in response to a command for indicating a right move or a left move, updates data in the second sub-area 3102 to program information corresponding to a program control where the focus lands during movement, and controls a program control in the third sub-area 3103 to move in a direction opposite to the right move or the left move. In the channel list, the display apparatus 200: in response to the command for indicating an upwards move or a downwards move, updates data in the first sub-area 3101 to a channel corresponding to a channel control where the focus lands during movement, updates data in the second sub-area 3102 to program information indicated by a first program control corresponding to the channel control in the first sub-area 3101, updates data in the third sub-area 3103 to program information indicated by a program control except for the first program control in the first sub-area 3101, and updates the channel controls in the area for several rows 3104 and the corresponding program controls.
In other words, the control with the fixed size and position is set as an independent area, based on different properties of all the controls in the electronic program guide.
In embodiments of the disclosure, different areas are distinguished through an interactive design of the EPG interface.
The controls are interface objects drawn by using html elements.
A data format is saved as a JS object in the memory, and the content is information needed for program display and program search. For example:
For example, the first sub-area 3101, the second sub-area 3102 and the third sub-area 3103, merely two fixed-size controls need to fill in the first sub-area 3101 and the second sub-area 3102, and when the focus moves right and left, it merely needs to monitor the corresponding data independently for drawing.
The EPG application uses the VUE framework, and a core function of the framework is two-way binding of data. When data for rendering change, it may be automatically reflected onto the interface.
A core principle of data monitor is Object.defineProperty (a Proxy property) provided by JavaScript (js) native version. The js property allows hijacking of js data. When the data change, a using party hijacks the data change for performing a corresponding action.
That is, data to be displayed in the first sub-area 3101 and the second sub-area 3102 merely needed to be processed (the second sub-area 3102 is updated to data in a program control of the third sub-area 3103).
The second sub-area (namely, the focus position) here includes one time change of element data, but the position does not change all the time, which does not involve position recalculation and is low in rendering cost.
Correspondingly, in the third sub-area 3103, a focus obtaining process is not involved, so adjustment of a size of the program control is not needed, a distance from the leftmost side does not change, thus, during right-left movement, merely regular translation or lateral move is performed (a position of the program control in the third sub-area 3103 is translated leftwards/rightwards by one element).
The above regular translation is a scheme used during movement of the third sub-area and is a part of an interface operation scheme of the disclosure. As for regular item translation for a list, after rendering of the list is completed, the list is used as a whole, and there is no relative position change among the elements in the list. When the list moves, the list needs to be moved in whole merely based on a ess native transform property instead of changing each program element, and good performance is achieved. Lateral move is performed by using translateX, and vertical move is performed by using translate Y.
The regular translation or lateral move is only to change an element position. Merely one control needs to be recalculated, and calculation cost is reduced.
Likewise, as for the area for several rows 3104, the area for several rows 3104 is separated from the first row in the second display area and is a relative independent area. When the focus moves up and down, the display apparatus obtains a previous row/a next row in the channel list, the first sub-area 3101 is updated with a new channel, the second sub-area 3102 is updated with the first one ranked first in program(s) from the new channel, and the third sub-area 3103 is updated with other data in the program(s) from the new channel except for the first one. Meanwhile, data of channels and programs below the new channel are calculated and updated, and filled into the area for several rows 3104.
Through the display apparatus in the disclosure, the electronic program guide may be displayed on the playing interface presented in a full screen mode via the floating layer with transparency, so that the user can display the electronic program guide while playing the media resource in a full screen mode, and user experience is improved. Specifically, by dividing into a plurality of sub-areas, while interface rendering is implemented, there is no increased number of html elements to be drawn, that is, the number of controls is not increased. Meanwhile, the number of controls to be recalculated is reduced. When the focus moves, processing of dozens of controls is reduced to processing of merely two controls which includes one time element change (the second sub-area) and regular translation (the third sub-area). Accordingly, in a process of implementing data loading and rendering, the number of the controls is not increased, the number of controls for recalculation during focus move is reduced greatly, and processing performance is improved.
In some embodiments of the disclosure, a method for displaying an electronic program guide is further provided. The method includes: in response to a selection of a media resource control in a media resource list page, causing the display to display a playing interface in a full screen mode, the playing interface is used for displaying a first multimedia resource corresponding to the media resource control; in response to a command for launching the electronic program guide, causing the display to display a floating layer with transparency above the playing interface and controlling the floating layer to load and display the electronic program guide; in response to a command for move a focus to a program item on the floating layer, selecting program information associated with the program item in the electronic program guide. The display apparatus obtains a second multimedia resource corresponding to the program information in response to the selected program information being within a current playing time, and switches the playing interface of the first multimedia resource to the playing interface of the second multimedia resource. The display apparatus generates prompt information for indicating that a current program cannot be played in response to the selected program information being not within the current playing time, and controls the playing interface to continue playing the first multimedia resource.
In some embodiments, the floating layer includes a first display area and a second display area. The method further includes: the display apparatus controls the first display area to display a channel classification list, the channel classification list includes different types of channels in a classified mode in form of different type controls. The display apparatus 200 controls the second display area to display a channel list and a program list, the channel list is used for displaying different channels in form of different channel controls, each channel is labeled with a channel tag, and channels with the same channel tag belong to the same type in the channel classification list; the program list is used for displaying program information in each channel in different playing time periods in form of different program controls; and the longer a playing duration of the second multimedia resource is, the larger a length of the corresponding program control is.
