Among them, music chapters are audio-type chapters, and generally have no substantial video content. Video chapters contain video images, which may be subdivided into advertisement chapters (including but not limited to head/mid/tail advertisements), feature chapters, and the like, by video attributes. It should be noted that the chapter types are not limited to examples of embodiments of the present application, and specifically, the chapter types are based on classification standards set by different operators.

Fig. 5 is a schematic diagram of a program playing interface according to some embodiments of the present application. Referring to fig. 5, a program playing interface is used to display video content of a current program, a recording button 51 may be provided on the program playing interface, and the controller 250 controls the display to display a recording task creation page in response to an operation of clicking the recording button 51 by a user.

Fig. 6 is a schematic diagram of a recording task creation page according to some embodiments of the present application. Referring to fig. 6, the recording task creation page may include several recording options, a submit button 65, and a close button 66. Among the recording options include, but are not limited to: recording mode option 61, recording duration option 62, file save option 63, chapter recording option 64, etc.

In some embodiments, referring to fig. 6, a recording mode option 61 is used to select an immediate recording mode or a scheduled recording mode. If the user selects the scheduled recording mode, the recording options further include a scheduled start time option 61a, where the scheduled start time option 61a is used to set the start execution time of the recording task, and the time unit refers to the time of year, month, day, and time division, and may be further refined to seconds. If the user selects the immediate recording mode, the reservation recording start time option 61a is not displayed, and recording is started immediately by default when the recording task creation is completed.

In some embodiments, referring to fig. 6, the user sets the reserved recording duration through the recording duration option 62, where the recording duration option 62 may provide a number of fixed duration options and custom options, and the duration options may be, for example, 15 minutes, 30 minutes, 1 hour, 2 hours, etc., and the user may also input the reserved recording duration according to his will, for example, input 45 minutes, through the custom options, so as to limit the recording duration of the program.

In some embodiments, referring to fig. 6, the file save option 63 may include a disk option 63a and a save mode option 63b, after the user triggers the disk option 63a, the controller may generate and control the display to display a disk list according to the connection state of the disk interface, where the disk list includes relevant information of the currently available disk, such as, but not limited to, a disk name, a remaining available memory/memory capacity of the disk, and so on, for example, for "U disk, 30G/64G", which indicates that the memory capacity of the U disk is 64G, 34G has been used, and the remaining available memory is 30G. And the user selects a target disk from the disk list as a storage path to store the recorded file. The save mode option 63b is used to turn on or off an automatic save function that automatically saves the recorded file to the target disk when the recording end condition is satisfied.

In some embodiments, the display device may be configured with the functionality to categorize recorded programs by chapter, enabling the user to select which type or types of chapter content are desired to be recorded as desired. After the user triggers the chapter recording option 64, the controller controls the display to display a chapter type list, see fig. 6, which includes a first selection button 64a corresponding to at least one chapter type, including but not limited to an advertisement chapter, a feature chapter, a music chapter, etc., and the user can set the first selection button 64a corresponding to at least one chapter type in the chapter type list to a selected state to thereby select one or more chapter types desired to be recorded. If the user does not select any chapter type, the controller defaults to record the complete program video.

In some embodiments, after the user completes the parameter setting of the above recording options, the user may click on the submit button 65, and the controller creates a corresponding program recording task according to the setting parameters of each recording option. If the immediate recording mode is implemented, the controller records the current program according to the chapter type selected by the user when the program recording task is successfully created; if the reserved recording mode is implemented, the controller records the current program according to the chapter type selected by the user when the system time reaches the reserved recording starting time set by the user. If the user clicks the close button 66, the controller cancels the creation of the program recording task, closes the recording task creation page, and may control the display to return to the program playing interface illustrated in fig. 5.

In some embodiments, for example, program a includes chapter 1 (commercial), chapter 2 (feature), chapter 3 (music), chapter 4 (feature), and chapter 5 (commercial) distributed in the playback timing. If the type of the chapter selected by the user is the feature chapter, the controller records only chapter 2 and chapter 4 in the program a, and skips the recording of chapter 1, chapter 3 and chapter 5. Assuming that the type of chapter selected by the user is a music chapter, the controller records only chapter 3 in program a, skipping the recording of chapter 1, chapter 2, chapter 4, and chapter 5.

In some embodiments, the controller may create a folder in the target disc based on the channel information and the program information and store the recorded media file in the folder before recording the chapter code stream in the target disc. Wherein the channel information includes, but is not limited to, channel name, channel number, etc., and the program information includes, but is not limited to, program name, etc., for example, folder name "CCTV 1-news simulcast".

In some embodiments, taking the foregoing program a as an example, assuming that the chapter type selected by the user is a feature chapter, the controller may splice chapter 2 and chapter 4 in time sequence and record as one media file. Thus, the user can open the folder corresponding to the program A in the target disk, click and play the media file, and realize continuous viewing of the content of the chapter 2 and the chapter 4 in the same media file.

In some embodiments, taking the foregoing program a as an example, assuming that the chapter type selected by the user is a feature chapter, the controller may record chapter 2 and chapter 4 respectively, sequentially obtain a chapter file a-1 corresponding to the chapter 2 and a chapter file a-2 corresponding to the chapter 4, and store the chapter file a-1 and the chapter file a-2 as independent media files (not spliced) in the folder of the program a. Thus, after the user opens the folder corresponding to the program a in the target disc, the playback chapter 2 and/or chapter 4 can be selected.

Fig. 7 is a schematic diagram of a chapter catalog page that is displayed when playback of a recorded file is provided in some embodiments of the present application. When the user wants to play back the program a and opens the folder corresponding to the program a in the target disc, the controller may control the display to display a chapter catalog page, referring to fig. 7, the chapter catalog page may include channel information, program information (e.g., channel 1-program a) and a chapter playback control 71 corresponding to the recorded chapter, and the chapter playback control 71 may include information such as a chapter type, a chapter name, and the like.

In some embodiments, assuming that the user has selected to record feature chapters in program A, see FIG. 7, the channel program example is channel 1-program A, and the chapter catalog page also includes two chapter playback controls 71 corresponding to feature 1 (chapter 2) and feature 2 (chapter 4). When the user clicks any chapter playback control 71, for example, the user clicks the chapter playback control 71 of "feature 1", the controller may start the media player and control the media player to play the chapter file a-1 corresponding to the feature 1 (chapter 2), so as to realize the independent recording and playback of the program according to the chapters.

In a scenario where programs are recorded according to chapter categories, recording failure may occur because a user cannot pre-judge chapters included in the programs and types of the chapters in advance, so that the user cannot review recorded media files, for example: the program B comprises a chapter 1 (feature film), a chapter 2 (advertisement) and a chapter 3 (feature film) distributed according to a playing time sequence, and if the chapter type selected by a user is a music chapter, after receiving a code stream of the program B, the controller sequentially identifies that the chapter 1 to the chapter 3 of the program B do not belong to the music chapter, and then the recording program of the chapter 1 to the chapter 3 of the program B is not executed, so that the recording of the program B fails, a folder corresponding to the program B in a target disk is empty, and the user misses the program B, and cannot review the chapter content in the program B at any time.

Fig. 8 is a flowchart of a first program recording method according to some embodiments of the present application. In order to solve the related problems in the program recording scenes according to chapter classification, referring to fig. 8, an embodiment of the present application provides a program recording method for pre-judging recording failure risk before recording a program, the method includes the following steps:

step S81, in response to the operation of the user to create the recording task of the target program, the display is controlled to display the recording task creation page.

With reference to the foregoing description of the related embodiments, the user may select a chapter type (hereinafter referred to as a first chapter type) of a chapter to be recorded in the target program in the recording task creation page, and may set other parameters, where the other parameters include, but are not limited to: recording mode, reserved recording time, target disk and storage mode, etc.

Step S82, at least one first chapter type selected by the user based on the recording task creation page and a first program type corresponding to the query target program are obtained.

The user may select at least one first chapter type, for example, a music chapter, or an advertisement chapter and feature chapter.

In some embodiments, the display device may be configured with a program information module for acquiring and storing program information, where the program information module acquires the program information by way of, for example, a program code stream or EPG, where the program information includes, but is not limited to, a program name, a program type, a program duration, and the like. The controller may query the program information module for the program type of the target program (simply: the first program type), wherein the program type is related to the attribute and genre label of the program content, and the program type includes, but is not limited to: music type, sports type, shopping type, movie type, news type, etc.

Step S83, it is determined whether the first chapter type matches the first program type.

In some embodiments, the display device may preset a probability relation table including probability information between any program type and any chapter type. The probability information is used for describing failure probability when recording any type of chapter in any type of program, and the higher the failure probability is, the larger the recording failure risk is (intervention and reminding are possibly needed), and the lower the failure probability is, the higher the recording success probability is.

TABLE 1

Table 1 is an example of a probability relation table 1, and the probability information in table 1 describes the failure probability in text, for example, "normal", "failure probability is high", etc., where "normal" is used to describe that the failure probability is very low (recording is basically successful under normal conditions). The probability relation table may further include chapter selection suggestion information, where the chapter selection suggestion information is used to suggest switching to a chapter type with a high recording success probability when the failure probability is high, for example, the program C is a music type, and if the user selects to record a feature chapter in the program C, the failure probability is high, and the selection of a music chapter is suggested.

TABLE 2

Table 2 is an example two of a probability relation table, and the probability information in table 2 describes the failure probability in terms of values, such as "99%", "1%", etc., and the larger the value is, the higher the failure probability is represented, and the smaller the value is, the higher the probability that recording is successful is represented. In some embodiments, the controller may record and count the success/failure of the historic recording task, and based thereon, calculate a value of failure probability between any program type and any chapter type. It should be noted that the failure probability values in table 2 are merely exemplary, and the presentation form and the setting standard of the probability information are not limited.

In some embodiments, the controller may call a probability relation table when performing step S83, refer to table 1, determine that the first chapter type matches the first chapter type if probability information between the first chapter type and the first chapter type is described as "normal", and the controller performs step S84; if the probability information between the first program type and the first chapter type is described as "failure probability high", it is determined that the first chapter type does not match the first program type, and the controller performs step S85 and step S86.

In some embodiments, the controller may call a probability relation table in which failure probabilities between the first program type and the first chapter type (simply referred to as first failure probabilities) are queried with reference to table 2 when performing step S83. If the first failure probability is less than the first threshold, determining that the first chapter type matches the first program type, the controller performs step S84; if the first failure probability is not less than (including greater than or equal to) the first threshold, it is determined that the first chapter type does not match the first program type, the controller performs step S85 and step S86.

For example: assuming that the first threshold is 5%, the first program type is a music type, the first chapter type selected by the user is a music chapter, the first failure probability obtained by the lookup table 2 is 0.5%, and the first failure probability is smaller than the first threshold, and then it is determined that the music type program is matched with the music chapter.

Also for example: assuming that the first threshold is 5%, the first program type is sports type, the first chapter type selected by the user is advertisement chapter, the first failure probability obtained by the lookup table 2 is 92%, and if the first failure probability is greater than the first threshold, it is determined that the sports type program is not matched with the advertisement chapter.

Also for example: assuming that the first threshold is 5%, the first program type is a film and television type, the first chapter type selected by the user comprises a feature chapter and an advertisement chapter, the first failure probability a between the film and television type and the feature chapter is 0.5% obtained by the lookup table 2, the first failure probability b between the film and television type and the advertisement chapter is 4%, and since the first failure probability a and the first failure probability b are smaller than the first threshold, the film and television type program is matched with the feature chapter and the advertisement chapter.

In step S84, when the start execution time of the recording task is reached, the chapter content corresponding to the first chapter type in the target program is recorded.

The initial execution time is related to a recording mode set by a user, and if the user selects an immediate recording mode, the initial execution time is the time of successful creation of a recording task; if the user selects the reserved recording mode, the starting execution time is reserved recording starting time set by the user. For example, the program C is a music type, and the first chapter type selected by the user is a music chapter, and when the start execution time is reached, the controller records the chapter content of the music chapter included in the program C.

Step S85, controlling the display to display a first prompt page.

Fig. 9 is a schematic diagram of a first hint page according to some embodiments of the present application. Referring to fig. 9, the first hint page includes first hint information 91, a confirm switch button 92, and a cancel switch button 93. The first prompt message 91 is used to prompt that there is a recording failure risk, and prompt the user to switch the chapter type of the chapter to be recorded in the target program (may suggest to switch to the second chapter type). The first hint information 91 illustrated in fig. 9 is "the current program is of a music genre, and if the recording of the main chapter is selected, the recording is likely to fail, and the recording by the music chapter is recommended. The controller may set a second chapter type to which the user is recommended to switch before the first hint page is displayed by the display, thereby providing a basis for generating the first hint page.

In some embodiments, the controller may obtain a first set of probability information mapped by the first program type according to the probability relation table, the first set of probability information including probability information between the first program type and any chapter type, see table 1 or table 2, the first set of probability information including all probability information included in a row to which the first program type belongs. For example, the first program type is a music type, see Table 1, and an exemplary first set of probability information is { music chapters: normal; positive chapter, failure probability is high; advertisement section, failure probability is high; … }; referring to Table 2, another exemplary first set of probability information is { music chapter: failure probability 0.5%; positive chapter, failure probability 99%; advertisement section, failure probability 99%; … }.

In some embodiments, the controller may obtain a second chapter type corresponding to the smallest failure probability in the first set of probability information, and generate a first hint page, so that the first hint page provides a suggestion to switch to the second chapter type. For example, taking the first program type as a music type example, assume that the first set of probability information is { music chapter: normal; positive chapter, failure probability is high; advertisement section, failure probability is high; …, since both the feature chapter and the advertisement chapter are marked with a high probability of failure, the music chapter is marked as normal, the controller sets the second chapter type to be the music chapter.

For another example, when the first program type is a music type, assume that the first set of probability information is { music chapter: failure probability 0.5%; positive chapter, failure probability 99%; advertisement section, failure probability 99%; …, wherein the minimum failure probability is 0.5%, the minimum failure probability corresponds to a musical chapter, the controller sets the second chapter type to be a musical chapter. In this way it is possible to evaluate which scenes there is a risk of recording failure and to suggest at least one chapter type (i.e. the second chapter type) to switch to for the item markers that are at risk of recording failure in a probabilistic relationship table, e.g. table 1.

In some embodiments, the controller may obtain a second set of probability information for the first program type map according to the probability relation table, the second set of probability information including probability information between the first program type and candidate chapter types, wherein the candidate chapter types are chapter types having a failure probability with the first program type less than a first threshold, and the candidate chapter types may be one or more.

For example, assuming that the first program type is a movie type, referring to table 1, the failure probability of recording a music chapter is high, but a feature chapter and an advertisement chapter can be recorded normally, if the "failure probability high" is set to be the probability degree represented by a first threshold value, the failure probability of normal recording is smaller than the first threshold value, and an exemplary second probability information set is { feature chapter: normal; the advertisement chapter is normal, i.e. when the first program type is a film and television type, the candidate chapter types include a feature chapter and an advertisement chapter. Referring to Table 2, assuming a first threshold of 5%, another exemplary second set of probability information is { positive chapter: 0.5%; advertisement section 4% }.

For another example, assuming that the first program type is a shopping type, see table 1, the failure probability of recording a music chapter and a feature chapter is high, but an advertisement chapter can be recorded normally, an exemplary second probability information set is { advertisement chapter: normal }, i.e., the candidate chapter type includes an advertisement chapter. Referring to Table 2, assuming that the first threshold is 5% and the failure probability of a shopping type to an advertisement type is less than 5%, another exemplary second set of probability information is { advertisement section: 1% }.

Fig. 10 is a schematic diagram two of a first hint page according to some embodiments of the present application. Referring to fig. 10, a first hint page of another example includes: the second hint information 94, a second selection button 95 corresponding to the candidate chapter type included in the second set of probability information, a confirm selection button 96, and a cancel selection control 97. The second prompting information 94 is used for prompting that recording failure risk exists, and prompting a user to select at least one second chapter type from the candidate chapter types. The second prompt message 94 illustrated in fig. 10 is "the current program is of the movie type", if the recording of the music chapter is selected, the recording is easy to fail, please reselect the recordable chapter type (note: multi-selectable) ", and the first prompt page includes two second selection buttons 95 corresponding to the feature chapter and the advertisement chapter respectively. The user may select any one or more of the second selection buttons 95 to select a second chapter type, and when the confirmation selection button 96 is triggered, the controller records the chapter content corresponding to the second chapter type selected by the user in the target program, and when the deselection control 97 is triggered, the controller records the chapter content corresponding to the original first chapter type in the target program.

Step S86, judging whether the operation of switching to the second chapter type by the user is received.

In some embodiments, referring to fig. 9, after browsing the first prompt 91, if the user wants to increase the possibility of successful recording, the user clicks the confirm switch button 92 to make the controller receive the operation of switching to the second chapter type; conversely, if the user wants to maintain the selection of the original first chapter type, the cancel switch button 93 may be clicked so that the controller does not receive an operation to switch to the second chapter type.

In some embodiments, referring to fig. 10, after browsing the second prompt 94, if the user wants to maintain the selection of the original first chapter type, he clicks the deselect control 97, so that the controller does not receive the operation of switching to the second chapter type; if the user wants to increase the probability of successful recording, at least one second selection button 95 is selected, and then the confirm selection button 96 is clicked, the controller receives an operation to switch to the second chapter type.

If the controller does not receive the operation of switching to the second chapter type, executing step S84; if the controller receives the operation of switching to the second chapter type from the user, step S87 is performed.

Step S87, saving the second chapter type switched to by the user based on the first prompt page, and recording chapter content corresponding to the second chapter type in the target program when the starting execution time of the recording task is reached.

After the user selects the first chapter type, the display device may evaluate the failure risk when recording the target program according to the chapter according to the matching between the program type and the selected chapter type. If the program type is matched with the chapter type, the recording success is high, and the target program is recorded according to the first chapter type selected in advance. If the program type is not matched with the chapter type, the recording failure probability is high, the controller triggers a recording failure risk reminding mechanism, the display is controlled to display a first prompt page, and the user is recommended to switch to recording the target program according to the second chapter type.

In some embodiments, assuming that the program contains M chapter types, the number of selected chapter types (first chapter type or second chapter type) of the user is N, M may be greater than, equal to, or less than N. If M is greater than N, this indicates that the program covers more chapter types than the user selects. For example, the program a includes chapter 1 (advertisement), chapter 2 (feature film), chapter 3 (music), chapter 4 (feature film) and chapter 5 (advertisement) distributed according to the playing time sequence, that is, the program a includes 5 chapter contents (i.e., m=3) in total of 3 chapter types, if the selected chapter type of the user is only feature film chapter (i.e., n=1), the controller ignores chapter 1, chapter 3 and chapter 5 in the code stream when recording the program a, and the user may miss recording other more types of chapter contents because the user cannot predict the chapter number and chapter type included in the program a, and thus cannot play back the complete chapter of the program a.

Fig. 11 is a flowchart of a second program recording method according to some embodiments of the present application. To overcome the technical defect that exists when the target program contains more chapter types than the user's selected chapter types (i.e., M > N), referring to fig. 11, another program recording method is provided in the embodiments of the present application, which includes:

Step S111, when recording the target program, obtains chapter classification information from the code stream of the target program.

In some embodiments, the chapter classification information includes M chapter types that the target program contains, M+.1. The chapter classification information may also include the chapter number K, k+_m, and define the distribution of M chapter types/K chapters over the playback timing, e.g., chapter classification information indicates that program D includes chapter 1 (commercial), chapter 2 (feature) and chapter 3 (commercial) in that order.

In some embodiments, the operator may configure M chapter types/K chapters included in the target program and distribution of the M chapter types/K chapters on the playing time sequence, so as to generate chapter classification information, and transmit the chapter classification information to the display device along with the code stream of the target program synchronously through the server or the signaling device. In this way, the controller can compare the chapter classification information with the chapter type selected by the user, and if the chapter type range covered by the chapter classification information exceeds the chapter type selected by the user, the chapter type (i.e. a non-selected chapter type, hereinafter referred to as a third chapter type) which is not selected by the user is included in the target program.

In some embodiments, the operator may sequentially transmit the chapter code streams to the display device according to the time sequence distribution of the chapters, where each chapter code stream includes a chapter type of the current chapter. For example, the server or signaling device first transmits chapter 1 of program D to the display device and indicates that chapter 1 is an advertising chapter; after the transmission of the chapter 1 is finished, continuing to transmit the chapter 2 of the program D to the display equipment, and indicating that the chapter 2 is a feature chapter; after the transmission of the chapter 2 is finished, the chapter 3 of the program D is continuously transmitted to the display equipment, and the chapter 3 is indicated to be an advertising chapter. Thus, the display device side records the distribution of 2 chapter types/3 chapters in the program D, for example, advertisement chapter 1→feature film chapter 2→advertisement chapter 3, according to the chapter receiving timing, thereby obtaining chapter classification information of the program D. And each time the controller receives a section of chapter code stream, the chapter type corresponding to the chapter code stream can be identified, whether the chapter type is consistent with the chapter type selected by the user or not is judged, and whether the target program contains a third chapter type which is not selected by the user or not and whether the chapter code stream is recorded or not is further determined.

Step S112, judging whether the target program contains a third chapter type.

If the target program does not contain the third chapter type, step S113 is performed; if the target program contains a third chapter type, step S114 is performed.

Step S113, continuing recording the chapter content corresponding to the selected chapter type in the target program.

Step S114, the display is controlled to display a second prompt page.

Fig. 12 is a schematic diagram of a second prompting page provided in some embodiments of the present application, where the second prompting page is mainly used for prompting a user to add a third chapter type to supplement and record chapter contents corresponding to the third chapter type, so as to avoid missing recording and playback of the third chapter type when the user cannot predict the chapter type included in the program. Referring to fig. 12, the second hint page may include third hint information 121, a first confirm button 122, and a first cancel button 123. The third prompting information 121 is used for prompting that the third chapter type exists in the target program, and suggesting that the user adds the third chapter type to the selected chapter type. The third hint information 121 illustrated in fig. 12 is "you have selected to record a feature chapter and an advertisement chapter of the current program, but the current program also contains a music chapter, suggesting that you increase the recording of the music chapter".

In some embodiments, the second alert page may set a timeout mechanism, such as when the display is displaying the second alert page, the controller starts a timer that is used to detect the display duration of the second alert page. When the display duration of the second prompting page reaches the first preset duration (for example, 30 seconds), if the user does not click the first confirm button 122 and the first cancel button 123, a first response timeout event is triggered, and the controller may control the display to close the second prompting page, so as to avoid influencing the viewing or operation of the user when the second prompting page is continuously displayed for a long time.

Step S115, determining whether the user clicks the first confirm button within the first preset time period.

In some embodiments, the user may click the first confirm button 122 for a first preset duration if agreeing to add the third chapter type. If the controller receives the operation of clicking the first confirm button 122 from the user within the first preset duration, step S116 is executed; if the controller does not receive the operation of clicking the first confirm button 122 by the user within the first preset time period, step S117 is performed.

And step S116, controlling the display to close the second prompt page, storing chapter classification information and recording chapter contents corresponding to the third chapter type.

The purpose of storing chapter classification information is: and recording the distribution of M chapter types/K chapters contained in the target program on a playing time sequence, and generating a chapter catalog page according to the chapter classification information when a user plays back the recorded file of the target program so as to enable the user to rapidly request the interested chapter content according to the chapter catalog page. Because the user adds the third chapter type into the selected chapter type, the controller does not skip the third chapter type, so that chapter contents corresponding to the third chapter type can be recorded, the user can view more and more complete chapters of the target program, and the situation that the user can not predict the chapter type contained in the program to miss recording and playback of the third chapter type is avoided.

Step S117, judging whether the user clicks the first cancel button within the first preset time period.

In some embodiments, if the user wants to maintain the selection of the original chapter type without adding the third chapter type, the user may click the first cancel button 123 for a first preset duration. If the controller receives the operation of clicking the first cancel button 123 by the user within the first preset time period, step S118 is performed.

If the controller does not receive the operation of clicking the first cancel button 123 by the user within the first preset duration, that is, the user does not click the first confirm button 122 and the first cancel button 123 within the first preset duration, in consideration of that the user may not look up the second prompt page and further cause response timeout, in this embodiment, the controller defaults to execute step S116 under the condition that the response of the second prompt page is timeout.

Step S118, the display is controlled to close the second prompt page, chapter classification information is not saved, chapter contents corresponding to the selected chapter type in the target program are continuously recorded, and chapter contents corresponding to the third chapter type are not recorded.

The embodiment of the method illustrated in fig. 8 is to pre-evaluate the recording failure risk according to the program type and the selected chapter type of the user before recording the program, and prompt the user to switch to the chapter type with higher recording success through the first prompt page if the program type does not match the selected chapter type. In the embodiment of the method illustrated in fig. 11, after the recording task is started, it is determined whether to expand the chapter types of the program recording according to the program code stream, the chapter classification information and the user's wish, so as to avoid missing the recording and playback of the third chapter type due to the fact that the user cannot predict the chapter types included in the program, and further improve the recording function and user experience.

Fig. 13 is a flowchart of a program recording file playback method according to some embodiments of the present application. Based on the foregoing second program recording method, referring to fig. 13, a program recording file playback method includes:

step S131, an operation of playing back the recorded file of the target program by the user is received.

In some embodiments, the controller may create a corresponding folder in the target disk according to the program information of the target program, so that the user can conveniently view the recorded file stored in the folder, and play back the target chapter in the recorded target program according to the viewing desire. When the user plays back the target chapter, the controller may activate the media player, which reads and plays the recorded file of the target chapter from the target disk.

In some embodiments, the so-called "operation of playing back the recorded file of the target program by the user" in the embodiments of the present application may include, but is not limited to: the user clicks the operation of the folder corresponding to the target program in the target disk, the operation of the record playback button configured on the control device 100, the user inputs a voice command to play back the recorded target program, the operation of the record playback control configured on the user interface, and so on.

Step S132, judging whether the chapter classification information is stored in advance.

If the controller did not save chapter classification information previously, it may include the following cases: in the first case, the chapter type range included in the target program does not exceed the chapter type selected by the user; in the second case, the target program contains chapter types whose range exceeds the selected chapter type of the user, and the user clicks the first cancel button 123 in the second prompting page within the first preset time period.

If the controller has previously saved chapter classification information, it may include the following cases: in the first case, the chapter type range included in the target program exceeds the chapter type selected by the user, and the user clicks the first confirm button 122 in the second prompt page within the first preset duration; in case two, the target program contains chapter types that exceed the selected chapter type of the user, and the user does not click the first confirm button 122 and the first cancel button 123 for a first preset period of time, resulting in a timeout in response after the second prompt page is displayed.

If the controller does not store the chapter classification information before, executing branch logic I; if the controller has previously saved chapter classification information, branch logic two is executed.

Wherein, the branching logic one includes the following steps S133 and S134:

step S133, controlling the first chapter catalog page of the display.

In step S134, in response to the user clicking the first chapter playback control, the display is controlled to display the chapter content mapped by the first chapter playback control.

Fig. 14 is a schematic view of a first chapter catalog page provided in some embodiments of the present application. Referring to fig. 14, the first chapter catalog page includes at least one first chapter playback control 141 that is generated from the selected chapter type and recorded chapter content.

In some embodiments, for example: the carrier configured program S includes chapter 1 (advertisement), chapter 2 (feature), chapter 3 (music), chapter 4 (feature), chapter 5 (music), and chapter 6 (advertisement) distributed at the play timing, assuming that the selected chapter type of the user includes the advertisement chapter and feature chapter and the user has cancelled the recording of the added music chapter, the in-scene controller does not save chapter classification information of the program S and does not record chapter 3 and chapter 5 in the program S.

Referring to the example of fig. 14, the first chapter catalog page includes a first chapter playback control a, a first chapter playback control B, and a first chapter playback control C. Wherein the first chapter playback control a corresponds to the original chapter 1 (advertisement); after skipping the recording of the original chapter 3 (music) and the original chapter 5 (music), the original chapter 2 and the original chapter 4 are converted into adjacent chapters of the same type (both are feature chapters), and the controller can splice the original chapter 2 and the original chapter 4 into a new chapter 2, and the first chapter playback control B corresponds to the new chapter 2 (feature film); the first chapter playback control C corresponds to a new chapter 3 (advertisement), which is the original chapter 6 (advertisement). In this way, the user may optionally select the first chapter playback control corresponding to the chapter of interest, e.g., the user clicks on the first chapter playback control B, and the controller starts the media player, which reads and plays the recorded file of the new chapter 2 from the target disk.

The second branching logic includes the following steps S135 to S1311:

step S135, the display is controlled to display a third prompt page.

Fig. 15 is a schematic diagram of a third hint page according to some embodiments of the present application. Referring to fig. 15, the third hint page includes fourth hint information 151, a second confirm button 152, and a second cancel button 153. Wherein the fourth prompt 151 primarily prompts the user to view a chapter catalog including a complete chapter type (i.e., including a third chapter type and a selected chapter type of the user). The fourth cue information 151 illustrated in fig. 15 is "the current program has a chapter type that is not selected for recording by you, and it is recommended to switch to a more detailed chapter directory".

In some embodiments, the third hint page may set a timeout mechanism, such as when the display is displaying the third hint page, the controller starts a timer that is used to detect the duration of display of the third hint page. When the display duration of the third prompting page reaches a second preset duration (for example, 5 seconds), if the user does not click the second confirm button 152 and the second cancel button 153, a second response timeout event is triggered, and the controller may control the display to close the third prompting page, so as to avoid influencing the viewing or operation of the user when the third prompting page is continuously displayed for a long time.

Step S136, judging whether the user clicks the second confirm button within a second preset time period.

In some embodiments, the user may click the second confirm button 152 for a second preset duration if he wants to view a more detailed chapter catalog. If the controller receives the operation of clicking the second confirm button 152 from the user within the second preset time period, step S137 and step S138 are executed; if the controller does not receive the operation of clicking the second confirm button 152 by the user within the second preset time period, step S139 is performed.

In step S137, the display is controlled to close the third prompting page and display the second chapter catalog page.

In step S138, in response to the user clicking on the second chapter playback control, the display is controlled to display the chapter content mapped by the second chapter playback control.

Fig. 16 is a schematic diagram of a second chapter catalog page provided by some embodiments of the present application. Referring to fig. 16, the second chapter catalog page includes at least one second chapter playback control 161, the second chapter playback control 161 being generated from chapter classification information and recorded chapter content.

In some embodiments, for example: the operator configured program S includes chapter 1 (advertisement), chapter 2 (feature), chapter 3 (music), chapter 4 (feature), chapter 5 (music), and chapter 6 (advertisement) distributed in the play timing, assuming that the user' S previous selected chapter type includes only the advertisement chapter and feature chapter, and then the user confirms to increase recording of the music chapter based on the second hint page, the in-scene controller holds chapter classification information of the program S, and increases chapter 3 and chapter 5 in the recorded program S.

Referring to the example of fig. 16, the second chapter catalog page includes a second chapter playback control a, a second chapter playback control B, a second chapter playback control C, a second chapter playback control D, a second chapter playback control E, and a second chapter playback control F based on chapter classification information. The second chapter playback control a corresponds to chapter 1 (advertisement), the second chapter playback control B corresponds to chapter 2 (feature film), the second chapter playback control C corresponds to chapter 3 (music), the second chapter playback control D corresponds to chapter 4 (feature film), the second chapter playback control E corresponds to chapter 5 (music), and the second chapter playback control F corresponds to chapter 6 (advertisement).

Compared with the first chapter catalog page illustrated in fig. 14, the second chapter catalog page includes more detailed and complete chapter classification information, so that a user can clearly know the number and the chapter types of chapters included in a current program and the arrangement of chapters on a playing time sequence, and better guidance is provided for playback of program chapters by the user.

The method can show more detailed chapter catalogues to users, expand the range of playable chapters so that the users can select interested chapters, solve the problem of recording and playback of the missed possibly interested chapters caused by the fact that the users cannot predict the types of the chapters contained in the program, and promote recording functions and user experience.

Step S139, determining whether the user clicks the second cancel button within the second preset time period.

In some embodiments, the user may click the second cancel button 153 for a second predetermined duration while reviewing the program recording file if he does not want to view a more detailed chapter catalog, but instead simply views a chapter catalog containing a previously selected chapter type. The controller receives the operation of the user clicking the second cancel button 153 for a second preset time period, and performs steps S1310 and S1311.

If the controller does not receive the operation of clicking the second cancel button 153 by the user within the second preset duration, that is, the user does not click the second confirm button 152 and the second cancel button 153 within the second preset duration, in consideration of that the user may not view the third prompt page and thus cause response timeout, in the embodiment of the present application, the controller may execute step S137 and step S138 under the condition that the response of the third prompt page is timeout.

In step S1310, the display is controlled to close the third prompting page and display the first chapter catalog page.

In step S1311, in response to the user clicking on the first chapter playback control, the display is controlled to display chapter content mapped by the first chapter playback control.
