In some embodiments, if the display device supports a voice function, such as the voice interaction scenario illustrated in fig. 6, when the display device plays a television program, the user speaks "i want to record video" to the display device, and after the display device collects the voice information, the display device analyzes the voice information, for example, performs keyword extraction, semantic processing, and so on, so that it can be known that the voice intention of the user is to start the video function.

In some embodiments, in response to an intent instruction by the user to initiate a video recording function, a recording task setting page as illustrated in fig. 7 is displayed having a recording mode setting control 71, a first confirmation control 72, a first cancel control 73, and a disk selection control 74 therein, the user selecting a desired recording mode through the recording mode setting control 71.

In some embodiments, the recording modes include, but are not limited to, a time-by-time recording mode and a program-by-program recording mode. Referring to fig. 7, after the user selects the time recording mode, a time setting control 711 is displayed in the recording task setting page, and the user sets the start time T through the time setting control 711 ₀ And a stop time T _S Start time T ₀ And a stop time T _S The difference value of (2) is the preset recording time, and then the user triggers the first confirmation control 72, and the controller is started according to the starting time T ₀ And a stop time T _S Video recording tasks corresponding to a time recording mode are created.

In some embodiments, after the user triggers the disk selection control 74, a disk list is generated and displayed according to the connection state of the disk port, where the disk list includes related information of the currently available disk, including, but not limited to, a disk name, a remaining available memory/memory capacity of the disk, and other information, for example, for "U disk, 30G/64G", which indicates that the memory capacity of the U disk is 64G, 34G is used, the remaining available memory is 30G, and the user selects a disk from the disk list as a preset memory to store the video file.

In some embodiments, referring to fig. 8, after the user selects the program recording mode, the first confirmation control 72 is triggered, and then the controller queries the current program information according to the EPG (Electrical Program Guide, electronic program guide), the program information including a program name and a program play start-stop point, wherein the program name is used to indicate which program of which channel, the program play start-stop point is used to indicate the program on-time and the play stop time, and the controller creates a video recording task corresponding to the program recording mode according to the current program information.

In some embodiments, as shown in fig. 7 and 8, no video recording task is created if the user triggers the first cancel control 73, regardless of whether the user selects the recording mode, returning to the program play interface illustrated in fig. 5.

In some embodiments, if the time recording mode is adopted, the controller detects that the system time reaches the start time T of the video recording task ₀ The video recording task is started to be executed, and the display device displays a video recording interface, as in the example of fig. 9, where the video recording interface is not limited to displaying recording state prompt information 91, recorded time 92, recordable time 93 of a disk, pause control 94, stop recording control 95, progress bar 96, and the like, so as to realize "recording while broadcasting".

In some embodiments, the recording status prompt 91 is presented as a status prompt such as "recording," "recording completed," etc.; recorded time 92 is used to characterize the duration of time that the video has been recorded, and is timed from zero; the disc recordable time 93 is used for representing the duration that the disc can support video recording, and is generally related to the remaining available memory of the disc, recording speed, code stream resolution and other factors; the user can pause the recording process by triggering the pause control 94 once, the recorded time and the recordable time of the magnetic disk are kept unchanged temporarily, and when the user triggers the pause control 94 twice, the pause mode can be released, and the subsequent recording is continued from the current progress; the progress bar 96 is used to characterize the recording process and to facilitate user identification of whether the disc is full.

In some embodiments, if the recording mode is selected to record by time, the system time is detected to reach the stop time T of the video recording task _S Immediately stopping executing video recording taskThe method comprises the steps of carrying out a first treatment on the surface of the Or, whether the recording mode selects to record according to time or according to program, if the user actively triggers the stop recording control 95, the video recording task is immediately stopped.

In some embodiments, the controller responds to a recording stopping instruction, and stops executing the video recording task, that is, stops continuously buffering the code stream data, switches the state of the display device from "broadcasting while recording" to "broadcasting only without recording", changes the recording state prompting information 91 from "recording to" recording end "referring to the example of fig. 10, and displays a first query popup 97, where the first query popup 97 includes a first query information 971, a first storage control 972 and a first cancel control 973, and the first query information 971 is used for querying whether to store the video file, and if the user triggers the first cancel control 973, the buffered code stream data is deleted and the video file recorded this time is not stored; if the user triggers the first save control 972, the video file is saved to the specified disk, so that the user can conveniently access the disk and review the video file.

In some embodiments, if the program recording mode is adopted, the video recording task is immediately started, and the display device displays the video recording interface as illustrated in fig. 9 until the system time is detected to reach the play deadline of the current program, or until the user actively triggers the stop recording control 95 to stop executing the video recording task, and inquires whether to save the video file according to the example of fig. 10.

In some embodiments, the time-by-time recording mode and the program-by-program recording mode are independent and incompatible, and a user must select one recording mode when creating a video recording task. For the time recording mode, although the user is supported to arbitrarily and flexibly set the start time T ₀ And a stop time T _S However, if the recording time is long, the data size of the video file will be large, and the display device may play multiple programs during the recording period, referring to the example of fig. 11, assume that in the video recording task created by the user, the starting time T ₀ 19:00, stop time T _S When the controller detects that the system time reaches 19:00, the controller starts to execute the video recording task and starts to buffer the code stream number, wherein the system time is 20:00According to the method, recording is stopped until the system time reaches 20:00, in a recording period of 19:00-20:00, the program which is recorded while broadcasting comprises a program A, a program B and a program C which are continuously broadcast, wherein the playing time length of the program A is 30 minutes, the playing time length of the program B is 5 minutes, the playing time length of the program C is 25 minutes, namely, the playing starting and stopping points of the program A are 19:00 and 19:30, the playing starting and stopping points of the program B are 19:31 and 19:35, and the playing starting and stopping points of the program C are 19:36 and 20:00.

In the recording scenario illustrated in fig. 11, the controller reaches the stop time T upon detecting the system time _S If the video recording task is 20:00, stopping executing the video recording task, inquiring whether to store the video file according to the mode of fig. 10, if a storage instruction input by a user is received, storing the whole video file with the time length of 1 hour by the controller, wherein the video file contains three program videos played in the period of 19:00-20:00, and the interest preference of the user for each program is different, and the user can position favorite program fragments from one long video file by natural pushing of a playing process or complicated operations such as fast forwarding, seek and the like. For example, the user does not interest in the program a, the user may watch the program a first until the playing process naturally advances to 31 minutes, so as to continue watching the interested program B, or the user quickly jumps the playing progress to 31 minutes through operations such as fast forward or seek, so as to accelerate the skipping of the program a which is not interested.

Therefore, on one hand, a user wants to locate the interested program position from the long video files containing multiple programs, especially for video files with larger data volume and time length, the purpose can be long in time consumption and complex in operation when being realized; on the other hand, long video files may contain one or more program videos that are not of interest to the user, which wastes disk storage space; in addition, as shown in the example of fig. 12, at the end of the time recording mode, the controller responds to the save instruction input by the user, queries the channel information played by the display device during recording, names the video files by default by channel names in the time recording mode, and stores the video files containing at least one program video in a preset memory, wherein the preset memory is a magnetic disk for saving the video files, such as a local magnetic disk, a usb disk, a mobile hard disk, etc., for example, in fig. 12, the video file 1 and the video file 2 are named by the channel 1, and it is difficult for the user to distinguish whether the user wants to review the video file 1 or the video file 2.

In some embodiments, as in the example of fig. 13, when the program recording mode is finished, the controller responds to the save instruction input by the user, queries the program information played by the display device during recording, names the video files by default according to the program name in the program recording mode, and stores the video files containing only one program video in the preset memory, and the video files in the scene have high identification degree, so that the user can conveniently and quickly search the program video which wants to review. However, according to the program recording mode, only one program video can be recorded at a time, and if a plurality of program videos are to be recorded, a plurality of video recording tasks must be reserved in advance, so that the use of users is inconvenient.

In some embodiments, to overcome the drawbacks of the time-based recording mode and the program-based recording mode, the present application provides a scheme of merging time-based recording with program-based saving mode, creating and executing video recording tasks in the time-based recording mode according to the above procedure, and the controller reaches the stop time T when the controller detects that the system time reaches the stop time T _S Or when the user actively triggers the stop recording control 95, the controller responds to the stop recording instruction to stop executing the video recording task, and the controller is based on the starting time T ₀ And a stop time T _S And inquiring program playing information of the display equipment in the recording period from the EPG function in the limited recording period, wherein the program playing information comprises N pieces of program information, N is greater than or equal to 1, the program information comprises a program name and a program playing starting point, then determining a target storage mode of the video file according to the program playing information, and storing the video file in a preset memory according to the target storage mode.

In some embodiments, according to the foregoing procedure, when the user triggers the first save control 972 in fig. 10, the controller responds to the save instruction, and if N is equal to 1, i.e. only one program video is recorded in the recording time, the controller automatically stores the video file in the preset memory in the whole-segment save mode. The whole-section storage mode is configured to not divide the video file, name the video file according to the channel played by the display device in the queried recording period, and store the whole-section video file into the preset memory.

In some embodiments, according to the foregoing procedure, the user triggers the first save control 972 in fig. 10, and the controller responds to the save instruction, and if the program playing information is queried to include a plurality of program information, i.e., N is greater than 1, as in an example of fig. 14, a first save mode query pop 140 is displayed on the user interface, where the first save mode query pop 140 includes the first prompt 141, the first mode control 142, and the second mode control 143. The first prompt information 141 is used for prompting a user to select a storage mode of a video file; when the first mode control 142 is triggered, the controller stores the video file in the preset memory in a whole-segment storage mode, that is, the video file is not divided according to the programs, and the whole-segment video file contains N program videos.

In some embodiments, when the second mode control 143 is triggered, the controller stores the video file in the preset memory in a program save mode configured such that the start of program play indicated by each program information is T _{i_1} And the program playing dead point is T _{i_2} I represents the program sequence number after the programs in the recording time interval are sequenced according to the playing time sequence, i is more than or equal to 1 and less than or equal to N, the video file is divided into N program recording subfiles, the N program recording subfiles are respectively named according to the program names, and then the N program recording subfiles are stored in a preset memory.

In some embodiments, the controller queries [ start time T ] according to the EPG function in response to a trigger instruction to the second mode control 143, referring to sub-graph (a) of fig. 15 ₀ Stop time T _S ]In the recording period, 3 programs (i.e., n=3) are continuously broadcast according to the time sequence, namely program a, program B and program C, wherein the broadcasting start and stop points of program a are respectively T _{1_1} And T _{1_2} The playing start and stop points of the program B are respectively T _{2_1} And T _{2_2} The playing start and stop points of the program C are respectively T _{3_1} And T _{3_2} Based on the playing continuity of a plurality of programs in the same channel in time, the dead points and the starting points of two adjacent programs coincide, namely, T is satisfied ₀ Equal to T _{1_1} ，T _{1_2} Equal to T _{2_1} ，T _{2_2} Equal to T _{3_1} ，T _{3_2} Equal to T _S Thus according to T _{1_1} And T _{1_2} Dividing subfiles I corresponding to the program A from the whole video file, and according to T _{2_1} And T _{2_2} Dividing a subfile II corresponding to the program B from the whole video file, and according to T _{3_1} And T _{3_2} And dividing a subfile III corresponding to the program C from the whole video file. As in sub-graph (B) of fig. 15, the first sub-file, the second sub-file and the third sub-file are respectively stored in the preset memory, wherein the first sub-file is named as the name of the program a, the second sub-file is named as the name of the program B, and the third sub-file is named as the name of the program C, and the program names may include channel names, for example, the program names are channel 1-program a, or may be presented as program a only, and not include channel names.

In some embodiments, the program play/record timeline, as shown in FIG. 16, is at T ₀ At the time node, the controller starts to execute the video recording task, starts to buffer the code stream data, and at T _{1_2} Program 1 recording at time node is cut off, recording of the next program is continued, and so on, at T _{i_1} Beginning recording program i at time node, at T _{i_2} Recording of program i at time node is cut off, when system time reaches T _S When the time node is time node, stopping executing the video recording task, and starting from T ₀ To T _S During the recording period, the recording process traverses N programs, and N program information is ordered according to the playing time sequence on the time axis, wherein the playing starting point of the program corresponding to the initial program information (namely the program 1) ordered at the first position is T _{1_1} And the program playing dead point is T _{1_2} The program playing starting point corresponding to the ending program information (namely the program N) ordered at the last position is T _{N_1} And the program playing dead point is T _{N_2} Referring to FIG. 16, if T ₀ Greater than T _{1_1} When the video recording task is started, a part of video clips are broadcast in the program 1, and the video clips are recorded in the program 1T ₀ As the recording start point of program 1, according to T ₀ And T _{1_2} Dividing a subfile 1 of the program 1, wherein the recording of the program 1 is incomplete in the scene; if T _S Less than T _{N_2} When the video recording task is finished, if the program N is not yet played, T is set _S As recording stop point of program N, according to T _{N_1} And T _S And dividing a subfile N of the program N, wherein the recording of the program N is incomplete in the scene. The other programs 2 to N-1 can ensure complete recording.

The scheme uses individual programs as units to divide and store video files, and after the user accesses a preset memory, the user can quickly search for interesting program videos and delete uninteresting program videos, thereby avoiding the waste of disk storage space.

In some embodiments, according to the foregoing procedure, the user triggers the first save control 972 in fig. 10, and then the controller responds to the save instruction, and if it is queried that the program play information includes a plurality of program information, i.e., N is greater than 1, as another example in fig. 17, a second save mode query pop 170 is displayed on the user interface, where the second save mode query pop 170 includes a second prompt 171, an agreeing control 172, and a reject control 173, and the second prompt 171 is used to query whether to agree to use the save by program mode, and the second prompt 171 in fig. 17 is illustrated as "whether to agree to save by program video file? If the user triggers the consent control 172, the controller responds to the consent instruction to save the video file in program save mode; if the user triggers the reject control 173, the controller saves the video file in the full save mode in response to the reject instruction.

In some embodiments, in response to a stop recording instruction, if the program playing information is queried to include a plurality of program information, i.e. N is greater than 1, a third save mode query pop 180 as illustrated in fig. 18 is displayed on the user interface, the third save mode query pop 180 including a first save mode control 181, a second save mode control 182, and a no save control 183, the first save mode control 181 corresponding to a full segment save mode, the second save mode control 182 corresponding to a per program save mode. If the user triggers the not-save control 183, deleting the code stream data cached in the recording period, and not saving the video file; if the user triggers any one of the first saving mode control 181 and the second saving mode control 182, the current video file needs to be saved according to the saving mode corresponding to the mode control. In this embodiment, when stopping executing the video recording task, it is not necessary to inquire whether to save the video file first and then select the target saving mode, but the two modes are presented in the same popup page in a centralized manner, so as to simplify UI and user operation.

In some embodiments, if the video file contains a plurality of program videos that are continuously broadcast, because the interest preference of the user for each program is different, the user is more expected to keep the program videos that are interested by the user, and filter or delete the program videos that are not preferred by the user, and in this way, after the user selects the program storage mode according to the storage mode query popup illustrated in fig. 14, 17 and 18, the controller controls the display to close the storage mode query popup, and displays the program storage page 190 illustrated in fig. 19 on the user interface, and the program information of the recorded N programs is presented to the user in the program storage page 190, where the program information at least includes the program names for the user to identify and filter. The user can select M pieces of target program information from N pieces of program information according to own interest preference, wherein the M pieces of target program information form a first program set, M is more than or equal to 0 and less than or equal to N, and the rest M-N pieces of unselected program information form a second program set. The first set of programs is used to indicate programs that the user is interested in, and desired to be saved, and the second set of programs is used to indicate programs that the user is not interested in, and not desired to be saved.

In some embodiments, referring to fig. 19, each program information in program save page 190 corresponds to a selection control 191, and when selection control 191 is in the selected state, its corresponding program information is selected. Also included in program save page 190 are a second confirm control 192 and a second cancel control 193.

In some embodiments, if the user does not select any program information, i.e. after the null selection, the second confirmation control 192 is triggered, or the user triggers the second cancellation control 193, i.e. m=0, the first program set submitted by the user is an empty set, the second program set is a full set, which is equivalent to not storing a video file, and the controller deletes the code stream data cached in the recording period, i.e. presents the program video full deletion form.

In some embodiments, if M is greater than 0 and M is less than N, the first program set and the second program set are both non-empty proper subsets, the controller divides the whole video file into N program recording subfiles according to the program playing start and stop points indicated by the N program information, deletes the subfiles corresponding to each program information in the second program set (for convenience of distinguishing, the application names the subfiles as the second program recording subfiles), and names the subfiles corresponding to each program information in the first program set (for convenience of distinguishing, the application names the subfiles as the first program recording subfiles) according to the program names, and stores the M first program recording subfiles in a preset memory, that is, takes the forms of partial program recording and storage and the other partial program recording and deletion.

In some embodiments, referring to the example of fig. 20, the program saving page 190 displays four program information, i.e., n=4, namely, program a, program B, program C, and program D, respectively, the user clicks the selection control 191 corresponding to program a and program D, and then triggers the second confirmation control 192, where the first program set is { program a, program D }, the second program set is { program B, program C }, and after the video file is divided into four parts, i.e., the sub-file a, sub-file B, sub-file C, and sub-file D are sequentially divided, only the sub-file a and the sub-file D are stored in the preset memory, the sub-file a is named as the name of program a, the sub-file D is named as the name of program D, and the sub-file B and the sub-file C are deleted.

In some embodiments, referring to fig. 20, the program saving page 190 may further set a full selection control 194, if the user clicks all the selection controls 191, or the user triggers the full selection control 194 and then triggers the second confirmation control 192, M is equal to N, the first program set submitted by the user is a full set, and the second program set is an empty set, and then the controller divides the recording file into N program recording subfiles and names the N program recording subfiles respectively, and then stores all the N program recording subfiles into the preset memory without deleting any subfiles, i.e. the full storage form of the program recording is presented.

In some embodiments, if the video file is saved in the program save mode, the controller detects that the selected M program recording subfiles are all stored in the preset memory, and controls the display to prompt "the video file is saved successfully in the program save mode" in the user interface.

In some embodiments, if the video file is saved in the whole-segment save mode, the controller detects that the whole video file is stored in the preset memory, and controls the display to prompt "the video file is saved successfully" in the user interface. After the user checks the prompt information of successful video storage, the user can access the preset memory at any time to watch the video file.

In some embodiments, fig. 21 illustrates a method for saving video files, the method being performed by a controller of a display device, comprising the following program steps:

In some embodiments, fig. 22 illustrates another method of saving video files, the method being performed by a controller of a display device, comprising the program steps of:

in step S221, when the current time reaches the start time, the video recording task is started to be executed, so as to record the currently played program video in a time recording mode.

In step S222, in response to the recording stopping instruction, the video recording task is stopped to generate a video file.

Step S223, whether a save instruction is received. If a save instruction is received, step S224 is executed; if the save instruction is received, step S2212 is performed.

Step S224, inquiring the program playing information of the display device in the recording period, where the program playing information includes N pieces of program information.

Step S225, judging whether N is greater than 1. If N is greater, step S226 is performed; if n=1, step S2211 is performed.

Step S226, inquires whether the per program save mode is agreed. If the user agrees to adopt the program-by-program saving mode, step S227 is executed; if the user refuses to use the program-by-program saving mode, step S2211 is performed.

Step S227, according to the program playing start and stop points indicated by the N program information, the video file is divided into N program recording subfiles, and the program recording subfiles are named according to the program names.

Step S228, displaying a program storage page, wherein the N pieces of program information are displayed in the program storage page.

Step S229, receiving a selection operation for M pieces of target program information in the program storage page. M is less than or equal to N.

Step S2210, storing the first program recording subfiles corresponding to the M target program information into a preset memory, and deleting the second program recording subfiles corresponding to the unselected N-M program information.

Step S2211, the video file is named according to the current channel name without dividing the video file, and the video file is stored in a preset memory.

Step S2212, delete the video file.

In other possible implementations, as shown in the recording task setting page illustrated in fig. 23, the user selects the time recording mode to set the start time T ₀ And a stop time T _S After that, the controller inquires from the EPG that the current channel is at [ T ] ₀ ,T _S ]And if a plurality of programs are broadcast in the time interval, displaying a first switch control 231, wherein the first switch control 231 is used for controlling the on and off of an automatic program-saving function. The automatic program-by-program saving function includes two capabilities, one is to automatically save the video file without inquiring whether to save the video file when stopping recording, and the other is to automatically start the program-by-program saving mode without selecting a saving mode by a user.

In some embodiments, if the user switches the first switch control 231 to the on state, as shown in fig. 24, [ T ] is displayed in the recording task setting page ₀ ,T _S ]Program information contained in the current channel in the time period, the user selects the interested programs expected to be recorded from the program information, and all or part of the programs can be selected for storage. For example, the recording task setting page in fig. 24 shows program information of program 1, program 2 and program 3, respectively, the user selects program 1 and program 3, and then triggers the third confirmation control 234, and the controller is controlled according to the start time T ₀ Time of stop T _S Program information of the program 1 and the program 3, creating a video recording task, wherein the program information comprises a program name and a program playing starting point, and the playing starting point of the program 1 is set as T _{1_1} And the play dead point is T _{1_2} The playing start point of the program 3 is T _{3_1} And the play dead point is T _{3_2} . In some embodiments, the controller detects that the system time reaches the start-up time T ₀ Starting to execute video recording tasks, and continuously recording program 1, program 2 and program 3 according to time sequence until detecting that system time reaches stop time T _S Stopping executing the video recording task according to T ₀ And T _{1_2} Sub-file 1 of program 1 is split according to T _{3_1} And T _S Sub-files 3 of the program 3 are divided, then sub-files 1 and 3 are named and saved, respectively, and sub-files 2 of the separated program 2 are deleted.

In some embodiments, if the user selects program 1 and program 3, the controller detects that the system time reaches start-up time T ₀ Starting to execute video recording task, starting to record program 1 until detecting that system time reaches T _{1_2} When the recording of the program 1 is cut off, the video recording task can be immediately suspended, namely, the controller pauses the cache video code stream, at the moment, the display equipment is in a 'broadcast only and not recorded' state, the controller firstly carries out format conversion on the cache data of the program 1 to generate a sub-file 1, and the sub-file 1 is named and automatically stored in a preset memory. The controller detects that the system time reaches T _{3_1} Immediately releasing the pause state of the task, resuming recording of the program 3, generating a sub-file 3 until the recording is stopped, naming the sub-file 3 and automatically storing the sub-file 3 in a preset memory. According to the embodiment, by suspending the recording process and skipping the recording links of the unselected programs 2, the dynamic self-adaptive segmentation of the video file and the automatic filtering of the programs not interested are realized.

In some embodiments, referring to fig. 24, if the user selects program 2 and program 3, in order to skip the recording link of program 1 that is not interested by the user, the start time T of the video recording task may be set ₀ Back to the playing start point T of the program 2 _{2_1} Stop time T _S The time set for the user is kept unchanged, so that at [ T ] ₀ ,T _S ]During this recording time, only program 2 and program 3 are recorded.

In some embodiments, referring to fig. 24, if the user selects program 1 and program 2, to skip the recording link of program 3 that is not of interest to the user, the stop time T of the video recording task may be set _S Move forward to play dead point T of program 2 _{2_2} Start time T ₀ The time set for the user is kept unchanged, so that at [ T ] ₀ ,T _S ]During this recording time, only program 1 and program 2 are recorded.

In some embodiments, referring to fig. 24, if the user selects only program 2, the start time T of the video recording task may be set to skip the recording links of program 1 and program 3 that are not of interest to the user ₀ Back to the playing start point T of the program 2 _{2_1} Stopping time T of video recording task _S Move forward to play dead point T of program 2 _{2_2} I.e. automatically adjusting the start-up time T ₀ And a stop time T _S To accommodate the user's program preferences, at [ T ] ₀ ,T _S ]Recording only program 2 during this recording time corresponds to adjusting from the time-by-time recording mode to the program-by-program recording mode.

In some embodiments, if the user is not interested in program 1, program 2, and program 3, then the start-up time T may be reset ₀ And a stop time T _S Or trigger a third cancel control 235 to cancel the creation of the video recording task.

In some embodiments, if the user switches the first switch control 231 to the off state, the recording task setting page cancels the display [ T ] ₀ ,T _S ]After the user triggers the third confirmation control 234 after the program information contained in the current channel in the period, when recording is stopped, the controller controls the display to display the storage mode query popup window illustrated in fig. 14, 17 or 18, and controls the storage of the video file in response to whether to store or not and the related operation instruction of the storage mode input by the user.

In some embodiments, as shown in FIG. 25, if the user switches the first switch control 231 to the off state, the recording task setting page cancels the display [ T ] ₀ ,T _S ]Program information contained in the current channel in the time period, and displaying a second switch control 232, wherein the second switch control 232 is used for controlling the on and off of an automatic whole-segment storage function. If the user switches the second opening Guan Kongjian 232 to the closed state, when stopping recording, the controller controls the display to display the storage mode inquiry popup window illustrated in fig. 14, 17 or 18, and controls the storage of the video file in response to whether to store or not and the related operation instruction of the storage mode input by the user; if the user switches the second switch control 232 to the on state, the controller automatically stores the video file in the preset memory in the whole-section storage mode when stopping recording, and the display is not required to be controlled to display the storage mode inquiry popup.

In some embodiments, the controller queries the EPG for the current channel at [ T ] ₀ ,T _S ]Program playing information in time slot, if only one program is played in the time slot, as shown in fig. 26, recordingThe task setting page does not display any program information, and displays a third switch control 233, where the third switch control 233 is used to control the on and off of the function of automatically storing video files. If the user switches the third switch control 233 to the off state, when stopping recording, the controller controls the display to display the first query pop-up window 97 illustrated in fig. 10, and queries the user whether to save the video file; if the user switches the third switch control 233 to the on state, the recording is stopped, and the recording file is automatically stored in the preset memory without a popup window inquiring whether to store the recording file. By providing a switch control related to a storage function on the recording task setting page, the recording file can be automatically stored to a preset memory in a target storage mode when recording is stopped, and UI and user operation are simplified.

In some embodiments, the user may designate a storage path for storing the video file in a setting page or a recording task setting page related to the video recording function, that is, set a preset memory, where the preset memory may be a built-in disk of the user or may be an external removable disk (for example, a usb disk, a removable hard disk, a card reader, etc.). If the preset memory is an external movable disk, the external movable disk and the display equipment are in effective connection during video recording and video storage, and if the controller detects that the external movable disk is disconnected, the video recording task is interrupted, and a user is prompted to detect the disk connection. The preset memory may sort the video files according to rules such as the time of storage, the size of the file, the recording duration, the file name, etc., for example, the files are sorted according to descending order of the time of storage, that is, the more recently stored files are sorted earlier.

In some embodiments, the preset memory may report its own available memory to the controller in real time, and if the controller detects that the disk has no available memory or the preset memory is full, the controller immediately stops executing the video recording task and prompts the user that the disk is full; the controller detects that the system time reaches the starting time T ₀ If the preset memory is inquired that the available memory is unavailable, namely, the preset memory cannot continuously store the video file, the video recording task is not started to be executed, the user is prompted of information that the disk is unavailable and recording fails, and the user can reestablish the video recording task after cleaning the disk memory or switching the storage path of the video file. In addition, the controller calculates and updates the recordable time 93 of the disc shown in the video recording interface as illustrated in fig. 9 according to the available memory reported by the preset memory and in combination with parameters such as the resolution of the TV code stream.

In some embodiments, the user may create multiple video recording tasks, the controller may maintain a task queue, add video recording task a (to be performed) to the task queue every time a video recording task a is newly created, and remove video recording task B (performed) from the task queue every time a video recording task B is completed, and remove video recording task C (expired) from the task queue if video recording task C times out.

By the technical scheme, the display device can play only one channel program during recording, and can save video files in a whole-section saving mode; or a plurality of programs continuously played on the same channel are recorded, and then the whole video file is divided into a plurality of subfiles corresponding to independent programs according to a program storage mode and then stored, so that a user can conveniently and quickly review the recorded video of the program of interest; the application also supports discarding the recorded video of the program which is not interested by the user, and reduces the consumption of the disk memory.
