Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.
Referring to fig. 2, fig. 2 is an execution flowchart of the play progress adjustment method according to the embodiment of the present invention, and the play progress adjustment method according to the embodiment of the present invention can shorten the response time of the whole progress adjustment process. Specifically, the technical problem corresponding to the scheme can be caused because the user repeatedly sends the adjustment instruction for multiple times within a certain time, and therefore, in the preset time period, the smart television system receives at least two adjustment instructions sent by the remote controller. The first preset time may be set arbitrarily according to an actual operation requirement, for example, in an optional implementation manner of the present solution, the first preset time may be set to 10 s.
The method comprises two logic threads which do not interfere with each other to execute, namely an instruction storage thread and a positioning thread, wherein the instruction storage thread executes the step S101, calls the instruction storage thread, and executes and stores the operation of each adjusting instruction;
for the positioning thread, the following steps are executed:
step S102, after the first adjusting instruction starts to execute the positioning operation, receiving and storing a new adjusting instruction based on the instruction storage thread;
step S103, if the playing time indicated by the first adjusting instruction has finished the positioning operation, starting to execute the positioning operation of the playing time indicated by the new adjusting instruction;
step S104, otherwise, continuously waiting for receiving a new adjustment instruction, which is equivalent to returning to step S103 to determine whether the play time indicated by the first adjustment instruction ends the positioning operation, if so, starting to perform the positioning operation on the play time indicated by the new adjustment instruction, and performing the positioning operation on the play time indicated by the latest adjustment instruction stored in the instruction storage thread until the play time indicated by the first adjustment instruction ends the positioning operation.
Specifically, in an optional implementation manner of the present disclosure, based on the implementation scenario, referring to fig. 3, fig. 3 is an execution flowchart of a play progress positioning method for receiving multiple instructions for adjusting a play progress within a preset time of a terminal according to an embodiment of the present disclosure.
Starting to execute the method, the intelligent television system configures two execution threads and calls an instruction storage thread to execute the following operations: receiving and storing each adjusting instruction; meanwhile, calling a positioning thread to execute the following operations: and acquiring the playing time corresponding to the initial adjustment instruction, and executing positioning operation corresponding to the playing time.
It should be noted that the essence of the positioning operation is to analyze the audio/video code stream to obtain an audio/video key frame corresponding to the playing time, and further lock the key frame so that the key frame is displayed in the smart television system. Specifically, there are various operations for parsing the code stream to obtain the key frame, and all the operations are well known to those skilled in the art, and the embodiments of the present invention are not described in detail herein.
No matter the user repeatedly triggers the remote controller to send the adjustment instruction for many times or continuously triggers the remote controller to send the adjustment instruction, the smart television system usually firstly obtains the adjustment direction corresponding to the adjustment instruction, and then calculates according to a preset algorithm to obtain the playing time after responding to the adjustment instruction. In particular, since this process is well known to those skilled in the art, embodiments of the present invention will not be described in detail herein.
When a second adjustment instruction is received, which indicates that the user may need to adjust for a plurality of times to reach the required playing time, at this time, the instruction storage thread is called to execute the following operations: the adjustment instruction is always stored, and the playing time corresponding to the adjustment instruction is correspondingly stored. It should be noted that, in this scheme, the smart television system may sequentially store the playing time in one data table, or may create two data tables respectively having the first identifier and the second identifier when receiving the second adjustment instruction, and sequentially store the adjustment instruction and the playing time corresponding to the adjustment instruction in the data table corresponding to the first identifier.
In this embodiment, the data tables may be sequence tables capable of storing data, for example, stacks, and when two data tables are set, the two data tables are respectively used for storing the playing time of the adjustment instruction and providing the playing time to be located, and the two data tables are distinguished by the first identifier and the second identifier. The first identifier and the second identifier correspond to each other and may be two different character or number identifiers, for example, in an optional example of the present invention, the first identifier may be set to "move"; the first flag may be set to "play". The embodiment of the present invention is not limited thereto.
In addition, it should be noted that, generally, operations such as the playing time corresponding to the adjustment instruction are obtained, and the consumed time is relatively short, that is, the duration of the operation process is shorter than the duration of the positioning operation, so when the second adjustment instruction is received, the operation content of the positioning thread is still that the initial adjustment instruction performs the positioning operation corresponding to the playing time of the initial adjustment instruction. Based on this, further, when the positioning operation corresponding to the initial adjustment instruction is finished, the smart television system may have received multiple adjustment instructions, and each time an adjustment instruction is received, the instruction storage thread is invoked to perform the operation of receiving and storing the corresponding adjustment instruction.
Further, after the first positioning operation is finished, the smart television system reads the next play time to be positioned from the data table, and specifically, when the scheme is executed, the smart television system can read the currently latest stored play time and execute the positioning operation according to the latest stored play time.
Specifically, the stored data table corresponding to the playing time may be one or two or even more data tables, but different numbers of data tables, and the present solution is introduced below corresponding to two implementation scenarios, respectively, when reading the currently latest stored playing time and performing different positioning operation processes according to the latest stored playing time.
When the data table storing the adjustment instruction is a data table, sequentially storing the playing time indicated by each received adjustment instruction into the data table which is created in advance through an instruction storage thread, reading the playing time indicated by the newly stored adjustment instruction from the data table every time a new adjustment instruction is received and stored, starting to position the playing time indicated by the newly stored adjustment instruction in the data table if the positioning operation corresponding to the adjustment instruction at the previous time is ended, and continuing to wait for receiving the new adjustment instruction until the playing time indicated by the latest adjustment instruction stored in the instruction storage thread is ended and positioned; specifically, it may be determined whether the playing time indicated by the latest stored adjustment instruction is the same as the playing time of the adjustment instruction that was successfully positioned last time, and if the latest stored playing time is different from the playing time that was successfully positioned last time, it indicates that a new adjustment instruction was stored in the data table in the previous positioning process, so that the positioning operation is performed corresponding to the playing time indicated by the latest stored adjustment instruction, and after each positioning operation is completed, the above-described process is executed in a loop until the latest stored playing time is the same as the playing time that was successfully positioned last time, and the positioning is completed.
When the data table for storing the playing time is two data tables, two data tables respectively provided with a first identifier and a second identifier can be created in advance, and according to the operation content of the instruction storage thread, from the beginning of creating the current data table corresponding to the second identifier to the end of the first positioning operation, the smart television system never stores the playing time into the data table, and the playing time generated in the process of executing the positioning operation is stored into the current data table corresponding to the first identifier. Different from one data table, in this embodiment, when the first positioning operation is finished, the identifiers of the two data tables may be exchanged, the latest stored playing time is read again from the data table corresponding to the first identifier after the identifiers are exchanged (the data table is actually the data table with the second identifier before the exchange), and then the positioning operation is executed corresponding to the read playing time.
The two data tables can save the space occupied by data storage relative to one data table, and the data table corresponding to the first identifier can be emptied after each positioning is finished, so that the data volume is limited relative to the scheme of one data table, and the method belongs to the preferred embodiment.
It should be noted that, because the playing time indicated by the adjustment instruction stored in the data table is only the transition time from the starting playing time to the target playing time, in this embodiment, the smart television system may directly read the playing time indicated by the adjustment instruction stored in the data table most recently, and perform the positioning operation corresponding to the playing time.
Therefore, according to the scheme, the positioning operation is executed each time, and meanwhile, the adjusting instruction triggered by the operation of the remote controller by the user is stored continuously, for example, after the positioning operation is executed for one time, no matter how many adjusting instructions are stored, the positioning operation is executed only corresponding to the current latest playing time for the next time, and the playing time between the two positioning operations is not processed, namely, the positioning operation is not required to be executed corresponding to each playing time, so that the response time of the whole progress adjusting process can be shortened.
On the basis of the execution process, due to reasons such as that a program possibly appears falls into endless loop and the like, a positioning operation failure phenomenon can appear at a certain playing time.
Therefore, when the positioning fails corresponding to a certain playing moment, the method and the device can automatically select a proper playing moment to execute the positioning operation again, and accordingly normal adjustment of the playing progress can be guaranteed.
In addition, when the playing time has been adjusted to the starting time or the ending time of the video, and the direction corresponding to the next adjustment instruction is still the previous time of the starting time or the next time after the ending time, then, since the playing time corresponding to the adjustment instruction is still the starting time or the ending time of the video, the operation of storing the playing time may not be executed any more. Specifically, after the playing time corresponding to the nth adjustment instruction is obtained, the playing time corresponding to the (N-1) th adjustment instruction may be read, and it is detected whether the playing time corresponding to the nth adjustment instruction is the same as the playing time corresponding to the (N-1) th adjustment instruction, if the playing time corresponding to the nth adjustment instruction is the same as the playing time corresponding to the (N-1) th adjustment instruction, the playing time corresponding to the nth adjustment instruction is not stored, and if the playing time corresponding to the nth adjustment instruction is different from the playing time corresponding to the (N-1) th adjustment instruction, the operation of storing the. In this embodiment, N is a positive integer greater than or equal to 2.
Furthermore, because the time for the user to trigger the remote controller to send the adjustment instruction may be uncertain, after the positioning of the smart television system is finished, it may be determined whether a new adjustment instruction is currently received, if a new adjustment instruction is currently received, the above positioning process is repeatedly executed, and if a new adjustment instruction is not currently received, all stored data is emptied, or two data tables are deleted.
Therefore, after the positioning is finished, the scheme can be adjusted automatically according to different conditions, so that the scheme can be further optimized, and the use experience of a user is improved.
In addition, it should be noted that, when the existing schedule positioning method for receiving multiple instructions for adjusting the playing schedule in the terminal preset time is executed, the cursor in the player generally moves to the corresponding playing time in real time along with the adjustment instruction of the remote controller, but at this time, the system may perform the positioning operation at a certain playing time before the adjustment, for example, referring to fig. 1, the cursor moves to playing time a, playing time B, playing time C and playing time D sequentially along with the adjustment instruction, and when the cursor moves to playing time D, the system may perform the positioning operation corresponding to playing time a. Therefore, in the prior art, a cursor cannot clearly show the real progress which is adjusted to currently to a user, so that the use experience of the user is poor.
In view of this, please refer to fig. 4, fig. 4 is a schematic diagram of a first implementation manner of a play interface according to an embodiment of the present invention, in a technical solution of the embodiment of the present invention, when an initial adjustment instruction is received by a smart television system, an independent cursor in a player is split into a first sub-cursor 01 and a second sub-cursor 02, wherein when an operation of an instruction storage thread is executed, each time a new adjustment instruction is received, that is, each time a play time is obtained, the first sub-cursor 01 is controlled to move to a position in a progress bar of the player corresponding to the play time, and when an operation of a positioning thread is executed, each time a play time indicated by an adjustment instruction that executes a positioning operation is positioned, the second sub-cursor 02 is controlled to move to a play time corresponding to the corresponding positioning operation.
Namely, the implementation mode of the scheme can respectively indicate the playing time corresponding to the adjustment instruction and the actually positioned playing time through the two cursors, so that the current playing progress and the target progress can be more clearly determined, and the use operation of a user is further improved.
In order to make the technical staff more clear and understand the scheme in detail, the following describes the scheme with reference to the schematic diagram of the playing interface.
Assuming that in an embodiment of the present disclosure, a user wants to adjust the playing time from the playing time O to the playing time F in the playing interface, if the user repeatedly presses a key for rightward adjustment for multiple times, when the smart television system receives an initial adjustment instruction, the playing interface is as shown in fig. 4, which is not described here again.
Referring to fig. 5, in this embodiment, each adjustment instruction corresponds to a playing time from a playing time O to a playing time F, and the playing time a, the playing time B, the playing time C, and the playing time D will be experienced, and the playing time F can be reached only finally, when the initial adjustment instruction is received, the first sub-cursor 01 moves to the playing time a, and meanwhile, the smart television system acquires the playing time a and starts to perform positioning operation.
Referring to fig. 6, after the positioning operation is successfully performed corresponding to the playing time a, the second sub-cursor 02 is moved to the playing time a, during this time period, the user sends 3 adjusting instructions, the three adjusting instructions correspond to the playing time B, the playing time C, and the playing time D, respectively, and the first sub-cursor 01 is moved to the playing time B, the playing time C, and the playing time D in sequence. Then, the play time B, the play time C, and the play time D are sequentially stored in the data table from the reception of the adjustment instruction corresponding to the play time B. Therefore, the play time B, the play time C, and the play time D have already been stored in the data table after the positioning operation is successfully performed corresponding to the play time a.
Reading the latest stored data in the data table, namely, the playing time D, because the playing time D is different from the playing time A, the positioning is not finished yet, and then the positioning operation is continuously executed corresponding to the playing time D. Meanwhile, the user continues to send an adjustment instruction, the smart television system responds to the adjustment instruction, the first sub-cursor 01 is sequentially moved to the playing time E and the playing time F, after the adjustment instruction is received, the playing time E and the playing time F corresponding to the adjustment instruction are obtained, and the playing time E and the playing time F are stored in the data table.
Referring to fig. 7, after the positioning operation is successfully performed corresponding to the play time D, the second sub-cursor 02 is moved to the play time D. The operation of reading the latest playing time from the data table is repeatedly executed, in this embodiment, the playing time F is read, and when it is detected that the playing time F is different from the playing time D, the positioning operation is executed corresponding to the playing time F.
It should be noted that, after the positioning operation performed corresponding to the playing time D fails, the latest playing time is read from the data table, and since the current latest playing time is the playing time F, the exchange of the identifiers corresponding to the two stacks and the subsequent operations thereof are continuously performed, so that the playing time D is skipped, and the positioning operation is directly performed corresponding to the playing time F. If the target playing time is the playing time D, the latest playing time is the playing time D, and at this time, the playing time D is skipped, the playing time C is read, so that the positioning operation is performed corresponding to the playing time C, and after the positioning is successful, the second sub-cursor 02 is moved to the playing time C.
Referring to fig. 8, after the positioning operation is successfully performed corresponding to the playing time F, the positioning operation is finished, and further, it may be determined whether a new adjustment instruction is received, if the new adjustment instruction is not received, all data in the data table is cleared, and the first sub-cursor 01 and the second sub-cursor 02 are merged into an independent cursor and indicate the position at the playing time F. And if a new adjusting instruction is received, responding to the new adjusting instruction to acquire the playing time, moving the first sub-cursor 01 to the playing time, and storing the playing time. Further, the above operation is repeatedly performed. In particular, the embodiments of the present invention will not be described in detail herein.
Of course, in the above case where the user repeatedly presses the key of the remote controller for multiple times, referring to fig. 9, when the user sends the first adjustment instruction, and continuously presses the key of the remote controller, so that the play time corresponding to the initial adjustment instruction is the play time C or the play time H, the user needs to further send an adjustment instruction to adjust the play progress to the play time F. The user still needs to repeatedly send the adjustment instruction for multiple times from the playing time C or the playing time H to the playing time F, and responds to the process that the user repeatedly adjusts the playing time for multiple times, which is similar to the above description, and detailed description is omitted here.
It should be noted that, if the playing time H is the ending playing time of the audio/video, after the playing time H is reached, the user continues to adjust the playing progress to the right, then the playing time H is not stored any more, and the first sub-cursor 01 does not move any more.
Therefore, the progress positioning method for receiving the multiple instructions for adjusting the playing progress within the preset time of the terminal adopting the scheme can be used for executing the positioning operation only corresponding to the current latest playing time next time after the execution of one positioning operation is finished, so that the response time of the whole progress adjusting process can be shortened. In addition, the scheme can respectively indicate the playing time corresponding to the adjustment instruction and the actually positioned playing time through the two cursors, so that the current playing progress and the target progress can be more clearly determined, and the use operation of a user is further improved.
Further, referring to fig. 10, in an optional implementation manner of the present disclosure, fig. 10 is a flowchart of a method for positioning a progress by receiving multiple instructions for adjusting a playing progress within a preset time of a terminal according to an embodiment of the present disclosure, where the embodiment of the present disclosure starts to perform a positioning operation from a received initial adjustment instruction, and focuses on describing an implementation process of a positioning thread from another perspective, where an instruction storage thread is similar to the above implementation manner and performs an operation of receiving and storing a playing time of each adjustment instruction.
The execution method of the positioning thread comprises the following steps:
step S1001 locates the play time of the received initial adjustment instruction.
Step S1002, judging whether the latest stored playing time is the same as the playing time of the previous successfully positioned adjusting instruction; if the difference is not the same, step S1003 is executed, and if the difference is the same, step S1004 is executed.
And step S1003, positioning the latest stored playing time, and repeatedly executing the step S1002 after the positioning is successful.
Step S1004, determining that the progress positioning is finished.
When the data table storing the adjustment instruction is a data table, after the initial positioning is finished, reading the playing time indicated by the latest stored adjustment instruction from the data table, judging whether the latest stored playing time is the same as the playing time of the adjustment instruction which is successfully positioned last time, if the latest stored playing time is different from the playing time which is successfully positioned last time, indicating that a new adjustment instruction is stored in the data table in the previous positioning process, executing the positioning operation corresponding to the playing time indicated by the latest stored adjustment instruction, and after each positioning operation is finished, circularly executing the above processes until the latest stored playing time is the same as the playing time which is successfully positioned last time, and finishing the positioning.
When the data tables storing the playing time are two data tables, according to the operation content of the instruction storage thread, from the beginning of creating the current data table corresponding to the second identifier to the end of the first positioning operation, the smart television system never stores the playing time to the data table, and the playing time generated in the process of executing the positioning operation is stored in the current data table corresponding to the first identifier.
