Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

For the multi-person collaborative editing application scenario, a feasible implementation method is to initiate file display through one office device and perform file synchronization editing on the office device that initiates the file display.

For example, multiple people discuss the project plan in a conference room and edit the description file of the project plan collaboratively. FIG. 1 is a schematic diagram illustrating an application scenario of collaborative editing according to an embodiment of the present application. As shown in FIG. 1 , the notebook computer 100 in the conference room is connected to a large-screen display device 110 . The description file of the project proposal is loaded on the laptop computer 100, and the laptop computer 100 outputs the file view to the large-screen display device 110 to display the project proposal to the participants in the conference room. During the discussion of the participants, the participants synchronously edit the description file of the project scheme on the notebook computer 100 according to the discussion content, and output the synchronously edited editing result to the large-screen display device 110 for presentation; based on the large-screen display device 110 Show content for further discussion.

For another example, multiple people discuss the project plan through an online meeting, and collaboratively edit the description file of the project plan. FIG. 2 is a schematic diagram of a collaborative editing application scenario according to an embodiment of the present application. As shown in FIG. 2 , user terminal devices P21 to P25 are user terminal devices of users A21 to A25, respectively. The cloud conference server Y20 is a server that provides online conference services.

During an online conference, user A21 uses P21 to initiate an online conference on cloud conference server Y20, and users A22, A23, A24 and A25 use their own user terminal devices P22, P23, P24 and P25 to connect to cloud conference server Y20 respectively to participate in the meeting. In the online meeting process, if user A22 initiates the presentation of the description file of the project proposal, P22 loads the description file of the project proposal, P22 outputs the file view to the cloud conference server Y20, and the cloud conference server Y20 shares the file view to P21, P23, P24 and P25. During the discussion between users A21, A22, A23, A24 and A25, user A22 synchronously edits the description file of the project plan on P22 according to the discussion content and outputs the synchronously edited editing result to the cloud conference server Y20; the cloud conference server Y20 shares the editing results to P21, P23, P24, and P25; users A21, A22, A23, A24, and A25 conduct further discussions based on the editing results displayed by P21, P23, P24, and P25, respectively.

In the application scenarios shown in Figure 1 and Figure 2, the synchronous editing of files can only be performed on the office equipment that initiates the file sharing and presentation. Editing participants may need to confirm the file modification suggestions several times before they can understand how to edit, or, editing participants may need to repeatedly edit the file to achieve the correct editing results corresponding to the file modification suggestions. Lengthening editing time and reducing office efficiency.

In view of the above problems, a feasible implementation solution is that the participants who propose file modification suggestions perform synchronous editing, so as to avoid lengthening and time-consuming editing due to inability to understand the file modification suggestions.

For example, in the application scenario shown in FIG. 1, when participant A11 proposes file modification, participant A11 moves to the operating position of laptop computer 100, and participant A11 performs synchronous editing on laptop computer 100; When a file modification suggestion is proposed, the participant A12 moves to the operating position of the notebook computer 100, and the participant A12 performs synchronous editing on the notebook computer 100.

For another example, in the application scenario shown in FIG. 2 , when user A21 proposes file modification, cloud conference server Y20 issues editing authority to P21, and user A21 performs synchronous editing on P21; when user A22 proposes file modification , the cloud conference server Y20 issues the editing authority to P22, and user A22 performs synchronous editing on P22.

Based on the above solution, although the time-consuming editing of synchronous editing is effectively shortened each time, in the multi-person collaborative editing application scenario, since there are multiple users (participants) participating in editing, multiple users may appear at the same time. Multiple file modification suggestions are proposed, or multiple users have successively proposed multiple file modification suggestions in a short period of time. However, if only one user's file modification suggestion can be synchronously edited at a time, the editing speed often cannot catch up with the file modification suggestion. , thereby greatly reducing office efficiency.

In view of the above problems, a feasible solution is to send the content that needs to be collaboratively edited to the personal device of each user in the multi-person collaborative editing application scenario. edit. As shown in Figure 2, in the online conference process, assuming that user A22 initiates the presentation of the description file of the project proposal, then P22 loads the description file of the project proposal, and P22 sends the description file of the project proposal to the cloud conference server Y20, and the cloud conference server Y20 Share the description file of the project plan to P21, P23, P24 and P25. During the discussion, users A21, A22, A23, A24 and A25 perform synchronous editing on their own user terminal devices P21, P22, P23, P24 and P25 respectively. Synchronous edits are merged to produce the final discussion results file.

However, when a user edits according to his own file modification suggestion, even if the user simultaneously dictates his own file modification suggestion, for other users, it is difficult to confirm the corresponding file modification suggestion of the user because the dictation is not intuitive. Edit results. If the subsequent discussion must rely on the modification suggestion of the file, it may still be necessary to wait for the user to complete the synchronous editing and share the editing results before continuing the discussion, which will still cause the user to stop discussing and wait for a user to complete the editing situation. Moreover, when multiple users are editing at the same time, it is difficult to merge multiple editing results after editing is completed, and the editing results still need to be discussed one by one, and the office efficiency is still very low.

In view of the above problems, an embodiment of the present application proposes a multi-person collaborative editing solution. In the multi-person collaborative editing solution of the present application, multiple users participating in the collaborative editing use their own user terminal devices to edit the media objects that need to be collaboratively edited, and the editing operations of each user are shared with the user terminals of other users On the device, each user's user terminal device generates a combined editing result based on the editing operations of the user on its own device and the editing operations of other users, so that any A user can see all user edits to media objects.

Further, in order to realize synchronous sharing of editing operations among different user terminal devices, in an embodiment of the present application, the collaborative editing process is divided into multiple editing cycles, and at the end of each editing cycle, all users in the editing cycle are divided into multiple editing cycles. All editing operations are shared among all user terminal devices participating in collaborative editing; at the end of each editing cycle, the currently displayed editing results are refreshed according to all editing operations of all users, so that all user terminals participating in collaborative editing The synchronization of editing operations based on the editing cycle is implemented on the device.

Taking a specific application scenario as an example, for example, FIG. 3 is a schematic diagram of a collaborative editing application scenario according to an embodiment of the present application. As shown in Figure 3, user terminal devices (P31, P32, P33, P34, and P35 of users A31 to A3n can be connected to shared display device Y31. User A31 will need to collaboratively edit media objects (eg, text and/or pictures) Project the screen from P31 to the public sharing device (shared display device Y31). Users A32 to A3n connect their user terminal devices (P32 to P35) to the shared display device Y31; The display device Y31 coordinates the media objects shared by P31 to P32 to P35 across the terminals, and the shared display device Y31 displays the overall media object. P31 to P35 can collaborate and edit this media object across devices.

Specifically, P31 is connected to the shared display device Y31, and initiates collaborative editing for the media objects that need to be collaboratively edited; after the shared display device Y31 accepts the collaborative editing request initiated by P31, P31 sends the media objects that need to be collaboratively edited to the shared display device Y31 .

P32~P35 are connected to the shared display device Y31, and request to join the collaborative editing; after the shared display device Y31 accepts the request to join the collaborative editing from P32~P35, it shares the media objects that need to be collaboratively edited to P32~P35.

In the editing cycle 511, the users A32 and A33 simultaneously edit the media object 500 on the laptop computer P32 and the mobile phone P33, respectively. When the editing cycle 511 ends, the editing results displayed on the shared display devices Y31 and P31-P35 are the media object 501, which is the fusion of the media object 500 and the editing operations of user A32 and user A33.

In the editing cycle 512, the user A32 continues to edit on the laptop computer P32, and the users A31 and A34 are simultaneously editing on the tablet computer P31 and the mobile phone P34 respectively. At the end of the editing cycle 512, the editing results displayed on the shared display devices Y31, P31-P35 are the media object 502, and the media object 502 is the fusion of the media object 501 and the editing operation of the user A32, the editing operation of the user A31, and the editing operation of the user A34.

In the editing cycle 513, the user A33 simultaneously edits the media object 502 on the mobile phone P33. When the editing cycle 513 ends, the editing results displayed on the shared display devices Y31, P31-P35 are the media object 503, and the media object 503 is the fusion of the editing operation of the media object 502 and the user A33.

FIG. 6 is a schematic diagram illustrating an execution flow of a user terminal device according to an embodiment of the present application. During the collaborative editing process by the users A31-A3n using their own office equipment (P31-P35), each terminal device in the user terminal devices (P31-P35) participating in the collaborative editing executes S500-S540 as shown in Fig. 6 . The following describes the execution processes of S500 to S540 by taking the user terminal device P31 as an example.

S600, P31 records all editing operations performed by user A31 on P31 in the current editing cycle, and aggregates them into a second editing operation record.

Illustratively, in an implementation manner of S600, in order to facilitate the recording and transmission of editing operations, the editing operations are recorded by means of compression encoding for atomic operations.

Specifically, atomic operations are defined according to all possible editing operations for the media object, and atomic operations are basic editing operations. For example, for text input (INSERT), copy (COPY), paste (PASTE), delete (DELETE); another example, for image pixel drawing. Any user editing operation on a media object can be decomposed into a combination of one or more atomic operations. For example, the user modifies "one" in the text "first device" to "two", which can be decomposed to delete "one", and type "two" after "the first"; another example, the user draws a black circle on the picture, It can be decomposed to draw multiple black pixels in a row (eventually forming a circle).

Further, in S600, P31 monitors the editing action of user A31 on P31 in real time, collects the editing content, and converts it into an atomic operation record without a causal sequence. The atomic operation record includes:

Operators: For example, INSERT, DELETE;

Content operator: change information of a single operation;

Position operator: the offset vector of the change information of a single operation in the baseline document;

Auxiliary position operator: Reference operation and reference offset vector when the position operators are the same.

Further, in S600, P31 independently compresses and encodes the newly added atomic operation record in one editing cycle to generate an editing operation record (editing operation code). In the editing operation code, each atomic operation record has no causal sequence. Specifically, the editing operation code includes:

Edit Baseline: The baseline version of the document where the atomic operation occurred;

Edit author: the user account for modifying the document;

Number of operations: the number of atomic operations contained in the encoding package;

Operational data: Atomic operations record data.

S610, P31 outputs the second editing operation record to the shared display device Y31.

S620, P31 receives the first editing operation record sent by the shared display device Y31, the first editing operation record corresponds to all user terminal devices participating in the collaborative editing, and all other user terminal devices other than the user terminal device in the current editing cycle. all editing operations.

S630, P31 merges the editing operations corresponding to the first editing operation record and the second editing operation record to generate a collaborative editing result.

Illustratively, in an implementation manner of S630, in the current editing cycle, P31 synchronously generates the first editing result when user A31 performs an editing operation; when the current editing cycle ends, P31, according to the first editing operation record, The first editing result is edited, and the collaborative editing result of the current editing cycle is generated.

Exemplarily, in another implementation of step 450, when the current editing cycle ends, P31 merges the first editing operation record and the second editing operation record; The object is edited to generate a collaborative editing result of the current editing cycle, wherein the media object corresponding to the current editing cycle is the collaborative editing result of the previous editing cycle.

For example, in an implementation manner of S630, the collaborative editing result adopts a layered echo mode, and the editing operations of each user are integrated to form a new text/new layer; the editing results of all users are presented in layers and completely. operate. That is, the collaborative editing result includes multiple display layers, and each display layer corresponds to an editing operation of a user; or, each display layer corresponds to an editing operation; or, each display layer corresponds to an atomic operation. In this way, editing for user operations, editing operations, or atomic operations can be implemented through operations on the display layer (eg, selecting, deleting, hiding, copying, etc.).

Specifically, in an implementation manner of S630, P31 decodes the editing operation code, and independently restores each atomic operation information according to the decoded data to form a new text/new layer. Each layer contains:

Changed content: the editing result of the atomic operation on the document;

Operators: Identify different operators and different users through different markers (color, strikethrough, etc.);

Change position: Determine the display position of the changed content on the interface based on the position operator and the auxiliary position operator.

Further, after S630, S640 is also included, and P31 refreshes the display of P31 according to the collaborative editing result. In another implementation manner, after S630, P31 can also output the collaborative editing result to other terminal devices/display devices for display.

Further, since the editing operation is merged in a hierarchical echo mode, it is equivalent to recording the editing process in the editing result, and the editing result contains a large number of marks, which may affect the subsequent collaborative editing. Therefore, in an embodiment of the present application, after S640, a step of accepting the baseline is also included: the user A31 confirms and accepts the historical operation process and results on P31, solidifies the current editing state, and forms a new baseline; or, P31 accepts other terminal devices (P32~P35) New baseline sent.

Further, after S640, a saving process is also included, that is, when the collaborative editing ends, the user A31 saves the editing result of the collaborative editing on P31. Specifically, the saving process can be triggered by user A31 on P31, or can be triggered by other users (A32-A35) on other terminal devices (P32-P35). In the saving process, the edited content is merged into the initial version to form a new version file and saved. In one embodiment, the save process supports two forms of save:

Save: delete the operation process record, merge the editing process data, and save only the final editing result.

Operation save: keep operation process records and edit process data.

S704, refresh the display of the shared display device Y31 according to the collaborative editing result; please refer to S640 for specific implementation.

Further, in an actual application scenario, there is a situation where a user terminal device accesses a group for collaborative editing, but the user does not perform an editing operation. In this case, the user terminal device does not perform S400 and S410.

Further, the collaborative editing method proposed in the embodiment of the present application can also be applied to other collaborative editing application scenarios other than the application scenario shown in FIG. 3 .

For example, in a collaborative editing application scenario, the shared display device Y31 is not configured, but a cloud conference server is used instead of the shared display device Y31 to construct online collaborative editing. Referring to the online conference system shown in Figure 2, as shown in Figure 2, in a collaborative editing application scenario, user A21 uses P21 to initiate collaborative editing to cloud conference server Y20; users A22, A23, A24 and A25 use P22, P23 respectively , P24 and P25 to join collaborative editing. P21 loads the media objects that need to be edited together and sends the media objects to the cloud conference server Y20; the cloud conference server Y20 distributes the media objects to P22, P23, P24 and P25 based on the distributed media data management capability; P22, P23, P24 and P25 Load media objects individually.

During the collaborative editing process, the editing operations of users A21, A22, A23, A24 and A25 on P21, P22, P23, P24 and P25 are sent to the cloud conference server Y20; the cloud conference server Y20 forwards the received editing operations to the sending User terminal equipment other than the party; P21, P22, P23, P24 and P25 generate editing results according to the synchronous editing operations of users A21, A22, A23, A24 and A25, and synchronously refresh their own display of media objects according to the editing results .

Specifically, P21 to P25 execute the flow shown in FIG. 6 . The cloud conference server Y20 executes S701 and S702 as shown in FIG. 7 .

For example, in a collaborative editing application scenario, the shared display device Y31 is not configured, but one of the terminal devices participating in the collaborative editing is used to replace the shared display device Y31. Specifically, assuming that the P31 is used as the co-editing host, the P31 performs the following steps:

P31 records all editing operations performed by user A31 on P31 in the current editing cycle, and aggregates them into a second editing operation record;

P31 receives the editing operation records of all editing operations in the current editing cycle from P32 to P35;

P31 forwards the editing operation record of the current editing cycle to other devices other than the sender;

P31 merges all editing operations of P31 to P35 in the current editing cycle to generate the collaborative editing result of the current editing cycle; please refer to S630 for the specific implementation;

P31 refreshes the display of the shared display device Y31 according to the collaborative editing result; please refer to S640 for specific implementation.

The implementation effect of the collaborative editing method of the present application will be described below through specific application examples.

For example, FIG. 8 is a schematic diagram showing an editing effect of collaborative editing of pictures according to an embodiment of the present application. The media object that needs to be edited collaboratively is the picture shown as 800 in FIG. 8 . It is assumed that users A32 and A33 want to perform editing operations on the picture 800 . For example, as shown in FIG. 8 , user A32 wishes to draw a circle on area 801 , and user A33 wishes to draw a cross on area 802 .

According to the collaborative editing solution of the embodiment of the present application, users A32 and A33 can perform respective editing operations synchronously on P32 and P33, respectively. At the end of each editing cycle, P32 sends the editing operation (the process of drawing a circle on the area 801) of user A32 in the editing cycle to the shared display device Y31, and the shared display device Y31 sends the editing operation sent by P32 to P31, P33～P35. At the end of each editing cycle, P33 sends the editing operation of user A33 in the editing cycle (the process of drawing a cross on the area 802) to the shared display device Y31, and the shared display device Y31 sends the editing operation sent by P33 to P31, P32, P34～P35.

At the end of each editing cycle, P31 to P35 and the shared display device Y31 generate editing results and refresh the display according to the editing operation of the user A32 and the editing operation of the user A33. Finally, the same collaborative editing results are displayed on P31 to P35 and the shared display device Y31. For example, assuming that P33 is a mobile phone, P33 displays the interface shown in 803 in FIG. 8 .

For another example, FIG. 9 is a schematic diagram illustrating an editing effect of collaborative text editing according to an embodiment of the present application. The media object that needs to be collaboratively edited is the text shown as 900 in FIG. 9 . It is assumed that users A32 and A33 want to perform editing operations on the text 900 . For example, as shown in Fig. 9, user A32 wishes to delete "also known as the Internet" in text 900; user A33 wishes to change "Internet (Internet), Internet" in text 900 to "Internet or Internet" .

According to the collaborative editing solution of the embodiment of the present application, users A32 and A33 can perform respective editing operations synchronously on P32 and P33, respectively. At the end of each editing cycle, P32 sends the editing operation of user A32 in the editing cycle (deleting "also known as the Internet") to the shared display device Y31, and the shared display device Y31 sends the editing operation sent by P32 to P31, P33～P35. At the end of each editing cycle, P33 sends the editing operation of user A33 in the editing cycle (change "Internet (Internet), Internet" to "Internet or Internet") to the shared display device Y31, and share the The display device Y31 sends the editing operation sent by P33 to P31, P32, and P34 to P35.

At the end of each editing cycle, P31 to P35 and the shared display device Y31 generate editing results and refresh the display according to the editing operation of the user A32 and the editing operation of the user A33. The final display results on P31 to P35 and the shared display device Y31 are shown as text 903 in FIG. 9 .

In the collaborative editing solution of the embodiment of the present application, since the sharing and synchronization of editing operations are performed at the end of each editing cycle, the editing results displayed on different user terminal devices are in line with the editing operations of all users. The processes are also synchronized, which greatly improves the user experience of collaborative editing.

Further, in an actual application scenario, since each user terminal device participating in collaborative editing performs sharing and synchronization of editing operations at the end of the editing period, the editing operations may be continuously performed during the editing period. Therefore, during the editing cycle, there may be situations in which the editing operation process and the editing result of the media object are not synchronized between different user terminal devices. The shorter the editing period is set, the better the synchronization between the editing results displayed on the user terminal device and the user editing operations on other user terminal devices.

Further, in an actual application scenario, since multiple users edit media objects at the same time, the editing result displayed by the user terminal device includes editing traces of multiple different users. In this implementation manner, when P31 sends the editing operation record to the shared display device Y31, the editing operation is bound to the user identification (eg, user account) of A31. In S620, the editing operation records sent by the shared display device Y31 are all bound with the user IDs who performed the editing operation. In S630, P31 marks the editing operations included in the collaborative editing result according to the difference of the user IDs bound to the editing operation records (for example, using different colors to mark the editing operations of different users; for example, adding additional editing operations to the editing operation) Annotation, mark the user ID in the annotation).

For example, in the embodiment shown in FIG. 8, user A32 draws a circle on area 801 and user A33 draws a cross on area 802 using the default color (black). According to the collaborative editing solution of this embodiment of the present application, in the final display 803 on P31 to P35 and the shared display device Y31, the circle drawn by user A32 is displayed in red, and the cross drawn by user A33 is displayed in blue.

Further, in an actual application scenario, since multiple users edit media objects at the same time, it may happen that multiple users edit the same part of the media objects at the same time. For example, FIG. For example, a schematic diagram of the editing effect of collaborative editing of pictures. As shown in FIG. 10 , the user A32 wishes to draw a circle on the area 1001 , and at the same time, the user A33 wishes to draw a cross on the area 1001 . In this case, the editing operations of user A32 and user A33 will conflict, and the merged editing results are likely to be displayed in confusion.

In the case of conflicting editing operations, in an embodiment of the present application, after a user participating in collaborative editing starts editing a part of a media object, the editing operation is shared with user terminal devices of other users participating in collaborative editing. When a user terminal device receives an editing operation shared by other user terminal devices, it not only combines the editing operations to generate an editing result, but also locks the editing area corresponding to the editing operation, and the user cannot edit the locked editing area. edit. When there is no editing operation for the locked editing area, the locked state is released, and then the user can edit the editing area based on the completed editing result.

For example, FIG. 11 is a schematic diagram showing an editing effect of collaborative editing of pictures according to an embodiment of the present application. As shown in FIG. 11 , when user A32 starts to draw a circle on area 1101, user A33 cannot draw a cross on area 1101, and can only wait for the user to start drawing a circle on area 1101. Edit on the basis. For example, assuming that P33 is a mobile phone, user A33 edits area 1102 in the interface shown in FIG. 1103 .

For the case of conflicting editing operations, in another embodiment of the present application, multiple users perform editing operations at the same time and share the editing operations with each other. Conflicting editing operations are merged separately to obtain multiple editing results. The user terminal device displays the multiple editing results to the user respectively (eg, split-screen display), so that the users can discuss with each other to confirm the finally adopted editing result.

For example, FIG. 12 is a schematic diagram showing an editing effect of collaborative editing of pictures according to an embodiment of the present application. As shown in FIG. 12 , user A32 draws a circle on area 1201 , while user A33 draws a cross on area 1201 . Finally, the same collaborative editing results are displayed on P31 to P35 and the shared display device Y31. For example, assuming that P33 is a mobile phone, P33 displays a display interface as shown in picture 1202 in FIG. 12 .

It can be understood that, some or all of the steps or operations in the foregoing embodiments are only examples, and other operations or variations of various operations may also be performed in the embodiments of the present application. Furthermore, the various steps may be performed in a different order presented in the above-described embodiments, and may not perform all operations in the above-described embodiments.

Further, in the 1990s, an improvement in a technology can be clearly differentiated between improvements in hardware (for example, improvements to circuit structures such as diodes, transistors, switches, etc.) or improvements in software (improvements in method procedures). ). However, with the development of technology, the improvement of many methods and processes today can be regarded as a direct improvement of the hardware circuit structure. Designers almost get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by hardware entity modules. For example, a programmable logic device (P2rogrA2mmA2ble Logic Device, P2LD) (such as a field programmable gate array (Field P2rogrA2mmA2ble GA2te A2rrA2Y2, FP2GA2)) is such an integrated circuit whose logical function is determined by the access party programming the device. It is programmed by the designer to "integrate" a digital device on a piece of P2LD, without the need for a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of making integrated circuit chips by hand, this kind of programming is also mostly implemented using "logic comP2iler" software, which is similar to the software compiler used in program development and writing, and needs to be compiled before compiling. The original code also has to be written in a specific programming language, which is called hardware description language (HA2rdwA2re DescriP2tion LA2nguA2ge, HDL), and there is not only one HDL, but many kinds, such as A2BEL (A2dvA2nced BooleA2n ExP2ression LA2nguA2ge) 、A2HDL(A2lterA2 HA2rdwA2re DescriP2tion LA2nguA2ge)、Confluence、CUP2L(Cornell UniversitY2 P2rogrA2mming LA2nguA2ge)、HDCA2l、JHDL(JA2vA2 HA2rdwA2re DescriP2tion LA2nguA2ge)、LA2vA2、LolA2、MY2HDL、P2A2LA2SM、RHDL(RubY2 HA2rdwA2re DescriP2tion LA2nguA2ge)等，目前最普遍使用The ones are VHDL (VerY2-High-SP2eed IntegrA2ted Circuit HA2rdwA2re DescriP2tion LA2nguA2ge) and Verilog. It should also be clear to those skilled in the art that a hardware circuit for implementing the logic method process can be easily obtained by simply programming the method process in the above-mentioned several hardware description languages and programming it into the integrated circuit.

The controller may be implemented in any suitable manner, for example, the controller may take the form of eg a microprocessor or processor and a computer readable medium storing computer readable program code (eg software or firmware) executable by the (micro)processor , logic gates, switches, application specific integrated circuits (A2P2P2licA2tion SP2ecific IntegrA2ted Circuit, A2SIC), programmable logic controllers and embedded microcontrollers, examples of controllers include but are not limited to the following microcontrollers: A2RC 625D, A2tmel A2T91SA2M, MicrochiP2 P2IC18F26K20 and Silicon LA2bs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer-readable program code, the controller can be implemented as logic gates, switches, application-specific integrated circuits, programmable logic controllers and embedded devices by logically programming the method steps. The same function can be realized in the form of a microcontroller, etc. Therefore, such a controller can be regarded as a hardware component, and the devices included therein for realizing various functions can also be regarded as a structure within the hardware component. Or even, the means for implementing various functions can be regarded as both a software module implementing a method and a structure within a hardware component.

In addition, all or part of these modules can be integrated together, and can also be implemented independently.
