The downlink synchronization refers to metadata transmission from the HDC side to the electronic device side and data or resource information transmission from the HDC side to the electronic device side.

For example, the electronic device 1 (e.g. a mobile phone) may synchronize the photos to the HDC through uplink synchronization, the electronic device 2 (e.g. a tablet) may obtain the photos of the electronic device synchronized to the HDC from the HDC through downlink synchronization, and similarly, the electronic device 1 may also obtain the photos of the electronic device 2 synchronized to the HDC. Thus, by bidirectional synchronization, the electronic device 1 and the electronic device 2 can view the same photo content.

4) An application package (application package, APK), an application package file format used by the operating system for distributing and installing mobile applications and middleware. For the code of an application to run on an electronic device, it must be compiled and then packaged into a file that can be recognized and executed by the operating system, and the file format that can be recognized and executed by the operating system is APK.

5) A software development kit (software development kit, SDK) is a collection of development tools for creating application software for a particular software package, software framework, hardware platform, operating system, etc. Typical SDKs include utilities for debugging and other purposes, may simply provide some files of an application programming interface for a programming language, and may also provide complex hardware capable of communicating with an embedded system of some kind. SDKs also often include example code, supporting technical notes, or other supporting documents that clarify the suspects for the underlying reference material. The collection of related documents, examples, and tools that assist in developing a certain class of application software may be referred to as an SDK.

It should be understood that in embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one (item) below" or the like, refers to any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b or c may represent: a, b, c, a and b, a and c, b and c, or a, b and c, wherein a, b and c can be single or multiple.

Currently, electronic devices may utilize external storage devices such as cloud storage devices, HDC devices, etc. for storage or backup of data content (e.g., media content). However, the electronic device needs to download the APP matched with the external storage device to access and manage the content in the external storage device, which is different from the manner in which the electronic device directly accesses the locally stored data content. Therefore, the current electronic device cannot simply and efficiently access the content local to the electronic device and the content in the external storage device at the same time.

FIG. 1 is a schematic diagram of a method for an electronic device to access and manage content in an HDC device. As shown in fig. 1, taking an electronic device as a mobile phone and an external storage device as an HDC device as an example, the HDC device is a mass storage device deployed in a home network, has the capability of multi-device content backup and synchronization, and can realize functions of long-time reliable storage of data content, convenient personal access and management at any time and any place, and the like. The mobile phone can be provided with a home storage APP (matched with the HDC) and interact with the HDC equipment through the home storage APP, so that the media content on the mobile phone is sent to the HDC equipment for storage or backup, and the content in the HDC equipment is browsed and managed. Wherein, only home storage APP can access the content in the HDC device, while other APPs such as cameras, gallery or third party applications cannot directly access the content in the HDC device. Therefore, if the user needs to view and share the content in the HDC device through other applications in the mobile phone, the user needs to find the corresponding content from the HDC device through the home storage APP and manually download the content to the media library in the local media frame, and then acquire the corresponding content from the local media library through other applications. Based on the method, a user needs to use two APP to view the content in the HDC equipment, the operation process is complex and complicated, and the use efficiency and the user use experience are low. In addition, the user can directly access the content stored locally on the electronic device through other applications in the handset. Therefore, for the content in the HDC device and the content local to the electronic device, the electronic device needs to access in two different modes, so that the effect of fusion access to the content in the local and the HDC device cannot be achieved, the operation process of the electronic device for accessing the content is more complicated and complicated, and the efficiency of the electronic device for accessing and managing different contents and the user experience are also reduced.

In view of the above problems, embodiments of the present application provide a content management method, an electronic device, and a system, which are used for improving efficiency of accessing multi-terminal stored content by the electronic device and improving user experience.

The modem processor may include a modulator and a demodulator. The modulator is used for modulating the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal.

The application processor outputs sound signals through an audio device (not limited to speaker 270A, receiver 270B, etc.), or displays images or video through display screen 294. In some embodiments, the modem processor may be a stand-alone device.

The SIM card may be inserted into the SIM card interface 295 or removed from the SIM card interface 295 to enable contact and separation from the electronic device 200.

It should be appreciated that in practical applications, the electronic device 200 may include more or fewer components than shown in fig. 2, and embodiments of the present application are not particularly limited. The illustrated electronic device 200 is only one example, and the electronic device 200 may have more or fewer components than shown in the figures, may combine two or more components, or may have a different configuration of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

The software system of the electronic device 200 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the application, taking an Android system with a layered architecture as an example, a software structure of an electronic device is illustrated.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. As shown in fig. 3, the software architecture can be divided into four layers, from top to bottom, an application layer, an application framework layer (FWK), an Zhuoyun row and system libraries, and a Linux kernel layer.

The application layer is the top layer of the operating system, including native applications of the operating system, such as cameras, gallery, calendar, bluetooth, music, video, information, and so forth. An application program referred to in the embodiments of the present application is simply referred to as Application (APP), which is a software program capable of implementing one or more specific functions. Typically, a plurality of applications may be installed in an electronic device. Such as camera applications, mailbox applications, smart home control applications, and the like. The application mentioned below may be a system application installed when the electronic device leaves the factory, or may be a third party application downloaded from a network or acquired from other electronic devices by a user during the process of using the electronic device.

Of course, for a developer, the developer may write an application and install it to that layer. In one possible implementation, the application may be developed using Java language, by calling an application programming interface (Application Programming Interface, API) provided by the application framework layer, through which a developer may interact with the underlying layers of the operating system (e.g., kernel layer, etc.) to develop his own application.

The application framework layer provides APIs and programming frameworks for application programs of the application layer. The application framework layer may include some predefined functions. The application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include information such as files (e.g., documents, video, images, audio), text, etc.

The view system includes visual controls, such as controls that display text, pictures, documents, and the like. The view system may be used to build applications. The interface in the display window may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is for providing communication functions of the electronic device. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction.

The android runtime includes a core library and virtual machines. And the android running time is responsible for scheduling and managing an android system.

The core library of the android system comprises two parts: one part is a function which needs to be called by Java language, and the other part is a core library of the android system. The application layer and the application framework layer run in a virtual machine. Taking Java as an example, the virtual machine executes Java files of the application layer and the application framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: a surface manager, a media library, a three-dimensional graphics processing library (e.g., openGL ES), a two-dimensional graphics engine (e.g., SGL), an image processing library, and the like. The surface manager is used to manage the display subsystem and provides a fusion of two-dimensional and three-dimensional layers for multiple applications. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.564, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. A two-dimensional graphics engine is a drawing engine that draws two-dimensional drawings.

The kernel (kernel) layer provides core system services of the operating system, such as security, memory management, process management, network protocol stacks, driving models, and the like, which are implemented based on the kernel layer. The kernel layer also acts as an abstraction layer between the hardware and software stacks. This layer has many drivers associated with the electronic device, the main drivers being: a display drive; a keyboard driver as an input device; flash driving based on memory technology equipment; a camera drive; an audio drive; bluetooth driving; wiFi drive, etc.

It should be understood that the functional services described above are only examples, and in practical applications, the electronic device may be divided into more or fewer functional services according to other factors, or the functions of the respective services may be divided in other manners, or the functional services may not be divided, but may operate as a whole.

The following describes in detail the solutions provided in the present application with reference to specific embodiments.

The scheme provided by the embodiment of the application can be applied to a system formed by at least one electronic device and an external storage device, wherein the external storage device is used for providing services such as storage, backup and synchronization of contents for the at least one electronic device. The external storage device may be, for example, an HDC device, a cloud server, or the like. In one aspect, each electronic device may up-synchronize its own content to the external storage device, so as to store or back up its own content to the external storage device. On the other hand, the external storage device may synchronize the stored content downstream to the respective electronic devices, so that each electronic device may view and manage the content in the external storage device (including the content of the electronic device itself and the content of some other electronic devices stored in the external storage device), and so on. The content in the external storage device or the electronic device may be various data, resources, information, etc., and may be media content such as images, videos, audios, files, etc.

It should be noted that, in the embodiments of the present application, the synchronization of the content of the external storage device to the electronic device specifically refers to transmitting metadata of the content stored in the external storage device to the electronic device for storage, where based on the metadata, the electronic device may acquire corresponding content from the external storage device at any time; in this embodiment of the present application, synchronizing the content of the electronic device to the external storage device refers to transmitting the content stored in the electronic device and metadata thereof to the external storage device for storage. Wherein the metadata is data for describing contents in the electronic device or the external storage device, and the contents described by the metadata can be acquired based on the metadata.

In the embodiment of the application, the external storage device and the at least one electronic device can communicate based on a wired or wireless communication mode. Alternatively, the external storage device and the electronic device may access the same lan, or may access different lans.

For example, the external storage device and the electronic device establish a wireless connection with the same wireless access point. The external storage device and the electronic device may also access the same wireless fidelity (wireless fidelity, wi-Fi) hotspot. For another example, the external storage device and the electronic device may also access the same bluetooth beacon via the bluetooth protocol. For another example, the external storage device and the electronic device may trigger a communication connection through a near field communication (near field communication, NFC) tag, and transmit encrypted information through the bluetooth module to perform identity authentication. After authentication is successful, data transmission is performed by a point-to-point (P2P) mode.

The scheme provided in the embodiment of the application is described below by taking electronic equipment as terminal equipment and external storage equipment as HDC equipment as an example.

Fig. 4 is a schematic diagram of an architecture of a possible system to which the solution provided in the embodiment of the present application is applicable. As shown in fig. 4, the system includes at least: HDC devices and terminal devices (e.g., cell phones). A system application (such as the gallery shown in fig. 4) and a third party application may be installed in the terminal device. The terminal equipment also comprises an HDC service, a media library and a file system.

The HDC service is used for realizing uplink and downlink synchronization of the content between the terminal equipment and the HDC equipment. The file system may be used to store the content of the terminal device itself, as well as the content synchronized by the terminal device from the HDC device. The media library can be used for managing the content stored by the terminal equipment, such as data and files of system applications and third party applications in the terminal equipment; and on the other hand can be used to manage the content synchronized by the terminal device from the HDC device. In addition, the media library may provide an HDC synchronization interface to the HDC services, as well as an access interface to system applications and third party applications. The HDC service can interact with the media library by calling the HDC synchronization interface, thereby completing the uplink and downlink synchronization of the content. The system application and the third party application can access the content managed by the media library through the access interface, so that the system application and the third party application can realize the fusion access and management of the local content of the terminal equipment and the content synchronized from the HDC equipment, and further the access efficiency and the user experience are improved. Optionally, a home storage APP may also be installed in the terminal device, where the home storage APP may also be used to access and manage the HDC device and its stored content.

Alternatively, in the system shown in fig. 4, both the HDC device and the terminal device may be implemented by the hardware architecture shown in fig. 2 and the software architecture shown in fig. 3.

Further, as shown in fig. 5, the HDC service of the terminal device in the system shown in fig. 4 may include two sub-services, which are an application side synchronization service and an end side synchronization service, respectively. Among other things, the application-side synchronization service may be deployed in the form of a software development kit (software development kit, SDK) in a home storage APP or set system application (e.g., the gallery application shown in fig. 5). The end-side synchronization service may be deployed in the form of an application installation package (application package, APK) in the software hierarchy of the terminal device.

The application side synchronization service is mainly used for providing the following functions:

1) Synchronization status notification

The application side synchronization service can acquire the information of the progress and the state of the uplink and downlink synchronization between the terminal equipment and the HDC equipment from the end side synchronization service, and can inform the information to the user so that the user can timely acquire the information of the progress and the state of the synchronization between the terminal equipment and the HDC equipment.

2) Providing content download APIs and download progress notification

The application side synchronization service may acquire a download API of the content (including the content stored in the HDC device and the content locally stored in the terminal device) from the end side synchronization service or the media library, so that an application where the application side synchronization service is located may download the corresponding content from the HDC device by driving the end side synchronization service through calling the download API. In addition, the application side synchronization service may receive a download progress callback notification from the end side synchronization service, where the download progress callback notification is used to instruct the progress of synchronization between the end side synchronization service and the HDC device, and the application side synchronization service may notify the user of the progress through a corresponding notification message.

3) Providing a synchronization control portal

The application side synchronization service may provide a control switch for the user to control the synchronization flow between the terminal device and the HDC device, and provide the control switch to the user, so that the user may control the synchronization flow between the terminal device and the HDC device by operating the control switch.

For example, an application-side synchronization service in a gallery application may provide a gallery synchronization switch to a user that controls the flow of synchronization of images and video between a terminal device and an HDC device. When a user turns on the gallery synchronization switch, the terminal equipment can perform uplink and downlink synchronization between the terminal equipment and the HDC equipment aiming at images and videos, so that consistency of the images and video contents in the terminal equipment and the HDC equipment is ensured. When the user turns off the gallery synchronization switch, the terminal device may stop performing uplink and downlink synchronization of the image and video content with the HDC device.

The end side synchronization service is mainly used for providing the following functions:

1) Synchronization function

The terminal side synchronization service can complete the uplink and downlink synchronization of the content between the terminal equipment and the HDC equipment. For example, the end side synchronization service may include a media library SDK, and the SDK may invoke an ethernet (E) interface to interact with the media library, so that content acquired by the end side synchronization service from the HDC device is sent to the media library, and stored by the media library, to implement downlink synchronization. The SDK may also provide a southbound interface definition language (android interface definition language, AIDL) interface to interact with the media library with which content may be retrieved from the media library, which may be sent by the end-side synchronization service to the HDC device for storage. When uplink and downlink synchronization is performed between the terminal device and the HDC device, metadata may be transmitted in an objectified data format, that is, metadata to be transmitted is objectified by the terminal device or the HDC device and then transmitted to the opposite device.

2) Communication function

The end side synchronization service can complete the interactive processes of discovery, connection establishment, communication, data transmission and the like between the terminal equipment and the HDC equipment. The terminal side synchronization service may include a communication SDK, for example, an SDK that merges a hilnk and a P2P function, where the SDK may establish a data transmission channel with the HDC device based on the hilnk and the P2P communication manner to implement data transmission in the uplink and downlink synchronization process, and may parse the transmitted data and assemble VO data of the media library SDK, and invoke an interface provided by the media library SDK to update the VO data to the media library.

3) Control function

The end side synchronization service can control the up-down synchronization flow between the terminal device and the HDC device. For example, the end-side synchronization service may include a control SDK, where the SDK may receive a data change message from the HDC device (for notifying a change condition of data in the HDC device), and further start an uplink and downlink synchronization procedure according to the received data change message.

In some embodiments of the present application, as shown in fig. 5, the file system of the terminal device may include a local file system and an HDC file system. The local file system is used for storing the content of the terminal equipment, and the HDC file system is used for storing the content synchronized by the terminal equipment from the HDC equipment. The HDC file system may be implemented in the form of a user space file system (filesystem in userspace, FUSE) or in the form of a distributed file system. The local file system and the HDC file system may interface with a virtual file system (virtual file systems, VFS) to interact with the media library and the HDC synchronization service.

In some embodiments of the present application, as shown in fig. 5, the HDC device may include a hypertext transfer protocol (hyper text transfer protocol, HTTP) server, an HDC synchronization service, a media management service, and a file system. The HTTP server can complete interaction with the HDC synchronous service of the terminal equipment through the signaling gateway, and can also complete interaction with the file system through the data gateway, so that data can be read and written from the file system. The HDC synchronization service of the HDC device may perform functions related to up-down synchronization between the HDC device and the terminal device, and management functions for the HTTP server and the media management service. The media management service is used to manage content stored in the file system. The file system is used to store content.

Still further, when the terminal device employs the software system shown in fig. 3 described above, a media library, an HDC service, a file system, etc. in the terminal device may be deployed in the application framework layer shown in fig. 3. Of course, these service structures may be deployed in other software layers according to actual needs, which is not limited in the embodiments of the present application.

The unified media operation framework module can provide a unified interface, package content objects and the like, can shield database operation, and is simple and flexible in the use process. For Android applications, content (including content of local, cloud and DHC ends) of the access terminal device with zero adaptation through an Android native interface is supported. For hong applications, the content (including the content of local and distributed file systems) of the terminal device is supported for access through a unified interface provided by the same.

Specifically, the unified media operation framework module may provide a unified northbound interface to the application layer for APP calls to implement specific content (e.g., media data) management functions.

The unified media service module can provide event management capability related to local, cloud, distributed file systems and HDC equipment, can receive various event information and trigger corresponding business logic operation. The system can also provide transmission and management capability of media resources for local and distributed file systems, cloud ends and HDC equipment, and support the realization of state management of the media resources based on the connection states of the terminal equipment and the cloud ends and the HDC equipment, so that the management and access of media services and the fusion of the media resources on the local and distributed file systems, the cloud ends and the HDC equipment are realized. The module can interact with a distributed soft bus, a cloud space SDK and an application side synchronization service to realize cross-device synchronization of media metadata among a distributed file system, a cloud space and an HDC device and real-time detection and fusion access of media data states. The functions provided by the module can include device discovery, device status (including distributed devices, cloud devices, HDC devices, etc.) monitoring, media data status monitoring, media metadata synchronous transmission, media resource operation, media content transmission caching, etc.

It should be noted that, the system architecture of the device described in fig. 4 to 6 is only an exemplary illustration of the system architecture applicable to the terminal device provided in the embodiment of the present application, and is not limited to the system architecture of the terminal device in the embodiment of the present application, and in practical application, the system architecture adopted by the terminal device is not limited to this.

The scheme provided by the embodiment of the application is mainly divided into two parts, namely content synchronization and content access. The content synchronization part mainly comprises a method for synchronizing the content between the terminal equipment and the HDC equipment, and the content stored in the HDC equipment can be ensured to be known by the terminal equipment side based on the method, and meanwhile, the content of the terminal equipment side can be stored in the HDC equipment; the content access part mainly comprises a method for accessing the content stored in the HDC equipment by a system application or a third party application in the terminal equipment, and based on the method, the system application or the third party application in the terminal equipment can simply, conveniently and quickly obtain the content stored in the HDC equipment without the help of home storage APP and manual intervention, so that the access efficiency and the user experience are improved. The following will specifically describe each.

1. Content synchronization

Referring to fig. 7, the modules or components involved in the content synchronization section mainly include a terminal side synchronization service among the media library of the terminal device and the HDC service, and the HDC device. The media library and the end side synchronization service can communicate through an E interface. The end side synchronization service may communicate with the HDC device based on the P2P approach. The terminal side synchronization service may perform content synchronization with the HDC device by using the communication SDK, and may update the content synchronized with the HDC device into the media library through the E interface by using the media library SDK, so that the media library may perform corresponding processing such as adding, retrieving, updating, deleting (create, retrieve, update, delete, CRUD) operations.

The content synchronization process between the terminal device and the HDC device may be classified into an uplink synchronization process and a downlink synchronization process. The uplink synchronization process refers to the synchronization of the content of the terminal device to the HDC device, and the downlink synchronization process refers to the synchronization of the content of the HDC device to the terminal device.

Referring to fig. 8, taking content synchronized by a terminal device and an HDC device as album content as an example, the method of the downlink synchronization process may include:

s801: the terminal side synchronization service sends a version acquisition request to a media library of the terminal device, wherein the request is used for requesting to acquire media library version information, and the information is used for indicating a historical version of album content in the HDC device.

The terminal side synchronization service may periodically trigger to execute the step S801 and the subsequent steps, so as to periodically determine whether to execute downlink synchronization, and execute the corresponding downlink synchronization process when determining that downlink synchronization needs to be executed.

The media library version information is used to indicate the version of album content in the HDC device after the previous execution of the synchronization process. The HDC device may indicate, to the terminal device, version information of the content in the downlink synchronization in the previous downlink synchronization process, where the media of the terminal device stores the version information as media library version information. When the downstream synchronization is performed, the media library may determine historical version information of the HDC device according to the media library version information, so as to determine whether content in the HDC device is updated based on the historical version information and the latest version information of the HDC device.

S802: the media library sends media library version information to the end side synchronization service.

S803: the end side synchronization service determines whether the version of the album content in the media library is empty according to the version information of the media library, if yes, step S804 is executed, otherwise step S815 is executed.

If the version of the album content in the media library is empty, which indicates that the album content of the HDC device has not been synchronized to the terminal device before or the album content synchronized by the terminal device from the HDC device before has been emptied, the end-side synchronization service may determine that the downlink synchronization mode is full synchronization, and may perform downlink synchronization in the full synchronization mode, that is, synchronize all the album content in the HDC device to the media library of the terminal device.

If the version of the album content in the media library is not empty, the end side synchronization service further determines whether the album content in the HDC device is updated relative to the album content in the media library, if so, determines to perform downlink synchronization in an incremental synchronization mode, namely, synchronize the updated content of the HDC device relative to the media library, thereby ensuring that the content in the media library is updated along with the update of the content in the HDC device; otherwise, it is determined that downlink synchronization is not performed, and execution of the current flow may be stopped.

When determining whether the album content in the HDC device is updated relative to the album content in the media library, the terminal side synchronization service can acquire version information of the album content in the HDC device from the HDC device and compare the version information with the version information of the media library, if the version information is inconsistent with the version information, the album content in the HDC device is determined to be updated, otherwise, the album content in the HDC device and the album content in the media library are determined to be not updated. For specific execution, reference is made to step S815 and subsequent steps below.

In some embodiments of the present application, the content stored in the HDC device may be divided into different types of content according to characteristics such as a data type, a data level, a data source, and a data amount, and after the division, the different types of content may be respectively transmitted, so in a downlink synchronization process, the terminal device and the HDC device may respectively synchronize the different types of content, and in the synchronization process, the different types of content may be transmitted through different interfaces.

For example, in the downlink synchronization process of the album content by the terminal device and the HDC device, the terminal device and the HDC device may divide the album content into an album and media files (pictures and videos) in the album according to a level, and metadata corresponding to the album content is divided into album metadata and file metadata, where the album metadata is used for indicating attribute information of the album, for example, information of identification information of the album, number of images or videos contained in the album, storage location of the album, and the like, and the file metadata is used for indicating information of images or videos in the album, for example, information of identification information of images or videos, storage location, file size, and the like. In the downlink synchronization process, the terminal device and the HDC device can independently transmit album metadata and file metadata.

Furthermore, considering the data volume of the synchronized content, the terminal device and the HDC device can complete full-volume synchronization in a breakpoint continuous transmission mode. Specifically, the terminal side synchronization service of the terminal device may set a synchronization progress identifier to record the progress of the synchronization process, where the synchronization progress identifier may include two factors: a progress identification (unique ID) and a time identification (time ID), wherein the progress identification is used for recording an offset of the synchronous content, and based on the offset, it can be determined which content has completed the synchronization and which content is the content to be synchronized; the time identification is used for recording time information for performing synchronization. In the breakpoint continuous transmission process, the terminal side synchronization service of the terminal equipment updates and stores the corresponding synchronization progress identification locally after acquiring the content from the HDC equipment to the media library for storage each time. If interruption occurs in the synchronization process, when the synchronization process is started again, the end side synchronization service can determine the synchronization progress based on the saved synchronization progress identification, and continuously acquire the content to be synchronized from the HDC device according to the progress to store the content in the media library. After full synchronization is completed, the end-side synchronization service may set a synchronization progress flag to mark that full synchronization has been completed.

When the version of the album content in the media library is empty, the corresponding processing method may refer to the following steps S804 to S814, and when the version of the album content in the media library is not empty, the corresponding processing method may refer to the following steps S815 to S827. The downlink synchronization process using the full-scale synchronization method may refer to the following steps S805 to S814, and the downlink synchronization process using the incremental synchronization method may refer to the following steps S818 to S827.

S804: and the end side synchronization service determines to perform downlink synchronization in a full synchronization mode. And performs the following steps S805 to S814.

S805: the terminal side synchronization service sends a full album acquisition request to the HDC equipment, wherein the request is used for requesting to acquire album metadata corresponding to album contents in the HDC equipment.

S806: and the HDC equipment sends album metadata corresponding to the album content in the HDC equipment to the terminal side synchronous service.

S807: the end side synchronization service sends album metadata to the media library.

S808: the media library stores the received album metadata.

S809: and the media library sends progress indication information to the end-side synchronization service, wherein the progress indication information is used for indicating that the downlink synchronization of the metadata of the album is successfully completed.

After receiving the progress indication information, the end-side synchronization service determines and records the synchronization progress of the metadata of the album according to the progress indication information, so as to update and save the synchronization progress of the metadata of the album.

S810: the terminal side synchronization service sends a full album file acquisition request to the HDC equipment, wherein the request is used for requesting to acquire file metadata corresponding to album contents in the HDC equipment.

S811: and the HDC equipment sends partial file metadata to be synchronized corresponding to the album content in the HDC equipment to the end side synchronization service.

S812: the end side synchronization service sends the partial file metadata to be synchronized to the media library.

S813: the media library stores the received partial file metadata.

S814: and the media library sends progress indication information to the end-side synchronization service, wherein the progress indication information is used for indicating that the downlink synchronization of the partial file metadata is successfully completed.

After receiving the progress indication information, the end-side synchronization service determines and records the synchronization progress of the file metadata according to the progress indication information, so that the synchronization progress of the album metadata is updated and stored.

The steps S810 to S814 may be performed in a loop until all the metadata of the files corresponding to the album content in the HDC device are transmitted and stored in the terminal device successfully, so as to achieve the effect of performing downlink full synchronization by using the breakpoint continuous transmission method.

S815: the end-side synchronization service obtains HDC version information from the HDC device, the information being used to indicate the version of album content in the HDC device.

This version is the latest version of album content in the HDC device.

S816: the end-side synchronization service determines whether the HDC version information and the media library version information are inconsistent, if so, performs step S817, otherwise, performs step S828.

S817: the end side synchronization service determines to perform downlink synchronization in an incremental synchronization mode. And steps S818 to S827 are performed.

Taking an example of a case where there is an increased part of the album content of the HDC device compared with the album content of the terminal device, the end side synchronization service may acquire metadata corresponding to the increased part of the album content from the HDC device and store it, referring to the following steps S818 to S827. For the case of modifying album content in the HDC device, the HDC device may send metadata corresponding to the modified album content to the end-side synchronization service, where the end-side synchronization service may perform corresponding modification. For the case of deleting album content in the HDC device, the HDC device may indicate metadata corresponding to the deleted album content to the end-side synchronization service, so that the end-side synchronization service determines metadata corresponding to the content deleted in the HDC device, and further deletes the stored metadata.

S818: and the end side synchronization service sends an incremental album acquisition request to the HDC equipment, wherein the request is used for requesting to acquire album metadata corresponding to the incremental album content in the HDC equipment.

S819: and the HDC equipment transmits album metadata corresponding to the incremental album content in the HDC equipment to the end side synchronous service.

S820: the end side synchronization service sends the album metadata to the media library.

S821: the media library stores the received album metadata.

S822: and the media library sends progress indication information to the end-side synchronization service, wherein the progress indication information is used for indicating that the downlink synchronization of album metadata corresponding to the incremental album content is successfully completed.

S823: and the end side synchronization service sends an incremental album file acquisition request to the HDC equipment, wherein the request is used for requesting to acquire file metadata corresponding to the incremental album content in the HDC equipment.

S824: and the HDC equipment sends partial file metadata to be synchronized corresponding to the content of the increment album in the HDC equipment to the end side synchronization service.

S825: the end side synchronization service sends the partial file metadata to be synchronized to the media library.

S826: the media library stores the received partial file metadata.

S827: and the media library sends progress indication information to the end-side synchronization service, wherein the progress indication information is used for indicating that the downlink synchronization of the partial file metadata is successfully completed.

The incremental synchronization process may also use the breakpoint continuous transmission method. When the breakpoint continuous transmission mode is adopted, the steps S823-S827 can be circularly executed until all file metadata corresponding to album contents in the HDC equipment are transmitted and successfully stored in the terminal equipment, and then the effect of carrying out downlink increment synchronization by adopting the breakpoint continuous transmission mode is achieved.

S828: and the end side synchronization service determines that the downlink synchronization is not executed, and the current flow is ended.

Optionally, after the end side synchronization service finishes the current flow, it may determine whether to execute the uplink synchronization flow, and if so, may continue to execute the corresponding uplink synchronization procedure.

Based on the above embodiment, the terminal device can acquire and store metadata of the content in the HDC device through downlink synchronization, and is realized without using a home storage APP. When the terminal equipment is applied to the content in the HDC equipment to be accessed, the corresponding content in the HDC equipment can be obtained according to the stored metadata of the content in the HDC equipment.

Referring to fig. 9, taking content synchronized by a terminal device and an HDC device as album content as an example, the method for uplink synchronization may include:

s901: the end side synchronization service sends an uplink synchronization request to the media library, wherein the request is used for requesting uplink synchronization.

S902: the media library sends uplink synchronization confirmation information to the end side synchronization service, wherein the information is used for confirming uplink synchronization.

S903: the end side synchronization service obtains the synchronization lock from the HDC device.

In the embodiment of the application, the synchronization lock is used for controlling and realizing the effect that only one terminal device and the HDC device perform uplink and downlink synchronization in a plurality of terminal devices corresponding to the same user account at the same time. The same user account can log in a plurality of terminal devices, generate media content at the corresponding terminal devices, and synchronize the generated media content to and from the HDC device through the corresponding terminal devices. Therefore, in the embodiment of the present application, each user account has and only has one synchronization lock, and the synchronization lock is allocated by the HDC device and can be used to control the operation authority of the media content corresponding to the user account, for example, whether the uplink and downlink synchronization of the media content corresponding to the user account can be performed on the HDC device. At any time, only one terminal device corresponding to the account is allowed to have the synchronous lock at most. When the terminal equipment has the synchronous lock corresponding to the user account, the terminal equipment can perform synchronous operation on the media content corresponding to the user account, otherwise, the terminal equipment does not allow the synchronous operation on the content corresponding to the user account.

S904: the terminal side synchronization service acquires album content added in the terminal equipment from the media library and album metadata corresponding to the album content.

The terminal side synchronization service may send a request to the media library to request to acquire album content added in the terminal device and album metadata corresponding to the album content. After the media library receives the request, judging whether the stored album content contains album content added after the last uplink synchronization process is executed, if so, sending the part of album content and the album metadata corresponding to the part of album content to the end side synchronization service, if not, returning indication information without adding the album content to the end side synchronization service, and after receiving the information, the end side synchronization service can continuously acquire the album content modified or deleted in the terminal equipment and the metadata corresponding to the album content from the media library.

The terminal side synchronization service may periodically trigger to execute the step S801 and the subsequent steps, so as to periodically determine whether to execute uplink synchronization, and execute a corresponding uplink synchronization process when determining that uplink synchronization needs to be executed.

S905: and the terminal side synchronization service sends the album content added in the terminal equipment and the album metadata corresponding to the album content to the HDC equipment for storage.

Based on this, the album content newly added in the terminal device after the last execution of the uplink synchronization process can be uplink-synchronized to the HDC device.

S906: the end side synchronization service indicates the uplink synchronization progress to the media library.

The terminal side synchronization service sends album content added in the terminal equipment and album metadata corresponding to the album content to the HDC equipment, the HDC equipment stores the part of content, and sends notification information of successful synchronization to the terminal side synchronization service after the storage is successful so as to notify that the uplink synchronization of the part of content is completed successfully. After receiving the indication information, the end side synchronization service may also send notification information to the media library to notify that the uplink synchronization of the part of content is completed, so that the media library obtains an uplink synchronization progress.

In the process of sending the album content added in the terminal device and the album metadata corresponding to the album content to the HDC device, the terminal side synchronization service may also complete synchronization in a breakpoint continuous mode. The above-mentioned processes S904 to S906 may be performed in a loop until the terminal side synchronization service transmits all album contents added in the terminal device and corresponding album metadata thereof to the HDC device and successfully stores them in the HDC device.

S907: the terminal side synchronization service acquires the modified album content in the terminal equipment and the album metadata corresponding to the album content from the media library.

The terminal side synchronization service may send a request to the media library to request to acquire the modified album content and the album metadata corresponding to the modified album content in the terminal device. After the media library receives the request, judging whether the album content which is modified after the uplink synchronization process is executed last time exists in the stored album content, if so, sending the part of album content and the album metadata corresponding to the part of album content to the end side synchronization service, if not, returning indication information of the album content which is not modified to the end side synchronization service, and after receiving the information, the end side synchronization service can continuously acquire the album content deleted from the terminal equipment and the metadata corresponding to the album content from the media library.

S908: and the terminal side synchronization service sends the modified album content in the terminal equipment and the album metadata corresponding to the modified album content to the HDC equipment for updating and storing.

After the HDC device receives the modified album content and the corresponding album metadata thereof in the terminal device, the stored corresponding content is updated by utilizing the modified album content and the corresponding metadata thereof, so that the same modification as that in the terminal device is carried out on the part of content. Based on this, the album content modified after the last execution of the uplink synchronization process in the terminal device can be uplink-synchronized to the HDC device.

S909: the end side synchronization service indicates the uplink synchronization progress to the media library.

The specific reference may be made to the execution of step S906, which is not repeated here.

S910: the terminal side synchronization service acquires the identification information of the album metadata deleted from the terminal equipment from the media library.

After deleting the album content and the corresponding metadata, the media library may record the identification information of the deleted metadata, and in the uplink synchronization process, the end side synchronization service may send a request to the media library to request to obtain the identification information of the album metadata corresponding to the album content deleted in the terminal device. After the media library receives the request, if the identification information of the deleted metadata exists, the media library sends the part of identification information to the terminal side synchronization service, if the part of identification information does not exist, the terminal side synchronization service can return indication information without deleting album content to the terminal side synchronization service, and after the terminal side synchronization service receives the information, the terminal side synchronization service can continuously acquire the album content deleted in the terminal equipment and the metadata corresponding to the album content from the media library.

S911: the terminal side synchronization service transmits identification information of album metadata deleted in the terminal device to the HDC device.

The terminal side synchronization service may instruct the HDC device to delete the album metadata and the corresponding media content. After the HDC device receives the identification information, corresponding metadata and album content are determined in the stored content and deleted. Based on this, the album content deleted after the last execution of the uplink synchronization process in the terminal device can be uplink-synchronized to the HDC device, i.e., the part of the album content is also deleted in the HDC device.

S912: the end side synchronization service indicates the uplink synchronization progress to the media library.

S913: after the uplink synchronization is completed, the terminal side synchronization service acquires HDC version information from the HDC device, where the information is used to indicate version information of the latest album content in the HDC device.

S914: the end side synchronization service informs the media library of successful completion of the uplink synchronization.

When the terminal side synchronization service notifies the media library of successful completion of uplink synchronization, the terminal side synchronization service may send version information of the content synchronized from the HDC device to the media library, and store the version information in the media library.

S915: the end side synchronization service requests the HDC device to unlock the synchronization lock.

After the end side synchronization service finishes the uplink synchronization process, the end side synchronization service can request the HDC equipment to release the synchronization lock, and after the synchronization lock is released, the end side synchronization service can not execute the uplink synchronization process with the HDC equipment. If the uplink synchronization process needs to be executed with the HDC device again, the end-side synchronization service needs to request the synchronization lock from the HDC device again.

Based on the above embodiments, the terminal device can synchronize the local content to the HDC device for storage, and does not need to implement by means of a home storage APP.

2. Content access

Based on the content synchronization method provided by the embodiment, the terminal device can synchronize metadata of the content in the HDC device to the self media library for storage, and further based on the metadata, the terminal device can realize the access of the application installed in the terminal device to the content in the HDC device.

Referring to fig. 10, taking a scenario in which a third party application installed in a terminal device accesses content in an HDC device as an example, a content access method provided in an embodiment of the present application may include:

s1001: a third party application in the terminal device receives an operation by the user indicating to view the content in the HDC device.

In some embodiments of the present application, a control may be provided in the third party application for controlling the selection of the source (or range) of the access content, and the user may select the source of the access content to be the local content, or the content in the HDC device, or both the local content and the content in the HDC device by operating the control. After the user selects the source of the access content, the third party application may request the corresponding content from the media library and present it for the user to further select therefrom the particular content to view.

For example, when the user selects the source of the access content to be the local content and the content in the HDC device, there may be the following step S1002 and the subsequent steps.

S1002: the third party application sends a content retrieval request to the media library requesting retrieval of media content in the HDC device.

Wherein the third party application may interact with the media library through an access interface provided by the media library.

S1003: the media library determines whether to open the content synchronized from the HDC device to the third party application, if so, performs step S1004, otherwise, performs step S1006.

The media library may obtain, in advance, an application white list set by the user, where the application white list includes identification information of at least one third party application that allows access to content in the HDC device. When a third party application requests content in the HDC device from the media library, if the media library can acquire the identification information of the third party application and judge whether the identification information is contained in the application white list, if so, the third party application can be determined to have the authority to access the content in the HDC device, and then the content synchronized from the HDC device can be provided to the third party application. Otherwise, it may be determined that the third party application does not have the right to access the content in the HDC device, then the content synchronized from the HDC device cannot be provided to the third party application.

S1004: the media library determines whether the third party application is within the set application white list range, if so, step S1005 is executed, otherwise, step S1006 is executed.

S1005: the media library sends metadata corresponding to the local content and the content synchronized from the HDC device to the third party application.

S1006: the media library sends metadata corresponding to the local content to a third party application.

S1007: the third party application displays a content display interface, wherein the content display interface comprises information of local content of the terminal equipment and information of content in the HDC equipment.

Wherein the information may be identification information or the like. For example, when the content requested by the third party application to the media library is an image, the content presentation interface may include identification information (such as a thumbnail image) of the image locally stored in the terminal device and identification information of the image in the HDC device. The identification information of the image in the HDC device is determined by the media library according to metadata corresponding to the content in the HDC device, and the metadata may be obtained by downlink synchronization between the terminal device and the HDC device according to the method provided in the foregoing embodiment.

S1008: the third party application receives an operation by a user indicating to view a target image in the HDC device.

For example, the operation performed by the user may be that the user clicks on the identification information of the target image in the HDC device, which is displayed in the content display interface, to indicate that the user needs to view the target image.

S1009: the third party application sends an image acquisition request to the media library requesting acquisition of the target image in the HDC device.

S1010: the media library sends the image acquisition request to the end-side synchronization service.

S1011: the end-side synchronization service obtains a target image from the HDC device.

S1012: the end side synchronization service sends the target image to the media library.

S1013: the media library sends the target image to a third party application.

S1014: the third party application displays the target image.

The third party application can request the media library to notify the third party application after determining that the local content of the terminal equipment or the content synchronized by the terminal equipment from the HDC changes by registering the content change notification to the media library, so that the third party application can update correspondingly. As an alternative embodiment, after the third party application successfully registers the notification of the content change with the media library, the media library may notify the third party application of the latest local content and metadata of the content synchronized from the HDC device after each end of the uplink and downlink synchronization process.

Optionally, in the above-mentioned process, before step S1002, the following step S100a may be further included:

s100a: the third party application registers the content change notification with the media library.

After step S1005 or step S1006, the following step S100b may be further included:

s100b: the media library sends a content change notification to the third party application.

Based on the method, the third party application in the terminal equipment can acquire the information of the content in the HDC equipment without home storage APP, and the information of the local content of the terminal equipment is combined for fusion display, so that the local content of the terminal equipment or the content acquired from the HDC equipment can be displayed to the user according to user operation.

The content management method provided in the embodiment of the present application is described below by way of example with reference to specific examples.

In this example, the content accessed and processed by the scheme of the present application is described by taking images and videos as examples.

The HDC device can provide functions of storing, backing up and synchronizing files such as pictures, videos and documents. The home storage APP is a matched application of the HDC equipment and can be installed in the terminal equipment. The user can complete the initialization installation of the HDC device, the binding of the user account number, the network access and the like through the home storage APP in the terminal device. The HDC device supports isolating content uploaded and downloaded by different users according to user account numbers.

In this example, a gallery application may be installed in the terminal device, and the gallery application may serve as a fusion carrier for the content in the terminal device and the HDC device. A user can browse and manage media content (pictures and videos) stored by the HDC device in a gallery application, the gallery application can fuse and display the media content in the HDC device with local media content of the terminal device, even media content of a cloud end and media content of the distributed storage device, repeated content cannot be displayed, and therefore the user can view the media content stored in multiple ends in one application of the gallery application.

Specifically, referring to fig. 11, in the content processing scheme implemented based on the gallery application, the scheme mainly includes the following 5 links.

Link 1, uplink and downlink synchronization link

In the link, the media library deployed in the application program framework layer of the terminal equipment can call the HDC service through integration, and the media library and the HDC service cooperate to complete the uplink and downlink synchronization of the media content between the terminal equipment and the HDC equipment. Reference may be made specifically to the description of the uplink and downlink synchronization procedure in the embodiments of the present application.

Link 2, media library fusion management link

In the link, the media library provides a synchronous interface for the gallery application, so that the gallery application can be connected with the HDC service through the media library, further the media content in the HDC device is synchronized to the database of the gallery application through the HDC service, and the gallery application can finish fusion of the local media content and the media content in the HDC device.

Optionally, the media library may further include a cloud space synchronization service, and based on the cloud space synchronization service, the media library may synchronize media content in the cloud storage space. The gallery application may also obtain and fuse media content stored in the cloud storage space based on the synchronization interface of the media gallery. Optionally, the media library may further include a distributed subsystem interface, based on which the media library may interact with the distributed storage device to synchronize media content with the distributed storage device (corresponding to the same user account). The gallery application may also acquire and fuse media content stored in the distributed storage device based on the synchronization interface of the media gallery.

By way of example, as shown in fig. 12, a local database and an HDC database may be included in the media library, wherein the local database includes a local media data table for recording metadata of media contents locally stored by the terminal device and an incremental operation table. The incremental operation record table is used for recording the operation performed on the locally stored media content in the time period of the interval of the two synchronization processes, and based on the incremental operation record table, the change condition of the local media content in the time period of the interval of the two synchronization processes can be determined, so that the content to be synchronized in the uplink incremental synchronization process can be determined. The primary synchronization process comprises a primary uplink synchronization process and/or a primary downlink synchronization process. The HDC database is used to manage media content synchronized by the terminal device from the HDC device. The HDC database comprises an HDC data table and an HDC operation table, the HDC data table is used for recording metadata of media content synchronized by the terminal equipment from the HDC equipment, the HDC operation table is used for recording operations on the media content in the HDC equipment in a time period of a two-time synchronization process interval, on one hand, the HDC database can be used for carrying out downlink incremental synchronization on the HDC service, on the other hand, the HDC database can be used for determining the change condition of the media content in the HDC equipment by a gallery application and the like, and therefore display content can be updated. The content recorded by the HDC data table and the HDC operation table is obtained from the HDC equipment by the HDC service. Optionally, the home storage APP may also obtain the media content in the HDC device through an HDC database in the media library.

As shown in fig. 12, for media content, the gallery application may synchronize local data from the local database of the media gallery to the gallery, may synchronize data from the HDC database of the media gallery to the gallery application, and thus complete fusion of the local media content and the HDC media content within the gallery application. Wherein, for the acquisition of HDC media content, the gallery application does not interact directly with the HDC service, but only with the HDC database of the media gallery.

Specifically, referring to fig. 13, the related flow may include:

s1301: the gallery application registers a synchronization state listening event list with the HDC service.

Specifically, the gallery application may register a synchronization state listening event list with the application side synchronization service, and the application side synchronization service registers the synchronization state listening event list with the end side synchronization service. After the registration is successful, when the state of the uplink and downlink synchronization processes changes, the synchronization state is notified to the application side synchronization service, and then the application side service notifies the synchronization state to the gallery application, so that the gallery application can acquire the progress of the uplink and downlink synchronization processes.

S1302: after the synchronization process is finished by adopting the full-scale synchronization mode, the HDC service informs the gallery application of the state information.

S1303: the gallery application obtains HDC media content from the HDC data table of the media gallery.

S1304: the gallery application fuses the HDC media content with the local content and writes the fused HDC media content to the gallery media.

The steps S1301 to S1304 may be executed during the first synchronization between the terminal device and the HDC device, where the synchronization mode adopted in the process is a full-scale synchronization mode, and the gallery application obtains the full-scale HDC media content after the full-scale synchronization process is executed, and fuses with the local media content. In the subsequent synchronization process, an incremental synchronization mode can be adopted when the terminal equipment and the HDC equipment are synchronized. The gallery application may obtain synchronized incremental HDC media content and update existing content after the incremental synchronization process is performed.

Optionally, after the steps S1031 to S1303, the method may further include the following steps:

s1305: after the synchronization process is finished by adopting the incremental synchronization mode, the HDC service notifies the state information to the gallery application.

S1306: the gallery application queries HDC media content delta information from the HDC operation table of the media gallery.

S1307: and the gallery application correspondingly updates the stored HDC media content according to the queried incremental information.

If the incremental information is the added part of the HDC content, the gallery application fuses the added HDC media content with the local content and writes the fused content into the gallery media surface; if the incremental information is the modified part of the HDC content, the gallery application correspondingly modifies and updates the information recorded in the gallery media according to the incremental information; if the incremental information is to delete part of the HDC content, the gallery application deletes the record of the corresponding part of the HDC content in the gallery media.

In some embodiments of the present application, in the case where the terminal device adopts the synchronization method of breakpoint continuous transmission in the synchronization process during the execution of the above procedure, the synchronization process may be interrupted for some reasons. When the synchronization process is interrupted, the HDC service can inform the terminal state to the gallery application, and the gallery application can prompt a user that the synchronization process is interrupted by displaying interrupt prompt information. Meanwhile, the gallery application can provide a control for triggering the starting of the synchronization process, and after the user determines that the synchronization process is interrupted according to the interruption prompt information, the user can manually control to continue synchronization through operating the control. After the gallery application receives the user's operation, it instructs the HDC service to resume execution of the synchronization process.

Optionally, in the process of executing the above flow, the terminal device may also execute the media content synchronization process in the cloud. For example, a cloud synchronization service may be included in the terminal device to complete media content synchronization with the cloud. However, the operation of the cloud synchronization service may increase power consumption of the terminal device, and even affect the normal operation of the HDC service, so that the synchronization process between the terminal device and the HDC device is interrupted. In this scenario, between the above step S1301 and step S1302, the following steps may be further included:

s130a: the HDC service negotiates power consumption management and control residual amount with the cloud synchronization service.

S130b: when the HDC service determines that the power consumption is limited, the execution of the synchronization process is interrupted.

S130c: the HDC service notifies the gallery that the application synchronization process is interrupted.

S130d: the gallery application displays a prompt message for prompting the synchronization process to be interrupted.

S130e: the gallery application receives operations performed by a user that indicate a resumption of the synchronization process.

S130f: the gallery application sends indication information to the HDC service indicating that the synchronization process is resumed.

S130g: the HDC service continues to perform the synchronization process.

Based on the above process, the user can control the execution progress of the synchronization process, and further the user experience is improved.

Link 3, synchronization status notification link

In the link, the HDC service may provide a synchronization status interface for the gallery application, and based on the interface, the HDC service may notify the gallery application of a progress of uplink and downlink synchronization with the HDC device, and the gallery application may display information of the synchronization status, so that a user perceives the synchronization progress.

Link 4, gallery fusion management link

In this link, the data management service in the gallery application may perform fusion management on the local media content, the content synchronized from the HDC device, the content synchronized from the cloud and the distributed device, and the like.

The gallery application may, for example, write operations (including offline operations) performed by a user on the HDC media content in the gallery application to the media gallery via a synchronization interface provided by the media gallery, where the media gallery performs corresponding records via the HDC operation table, and may synchronize to the HDC device in the next synchronization process.

Link 5, fusion display link

Based on link 5, the gallery application may perform fusion display and subsequent processing on local media content, content synchronized from the HDC device, content synchronized from the cloud and the distributed device, and the like. By way of example, gallery applications may perform fusion display of local media content and HDC media content, including fusion display of album presentation interfaces, fusion display of image presentation interfaces, album filter display, uplink status icon display, downlink synchronization progress status display, and the like. The gallery application may also perform a synchronous album scope setting including whether to present an HDC synchronous setting entry, an album setting list independent of the cloud synchronous album scope, and the like. The gallery application may also delete logical adaptations, delete logical adaptations for different pages and different filter conditions for albums, etc. The gallery application may also perform intelligent gallery data source adaptation such that the data sources that the intelligent gallery may analyze and present include HDC media content, and the like.

In one possible example, when a user opens a gallery application, the terminal device may display the interface shown in fig. 14a, which may include icons of at least one album therein. Each album contains at least one local image and/or at least one HDC image, and when a user clicks an icon of one album, the terminal device can display a thumbnail of the image contained in the album. When the user clicks a certain thumbnail, the terminal device can enlarge and display the original image corresponding to the thumbnail. The terminal equipment can acquire the thumbnail of the HDC album and the HDC image according to metadata acquired from the HDC equipment in the synchronization process.

For example, when the user clicks on the album "all photos" shown in fig. 14a, the terminal device may display the image display interface shown in fig. 14b, which may include thumbnails of the local images and the HDC images in all other albums. The terminal device may perform overall sorting on the local image and the thumbnail of the HDC image according to the sorting manner selected by the user (for example, a sorting manner according to standards such as creation time, file name, file size, etc.), and then perform fusion display. For example, in the interface shown in fig. 14b, the thumbnails a to c, e, g to i may be thumbnails of the local images, and the thumbnails d, f may be thumbnails of the HDC images. Optionally, the interface may further incorporate a thumbnail of an image synchronized by the display terminal device from other storage devices, for example, a thumbnail of a cloud image, etc.

Further, the terminal device may add a control for displaying the images for screening display in the image display interface, so that the user may select to view the images after filtering or screening the local image and the HDC image. For example, a screening control may be included in an image display interface as shown in FIG. 14 b. And the user can trigger the process of screening and displaying the displayed thumbnail by the terminal equipment through operating the screening control. When the user clicks on the filter control shown in fig. 14b, the terminal device may display an interface shown in fig. 14c, in which controls for selecting different types of images are included, such as a control for selecting a local image (a "local" control shown in fig. 14 c), a control for selecting an HDC image (a "home storage center" control shown in fig. 14 c), and the like. When the user clicks on the control of the "home storage center", the terminal device may display the interface shown in fig. 14d, which includes only the thumbnail of the HDC image.

Of course, as an alternative embodiment, the terminal device may also display the thumbnail images of the local image and the HDC image in different areas directly in the interface shown in fig. 14b, so that the user directly and explicitly distinguishes the image sources.

In one possible example, the terminal device may add a switch for controlling HDC synchronization, such as the "home storage synchronization" control shown in fig. 14e, to the setup interface of the gallery. When a user turns on the switch of the HDC synchronization, the terminal equipment can periodically synchronize media contents such as pictures and videos with the HDC equipment, and the information of the pictures and videos obtained by the synchronization of the HDC equipment and the local image video information in the gallery application are fused and displayed.

Further, the terminal device may further provide a selection control for selecting an album synchronization range, for example, after the user clicks on the "home storage synchronization" control shown in fig. 14e, the terminal device may display an interface shown in fig. 14f, where the interface includes selection controls corresponding to different albums, and the user may select which albums to perform content synchronization with the HDC device. For example, if only the album of "camera" is selected, when the terminal device performs synchronization with the HDC device, in the uplink synchronization process, only the image in the album of "camera" is uplink-synchronized to the HDC device, and after uplink synchronization, the album of "camera" and the image therein are also stored in the HDC device. In the downlink synchronization process, the terminal device only downlink-synchronizes the image in the photo album, namely the camera, in the HDC device to the local.

Optionally, in a state that the HDC synchronization switch is turned on, the terminal device may also simultaneously display information for indicating a synchronization progress, and when the synchronization progress is in synchronization, the terminal device may temporarily prohibit access and operation of the user to the content in the HDC album, and prompt the user to prohibit corresponding operations and the like in the current synchronization process when the user attempts to access and operate the content in the HDC album. When the synchronization progress is synchronized, the terminal device can allow and respond to the access and operation of the user to the content in the HDC album.

Referring to fig. 15, based on the above example, a flow of a content usage method provided in an embodiment of the present application may include:

s1501: the terminal equipment displays a first interface, wherein the first interface is an interface applied in the terminal equipment.

The application in the terminal device may be a system application or a third party application.

S1502: and the terminal equipment receives the operation of the user on the first interface, and the operation is used for triggering the selection of the image.

The operation is performed by the user in a system application or a third party application of the terminal equipment. Based on this operation, the user may trigger a flow of capturing and viewing images in the gallery application in the system application or the third party application.

By way of example, fig. 16a shows a schematic view of a first interface. As shown in fig. 16a, the first interface may be a display interface of a memo application, where the interface includes an image selection control, where the control is used to trigger an image selection to add an image to the memo note, and then an operation performed by the user on the first interface may be an operation performed by the user to click on the image selection control in the first interface.

S1503: the terminal equipment displays a second interface, wherein the second interface comprises a gallery selection control, and the control is used for selecting to acquire images from a gallery application.

Exemplary, fig. 16b is a schematic diagram of a second interface. After the user clicks the picture selection control shown in fig. 16a, the terminal device may display a second interface shown in fig. 16b, where the interface includes at least a gallery selection control, and may further include other selection controls for selecting other manners of acquiring an image.

S1504: and the terminal equipment receives the operation of the user on the second interface, wherein the operation is used for selecting to acquire the image from the gallery application.

Illustratively, this operation may be an operation in which the user clicks the gallery selection control shown in FIG. 16 b.

The terminal device may execute the above steps S1501 to 1503 through an installed system application or a third party application.

S1505: the terminal device displays a third interface including at least one local image and at least one thumbnail of the HDC image.

The local image is an image stored locally in the terminal device, and the HDC image is an image stored in the HDC device. The thumbnail is used as identification information of the image, so that the user can conveniently select the image. The thumbnail of at least one HDC image may be acquired from the HDC device after the terminal device synchronizes with the HDC device based on the synchronization manner described in the above embodiments.

Optionally, the third interface further includes a source identifier corresponding to each image, where the source identifier is used to indicate that a source of the image is a terminal device local or HDC device.

For example, after the user clicks the gallery selection control shown in fig. 16b, the terminal device may display a third interface shown in fig. 16c, where the third interface includes thumbnails of the local image and the HDC image, where the thumbnails a to c, e, g to i are thumbnails of the local image, and the thumbnails d and f are thumbnails of the HDC image.

In some embodiments of the present application, a system application or a third party application in the terminal device may call an image selector (picture) component of the gallery application through a Pick Action, and the gallery application fuses and presents the local content and the HDC content in the image selector when the image selector component is called, so that a user may select an image stored locally and an image stored in the HDC device, which is more convenient for the user to select an image simply, quickly and conveniently.

S1506: the terminal device receives an operation performed by a user on the third interface, the operation being used for selecting one HDC image.

Wherein the operation is an operation in which the user selects a thumbnail of one HDC image in the first interface.

For example, this operation may be an operation in which the user selects a thumbnail of one HDC image in the interface shown in fig. 16c and clicks "done".

S1507: the terminal device downloads the HDC image selected by the user from the HDC device.

Specifically, the gallery application in the terminal device may determine corresponding metadata according to the thumbnail information of the HDC image selected by the user, obtain a download API of the HDC image according to the corresponding metadata, and drive the HDC service to download the HDC image from the HDC device by calling the download API.

After the terminal device downloads the HDC image from the HDC device, the downloaded HDC image may be stored locally, and a uniform resource identifier (uniform resource identifier, URI) of the HDC image locally may be provided to the system application or the third party application. The system application or third party application may also continue to access the HDC image or perform other operations on the HDC image based on the URI in subsequent processes.

Optionally, before downloading the HDC image selected by the user from the HDC device, the terminal device may also prompt the user to confirm whether to download the HDC image, and if it is determined that the HDC image is downloaded according to the information fed back by the user, the terminal device performs an operation of downloading the image from the HDC device.

S1508: the terminal device displays a fourth interface including one HDC image selected by the user.

For example, after the user selects a thumbnail (thumbnail d) of one HDC image in the interface shown in fig. 16c and clicks "complete", the terminal device may display a fourth interface as shown in fig. 16d, which increases the image selected by the user (image d corresponding to thumbnail d) compared to the first interface shown in fig. 16a, achieving the effect of adding the image in the HDC device in the memo. For the user, the user can realize the effect only by operating in the memo application, and the whole process is very simple and convenient to operate, so that the use experience of the user can be obviously improved.

It should be noted that, the specific implementation process provided by the above examples is merely an illustration of a process flow applicable to the embodiments of the present application, where the execution sequence of each step may be adjusted accordingly according to actual needs, and other steps may be added or some steps may be reduced. The method flows provided by the above examples may also be performed in combination with the method flows provided by other examples, so as to implement the solutions provided by the embodiments of the present application.

Based on the above embodiments and the same concept, the present application further provides a content management method applied to a first electronic device, where the first electronic device includes a first service and a first application, as shown in fig. 17, the method includes:

s1701: the first service acquires first information and second information and stores the first information and the second information; wherein the first information is used to identify first media content stored in the first electronic device and the second information is used to identify second media content stored in a second electronic device.

The first electronic device may be the terminal device described in the foregoing embodiment, and the second electronic device may be the HDC device described in the foregoing embodiment.

In some embodiments of the present application, the first application is any application installed in the first electronic device. The first service is located at an application framework layer in an operating system of the first electronic device. The first service may include the media library and the HDC service described in the above embodiments, and the first application may be a system application or a third party application described in the above embodiments.

In some embodiments of the present application, the first application may obtain the first information and/or the second information from the first service through a first interface provided by the first service. Illustratively, the first interface may be an access interface provided by the media library shown in fig. 5 in the above embodiment.

In some embodiments of the present application, the first media content and the second media content may be images or videos, and the first information and the second information may be thumbnails described in the above embodiments.

In some embodiments of the present application, the first metadata corresponding to the first media content includes first information, the second metadata corresponding to the second media content includes second information, and the first service may obtain the first metadata and store the first metadata, and obtain the second metadata and store the second metadata, so as to achieve the effect of obtaining the first information and the second information and storing the first information and the second information.

Wherein the first metadata and the first media content are content stored locally at the first electronic device, which may be obtained directly from the local by the first service. For the second metadata and the second media content, the first service may obtain these content by performing downstream synchronization with the second electronic device.

In the solution provided in the embodiments of the present application, the first service may perform the synchronization process with the second electronic device periodically, or the first service may perform the synchronization process with the second electronic device when the stored media content or/and metadata changes. The synchronization process includes a downlink synchronization process and/or an uplink synchronization process. When the synchronization process includes a downlink synchronization process and an uplink synchronization process, the downlink synchronization process may be performed first, the uplink synchronization process may be performed after the uplink synchronization process, or the uplink synchronization process may be performed first, and the downlink synchronization process may be performed after the uplink synchronization process. The case that the media content stored in the first electronic device changes may be that the first electronic device adds the stored media content, or that the media content stored in the first electronic device is modified or deleted, or that the metadata stored in the first electronic device synchronized from the second electronic device is deleted.

The first service may trigger downlink and/or uplink synchronization when determining the start time of the arrival period, or the first service may trigger downlink and/or uplink synchronization when determining that the stored media content and/or the stored metadata from the second electronic device changes. After triggering downlink synchronization, the first service may send synchronization indication information to the second electronic device, where the synchronization indication information is used to indicate the second electronic device to send downlink synchronization information to the first service, and the downlink synchronization information may be used to indicate at least one of the following: transmitting metadata corresponding to the added media content in the second electronic device to the first service; transmitting the modified metadata or the metadata corresponding to the modified media content in the second electronic device to the first service; and indicating the metadata corresponding to the media content deleted in the second electronic equipment to the first service. After the second electronic device sends corresponding information to the first service according to the indication, the first service can determine the change of the media content and the metadata in the second electronic device according to the information, and then correspondingly update the metadata stored by the second electronic device.

In one possible scenario, the second media content may be newly added media content in the second electronic device after the previous downlink synchronization process, and the first service may instruct the second electronic device to send downlink synchronization information to the first service when determining to perform the downlink synchronization process. After receiving the indication, the second electronic device determines that the second media content is media content added after the previous downlink synchronization process, and then the second electronic device may send downlink synchronization information including the second metadata and the first indication information to the first service, where the first indication information is used to indicate: the second metadata is metadata corresponding to the media content added in the second electronic device. The first service may determine that only the second metadata needs to be stored according to the received first indication information, and the first service stores the second metadata.

In another possible scenario, the second media content may be media content that the second electronic device modified the third media content after the previous synchronization process. Because the third media content is the media content stored by the second electronic device before the previous synchronization process, the first service may acquire third metadata corresponding to the third media content from the second electronic device and store the third metadata in the previous downlink synchronization process. And after the second electronic equipment modifies the third media content to obtain the second media content, the third metadata is correspondingly updated into the second metadata. Therefore, when the first service determines to perform the present downlink synchronization procedure, it needs to acquire the second metadata from the second electronic device to update the third metadata stored previously. The first service may instruct the second electronic device to send the downlink synchronization information to the first service. After the second electronic device receives the indication, the second media content is determined to be the modified third media content, and then the downlink synchronous information containing the second metadata and the second indication information can be sent to the first service; wherein the second indication information is used for indicating: the second metadata is metadata obtained after the third metadata is modified. The first service may determine to update the stored third metadata with the second metadata according to the second indication information, and the first service may update the third metadata to the second metadata. When the first service updates the third metadata to the second metadata, the corresponding content in the third metadata may be replaced with a content different from the content in the third metadata, that is, only the content changed in the third metadata may be replaced. Alternatively, the first service may delete the third metadata first and then store the second metadata, or may update the third metadata to the second metadata.

In the above method, the second electronic device may only modify the third metadata corresponding to the third media content into the second metadata, where the third media content may be unchanged, and the second media content is the third media content. After the first service triggers the downlink synchronization process, the second electronic device also needs to indicate the second metadata and the information that the second metadata is the modified third metadata to the first service according to the method, so that the first service updates the stored third metadata into the second metadata.

In yet another possible scenario, after the first service acquires and stores the second metadata, if the second electronic device deletes the second media content and the corresponding second metadata, the first service may instruct the second electronic device to send downlink synchronization information to the first service when the first service performs the downlink synchronization process again. After the second electronic device receives the indication information, if it is determined that the second media content and the second metadata are deleted, downlink synchronization information including third indication information is sent to the first service, where the third indication information is used to indicate: and the second metadata is metadata corresponding to the media content deleted in the second electronic equipment. The first service may determine to delete the second metadata according to the third indication information, and delete the stored second metadata. Optionally, the third indication information is included in the above synchronization indication information, and the first service may send the third indication information to the second electronic device by sending the above synchronization indication information.

S1702: the first application obtains the first information and/or the second information from the first service.

After the first service obtains and stores the first metadata and the second metadata, the first application may access the first metadata and the second metadata through a first interface provided by the first service, further determine corresponding first information and second information, and may display the first information and the second information to a user, so that the user may know contents stored in the first electronic device and the second electronic device.

S1703: the first application displays the first information and/or the second information.

In some embodiments of the present application, after the first application displays the first information and the second information, or after the first application displays the second information, the user may instruct the first application to store the second media content identified by the second information locally to the first electronic device by performing a corresponding operation. The first application may instruct the first service to retrieve and store the second media content, which the first service may retrieve and store from the second electronic device, and may also provide to the first application. After the first service provides the second media content to the first application, the first application may display the media content to the user. And may determine to modify or delete the second media content and the second metadata based on the user performed operation.

Specifically, when the first application modifies the second media content into the seventh media content according to the operation of the user, the first application instructs the first service to update the second media content into the seventh media content and update the second metadata into fourth metadata corresponding to the seventh media content. The first service updates the stored second media content to the seventh media content and updates the stored second metadata to the fourth metadata according to the instruction of the first application. After updating the second media content into the first media content, the first service may trigger to execute an uplink synchronization process, where the first service may send the seventh media content, the fourth metadata, and the fifth instruction information to the second electronic device; wherein the fifth indication information is used for indicating: updating the stored second media content to the seventh media content, and updating the stored second metadata to the fourth metadata. The second electronic device may update the stored second media content to the seventh media content and the stored second metadata to the fourth metadata according to the indication of the first service.

When the first application receives an instruction from a user to delete the second media content and the second metadata stored in the first electronic device and the second electronic device, the first application may first determine whether the second media content is already stored in the first electronic device, if so, the first application instructs the first service to delete the second media content and the second metadata, and the first service deletes the stored second media content and the second metadata according to the instruction. Otherwise, the first application may instruct the first service to delete the second metadata only, and the first service deletes the stored second metadata according to the instruction. The first service may trigger the uplink synchronization process to be performed after deleting the stored second media content and the second metadata, or after deleting the second metadata. In the process of performing uplink synchronization, the first service instructs the second electronic device to delete the stored second media content and the second metadata.

In some embodiments of the present application, the first electronic device further includes a second application, and after the step S1701, the method may further include the following steps S1704 to S1705:
