[0002] At present, solutions such as Bluetooth mutual transmission or network disk sharing can realize file sharing between two terminal devices. However, in the process of sharing files of terminal device A between the existing terminal device A and terminal device B, the files to be shared need to be stored locally on terminal device B.

Obviously, the above solution requires terminal device A to manually select images, which is cumbersome. Moreover, if the number of files to be shared is large, for example, all images of terminal device A are shared, all images of terminal device A need to be transferred to terminal device B, which not only takes up too much storage space of terminal device B, but also consumes a lot of time.

[0054] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system shown as an example, the communication equipment may include network equipment and terminal equipment with communication functions. The network equipment and terminal equipment may be specific equipment in the embodiments of the present application and will not be repeated here. The communication equipment may also include other equipment in the communication system, such as network controllers, mobile management entities and other network entities, which are not limited to the embodiments of the present application.

[0055] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0056] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0057] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0058] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0059] At present, solutions such as Bluetooth mutual transmission or network disk sharing can realize file sharing between two terminal devices. However, in the process of sharing the files of terminal device A, the existing terminal device A and terminal device B need to store the files to be shared locally on terminal device B. For example, if several target images stored by terminal device A are shared, terminal device B needs to receive the target images sent by terminal device A and save them locally, so as to realize image sharing. Obviously, the above solution requires terminal device A to manually select images, which is cumbersome. At the same time, it also needs to occupy the local storage space of terminal device B. If the files to be shared are only temporary files, the storage space will inevitably be wasted. Moreover, if the number of files to be shared is large, for example, all the images of terminal device A are shared, all the images of terminal device A need to be transferred to terminal device B, which will not only occupy storage space, but also consume a lot of time. The operation is also cumbersome, which seriously reduces the user experience.

[0060] Based on this, the disclosed solution proposes a multimedia data processing method to solve the defects of the above-mentioned existing solutions and improve user experience.

[0061] Figure 2 This is a schematic flow chart of a multimedia data processing method according to an embodiment of the present application. Figure 1 . This method can optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0062] S210: When the first terminal device and the second terminal device are in a multimedia sharing state, the first terminal device sends a file scanning request to the second terminal device.

[0063] Here, the file scanning request is used to request to obtain the target multimedia data stored in the second terminal device. In other words, the first terminal device requests to share the target multimedia data stored in the second terminal device.

[0064] S220. The first terminal device obtains target description information for describing target multimedia data stored in the second terminal device.

[0065] S230: The first terminal device displays the target description information.

[0066] It can be understood that the target description information refers to the relevant information describing the target multimedia data stored in the second terminal device. The data volume of the target description information is much smaller than the data volume of the target multimedia data itself. For example, the target description information can be specifically the basic information of the target multimedia data, such as file name, thumbnail, and any other information that can summarize the target multimedia data.

[0067] In this way, since the first terminal device can obtain the target description information of the target multimedia data stored in the second terminal device, the purpose of sharing the target multimedia data stored in the second terminal device can be achieved; and compared with the existing solution that requires the storage of the full amount of target multimedia data to achieve the sharing of the full amount of data, the disclosed solution can effectively save the storage space of the first terminal device, effectively reduce the data transmission time, and improve the data transmission efficiency. Even if the multimedia data to be shared is a temporary file, it does not occupy too much storage space of the first terminal device.

[0068] In addition, the disclosed solution is easy to operate and not complicated, and does not require the user to manually select the multimedia data to be shared multiple times. Therefore, the disclosed solution effectively improves the user experience.

[0069] Figure 3 This is a schematic flow chart of a multimedia data processing method according to an embodiment of the present application. Figure 2 . This method can optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0070] S310: When the first terminal device and the second terminal device are in a multimedia sharing state, the second terminal device receives a file scanning request sent by the first terminal device.

[0071] Here, the file scanning request is used to request to obtain the target multimedia data stored in the second terminal device, thereby laying a foundation for sharing the target multimedia data.

[0072] S320: The second terminal device generates target description information for describing the target multimedia data in response to the file scanning request.

[0073] S330. The second terminal device sends the target description information.

[0074] In this way, the target multimedia data can be effectively shared. Moreover, compared with the existing solution that requires storing the full amount of target multimedia data to share the full amount of data, the disclosed solution can effectively reduce the data transmission time, and the operation is simple and non-cumbersome, without the need for users to manually select operations multiple times, thereby effectively improving the user experience.

[0075] In one embodiment, after the first terminal device obtains the target description information, the first terminal device may also store the target description information in a first multimedia database; here, the first multimedia database also stores the first multimedia data of the first terminal device. That is, the first terminal device stores the target description information obtained from the second terminal device in its own multimedia database for storing the first multimedia data. For example, if the operating system of the first terminal device is an Android system, the target description information and its own first multimedia data may be stored in the MediaProvider, so that the user of the first terminal device can view them through applications such as a file manager or an album.

[0076] In one embodiment, while the first terminal device is displaying the target description information, the first terminal device may also send a data request instruction in response to a selection operation (such as a click operation, such as a touch operation, etc.) on the first sub-description information contained in the target description information; here, the data request instruction is used to request to obtain the multimedia data corresponding to the first sub-description information from the second terminal device; accordingly, the second terminal device receives the data request instruction and obtains the multimedia data corresponding to the first sub-description information of the target description information, such as obtaining the multimedia data corresponding to the first sub-description information from a database (which may be called second multimedia data) storing the target multimedia data on the second terminal device, and then sending the multimedia data corresponding to the first sub-description information to the first terminal device; further, the first terminal device obtains and displays the multimedia data corresponding to the first sub-description information.

[0077] It can be understood that, when the first terminal device displays the target description information, if the user of the first terminal device selects specific content of interest based on the displayed target description information, for example, performing a selection operation on the first sub-description information contained in the displayed target description information, then the first terminal device generates a data request instruction according to the selection operation, and sends the data request instruction to the second terminal device, so as to obtain the multimedia data corresponding to the first sub-description information from the second terminal device and display it to the user, so that the user can further browse the specific content of the multimedia data, thereby further satisfying the user's sharing needs.

[0078] In one implementation, in the case where the first terminal device and the second terminal device are in a multimedia sharing state as described above, the first terminal device sends a file scanning request to the second terminal device (that is, S210 described above), specifically including:

[0079] When the first terminal device receives the multimedia sharing authorization information sent by the second terminal device, the first terminal device sends a file scanning request to the second terminal device.

[0080] Accordingly, in one embodiment, in the case where the first terminal device and the second terminal device are in the multimedia sharing state as described above, the second terminal device receives the file scanning request sent by the first terminal device (that is, S310 described above), which specifically includes:

[0081] When the second terminal device successfully sends the multimedia sharing authorization information, the second terminal device receives the file scanning request sent by the first terminal device.

[0082] That is to say, before the first terminal device sends a file scanning request to the second terminal device, the second terminal device needs to perform sharing authorization on the first terminal device and send multimedia sharing authorization information; in other words, the second terminal device needs to agree that the first terminal device shares its own target multimedia data, and when agreeing that the first terminal device shares its own target multimedia data, the second terminal device sends multimedia sharing authorization information, and then the first terminal device sends a file scanning request (such as generating a cross-device multimedia file scan) after receiving the multimedia sharing authorization information sent by the second terminal device, so that after the second terminal device receives the file scanning request sent by the first terminal device, it scans the target multimedia data stored in itself and obtains the target description information, so that the first terminal device can effectively realize cross-device multimedia file scanning, and then realize cross-device multimedia sharing, and the process is simple and the operation is not cumbersome, which effectively improves the user experience.

[0083] In one implementation, the first terminal device may also establish a target channel with the second terminal device, and then share multimedia data through the target channel; specifically, in the above-mentioned case where the first terminal device receives the multimedia sharing authorization information sent by the second terminal device, the first terminal device sends a file scanning request to the second terminal device, specifically including:

[0084] When the target channel between the first terminal device and the second terminal device is established, the first terminal device receives the multimedia sharing authorization information sent by the second terminal device through the target channel, so as to put the first terminal device and the second terminal device in a multimedia sharing state, so as to facilitate the sharing of multimedia data in the multimedia sharing state. Further, when the first terminal device receives the multimedia sharing authorization information, it sends a file scanning request through the target channel, and then obtains the target description information used to describe the target multimedia data stored by the second terminal device through the target channel.

[0085] Accordingly, in one implementation manner, in the above-mentioned case where the second terminal device successfully sends the multimedia sharing authorization information, the second terminal device receives the file scanning request sent by the first terminal device, specifically including:

[0086] When the target channel between the first terminal device and the second terminal device is established, the second terminal device sends multimedia sharing authorization information through the target channel, so as to put the first terminal device and the second terminal device in a multimedia sharing state, so as to facilitate the sharing of multimedia data in the multimedia sharing state. Further, when the second terminal device successfully sends the multimedia sharing authorization information, the second terminal device receives the file scanning request sent by the first terminal device through the target channel, and then after generating the target description information for describing the target multimedia data, sends the target description information through the target channel.

[0087] That is to say, before the second terminal device sends multimedia sharing authorization information to the first terminal device, it is necessary to establish a target channel between the first terminal device and the second terminal device, so that the multimedia sharing authorization information is transmitted through the target channel. For example, the second terminal device sends the multimedia sharing authorization information through the target channel, and accordingly, the first terminal device receives the multimedia sharing authorization information through the target channel, and then after receiving the multimedia sharing authorization information, sends a file scanning request through the target channel. In this way, it is convenient for the second terminal device to receive the file scanning request through the target channel to perform multimedia data scanning, and send the obtained target scanning information to the target description information through the target channel, so as to realize multimedia sharing across devices. Moreover, the process is simple and the operation is not cumbersome. There is no need for the user to manually select the content to be shared, thereby effectively improving the user experience.

[0088] Here, the target channel can be established based on the cross-device underlying communication protocol. For example, in one example, a wireless network communication technology (Wi-Fi) channel or a Bluetooth channel can be established between the first terminal device and the second terminal device. In this way, multimedia sharing authorization information is sent through the Wi-Fi channel or the Bluetooth channel, thereby putting the first terminal device and the second terminal device in a multimedia sharing state, laying a channel foundation for realizing the sharing of multimedia data.

[0089] In one implementation, in order to further meet user needs and enhance the user's sense of control, an interface interaction method can also be used to prompt the user of the second terminal device whether to agree to multimedia sharing. That is, when the target channel between the first terminal device and the second terminal device is established, the second terminal device sends multimedia sharing authorization information through the target channel, specifically including:

[0090] The second terminal device displays a second prompt message; wherein the second prompt message is used to prompt whether to authorize the first terminal device to share its own target multimedia data;

[0091] The second terminal device responds to the confirmation operation on the second prompt information and sends the multimedia sharing authorization information through the target channel when it is determined that the target channel between the first terminal device and the second terminal device is established.

[0092] That is to say, the second terminal device displays a prompt message to prompt the user of the second terminal device whether to authorize the first terminal device to share its own target multimedia data, and then triggers a confirmation operation, such as clicking a confirmation button, when confirming that the user agrees to the first terminal device sharing its own target multimedia data. At this time, the second terminal device can initiate an instruction to establish a target channel, such as actively turning on the Bluetooth function, and when it is determined that the target channel between the first terminal device and the second terminal device has been established, send multimedia sharing authorization information through the target channel to inform the user of the consent to the first terminal device to share its own target multimedia data.

[0093] Accordingly, in one implementation, in order to further meet user needs and enhance the user's sense of control, an interface interaction method can also be used to prompt the user of the first terminal device whether to agree to multimedia sharing. That is, when the first terminal device described above receives multimedia sharing authorization information, sending a file scanning request through the target channel can specifically include:

[0094] The first terminal device displays first prompt information when receiving the multimedia sharing authorization information; the first prompt information is used to prompt whether to share the target multimedia data of the second terminal device;

[0095] The first terminal device sends a file scanning request through the target channel in response to a confirmation operation on the first prompt information.

[0096] That is to say, when the target channel between the first terminal device and the second terminal device is established, and the first terminal device receives the multimedia sharing authorization information sent by the second terminal device through the target channel, the first terminal device can also display a prompt message to prompt the user of the first terminal device whether to share the target multimedia data of the second terminal device, and then trigger a confirmation operation when confirming that the user agrees to share the target multimedia data of the second terminal device, such as clicking a confirmation button to generate a file scanning request, and sending the file scanning request through the target channel to perform cross-device multimedia file scanning and realize cross-device multimedia sharing. The process is simple and the operation is not cumbersome, which effectively improves the user experience.

[0097] To sum up, in the case of authorized sharing across devices in the disclosed solution, the user obtains target description information through the first terminal device, and then calls the multimedia data in the second terminal device. In this way, the user does not need to select the files to be shared each time when sharing. It only needs to confirm whether to share when establishing a cross-device connection. The operation is simple and the transmission speed of shared files across devices is improved. In addition, the shared files do not occupy unnecessary local storage controls, further improving the user experience.

[0098] In this way, the disclosed solution can utilize the second terminal device to provide multimedia sharing authorization information to the first terminal device, and then generate and send target description information to the first terminal device, so that the user of the first terminal device can retrieve and view the multimedia data; in this way, the transmission speed of shared files across devices is improved, and the operation is simple. In addition, the shared files do not occupy unnecessary local storage controls, further improving the user experience.

[0099] The following is a further detailed description of the disclosed solution in conjunction with specific examples; the disclosed solution proposes a multimedia data processing method.

[0100] In this example, the operating systems used by the first terminal device and the second terminal device can both be Android systems. At this time, the two terminal devices can establish a connection based on the connection components in their respective Android systems to obtain the target channel, thereby realizing cross-device data transmission.

[0101] The following description is made by taking the second terminal device sharing multimedia data with the first terminal device as an example;

[0102] Specifically, Figure 4 and Figure 5 As shown, the core steps implemented by the disclosed solution include:

[0103] Step S510: The second terminal device displays second prompt information. Here, the second prompt information is used to prompt whether to authorize the first terminal device to share its own target multimedia data, for example, to display whether to share multimedia data.

[0104] Step S511: The second terminal device initiates a target channel establishment instruction in response to a confirmation operation on the second prompt information, for example, turning on Bluetooth.

[0105] It is understandable that the target channel of the first terminal device and the second terminal device can also be a Wi-Fi channel. In this case, if the second terminal device has successfully accessed the Wi-Fi, there is no need to initiate an instruction to establish the target channel. When it is determined that the target channel (such as the Wi-Fi channel) between the first terminal device and the second terminal device has been established, the multimedia sharing authorization information can be directly generated and sent.

[0106] In a specific example, the second terminal device responds to a confirmation operation for the second prompt information by providing the interface information of its own connection component, such as the interface information of the connection software development kit (SDK), to the first terminal device, for example, providing the connection component of the first terminal device, so that the two terminal devices use their respective connection components to establish a connection between the two terminal devices to achieve cross-device data transmission; accordingly, after receiving the interface information of the connection component of the second terminal device, the first terminal device establishes a connection between its own connection component and the connection component of the second terminal device to obtain the target channel.

[0107] It should be pointed out that in one example, the second terminal device can also display a prompt message about whether to establish a cross-device connection channel. At this time, when the confirmation operation (i.e., establishing a cross-device connection channel) is obtained, the interface information of its own connection component, such as the interface information of the connection SDK, is provided to the connection component of the first terminal device, so that the two terminal devices use their respective connection components to establish the target channel between the two terminal devices. Furthermore, in a specific example, after the MediaProvider component in the Android system of the second terminal device receives the message that the target channel is established through the connection SDK, it generates a trigger message to trigger the display of the second prompt message.

[0108] Step S512: When determining that the target channel between the first terminal device and the second terminal device is established, the second terminal device generates multimedia sharing authorization information.

[0109] Step S513: The second terminal device sends multimedia sharing authorization information through the target channel.

[0110] Step S514: When the first terminal device receives the multimedia sharing authorization information sent by the second terminal device through the target channel, the first terminal device displays first prompt information; the first prompt information is used to prompt whether to share the multimedia data of the second terminal device.

[0111] Step S515: The first terminal device sends a file scanning request through the target channel in response to a confirmation operation on the first prompt information.

[0112] Step S516: The second terminal device generates target description information for describing the target multimedia data in response to the file scanning request.

[0113] For example, after the first terminal device receives a message indicating that the target channel has been established through the connection SDK, and confirms that the multimedia data of the second terminal device is shared, the MediaProvider component of the first terminal device initiates a request for a cross-device multimedia file scan (i.e., a file scan request). Correspondingly, the second terminal device responds to the request for a cross-device multimedia file scan, performs a multimedia file scan, and obtains the target description information after the scan.

[0114] Step S517: The second terminal device sends the target description information through the target channel.

[0115] Step S518: The first terminal device receives the target description information through the target channel.

[0116] Here, the first terminal device stores the target description information in a first multimedia database; wherein the first multimedia database also stores the first multimedia data of the first terminal device. Accordingly, the user of the first terminal device can view the target multimedia data of the second terminal device in the first terminal device through an application such as a file manager or an album.

[0117] Step S519: When displaying the target description information, the first terminal device sends a data request instruction through the target channel in response to a selection operation on the first sub-description information contained in the target description information; the data request instruction is used to request to obtain the multimedia data corresponding to the first sub-description information from the second terminal device.

[0118] In a specific example, since the target description information has been stored in the first multimedia database, the target channel may not be used in the process of displaying the target description information. In other words, the target channel may be disconnected. Based on this, the first terminal device may detect whether the target channel is in a connected state in response to the selection operation of the first sub-description information included in the target description information, and then send a data request instruction through the target channel if it is confirmed to be in a connected state. Alternatively, if it is determined that it is not in a connected state, initiate an instruction to establish the target channel, and then send a data request instruction through the target channel if it is determined that the target channel is established.

[0119] In a specific scenario, the file system in the MediaProvider component of the first terminal device, such as the kernel (Daemon) module of Fuse (filesystem in userspace), can implement a cross-device file system interface based on the interface of the connection SDK. Based on this, after the first terminal device initiates a data request instruction, it can directly trigger the acquisition of cross-device file data to obtain the multimedia data corresponding to the first sub-description information requested by the data request instruction.

[0120] Step S520: The second terminal device receives a data request instruction through the target channel, and obtains multimedia data corresponding to the first sub-description information of the target description information.

[0121] Step S521: The second terminal device sends multimedia data corresponding to the first sub-description information through a target channel.

[0122] Step S522: The first terminal device obtains the multimedia data corresponding to the first sub-description information through the target channel, and displays the multimedia data corresponding to the first sub-description information.

[0123] In addition, it should be pointed out that changes to at least part of the target multimedia data in the second terminal device, such as deletion, addition or modification, can be displayed in real time in the first terminal device. For example, after the second terminal device detects an adjustment operation on the target multimedia data (such as deletion, addition or modification), and when it is determined that it is in a multimedia sharing state, it will scan the adjusted target multimedia data, and then synchronize the target description information of the adjusted target multimedia data (also referred to as adjusted target description information) to the first terminal device, so that the first terminal device can display the latest target description information in real time.

[0124] Furthermore, the first terminal device or the second terminal device may also actively end the multimedia sharing state, for example, by clicking a specific button to end the multimedia sharing state.

[0125] In summary, this technical solution has the following beneficial effects:

[0126] First, in the disclosed solution, users do not need to select the files to be shared each time they share. They only need to confirm whether to share when establishing a cross-device connection. The operation is simple, thus effectively improving the user experience.

[0127] Second, in the disclosed solution, there is no need to occupy extra local storage space, thus further improving the user experience.

[0128] Third, in the disclosed solution, the file system of the MediaProvider component can be used in the first terminal device to implement a user-state file system. For example, the complete content of any shared multimedia data can be viewed in real time in response to the user's file reading and other operation requests. For example, in a scenario where the first terminal device displays a shared thumbnail, if it is necessary to further view the complete content of a picture in the thumbnail, the complete data of the picture to be viewed can be transmitted across devices, that is, only a small amount of data needs to be transmitted to meet the user's need to view the complete content. Compared with existing solutions, the disclosed solution reduces the time overhead of data transmission and further improves the user experience. Moreover, the above process does not require tedious operations by the user.
