The Internet of things mainly solves the interconnection among articles (thining to thining, T2T), people (Human to thining, H2T) and people (Human to Human, H2H).
2) Soft bus
The soft bus and the computer system bus hardware bus, hard bus for short, play the same role in the computer system, and the soft bus, like the hard bus, plays a role of connecting a bridge for transmitting information. Unlike a hard bus, which transfers information via a fixed number of lines and 0, 1 signals, a soft bus is a set of programs that establishes connections between processes, software functions, via buffers.
3) Fast application
The fast application is a new form application which does not need to be installed, can be developed by using a front-end technology stack, has the double advantages of an HTML (Hypertext Markup Language) page and a native application, and has the performance experience of the native application without installation, namely point-and-play. By deeply integrating the fast application framework into mobile phone systems of various manufacturers, seamless connection between user requirements and application services can be realized on the operating system level, and the use experience of users and the conversion efficiency of the application services are improved.
Illustratively, the fast application includes a number of functional modules including, but not limited to, basic functions, network access, file data, and the like. Each functional module includes a plurality of sub-functional modules.
Fig. 1 is a block diagram illustrating a fast application according to an exemplary embodiment, and as shown in fig. 1, a block 100 of the fast application includes: a scenario portal 120, a fast application engine 140, and Operating System (OS) infrastructure & hardware 160.
Optionally, the scene portal 120 may be at least one of a negative one-screen, a global search, a lock screen, a desktop, an application marketplace, a browser, and a two-dimensional code. The appearance of the scene portal 120 may be in the form of a page or a card.
The fast application engine 140 includes a front-end framework 141, a general scenario 142, a lightweight scenario 143, an embedded SDK (Software Development Kit) 144, and a business access 145. The front-end framework 141 includes a Model-View-Model (MVVM), a V-DOM, a router, an Application Programming Interface (API), a service API, a User Interface (UI) component, and the like. The general scene 142 and the lightweight scene 143 include a JavaScript engine, a standard rendering engine, an extreme rendering engine, an end-cloud-core acceleration, a security mechanism, an emerging scene AI (Artificial Intelligence), an AR (Augmented Reality), and the like, and system integration (application management, rights management, and the like). Service access 145 includes Push (Push), account/payment, etc. OS infrastructure & hardware 160 includes: graphics libraries, native controls, system services, and GPUs (Graphics Processing units)/NPUs (Neural-network Processing units), among others.
For example, from the execution path level, there are a standard HTML5 manner to support a general Web scene (generally through a Webview component of the system or a customized Webview) and a js (javascript) + Native manner to support a lighter-weight and faster experience.
FIG. 2 is a flow diagram illustrating the start-up of a fast application, as shown in FIG. 2, according to an example embodiment
1) When the fast application is started for the first time, a user triggers downloading of a program package of the fast application through click operation, and meanwhile, an engine of the fast application carries out initialization related work. When the complete downloading of the program package of the fast application is completed and the verification of the program package is completed, the JavaScript file of the first page that needs to be displayed by the fast application starts to be loaded and starts to be rendered. The program package downloading in the process is a bottleneck, and from the measured data in the previous period, the package downloading time of about 200K under the normal network is at least more than 400 milliseconds, and the 2M package is more than 2 seconds.
2) The page rendering comprises JavaScript loading, execution of page and JavaScript frame logic, layout operation and drawing of the native UI control. When the logic in the page is executed, one or more network requests (from the page to the application-own three-party server) are generated, and the data returned by the network requests drive the re-rendering of the page until the content of the first screen is completely displayed.
Here, the network request, JavaScript execution, typesetting and drawing are not simply in a serial relationship, but are parallelly interleaved to influence the rendering performance of the whole page, and are strongly related to the logic of page design, the network condition and the running state of the device.
Due to the specificity of fast applications, fast applications are expected to perform more tasks and perform more functions. At present, while the function of the fast application is being gradually improved, the embodiment of the present disclosure provides a new function of the fast application, and the new function is utilized to implement automatic discovery of devices in the soft bus, and execute related services based on the discovered devices, thereby expanding the function of the fast application and improving the processing capability and the practicability of the fast application.

Fig. 5 is a flowchart illustrating a device discovery method according to another exemplary embodiment, where the device discovery method may be applied to a system including at least two devices, where the at least two devices are respectively connected to a soft bus, so that mutual discovery may be performed between the devices in the system, for example, the system may be the system illustrated in fig. 3, the device may be the device 310 illustrated in fig. 3, and the soft bus may be the soft bus 320 illustrated in fig. 3, and the device discovery method is performed by a first device. As shown in fig. 5, the device discovery method may include the steps of:
step 501, a first device obtains service information of a second device of the at least two devices, the service information being issued to the soft bus by the second device.
In the embodiment of the present disclosure, the service information at least includes device information, and the device information is basic information of a device that includes the service information, for example, the device information may be identity identification Information (ID) of the device, a Name (Name) of the device, Description information (Description) of the device, type information (Category) of the device, Version information (Version) of the device, and the like.
Optionally, the service information of the second device further includes at least one of a file address of the multimedia file included in the second device and an encoding format of the multimedia file included in the second device.
The multimedia file can be any one type of video file, picture file or sound file, and the content in the file needs to be encoded in the transmission process of the multimedia file, wherein the encoding is to encode characters, numbers or other objects into digital codes by a preset method, or to convert information and data into a specified electric pulse signal.
Optionally, the first device receives service information of the second device, which is periodically broadcasted in the soft bus by the second device.
The device distributes the service information of the device to the soft bus in a periodic broadcast mode, and the service information can be acquired by other devices.
Optionally, the first device periodically issues service information of the first device to the soft bus.
The first device may also issue its own service information to the soft bus in the same periodic broadcast manner as the second device, so as to be used by devices other than its own device for acquisition.
For example, when two devices, namely a television and a sound box, exist in one system, and the two devices are connected in the same wireless network, the two devices periodically issue service information of the respective devices to the wireless network, and when the television in the system is determined to be the first device, the television acquires the service information in the wireless network, and at this time, the television can acquire the service information issued by the sound box to the wireless network.
Step 502, the first device parses the service information of the second device to obtain the device information of the second device.
In the embodiment of the present disclosure, the service information of each second device, which is acquired by the first device through the wireless network, may be obtained by analyzing each service information, where the device information may be provided to the first device for the basic information of the second device corresponding to the service information.
For example, when three devices, namely a camera, a television and a microphone, exist in a system and are all connected in the same wireless network, when the television is used as a first device, two service information issued by two second devices can be acquired, the television analyzes the two acquired service information, and corresponding device information in the two service information can be acquired, wherein one device information includes a device name called a microphone, and the device is described as basic information such as a sound acquisition device; the other device information includes basic information such as a device name of a camera, a device description of an image acquisition device, and the like.
Step 503, the first device determines the second device as the discovered device in the soft bus according to the device information of the second device.
Optionally, when the service information of the second device further includes an encoding format of a multimedia file included in the second device, and when the encoding format is an encoding format supported by the first device, the first device determines, according to the device information of the second device, the second device as a discovered device in the soft bus.
Common encoding formats include ASCII (American Standard Code for information exchange Code), ANSI (American National Standards Institute), GBK (Chinese Internal Code Specification), Unicode (uniform Code), and the like.
The method includes that encoding formats supported by different types of devices may not be the same, so that when a first device receives service information issued by a second device and has an encoding format of a multimedia file, the first device may query the encoding format supported by the self device and compare the encoding format with the received encoding format one by one, and if the first device detects that the received encoding format exists in the self device, the second device corresponding to the service information including the encoding format may be determined to be a discovered device of the first device in a soft bus; if the first device does not detect that the received coding format exists in the device itself, it may be determined that the second device corresponding to the service information including the coding format is a device that is automatically ignored by the first device in the soft bus.
Optionally, the first device stores the service information issued by the second device determined as the discovered device in a memory of the first device, and may perform call parsing at any time.
For example, when three devices, i.e., a camera, a television and a microphone, exist in a system and the three devices are all connected in the same wireless network, when the television is used as a first device to acquire two types of service information issued by two second devices, the two types of service information both include encoding formats of multimedia files, the multimedia file generated by the camera is a video file, one encoding format for encoding the video file is adopted, the multimedia file generated by the microphone is a sound file, and the other encoding format for encoding the sound file is adopted. When the television serving as the first device analyzes the two service information to obtain the coding formats in the two service information, the television determines a multimedia file which can be decoded by the self device by comparing the coding formats supported by the self device, and if the coding formats are supported, the corresponding second device is determined to be found equipment of the television; and if the comparison shows that the television does not support the coding format, determining that the corresponding second equipment is the equipment ignored by the television. When the encoding format of the multimedia file generated by the camera is an encoding format supported by the television and the encoding format of the multimedia file generated by the microphone is an encoding format not supported by the television, the television can finally determine the camera as a found device and the microphone as an ignored device.
Optionally, an icon of the second device is displayed in the display interface of the first device.
The icon of the second device may be included in the service information issued by the second device, and specifically may be included in the device information in the service information.
Optionally, the second device corresponding to the icon displayed in the display interface of the first device may be the second device confirmed as the found device or the second device confirmed as the ignored device.
Optionally, the display interface of the first device may be a display interface of the first device system.
For example, fig. 6 is a schematic diagram of a device discovery interface in a system setup interface according to an embodiment of the present disclosure. As shown in fig. 6, when the first device is a mobile terminal and the user accesses the mobile terminal to the wireless network and opens the system setup interface of the mobile terminal, the other devices accessing the same wireless network, i.e., the second device, can be displayed on the interface of the mobile terminal. The displayed content includes icons and name information of the second devices, where the icons and the name information may be content in device information in service information issued by the second devices on the soft bus, and the icon information may also be content in device information in which the first device calls a corresponding picture in a picture template stored in a memory of the own device as an icon according to description information and type information in the device information of each second device, as shown in fig. 5, the devices of the same type may be displayed by the same type of icon, by comparing encoding formats in the acquired service information, if it is determined that the second device is a found device, the icons and the names of the second devices are displayed in an interface list of the first device, and if it is determined that the second device is a neglected device, the icons and the names of the second devices may be displayed in an interface list of the first device, but in an unselected state, the second device information display portion is shaded as in fig. 5; the icon and name of the second device may not be displayed in the interface list of the first device.
Optionally, an icon of the second device is presented in an application interface of a fast application running in the first device.
For example, fig. 7 is a schematic diagram of a device discovery interface in a fast application display interface according to an embodiment of the present disclosure. As shown in fig. 7, when the first device is a mobile terminal, and the user accesses the mobile terminal to the wireless network and opens the application center of the fast application of the mobile terminal, the application interface of the fast application center of the mobile terminal may display other devices, i.e., the second device, accessing the same wireless network. According to the result of comparing the coding format in the service information issued by the second device with the coding format supported by the first device, it is determined that a part of the second device is a discovered device and a part of the second device is an ignored device, and the icon and name information of the discovered device and the ignored device can be separately displayed on the application interface of the fast application.
Optionally, the display interface of the first device may also be an interface of a dedicated APP (Application).
Step 504, when the service information of the second device further includes a file address of a multimedia file included in the second device, the first device obtains the multimedia file from the second device through the soft bus according to the file address.
In the embodiment of the disclosure, when the second device contains the multimedia file, and the second device is confirmed by the first device as a discovered device, the first device may obtain a file address of the multimedia file in the second device by parsing the service information of the second device, and the first device obtains the multimedia file on the soft bus through the file address.
In the specific interface display of the first device, a user can select a found device to connect through a virtual control of a display interface, and the connected device can transmit a multimedia file.
In step 505, the first device plays the multimedia file.
In the embodiment of the present disclosure, the obtained multimedia file is decoded according to the encoding format of the second device obtained by the first device analyzing the service information of the second device, and the first device plays the decoded multimedia file.
Optionally, when the service information of the second device further includes an encoding format of a multimedia file included in the second device, the multimedia file is played according to the encoding format.
For example, the first device is a television, the second device determined as the discovered device by the television is a camera and a microphone, and when the user selects the camera and the microphone to be in a connected state in the display interface of the television, the video file acquired through the camera can be directly played in the display interface of the television, and the sound file acquired through the microphone can be directly played through a sound module of the television.
Optionally, the multimedia file may be directly played through a system function of the first device, or the multimedia file may be played through a fast application of a corresponding function of the fast application center, or the multimedia file may be played in a dedicated APP.
In the implementation of the application, a scheme for discovering devices in the soft bus and executing related services based on the discovered devices can be realized based on a fast application engine.
The fast application engine in the embodiment of the present application may include the following 3 layers.
