Description

Web browser-based Android application streaming service provision method and system therefor {METHOD AND SYSTEM FOR WEB BROWSER BASED ANDROID APPLICATION STREAMING SERVICE}

The present invention relates to a method and a system for providing an Android application streaming service using a web browser. More specifically, it relates to a system and method for transmitting an Android application installed on a server to a web browser, and for a user to run an Android application in a streaming method without installing any software or application.

The cloud game market is growing amid increasingly fierce competition. In the overseas market, global IT companies such as Google, Microsoft, Facebook, Nvidia, and Apple have entered the market. In the domestic market, mobile carriers have started cloud game business in a way that collaborates with foreign IT companies. According to market research firms, the global cloud game market is expected to grow more than 30 times from $160 million (about 190 billion won) in 2019 to $0.55 billion (about 61 trillion won) in 2023.

Users can enjoy streaming games after connecting to the cloud, and by installing a cloud service exclusive app, users can use it on mobile as well as Windows PC. The advantage of streaming games like this is that users can play high-end games that are difficult to run on their client devices or games of other platforms, and even if users' devices are in a state of being difficult to run the latest games due to low specifications Console, PC, and mobile games can be played.

However, despite these advantages, problems in using cloud game services are constantly being raised. The downside of cloud streaming games is that they are streaming high-end games based on PC and console games, so the streaming is interrupted due to latency, resulting in serious degradation of user experience. In addition, high-spec server instance costs and network traffic costs are incurred, so users are charged a high usage fee. And all cloud games can only be used by installing a dedicated app or software from each service provider.

More specifically, the problems of conventional services are as follows.

App player

The app player is a program that allows you to run applications on your smartphone on your PC. It is generally used to enjoy mobile games on the big screen of a PC. The number of users is increasing in that it is difficult to run the latest games due to lack of device specifications, or because they can relieve the burden of battery capacity problems and heat generation because they play games on mobile for a long time. In addition, as the scale of games increases as well as high specifications, the use of app players that can be used regardless of the performance of smartphones or PCs is increasing. However, when playing Android games as an app player, a program installation and a game application installation are required, and a problem has been pointed out that the game does not run properly or the app player program performance is unstable.

Cloud games

The advantage of cloud games is that users can play high-end games that are difficult to run on their client devices or games of other platforms, and users' devices have low specifications, so even though it is difficult to run the latest games, the streaming method provides high-end consoles, PC and mobile games can be played. On the other hand, the disadvantage of cloud games is that there may be interruptions or breaks in streaming due to high latency. Since it must be played in real time, all screens and sounds of the game must be transmitted to the user's device in real time. If the game is interrupted while the user is playing the game in real time, the user experience is severely deteriorated due to the nature of the game. In addition, high-spec server costs and network traffic costs are incurred in order to operate streaming games, which is a big disadvantage to attracting users who have low purchasing power or want to use free use, as the usage fee is charged a lot. Is one of them. And all cloud games can only be used by installing a dedicated app or software from each service provider.

HTML5 games

In order to play the existing game, it was necessary to install it on the platform or read the external medium in which the game was stored, and there were also restrictions between platforms in running the game. However, HTML5 based games have features that are not bound by these restrictions. HTML, which means'hypertext markup language', is a markup language that plays a dominant role in composing web pages. Initially, it only consisted of configuring web pages, but as the version was gradually upgraded, various additional functions such as video and audio and the latest multimedia contents were developed to make it easy to view in a browser without ActiveX or plug-ins. The latest version, HTML5, was prepared by the W3C, an international web standards consortium on October 28, 2014, and has been updated since then, with the 5.2 recommendation being released on December 14, 2017. HTML5 games have the disadvantage of slow real-time response, so they are not suitable for fighting games in which seconds are fought. Also, mobile games cannot be played because mobile games are not released as HTML5 games.

Accordingly, there is a need for a new method of providing a web browser-based streaming application that can overcome the drawbacks of the conventional cloud type streaming game and other types of app provision methods.

For example, when a user selects a desired app by running a web browser on a smartphone, which is the user terminal 100, and requests execution of the app, the app streaming server 200 uses the emulator 210 configured to run the selected app. After running the app through the app, the video and sound of the app are transmitted through the web browser of the user terminal 100, and the video and sound of the executed app are played back in the user terminal 100 without downloading or installing the app. You can use the running app like an app running on your own device.

Here, the provided app may be an Android OS-based application, and may include various types of apps such as games, shopping, or public institution apps.

3 is a flowchart illustrating a method of providing a web browser-based Android application streaming service according to an embodiment of the present invention.

First, the service provider pre-installs a plurality of emulators for executing a plurality of apps provided to the user in the app streaming server 200 (S301).

The user may execute a web browser through the user terminal 100 (S302), wherein the web browser may include various forms such as Internet Explorer, Chrome, Apple's Safari, and Firefox. When the user terminal 100 accesses a website address for providing an app, a list of available apps is displayed (S303), and the user can select an app to run or experience from the list of apps through the user terminal 100. (S304)

The app selection information selected by the user terminal 100 is transmitted to the app streaming server 200, and the emulator 210 for the selected app may be executed by the app streaming server 200 (S306). In addition, the app streaming server The image and sound of the app executed by the emulator 210 of 200 may be transmitted to the user terminal 100 by streaming. (S307) At this time, data usage is lowered and transmitted by a streaming compression delivery method, and hardware acceleration The delay rate can be minimized by streaming. Here, each of the plurality of emulators 210 may correspond to a web browser of each user terminal 100 and may be configured to execute an app selected by the user through the corresponding web browser.

In addition, the user may perform user manipulation, such as inputting an app-related button, through the user terminal 100 (S308). At this time, the event information related to the user manipulation is transmitted to the app streaming server 200 in real time (S309), The app image and sound reflecting the user manipulation by the emulator 210 may be transmitted to the user terminal 100 in real time. For example, users' events (operations) can be transmitted in real time and customized key mapping can be provided. Bare-metal through Intel's VT virtualization technology and Linux's kernel-based virtualization (KVM) ) Level of virtualization, and by configuring the Graphics Pipeline optimized for Android, the open graphics library OpenGL ES 3.x and Vulkan API can be supported in line with next-generation games.

4 is a flowchart illustrating a specific method performed between a web browser and an emulator to provide a web browser-based Android application streaming service according to an embodiment of the present invention.

The emulator 210 running in the app streaming server 200 can execute and wait for a web socket server. (S401) A web socket is a two-way for communication between a web server and a web browser. As one of the communication standards, it is a communication protocol that enables full-duplex communication between a web browser and a web server.

In the user terminal 100, the user accesses the app providing website through the web browser 110, selects an app to be executed, and clicks an app execution button (S402). When a server is requested, the load applied to the server can be distributed through a load balancer, and server information can be transmitted to the web browser 110 by returning one of the available servers.

The web browser 110 may connect to an available server and transmit app information (S403). In response to this, the emulator 210 may perform a web socket connection and execute the app. (S404) In addition, the emulator 210 may transmit a web socket connection success signal to the web browser 110 (S405), and receive screen encoder setting information to be applied to the emulator 210 from the web browser 110 (S406) Here, the web Since the app streaming server 200 can determine whether the web browser 110 of the user terminal 100 supports WebRTC only when a connection is first made through a socket connection, the web between the web browser 110 and the emulator 210 The socket connection precedes the connection, and the web browser 110 and the emulator 210 may be connected using various communication protocols even if the connection is not a web socket connection.

Next, when it is determined that the web browser 110 is a browser that supports WebRTC, a WebRTC use request may be transmitted to the emulator 210. Here, WebRTC (Web Real-Time Communication) is a 　API designed to communicate with each other without the help of a plug-in 　 between web browsers 　, and as an open framework for the web that enables real-time communication capabilities within the browser, voice calls, video calls , P2P file sharing, etc.

Referring to FIG. 4, when the web browser 110 is a browser supporting WebRTC, a request to use WebRTC is requested from the emulator 210, and when using WebRTC, the emulator 210 provides a data channel and a local offer. Generates and transmits an offer to the web browser 110 through a web socket, receives an offer from the web browser 110, registers a remote offer, creates a local answer, and performs an answer through a web socket. When transmitted to the emulator 210, the emulator 210 can register a remote answer. (S407a, S407b) In this way, WebRTC clients must exchange and check media information such as resolution and codec function with each other. Signaling for the exchange is carried out through 　Offers and 　Answers using the Session Description Protocol (SDP). According to the present invention, the emulator 210, which is a software that emulates the virtualized OS in the app streaming server 200, operates a web socket server, and treats one of the P2P (peer-to-peer) communication used for WebRTC as a server. And run it.

On the other hand, when the web browser 110 does not support WebRTC, it may be determined whether it supports Media Source Extensions (MSE), and when it does not support MSE, it may be determined whether or not WebAssembly (web assembly) is supported. . In this case, when the web browser 110 does not support MSE and supports WebAssembly, it is possible to load WebAssembly and execute a WebWorker (webworker) decoder (S408).

Next, the frame buffer may be hardware encoded in the emulator 210 (S409). In this case, when using WebRTC, the frame buffer may be transmitted to the web browser 110 through the data channel (S410a), and WebRTC is used. If not, the frame buffer may be transmitted to the web browser 110 through the web socket (S410b).

Next, when the web browser 110 supports MSE and does not support WebAssembly, a frame buffer may be added to the video through the MSE (S411a). On the other hand, when not supporting MSE and supporting WebAssembly, WebWorker The frame information may be transmitted to the decoder (S411b). At this time, the decoded frame may be hardware accelerated using WebGL to perform drawing on the canvas.

Finally, when the app is terminated, both the web browser 110 and the emulator 210 may release the web socket and WebRTC connection (S412).

The present invention is capable of providing a user environment in which an application to be used by the user can be executed directly without downloading the application by accessing a web site address from a web browser in an Internet-enabled environment, and various web browsers are supported. Do.

5A and 5B are exemplary diagrams for explaining a user screen for a web browser-based Android application streaming service service according to an embodiment of the present invention.

Referring to FIG. 5A, a list of apps that can be executed by the user is displayed through the web browser 110 of the user terminal 100, and a button for immediately executing an app selected by the user can be displayed together. The differentiated part is that it is possible to provide a function (We App Play) to experience the app without downloading to the user terminal 100. When the user presses the app execution button, a virtual mobile screen is displayed without installing any software on the user terminal 100, and the actual operation of the corresponding app may be shown there. In addition, it is also equipped with functions that allow users to directly operate the app, not just showing the screen of the app, and if you like it after experiencing the game app, you can download the app by clicking the download button next to it.

For example, a game app provided on a website may be accessed with a basic ID previously created by a service provider, and may be configured to allow game play to proceed from a specific point in time. For example, in existing mobile games, after downloading the patch file from the App Store, download the patch file once more, create your account, and start with a tutorial in which the game is explained, but the games provided according to the system according to the present invention are all the above procedures. After passing over, it is possible to experience through an account prepared in advance at a point that can give the user the most impact. That is, the emulator 210 executes a specific point in time of the game application selected in the user terminal and encodes the image and sound, so that the user terminal 110 can play the game from a specific point in time. Can be maximized.

In addition, referring to FIG. 5B, it can be seen that the game app selected by the user is displayed and executed on the screen through the web browser 110 of the user terminal 100. The web browser 110 of the user terminal 100 transmits information on user manipulation to the app streaming server 200, and the video and sound reflecting the manipulation of the actual application from the server 200 where the app is installed and executed are displayed in real time. It may be transmitted to the web browser 110.
