An exemplary embodiment of the present disclosure provides an architecture of a cloud gaming system. As shown in fig. 1, the cloud gaming system 100 may include: terminal devices 101, 102, 103, 104, and a cloud server 105. The terminal devices 101, 102, 103, 104 execute the functions of the game client, and in the cloud game environment, the terminal devices 101, 102, 103, 104 need to have a display to play the game screen and basic processing and storage functions. Fig. 1 shows four different types of terminal devices, where the terminal devices include smart devices with web browsers, such as smart phones, tablet computers, Personal Computers (PCs), smart televisions, game consoles, and the like, and the disclosure is not limited to a specific type of terminal. The cloud server 105 performs the functions of a game server, which is generally a server cluster, and fig. 1 shows that the cloud server 105 may include an instruction server 1051, a game server 1052, and a streaming server 1053, and the functions of the servers are described in detail below; server components with other functions can be added to the cloud server 105, or servers with different functions can be deployed on the same device; the present disclosure is not limited to a specific architecture of cloud server 105. The interaction of game data is performed between the terminal devices 101, 102, 103, 104 and the cloud server 105 through a network.
Exemplary embodiments of the present disclosure provide a cloud game processing method, which may be performed by the cloud server 105 or the terminal devices 101, 102, 103, and 104 described above. Taking the terminal device 101 (i.e. a smartphone) as an example, the method and the process are specifically described from two aspects of the cloud server 105 and the terminal device 101, respectively, and the method and the process are the same as the principle for other types of terminal devices 102, 103, and 104.
In the present exemplary embodiment, the terminal apparatus 101 may display a cloud game interface through a web browser. Specifically, the game can be played without installing a client program of the cloud game on the terminal device 101, inputting a website of the cloud game through a web browser, and entering a cloud game interface.
Fig. 2 shows a flow of a cloud game processing method performed by the cloud server 105, which may include the following steps S210 to S240:
step S210, receiving a game request sent by the terminal device.
The game request is generated by the terminal device 101 in a cloud game interface displayed by a web browser. For example: when the network browser enters the cloud game interface, a game request can be triggered to be generated, or a user performs related operations for starting a game in the cloud game interface, such as logging in a game account, selecting a certain type of cloud game, clicking an option for starting the game, and the like, so that the game request can be triggered to be generated. The web browser may determine address information of an object of the game request, i.e., the cloud server 105, through a domain name of the cloud game interface.
In the present exemplary embodiment, since the terminal apparatus 101 does not have a client program installed, data transmission and reception between it and the cloud server 105 is realized by a web browser. After the game request is generated, the request is sent to the cloud server 105 through the web browser. After receiving the game request, the cloud server 105 parses the content in the request, and may check the game request, for example, check a game account number and a password, check security (e.g., whether the device is a device that logs in frequently), check whether the web browser meets the game requirement (e.g., whether the device has a relevant video playing plug-in), and establish a session with the web browser of the terminal device 101 after the check is passed.
A session between the terminal device 101 and the cloud server 105 may adopt a WebRTC (Web Real-time communication) Protocol, which performs data transmission by using a UDP (User Datagram Protocol) mode, and has better Real-time performance compared with a TCP (transmission control Protocol) mode commonly used between a client and a server, and is more suitable for an application scenario of a cloud game.
The game request comprises game video parameters requested by a user or screen display parameters and decoding performance parameters of the terminal device 101. The game video parameters refer to video parameter information meeting the playing requirement of the terminal device 101, and may include a format, a size, a resolution, a code rate, a frame rate, and the like of a video, and if the game video parameters are not determined in advance, the cloud server may send an inappropriate game video to the terminal device 101, which affects the game experience of the user on the terminal device 101. The screen display parameters can be the size, resolution and other parameters of the current screen display of the network browser detection device. The decoding performance parameters may include the processor performance of the terminal device 101, the maximum decoding rate of the decoder in the web browser, and the like.
Step S220, determining game video parameters according to the game request.
The game video parameters comprise resolution parameters or code rate parameters. The resolution parameter needs to correspond to the screen display parameter of the terminal device 101 to meet the playing requirement of the terminal device 101. The bitrate parameter is a measure of the compression ratio when the game video is encoded, and the higher the bitrate parameter is, the smaller the compression ratio is, the higher the picture quality is, and of course, the higher the decoding performance requirement on the terminal device 101 is. Therefore, the cloud server 105 may determine an appropriate resolution parameter according to the screen display parameter of the terminal device 101, and determine an appropriate code rate parameter according to the decoding performance parameter of the terminal device 101.
Or the game request includes the game video parameters requested by the user, for example, the corresponding game video parameters are set by the user when playing the game, the cloud server 105 may directly extract the game video parameters.
In an alternative embodiment, the game request may include an identifier of the terminal device 101, for example, a computer name, an IMEI (International Mobile Equipment Identity), a MAC address (Media Access Control), and the like, for indicating the Identity of the terminal device 101. In addition, the game request may also include basic information parameters of the terminal device 101 or the web browser, such as a mobile phone model, a screen size, a screen resolution, a name, a version, a plug-in, and the like of the web browser, and the web browser may detect these parameters in general, or may record related information in the user data and directly obtain the related information.
For terminal devices which are accessed for many times for a long time and have a stable network state, the cloud server 105 may directly determine game video parameters according to the identifier of the terminal device 101, for example, analyze the model of the mobile phone according to the identifier of the terminal device 101, determine the screen size and resolution of the mobile phone, and further determine corresponding game video parameters.
In an alternative embodiment, the cloud server 105 may also record information of the identification of the terminal device 101 and its game video parameters. Specifically, when the terminal device 101 enters the cloud game interface through the web browser, a game request is generated; the game request may include an identification of the terminal device 101 and screen display parameters; then, the terminal device 101 sends the game request to the cloud server 105; when receiving a game request sent by the terminal device 101, the cloud server 105 acquires an identifier and a screen display parameter of the terminal device 101 in the game request; and generating game video parameters according to the screen display parameters of the terminal equipment 101, and establishing a mapping relation between the identifier of the terminal equipment 101 and the game video parameters so as to be used for determining the game video parameters according to the identifier of the terminal equipment 101.
When the game request is sent, the cloud server 105 does not record information about the terminal device 101, and the game request can be regarded as a process of calibrating game video parameters, and the cloud server 105 determines the game video parameters according to the screen display parameters, forms a mapping relation with the identifiers of the terminal devices, and records the mapping relation in the configuration table. When the terminal device 101 sends the game request again, the cloud server 105 may find the game video parameter corresponding to the device identifier by querying the configuration table.
Further, the game request may further include a decoding performance parameter of the terminal device 101; the decoding performance parameters may include the processor performance of the terminal device 101, the maximum decoding rate of the decoder in the web browser, and the like. When generating the game video parameters, the cloud server 105 determines the code rate parameters according to the decoding performance parameters of the terminal device 101. The game video parameters include a code rate parameter, so that the cloud server 105 subsequently processes the game video by using the code rate parameter to obtain code stream data suitable for the decoding performance of the terminal device 101.
The above-described game video parameters are determined according to the screen display parameters and decoding performance parameters contained therein when the terminal apparatus 101 transmits a game request. However, the screen display parameters and decoding performance parameters of the terminal device 101 are not the same, for example, the display resolution is adjusted, the web browser is updated, a new decoding plug-in is replaced, and the like. Therefore, when a preset condition is met, for example, every certain period (for example, one week, one month, etc.), or the web browser detects that the screen display parameter or the decoding performance parameter changes, in this case, if a cloud game interface is logged in, the terminal device 101 may send a game request including the latest screen display parameter and decoding performance parameter of the terminal device 101 to the cloud server 105; the cloud server 105 may update the game video parameters according to the latest screen display parameters and decoding performance parameters. Thereby adapting to the changes of the terminal equipment 101 and meeting the requirements.
And step S230, receiving a game operation instruction sent by the terminal equipment, and generating a game video according to the game operation instruction and the game video parameters.
The user can input game operation instructions of the cloud game in the cloud game interface. The terminal device 101 sends a game operation instruction through the established session, and after receiving the game operation instruction, the cloud server 105 executes the game operation instruction in the game program to push the game progress to obtain a corresponding game video. For example, if the game operation instruction input by the user is to release the skill, the cloud server 105 may generate a game animation in which the skill is released. The generated game video should conform to the game video parameters of the terminal device 101.
Step S240, sending the game video to the terminal device, so that the terminal device displays the game video through the web browser.
In general, after generating a game video, the cloud server 105 may convert the game video into code stream data, for example, encode the game video according to H264 (a standard format for video encoding), generate corresponding code stream data, and transmit the corresponding code stream data to the terminal device 101.
After receiving the code stream data, the terminal device 101 may decode the data by using a video player built in the web browser, and play the decoded game video.
The cloud server 105 and the terminal device 101 can adopt a WebRTC protocol to transmit game videos, so that the real-time performance is better, and the method is more suitable for application scenes of cloud games.
In practical applications, the steps S230 and S240 are two steps executed in a loop. After seeing the game video, the user can input a new game operation instruction and send the new game operation instruction to the cloud server 105; the cloud server 105 generates a new game video by executing the game operation instruction, encodes the new game video into code stream data, and sends the code stream data back to the terminal device 101; the terminal device 101 further analyzes the corresponding game video, so that the user inputs the game operation instruction of the next stage therein. Thereby facilitating game play.
In an optional implementation manner, the cloud server 105 may monitor network performance parameters of the terminal device 101, such as a network transmission rate, a bandwidth, a ratio occupied by other programs, and the like, to reflect a current network transmission condition between the terminal device 101 and the cloud server 105, and perform corresponding adjustment on the code stream data according to the network transmission condition, for example, when the network transmission condition is good, the code rate, the frame rate, and the like may be increased, and otherwise, the code rate, the frame rate, and the like may be decreased.
In an optional implementation manner, when the terminal device 101 receives the game video sent by the cloud server 105, the game video may be placed in a buffer of the web browser, and the game video may be read from the buffer and displayed. Under the condition of setting the buffer area, when data transmission is interrupted for a short time (such as a short-time network interruption), the terminal device 101 can continue to decode and play the video frames in the buffer area so as to maintain normal playing of pictures within a period of time, and to a certain extent, the problems of blockage, black screen and the like are solved.
In the above embodiment, setting the buffer may increase the delay of the game screen, i.e., the time difference between the cloud server 105 transmitting the game screen and the terminal device 101 displaying the game screen. Generally, the larger the buffer size, the more severe the delay. The buffer size may be adjusted by:
sending a data packet of the game video to the terminal equipment, and recording the sending time;
receiving a game operation instruction which is sent by the terminal equipment and corresponds to the data packet, and recording the receiving time;
acquiring network time delay according to the difference value of the receiving time and the sending time;
and sending the network delay to the terminal equipment, so that the terminal equipment adjusts the size of the buffer area of the network browser according to the network delay.
As illustrated in connection with fig. 3, the cloud server 105 sends a data packet x of the game video and a timestamp t thereof to the terminal device 101; the user inputs a game operation command c in the game screen corresponding to x, the timestamp of the game operation command c is also set as t, and the terminal device 101 sends the game operation command c and the timestamp t to the cloud server 105; the cloud server 105 receives the game operation instruction c and the timestamp t thereof, compares the game operation instruction c with the current time t + Δ t, and calculates a time difference value Δ t, namely network delay. The cloud server 105 sends the network delay to the terminal device 101, and the terminal device 101 adjusts the size of the buffer according to the size of the network delay. For example, if the difference Δ t is within a normal numerical range, the current delay is considered to be acceptable, the capacity of the buffer area does not need to be adjusted, or the buffer area is considered to have a pressure-bearing space, so that the capacity of the buffer area can be properly increased; if the difference Δ t is out of range, the current delay is considered unacceptable and the buffer size needs to be adjusted, typically by reducing the size.
Further, the cloud server 105 may determine whether the network delay is greater than a first threshold, and if so, down-regulate a game video parameter, such as a resolution parameter, a bitrate parameter, and a frame rate parameter, for example, one or more of the resolution parameter, the bitrate parameter, and the frame rate parameter may be reduced to improve the network delay. The first threshold is a preset parameter and is used for measuring the condition of network delay, and if the network delay is greater than the first threshold, which indicates that the network condition is poor, the frame rate of the game video can be reduced, which is equivalent to reducing the data volume of the game video in unit time, so as to improve the fluency of running the cloud game on the terminal device 101.
As described above with reference to fig. 1, the cloud server 105 may include an instruction server 1051, a game server 1052, and a streaming server 1053, splitting the functions of the cloud server 105. The method comprises the following specific steps:
the instruction server 1051 may be configured to receive a game operation instruction sent by the terminal device 101, and forward the game operation instruction to the game server 1052. The method is mainly responsible for analyzing and forwarding the game operation instruction, the analyzing may include analyzing the game operation instruction of the terminal device 101 into a signal recognizable by the server, and the forwarding may include determining an appropriate game server 1052 to send the game operation instruction as a target.
The game server 1052 may be configured to generate a game video by executing the game operation instruction, and transmit the game video to the streaming server 1053. Which is primarily responsible for the processing of the game logic, the game engine typically runs on the game server 1052.
The streaming media server 1053 may be configured to process the game video according to the game video parameter, and send the processed game video to the terminal device. It is mainly responsible for format processing, encoding and transmission of video.
Further, the server components can achieve regional distributed deployment, for example, the instruction server 1051, the game server 1052 and the streaming media server 1053 are deployed in different regions respectively, so that game requests and game operation instructions can be processed nearby, and efficiency is high. The terminal apparatus 101 may perform DNS (Domain Name System) resolution in advance to determine a line; when the network browser opens the cloud game interface, the speed can be automatically measured and the optimal line can be selected (namely, a proper server is selected); during the game of the user, the line state can be detected at regular intervals, and the line can be dynamically adjusted based on the network condition.
Fig. 4 shows a flow of a cloud game processing method performed by the terminal device 101, which may include the following steps S410 to S450:
and step S410, displaying a cloud game interface through a network browser.
Specifically, the user opens the web browser, inputs the related website of the cloud game, and then can enter the cloud game interface.
Step S420, a game request is generated according to the input of the user to the cloud game interface.
The game request is used for determining game video parameters, and may include game video parameters requested by a user or screen display parameters and decoding performance parameters of the terminal device 101; the game video parameters include a resolution parameter or a code rate parameter.
Generally, a user performs operations related to starting a game in a cloud game interface, such as logging in a game account, clicking an option for starting the game, and the like, and may trigger generation of a game request.
And step S430, sending a game request to the cloud server, and enabling the cloud server to return the game video according to the game video parameters.
The web browser may determine address information of an object of the game request, i.e., the cloud server 105, through a domain name of the cloud game interface. Cloud server 105 may parse the information contained in the game request to determine the corresponding game video parameters. Furthermore, the user can input a game operation instruction of the cloud game in the cloud game interface, the terminal device 101 sends the game operation instruction to the cloud server 105, and the cloud server 105 executes the game operation instruction in the game program to push the game progress to obtain a corresponding game video. For example, if the game operation instruction input by the user is to release the skill, the cloud server 105 may generate a game animation with the released skill, and generate a corresponding game video according to the game video parameters to return to the terminal device 101.
In an alternative embodiment, the cloud server 105 may check the game request, for example, check a game account number and a password, check security (for example, whether the device is a device that logs on frequently), check whether the web browser meets the game requirement (for example, whether the device has a related video playing plug-in), and perform the above process of generating and returning the game video after the check is passed.
Step S440, receiving the game video and displaying the game video through the web browser.
Generally, the game video sent by the cloud server 105 is code stream data subjected to encoding and compression, and after receiving the code stream data, the terminal device 101 may use a video player built in a web browser to decode and play the decoded game video.
When the terminal device 101 receives the game video transmitted by the cloud server 105, the game video may be placed in a buffer of the web browser, and the game video may be read from the buffer and displayed. In an alternative embodiment, the Game request may include a Game type, such as which type the cloud Game belongs to, for example, FPS (First-Person Shooting), MOBA (Multiplayer Online team sports), MMORPG (Massive Multiplayer Online Role Playing), turn Game, and the like. And further, the size of the buffer area of the web browser can be set according to the game type. Generally, the requirement of the FPS game on instantaneity is high, and the tolerable delay is low, so that a small buffer area can be arranged to reduce the delay of game picture display; the requirement of the MOBA game, the MMORPG game and the turn game on the instantaneity is decreased, and the corresponding buffer area size can be increased. Of course, the specific value of the buffer size also needs to be determined according to the actual application requirements, which is not limited by the present disclosure.
The buffer size set as described above is generally the initial size. Further, during the game, along with the fluctuation of the network condition, the buffer size can be dynamically adjusted by the following method:
determining a second threshold value according to the game type;
receiving network delay sent by the cloud server, and judging whether the network delay is greater than a second threshold value;
if the judgment result is yes, the size of the buffer area of the network browser is adjusted downwards.
Wherein the second threshold is an upper limit value of tolerable delay determined according to the game type. If the network delay is greater than the second threshold, it indicates that the current delay is too high, and the buffer size may be adjusted downward to reduce the delay level, thereby ensuring that the network delay is within an acceptable range in real time.
In an optional implementation, the cloud game processing method may further include the steps of:
when the utilization rate of the buffer area is less than or equal to a third threshold value, caching the game video in the buffer area in a GOP mode;
when the utilization rate of the buffer area is greater than a third threshold value, determining a frame skipping parameter according to the utilization rate;
and performing frame skipping processing on the GOP of the game video according to the frame skipping parameters.
The third threshold is a preset threshold for measuring whether the usage rate of the buffer is too high, and may be, for example, 80%. When the utilization rate Of the buffer area is less than or equal to the third threshold value, the pressure Of the buffer area is small, and enough buffer space is available, and at this time, the game video is buffered in a Group Of Pictures (GOP), namely, the game video with the complete frame number is buffered. As the usage rate of the buffer increases, when the third threshold is exceeded, the buffer may not be able to carry more game videos, so a frame skipping strategy may be adopted, in the video data transmission in the cloud game, by appropriately discarding a part of the video reference frames, the frame number is sacrificed to satisfy the normal video playing, and the jam is prevented. Specifically, frame skipping parameters can be determined according to the utilization rate of the buffer area, wherein the frame skipping parameters include indexes such as a frame skipping ratio and the like, the frame skipping ratio refers to how many frames are skipped every other frame and how many frames are skipped, and generally, the higher the utilization rate of the buffer area is, the higher the frame skipping ratio is; when skipping frames, preferentially discarding part of reference frames until key frames remain; after the frame skipping is processed, the GOP is not cached any more, and the key frame of the GOP is cached instead; after a period of frame skipping processing, the buffer pressure may be relieved, the delay or stuck condition improved, and when the usage of the buffer is detected to have dropped below a third threshold level, the buffered GOP may be restored.
Two ways of improving the gaming experience are proposed above: adjusting the size of the buffer area, and performing frame skipping processing on the game video. In practice, two ways can be combined, for example: determining a second threshold value according to the game type, and adjusting the size of the buffer zone downwards when the network delay exceeds the second threshold value; within the second threshold, if it is desired to further reduce the network delay, the buffer may be further adjusted downward; however, lowering the buffer may cause the utilization rate of the buffer to increase, and when the utilization rate of the buffer is higher than a third threshold, discarding the reference frame and caching the key frame of the GOP, which is equivalent to sacrificing the video frame number to improve the network delay; if it is desired to improve the video picture quality, the GOP may be buffered in the buffer, and when the usage rate of the buffer is higher than the third threshold, the buffer size is appropriately adjusted up within the second threshold, which is equivalent to sacrificing network delay to improve the picture quality. Therefore, different user requirements can be met by combining the two modes flexibly.
