Description

Technical Field

[0001] The present invention relates to the field of network data transmission, and in particular to a game video transmission method and system based on a 5G network. Background Art

[0002] When users use smartphones or portable computers and other user terminals to play online games, the smoothness and stability of game video transmission directly affect the user's online gaming experience. In order to improve the efficiency of transmitting game videos to the user terminal, the user terminal can be connected to the 5G network, so that a 5G network channel is formed between the user terminal and the video data transmitter, which can maximize the transmission speed of the game video. However, in the actual game video transmission process, the data transmission performance of the video data transmitter itself will also affect the transmission quality of the game video. In the existing game video transmission operation, the video data transmitter currently connected to the user terminal cannot be changed. When the game video transmission is slow on the user terminal, the transmission source of the game video cannot be changed in time, and the smoothness and stability of the game video transmission cannot be effectively improved.

[0057] See also Figure 1 As shown, a game video transmission method based on a 5G network provided in an embodiment of the present application includes:

[0058] Based on the game video acquisition request of the user terminal, determine the game video attribute information that the user terminal expects to obtain; based on the game video attribute information, determine all video data senders matching the user terminal from the 5G network;

[0059] Based on the respective video data sending states of all video data sending terminals, all target video data sending terminals that can send the corresponding game video to the user terminal are determined from all video data sending terminals; based on the network locations of the user terminal and all target video data sending terminals in the 5G network, one target video data sending terminal is selected to establish a communication channel with the user terminal, so as to transmit the game video to the user terminal;

[0061] The beneficial effects of the above embodiments are as follows: the game video transmission method based on the 5G network determines all video data senders matching the user terminal from the 5G network based on the game video attribute information that the user terminal expects to obtain, and determines all target video data senders that can send corresponding game videos to the user terminal based on the respective video data sending states of all video data senders, so as to facilitate finding a suitable game video source to the user terminal; based on the network positions of the user terminal and all target video data senders in the 5G network, a communication channel between the target video data sender and the user terminal is constructed to perform efficient and stable game video transmission to the user terminal; when it is necessary to switch the communication channel for game video transmission to the user terminal, another communication channel between the target video data sender and the user terminal is constructed to continue to perform game video transmission to the user terminal, thereby improving the smoothness and stability of game video transmission.

[0062] In another embodiment, based on a game video acquisition request of a user terminal, determining game video attribute information that the user terminal expects to obtain; based on the game video attribute information, determining all video data senders matching the user terminal from the 5G network, including:

[0063] Parse and process the game video acquisition request of the user terminal to obtain the video file name information corresponding to the game video display task that the user terminal currently needs to execute;

[0064] The video file name information is compared with the video file storage directories of all video data senders under the 5G network. If the video file storage directory contains the video file name information, the corresponding video data sender is determined as the video data sender that matches the user terminal, and the network gateway addresses of all video data senders that match the user terminal within the 5G network are obtained.

[0065] The beneficial effect of the above embodiment is that when the user terminal such as a smart phone or a portable computer held by the user needs to display a game video, a game video acquisition request is initiated externally, the game video acquisition request is parsed and processed, and the video file name information corresponding to the game video display task currently required to be executed by the user terminal is obtained, so as to facilitate the subsequent accurate retrieval of the corresponding game video according to the video file name information and transmit it to the user terminal, and provide a reliable video data source for the user terminal to display the game video. In addition, the video file name information is compared with the video file storage directory of each of all video data sending terminals under the 5G network. If the video file storage directory contains the video file name information, the corresponding video data sending terminal is determined as a video data sending terminal matching the user terminal, and the network gateway address of all video data sending terminals matching the user terminal in the 5G network is obtained, so that all video data sending terminals storing the video data required for the user terminal to display the game video can be screened out, and the network gateway connected to the 5G network is calibrated, so as to facilitate the subsequent accurate determination of the network path length between the user terminal and the video data sending terminal in the 5G network.

[0066] In another embodiment, based on the respective video data transmission states of all video data transmission terminals, all target video data transmission terminals that can transmit the corresponding game video to the user terminal are determined from all video data transmission terminals; based on the network positions of the user terminal and all target video data transmission terminals in the 5G network, a target video data transmission terminal is selected to form a communication channel with the user terminal, so as to transmit the game video to the user terminal, including:

[0067] Analyze the video sending logs of all video data sending ends matching the user end, and determine the estimated sending time information of the video data of the game video that the user end expects to obtain from all video data sending ends;

[0068] Based on the estimated sending time information and the estimated playing time information of the game video that the user terminal expects to obtain, determine the time difference between the two; if the time difference is greater than or equal to a preset time difference threshold, determine the corresponding video data sending end as a target video data sending end that can send the corresponding game video to the user terminal;

[0069] Based on the network gateway addresses of the user terminal and all target video data senders within the 5G network, the network path length between the user terminal and each target video data sender within the 5G network is determined, and the target video data sender with the smallest network path length is selected to establish a communication channel with the user terminal, thereby transmitting the game video to the user terminal.

[0070] The beneficial effect of the above embodiment is to analyze the respective video sending logs of all video data sending ends matching the user end, obtain the corresponding video data sending queue of each video data sending end during the video data sending process, analyze the video data sending queue, obtain the estimated sending time information of the video data of the game video that the user end expects to obtain from each video data sending end, and then determine the time difference between the estimated sending time information and the estimated playing time information of the game video that the user end expects to obtain. If the time difference is greater than or equal to the preset time difference threshold, it indicates that the corresponding video data sending end can completely transmit the video data to the user end before the user end plays the game video, and the corresponding video data sending end is determined as the target video data sending end that can send the corresponding game video to the user end, thereby providing different video data sending end options for sending video data to the user end. Based on the network gateway addresses of the user terminal and all target video data senders within the 5G network, the network path length between the user terminal and each target video data sender within the 5G network is determined, and the target video data sender with the smallest network path length is selected to form a communication channel with the user terminal, thereby ensuring efficient and fast video data transmission to the user terminal.

[0071] In another embodiment, based on the game video transmission state information of the selected target video data transmitting end, it is determined whether it is necessary to switch the communication channel for transmitting the game video to the user end; when it is necessary to switch the communication channel, another target video data transmitting end is selected from all target video data transmitting ends to establish another communication channel with the user end, so as to continue to perform the game video transmission work to the user end, including:

[0072] Obtaining an average transmission speed of a game video of a selected target video data transmitting end; if the average transmission speed of the game video is less than a preset transmission speed threshold, determining that it is necessary to switch a communication channel for transmitting the game video to the user end; otherwise, determining that it is not necessary to switch a communication channel for transmitting the game video to the user end;

[0073] When it is necessary to switch the communication channel for transmitting the game video to the user terminal, based on the network path length between the user terminal and each target video data sending terminal within the 5G network, select the target video data sending terminal with the second minimum network path length to build another communication channel with the user terminal; and based on the game video data reception record of the user terminal, continue to perform the game video transmission work to the user terminal.

[0074] The beneficial effect of the above embodiment is to detect the speed of sending the game video from the target video data sending end currently connected to the user end to the user end, obtain the average transmission speed of the game video of the selected target video data sending end, and compare the threshold of the average transmission speed of the game video. If the average transmission speed of the game video is less than the preset transmission speed threshold, it indicates that the current game video transmission speed is too slow to ensure that the entire game video can be transmitted before the user end needs to display the game video. At this time, it is judged that the communication channel for transmitting the game video to the user end needs to be switched. When it is necessary to switch the communication channel for transmitting the game video to the user end, based on the network path length between the user end and each target video data sending end within the 5G network, the target video data sending end with the second minimum network path length is selected to form another communication channel with the user end, thereby switching the communication channel in time to improve the efficiency and reliability of transmitting the game video to the user end.

[0075] In another embodiment, after the target video data transmitting end establishes a communication channel with the user end, the transmission data is encrypted and compressed before data transmission, and the transmission data is decrypted and restored after the data transmission is completed.

[0076] Step S1, using the following formula (1), according to the terminal information data of the target video data sending end and the user end, encrypt the transmission data,

[0077]

[0078] In the above formula (1), d 16 Indicates the hexadecimal form of the encrypted transmission data after the transmission data is encrypted; D 16 Indicates the hexadecimal form of the transmitted data; Indicates the circular right shift symbol; F 16 The hexadecimal format of the terminal information data of the target video data sending end; Y 16 Indicates the hexadecimal form of the terminal information data of the user end; len() indicates the total number of digits of the hexadecimal data in the brackets;

[0079] Step S2, using the following formula (2), based on the terminal information data of the target video data sending end and the user end, the encrypted transmission data is compressed.

[0080] d' 16 =d 16 -{(F 16 +Y 16 )>>[len(F 16 +Y 16 )-1]} (2)

[0081] In the above formula (2), d' 16 Indicates the hexadecimal data after data compression of the encrypted transmission data; >> indicates the right shift sign; d' 16 Transmitted as actual transmission data;

[0082] Step S3, after the data transmission is completed, the following formula (3) is used to restore the transmitted data according to the terminal information data of the target video data sending end and the user end.

[0083]

[0084] In the above formula (3), D' 16 Indicates the hexadecimal data after the actual transmission data is restored; Indicates a circular left shift sign.

[0085] The beneficial effect of the above embodiment is that the transmission data is encrypted according to the terminal information data of the target video data sending end and the user end by using the above formula (1), so that the encryption is performed using the fixed parameters of the transmission, which ensures the reliability of the encryption and makes the encryption process simple and efficient; then the above formula (2) is used to compress the encrypted transmission data according to the terminal information data of the target video data sending end and the user end, thereby shortening the data, reducing the data transmission time, and improving the system efficiency; finally, the above formula (3) is used to restore the transmission data according to the terminal information data of the target video data sending end and the user end, so that the data is automatically restored to ensure the accuracy of the data and the reliability of the transmission.

If the video file storage directory contains the video file name information, the corresponding video data sending terminal is determined as a video data sending terminal matching the user terminal, and the network gateway address of all video data sending terminals matching the user terminal in the 5G network is obtained, so that all video data sending terminals storing the video data required for the user terminal to display the game video can be screened out, and the network gateway connected to the 5G network is calibrated, so as to facilitate the subsequent accurate determination of the network path length between the user terminal and the video data sending terminal in the 5G network.

[0099] In another embodiment, the target video data sending end determination module is used to determine all target video data sending ends that can send the corresponding game video to the user end from all video data sending ends based on the respective video data sending states of all video data sending ends, including:

[0100] Analyze the video sending logs of all video data sending ends matching the user end, and determine the estimated sending time information of the video data of the game video that the user end expects to obtain from all video data sending ends;

[0101] Based on the estimated sending time information and the estimated playing time information of the game video that the user terminal expects to obtain, determine the time difference between the two; if the time difference is greater than or equal to a preset time difference threshold, determine the corresponding video data sending end as a target video data sending end that can send the corresponding game video to the user terminal;

[0102] The communication channel construction module is used to select a target video data sending end to form a communication channel with the user end based on the network positions of the user end and all target video data sending ends in the 5G network, so as to transmit the game video to the user end, including:

[0103] Based on the network gateway addresses of the user terminal and all target video data senders within the 5G network, the network path length between the user terminal and each target video data sender within the 5G network is determined, and the target video data sender with the smallest network path length is selected to establish a communication channel with the user terminal, thereby transmitting the game video to the user terminal.

[0104] The beneficial effect of the above embodiment is to analyze the respective video sending logs of all video data sending ends matching the user end, obtain the corresponding video data sending queue of each video data sending end during the video data sending process, analyze the video data sending queue, obtain the estimated sending time information of the video data of the game video that the user end expects to obtain from each video data sending end, and then determine the time difference between the estimated sending time information and the estimated playing time information of the game video that the user end expects to obtain. If the time difference is greater than or equal to the preset time difference threshold, it indicates that the corresponding video data sending end can completely transmit the video data to the user end before the user end plays the game video, and the corresponding video data sending end is determined as the target video data sending end that can send the corresponding game video to the user end, thereby providing different video data sending end options for sending video data to the user end. Based on the network gateway addresses of the user terminal and all target video data senders within the 5G network, the network path length between the user terminal and each target video data sender within the 5G network is determined, and the target video data sender with the smallest network path length is selected to form a communication channel with the user terminal, thereby ensuring efficient and fast video data transmission to the user terminal.

[0105] In another embodiment, the game video transmission state identification module is used to determine whether it is necessary to switch the communication channel for transmitting the game video to the user terminal based on the game video transmission state information of the selected target video data sending terminal, including:

[0106] Obtaining an average transmission speed of a game video of a selected target video data transmitting end; if the average transmission speed of the game video is less than a preset transmission speed threshold, determining that it is necessary to switch a communication channel for transmitting the game video to the user end; otherwise, determining that it is not necessary to switch a communication channel for transmitting the game video to the user end;

[0107] The communication channel switching module is used to select another target video data sending end from all target video data sending ends to build another communication channel with the user end when the communication channel needs to be switched, so as to continue to perform the game video transmission work for the user end, including:

[0108] When it is necessary to switch the communication channel for transmitting the game video to the user terminal, based on the network path length between the user terminal and each target video data sending terminal within the 5G network, select the target video data sending terminal with the second minimum network path length to build another communication channel with the user terminal; and based on the game video data reception record of the user terminal, continue to perform the game video transmission work to the user terminal.

[0109] The beneficial effect of the above embodiment is to detect the speed of sending the game video from the target video data sending end currently connected to the user end to the user end, obtain the average transmission speed of the game video of the selected target video data sending end, and compare the threshold of the average transmission speed of the game video. If the average transmission speed of the game video is less than the preset transmission speed threshold, it indicates that the current game video transmission speed is too slow to ensure that the entire game video can be transmitted before the user end needs to display the game video. At this time, it is judged that the communication channel for transmitting the game video to the user end needs to be switched. When it is necessary to switch the communication channel for transmitting the game video to the user end, based on the network path length between the user end and each target video data sending end within the 5G network, the target video data sending end with the second minimum network path length is selected to form another communication channel with the user end, thereby switching the communication channel in time to improve the efficiency and reliability of transmitting the game video to the user end.

[0110] In general, the game video transmission method and system based on the 5G network determines all video data senders that match the user terminal from the 5G network based on the game video attribute information that the user terminal expects to obtain, and determines all target video data senders that can send corresponding game videos to the user terminal based on the respective video data sending states of all video data senders, so as to facilitate finding a suitable game video source for the user terminal; based on the network positions of the user terminal and all target video data senders in the 5G network, a communication channel between the target video data sender and the user terminal is constructed to perform efficient and stable game video transmission to the user terminal; when it is necessary to switch the communication channel for game video transmission to the user terminal, another communication channel between the target video data sender and the user terminal is constructed, so as to continue to perform game video transmission to the user terminal, thereby improving the smoothness and stability of game video transmission.
