Description
Technical Field
The present invention belongs to the field of computer communication technology, and more particularly, to a media transmission method and system.
Background
The delivery of various audio and video media streams to users via streaming technology is a common situation that occurs at present when users play online entertainment such as networked movies, network televisions, cloud games, and the like. The online entertainment of the user can be realized through various user terminals, such as a mobile phone, a tablet computer, a desktop computer, a notebook computer, an intelligent television, a set-top box, a portable game machine and the like. If a user has more than two user terminals at the same time, switching between user terminals may be required during online entertainment, which requires minimizing user inconvenience caused by interruptions during switching. Such as a user watching a video on a balcony with a cell phone or playing a cloud game, and entering a living room may want to turn to continue on a computer display on a previous schedule. Current users may need to perform multiple networking authentications through complex and time consuming physical wiring or between two devices that need to be switched over, and the user experience will be compromised by the forced interruption of the video or game.
Disclosure of Invention
It is an object of the invention to enable a smooth handover of a user when selecting other devices to continue media transmission, such that no disruption of the user experience may be caused.
The invention discloses a media transmission method, which comprises the steps that a first user terminal sends an authentication message to a remote server; sending, by the remote server, the audio media stream and the video media stream to the first user terminal when the authentication message sent by the first user terminal passes authentication; sending, by the first user terminal, a handover message and an authentication message to the second user terminal; the second user terminal sends an authentication message to the remote server after receiving the switching message; the remote server also sends the audio media stream and the video media stream to the second user terminal when the authentication message sent by the second user terminal passes the authentication; recording, by the remote server, a relative difference in user operating frequencies received by the first user terminal and the second user terminal over a fixed time period; and if the first user terminal and the second user terminal do not send or receive the switching message within the fixed time period, the remote server stops sending the audio media stream and the video media stream to one user terminal with lower user operation frequency in the first user terminal and the second user terminal only when the relative difference is larger than or equal to a preset switching threshold value after the fixed time period.
The invention also discloses a media transmission system, which comprises a first user terminal, a second user terminal and a remote server, wherein the first user terminal is configured to send an authentication message to the remote server; the remote server sends the audio media stream and the video media stream to the first user terminal when the authentication message sent by the first user terminal passes the authentication; the first user terminal sends a switching message and an authentication message to the second user terminal; the second user terminal sends an authentication message to the remote server after receiving the switching message; the remote server also sends the audio media stream and the video media stream to the second user terminal when the authentication message sent by the second user terminal passes the authentication; recording, by the remote server, a relative difference in user operating frequencies received by the first user terminal and the second user terminal over a fixed time period; and if the first user terminal and the second user terminal do not send or receive the switching message within the fixed time period, the remote server stops sending the audio media stream and the video media stream to one user terminal with lower user operation frequency in the first user terminal and the second user terminal only when the relative difference is larger than or equal to a preset switching threshold value after the fixed time period.
Preferably, if the first user terminal sends the handover message to the second user terminal again within the fixed time period, the remote server will stop sending the audio media stream and the video media stream to the first user terminal without waiting for the end of the fixed time period.
Preferably, if the second user terminal sends the handover message to the first user terminal within a fixed time period, the remote server will stop sending the audio media stream and the video media stream to the second user terminal without waiting for the end of the fixed time period.
Preferably, the relative difference being greater than or equal to the preset handover threshold corresponds to one of the first and second user terminals having an operating frequency three times or more greater than that of the other.
Preferably, the fixed time period is five seconds.
Preferably, the authentication message comprises a username and password.
Preferably, the first user terminal is a portable mobile terminal.
The embodiment of the invention is beneficial to smoothly switching the user terminals for receiving the media transmission, so that the user can automatically select the required user terminal without excessive manual operation of the user when performing online entertainment activities such as video playing, cloud games and the like, and the embodiment is particularly suitable for ensuring that the user does not interrupt the user experience under the condition of frequently switching the user terminals.

Detailed Description
The terms first, second, third, upper, lower, left, right, and the like do not limit the particular positions of the elements, nor do they define any direction or order of limitations. The preferred embodiments disclosed herein are to facilitate understanding only by those skilled in the art and are not intended to limit the scope of the disclosure, which includes various equivalent or alternative embodiments under the principles of the disclosed embodiments and what those skilled in the art can readily infer from the disclosure.
Fig. 1 is a schematic diagram of a media transmission system according to an embodiment of the invention. The media transmission system comprises a user terminal 101, a user terminal 102 and a remote server 103. The user terminals 101 and 102 may be various types of user terminals with network communication functions, such as mobile phones, tablet computers, desktop computers, notebooks, smart televisions, set-top boxes, portable game machines, head-mounted displays, wearable smart devices, and media players. The user terminals 101 and 102 may communicate with the remote server 103 according to any wired or wireless network such as ethernet, LAN, fiber network, 4g lte, Wi-Fi, bluetooth, wireless local area network WLAN, global system for mobile communications GSM, code division multiple access CDMA, WCDMA, time division multiplexing TDM, etc., or may communicate with each other. Preferably, the user terminal 101 is a mobile user terminal or a portable user terminal, while the user terminal 102 is a relatively large stationary home user terminal. The user terminal 101 stores authentication messages such as a user name and a password registered in the remote server 103 in advance, and the user terminal 102 does not need to store the authentication messages in advance but can obtain the authentication messages by communicating with the user terminal 101.
Fig. 2 is a flowchart of a media transmission method according to an embodiment of the present invention. In step S201, the user terminal 101 transmits an authentication message to the remote server 103, and the authentication message may be manually input by the user or may be automatically transmitted after being stored in the user terminal 101 in advance. The remote server 103 checks the received authentication message and when the authentication message sent by the user terminal 101 is authenticated, the remote server 103 sends an audio media stream and a video media stream to the user terminal 101, wherein the audio media stream and the video media stream may be media contents such as video programs and the like, or may constitute cloud game contents, so that the user can remotely operate through an application installed on the remote server 103 and receive the media contents without creating the media contents locally from the user terminal 101, 102. The user terminal 101 then presents the received audio and video media streams to the user.
In step S202, the user may need to switch from user terminal 101 to user terminal 102 without interrupting the presentation of the audio and video media streams. At this time, the user manually or automatically transmits a handover message indicating that the user wants to perform handover and the above authentication message to the user terminal 102 through the user terminal 101. After receiving the handover message and the authentication message, the user terminal 102 transmits the authentication message to the remote server 103. Preferably the authentication message may be sent to the user terminal 102 after encryption and subsequently decrypted at the remote server 103 and not stored on top of the user terminal 102. The handover message may be controlled manually by the user or automatically by the user terminal 101, 102. For example, the user may manually select any of the other user terminals in the home for switching among the applications installed on the user terminal 101. For another example, the distance between the user terminals 101 and 102 may be determined by the signal strength of the communication, and the switching may be automatically performed once the distance reaches a predetermined range, which may enable the user to automatically switch the media playing from the mobile terminal to the fixed terminal when entering the living room of the home, for example. When the remote server 103 has already transmitted the audio media stream and the video media stream to the user terminal 101 and receives the authentication message from the different user terminal 102 again, it will start to transmit the same audio media stream and video media stream to the user terminal 102, but will not immediately stop transmitting to the user terminal 101, so as to avoid interruption of user experience due to frequent terminal switching when the user operates the user terminals 101, 102 by mistake or needs to operate the user terminals 101, 102 simultaneously, and also avoid unnecessary high frequency switching when the user only intermittently reaches the switching condition in a short time in the case of automatic switching. This is particularly applicable to cases such as high-definition video that requires buffering or cloud games that require continuous, frequent operations.
In step S203, in the case where the remote server 103 has started transmission of the audio media stream and the video media stream to the user terminal 102. The remote server 103 starts recording the relative difference in the user operation frequency received by the user terminal 101 and the user terminal 102 for a fixed period of time to determine whether to continue to perform the handover operation. The user operation frequency is the number of user operations per second obtained by averaging the number of user operations of each user terminal in the fixed time period. The fixed time period should be set to be in the range of 1-10 seconds, preferably 5 seconds, in consideration of the moving characteristics of the user in the home scene. When the remote server 103 starts the fixed time period, a corresponding indication message may be sent to the user terminal 101, 102, together with the length of the fixed time period. The user terminals 101, 102 record the respective user operation times after receiving the indication message, and transmit the recorded user operation times to the remote server 103 after the fixed time period expires. The user terminals 101, 102 and the remote server 103 may communicate information such as timestamps of the video stream and the audio stream to each other for synchronization. The remote server 103 keeps streaming audio and video media to both user terminals 101, 102 for a fixed period of time, so that the user can still continue to operate on either user terminal.
In step S204, if no more handover messages are sent or received by both the user terminal 101 and the user terminal 102 within the fixed time period, the remote server 103 will determine whether the handover action should be completed after the fixed time period ends. The audio media stream and the video media stream are only stopped from being transmitted to the user terminal 101, 102 with the lower user operation frequency when the relative difference of the user operation frequencies is greater than or equal to the preset switching threshold. The switching threshold preferably corresponds to three times the user operation frequency of one user terminal as the other, e.g. when the user operation frequency of the user terminal 101 is 1 time per second within a fixed time period and the user operation frequency of the user terminal 102 is 3 times per second within the fixed time period, the remote server 103 decides that the media streaming to the user terminal 102 should be maintained and stops streaming to the user terminal 101. If the relative difference in the user operating frequencies in the user terminals 101, 102 is less than the handover threshold value within the fixed time period, the media streaming is maintained for both user terminals 101, 102 so that the user uses both user terminals simultaneously. If the media stream transmission is performed on both the ues 101 and 102, a new fixed time period may be started after a certain time interval (e.g. 1 minute), and it may be determined again whether the relative difference between the operating frequencies of the ues is greater than or equal to the handover threshold, or it may wait for one ue to send the handover message again. The above decision steps within a fixed time period are suitable for reducing unnecessary high frequency handovers and for maintaining the continuity of the user experience. If the user again uses one of the user terminals 101, 102 to send a switching message to the other within the fixed time period described above, the user terminal receiving the switching message may notify the remote server 103 that the remote server 103 will stop sending audio media streams and video media streams to the user terminal sending the switching message without waiting for the end of the fixed time period. When the user sends the switching message again in a fixed time period, the possibility of misoperation or automatic switching continuous condition triggering is low, and at the moment, the judgment based on the user confirmation for switching is immediately switched without using a mode of waiting for the fixed time period to end and then automatically judging. If the user needs to switch among more than three user terminals, the media stream transmission to all the user terminals sending the switching message and receiving the switching message can be maintained in a fixed time period by analogy, and the media stream transmission to the user terminal with relatively low user operation frequency is stopped according to the relative difference of the user operation frequency after the fixed time period is finished. These embodiments may both maintain the continuity of the user experience during the fixed time period and allow more accurate reflection of the user's changes to the user terminal that require handover by further judgment within the fixed time period.
Other various methods and systems in accordance with embodiments of the present concepts and principles will be apparent to those skilled in the art from consideration of the drawings and description. All such methods and systems are included within the scope of the present disclosure and may be implemented as a computer-implemented software or program product. Further, all embodiments disclosed herein can be implemented individually or combined in any manner and/or in any combination.
