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 playback switching system according to an embodiment of the present 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 playback switching method according to an embodiment of the present invention. In step S201, an authentication message and a first operation message are first transmitted by the user terminal 101 to the remote server 103. The authentication message may be manually input by the user, or may be automatically transmitted after being stored in the user terminal 101. The first operation message is various forms of user input such as touch, mouse, keyboard, gesture recognition, etc. of the user with respect to the user terminal 101, and the remote server 103 performs various operations on the corresponding game application remotely according to the user input by receiving the first operation message. The remote server 103 will verify the received authentication message and upon authentication of the authentication message sent by the user terminal 101, the remote server 103 will send an audio media stream and a video media stream to the user terminal 101 that allow the user to remotely operate through a game application installed on the remote server 103 and receive media content without creating the media content locally from the user terminal 101, 102 on their own. For the video media stream, the relevant output functions of DirectX, OpenGL standards when the remote server 103 runs the game application program may be intercepted, and the intercepted image frames may be buffered and compressed into the video media stream according to the standards such as h.264 and the like for transmission. For the audio media stream, relevant output functions of DirectSound, XAudio and other standards can be intercepted, and intercepted sound waveforms are collected through a virtual audio device and transmitted after being compressed into the audio media stream according to AAC and other standards. After reception, the user terminal 101 then presents the received audio media stream and video media stream to the user.
In step S202, the user may need to switch from the user terminal 101 to the user terminal 102 and continue the current game progress. 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 ongoing game process from the mobile terminal to the fixed terminal when entering the living room of the home, for example. A preferred way is to automatically perform the handover when it is detected that the user terminal 101 and the user terminal 102 have the same Service Set Identification (SSID), which may for example belong to a home-wide Wi-Fi network, and to switch the ongoing game progress of the user terminal 101 to the user terminal 102. The remote server 103, having transmitted the audio media stream and the video media stream to the user terminal 101, will establish a transition time period for estimating the delay caused by the handover and preparing for synchronization when receiving the authentication message again from a different user terminal 102. The transition time period is preferably proportional to the larger of the first average communication delay between the user terminal 101 and the remote server 103 and the second average communication delay between the second user terminal 102 and the remote server 103. The average communication delay may be derived based on a number of samples of the delay over a certain time period, e.g., 30 seconds. The communication delay includes propagation and transmission delays and thus may be different for each user terminal. For example, if the first average communication delay is 100 ms and the second average communication delay is 300 ms, the transition time period may be defined as a multiple of the second average delay, such as 600 ms, 1200 ms, 1800 ms, etc. to prepare the appropriate time length for the subsequent step.
In step S203, the transmission of the video media stream to the user terminal 102 based on the first operation message is continued and the transmission of the video media stream to the user terminal 101 is stopped by the remote server 103 for the transition time period. While the remote server 103 may begin receiving and storing input from the user terminal 102 (if any) at this point, the video media stream and the audio media stream are still transmitted according to the first operation message sent by the user terminal 101. The audio media stream is still transmitted to the user terminal 101, the video media stream is transmitted to the user terminal 102, and the user terminal 101 may display a prompt message to prompt the user that the preparation stage of switching has been currently entered. At this time, the relative delay between the user terminal 101 and the user terminal 102 may be determined according to the comparison of the corresponding timestamps in the audio media stream played by the user terminal 101 and the video media stream played by the user terminal 102, and the remote server 103 may adjust the relative delay according to the relative delay so as to avoid the mismatch of the progress of the game application after the switching is completed, and the relative delay may be further used to compensate the out-of-sync of progress between the user terminal 101 and the user terminal 102 in step S204. In this way, the estimation of the relative delay does not require the execution of additional algorithms nor estimation by the remote server 103 side, but can be calculated at the user terminal side in a more accurate manner by the actual playing effect of the user terminal 101 and the user terminal 102. The user may also, for example, intuitively choose whether to continue the switching process from whether the audio media stream and the video media stream can be synchronized, and in the case of an excessive asynchronization between the audio media stream and the video media stream, may determine that the network connection of the user terminal 102 has failed, and manually terminate the automatic switching process.
In step S204, the video media stream and the audio media stream are transmitted to the user terminal 102 and the audio media stream is stopped from being transmitted to the user terminal 101 by the remote server 103 after the transition time period elapses based on the second operation message including the user' S input to the user terminal 102 after the transition time period elapses. The switching process is finally completed in step S204, and after the synchronization is performed in step S203 by compensating for the relative delay through the timestamp comparison of the audio media stream and the video media stream respectively played by the user terminal 101 and the user terminal 102, the transmission to the user terminal 101 may be ended and both the audio media stream and the video media stream may be transmitted to the user terminal 102 according to the user input of the user terminal 102. This handover procedure will significantly reduce the out-of-sync phenomenon, allowing better real-time continuation of the previous progress when handing over from the user terminal 101 to the user terminal 102. The difference between the first and second average communication delays of the user terminal 101 and the user terminal 102, respectively, may be detected by the remote server 103 and, if the difference exceeds a delay threshold, the second operational message may be caused to include a portion of the user's input to the user terminal 101 during the transition time period. The portion is a user input to the user terminal 101 for a length of time equal to the delay threshold and ending at the end of the transition time period. When the communication delay between the user terminal 101 and the user terminal 102 differs too much, the user may experience a significant lack of synchronization after the handover, and therefore it is necessary to compensate for this by additionally replaying the part of the phase difference at the user terminal 102 on the basis of the previously stored first operation message of the time range of the length of the delay threshold. The delay threshold may be predefined as a fixed value, such as 500 ms, 1S, etc., or may be changed according to the larger one of the first and second average communication delays, and is in direct proportion to the larger one, and the delay threshold is preferably also in direct proportion to the relative delay obtained in step S203 according to the comparison between the timestamps in the audio media stream of the user terminal 101 and the video media stream of the user terminal 102.
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.
