step S203, the UE sends a video request to the server of the video file, the video request is used for requesting the video after the time t2, and the UE receives and plays the video after the time t 2.
According to the technical scheme, a first network connection is adopted to play the video file, and the first time t1 of the first network connection at the video file is obtained; when the UE determines that a second network connection is accessed, determining a second time t2 of the second network connection at the video file according to the t 1; and the UE sends a video request to the server of the video file, the video request is used for requesting the video after the time t2, and the UE receives the video after the time t2 and plays the video. Therefore, the UE does not need to request the video at the starting moment of the video file, so that the data volume of network transmission is reduced, seamless playing of the video is realized, and the user experience is improved.
In an alternative arrangement, the first and second electrodes may be,
the second network connection is a high priority connection, such as wifi or the like. The first network connection may be any of 3G/4G/5G connections. Of course, the second network connection may be any of 3G/4G/5G connections.
In an optional scheme, the determining, according to the t1, that the second network connection is at the second time t2 of the video file may specifically include:
if the first network connection is disconnected, it is determined that t1 is the last position P1 obtained from the video file by the first network connection, and it is determined that P1 is the corresponding position at the second time t 2. Namely, t1 is t 2. Assuming that the first network connection sees the 20 th minute position of the video file, t2 is determined directly to be 20 minutes.
In an optional scheme, the determining, according to the t1, that the second network connection is at the second time t2 of the video file may specifically include:
if the first network connection is not disconnected, determining the time x of successful switching of the second network connection, and determining that t2 is x + [ delta ] t; t2 is not less than t1, the UE plays the video file at t2 using the second network connection, where t1 is the time corresponding to the last location obtained from the video file by the first network connection.
In an alternative arrangement, the first and second electrodes may be,

Example one
The video terminal accesses the network, the video terminal equipment supports the access of various network types, the terminal system supports the function of network access failover, namely when a certain network access fails or fails, the other network type is automatically tried to be accessed, when the various network types are accessed simultaneously, the system automatically performs the configuration of a routing gateway according to the preset network type access priority, and for data services such as video application and the like, the network connection to a service end is performed according to the network type access priority, such as the priority: ethernet > WiFi >3G/4G/5G, the video application preferentially uses the Ethernet to carry out connection to the service end, and if the video application fails, network connection with low priority is sequentially tried.
And switching the network connection of the video application.
When the network access of the terminal equipment is disconnected due to abnormality or other conditions, the terminal system automatically tries other types of network access at the moment, if the access is successful, the video application system reestablishes the connection to the network server, referring to fig. 3a, if the last video data stream position acquired from the server by the previous network connection 1 is p1, the video application system saves the p1 position, and after the previous network connection 1 is reconnected to the server by using another network type, a data request is initiated from the p1 position of the network video data stream, and the data request is seamlessly connected with the video data stream position acquired by the network connection 1 instead of requesting data from the start position of the video stream again.
Example two
The terminal equipment has network access, if the terminal equipment has network type access with higher priority, the video application system needs to be switched to the network type connection with higher priority, when the terminal equipment is switched, the original network connection 1 of the video application system is not disconnected,
the new network connection 2 is connected at time T1, to the network server at time T2, T2-T1 are network switch times,
the location where the video application plays is denoted by p 3. As shown in fig. 3 b.
At time T2, if the video data buffer of network connection 1 has more data, the last byte data position (i.e. the position of the obtained network video stream) of the video data stream buffer of network connection 1 is recorded at time T2, and assuming that the position is marked by pe, the network connection 1 is closed at time T2, and no data is requested any more. The network connection 2 starts to request the video data stream from the pe position, and after the buffer area of the network connection 1 is completely played, the video data stream starts to be played from the start position (the pe position of the video data stream) of the data stream buffer area of the network connection 2, so that seamless connection playing is realized.
At time T2, if the video data buffer of network connection 1 has no data, the playback position of the data stream of network connection 1 is recorded, the network connection 2 requests the video stream data from the playback position of network connection 1, and the connection of network connection 1 is closed.
