Problems solved by technology

[0002] Most of the multimedia devices now support WiFi, Ethernet, 3G / 4G / 5G and other network access methods. When playing Internet program sources on video terminals, you will encounter multiple network types at the same time When 5G access is switched to WiFi / wired connection, when the above situation is encountered, when the video terminal device plays Internet programs, the video application connection needs to be switched from one network connection to another network connection. Since network connection switching takes time, this If there is no program source data stream for a period of time, the playback application will experience freezes or black screens due to missing video data frames, and seamless playback cannot be achieved, or the video application may replay from the beginning of the video data stream, and continuous playback cannot be performed. Seriously affect the user's online playback experience

Embodiment 1

[0044] The video terminal accesses the network. The video terminal device supports multiple types of network access. The terminal system supports the network access failover function, that is, when a certain network access fails or fails, it will automatically try to use another network type to access. , when multiple network types are connected at the same time, the system automatically configures the routing gateway according to the preset network type access priority. For data services such as video applications, the network connection to the server is performed according to the network type access priority, such as priority : Ethernet>WiFi>3G / 4G / 5G, the video application uses Ethernet first to connect to the server, if it fails, try the network connection with lower priority in turn.

[0045] Video app network connection toggle.

[0046] The network access of the terminal device is disconnected due to abnormality or other circumstances. At this time, the terminal system au...

Embodiment 2

[0048] The terminal device has network access. If there is a higher priority network type access at this time, the video application system needs to switch to the higher priority network type connection. When switching, the original network connection of the video application system 1 don't break,

[0049] The new network connection 2 connects at time T1, connects to the network server at time T2, T2-T1 is the network switching time,

[0050] The position where the video application plays is represented by p3. Such as Figure 3b shown.

[0051] At T2 time, if there is still data in the video data buffer area of ​​network connection 1, record the last byte data position of the buffer area of ​​the video data stream of network connection 1 (that is, the obtained network video stream position) at T2 time, assuming that the position is marked with pe , T2 closes the network connection 1 network connection at all times, and no longer requests data. Network connection 2 requests...

Abstract

The embodiment of the invention provides a method for realizing seamless playing of a network connection switching video stream, and the method comprises the following steps that UE employs a first network connection to play a video file, and obtains a first moment t1 of the first network connection at the video file; when the UE determines that a second network connection is accessed, a second moment t2 of the second network connection at the video file is determined according to the t1; and the UE sends a video request to a server of the video file, the video request is used for requesting avideo after the t2 moment, and the UE receives and plays the video after the t2 moment. The technical scheme provided by the invention has the advantage of high user experience.

Description

technical field [0001] The present application relates to the technical field of video terminal equipment, and in particular to a method for realizing seamless playback of video streams switched between network connections and related products. Background technique [0002] Most of the multimedia devices now support WiFi, Ethernet, 3G / 4G / 5G and other network access methods. When playing Internet program sources on video terminals, you will encounter multiple network types at the same time When 5G access is switched to WiFi / wired connection, when the above situation is encountered, when the video terminal device plays Internet programs, the video application connection needs to be switched from one network connection to another network connection. Since network connection switching takes time, this If there is no program source data stream for a period of time, the playback application will experience freezes or black screens due to missing video data frames, and seamless pla...
