Description
Technical field
The present invention relates to internet television technical field more particularly to a kind of video flow converting methods, video stream conversion
It sets, adaptive method for switching, adaptive switching device, computer equipment and computer readable storage medium.
Background technique
OTT TV (hereinafter referred to as OTT) abbreviation internet television generallys use unicast in existing mainstream solution
It is transmitted.The advantages of unicast be server timely respond to user demand, personalized service easy to accomplish, but disadvantage be also it is aobvious and
It is clear to: such as big using unicast upper layer network pressure, CDN (CDN, content delivery network, content delivery network
Network) equipment investment and network bandwidth occupy it is more.One of the scheme for solving this problem is exactly using multicasting technology, and use is identical
An identical group of shared data stream is added in the terminal of data flow, significantly reduces the burden of the distribution server, meanwhile, backbone network
Within the scope of programme televised live flow in network will maintain centainly, mitigate content supplier's egress network and network significantly
The pressure of provider backbone network.
But there is also following disadvantages for multicasting technology: first is that terminal capabilities is more demanding, terminal needs to record multicast list, right
Terminal capabilities is more demanding.And it is poor by terminal record multicast list flexibility, if multicast list is changed, need firmware
Upgrading is just able to achieve；Second is that it is more demanding to multicast data flow, if intermediate cutout situation occur, it will seriously affect user and watch body
It tests.
In conclusion can reduce upper layer network pressure ensures that user's viewing experience, and terminal capabilities is required not
High solution becomes internet television technical field urgent problem to be solved.
Summary of the invention

Whether network segment and default access network segment are consistent, if unanimously, illustrating that accessing network segment supports multicast, then to medium converter server
It sends multicast and application is added, played out with obtaining group broadcasting video frequency resource；If inconsistent, illustrate that accessing network segment does not support group
It broadcasts, supports unicast, then unicast video stream address is sent to medium converter server, so that medium converter server is carrying
The unicast video resource with unicast video stream address matching is found out in net, medium converter server is regarded unicast by bearer network
Frequency resource is sent to terminal, and terminal, which receives unicast video resource, can carry out unicast broadcasting.The present invention by obtaining electricity in real time
The video flowing address that sub- program guide server issues does not need terminal recording address list, does not need firmware upgrade energy yet
The update for carrying out address list according to the video flowing address that epg server issues in time, requires not terminal capabilities
Height, also, broadcast mode is adaptively switched according to the access network segment of terminal, terminal carries out multicast broadcasting when accessing default network segment,
Otherwise unicast broadcasting is carried out, upper layer network pressure can be reduced again and can guarantee the viewing experience of user.
It should be noted that unicast video stream address and multicast video streams address that epg server issues can
To be stored in the application program of terminal, further, when the access network segment of terminal is consistent with default access network segment, using journey
Multicast video streams address is sent to the media player of terminal by sequence, and address is sent to medium converter clothes by media player
Business device, when the access network segment of terminal and inconsistent default access network segment, unicast video stream address is sent to end by application program
Address is sent to medium converter server by media player, that is to say, that when terminal has unicast by the media player at end
Or when multicast request, corresponding unicast video stream address or multicast video streams address are first transmitted to matchmaker by the application program of terminal
Body player, then address is sent to medium converter server by media player.
Fig. 7 shows the flow diagram of the adaptive method for switching of another embodiment of the present invention offer.Such as Fig. 7 institute
Show, method includes:
Step 702, it obtains in real time and saves the unicast video stream address issued by epg server and multicast
Video flowing address；
