Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment mono-
Referring to Fig. 1, the program request providing for the embodiment of the present invention one is to the schematic flow sheet of live video switching method, and the method comprises the following steps:
Step 101: user end to server sends long connection request, to set up long connection, execution step 102 or step 104 with described server.
In embodiments of the present invention, described server can be Comet server, the long connection of setting up between described client and described server can be http(HTML (Hypertext Markup Language), HTTP-Hypertext transfer protocol) long connection, the long state of server and client side in communicating by letter that make that connect of described http.
Comet server receives after the long connection request of client transmission, can respond described long connection request and long connection of described http hung up, to client, do not return to any request results, now, client can be always in waiting for that Comet server returns to the state of request results.
Step 102: client server is monitoring long first updating message of returning when not overtime and described current live renewal of the page is live video that connects of described foundation, and described the first updating message comprises the current live page and is updated to the message of live video by order video.
When live movable beginning, the live page can be updated to corresponding live video stream by order video stream, now, server can initiatively utilize with client between set up long connection live video updating message (being described the first updating message) is sent to client, allow the live page described in client perception that the switching of order video to live video occurred.
Step 103: client triggers the data flow that player loads described live video when receiving described the first updating message.
When client is after the first updating message of described server push, by resolving described the first updating message, just can know that the renewal of data flow has occurred the live page, be that the live page has been switched to live video by order video, now, client can be by current the loaded order video stream ID(identification of flash player, identify label number) be updated to corresponding live video stream ID, to trigger flash player, load live video stream content, now, flash player can be directly just to play live video content by the redirect of play-on-demand video content.
In addition, after the first updating message described in client end response, can again send described long connection request, to re-establish and be connected with described server.
Step 104: client server is monitoring long second updating message of returning when the overtime and described current live page is not updated to live video that connects of described foundation, and described the second updating message comprises the described current live page and is not updated to the message of live video by order video.
When live activity does not start, be that the live page is not while being updated to corresponding live video stream, if between client and server, set up long is connected to exceed preset the time limit, now server can utilize long connection of foundation that the second updating message is sent to client, and client just can be obtained the described current live page and is not updated to live video by resolving described the second updating message.In addition, after the second updating message described in client end response, can again send described long connection request, to re-establish long connection with described server, so that when live page generation video upgrades, client is by long the first updating message that connects reception server transmission re-establishing.
Further, before step 101, the embodiment of the present invention also comprises: user end to server sends the subscribe request of subscribing to live renewal of the page message subject, so that the first updating message or the second updating message that after subscribing to successfully, reception server returns; Client server responds the subscription success message returning after described subscribe request.Particularly, in order to get in time the described live page, by order video stream, be updated to the updating message of live video stream, client need to send a subscribe request to server, the live renewal of the page message subject pushing with Subscriber, when described in server push during live renewal of the page message subject, client just can be received the first updating message or the second updating message that described live renewal of the page message subject sends, after live renewal of the page message subject success described in client subscription, just can send long connection request to server.
Embodiment bis-
Referring to Fig. 2, the program request providing for the embodiment of the present invention two is to another schematic flow sheet of live video switching method, and the method comprises the following steps:
Step 201: set up long connection, execution step 202 or step 203 with described client after the long connection request that server customer in response end sends.
Step 202: long when connecting not overtime and described current live renewal of the page and being live video when what monitor described foundation, server returns to the first updating message to client, described the first updating message comprises the current live page and by order video, is updated to the message of live video, so that client triggers the data flow that player loads described live video after described the first updating message.
Before step 201, the embodiment of the present invention also comprises: server receives the subscribe request of the live renewal of the page message subject of subscription of client transmission; Server responds described subscribe request, and returns to subscription success message to described client.If monitoring server is live video to current live renewal of the page, can travel through the client of the described live renewal of the page message subject of all subscription, then by long the connection to described each client of setting up with each client, feed back respectively the first updating message.
Step 203: long when connecting the overtime and described current live page and not being updated to live video when what monitor described foundation, server returns to the second updating message to client, and described the second updating message comprises the described current live page and by order video, is not updated to the message of live video.
It should be noted that, only, after the live renewal of the page message subject success of client subscription, the live renewal of the page message subject that server side pushes just can return to the second updating message to client.
The program request that the embodiment of the present invention provides is to live video switching method, when client and server were set up after long connection, whether server can be updated to live video by order video by the current live page of Real-Time Monitoring, if upgraded, server can be to the updating message that described in client push, live renewal of the page is live video stream, and client just can trigger the data flow that player loads described live video after receiving this updating message.By this programme, in net cast activity, user just can switch to live video stream by order video stream automatically without the manual refreshing page, and the defect of having avoided user's manual refreshing page to cause, has improved user's experience.
