Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Embodiments of the invention provide a kind of implementation method of multi-angle video business, as shown in Figure 1, comprising:
Step s101, streaming media server receive the video flowing that the multi-channel video collecting device sends respectively, and the multi-channel video collecting device is gathered the co-current flow media server from different visual angles to same dynamic event respectively and sent video flowing;
When step s102, streaming media server receive user terminal transmission watching of dynamic event asked,, from the video flowing that the multi-channel video collecting device receives, select corresponding vision signal according to watching request;
Step s103, streaming media server send the vision signal of selecting to user terminal.
Below in conjunction with a specific embodiment, the application process of the multi-angle video business that provides in the embodiment of the invention is described in detail.Wherein, multi-angle video system architecture in the embodiment of the invention is based on prior mobile network, as shown in Figure 2, system mainly is made up of video capture device, control and lock unit, streaming media server, transmission network (wireless and fixed network all can) and user terminal, wherein, can also comprise Video processing and compression unit in the system in order to save the Internet resources that consumed in the Streaming Media transmission course.Above-mentioned these parts comprise three parts according to its function: video acquisition part, streaming media server part and user terminal part.
Below respectively the function of each several part is described in detail.
For the video acquisition part, to form by the multi-channel video collecting device, video flowing is gathered and obtained to the multi-channel video collecting device from different visual angles to same dynamic event respectively.Wherein, as shown in Figure 3, for the position of multi-channel video collecting device and dynamic event concerns schematic diagram, this multi-channel video collecting device is placed with arc around dynamic event, and keep identical distance between each multi-channel video collecting device, be that the multi-channel video collecting device carries out the collection of video flowing from different angle intervals (the concrete numerical value of angle intervals is determined by the quantity of video equipment) to same dynamic event, and send the video flowing of gathering.Therefore, a dynamic event can be carried out the collection of video flowing by the multi-channel video collecting device simultaneously from different orientation.In the multi-channel video collecting device of placing, one of them video capture device is as default video capture device, and when certain user terminal initially inserted, the video flowing that streaming media server will this default video capture device collection sent to user terminal.In addition, the position at this default video capture device place as default position, being sent when carrying the request of viewing angle at user terminal, is that benchmark carries out obtaining of the required viewing angle of user terminal with this default position.
For the multi-channel video collecting device, its collection to same dynamic event is triggered by control and lock unit (can be arranged in streaming media server).Control and lock unit send synchronizing signal to each video capture device, and the multi-channel video collecting device was triggered in the identical moment, began same dynamic event is carried out the collection of video flowing.
The video flowing that the multi-channel video collecting device is gathered is handled the Media Stream that receives by Video processing and compression device after arriving Video processing and compression device, and processed video is flowed to the streaming media server transmission.Wherein, control and lock unit can send the coding parameter setting to Video processing and compression device, make Video processing and compression device according to the coding parameter that receives to handling from the video flowing of multi-channel video collecting device collection, thereby the compression ratio and the program quality of the video frequency program that the user is watched are controlled.
For the streaming media server part, when streaming media server receives the video flowing of multi-channel video collecting device transmission, can distinguish the video flowing that receives according to the port (annexation according to each equipment room in the network is provided with as can be known) of the video flowing that receives or according to the sign in the video flowing, promptly streaming media server can know a certain road video flowing is from which video capture device.According to the multi-path video stream that receives, streaming media server receive that user terminal sends watch request the time, in the multi-path video stream that receives, select corresponding vision signal to send according to the content of watching request, thereby provide the multi-angle video business to user terminal to user terminal.
For user terminal, be used for to the watch request of streaming media server transmission dynamic event, and the vision signal of receiving stream media server transmission, to being shown to the user behind the decoding video signal.
Below the interactive mode between user terminal and the streaming media server is elaborated.Can realize based on RTSP (Real Time Streaming Protocol, the real time streaming transport protocol) agreement after the expansion alternately between user terminal and streaming media server below is introduced the RTSP agreement after the expansion that provides among the present invention.
In the embodiments of the invention, provide the operation interface of multi-angle video business to user terminal.A schematic diagram of operation interface as shown in Figure 4, comprising:
Video Play zone: be used for to user and that video display that drives in the wrong direction;
Control button: be used to provide beginning, stop, moment is solidified Frozen Moment and operations such as View Sweeping are swept at the visual angle.
When carrying out corresponding operating on the operation interface of user at user terminal, user terminal generates the RTSP message co-current flow media server transmission of carrying relevant parameter according to user's operation.RTSP protocol extension at the multi-angle video system in the embodiments of the invention is described below:
On original RTSP agreement basis, the SET_PARAMETER in the RTSP protocol message (parameter is set) is expanded.Message is as follows:
For Client-〉Server (from user terminal to the streaming media server direction):
SET_PARAMETER?rtsp://10.71.141.31:554/avsync.mp4?RTSP/1.0
CSeq：1
Content-length：66
Content-type：text/parameters
x_key:5；x_opra_type:C_PL_Frozen_Moment；x-opra_param:40
By this message, the parameter that Client will carry out the multi-angle video business sends to Server, makes Server provide corresponding video signals according to this parameter.
For Server-〉Client (from streaming media server to the user terminal direction):
RTSP/1.0?200?OK
CSeq：1
Content-length：66
Content-type：text/parameters
x_key:5；x_opra_type:C_PL_Frozen_Moment；x-opra_param:40
By this message, Server confirms the parameter of the multi-angle video business that Client sends.
The meaning of each parameter was as shown in table 1 below during above-mentioned SET_PARAMETER described:
Table 1. parameter name, span and meaning
In the embodiment of the invention, the action type that streaming media server is supported, to operate the range of application of parameters needed and operation as shown in table 2:
The range of application of table 2. action type corresponding parameters and operation
The method to set up of parameter shown in above-mentioned table 1 and the table 2 and parameter; it is a kind of specific implementation of describing among the present invention; be not limited to protection scope of the present invention, can expand required parameter and parameter set-up mode as required in actual applications.
