Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
According to the embodiment of the present invention, provide a kind of method of live instructor in broadcasting, shown in Figure 1, the method flow process is as follows:
Step 101: obtain instructor in broadcasting's data, these instructor in broadcasting's data comprise the data of physical machine position collection and/or the data of virtual seat in the plane collection.
In the embodiment of the present invention, physics seat in the plane specifically comprises the audio and video acquisition devices such as video camera or USB camera, and a more than physics seat in the plane.
The Data Source of virtual seat in the plane has three kinds: local video data, image data and online web data.Therefore the data obtaining virtual machine collection in step 101 specifically comprise steps A 1-A3:
Steps A 1, obtain local audio, video data; And/or
Steps A 2, obtain local image data; And/or
Steps A 3, obtain online web data.
Wherein, virtual seat in the plane can obtain in above-mentioned three kinds of data one or more, specifically determine according to actual scene.
Step 102: carry out editing and processing to instructor in broadcasting's data, determines live TV stream data.
Video is made up of continuous print image one by one, in the embodiment of the present invention, video keying technology is adopted to carry out editing and processing to instructor in broadcasting's data, video keying technology is exactly removed by the partial pixel satisfied condition in the every piece image in video, then the imaging importing of remainder in target video image.Step 102 specifically comprises:
Step B1, dynamic special effect processing is added to instructor in broadcasting's data;
Step B2, interpolation LOGO process is carried out to instructor in broadcasting's data;
Step B3, the process of interpolation captions is carried out to instructor in broadcasting's data.
Concrete, for the dynamic special effect processing of interpolation, special efficacy video is set to a, and special efficacy background colour is set to black.The video image of instructor in broadcasting's data is set to b.The process of video keying superposition is: scan image b, pointer is navigated at the beginning the position that image a starts to superpose, the pixel value of scan image a one by one, if ater is then skipped, if not then taking out this pixel value, the pixel value taken out is replaced the pixel value of correspondence position in image b from image a, entire image a is scanned, the process of scratching picture superposition also just completes, and finally forms composograph.Load if a is special efficacy, then special efficacy is a qualified video, and multiple scanning a then realizes dynamic special efficacy effect.If LOGO loads, then a is set to qualified picture.
For the process of interpolation captions, set up two color bitmaps, then on this bitmap, draw character content in internal memory, so obtain one piece of lattice information of character content, such as 0 represents background, and 1 represents prospect character.In the process of reality superposition, the pixel of picture frame assigned address is done corresponding with the pixel bit of character pattern, if the pixel place value of character pattern is 0, then keeps the pixel value that picture frame is corresponding constant, if be 1, then pixel value corresponding for picture frame is replaced with default character color value.
Step 103: the instantaneous transmission ability according to transmission link is shunted live TV stream data, and the live TV stream data block interpolation sequence number mark for obtaining after shunting.
In the embodiment of the present invention, transmit live TV stream data in the mode of multilink parallel transmission (Multi-Path Transmission, MPT).MPT is the expansion to conventional TCP protocols, is added between application layer and transport layer.
The same with conventional TCP, MPT also needs to shake hands to connect, and also needs three-way handshake (three-way handshake), SYN (synchronous, handshake), SYN ACK, ACK (Acknowledgement, acknowledge character).MPT client sends and is arbitraryly connected to service end, carries out shaking hands being connected with service end.In any one MPT transmits, capital has a unique MPTID to carry out transport stream differentiation, and this ID can be produced by client, and this ID determines in handshake procedure, also can consult 32 random numbers as auxiliary detection, this random number only survived in the life cycle of MPT transport stream simultaneously.After consulting MPTID and random number, a MPT transmission completes with regard to initialization.
When MPT transmission allows to break in a transport network, continue to keep transmission state, be mainly used in the environment of network signal instability.Need initiatively to close so the transmission of MPT connects, and can not close because transport layer is abnormal.Initiatively closing can be that client is initiated, and also can be that service end is initiated.Connect the same with conventional TCP, after receiving FIN (Finish, terminate) signal, send FIN ACK, both sides will be closed simultaneously, or time-out is closed automatically completely.
In the embodiment of the present invention, because the transport stream of MPT can comprise multiple transmission link, and the carrying transmittability of each transmission link is not identical, therefore needs to shunt live TV stream data according to the instantaneous transmission ability of transmission link; Meanwhile, dynamic detection transmission link, adds in real time or removes transmission link.After detecting new transmission link, this new transmission link automatic powder adding is added in transfer of data up till now and go, and dynamic assignment live TV stream data again, to make live TV stream data fastest to reaching destination address.
Also be added with sequence number mark in live TV stream data block, can sort to live TV stream data block according to this sequence number mark, thus obtain original live TV stream data.

It should be noted that, the MPT agreement that the embodiment of the present invention provides is application layer protocol, instead of kernel protocol stack, without the need to etc. operating system support, can directly apply.
Step 104: live TV stream data block is dispersed in different transmission links, is sent to destination address in the mode of multilink parallel transmission.
Wherein, this destination address not only comprises server address, can also comprise end address, family.Namely can series-connected transmission between client, using the input of the output of customer end A as customer end B, thus multiple client can deal with data simultaneously, increases work efficiency, and achieves the diversity transmission of audio/video flow, transfer and process technically.
Preferably, before step 104, also comprise: buffered is carried out to live TV stream data block, determine buffered data resource.
The live director method that the embodiment of the present invention provides supports that time delay is play, and namely when determining live TV stream data, after preset time period, transmits this live TV stream data.Wherein, this preset time period can be arranged by system default, also initiatively can be arranged by user.
In the embodiment of the present invention, before transmission live TV stream data, can buffered be carried out, form buffered data resource.Because network quality problem thus can not ensure that network can use at any time, but the collection of live TV stream data and generation can not be interrupted because of the instability of network quality, by determining buffered data resource before sending, the recording of live TV stream, editor etc. can be absorbed in, and not need to pay close attention to network quality.When occurring that power-off or other abnormal conditions cause network interruption, transmission can stop; After network recovery, automatically can also recover data by buffered data resource, automatically can resume according to buffered data resource simultaneously, avoid loss and the dislocation of live TV stream data.
Buffered data resource is transparent relative to user, and user does not need too much to pay close attention to buffered data resource; Also allow user to carry out some special operations to buffered data resource simultaneously, such as stop to resume.
