Briefly, after equipment connection is established by the direct-connected mode of WIFI in transmitting terminal/receiving end, user is in sending ending equipment Upper selection split screen display available function, and the transmitting terminal screen picture in receiving end shows the display position in equipment when selecting split screen display available It sets, after receiving device receives transmitting terminal setting information and confirms, sending ending equipment is by the multi-medium data of interception (audio-visual and figure Picture) be transferred to after compressed encoding receiving end show equipment show.

It holds and continues upper example, in the above embodiment of the present invention, receiving end must support connection, decoding, splicing and the ability shown；Tool Body requires as follows:

Multiple sending end connects reception ability: supporting more transmitting terminals to be connected to same receiving end, receiving end GO is supported same When connect with multiple P2P transmitting terminals；

Multipath decoding ability: Media Stream of the decoding from more transmitting terminals is supported；

Video frame splices ability: can will be spliced into a target image after the media stream from more transmitting terminals and show Show in the display equipment of receiving end.

And it is as follows to the specific requirement of transmitting terminal:

Support that split screen display available setting is carried out with receiving end to be negotiated；

It supports to select under more split screens in the display position for receiving end side；

Support that the split screen display available for receiving end is adapted to resolution ratio.

Preferably, preferably realizing simultaneous display function, transmitting terminal to reduce the time delay between transmitting terminal and receiving end It needs unanimously, then to reduce the time of coding/decoding, display efficiency is provided with the code/decode format of receiving end；Such as transmitting terminal with connect The code/decode format of receiving end is consistent with the direct-connected standard of WIFI, using H.264 coding mode.

Due to there is no information exchange between transmitting terminal each in the specific embodiment of the invention, therefore there may be two or more The identical conflict for leading to target area in target area of a transmitting terminal selection, then the embodiment of the present invention by receiving end end with it is each Information exchange between a transmitting terminal determines the target area not conflicted mutually, the method for specific receiving end further include:

First area determines step 14, interacts before generating the target image with each transmitting terminal and determines each The target area not conflicted mutually that transmitting terminal respectively selects.

Preferably, first area determines that step 14 includes:

First analyzing step 142 specifically includes:

Second receiving step 145 receives the region choosing in the carrying first object region that first transmitting terminal is sent Select request response；Wherein, it states in the second receiving step 145 and is included at least in regional choice request response by the first hair The span mode and the split screen block selected under the span mode that sending end determines, determine first object area by the split screen block Domain.

Region analyzing step 146 parses the region and chooses request response acquisition first object region

Second return step 147, the first transmitting terminal of Xiang Suoshu return to target area response message chosen successfully.

And second data acquisition step 21 of corresponding transmitting terminal specifically includes:

Second sending step 211, the first transmitting terminal send to receiving end and inquire whether the receiving end supports span mode Inquiry message；

4th receiving step 212 receives the split screen mould that the carrying that the receiving end returns is used to select for the first transmitting terminal The regional choice request message of formula, and first object region is determined according to the region request message；

Third sending step 213, the regional choice request response for sending the carrying first object region to receiving end disappear Breath；Wherein, the split screen mould determined by transmitting terminal is included at least in the third sending step in regional choice request response Formula and the split screen block selected under the span mode determine first object region by the split screen block.

5th receiving step 214 receives the receiving end and obtains the first mesh from the regional choice request response The target area response message chosen successfully returned behind mark region.

As shown in Figure 10, such as the span mode of above-mentioned transmitting terminal determination is 4 split screens, is selected under the span mode Split screen block is position 1, then position 1 is first object corresponding with transmitting terminal position.Specifically, above-mentioned span mode is specifically Refer to several span mode, such as 2 split screens, 4 split screens etc., the split screen block selected under the span mode refers on the screen of receiving end The specific location of display；It is fixed in the position of the split screen block if being provided only with a kind of split screen mode under a span mode；It is no Then the position of the split screen block is then determined by split screen mode；When a span mode has at least two different split screen modes, The method of the transmitting terminal of the embodiment of the present invention further include: split screen mode determines step, when the split screen mould that preceding transmitting terminal determines When formula is arranged at least two split screen mode, the split screen mode under the span mode is selected by the preceding transmitting terminal.I.e. Split screen mode under span mode is selected by first transmitting terminal, and after the first transmitting terminal has selected split screen mode, above-mentioned point It is fixed for shielding the position of block.Preferably, receiving end screen can be placed in a seat in order to clearly describe the split screen mode Its split screen region is indicated using coordinate value in mark system；Or it is arranged for the split screen mode under different span mode corresponds in advance Split screen region, transmitting terminal selects it to need the split screen region of selection.

3 kinds of split screen modes are included at least by taking 4 split screens as an example, as shown in Figure 10, the first: lateral split screen, such as Figure 10 b institute Show, can be adapted for the game of race class；Second: longitudinal split screen can be adapted for the game of aircraft class as shown in figure l0c； The third split screen mode as shown in Figure 10 a, applies in general to play picture or video of separate sources etc. simultaneously.Of the invention real It applies in example, transmitting terminal must determine its span mode and split screen mode according to its actual conditions, wherein the span mode need to be received Hold supported span mode, the span mode supported in inquiry response messages comprising receiving end.

Since at least two transmitting terminals and a receiving end being arranged in the embodiment of the present invention, if therefore each transmitting terminal press Span mode and split screen mode are selected according to its actual conditions, the span mode or split screen mode received when receiving end does not connect simultaneously Receiving end, which not can determine that, carries out split screen display available in such a way which transmitting terminal determines；Therefore in practical application of the invention, work as head After a transmitting terminal (generally first transmitting terminal) determines its span mode, when posterior transmitting terminal sends inquiry, receiving end is only Return to the span mode that preceding transmitting terminal determines；Specifically, end side is received when first transmitting terminal is first transmitting terminal, The span mode in regional choice request message in first return step is all points that the receiving end is currently supported Screen mode；

Correspondingly, sending area of the end side when first transmitting terminal is first transmitting terminal, in the 4th receiving step All span mode that domain selects the span mode in request message currently to support for the receiving end；

Special, if span mode is set single screen projection mode by posterior transmitting terminal, the latter's priority principle is followed, The transmitting terminal currently connecting with receiving end disconnects, and receiving end carries out single screen projection to the posterior transmitting terminal；Or it abides by The former priority principle is followed, the transmitting terminal currently connecting with receiving end keeps connecting, and receiving end sends gravity treatment response to transmitting terminal, The receiving end for not having transmitting terminal to connect to other again from transmitting terminal, which initiates the connection and carries out single screen, to be shown.

Above-mentioned two principle any selection can may also set up prefixed time interval and be used alternatingly according to the actual situation, such as right For the receiving end for launching real-time news, up-to-date information need to be shown using the latter's preferential principle in time；Or for For needing the advertising pictures shown for a long time, generally advertising information is prevented to be replaced using the former preferential principle；Or it is directed to Need to every a period of time replace a content billboard for, such as this be for a period of time in 2 days, 2 days the billboard use before Person's preferential principle, the billboard uses the latter's preferential principle after 2 days, both ensure that in advertisement display time do not replaced in this way Content is changed, advertisement can be replaced when advertisement expires in time by also ensuring.

In practical application of the invention, in order to avoid the project content of receiving end is replaced always, it is excellent to generally use the former First principle, but in a meeting using split screen projection one product of description or a scheme when, it is general preferential using the latter Principle, convenient for allowing participant to further appreciate that subsequent schedule.

It should be noted that if receiving end does not support that span mode, the first return step 144 are that the transmitting terminal returns It refers to show that receiving end does not support the inquiry response messages of span mode and terminates process；Due to the embodiment side of the embodiment of the present invention Formula is just able to achieve in the case where span mode is supported in receiving end, therefore is not retouched specifically to the receiving end for not supporting span mode It states.

Meanwhile in order to support split screen function, it is direct-connected to WIFI in real time streaming transport protocol RTSP M3 and M4 message in Message parameter expanded.Specifically, regional choice request message described in the display processing method of receiving end, inquiry disappear Breath, inquiry response messages realize that request is selected in the region based on the M3 message in the real time streaming transport protocol shown for WIFI Response message, operating mode notification message and operating mode push-notification-answer message are based on the real-time streaming transport association shown for WIFI M4 message in view is realized；Simultaneously in the display processing method of transmitting terminal, the regional choice request message, is ask at inquiry message Ask that response message is realized based on the M3 message in the real time streaming transport protocol shown for WIFI, the region selects request response and disappears Breath, operating mode notification message and operating mode push-notification-answer message are based in the real time streaming transport protocol shown for WIFI M4 message is realized.

The expansion of message parameter in M3 the and M4 message of real time streaming transport protocol RTSP in specifically direct-connected to WIFI It is as shown in the table:

It should be noted that only needing a transmitting terminal to connecing in the multiple transmitting terminals for sending audio file to receiving end Receiving end sends audio file, other transmitting terminals only send video file；If there is two or more transmitting terminals transmits sound When frequency file, then receiving end plays the sound of two-way or multichannel synthesis；Which transmission sound how negotiated about multiple transmitting terminals Sound is not emphasis of the invention, and this is not described in detail here.

It is directed in the second of the determination method of the above-mentioned target area not conflicted mutually and carries out in another embodiment of the present invention It is described in detail, i.e., as the complete or collected works that the optional target area is all target areas, when using the former mode of priority, the display Processing method further include:

First judgment step 31, judges whether the first object region is selected；

Reselection request step 32 is selected when the first object region is selected to prior to first transmitting terminal Select the second transmitting terminal sending zone reselection request message in the first object region；

Second analyzing step 33 receives and parses through the region reselection request response message that second transmitting terminal returns, from Middle the second target area for obtaining second transmitting terminal and reselecting.

Correspondingly, the method for transmitting terminal further include:

Gravity treatment receiving step 41 receives the receiving end when the first object region is selected again by other transmitting terminals The region reselection request message of transmission；

Request is selected in gravity treatment response of step 42, the region that the receiving end Xiang Suoshu returns to the second target area that carrying reselects Response message enables receiving end after receiving the region reselection request response message, and parsing obtains second mesh Mark region.

When using the latter's mode of priority, the display processing method further include:

Conflict and determine step 34, after new transmitting terminal is added, is passed through according to the transmitting terminal being newly added with receiving end The third target area that the direct-connected mode of WIFI selects after connecting determines in the target area selected at least two transmitting terminal The conflict transmitting terminal to conflict with the third target area；

Break step 35 is connected, disconnects with after the connection of the transmitting terminal that conflicts, returns to the first data acquisition step.Its In, depending on the selection according to the actual situation of the former mode of priority or the latter's mode of priority, it is not specifically limited herein, specific feelings Condition with above-mentioned the former is preferential or the latter's priority principle is consistent.

Specifically, if there is new sending ending equipment accesses, and having selected other current terminals under span mode Non-selected position, then the terminal screen can correctly project to the corresponding position of receiving device；(process as shown in figure 5, its Selected position WIFI direct-connected screen position is non-selected for the transmitting terminal of currently attached receiving end in middle M3 response OK Position)；Alternatively,

Under span mode, if there is new sending ending equipment accesses, and select other current terminals selected Position, then the terminal screen can correctly project to the corresponding position of receiving device, select before the terminal of the position with Receiving device disconnects (the latter's priority principle)；(process is as shown in figure 5, wherein M3 responds selected position in OK The position that WIFI direct-connected screen position is had been selected by the transmitting terminal of currently attached receiving end).Wherein, it transmitting terminal and connects The disconnection process of receiving end is illustrated in fig. 6 shown below: receiving end active transmission M8 message indicates that transmitting terminal disconnects to transmitting terminal.And Single screen projection, the then terminal currently connecting with receiving end are set as if there is new sending ending equipment accesses, and by span mode It disconnects, such as in Fig. 5, in the GET_PARAMETER message of M3, the direct-connected more split screens of WIFI support=1, i.e. single screen is shown When, receiving end need to send the connection of message disconnection and other transmitting terminals.

Due to the limitation of existing WIFI direct-connecting technology, the number for the transmitting terminal that a receiving end can connect has a upper limit (upper limit is not especially limited), then the method also includes:

Second judgment step 36, when receiving the probe request message that new transmitting terminal is sent, judging whether can be with More transmitting terminals establish connection；

Refusal step 37 refuses institute when that can not establish connection with more transmitting terminals in probe requests thereby response message State new transmitting terminal.

Specifically, there are two types of methods for group leader's negotiation in another embodiment of the present invention:

First group long selection step 51, carries in probe request message or probe requests thereby response message and connects described in an instruction Receiving end needs the instruction information as group leader, and the receiving end is made to become group leader；I.e. without negotiating, autonomy group leader；Receiving end Equipment is in equipment discovery phase by the group user of the P2P capabilities attribute in probe request message or probe requests thereby response message The domain (Group Owner) is set as 1 (i.e. instruction receiving end oneself is group leader)；It is proposed in the embodiment of the present invention without negotiation When connection is established in mode, transmitting terminal each in this way and receiving end, does not need to hold consultation every time, save time and unnecessary step Suddenly.

Alternatively, second group long selection step 52, after establishing connection at least two transmitting terminal, with described at least two A transmitting terminal is negotiated, and group leader is become；That is GO negotiates, and receiving device completes device discovery procedure with sending ending equipment with laggard The GO intention value of oneself is set as 15 always by row GO negotiations process, receiving end, using indicate oneself must be as group leader；Wherein, The principle of GO negotiation mechanism is as shown in Figure 7, wherein X1 is group leader's intention value of P2P equipment 1, and X2 is that the group leader of P2P equipment 2 anticipates Map values.

It is illustrated by taking the split screen display available process between multiple mobile phones and television set as an example below:

It is used when establishing connection between mobile phone 1 and television set and determines television set for group without negotiation mode or GO negotiation mode After length, the connection establishment process of mobile phone 2, mobile phone 3 ... mobile phone N and television set is same as described above；When TV pusher side can not be again When receiving more mobile phones, 1 is set by the P2P group limit in the group ability of P2P IE

During mobile phone 2 and television set carry out equipment discovery and connect, the detection sent by the TV pusher side received The information carried in request message or probe response message, it can be found that other and the associated P2P facility information of the GO.(tool The process of body utilizes P2P agreement 3.2.4, and this is not described in detail here)

It, can be by being 1 by the bit position when TV pusher side can not receive the connection of more equipment as group leader again.

And for displaying target image better in display module, point of the corresponding source images of each source image data Resolution is determined by corresponding transmitting terminal according to the resolution ratio of the display module and the display area size of the source images.Send out Sending end equipment can be according to the resolution ratio of display module in receiving device and the facilities adjustment transmitting terminal hair of more split screens The resolution sizes sent, to reach optimal display effect and efficiency of transmission.
