Below in conjunction with preferred embodiment and preferred implementation, the present invention will be described.
Preferred embodiment 1
Fig. 4 is according to this preferred embodiment screen picture transmission system schematic diagram, as shown in Figure 4, this system comprises, transmitting terminal 42, first receiving terminal 44, second receiving terminal 46, wherein, transmitting terminal 42 function is equivalent to above-mentioned transmitting terminal 20, first receiving terminal 44 and the second receiving terminal 46 is equivalent to above-mentioned 30, do not repeat them here, below this system is described.
Transmitting terminal 42, first receiving terminal 44, second receiving terminal 46 is the network equipments that can be realized end-to-end communication by communication connection compositions one such as cellular network, wired connection, WIFI, bluetooths.
Transmitting terminal 42 needs the Image Sharing on self screen to show to the first receiving terminal 44 and the second receiving terminal 46 simultaneously.Than scene as such: user has taken a lot of photo with mobile phone, playback on mobile phone, the mobile phone at this moment needing the appreciation photo on mobile phone to adopt the mode of Screen sharing to be sent to two good friends is appreciated simultaneously.Adopt prior art can gather acquisition not picture frame composing images sequence in the same time for image that transmitting terminal 42 screen changes, the every two field picture in image sequence can carry out compression process (such as adopting the technology such as front and back frame difference, motion estimation and compensation, image compression encoding).
Fig. 5 is that as shown in Figure 5, the step that the method comprises is as follows according to this preferred embodiment screen picture transmission method flow chart:
Step S502, screen picture sequence is divided into parity frame by transmitting terminal 42, odd numbered sub-frames image is sent to successively the first receiving terminal 44, even subframe image is sent to successively the second receiving terminal 46;
Step S504, is transmitted to the second receiving terminal 46 by the odd numbered sub-frames image received when the first receiving terminal 44 receives odd numbered sub-frames image.Equally, when the second reception termination 46 receives even subframe image, the even subframe image received is transmitted to the first receiving terminal 44.
By above-mentioned steps, present successively after the odd even sub-frame images sequence restructuring that self just can receive by such first receiving terminal 44, second receiving terminal 46, complete Screen sharing.Compared with conventional transmission mode, when same network transmission speed, image compression method, the image of the transmission means energy fast transport Screen sharing of this preferred embodiment, thus be reduced in receiving terminal present time delay.
When receiving terminal also has more equipment, so the screen picture sequence of transmitting terminal can be divided into periodic sequence of subframes.Suppose there are 5 receiving terminals, so the 1st frame is sent to equipment one by transmitting terminal, and the 2nd frame sends to equipment two ..., the 5th frame sends to equipment five, Here it is one-period.At second period, 6 frames are sent to equipment one, the 7th frame sends to equipment two ..., the 10th frame sends to equipment five, and loop cycle like this sends.When any one receiving terminal receives the sequence of subframes from transmitting terminal, then the subframe of reception is sent other 4 receiving terminals.Certainly, the screen picture sequence of transmitting terminal can carry out periodicity not in accordance with the number of receiving terminal and divide, such as there are 6 receiving terminals, transmitting terminal is still that one-period is distributed to front 5 receiving terminals by 5 sequence of subframes above, in front 5 receiving terminals, each receiving terminal is transmitted to other 5 receiving terminals (comprising the 6th receiving terminal) after receiving the period subframe sequence image sent from transmitting terminal again, and that is the 6th receiving terminal receives only the sequence image that front 5 receiving terminals forward.The mode again forwarded between receiving terminal has multiple combination, is not limited to form described in the embodiment of the present invention.Such as, after xth subframe or sub-block are transmitted to y receiving terminal by an xth receiving terminal, by y receiving terminal, the xth subframe received or sub-block are transmitted to z receiving terminal.
By above preferred embodiment, can carry out efficiently transmitting fast for the transmission channel between compression or unpressed imagery exploitation multi-screen equipment.
Preferred embodiment 2
In the preferred embodiment, user needs the screen content of sharing users equipment under a territory net or home network environment, to share the courseware PPT demonstrated.Other 4 receiving equipments are connected end to end with the sending ending equipment formation of user.
Fig. 6 is the PPT sharing method flow chart according to this preferred embodiment courseware, and as shown in Figure 5, the step that the method comprises is as follows:
Step S602, the screen picture of collection is spatially carried out piecemeal in position by transmitting terminal, is divided into 4 pieces of subgraphs, and the 1st subgraph is sent to the first receiving terminal, and the 2nd subgraph sends to the second receiving terminal ..., the 4th subgraph is sent to the 4th receiving terminal;
To screen picture spatially position piecemeal, simply geometry division can be carried out.Such as a width rectangular image, 4 blocks of little rectangular images (such as image is divided into upper and lower two parts, more each for upper and lower two parts image left and right is split formation 4 pieces) can be divided into by the wide height of image.Also only the little rectangular image of 4 block length bar can be divided into by height or width.
Step S604, each in 4 receiving terminals receives from after the subgraph of transmitting terminal, received subgraph is transmitted to other 3 receiving terminals;
Step S606, each receiving terminal reassembles into complete screen picture after obtaining 4 subgraphs.In the sequence of image frames that transmitting terminal is follow-up, each two field picture repeats to carry out transmission process according to the method.
By above-mentioned steps, transmitting terminal can make full use of and send screen content with multiple interface channels of receiving terminal simultaneously.Receiving terminal, when receiving the new image from transmitting terminal, also utilizes and forwards with the sendaisle of other receiving terminals the screen picture received.Finally carry out restructuring at each receiving terminal and form complete screen picture or screen picture sequence, therefore can realize screen picture transmission fast, the method for this preferred embodiment can be carried out screen content fast and be shared, and improves Consumer's Experience.
Obviously, those skilled in the art should be understood that, above-mentioned of the present invention each module or each step can realize with general calculation element, they can concentrate on single calculation element, or be distributed on network that multiple calculation element forms, alternatively, they can realize with the executable program code of calculation element, thus, they can be stored and be performed by calculation element in the storage device, or they are made into each integrated circuit modules respectively, or the multiple module in them or step are made into single integrated circuit module to realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
