The present invention relates to the image that a kind of display that is that 1st computing machine and transmit leg computing machine are possessed or that be connected with transmit leg computing machine shows, be presented at the technology on display that the 2nd computing machine and take over party's computing machine possess.
Background technology
In the demonstration of such as meeting, normally used is projector.When demonstrating, demonstration people will from the projector be connected with notebook computer etc. by required image projection to screen etc.The audience attended a meeting, while viewing projected image, listens to and watches the demonstration of demonstration people.
Summary of the invention
Invent technical matters to be solved
And when adopting above-mentioned conference method, if audience's distance projected image is far away, just may not see Chu's image.Especially in the picture containing in the situations such as less word, just this problem is easily produced.
Under the circumstances, in meeting, at least print a part using making a reservation for project to the image of audience sometimes and out provide as distribution data.Now, audience can listen to, watch demonstration, often bows on one side and sees distribution data.But when adopting this demenstration method, granting data needs to use paper.When listenership is many, make time that these distribution data spend, cost and provide times of these distribution data, cost all can't neglect.
For this reason, inventor thinks deeply.
Although notebook computer is popularized already, the mobile terminal such as smart mobile phone, flat board popularity is in recent years amazing.Achieve staff one already.
If demonstration people can be carried out demonstrating the image that the equipment such as used notebook computer show, be presented on these mobile terminals equally, the problems referred to above just can be readily solved.If the picture of the mobile terminal in audience's hand can show equally the image shown in the equipment such as the notebook computer that uses of demonstration people, even if so the projected image of audience and projector is apart from each other, also there will not be the problem not seeing projected image.
In addition, if the picture of mobile terminal can show equally the image shown in the equipment such as the notebook computer that uses of demonstration people, the distribution data providing papery is also just no longer needed.And if the view data that mobile terminal display shows can be preserved in the terminal by audience, the necessity so providing distribution data will be less.
If can realize this mechanism, then its purposes will be not limited to " substitute of past projector " under above-mentioned conference scenarios, such as, can use the equipment such as a notebook computer, send the information required for it to the spectators of viewing drama, concert or motion.It is equivalent to the television broadcasting system of simple and easy version " on a small scale, ", if can realize this mechanism, may can cause brand-new demand.
The object of inventor is that realizing one at least can use as " substitute of past projector ", and the mechanism of " on a small scale, the television broadcasting system of simple and easy version " can be used as, namely, the image that a kind of display that is that 1st computing machine and transmit leg computing machine are had or that be connected with transmit leg computing machine shows is provided, is presented at the technology on display that the 2nd computing machine and take over party's computing machine possess.
The technical method that technical solution problem adopts
Inventor, for solving above-mentioned problem, proposes following invention.
For simplicity, this case invention is divided into the 1st invention to the 3rd invention.
1st invention is a kind of communicator, is connected uses with transmit leg computing machine, and can pass through WLAN, communicate with multiple take over party's computing machine, described transmit leg computing machine has display or is connected with display, and described take over party's computing machine has display.
This communicator has: receiving element, receive the image that the 1st display shows, the data namely showing image from described transmit leg computing machine, described 1st display be described transmit leg computing machine have or display that described transmit leg computing machine connects; Compression unit, by the data of the image of a picture in described display image, the packed data namely becoming prescribed form based on the Image Data Compression of described display view data; Transmitting element, sending function while using WLAN, described packed data is sent to multiple take over party's computing machine in the regulation moment, described packed data can elongate by the described take over party's computing machine receiving described packed data, is shown to by described display image on display i.e. the 2nd display that this take over party's computing machine possesses.
Other inventions also have same case, but the communicator of the 1st invention is described above, is connected uses with transmit leg computing machine.Transmit leg computing machine is the computing machine that such as notebook computer etc. has display, or the computing machine that such as desktop computer etc. is connected with display.When demonstrating, transmit leg computing machine is equivalent to the PC operated by demonstration people.
The described communicator of 1st invention sends data to take over party's computing machine, these data are for being presented at the 2nd display by the image roughly the same with display image, described display image is the image that the 1st display shows, described 1st display be transmit leg computing machine the display that possesses or be connected with transmit leg computing machine, described 2nd display is the display that take over party's computing machine possesses, and is in most cases the article suitable with the mobile terminal mentioned in prior art.
Like this, comprise the communication system of transmit leg computing machine, take over party's computing machine and this case communicator, just can be used as " substitute of past projector " and use, and function can be played as " on a small scale, the television broadcasting system of simple and easy version ".
This communication system specifically, by transmit leg computing machine, communicator and multiple take over party's computing machine are formed, described transmit leg computing machine has display or is connected with display, described communicator is connected with described transmit leg computing machine and uses, described take over party's computing machine has display, WLAN can be passed through, communicate with described communicator, this communication system has, receiving element, from the image that described transmit leg computing machine reception the 1st display shows, namely the data of image are shown, described 1st display is that described transmit leg computing machine had, or the display that described transmit leg computing machine connects, compression unit, by the data of the image of a picture in described display image, namely the packed data of prescribed form is become based on the Image Data Compression of described display view data, transmitting element, sending function while using WLAN, described packed data is sent to multiple take over party's computing machine in the regulation moment, described packed data can elongate by the described take over party's computing machine receiving described packed data, described display image is shown on display i.e. the 2nd display that this take over party's computing machine possesses.
While the data of carrying out from above-mentioned communicator to take over party's computing machine send and use WLAN, sending function realizes.Numerous mobile terminals as take over party's computing machine all have reliable WLAN function, and therefore take over party's computing machine receives above-mentioned data is not difficult matter.In addition, with regard to communicator, as long as carry WLAN function, because the communication function of WLAN is supported one to one incessantly for it, the function that one-to-many sends data is also originally within specification, therefore data is sent to multiple take over party's computing machine also non-difficult matter.WLAN is Wi-Fi such as.Below invent too, communication function while WLAN is if Wi-Fi, acquiescence can carry out radio communication with 253 (when using 8 bit data as identification data) or 65533 (when using 16 bit data as identification data) computing machines simultaneously, communication distance, according to the performance of communication antenna, can support that tens of rice is to the communication of hundreds of meters.
And, also restricted when using WLAN and do not adopt specific communication method.Compared with the communication between transmit leg Computers and Communication device, the communication between communicator and take over party's computing machine is difficult to improve communication speed more, and this is also the same in wire communication.
The communicator of this case receives from transmit leg computing machine the data that namely image shown the 1st display show image, from these data, utilize compression unit to compress the data of the image of a picture and view data, view data after compression and packed data are sent to take over party's computing machine, above-mentioned 1st display be transmit leg computing machine have or display that transmit leg computing machine connects.Undoubtedly, the data volume of packed data is less than the data before compression.Like this, when utilizing WLAN to communicate, just can not there is too large problem in the delay of communication speed.Especially the display image used in demonstration, uses animation more.Now, if such as only when show image occur change time (such as, the change of cursor or mouse position on display image can be considered that display image does not change), just send data from the communicator of packed data to take over party's computing machine, then the communication speed restricted problem of WLAN does not exist substantially.
The known compression of images of the boil down to utilizing compression unit to carry out is such as JPEG compression or MPEG compression.In this, other inventions are also like this.
In addition, the communicator in the 1st invention and the communication between take over party's computing machine as mentioned above, utilize WLAN to carry out.This communication has very high compatibility with using the technology of UDP (UserDatagramProtocol: User Datagram Protoco (UDP)).UDP and to be listed as with it the communication protocol TCP (TransmissionControlProtocol: transmission control protocol) that people understand different, from dispensing device to receiving trap, just one to one, it is the agreement can carrying out one-to-many communication.In addition, although UDP exists the low difficult point of communication reliability, its communication speed is very fast.This is just being applicable to this case invention, although capacity diminishes after compression, but still needs view data to be sent to take over party's computing machine from communicator.In addition, especially this case is invented the most cases be used for when demonstrating, or when this case invention is used for the television broadcasting system of simple and easy version " on a small scale, ", must one-to-many communication, UDP is very convenient for realizing one-to-many communication.In view of this, the communication of above-mentioned WLAN is used preferably to use UDP.This point is for using each communication of required WLAN (may not be between communicator and take over party's computing machine sometimes, also may be the communication between transmit leg computing machine with take over party's computing machine) to be also the same in following invention.
As mentioned above, in the present invention, the data of display image are sent to communicator from transmit leg computing machine.
How the view data of display image is sent to communicator from transmit leg computing machine does not limit.Such as, can be sent by wired mode.As an example of wired transmission, can enumerate and use USB terminal (other also can enumerate wired lan, memory card interface, ExpressCard interface) to send data, other also can be enumerated and use simulation terminal (such as analog rgb terminal, HDMI terminal, DisplayPort, thunder and lightning Interface Terminal etc.) to send simulated data.Such as, the described receiving element of communicator can be USB terminal, and the USB terminal had with described transmit leg computing machine is connected.
The data being sent to communicator from transmit leg computing machine may be the simulated datas such as showing image.Transmit leg computing machine mostly is notebook computer or desktop computer, may be also mobile terminal, no matter be any, in most cases all has the modulating output terminal of the simulated data in order to output display image.The data of display image are the simulated datas of image, as mentioned above, are via modulating output terminal sometimes, are sent to communicator from transmit leg computing machine.Now, the described receiving element of communicator is exactly analog input terminal.
Now, simulated image data is exactly the data of continuous print frame.Extract the data of the image of a picture from this simulated image data after, it is exactly said view data in this case.View data both can be simulated data, also can be numerical data.At this moment, communicator in units of view data, by the Image Data Compression extracted, and can be sent to take over party's computing machine.But view data does not need each frame all to extract.In addition, the view data of extraction does not need all to be compressed to packed data, does not need all packed datas to be all sent to take over party's computing machine from communicator yet.As long as by the packed data of the requirement of image roughly the same with display image for display on the display of take over party's computing machine, be sent to take over party's computing machine from communicator.This is because, namely the data of the image of the frame extracting specified quantity the data of image are shown from continuous print frame data, it can be used as view data, then this view data all are compressed respectively and make packed data, again all packed datas are sent to take over party's computing machine from communicator, this information processing method is wasted least, and the possibility therefore adopted is high.Like this, in certain stage before sending packed data, from continuous print frame data, suitably fall frame to frame, then the restricted problem of the transmission speed using WLAN to produce will be less.
The described data of display image are intermittently sent to take over party's computing machine from transmit leg computing machine, and described Image Data Compression when each described transmitting element sends described packed data, can be become the packed data of prescribed form by described compression unit.This is roughly equivalent to the above-mentioned process carrying out suitably falling frame from continuous print frame data frame at transmit leg computing machine.The data being sent to communicator from transmit leg computing machine also can be above-mentioned view data.Now, the view data suitably selected will be sent to communicator from transmit leg computing machine.View data has the data of several frame ~ tens of frame in such as 1 second, no matter whether fixed intervals, as long as the data of the display image of every picture selected by predetermined distance, such as, can be whenever show image change time (such as, when showing PowerPoint (trade mark) picture as Co., Ltd. of Japanese Microsoft of demonstration software generic in the 1st display, as long as no operation animation process, before the transmission page, except cursor or mouse, show image can not change), the data of the display image of a picture of irregular selection.View data such as can be equivalent with the image be kept in frame buffer.
