Screen projection method for paying connection between platforms

The present invention relates to a connection method between a plurality of platforms, and more particularly to a method of payment connection between a plurality of platforms.

In recent years, the electronic industry is prevalent, and various electronic devices are ubiquitous in the general public life. Users can not only use electronic devices to perform various entertainments, such as playing videos or executing games, but also the convenience of electronic devices. Increase work efficiency.

The functions that an electronic device can achieve, in addition to relying on its powerful hardware, need to be matched by software, such as playing a movie, which is achieved through the playback software of the movie. In general, users can purchase paid software or download free software over the Internet, depending on the marketing strategy of the software developer. However, when the functions performed by the software simultaneously span multiple electronic devices, the payment mechanism of the software needs to be carefully formulated by the software developer.

Taking a screen projection program as an example, the screen projection program can transmit the multimedia material played on the screen of a first electronic device to the screen of a second electronic device through the network system for playing. In this case, a transmission screen projection program (hereinafter referred to as a transmission end program) needs to be installed on the first electronic device for externally The second electronic device needs to be installed with a receiving screen projection program (hereinafter referred to as a receiving end program) for receiving data and processing it.

From the perspective of the software developer, if the above-mentioned transmitter and receiver programs are open to users for free download, although the user will not have any inconvenience in using it, the software developer cannot charge any fees. The rights of software developers. Furthermore, if both the transmitting end program and the receiving end program are required to pay for the purchase, the user has to pay twice, which is quite unreasonable. Therefore, the software developer can set one of the transmitter program and the receiver program to pay for the purchase, while the other party can use the free version of the program to establish the connection.

At present, there are a variety of display devices on the market (such as smart TVs, projectors, and expansion devices that can support the screen projection function). In order to facilitate the user to use the above-mentioned screen projection function, software development will be requested before the original factory is produced. The receiver program is built into it. Thereby, after the user purchases the display device, the electronic device equipped with the transmitting end program can be connected to the display device for screen projection. However, how to negotiate the cost with the manufacturers of these display devices is a problem that software developers need to overcome.

Some manufacturers are reluctant to increase the manufacturing cost of the display device. Therefore, it is hoped that a free receiver program can be built in, and then the user can purchase and install a paid transmitter program for screen projection; some manufacturers are willing to pay a fee for the display device. A pay-per-use receiver is built in to allow users to connect to the display device through a free delivery program. However, how much the vendor should pay is reasonable, and how much software developers should open up to the built-in receiver (for example, which types of platforms can be used to support the software), all for software developers. Thinking about the problem.

For example, if the display device has a built-in free receiver program, it must be ensured that the user is connected to a paid transmitter program, otherwise the software developer cannot charge any fee; For the paid receiver program, you must avoid the user to purchase the paid transmitter program to connect, so as to avoid the unreasonable situation that the software developer charges twice. In addition, if the display device is built-in, it is paid. The receiver program, and the user also uses the free receiver program to connect, it is still necessary to determine whether the receiver program can support the transmitter program used by the user.

As mentioned above, the current market should provide an accurate judgment mechanism that can satisfy both software developers, manufacturers, and users to ensure the interests of the three parties and avoid unreasonable payment behavior.

The main purpose of the present invention is to provide a method for paying a connection between a screen projection program and a platform, which can ensure that one of the transmitting end software and the receiving end software used by the user is a paid version, and can also ensure the user. It is not necessary to purchase the paid version of the transmitter software and the receiver software at the same time, so as to protect the rights of both the software developer and the user.

To achieve the above object, the present invention mainly installs a transmitting end software in a transmitting end device of a projection source, and installs a receiving end software in a receiving end device of a projection destination. If the transmitter software is a paid version, the transmitting device can establish an unrestricted connection with any receiving device for screen projection; if the transmitting software is a free version, it is necessary to further confirm whether the receiving software is a paid version. To determine whether there is a restricted connection or an unrestricted connection between the transmitting device and the receiving device.

Another main object of the present invention is to provide a method for paying a connection between a screen projection program and a platform. When a third party manufacturer builds the receiving end software into the receiving end device, the third party manufacturer can pay the software developer according to the third party manufacturer. The amount is used to set which platforms the receiving end software can support. In this way, it can help software developers and third-party vendors to discuss the mode of cooperation.

In order to achieve the above object, the present invention further installs a transmitting end software in the transmitting end device of the projection source, and installs a receiving end software in the receiving end device of the projection destination. If the software of the transmitting end is a free version and the receiving end software is a paid version, it is necessary to further confirm whether the software of the paying receiving end supports the platform for using the free transmitting end software, thereby determining that the transmitting end device and the receiving end device can be established. Limited or unrestricted connections.

The screen projection program mainly transmits a screen of a transmitting end device (such as a mobile phone) to a receiving end device (for example, a smart TV) via a network system, and plays it through a screen of the receiving end device, thereby achieving a similar screen. Project the past effect. The utility of the present invention in comparison with the prior art is that the payment transmitting end software can assist the transmitting end device to project the screen to any receiving end device, and the user does not need to separately purchase the payment receiving end software, so that the user's rights can be effectively protected. . Furthermore, if the free-end software is installed in the transmitting device of the projection source, and the free-receiving software is installed in the receiving device of the projection destination, the user can only perform limited connection. In this way, it is ensured that at least one of the two devices must purchase and install a paid version of the software to protect the rights of the software developer.

DETAILED DESCRIPTION OF THE INVENTION A preferred embodiment of the present invention will be described in detail with reference to the drawings.

Referring first to the first figure, a block diagram of a system in accordance with a preferred embodiment of the present invention. The method for paying for the connection between the screen projection programs of the present invention is mainly applied between at least one transmitting end device 1 and at least one receiving end device 2, and the transmitting end device 1 and the receiving end device 2 are respectively provided with one The screen projection program can use the screen projection program to project the screen of the transmitting device 1 to the screen of the receiving device 2 through the network system. The difference is that the screen projection program installed in the transmitting end device 1 is a transmitting end software 10, and the screen projection program installed in the receiving end device 2 is a receiving end software 20.

As shown in the first figure, the transmitting end software 10 can be divided into a payment transmitting end software 110 or a free transmitting end software 120. The user can purchase the paid transmitting end software 110 from the software developer and install it on a first transmitting end. In the device 11, the user can download the free delivery software 120 for free through the network and install it in a second transmitting device 12.

The receiving end software 20 can be divided into a payment receiving end software 210 and a free receiving end software 220. The user can purchase the payment receiving end software 210 from the software developer and install it in a first receiving end device 21; The user can also download the free receiving software 220 for free through the network and install it in a second receiving device 22. It is worth mentioning that the receiving device 2 usually has a display screen larger than the transmitting device 1 , for example, a smart TV or a large-sized notebook computer. Yes Therefore, the receiving end software 20 can be an embedded receiving end software 230, which is installed in the receiving end device 2, for example, the third receiving end device 23 is built in the original factory, so that the user does not have to In addition, purchase and installation can greatly enhance the convenience of users.

Please refer to the second figure at the same time, which is a system architecture diagram of a preferred embodiment of the present invention. In general, the transmitting device 1 can be a personal computer (PC), a laptop, a tablet, a smart phone, etc., and is not limited. The transmitting device 1 can mainly execute a multimedia file through an internal controller, such as playing a movie or executing a game, etc., and transmitting the screen of the transmitting device 1 to the outside through the screen projection program installed internally.

The receiving device 2 can be mainly a smart computer (Smart TV), a personal computer, a notebook computer, a tablet computer, a smart mobile phone, etc., and the receiving device 1 is mainly received through the screen projection program installed internally. The transmitted data is played on the screen after being decompressed and decoded. It is worth mentioning that if the user wants to transmit the screen of the transmitting device 1 to a device that cannot run the program itself, for example, a projector 3, the receiving device 2 can be an expansion device. The projector 3 is connected sexually. The expansion device internally installs and executes the receiving end software 20, and the expansion device receives the data transmitted by the transmitting end device 1, and after decompressing and decoding, transmits the decoded image and sound to the projector 3, thereby Projection externally.

An advantage of the present invention is that if the screen projection program installed in the transmitting end device 1 is a paid version, that is, the paying transmitting end software 110, the transmitting end device 1 can be unlimitedly connected to the receiving end device of any platform. 2 establish a connection, and then perform a screen projection action. For example, the first transmitting end device 11 in the first figure may be arbitrarily connected to the first receiving end device 21, the second receiving end device 22, and the third receiving end. Device 23 establishes an unrestricted connection.

If the screen projection program installed in the transmitting device 1 is a free version, that is, the free transmitting software 120, the free transmitting software 120 needs to check the receiving end software 20 before the connection is established. version of. If the receiving end device 2 of the projection destination is installed with the free receiving end software 220, the transmitting end device 1 and the receiving end device 2 can only establish a limited connection (described later in detail). On the other hand, if the receiving device 2 of the projection destination is installed with the paying receiver software 210, the transmitting device 1 and the receiving device 2 can establish an unrestricted connection. And, after the connection is successfully established, the screen projection operation is performed.

It is worth mentioning that the software developer can determine, according to the selling price of the payment receiving end software 210, which of the transmitting end software 120 the paid receiving end software 210 can support. Please refer to Table 1 for the support diagram of the receiver software 20.

If the price of the receiving end software 20 is relatively cheap, for example, the A software in Table 1 is priced at 0.99 US dollars, the software developer can set the paying receiving end software 210 due to the low selling price of the A software (here is A software internal flag to limit the A software can only support the free transport software 120 of the Windows platform. When the Mac platform is free When the fee transmitting software 120 is to be connected with the A software, the free transmitting software 120 needs to further determine whether the A software supports the Mac platform after determining that the A software is a paid version. As shown in Table 1, the free delivery software 120 of the Mac platform will not be able to establish an unrestricted connection with the A software. However, Table 1 is only a preferred embodiment of the present invention and should not be limited thereto.

As shown in the B software and C software in Table 1, software developers can also support B-software and C software to support a variety of platforms. For example, as shown in Table 1, B software can support the free delivery software 120 on Windows and Mac platforms, but cannot support Android, iOS and Black Berry platforms; for example, C software can support this free transmission on Mac and iOS platforms. End software 120, but can not support Windows, Android and Black Berry platform. The above support for the use of the platform can be set by the flag inside the receiving end software 20, but is not limited.

As described above, the receiving end software 20 can also be the embedded receiving end software 230, for example, when the smart TV is produced, that is, the embedded receiving end software 230 is built in. Depending on the means of sales, the TV manufacturer may contract with the software developer to determine which embedded receiver software 230 to be built into the smart TV.

The TV manufacturer can pay a reasonable price at the time of signing, whereby the software developer can set the embedded receiver software 230 to support the free transmitter software 120 of all platforms, that is, D as shown in Table 1. software. In this way, after the consumer purchases the smart TV, the transmitter device 1 of any platform can be used to establish an unrestricted connection to project the screen onto the smart TV. On the other hand, if the vendor does not pay the fee, the software developer can set the embedded receiver software 230 to be unable to support the free transmitter software 120 of any platform, that is, the E software as shown in Table 1. As a result, consumers still need another after purchasing the smart TV. The payment transmitter software 110 is purchased and installed in the transmission device 1 to perform unlimited connection with the smart TV.

Please refer to FIG. 3A and FIG. BB simultaneously for the first flowchart and the second flowchart of a preferred embodiment of the present invention. First, the transmitting end device 1 and the receiving end device 2 request to establish a connection (step S300), wherein the request for the connection may be initiated by the transmitting end device 1 or may be initiated by the receiving end device 2, which is not limited. Then, if the payment transmitting end software 110 is installed in the transmitting end device 1, the transmitting end device 1 can directly establish a connection with the receiving end device 2; and if the transmitting end device 1 is installed, the free device is installed. The transmitting end software 120 needs to check the version of the receiving end software 20 installed by the receiving end device 2 by the free transmitting end software 120 (step S302).

After step S302, the free delivery software 110 determines whether the receiving software 20 is a paid version (step S304). If the receiving software 20 is a paid version, that is, the paid receiving software 210, the free The transmitting end software 120 needs to further read the flag inside the payment receiving end software 210 (step S306), so that it is determined by the flag whether the payment receiving end software 210 supports the usage platform of the free transmitting end software 120 (step S308). ). If the payment receiving end software 210 can support the usage platform of the free delivery end software 120, the transmitting end device 1 and the receiving end device 2 can establish an unrestricted connection (step S310), and after successfully establishing the connection The screen projection operation is performed (step S312).

However, if it is determined in the step S304 that the receiving end software 20 is a free version, or the receiving end software 20 is a paid version, it is determined in the step S308 that the paying receiving end software 210 cannot support the free transmitting end software 120. To use the platform, you need to skip to the steps shown in Figure B.

As described above, the transmitting device 1 and the receiving device 2 can be restricted. The connection is made (step S320), and after the connection is successfully established, a screen projection operation is performed (step S322). There is a restricted connection between the transmitting end device 1 and the receiving end device 2, so the free transmitting end software 120 needs to immediately determine whether the connection reaches a restriction condition (step S324). The limitation may be, for example, a limitation of the connection time. For example, when the connection time reaches 5 minutes, it is considered that the restriction condition has been reached, but this is only an example and should not be limited thereto.

If the connection has not reached the restriction condition, the transmitting end device 1 and the receiving end device 2 can continue to perform screen projection, and when the connection reaches the restriction condition, the connection between the two devices 1 and 2 is restricted. Line (step S326). For example, the connection between the transmitting device 1 and the receiving device 2 can be forcibly disconnected, or a payment reminding message is displayed on the screen of the transmitting device 1 and/or the receiving device 2 to remind the user to purchase The paid version of the software, etc., but not limited.

It is worth mentioning that, by the above steps, it has been ensured that at least one of the transmitting device 1 and the receiving device 2 must purchase and install a paid version of the software. Therefore, even if the transmitting end device 1 or the receiving end device 2 uses a Windows (Windows) platform, there is no need to force the user to enter a registration code or surf the Internet for authentication when installing the software, so that the use can be greatly reduced. Inconvenience.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, equivalent changes to the scope of the present invention are included in the scope of the present invention. Bright.
