Description

Projector interlocked with M2M module and its driving method {Projector interlocked with M2M module and method driving}

The present invention relates to a projector interoperating with an M2M module and a driving method thereof. More specifically, the present invention relates to a projector and a driving method thereof, which interoperate with an open M2M module that can be selectively connected to various M2M (Machine to Machine) devices.

M2M (M2M, Machine to Machine) is a remote management and control solution that supports communication between machines by connecting M2M module and device using wired / wireless communication method on a general wired / wireless network.

Various types of devices may be connected to the M2M module, and various applications may be driven according to the types of devices to be connected. For example, the M2M module has functions such as wideband code division multiple access (WCDMA), global system for mobile communication (GSM) / general packet radio service (GPRS) tri-band, and global positioning system (GPS), and has low / high speed data. It can be used for various applications such as communication, remote meter reading, location tracking and remote control.

On the other hand, recently, the promotion or presentation of products or ideas in various places frequently occurs. Various methods have been mobilized for this purpose, and among them, a projector is used to show an image and to explain. In general, a projector is a device that converts certain screen data into an image that can be recognized by people.

In particular, the spread of portable projectors that allow users to screen images anytime and anywhere is being actively promoted. The portable projector is connected to an external device through wired or wireless communication to receive screen data stored in the external device and output the screen data.

However, when the method of connecting to an external device is wired, there is an uncomfortable problem of connecting directly to the external device. In the case of wireless, in order to perform wireless communication between the external device and the projector, a projector capable of wireless communication is provided, and there is an inconvenience in that the external device and the projector must communicate while maintaining a certain distance.

In addition, the projector is conventionally faithful only to the projector's original function and does not have a separate communication function.

Therefore, a separate server is required for the projector to implement the call function. It is possible to talk to the other terminal through a specific server.

In addition, when the user wants to implement a call function in the projector by connecting a mobile phone or a laptop that can make a call, the projector cannot implement an independent function. Since the projector only performs the function of bypassing data from the mobile phone or laptop and outputting it to the screen, the function of the projector is also limited to the function that can be implemented in the connected external device.

In addition, a technology for mounting a projector function in a mobile phone has been proposed, but such a technology is determined during manufacturing of a terminal and fixedly operated in a specific portable terminal. Therefore, a user is limited to a specific terminal purchaser unless a new terminal is purchased.

In order to solve such a problem, the present invention provides a projector and a driving method for performing data communication in conjunction with the open-type M2M module detachably coupled.

According to one aspect of the invention, a projector is provided.

According to another feature of the invention, a method of driving a projector is provided. The method comprises: a method of driving a projector for projecting an image signal on a screen through a lens, the method comprising: (a) the projector being an M2M module, where the M2M module is selectively connected to a heterogeneous device and connected to a mobile communication network; Performing a communication function; (b) when a remote control signal for requesting data communication according to a user's key operation is received, generates a control command for requesting data communication among the predefined control commands for operating in conjunction with the M2M module and transmits the control command to the M2M module. step; And (c) the M2M module receiving image data received from the mobile communication network from the M2M module and projecting the image data on the screen, wherein the M2M module receives the control command from the projector and moves to the mobile communication network. Request data communication to establish a data channel.

According to an embodiment of the present invention, unlike the conventional projector merely implements a miniaturization function and there is no communication function separately, the projector can implement data communication, including video call and web browsing, in conjunction with the open MTM module coupled to be detachable. It becomes possible.
