Description

Wireless data transmission device for presentation device and method thereof {Wireless Data Transmission Device for Presentation Devices and Method}

The present invention relates to an apparatus and a method for transmitting data wirelessly to a presentation device. More particularly, the present invention relates to a wireless receiving apparatus installed in a presentation device, and a transmitting apparatus and method for wirelessly transmitting control data, voice data, and the like used by a presenter.

Computers, beam projects, laser pointers, and the like are provided for presentations while projecting presentations on a screen, and a user or presenter has a lot of inconvenience in making a presentation while controlling the equipment. In particular, in order to ensure the efficiency of the presentation and the accuracy of communication, the use of a microphone is often required. However, there is a problem that the use of the microphone is difficult because the microphone and the installed acoustic equipment are not compatible with each other. In order to solve this problem, wireless microphones may be used, but in reality, many school facilities do not have equipment for transmitting and receiving wireless microphones that are carried by the user at each classroom. In addition, for presentations, users had to carry wireless microphones, laser pointers, wireless keyboards, and even presentation materials and lecture materials all in their hands. There was a problem.

An invention for solving the above problem is disclosed in Korean Patent Laid-Open Publication No. 10-2009-0005881 (Portable Device for Presentation and Method of Executing Voice Output and Control Command of the Portable Device).

The present invention relates to a presentation portable device and a method of executing a voice output and a control command of the portable device. The present invention relates to an encoding unit for encoding a voice signal of a user input through a voice input unit, and wirelessly converts voice data passed through the encoding unit. A wireless microphone provided with a wireless transmission control unit for wirelessly transmitting to a laser pointer through a transmission unit; A wireless receiver for receiving an output signal from the wireless microphone, a first button portion for controlling page up / down of the presentation screen and a scroll wheel, and a second button portion for adjusting the volume of the voice output of the wireless microphone user. The multiplexing unit or the multiplexing unit which integrates and outputs the voice data from the wireless microphone input through the wireless receiver and a control signal generated by the laser pointer into a single signal, or packages and adds the control signal generated by the voice data. A laser pointer provided with a wireless transmission control unit for wirelessly transmitting an output signal through the encapsulation unit, the multiplexing unit, or the encapsulation unit to a USB interface through a wireless transmission unit; Interface to a computer for presentation, the wireless receiver for receiving the output signal from the laser pointer, the memory for storing the presentation data, the output signal of the laser pointer received through the wireless receiver is demultiplexed and outputted separately. Disclosed is a technical configuration including a USB interface having a data processing unit for decoding and outputting voice data after decoding or decapsulating the voice data, respectively.

In addition, the present invention uses a system in which a wireless microphone, a laser pointer, a USB interface interfaced to a computer, and a high power / capacity speaker connected to the computer are linked; Receiving and encoding an analog voice signal of a presentation user from a wireless microphone and wirelessly transmitting the same to a laser pointer; Performing a multiplexing or encapsulation process of a control signal and a received voice signal generated by the laser pointer and wirelessly transmitting the result to a USB interface; Performing demultiplexing or decapsulation in a computer equipped for a USB interface or a presentation to separate or classify the signal and output the audio signal; The separated or classified voice signal is disclosed by amplifying and outputting a high power / capacity speaker connected to a computer and executing a corresponding control command in accordance with a control signal in a computer.

However, the above-described invention discloses convenience of using a microphone by wirelessly transmitting a voice and a control signal to a presentation device.

However, one cannot overlook the importance of presentation timeliness in the importance of presentation. If you give a large amount of data at a given time, you will not be able to check the remaining presentation time and the page of the current presentation. In addition, there is a case where it is necessary to store the presentation contents of the presenter, in this case there is a problem that can be recorded the announcement contents if a separate recording facility is installed.

Accordingly, the present invention can confirm the present presentation material page and the remaining presentation time in the wireless transmitter and method for presenting device in the present invention, and store the presenter's presentation in connection with the ongoing presentation page. This is desired.
