The present invention relates to a transmitter and a method for time adjustment and alarm in a presentation transmission and reception system, and more particularly, a transmitter capable of performing a stop watch function and a timer function to check and notify a presenter's announcement time. And to a method.

Recently, it is often seen in academic conferences, seminars, lectures, lectures, etc. It is a form of presentation using a presentation program, that is, a microcomputer's application, PowerPoint, which is then displayed on a projector and explained using a laser pointer. Currently, the presenter mainly explains and performs page up / down through key operations on the computer.

Of course, although the projector has an infrared remote control, very few people use it. The use of a remote control with a laser pointer is cumbersome and the infrared method is directional.

In order to solve this problem, a technique has been proposed in which a page up / down function is mounted on a laser pointer and a page pointer can be freely manipulated by a radio frequency (RF) while using the laser pointer.

1A and 1B are diagrams illustrating a presentation transmission / reception system having a structure of a conventional transceiver, and the conventional presentation transmission / reception system is largely based on a laser pointer 10 of a transmitter 100 and a wireless receiver of a receiver 200 ( 20).

The serial data is modulated by the radio transmitter 34 and transmitted wirelessly through the antenna 35. At this time, the encoder 33 inserts a predetermined number of bits (20 bits) representing the unique ID of the laser pointer 10 in the process of encoding the enable signals input from the page up / down buttons 31 and 32.

The radio receiver 40 of the receiver receives and decodes the radio signal generated from the laser pointer 10 in the radio receiver 42 through the antenna 41 and transmits 4 bytes of data to the microcontroller 43 of the controller 46. Will be sent. The microcontroller 43 recognizes the page control command and generates the same signal as the trigger signal generated by the photo coupler and sends it to the mouse controller 44. The mouse controller 44 receiving the simulated signal is regarded as a signal generated by the manipulation of the scroll switch in the 3D mouse and transmits the page up / down signal to the computer through the USB or PS / 2 port 45. .

The user can use the laser pointer 10 as one set for any wireless receiver 40. In addition, since the conventional presentation transmission / reception system is a wireless communication method, a single laser pointer 10 may be used in an environment in which the presenter is presented to the audience through a plurality of laptop computers such as a notebook computer owned by the audience other than the projector connection computer used by the presenter. The same data can be transmitted and presented to a plurality of computers that exist within a predetermined radius capable of wireless communication and to which the receiver 200 is connected.
