## Title
Multifunctional remote control device

## Abstract

The present invention provides a multifunctional remote control device. It characterizes that after a memory card is inserted in a memory card slot, a memory card control circuit instantly reads the audio/visual data in the memory card. Meanwhile a control button on a panel keyboard directs the commands to a control circuit through a panel circuit. The control circuit drives the memory card control circuit to send audio/visual data to a coding circuit which translates the data to wireless signals. The wireless signals are then sent by a transmitter and picked up by the receiving device of the receiver. A power source joint disposed at the rear side of the receiver is for the power supply. The panel keyboard sends audio/visual viewing commands such as forwarding, rewarding and volume through the control circuit.

It characterizes that after inserting a memory card (F) in the memory card slot (C3), the memory card control circuit (C7) instantly reads the audio/visual data in the memory card (F), commands are sent to the control circuit (C7) via the panel circuit (C6) from the buttons of the panel keyboard (C1). Said control circuit (C5) then drives the memory card control circuit (C7) sending the audio/visual data to coding circuit (C4). It translates the data into wireless signals (G) which are sent by the transmitter (C2) to the receiving device (D3) of the receiver (D). The decoding circuit (D4) thereof translates wireless signals (G) into audio/visual data which is input to the coding circuit (D5) and translated to TV signals (D6) receivable by a television set (A). The TV signals (D6) are directed to the television set (A) from the signal joint (D2) at the rear side of the receiver (D) and output from screen and speakers. A power source joint (D1) is also disposed at the rear side of the receiver (D) for the power supply of the receiver (D).
Said panel keyboard (C1) commands viewing functions such as forwarding, rewarding, volume, reversing, of the audio/visual data through the control circuit (C5). Moreover, the memory card control circuit (C7) thereof reads digital media files such as MPEG2, MPEG3, MPEG4, AVI, RM, JPG, BMP.
The wireless signals herein (G) are the agent and signal transportation systems and can be further applied in wireless data transmission such as infrared, radio and Bluetooth.
The memory card slot (C3) herein can be applied further as the storage agent for digital data in portable electronics such as CF card and MD card.
The signal joint (D2) of said receiver (D) can be set as joint applied in the input of TV signals such as S-SVIDO and AV terminal.
Referring FIGS. 6 and 7, the remote control (C) of the present invention is able to equip LCD display function comprising panel keyboard (E1), transmitter (E2), memory card slot (E3), coding circuit (E4), control circuit (E5), panel circuit (E6), memory card control circuit (E7), image processing circuit (E8), LCD display (E9) and power button (E10).
The feature of the said LCD display function is that after the memory card (F) is inserted into the memory card slot (E3), the memory card slot (E3) instantly reads the audio/visual data in the memory card (F), and commands are sent to control circuit (E5) from the control button on the panel keyboard (E1) via the panel circuit (E6). The control circuit (E5) drives the memory card control circuit (E7) sending the audio/visual data to the coding circuit (E4) which translates the data into wireless signals (G) transmitted by the transmitter (E2). Said wireless signals (G) are then picked up by the receiving device (D3) of the receiver (D), translated into audio/visual data by the decoding circuit (D4) and input to the coded circuit (D5).
