The present invention is an artificial intelligence remote control device capable of outputting sound by transmitting data read from the artificial intelligence remote control device through a B-CDMA (Binary CDMA) transmission and reception to a plurality of earphone devices having a B-CDMA module in a certain area It is about.

In general, most remote control devices are manufactured in a compact type, which is easy to carry with only an MP3 player function. The intelligent remote control device has a structure in which a user can listen to stored data such as music through earphones which are output devices by decoding stored data of a memory device installed therein.

The conventional remote control device can listen to music or FM broadcast through the internal earphones, earphones and cables connected to the output device, and when listening through the internal earphones, there is a risk of disturbing others due to sound, and also earphones And when listening to music or broadcasting using an external earphone, there was an inconvenience to be connected to the remote control device with a cable.

Accordingly, the present invention has been made to solve the above conventional problems,

When the device selection, channel selection, channel selection and volume control are transmitted and received as infrared signals, and the audio output switching signal is wirelessly received from the 5.1 channel audio and video, the audio output signal output from the wired or wireless 5.1 channel speaker unit An artificial intelligence remote control unit 30 for converting an audio signal output to an external earphone unit connected to one side through a short range wireless audio transmitter;

It is achieved by being composed of an external earphone unit 40 connected to one side of the artificial intelligence remote control unit for outputting an audio signal wirelessly provided by a B-CDMA (Binary-CDMA) module.

Hereinafter, the artificial intelligence remote control system of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an artificial intelligent remote control device according to the present invention, which is a B-CDMA (Binary-CDMA) module 10, 5.1-channel speaker unit 20, artificial intelligence remote control unit 30, external earphone It is comprised by the part 40.

First, B-CDMA will be described.

The B-CDMA 10 is an external input / output device that maintains a constant envelope of each external A / V signal of a center sound, front left and right sounds, a bass sound, and rear left and right sounds corresponding to 5.1 channels through multiple codes. It is installed inside the speaker, front left and right speakers, sub-woofer and rear left and right speakers. In order to keep the envelope of the external A / V signal constant, noise is generated during the truncation of the transmitter to a finite value, and minimizing the noise has a great effect on improving performance. In addition, chip error is caused by additive white noise while an external A / V signal is being transmitted.

In order to accurately analyze the noises, noise generated by truncation may be obtained by approximating Gaussian since the distribution of the multiple code signals follows the Gaussian distribution when the number of codes is large.

In addition, the noise caused by the PSK modulated chip can be approximated to Gaussian after despreading if the spreading factor is large and the autocorrelation property of the code used is good. The above two approximations can theoretically analyze the B-CDMA performance.

Particularly, B-CDMA includes PW-CDMA for converting the size of the truncated signal to the width of the signal, MP-CDMA for converting the phase of the signal, and CS-CDMA for selecting and transmitting a code using a transmission bit. Any one is selected and configured, and the B-CDMA according to the present invention is configured as an MP-CDMA system for converting to an external A / V signal phase.

In addition, a signal summed using multiple codes has a large PAR (peak to average power ratio) and becomes more serious as the number of codes used increases. At this time, the MP-CDMA according to the present invention cuts the signal to a finite value and then PSK modulates it. The envelope is constant because the PSK modulated signal differs only in phase. The receiver detects the PSK modulated chip, inverts the phase of the signal to the magnitude of the external signal, and detects the transmitted bit in correlation with the code.

The B-CDMA according to the present invention having such characteristics will be compared with the conventional Bluetooth (Bluetooth) and wireless LAN (Wireless LAN) with Table 1.

Bluetooth Wireless LAN Binary CDMA (B-CDMA) Sound Quality Bad Good (no compression) Good (no compression) Power Consumpation Medium (80mA) Lot (more than 100mA) Low (less than 40mA) Confliction none none has exist Size Big small Big Price usually expensive usually Controllability Bad Bad good

As such, the intelligent remote control device using B-CDMA has a good effect of minimizing power consumption by reducing the burden of the power amplifier than Bluetooth and WLAN.

By using the characteristics of B-CDMA, it is installed inside the center speaker, front left and right speakers, sub-woofer and rear left and right speakers that are 5.1-channel speakers, and it keeps the envelope of external A / V signal flowing through multiple codes constant.
