Description

Method for implementing surround sound using a plurality of wireless communication terminals {Method for play surround music using a lot of wireless telecommunication terminal}

The present invention relates to a method of implementing surround sound using a plurality of wireless communication terminals, and more particularly, to the sound source data for each channel of sound from a multi-channel sound providing system using a wireless communication terminal corresponding to the number of channels of sound, and the like. The present invention relates to a method of implementing surround sound using a plurality of wireless communication terminals for implementing the best surround sound by receiving setting information according to a specification of a wireless communication terminal.

In the present invention, the wireless communication terminal is a mobile communication terminal, a personal communication service (PCS) terminal, a personal digital assistant (PDA), a smart phone, a next generation mobile communication (IMT-2000) terminal, a wireless LAN terminal and the like through wireless communication Refers to a portable wireless communication terminal capable of transmitting and receiving text and image data.

Earlier wireless terminals did not have multiple speakers and did not support enough power to support multi-channel sound, so sound was output in mono. Then, with the development of wireless communication technology, it is possible to mount two speakers in a wireless communication terminal, thereby outputting stereo sound. However, users are dissatisfied with stereo sound and want to hear more grand sound.

Accordingly, a surround method has emerged as a developed sound reproduction method. The surround method is divided into 5.1 channel, 6.1 channel, 8.1 channel, etc. according to the number of sound sources constituting the sound. Therefore, in order to reproduce the multi-channel sound, a speaker according to the number of channels of the sound must be provided. The reason is that one speaker outputs one sound source (channel).

Here, the mono method, the stereo method and the stereo method and the surround method will be described. First, the mono method is a method of outputting one sound source through a plurality of speakers or one speaker, regardless of how many speakers are connected. In the stereo system, two speakers output different sound sources to implement stereoscopic sound effects.

In addition, the surround method is a method of reproducing a sound composed of two or more sound sources, and requires a plurality of speakers for outputting a sound composed of a plurality of sound sources. For example, the 5.1-channel surround method currently used most often outputs five different sound sources through six speakers and a sound source for emphasizing the bass portions of the five different sound sources. At this time, the six speakers are generally arranged in front of the listener, left front, left back, right front, right back, front, and rear. Here, the speaker disposed on the rear generally means a speaker for a woofer.

Therefore, in order to output surround sound using one wireless communication terminal, a plurality of speakers must be mounted, and the positions of the speakers must be spaced apart from each other. This is a problem in that the structure or technology of the wireless communication terminal is difficult to implement.

In addition, even if a plurality of speakers can be implemented in the wireless communication terminal, there is a problem in that the cost of the wireless communication terminal increases due to the cost required to implement the same.

The present invention has been proposed in order to solve the above problems, by using a wireless communication terminal corresponding to the number of channels of sound from the multi-channel sound providing system, etc., sound source data for each channel and setting information according to the specifications of the wireless communication terminal It is an object of the present invention to provide a method for implementing surround sound using a plurality of wireless communication terminals to receive the best surround sound.

According to an aspect of the present invention, there is provided a method of implementing surround sound using a plurality of wireless communication terminals, the method comprising: a first step of connecting each wireless communication terminal to a multi-channel sound providing server to form a group; A second step of transmitting, by the wireless communication terminal, its own information and information about the number of channels and surrounding environment of the sound to be implemented to the multi-channel sound providing server; A third step of receiving, by the wireless communication terminal, setting information from the multi-channel sound providing server; And a fourth step in which each wireless communication terminal receives sound source data for each channel of sound from the multi-channel sound providing server for each channel corresponding to each other and implements surround sound according to the setting information.

Meanwhile, another method of the present invention provides a method of implementing surround sound in a multi-channel sound providing system, comprising: a first step of performing a login procedure as a plurality of wireless communication terminals access; A second step of receiving the unique information of each wireless communication terminal, the number of channels of the sound to be implemented and the surrounding environment information from the plurality of connected wireless communication terminals; A third step of transmitting the unique information of the received wireless communication terminal, setting information according to channel number and surrounding environment information of the sound to be implemented to the plurality of wireless communication terminals, respectively; And transmitting a sound source data of sound for each channel of the corresponding sound to a corresponding wireless communication terminal according to the sound source data transmission request signal from the wireless communication terminal to implement the best surround sound according to the setting information.

First, when a plurality of wireless communication terminals 11 are connected to receive sound source data of a multichannel sound, the session manager 12 of the multichannel sound providing system performs a login procedure (301). At this time, each wireless communication terminal 11 should be registered in advance in the multi-channel sound providing system.

Thereafter, each wireless communication terminal 11 forms a group with other wireless communication terminals so as to receive sound source data and setting information for each channel of sound, respectively (302). At this time, the number of wireless communication terminals 11 should be equal to the number of sound source data (number of channels) of the sound to be transmitted.

Thereafter, the plurality of wireless communication terminals 11 participating in the group transmit their information (manufacturing serial number, telephone number, etc.), channel number of the sound to be implemented and environment information to the multi-channel sound providing server 14. (303). Then, the multi-channel sound providing server 14 transmits the setting information according to the specification of the received wireless communication terminal, the number of channels to be implemented and the environment information to each wireless communication terminal (304).
