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

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 realize 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 that the cost of the wireless communication terminal increases due to the cost required to implement this.

The present invention has been proposed to solve the above problems, and to implement a surround sound by receiving different sound source data of sound from a multi-channel sound providing system using a wireless communication terminal corresponding to the number of channels of sound, An object of the present invention is to provide a method for implementing surround sound using a wireless communication terminal.

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; A second step of forming a group for each wireless communication terminal to receive sound source data of sound; A third step in which each of the wireless communication terminals forming the group receives the sound source data of the sound for each channel corresponding to each other from the multi-channel sound providing server; And a fourth step of each of the wireless communication terminals receiving the sound source data of the sound from the multi-channel sound providing server for each channel corresponding to each other to implement surround sound in real time.

Another method of the present invention provides a method for 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 are connected; A second step of confirming whether a group is formed according to request of sound source data of sound from the plurality of connected wireless communication terminals; And a third step of transmitting each sound source data of the requested sound to each wireless communication terminal corresponding to each other according to the confirmation that the group is formed.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of a multi-channel sound providing system to which the present invention is applied.

As shown in FIG. 1, in the multi-channel sound providing system to which the present invention is applied, a predetermined group is formed by connecting to the multi-channel sound providing server 14 using a wireless LAN or a wireless communication network and the like. A plurality of wireless communication terminals 11 for implementing surround sound by receiving different sound source data, and a session manager 12 for performing a login procedure as the wireless communication terminal 11 is connected to receive sound source data of sound. ), As the storage unit 13 and the logged-in wireless communication terminals 11, which store sound source data of various types of sound for each channel, form a group, a wireless communication terminal corresponding to the number of channels of sound to be transmitted ( After confirming whether or not 11) participated in the group, multi-channel for transmitting different sound source data of sound to each wireless communication terminal 11 for each channel And a fragrance-providing server (14).

Here, the reason for forming the group will be described by way of example. Six friends connect to the multi-channel sound providing server 14 to receive 5.1-channel surround sound. At this time, other than the above six people can also be connected. Therefore, the multi-channel sound providing server 14 may not know which wireless communication terminal 11 should transmit the multi-channel sound source data constituting one sound. To this end, when the wireless communication terminal 11 is connected, a kind of room (group) is opened in the multi-channel sound providing server 14.

Thereafter, as the wireless communication terminals corresponding to the number of sound sources (number of channels) of the sound join the corresponding group, different sound sources constituting one sound are transmitted for each channel. That is, the wireless communication terminals participating in the group receive different sound source data constituting one sound for each channel.

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 must be registered in advance in the multi-channel sound providing system to receive the multi-channel sound.

Then, each wireless communication terminal 11 forms a group with other wireless communication terminals in order to receive sound source data of sound (302). At this time, the number of wireless communication terminals 11 should be equal to the number of sound sources (number of channels) of the sound to be transmitted.

When the group is formed as described above, the wireless communication terminal 11 requests transmission of sound source data of sound (303). Then, the multi-channel sound providing server 14 checks whether the number of channels (sound sources) of the sound to be transmitted and the number of wireless communication terminals participating in the group are the same, and in the same case, transfers each sound source data of sound to the corresponding wireless communication terminals. Transmit (304). Of course, if it is not the same, all the radio communication terminals 11 participating in the group do not transmit sound source data, and the "number of radio communication terminals participating in the group is insufficient." Send a message.

Thereafter, the plurality of wireless communication terminals 11 output surround sound data of the multi-channel sound received from the multi-channel sound providing server 14 in real time to implement surround sound (305). At this time, each wireless communication terminal may store the received sound source data.

In the present invention, the sound is composed of a plurality of sound source data, such as ringtones, music, songs, etc., is output through the voice / sound output unit (23).

In addition, when transmitting sound source data from the multi-channel sound providing server 14 to the wireless communication terminal 11, when the surround sound is implemented, it may also transmit information on which position each wireless communication terminal 11 should be located. have. Of course, this information is displayed through the display unit 25 so that the user can confirm the information.
