본 발명의 실시예들은 3D 영상 제공 서비스 시스템 및 방법에 관한 것으로, 3D영상을 무선의 전용안경을 통해 제공/시청하는 환경을 제공하는데 있어서, 기존의 가격/크기 문제 및 무선신호 수신범위의 한계, 그리고 이로 인한 3D영상 제공 환경의 대형화 및 효율성의 제한을 개선할 수 있는 3D 영상 제공 서비스 시스템 및 방법에 관한 것이다.Embodiments of the present invention relate to a 3D image providing service system and method, and in providing an environment for providing / viewing 3D image through a dedicated glasses for wireless, there are limitations of existing price / size problems, wireless signal reception range, The present invention also relates to a 3D image providing service system and a method for improving the size of the 3D image providing environment and the limitation of efficiency.
최근에는 평면적인 영상이 아닌 입체감 있는 3D(Three Dimensions) 영상에 대한 관심이 높아지면서 3D영상으로 제작된 영화, 비디오컨텐츠 등이 등장하고 있다. 이러한 3D영상을 보다 깨끗하고 현실감 있게 제공/시청하기 위해서는 기본적으로 사용자가 3D 전용의 특수 안경을 착용하는 것이 일반적이다.Recently, as interest in 3D (Three Dimensions) images, which are not planar images, is increasing, movies and video contents produced with 3D images are emerging. In order to provide / view these 3D images more clearly and realistically, it is common for a user to wear special glasses exclusively for 3D.
여기서, 3D 전용의 특수 안경은 두 가지가 있는데 편광안경 방식과 액정셔터 방식(Active Glass 방식)이다. 이 중, 액정셔터 방식(Active Glass 방식)은 액정으로 되어 있는 특수 안경에서 매우 짧은 시간에 좌/우 액정 즉 좌안/우안 각각을 번갈아 가면서 On/Off하면서 빛의 정보를 통과시켜준다.Here, there are two special glasses for 3D only, polarized glasses and liquid crystal shutter (Active Glass). Among these, the liquid crystal shutter method (Active Glass method) passes light information while switching on / off the left / right liquid crystals, that is, the left eye / right eye, in a very short time in special glasses made of liquid crystal.
헌데, 본 발명에서 고려하는 액정셔터 방식(Active Glass 방식)에서 기존에 사용하는 적외선 방식의 경우, 영사기 측의 적외선 송신장치 및 특수 안경 측의 적외선 수신장치의 가격, 크기, 무게, 배터리 사용량 등 하드웨어적인 면에서 단점이 매우 크다.However, in the case of the infrared method conventionally used in the liquid crystal shutter method (active glass method) considered in the present invention, the hardware, such as the price, size, weight, battery usage of the infrared transmitter of the projector side and the infrared receiver of the special glasses side On the downside, the downside is very big.
또한, 기존의 액정셔터 방식(Active Glass 방식)은, 적외선 방식을 이용하기 때문에, 적외선을 발생하는 적외선 송신장치의 수신 범위가 매우 한정적이고, 이로 인해 3D영상을 동시에 제공/시청할 수 있는 관객의 수가 제한적일 수 밖에 없다. 그리고, 기존의 액정셔터 방식(Active Glass 방식)은, 적외선 방식을 이용하기 때문에, 사람 또는 기둥 등 장애물로 인하여 적외선을 제대로 수신하지 못하는 구간이 발생함에 따른 제공/시청 환경의 문제를 야기시킬 수 있다.In addition, since the conventional liquid crystal shutter method (Active Glass method) uses an infrared method, the reception range of the infrared transmitter that generates infrared rays is very limited, and thus the number of audiences who can simultaneously provide / view 3D images It must be limited. In addition, since the conventional liquid crystal shutter method (Active Glass method) uses an infrared method, a problem of providing / viewing environment may occur due to a section in which infrared rays are not properly received due to an obstacle such as a person or a pillar. .

이에, 절전모드제어부(530)는, 발생한 자체 동기신호를 양안구동부(520)로 제공함으로써, 양안구동부(520)로 하여금 상기 자체 동기신호를 토대로 3D영상을 주시하는 양안 각각의 온/오프 동작을 제어하도록 한다.Accordingly, the power saving mode control unit 530 provides the binocular driving unit 520 with the generated self synchronizing signal, thereby allowing the binocular driving unit 520 to turn on / off each of the binoculars to watch the 3D image based on the self synchronizing signal. Take control.
이때, 절전모드제어부(530)는, 동기제어장치(200)로부터 제공된 동기신호를 토대로 동기화를 수행한 후, 이전에 설정된 절전모드시간 동안 발생한 자체 동기신호 및 무선신호부(510)에서 처리된 금번 동기신호 간의 오차시간 범위에 대응하여 절전모드시간을 조정하고, 조정된 절전모드시간 동안 무선신호부(510)의 수신 동작을 중단시키고 금번 동기신호에 기초한 자체 동기신호를 발생할 수 있다.At this time, the power saving mode control unit 530 performs synchronization based on the synchronization signal provided from the synchronization control device 200, and then processes the self synchronization signal generated during the previously set power saving mode time and the wireless signal unit 510. The power saving mode time may be adjusted according to the error time range between the synchronization signals, the reception operation of the wireless signal unit 510 may be stopped during the adjusted power saving mode time, and a self synchronization signal based on the synchronization signal may be generated.
즉, 절전모드제어부(530)는, 동기화 수행 후 절전모드로 진입할 때마다, 직전 절전모드시간 동안 발생한 자체 동기신호 및 무선신호부(510)에서 처리된 금번 동기신호 간의 오차시간 범위를 측정하여 오차시간 범위에 따라 절전모드시간을 조정함으로써, 조정된 절전모드시간을 이용하여 절전모드(무선신호부(510)의 수신 동작을 중단, 자체 동기신호를 발생)에 진입할 수 있다.That is, each time the power saving mode controller 530 enters the power saving mode after performing synchronization, the power saving mode control unit 530 measures an error time range between the self synchronization signal generated during the previous power saving mode time and the current synchronization signal processed by the wireless signal unit 510. By adjusting the power saving mode time according to the error time range, the adjusted power saving mode time can be used to enter the power saving mode (stopping the reception operation of the wireless signal unit 510 and generating its own synchronization signal).
예를 들어, 절전모드제어부(530)는, 동기제어장치(200)로부터 제공된 동기신호를 토대로 동기화를 수행한 후, 직전 절전모드시간 동안 발생한 자체 동기신호 및 금번 수신한 동기신호 간의 오차시간을 측정하여, 오차시간 범위가 기 정의된 기준값 미만인 경우 절전모드시간의 시간간격을 소정 단계 늘리도록 조정함으로써 자체 동기신호를 이용하는 시간이 길어지도록 한다. 한편, 절전모드제어부(530)는, 동기화를 수행한 후, 직전 절전모드시간 동안 발생한 자체 동기신호 및 금번 수신한 동기신호 간의 오차시간을 측정하여, 오차시간 범위가 기 정의된 기준값 초과인 경우 절전모드시간의 시간간격을 소정 단계 줄이도록 조정함으로써 자체 동기신호를 이용하는 시간이 짧아지도록 하고, 오차시간 범위가 기 정의된 기준값인 경우 절전모드시간의 시간간격을 유지함으로써 자체 동기신호를 이용하는 시간이 유지되도록 할 수 있다.For example, the power saving mode control unit 530 performs the synchronization based on the synchronization signal provided from the synchronization control device 200, and then measures an error time between the self synchronization signal generated during the previous power saving mode time and the synchronization signal received this time. When the error time range is less than the predetermined reference value, the time for using the self-synchronization signal is lengthened by adjusting the time interval of the power saving mode time to be increased by a predetermined step. Meanwhile, after performing synchronization, the power saving mode control unit 530 measures an error time between the self synchronization signal generated during the previous power saving mode time and the synchronization signal received this time, and when the error time range exceeds the predetermined reference value, By adjusting the time interval of the mode time to be reduced by a predetermined step, the time using the self synchronization signal is shortened. If the error time range is a predefined reference value, the time using the self synchronization signal is maintained by maintaining the time interval of the power saving mode time. You can do that.
그리고, 절전모드제어부(530)는, 절전모드시간이 경과하면 무선신호부(510)의 중단시킨 수신 동작을 재개시킨다. 이에, 절전모드제어부(530)는, 무선신호부(510)를 통해 수신된 무선신호에 따른 동기신호를 토대로 동기화를 수행하여 양안구동부(520)가 3D영상을 주시하는 양안 각각의 온/오프 동작할 수 있도록 제어할 것이다.Then, the power saving mode control unit 530 resumes the reception operation in which the radio signal unit 510 is interrupted when the power saving mode time elapses. Accordingly, the power saving mode control unit 530 performs synchronization based on the synchronization signal according to the wireless signal received through the wireless signal unit 510, so that the binocular driving unit 520 turns on / off each eye of the 3D image. I will control it.
이에, 본 발명에 따른 전용안경장치(300)는, Zigbee 등의 WPAN 기술을 적용한 동기신호를 수신하여 3D영상을 관람/시청하는데 있어서, 동기제어장치(200)로부터의 동기신호를 주기적(예 : 절전모드시간 경과 시)으로 수신하여 동기화 하고, 절전모드시간 동안은 무선신호 수신 기능 중단 및 자체 동기신호를 발생하여 이를 통해 동기화함으로써, 3D영상 관람/시청에 문제를 발생시키지 않으면서 전용안경장치(300) 내 배터리(미도시)의 전력손실을 효과적으로 절감할 수 있다.Accordingly, the dedicated eyeglass apparatus 300 according to the present invention periodically receives a synchronization signal applied with a WPAN technology such as Zigbee and the like to view / view a 3D image, and periodically (eg, receives a synchronization signal from the synchronization control device 200). Receives and synchronizes with the power saving mode time elapsed, and during the power saving mode time, the wireless signal reception function stops and generates a self-synchronizing signal and synchronizes it through it, without causing a problem in viewing / viewing the 3D video. 300 may effectively reduce the power loss of the battery (not shown).
그리고, 무선신호부(510)는, 수신된 무선신호로부터 3D영상에 대한 동기신호를 분석/처리하는 과정에서 노이즈로 인한 왜곡 발생이 인지되면, 상기 무선신호에 대응하는 무선채널 변경을 동기제어장치(200)에 요청할 수 있다.When the wireless signal unit 510 detects distortion caused by noise in the process of analyzing / processing the synchronization signal for the 3D image from the received radio signal, the wireless signal unit 510 changes the radio channel corresponding to the radio signal. Request 200.
예를 들어, 2.4GHz를 사용하는 Zigbee 방식의 경우, WiFi 등의 신호에 의하여 영향을 받을 수 있다. 일반적인 상황에서는 문제가 없지만 WiFi송신장치가 근접거리에서 대량의 Data를 송수신할 경우 Zigbee의 신호에 영향을 미칠 수 있다. 이때 Zigbee의 수신측 즉 전용안경장치(300)에서는, 동기제어장치(200)의 무선신호를 해석하는 과정에서 왜곡이 발생된 사실을 인지할 수 있다. For example, the Zigbee method using 2.4 GHz may be affected by a signal such as WiFi. There is no problem in general situation, but if WiFi transmitter sends and receives a large amount of data in close range, it can affect Zigbee's signal. At this time, the reception side of the Zigbee, that is, the dedicated glasses device 300, it can recognize that the distortion occurred in the process of analyzing the radio signal of the synchronization control device 200.
기본적으로는 WiFi 대역의 Guard Band를 이용하여 Zigbee의 무선채널을 선택하여 사용하도록 고안하게 되지만 이렇게 주변 잡음이 심하여 왜곡의 가능성이 있을 때에는 수신측 즉 전용안경장치(300)에서 송신측 즉 동기제어장치(200)에 무선채널의 변경을 요청하는 것이 바람직할 것이다.Basically, it is designed to select and use Zigbee's wireless channel by using Guard Band of WiFi band. However, when the surrounding noise is severe and there is a possibility of distortion, the receiver, that is, the synchronous control device, in the dedicated glasses device 300. It would be desirable to request 200 to change the wireless channel.
즉, 무선신호부(510)는, 수신된 무선신호로부터 3D영상에 대한 동기신호를 분석/처리하는 과정에서 노이즈로 인한 왜곡 발생임을 나타내는 기 설정된 왜곡 발생이 인지되면, 무선신호에 대응하는 무선채널 변경을 동기제어장치(200)에 요청한다.That is, the wireless signal unit 510 recognizes a distortion caused by noise in the process of analyzing / processing a synchronization signal for the 3D image from the received wireless signal, and when the preset distortion is detected, the wireless channel corresponding to the wireless signal. Request the change to the synchronization control device 200.
이에, 전술한 바와 같이 동기제어장치(200)는 무선채널 변경 요청에 대응하여 최적의 무선채널을 할당하여, 할당한 무선채널을 통해 동기제어장치(200) 및 전용안경장치(300) 간에 무선신호를 송/수신할 것이다.Accordingly, as described above, the synchronization control apparatus 200 allocates an optimal radio channel in response to the radio channel change request, and transmits a radio signal between the synchronization control apparatus 200 and the dedicated glasses 300 through the allocated radio channel. Will send / receive.
한편, 동일한 방식을 이용하는 동기제어장치가 다수 존재하고 전용안경장치도 다수 존재할 경우, 전용안경장치가 어떤 특정한 동기제어장치를 선택하여 이로부터의 무선신호를 수신해야 하는 경우가 발생할 수 있다. 이럴 경우, 동기제어장치 및 전용안경장치 간에는 미리 인증을 하여 해당 동기제어장치의 무선신호 만을 수신하겠다고 셋팅할 필요가 있을 것이다.On the other hand, when there are a large number of synchronous control devices using the same method and a plurality of dedicated eyeglasses, there may be a case where the dedicated eyeglasses need to select a specific synchronous control device and receive a radio signal therefrom. In this case, it may be necessary to set the reception of only the radio signal of the synchronous control device by authenticating between the synchronous control device and the dedicated eyeglass device in advance.
이에, 무선신호부(510)는, 사용자의 조작에 따라 인증수행이 선택되면, 동기제어장치(200)로부터 수신되는 무선신호 내의 인증정보를 추출하여 기록하며, 금번 인증수행이 종료된 이후 외부로부터 수신되는 무선신호 중 상기 기록한 인증정보에 대응되는 무선신호를 선택/처리할 수 있다.Therefore, when the authentication operation is selected according to the user's operation, the wireless signal unit 510 extracts and records authentication information in the wireless signal received from the synchronization control apparatus 200, and after the authentication is completed this time, The wireless signal corresponding to the recorded authentication information may be selected / processed from the received wireless signals.
즉, 무선신호부(510)는, 전용안경장치(300)의 사용자가 인증수행을 위한 특정버튼을 선택하는 등과 같이 사용자의 조작에 의해 인증수행이 선택되면, 동기제어장치(200)로부터 수신되는 무선신호 내의 인증정보(예 : 인증번호)를 추출하여 기록한다. 그리고, 무선신호부(510)는, 자신의 인증정보(예 : 인증번호)를 포함시킨 인증을 위한 무선신호를 전용안경장치(300)로 회신/제공할 수 있다.That is, the wireless signal unit 510 is received from the synchronous control device 200 when the authentication operation is selected by the user's operation, such as the user of the dedicated eyeglasses device 300 selecting a specific button for performing the authentication. Extract and record authentication information (eg authentication number) in the radio signal. In addition, the wireless signal unit 510 may return / provide a wireless signal for authentication including its own authentication information (eg, an authentication number) to the dedicated glasses device 300.
이에, 무선신호부(510)는, 금번 인증수행이 종료되면, 외부로부터 수신되는 무선신호들 중 전술에서 기록한 인증정보(예 : 인증번호)에 대응되는 무선신호 만을 선택하여, 이로부터 동기신호를 분석/처리할 수 있다. Therefore, when the authentication process is completed, the wireless signal unit 510 selects only the wireless signal corresponding to the authentication information (eg, the authentication number) recorded in the above from among the wireless signals received from the outside, and selects a synchronization signal therefrom. Analyze / Process
이에, 본 발명에 따른 전용안경장치(300)는, Zigbee 등의 WPAN 기술을 적용한 동기신호를 수신하여 3D영상을 관람/시청하는데 있어서, 여러 동기제어장치 중 해당되는 동기제어장치(200)와의 사전 인증을 통해 적합한 무선신호를 해당 동기제어장치(200)와 송/수신할 수 있도록 한다.Therefore, the dedicated glasses device 300 according to the present invention, in order to view / view a 3D image by receiving a synchronization signal applied with a WPAN technology such as Zigbee, etc., in advance with a corresponding synchronization control device 200 among various synchronization control devices. Through authentication, it is possible to transmit / receive a suitable radio signal with the corresponding synchronous control device 200.
그리고, 무선신호부(510)는, 무선신호를 제공하는 동기제어장치(200)의 전원 오프(OFF)를 인지하거나 또는 기 설정된 수신대기시간이 경과하는 동안 동기제어장치(200)로부터 무선신호가 수신되지 않는 경우, 이를 전원제어부(540)에 통지하여 전원제어부(540)로 하여금 장치 내부의 전원 공급을 턴-오프하도록 할 수도 있다.The wireless signal unit 510 recognizes the power OFF of the synchronous control device 200 that provides the wireless signal, or the wireless signal is transmitted from the synchronous control device 200 while the preset reception standby time elapses. If not received, the power controller 540 may be notified to cause the power controller 540 to turn off the power supply inside the apparatus.
이상에서 설명한 바와 같이, 본 발명에 따른 3D 영상 제공 서비스 시스템은, Zigbee 등의 양방향 통신 규격의 WPAN 기술을 동기제어장치(200) 및 전용안경장치(300)에 적용함으로써 WPAN 기술을 적용한 동기신호를 송/수신하여 3D영상을 관람/시청할 수 있도록 하고, 더 나아가 기 설정된 절전모드시간 동안은 전용안경장치(300)에서 무선신호 수신 기능 중단 및 자체 동기신호를 발생하여 이를 통해 동기화함으로써 3D영상 관람/시청에 문제를 발생시키지 않으면서 전용안경장치(300) 내 배터리(미도시)의 전력손실을 효과적으로 절감할 수 있다.As described above, the 3D image providing service system according to the present invention applies the WPAN technology of the bidirectional communication standard such as Zigbee to the synchronization control device 200 and the dedicated glasses device 300 to apply the synchronization signal applying the WPAN technology. 3D video can be viewed / viewed by sending / receiving, and furthermore, during the preset power saving mode, the dedicated glasses device 300 stops the wireless signal reception function and generates a self-synchronizing signal to synchronize 3D video.

In this case, the image providing device 100 alternately outputs the left and right eye screens based on the synchronization signal provided to the synchronization control device 200 in the process of outputting the 3D image by a time division synchronization (Sync) method. desirable.
동기제어장치(200)는, 영상제공장치(100)로부터 제공되는 3D영상에 대한 동기신호를 수신하고, 동기신호를 포함하는 양방향 통신 규격의 무선신호를 생성하여(S30) 외부로 송출한다(S40). 이에, 동기제어장치(200)에서 지원하는 양방향 통신 규격의 무선신호에 따른 수신 범위 내의 수신대상(예 : 적어도 하나의 전용안경장치(300a,300b...))은, 동기제어장치(200)로부터의 무선신호를 수신할 것이다.The synchronization control apparatus 200 receives a synchronization signal for a 3D image provided from the image providing apparatus 100, generates a wireless signal of a bidirectional communication standard including the synchronization signal (S30), and transmits it to the outside (S40). ).

It may be a display device or a video content server providing content of a 3D image to a corresponding device (for example, the synchronous control device 200). Hereinafter, for convenience of description, the image providing apparatus 100 will be described with reference to an embodiment in which a 3D image is projected onto the screen 1.
이러한 영상제공장치(100)는, 3D영상을 출력함(S11)에 있어서 해당 3D영상에 대응하여 보유한 데이터를 토대로 해당 3D영상에 대한 동기신호를 동기제어장치(200)로 제공한다(S12). 이때, 영상제공장치(100)는, 시분할 동기(Sync)방식에 의해, 3D영상을 출력하는 과정에서 좌안과 우안의 화면을 동기제어장치(200)로 제공하는 상기 동기신호를 토대로 번갈아 출력하는 것이 바람직하다.The image providing apparatus 100, in outputting the 3D image (S11), provides a synchronization signal for the 3D image to the synchronous control apparatus 200 based on the data held corresponding to the 3D image (S12). In this case, the image providing device 100 alternately outputs the left and right eye screens based on the synchronization signal provided to the synchronization control device 200 in the process of outputting the 3D image by a time division synchronization (Sync) method. desirable.
동기제어장치(200)는, 영상제공장치(100)로부터 제공되는 3D영상에 대한 동기신호를 수신하고, 동기신호를 포함하는 양방향 통신 규격의 무선신호를 생성하여(S13) 외부로 송출한다(S14). 이에, 동기제어장치(200)에서 지원하는 양방향 통신 규격의 무선신호에 따른 수신 범위 내의 수신대상장치 즉 적어도 하나의 전용안경장치(300)는, 동기제어장치(200)로부터의 무선신호를 수신할 것이다.The synchronization control apparatus 200 receives a synchronization signal for a 3D image provided from the image providing apparatus 100, generates a radio signal of a bidirectional communication standard including the synchronization signal (S13), and transmits it to the outside (S14). ).

In operation S18, the on / off operation of each of the two eyes looking at the 3D image is controlled based on the self-synchronization signal.
이처럼, 자체 동기신호를 토대로 3D영상을 주시하는 양안 각각의 온/오프 동작을 제어하는 중 전용안경장치(300)는 절전모드시간이 경과하는지 여부를 판단하여(S19), 절전모드시간이 경과하지 않으면 전술의 S17~S19단계를 반복하고, 절전모드시간이 경과하면 중단시킨 무선신호 수신 기능을 재개한다(S19-1).As described above, the exclusive glasses device 300 determines whether the power saving mode time has elapsed while controlling the on / off operation of each of the binoculars watching the 3D image based on its own synchronization signal (S19). If not, the above steps S17 to S19 are repeated, and when the power saving mode time has elapsed, the radio signal receiving function stopped is resumed (S19-1).
