[ And an antenna unit 250 for transmitting the signal to the outside.

The synchronization signal unit 210 analyzes a synchronization signal for a 3D image from the image providing apparatus 100 providing a predetermined 3D (Three Dimension) image, and processes the synchronization signal in a form recognizable by the wireless signal unit 220 .

That is, when the image providing apparatus 100 is a projector for a movie theater, a computer displaying a 3D image, or a general PC or a TV apparatus, the synchronizing signal unit 210 outputs a 3D image And can analyze the received synchronization signal and process it in the form of a signal recognizable by the wireless signal unit 220. [

Alternatively, when the image providing apparatus 100 is an image content server, the synchronizing signal unit 210 synchronizes the 3D image obtained from the 3D image obtained from the image providing apparatus 100 with the 3D image And processes it in the form of a recognizable signal in the wireless signal unit 220.

As described above, when the synchronous control device 200 includes the image reproducer 270, the synchronous control device 200 may be a mobile terminal (e.g., a mobile phone device, a PDA device, or the like).

The wireless signal unit 220 generates a wireless signal of a bidirectional communication standard including the synchronization signal processed by the synchronization signal unit 210.

In this case, the wireless signal unit 220 preferably includes a wireless personal area network (WPAN) module for generating / supporting a short distance wireless signal of a bidirectional communication standard. For example, the wireless signal unit 220 may adopt at least one of various types of WPAN modules such as a Zigbee module, a Bluetooth module, and an UWB (Ultra Wide Band) module.

That is, when a synchronization signal is input from the synchronization signal unit 210, the wireless signal unit 220 generates a short range wireless signal including the synchronization signal (e.g., a Zigbee wireless signal) including the synchronization signal according to a WPAN module (e.g., Zigbee module) Can be generated.

Accordingly, the synchronization control apparatus 200 according to the present invention can apply a WPAN technique such as Zigbee to provide a synchronization signal for a 3D image to a reception target (e.g., at least one dedicated eyeglass unit 300).

At this time, the radio signal unit 220 recognizes a usable radio channel not being used by another device among a plurality of radio channels, allocates an optimal radio channel among the recognized radio channels, The antenna unit 250 can transmit the generated radio signal.

That is, the radio signal unit 220 is a radio communication unit that is not used by another device (for example, another synchronous control device other than the synchronous control device 200) among a plurality of radio channels (for example, 16 radio channels) (E.g., channels 1, 2, and 5) and allocates the best one of the recognized wireless channels (e.g., channels 1, 2, and 5) , And transmit the generated radio signal through the allocated radio channel (e.g., channel 2) by the antenna unit 250.

The method for allocating an optimal radio channel is a method for allocating a radio channel to a radio channel unit 220 from a neighboring other device (e.g., a different-type synchronous control device) (E.g., channels 1, 2, and 5) that are available to the wireless signal unit 220 based on the analysis result, Find a silent channel with the least amount of channel interference that can be caused by a wireless channel that is far from the channel, a wireless channel that is assigned by another device (such as an other control device) 2 may be allocated as an optimal radio channel.

This is achieved by applying a WPAN technique such as Zigbee in the synchronous control device 200, that is, the wireless signal unit 220, to generate a wireless signal including a synchronization signal for the 3D image, ), A higher transmission power level is required for a longer distance depending on the distance to the reception target, and a lower transmission power level is sufficient for a shorter distance.

Alternatively, the distance measuring unit 260 may measure the distance to at least one receiving object from which the synchronous control apparatus 200 according to the present invention receives the radio signal. Of course, in this case, a distance measurement related module corresponding to the distance measuring unit 260 of the synchronous control device 200 may also be provided as the measurement target (corresponding to the dedicated spectacle device 300 of the present invention). Since the distance measuring unit 260 can adopt any of various conventional measurement techniques capable of measuring the distance to an adjacent measurement target (corresponding to the dedicated eyeglass apparatus 300 of the present invention) The description will be omitted.

The wireless signal unit 220 receives the distance information (e.g., 50 m) based on the distance information (e.g., 50 m) between the wireless signal unit 220 and the corresponding receiving object (e.g., at least one dedicated eyeglass unit 300) measured through the distance measuring unit 260 It is also possible to adjust the transmission power level of the radio signal and transmit it through the antenna unit 250.

That is, the management information control unit 230 manages / manages the state management information for each reception object (e.g., the dedicated eyeglass device 300) to manage the reception object list.

More specifically, when a short range wireless signal (for example, a Zigbee wireless signal) is received from at least one reception target (e.g., the dedicated eyeglass unit 300) through the antenna 250, the wireless signal unit 220 receives (For example, Zigbee wireless signal) according to a WPAN module (for example, a Zigbee module) adopted by the wireless communication device 200 and processes it in a form recognizable by the management information control unit 230.

For example, the management information control unit 230 may receive the radio signal previously transmitted from the synchronous control device 200 from the exclusive eyeglass device 300 to the reception subject (e.g., the exclusive eyeglass device 300) (For example, a Zigbee radio signal channel replacement command, a power control command) previously transmitted by the synchronous control device 200 to the special glasses device 300 The battery state management information indicating the remaining amount of the battery of the exclusive eyeglass unit 300 and the emergency state state indicating whether or not a predetermined emergency situation has occurred in the exclusive eyeglass unit 300 Management information, and loss / theft state management information indicating whether the exclusive eyeglass unit 300 has been lost / stolen. Here, the management information control unit 230 may generate the restoration / tearing state management information based on the lost / stolen state information in the state information returned from the exclusive eyeglass unit 300. However, The lost eye / shoplifting state management information may be generated for the corresponding exclusive eyeglass device 300 when the dedicated eyeglass device 300 existing through communication does not respond without a normal end procedure.
