Description

TECHNICAL FIELD [0001] The present invention relates to a method for viewing a digital broadcast program of a multi-angle stereoscopic image based on speech recognition,

The present invention relates to a digital broadcasting program viewing method, and more particularly, to a digital broadcasting program viewing method for providing a digital broadcasting program of a multi-angle stereoscopic image as a stereoscopic video according to a demand of a viewer based on speech recognition.

Thanks to the development of stereoscopic video technology and high-definition display devices, 3D stereoscopic video industry is attracting much attention, such as watching stereoscopic movies in a movie theater or watching broadcast programs produced in stereoscopic video.

There are two ways to view stereoscopic images: wearing glasses and wearing glasses.

The way to wear glasses is to recognize the sense of distance because of the difference between the images seen in the left and right eyes. It is divided into anaglyph filter, polarized filter and time split according to the method of displaying different images in the left and right eyes. Particularly, in the time division system, the display terminal apparatus alternately outputs the left eye image and the right eye image periodically and synchronizes with this period to drive the shutter glasses of the stereoscopic glasses.

It is a one-sided image that transmits images edited at various angles in various sports broadcasts or home shopping broadcasts, but arbitrarily edited by a broadcaster regardless of the viewer's selection. Therefore, viewers can not view images of a specific object or a person at a desired angle and distance.

In consideration of this point, Korean Laid-Open Patent Publication No. 2010-0061278 encodes the captured images in the form of a three-dimensional stereoscopic image including left and right stereoscopic images photographed by a plurality of stereoscopic cameras into a transport stream format for providing a multi-angle digital broadcasting service , And transmits the encoded transport stream to the terminal apparatus. In the multi-angle digital broadcasting service, when a viewer inputs an operation command to receive a plurality of stereoscopic images, a multi-angle image is displayed on the screen in the form of a thumbnail, and one of the thumbnails is selected by the viewer.

Korean Patent Laid-Open Publication No. 2005-0073012 extracts an image-taking angle or distance for each channel from channel information of a multi-angle broadcast, matches each channel to a remote-controller input key arranged corresponding to the image-taking angle or distance, And the channel is switched according to the operation of the input key.

The existing techniques described above focus on providing a viewing environment in which a multi-angle broadcast can be watched, but it is troublesome because a viewer directly manipulates the stereoscopic image of a desired angle. Especially, it is difficult for the viewer to wear the stereoscopic glasses during stereoscopic viewing, and it is difficult to easily operate the remote control. In addition, if the user does not have the remote control, it is difficult to enjoy the stereoscopic image faithfully because the user needs to remove the glasses and search for the remote controller.

It is an object of the present invention to provide a digital broadcasting program viewing system of a multi-angle stereoscopic image based on speech recognition, in which an angle image desired to be viewed by a viewer's voice can be set while viewing a multi-angle stereoscopic image.

Another object of the present invention is to provide a system for viewing a multi-angle stereoscopic image of a multi-angle stereoscopic image based on speech recognition, capable of controlling a terminal device that provides a digital broadcast program of a multi-angle stereoscopic image by a viewer's voice without operating a remote controller There is.

The method for viewing a digital broadcasting program of a multi-angle stereoscopic image based on speech recognition according to the present embodiment includes wearing stereoscopic glasses to view a digital broadcasting program of a multi-angle stereoscopic image; A stereoscopic spectacles unit provided on the stereoscopic glasses requests an angle setting to a display terminal device that provides the digital broadcast program; The display terminal device having received the angle setting request provides angle setting guide information for setting an angle to a viewer wearing the stereoscopic glasses; And wirelessly transmitting angle setting data to the display terminal device according to a result of recognizing the angle ID input by voice by a viewer who has received the angle setting guide information; The display terminal device outputs the image and audio of the stereoscopic image set at an angle.

Providing the angle setting guide information includes suspending audio output by the display terminal device to prevent noise input other than the viewer's voice.

The method for viewing a digital broadcasting program of a multi-angle stereoscopic image based on speech recognition according to the present embodiment includes wearing stereoscopic glasses to view a digital broadcasting program of a multi-angle stereoscopic image; A stereoscopic spectacles unit provided on the stereoscopic glasses requests relay setting of the angle; The remote controller receiving the relay request of the angle setting transmits the remote control to the display terminal device providing the digital broadcasting program; The display terminal device provides angle setting guide information for setting an angle to a viewer wearing the stereoscopic glasses; Requesting the viewer who has been provided with the angle setting guide information to relay the angle ID input by voice; The remote controller transmits an angle ID for setting an angle to the display terminal device; The display terminal device outputs the image and audio of the stereoscopic image set at an angle.

The stereoscopic spectacles unit uses the Bluetooth standard for the relay request to the remote controller and the infrared signal is used for transferring the remote controller to the display terminal unit.

Providing the angle setting guide information includes suspending audio output by the display terminal device to prevent noise input other than the viewer's voice.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, the stereoscopic image viewing system based on speech recognition according to the present invention may include a stereoscopic spectacles unit 100, a remote controller 200, and a display terminal apparatus 300. As shown in FIG.

The display terminal device 300 is a display device for providing a digital broadcasting service and can set general functions such as channel change, screen color adjustment and volume control through remote control using the input unit 301 or the remote controller 200. Typical examples of the display terminal apparatus 300 include a digital television (DTV) and an IPTV (Internet Protocol Television).

The display terminal device 300 includes a digital broadcast receiving tuner 306 for receiving a digital broadcast program.

The digital broadcast receiving tuner 306 can receive a digital broadcast program produced by a broadcasting company as a stereoscopic image in addition to a digital broadcast program of a general high-definition image. A digital broadcast program of a stereoscopic image may include a multi-angle stereoscopic image obtained by shooting a plurality of stereoscopic cameras as well as a single angle image. The stereoscopic digital broadcasting program outputs video and audio through the video output unit 307 and the audio output unit 309, respectively.

The remote controller 200 includes a key input unit 201, a remote control unit 202, and an infrared ray transmission unit 203.

When the viewer operates the key input unit 201 to output a key signal corresponding to each function, the remote controller control unit 202 transmits a control signal to the infrared ray transmission unit 203 according to the key signal, and the infrared ray transmission unit 203 transmits the infrared ray signal . Then, the display terminal device 300 interprets the infrared signal received through the infrared receiver 303 with the setting information stored in the memory 305, and performs the function set by the viewer.

The viewer can watch stereoscopic images provided by the display terminal device 300 by wearing stereoscopic glasses.

The stereoscopic spectacles unit 100 is mounted on stereoscopic glasses worn by viewers. The stereoscopic spectacles unit 100 may include a charging power source unit 110 that supplies a charging power source to independently drive each component without being supplied with external power. Of course, a method of supplying driving power from the outside through an electric wire can be applied, but the movement of the viewer wearing glasses can be restricted. Such stereoscopic glasses can be applied to a general eyeglass structure made up of an eyeglass frame, eyeglasses, and a pair of eyeglasses. Eyeglasses are shutter glasses filled with liquid crystal that can intercept or transmit light according to control signals, not vision adjustment.

If the video output unit 307 of the display terminal device 300 periodically outputs the left eye image and the right eye image, the stereoscopic spectacles unit 100 applied to the stereoscopic glasses of the time division scheme synchronizes with the alternate output of the stereoscopic images, (107) and (108) alternately. Information on the driving frequency for driving the shutter glasses 107 and 108 is supplied from the display terminal device 300 to the eyeglass driving unit 106. The information transmission is performed between the stereoscopic glasses unit 100 and the display terminal unit 300 The Bluetooth standard, which is one of the wireless communication methods, can be applied.

The stereoscopic glasses control unit 104 transmits synchronous information of the stereoscopic image output through the Bluetooth communication unit 303 at the request of the stereoscopic glasses unit 100, And outputs the drive control signal to the eyeglass driver 106 using the information. The eyeglass-driving unit 106 alternately drives the left-eye shutter glass 107 and the right-eye shutter glass 108. The viewer can watch the stereoscopic image by watching the left eye image or the right eye image outputted through the shutter glasses 107 and 108 which are alternately driven.

In a case where a multi-angle stereoscopic image created by a plurality of stereoscopic cameras and edited is watched through the display terminal device 300, a situation may occur in which the viewer wants to view another angle image. In this case, if the viewer can process the angle setting using the audio interface without directly manipulating the remote controller 200, it is possible to reduce the burden on the remote operation given to the viewer, .

The mode selection unit 101 selects a stereoscopic image mode or an angle setting mode. The mode selection unit 101 is implemented as a slide switch and can set a corresponding mode according to a switch operation position.

In the stereoscopic image mode, a digital broadcast program of a stereoscopic image provided by the display terminal device 300 is simply selected when viewing through stereoscopic glasses, whereas the angle setting mode is selected when a viewer Is selected when setting a desired angle image.

In the angle setting mode, the angle can be set by the viewer's voice.

The microphone 102 is mounted on the stereoscopic glasses and inputs a viewer's voice, and can be installed by being exposed to a spectacle frame or glasses legs.

The voice recognition unit 103 analyzes the viewer's voice signal inputted through the microphone 102 using the voice recognition module and provides the analysis result to the stereoscopic glasses control unit 104. [ The stereoscopic glasses control unit 104 recognizes the angle ID according to the characteristics and the signal pattern of the analyzed voice signal. At this time, the angle ID matched to the analysis result can be recognized using the information stored in the memory 105. [

In the angle setting mode, the display terminal device 300 displays on the screen of the stereoscopic image being viewed using the angle ID, the shooting object, and the angle information added to the digital broadcast program of the multi-angle stereoscopic image received by the digital broadcast receiving tuner 306 Angle guidance information is displayed as shown in FIG. 2 or FIG. Here, as shown in FIG. 4, the additional information is stored in the memory 305 as angle information including an angle ID for identifying an angle image, an object to be imaged, and an image capturing range and an angle.

2, the full screen 10 of the stereoscopic image may include a portrait image 1 11, a portrait image 2 12, a composite image 13, and a background image 14. Here, the portrait image 1 (11) and the portrait image 2 (12) are images in which the subject is a subject of close-up shooting as a person or an object, and the composite image 13 includes objects 11 and 12, The background image 14 is an image that can show a size larger than that of the appearing subjects 11 and 12. The background image 14 is a long-distance image photographed without surrounding the subject.

The full screen 10 may include angle setting guide information 21, 22, 23, 24 corresponding to these images 11, 12, 13, The angle setting guide information 21, 22, 23 and 24 is for identifying an angle image photographed by the stereoscopic camera at different angle angles and distances from the full screen 10, ID is displayed.

As another example of providing angle setting guide information, a separate guide screen 31 for providing angle setting guide information in the entire screen 30 may be included as illustrated in FIG. Providing of the guidance screen 31 is performed by the video output unit 307 under the control of the OSD control unit 308. [

The guide screen 31 may include the angle IDs A1 (A2), A3 (A4) and the corresponding coordinate points 33 together with the circular lines 32A and 32B indicating the photographing range. The angle IDs A1 and A2 located in the near circle line 32B correspond to the angle IDs A3 and A3 located in the far circle line 32A outside the near circle line 32B, ) A4 corresponds to a composite image and a background image.

In the angle setting mode, the viewer who is watching the entire screen 10 of FIG. 2 or the entire screen 30 of FIG. 3 can set the desired angle ID by voice.

In the angle setting mode, it is necessary to limit the noise input excluding the viewer's voice. That is, when the angle setting mode is set, the audio output of the digital broadcast program viewed by the display terminal device 300 is suspended.

When the viewer speaks the angle ID by voice, the viewer's voice signal is input to the voice recognition unit 103 via the microphone 102. [ The voice recognition unit 103 analyzes the voice signal input through the microphone 102 and provides the analyzed voice signal to the stereoscopic glasses control unit 104. [ The stereoscopic glasses control unit 104 transmits angle setting data corresponding to the analyzed angle ID to the display terminal device 300 via the Bluetooth communication unit 109. [ The display terminal device 300 recognizes the angle setting data received through the Bluetooth communication unit 302 and displays the angle image set by the viewer through the video output unit 2307 on the screen.

Hereinafter, a stereoscopic image viewing method based on speech recognition according to the present invention will be described with reference to the accompanying drawings.

5 is a flowchart for explaining the operation of the stereoscopic spectacles unit according to the present invention. 6 is a flowchart illustrating an operation of the display terminal apparatus according to the present invention.

The viewer selects one of the stereoscopic image mode and the angle setting mode using the mode selection unit 101 (150).

When the stereoscopic image mode is selected (YES in step 152), the mode setting data for setting the stereoscopic image mode is transmitted to the display terminal device 300 through the Bluetooth communication unit 109. Then, the display terminal device 300 transmits the synchronization information of the video output through the Bluetooth communication unit 302. The stereoscopic glasses control unit 104 outputs a control signal for driving the shutter glasses 107 and 108 to the eyeglass driver 106 in accordance with the synchronization information transmitted through the Bluetooth communication unit 109 (154). The left eye image transmitted through the shutter glass 107 driven by the eyeglass driving unit 106 and the right eye image transmitted through the shutter glass 108 are alternately provided to reproduce the stereoscopic image and the viewer wearing the stereoscopic glasses can watch the stereoscopic image (156).

If there is a request to end the viewing of the digital broadcast program, for example, when the power switch (not shown) is turned off (the example of 158), the driving of the shutter glasses 107 and 108 is stopped.

When the angle setting mode is selected using the mode selection unit 101 (YES in step 160), the Bluetooth communication unit 109 of the stereoscopic glasses unit 100 transmits mode setting data for requesting angle setting (step 162). The display terminal apparatus 300 can display the angle setting guide information for angle setting on the screen by outputting the entire screen 10 of FIG. 2 or the entire screen 30 of FIG. 3 to the video output unit 307 .

The viewer views the angle setting guide information provided on the full screen 10 (30) and speaks the angle ID for setting the desired angle image (164). The viewer's voice signal inputted through the microphone 102 And is provided to the speech recognition unit 103. [ Then, the voice recognition unit 103 analyzes the viewer's voice signal to recognize the angle ID desired to be viewed (166), and transmits the angle setting data corresponding to the angle ID via the Bluetooth communication unit (168).

If the viewer's voice for setting the angle is not inputted (NO at 164), the process returns to the start step (170) after waiting for a predetermined time.

6, a digital broadcast receiving tuner 306 receives a digital broadcast program of a corresponding channel according to a viewer command inputted through the remote controller 200 or the input unit 301 (350) The stereoscopic image is outputted through the video output unit 307 and audio is outputted through the audio output unit 309 (352).

The display controller 304 determines whether the stereoscopic spectacles unit 100 receives data for setting a stereoscopic image mode or receives an infrared signal control command from the remote controller 200 in the infrared reception mode Receives the infrared signal corresponding to the key input according to the operation of the controller 200, and performs the corresponding setting function. For example, channel change, volume adjustment, and the like (356). If the viewing is not terminated (NO in 358), the process returns to the starting step.

In the angle setting mode (example of 360), the display terminal device 300 displays angle setting guide information for requesting an angle setting on the screen (362), and the display terminal device 300 The audio output through the audio output unit 309 is suspended (364).

When the angle setting data for angle setting is received from the stereoscopic glasses unit 100 (366), the display terminal device 300 outputs the angle image set through the video output unit 307 according to the angle setting data And outputs the audio of the set angle image through the audio output unit 309 (368).

When the angle is not set by the viewer (No in 366), the display control unit 304 of the display terminal device 300 counts the waiting time (370), and when the waiting time passes the set time, the remote controller 200 (YES in 372), the process proceeds to step 356. If the waiting time has not passed the set time (NO in 372), the angle setting guide information is continuously displayed on the screen .

FIG. 7 is a block diagram of a stereoscopic image viewing system based on speech recognition according to another embodiment of the present invention, and FIG. 8 is a flowchart illustrating a stereoscopic image viewing method based on speech recognition according to another embodiment of the present invention.

As shown in Fig. 7, when a stereoscopic spectacles unit 100A in which synchronization information is not supplied from the display terminal unit 300A is applied, when a viewer wearing stereoscopic glasses sets an angle by voice, the stereoscopic spectacles unit 100A Transmits the angle setting data to the remote controller 200A using wireless communication. At this time, the Bluetooth communication unit 109 of the stereoscopic glasses unit 100A and the Bluetooth communication unit 211 of the remote controller 200A communicate with each other to transmit angle setting data. That is, the remote controller 200A transmits the infrared signal corresponding to the angle setting to the display terminal device 300A, and provides the angle image set by the viewer.

Upon receiving the mode setting data requesting the angle setting from the stereoscopic eye unit 100A, the remote controller control unit 212 transmits the corresponding infrared ray signal through the infrared ray transmitting unit 214. [ Then, the display control unit 304 receiving the angle setting request through the infrared receiving unit 303 displays the angle setting guide information on the entire screen 10 of FIG. 2 or the entire screen 30 of FIG. The viewer views the angle setting guide information and speaks the angle ID desired to set the angle by voice. The viewer's voice input through the microphone 102 is analyzed by the voice recognition unit 103 and the analysis result is provided to the stereoscopic glasses control unit 104. [

The stereoscopic glasses control unit 104 provides the angle setting data corresponding to the angle ID set according to the speech recognition result to the remote controller 200A through the Bluetooth communication unit 109. [

The remote controller control unit 212 receives the angle setting data through the Bluetooth communication unit 211 and transmits an infrared signal corresponding to the angle ID. Information on the infrared signal corresponding to the angle ID is stored in the memory 215. [

The display controller 304 analyzes the infrared signal received by the infrared receiver 303 and outputs a stereoscopic image desired to be viewed corresponding to the angle ID to the video output unit 307 and the audio output unit 309 Audio output.

In Fig. 7, the stereoscopic glasses unit 100A and the display terminal unit 300A mutually communicate with each other via the remote controller 200A. The remote controller 200 relays the angle setting request of the stereoscopic glasses unit 100A, It is possible to transmit the angle ID that is spoken by voice to the display terminal device 300A as an infrared signal.

The viewer who wears the stereoscopic glasses can set the angle by voice and view the desired angle image so that the viewer does not have to operate the remote controller 200A separately for setting the angle.

An operation of setting an angle by a viewer using the remote controller 200A will be described with reference to Fig.

When a key is input through the key input unit 213 of the remote controller 200A (YES in step 250), general remote control is performed. That is, the remote controller control unit 212 interprets the key signal according to the key input and transmits the infrared signal to the display terminal unit 300A according to the result of the interpretation (252). Accordingly, the display terminal device 300A performs channel change, screen color adjustment, volume adjustment, and the like in accordance with the infrared signal received from the remote controller 200A.

When the viewer wears the stereoscopic glasses and sets the angle setting mode using the mode selection unit 101, the stereoscopic glasses control unit 104 sends the mode setting data requesting the angle setting through the Bluetooth communication unit 109. [

The remote controller control unit 212 determines that there is a relay request for setting the angle through the Bluetooth communication unit 211 (YES in 254), and transmits the infrared signal requesting the angle setting via the infrared transmission unit 214 (256) . Then, the display terminal device 300A displays the angle setting guide information on the entire screen 10 (30). At this time, if the display control unit 304 is watching the digital broadcast program, the audio output which may interfere with the voice input can be stopped.

The viewer speaks the angle ID desired to be viewed while watching the angle setting guide information. The viewer's voice is input through the microphone 102 and the voice recognition unit 103 analyzes the viewer's voice signal and provides the analyzed information to the stereoscopic glasses control unit 104. [ Then, the stereoscopic glasses control unit 104 transmits the angle ID to the remote controller 200A through the blue communication communication unit 109. [

If it is determined that the remote controller 200A has received the angle setting data (YES in 258), the remote controller 200A transmits an infrared signal corresponding to the angle ID to the display terminal device 300A based on the information stored in the memory 215 (260) . Accordingly, the display terminal device 300A outputs the angle image set as the viewer's voice to the video output unit 307 and audio output through the audio output unit 309. [

The operation mode can be roughly classified into a general function mode for performing each function given to the portable terminal apparatus 400 and a mode for viewing a stereoscopic image. If it is not the stereoscopic viewing mode (No in 452), the corresponding function is performed according to the command input through the input unit 401 of the portable terminal device 400 (454).

The digital broadcasting receiving tuner 405 receives the digital broadcasting program 456 and transmits the digital broadcasting program to the video output unit 407 and the audio output unit 409 And outputs the video and audio of the broadcast program received through the audio interface 458 (458).

When the angle setting is requested (Yes in 460), angle setting guide information for guiding the angle setting is displayed on the screen (462), and the audio output is suspended (464) to prevent noise input other than the viewer's voice.

Then, when a viewer's voice for setting the angle is input (Yes in 466), the voice recognition unit 404 analyzes the viewer's voice signal input through the microphone 403 and provides the analyzed voice to the stereoscopic image controller 406. Then, the stereoscopic image controller 406 recognizes the angle ID desired to set the angle according to the analysis result (468). Then, according to the recognition of the angle ID, the stereoscopic image controller 406 controls the image and audio of the stereoscopic image, (407) and the audio output unit (409) (470).
