BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display method and system, wherein when a 3D image is being played through a display device such as a theater screen, a computer monitor, a television receiver, a mobile phone liquid crystal screen, a game machine screen, or the like, a plurality of users may use their own preferences. Therefore, it is possible to simultaneously watch the video in 2D or 3D respectively, and when multiple types of video are being played through the display device, a plurality of users can select and watch each video type according to their preferences. A display method and system that can be used.

When watching a video through a display device such as a theater screen, a computer monitor, a television receiver, a mobile phone LCD screen, or a game console screen, all viewers of the display device can only watch the same video. . That is, for example, when a theater screen is playing a 3D video object on a theater screen, all viewers must wear 3D glasses or the like to watch the 3D video object and cannot view the same video image in 2D form. The reason is that the display device and the 3D glasses are set so that the left image can be viewed on the left side and the right image on the right side through the 3D glasses. This is because the left image and the right image are observed at the same time in both the left and right eyes without wearing the clear video. This is a problem that is common to all display apparatuses that play back 3D images in a polarization method, a shutter method, and an anaglyph method.

In addition, when the television receiver is set to play a video of a specific channel, all viewers must watch the video of the set channel and cannot simultaneously watch video of another channel on the same television receiver.

For example, the prior art, such as the Republic of Korea Patent (Registration No. 100757231), a method and device for simultaneously watching a plurality of channels in a DMB portable terminal, has a main screen and a secondary screen. The video is divided into screens, and video of a specific channel is played on the main screen, while video of other channels is played on the subscreen. However, this method also requires that all viewers watch the same type of screen divided into main screen and sub screen, and it is impossible to simultaneously view only the main screen or only the sub screen according to the viewer's preference. There is a disadvantage that the viewing feeling is reduced by separating the main screen and the sub-screen.

In order to solve the problems of the prior art, the viewer can select and watch only the desired video contents while simultaneously playing the multiple video contents in the 'Korean patent application (application number 10-1999-0051191) multi-image simultaneous playback device (currently disappeared)'. However, this technique has a problem of requiring a recording medium in which a plurality of kinds of images are alternately arranged one frame at a time, and a sound output means for selectively outputting only the sounds of the images selected by the image selection means. There is a problem in that it is not possible to confirm whether the technology is feasible because the implementation method is not described.

In addition, the 'Korean Patent (Application No. 10-2004-0081180) Multi-Video playback device and its method (currently no request for examination)' proposes a device that can play back multiple videos, but this technology must be able to reproduce two or more videos. There is a problem that the step of EMERGE alternately frame to produce a multi-image material, and the operation method and implementation method of the polarization shutter eyeglasses to view the multi-image image using a polarizing filter is not described, so it can be confirmed whether the technology is feasible. There is no problem.

In addition, the 'Korean Patent (Application No. 10-2004-0085890) 2 kinds of video playback device' suggests a device that can play back multiple video content, but it is necessary to make two types of video content in the radix field, the first image and the second field in the superior field. There is a disadvantage in that the recording medium is arranged so that there is no specific reference to the reproducing means for simultaneously reproducing the video recorded on the recording medium, and the audio output means for selectively outputting only the sound of the video selected by the video selection means. There is a problem in that it is not possible to confirm whether the technology is feasible because a specific implementation method is not mentioned.

In the example as shown in FIG. 2, the user adjusts the characteristics of the left and right glasses through the adjusting unit 230 of the watching assistance device 120 according to his / her preference, so that the left eye image is displayed on the left glasses 210 of the watching assistance device 120. ) To be transmitted only or the right eye image may be adjusted to be transmitted only to the right eyeglasses 220 of the watching assistance device 120. Alternatively, each user may adjust the left and right glasses of the watching assistance device 120 to have the same characteristics and transmit only the image having a specific characteristic among the left eye image or the right eye image. That is, in the case of a polarization type display, the left and right glasses of the watching auxiliary device 120 may be adjusted to transmit light having different polarization characteristics, or both glasses may be adjusted to transmit only light having different polarization characteristics. In the case of the shutter-type display, the shutters of both glasses are controlled so that the left and right glasses of the watching aid 120 alternately transmit light to each other so that the shutters of both glasses are opened or closed differently, or both glasses transmit the light at the same time. It is also possible to select the same opening / closing time. In the case of the color blocking method, the left and right glasses of the watching auxiliary device 120 may be adjusted to have different color blocking filters to block light of different colors, or both glasses may be adjusted to block light of the same color. For example, suppose a left eye image is displayed with vertical polarization and a right eye image is displayed with horizontal polarization. When the first user adjusts the polarization filter (or the lens) of the left and right glasses of the watching assistance device 120 to transmit the vertically polarized light to both the left and right eyes, the first user may view only the left eye image. That is, the first user can watch the 2D image. At the same time, when the second user allows the left eyeglasses 210 to transmit only the vertical polarization and the right eyeglasses 220 transmits only the horizontal polarization, the polarizing filter (or lens) of the left and right eyeglasses of the watching assistance device 120 The second user can watch the 3D image. In this manner, the first user and the second user can simultaneously watch 2D video and 3D video using the same display device. As described above, even in the time division method or the color blocking method, each user can watch different images in 2D or 3D in a similar principle to the polarization method.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains various modifications and variations from such descriptions. This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
