Abstract:
The present invention uses concentrated pixels to enable pixels from three video streams to side by side concurrently occupy the space that would normally be taken by one video pixel. In operation, visible light from each of the three concentrated pixels is then directed by an optic into a respective segment of the user space. A monitor comprised of arrays of said concentrated pixels each emitting visible light which is directed by optics into three distinctive users spaces. Users within each respective user space see unique video steams across the entire surface of the video monitor which are not visible to those in other respective user spaces. Using the techniques described, two or more video streams can be displayed concurrently on one video monitor concurrently. Examples of CRT, projection, and LCD embodiments are described.

Description:
BACKGROUND FIELD OF INVENTION  
         [0001]    Modem video monitors incorporate many technologies and methods for providing high quality video to users. Nearly every household in the United States has one or more video monitors in the form of a television or a computer monitor. These devices generally use technologies such as Cathode Ray Tubes (CRT) tubes, Liquid Crystal Displays (LCD), or Digital Micromirror Devices (DMD) projection in one way or another. Large monitors offer the advantage of enabling many users to see the video monitor simultaneously as in a living room television for example. Often video users do not want to view the same video streams as one another.  
           [0002]    The prior art describes some attempts to enable multiple viewers to see different video streams concurrently on the same monitor. These are generally drawn to wearing glasses that use polarization or light shutters to filter out the unwanted video stream while enabling the desired video stream to pass to the users&#39; eyes. No prior art provides a technique to enable multiple viewers to view separate video streams concurrently with the unaided eye.  
           [0003]    The present invention provides a significant step forward for video monitors. The present invention describes multiple embodiments which enable multiple video streams to be displayed on the same video monitor concurrently. Each embodiment describes the concurrent presentation and separation of three video streams by providing a three fold increase in pixels, said pixels including side by side concurrent pixel segments from the three video streams wherein post pixel optics cause the three respective video streams to be visible in a physically segmented user space. The result is that three groups of users can sit in three viewing zones wherein people in each of the zones can view different video streams on the same monitor concurrently.  
         BACKGROUND-DESCRIPTION OF PRIOR INVENTION  
         [0004]    Many display screens have been described and practiced in the prior art. Modern video monitors incorporate many technologies and methods for providing high quality video to users. Nearly every household in the United States has one or more video monitors in the form of a television or a computer. These devices generally use technologies such as Cathode Ray Tulbes (CRT) tubes, Liquid Crystal Displays (LCD), or Digital Micromirror Devices (DMD) in one way or another. Large monitors offer the advantage of enabling many users to see the video monitor simultaneously as in a living room for example. Often video users do not want to view the same video streams as one another.  
           [0005]    The prior art describes some attempts to enable multiple viewers to see different video streams concurrently on the same monitor. These are generally drawn to wearing glasses that use polarization or light shutters to filter out the unwanted video stream while enabling the desired video stream to pass to the users&#39; eyes. U.S. Pat. No. 6,188,442 Narayanaswami being one such patent wherein the users where special glasses to see their respective video streams. U.S. Pat. No. 2,832,821 DuMont does provide a device that enables two viewers to see multiple polarized images from the same polarizing optic concurrently. DuMont however also requires that the viewers use separate polarizing screens as portable viewing aids similar to the glasses. DuMont further requires the expense of using two monitors concurrently. No prior art provides a technique to enable multiple viewers to view separate video streams on the same monitor concurrently with the unaided eye as does the present invention.  
         BRIEF SUMMARY  
         [0006]    The invention described herein represents a significant improvement for the users of video monitors. Heretofore a large family size television for example could only carry one video stream on its entire surface at any given time. Anyone not interested in watching the same video stream was required to use a television in another room or in the case of “picture in picture” to view the video stream on a smaller portion of the same monitor. Likewise if a family member wanted to use the computer or video game, they would have to go to a separate computer or gaming station with a monitor. The present invention enables multiple users to use one video monitor concurrently while each views completely different video content concurrently whether television video, computer video, gaming video, or some other form of video.  
           [0007]    The present invention uses concentrated pixels to enable pixels from three video streams to side by side concurrently occupy the space that would normally be taken by one video pixel. In operation, visible light from each of the three concentrated pixels is then directed by an optic into a respective segment of the user space. A monitor comprised of arrays of said concentrated pixels each emitting visible light which is directed by optics into three distinctive users spaces. Users within each respective user space see unique video steams across the entire surface of the video monitor which are not visible to those in other respective user spaces. Using the techniques described, two or more video streams can be displayed concurrently on one video monitor concurrently. Examples of CRT, projection, and LCD embodiments are described.  
           [0008]    Thus the present invention offers a significant advancement in the functionality of video monitors.  
         OBJECTS AND ADVANTAGES  
         [0009]    Accordingly, several objects and advantages of my invention are apparent. It is an object of the present invention to provide a monitor which enables multiple viewers to experience completely different video streams simultaneously. This enables families to spend more time together while simultaneously independently experiencing different visual media or working on different projects in the presence of one another. Energy can be saved by concentrating visible light energy into narrower user space when just one person is using a monitory. Likewise when multiple users use the same monitor instead of going into a different room, less electric lighting is required. Also, by enabling one monitor to operate as multiple monitors, living space can be conserved which would otherwise be cluttered with a multitude of monitors.  
           [0010]    It is an advantage that the present invention doesn&#39;t require special eyewear, eyeglasses, goggles, or portable viewing devices as does the prior art.  
           [0011]    Further objects and advantages will become apparent from the enclosed figures and specifications.

         [0082]    Thus the reader will see that the Multiple Bit stream Directional Video Monitor Apparatus and Process of this invention provides a novel unanticipated, highly functional and reliable means for distributing multiple video streams to segmented user spaces such that users within each respective space can video distinct video streams.  
         [0083]    While my above description describes many specifications, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of a preferred embodiment thereof. Many other variations are possible. Many types of video monitors are well known. For example, many techniques for projecting images are well known and could be used by one skilled in the art to physically segment multiple video streams according to the present invention. Many optical elements and combinations thereof are possible. It should be understood that the term “video monitor” refers to a television screen, a computer screen, a video game screen, or device which substantially provides images to a user.
