Definitions
- the set top box receives two video inputs of the same frame rate, type and format. Every frame, from each of both video inputs is encoded and buffered in memory. At decoding the frames are base time synchronized to a common clock. After each frame the same clock switches output to the other decoder so that frames are output in an alternating pattern. While the combined streams equals the original frame rate, each video stream is played out at half its original frame rate. The output is played out at the same frame rate at the same video specifications required to display either of the original video inputs.
- the associated audio is transmitted to earphones fitted in a pair of glasses worn by the viewer.
- the glasses have a electronic shutter that is synchronized to block the view of non-associated video but open to permit view of the video associated with the audio.
- Shutter synchronization of the glasses is sent from the set top box achieved via the signal associated with either the audio or the video display or a separate communications channel or as in the examples below an IRT infrared transmitter.
- the Multi-Viewer Display is the incorporation of the invention within the display unit.
- Multi-View Mode All frames of from multiple video inputs are buffered, re- synchronized and interleaved and into a single output stream that can be displayed on a single higher frame rate display than the video inputs.
- the associated audio is transmitted to an earphone in a pair of glasses worn by the viewer. These glasses have a shutter that is synchronized to block the view of non-associated video but open to permit view of the video associated with the audio.
- Each video input is viewed at the original frame rate since the display is capable of operating at multiples higher than the original frame rate each viewer.
- Shutter synchronization of the glasses is achieved via the signal associated with the audio, video display or separate channel. See Figure 3 "Multi-Viewer Display Framing and Timing"
- 3D mode the glasses synchronize with the left eye video input and the right eye with right eye video input creating a 3D effect.
- This patent is distinguished from other 3D patents in that this is achieved using existing standard video broadcast systems on existing standard receivers. There is no requirement to modify existing broadcast or receiver technologies and equipment, apart from the set top box and glasses described herein.
- High Security displays inject masking video and encrypt variations into the video frame rate and interleave pattern to provide high security displays that can only be viewed by permitted personnel with decrypting glasses.
- Variations in frame rate and interleave pattern can be achieved by 1 ) modifying the display monitor with specialized hardware built into the display or 2) by specialized chipset built into the graphics adapter or 3) by computer software.
- 3D Mode is also available for high security displays with high frame refresh rates.
- Low frame refresh rate displays of 30Hz or lower would not produce broadcast quality viewing, as each eyes frame rate would be approximately 10 frames per second.
- Frames from multiple films within a specially adapted film projector are interleaved projected onto a single screen at a frame rate that equals the sum of the frame rates of each film combined.
- the associated audio is transmitted to an earphone in a pair of glasses worn by the viewer. These glasses have a shutter that is synchronized to block the view of non-associated film projection but open to permit view of the film projection associated with the audio. Each film projection is viewed at the original frame rate since the projector is capable of operating at the sum of the frame rate of the films combined. Shutter synchronization of the glasses is achieved via the signal associated with the audio, film projection or separate channel.
- 3D mode is claimed for films shot using two regular 2D film cameras on two separate reels suitable for 3D screening using this patent without further modifications to format.
