Abstract

Techniques are described herein for supporting independent viewer tailoring of same media source content via a common 2D-3D display. A first independently controllable version of video content is caused to be delivered to a first region of a screen. A second independently controllable version of the video content is caused to be delivered to a second region of the screen. The first region and the second region overlap at least in part. For example, the first and second independently controllable versions may be simultaneously displayed such that the first independently controllable version is displayed for a first viewer but not for a second viewer and such that the second independently controllable version may be displayed for the second viewer but not for the first viewer.

Claims

1. A display system that supports a screen and video content for a first viewer and a second viewer, the display system comprising:

first interface circuitry that receives the video content;

second interface circuitry that supports a communication pathway to the screen; and

processing circuitry that delivers via the second interface circuitry both a first version of a designated frame sequence of the video content that is independently controllable during playback to a first region of the screen and a second version of the designated frame sequence of the video content that is independently controllable during playback to a second region of the screen, the first region and the second region overlapping at least in part, and the delivery supporting simultaneous display by the screen of both the first version of the designated frame sequence for the first viewer but not the second viewer and the second version of the designated frame sequence for the second viewer but not the first viewer, the first version of the designated frame sequence and the second version of the designated frame sequence being based on same media source content, and the first version of the designated frame sequence being independently controllable during playback without affecting the second version of the designated frame sequence, and the second version of the designated frame sequence being independently controllable during playback without affecting the first version of the designated frame sequence.

2. The display system of claim 1, further comprising:

a control system through which both the first viewer can control the first version of the designated frame sequence, and the second viewer can control the second version of the designated frame sequence.

3. The display system of claim 2, wherein the control by the control system comprising a playback control.

4. The display system of claim 1, further comprising:

audio circuitry that delivers both a first audio output corresponding to the first version of the designated frame sequence and a second audio output corresponding to the second version of the designated frame sequence.

5. The display system of claim 1, wherein the processing circuitry is configured to deliver, via the second interface circuitry, a single version of the video content based at least in part on the first version of the designated frame sequence and the second version of the designated frame sequence being substantially in synchrony.

6. The display system of claim 1, wherein the first version of the designated frame sequence includes supplemental content that is not included in the second version of the designated frame sequence.

7. Media circuitry that supports visual presentation of a video frame sequence on a screen assembly, the visual presentation being viewed by a first viewer and a second viewer, the media circuitry comprising:

first interface circuitry that receives the video frame sequence;

second interface circuitry that communicatively couples with the screen assembly;

control circuitry communicatively coupled to both the first interface circuitry and the second interface circuitry; and

the control circuitry delivers both a first frame sequence and a second frame sequence from same media source content via the second interface circuitry to the screen assembly for simultaneous display in at least a partially overlapping area of the screen assembly, the first frame sequence being delivered to produce a first visual presentation that is independently controllable during playback for the first viewer but not for the second viewer, the second frame sequence being delivered to produce a second visual presentation that is independently controllable during playback for the second viewer but not for the first viewer, each of the first frame sequence and the second frame sequence being based at least in part on the video frame sequence, and the first visual presentation being independently controllable during playback by the first viewer without affecting the second visual presentation and the second visual presentation being independently controllable during playback by the second viewer without affecting the first visual presentation.

8. The media circuitry of claim 7, further comprising:

17. The method of claim 15, further comprising:
