Abstract

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium having computer instructions to retrieve from a first high definition (HD) channel utilized for transporting two-dimensional media programs a first HD stereoscopic data stream, retrieve from a second HD channel utilized for transporting two-dimensional media programs a second HD stereoscopic data stream, and present a 3D HD imaging stream comprising the first and second stereoscopic data streams. Other embodiments are disclosed and contemplated.

First claim

What is claimed is:

1. A media processor, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising:
receiving a first high definition stereoscopic data stream on a first high definition channel of a communication network;
receiving a second high definition stereoscopic data stream on a second high definition channel of the communication network;
associating a first viewing apparatus and a second viewing apparatus with a presentation device having a plurality of pixel rows, wherein even pixel rows of the plurality of pixel rows have a first polarity, wherein odd pixel rows of the plurality of pixel rows have a second polarity, wherein the first polarity differs from the second polarity, wherein the first viewing apparatus is associated with the first high definition stereoscopic data stream and the second viewing apparatus is associated with the second high definition stereoscopic data stream, wherein each of the first viewing apparatus and the second viewing apparatus comprise a first polarized lens having the first polarity and a second polarized lens having the second polarity, and wherein the first polarized lens and the second polarized lens are adapted to simultaneously disable viewing or enable viewing during one or more periodic time slots of a plurality of periodic time slots;
transmitting a first synchronization signal to the first viewing apparatus and the second viewing apparatus, wherein the first synchronization signal assigns the first viewing apparatus to a first periodic time slot of the plurality of periodic time slots, and wherein the second viewing apparatus is assigned to a second periodic time slot of the plurality of periodic time slots;
directing the presentation device to present first and second image perspectives of the first high definition stereoscopic data stream during the first periodic time slot in alternating even and odd rows of the plurality of pixel rows, respectively, wherein the first viewing apparatus enables the first polarized lens and the second polarized lens for simultaneous viewing of the plurality of pixel rows during the first periodic time slot, and disables viewing through the first polarized lens and the second polarized lens during all other time slots except the first periodic time slot, and wherein a first three-dimensional (3D) stream is viewable by the first viewing apparatus at half resolution and a first illumination intensity only during the first periodic time slot;
directing the presentation device to present third and fourth image perspectives of the second high definition stereoscopic data stream during the second periodic time slot, wherein the second viewing apparatus is active during the second periodic time slot in alternating even and odd rows of the plurality of pixel rows, respectively, wherein the second viewing apparatus enables the first polarized lens and the second polarized lens for simultaneous viewing of the plurality of pixel rows during the second periodic time slot, and disables viewing through the first polarized lens and the second polarized lens during all other time slots except the second periodic time slot, wherein a second 3D stream is viewable by the second viewing apparatus at half resolution and a second illumination intensity only during the second periodic time slot, and wherein the first and the second high definition stereoscopic data streams have overlapping presentation schedules on the presentation device;
detecting an illumination change request from the first viewing apparatus, wherein the illumination change request is generated by a first light sensor of the first viewing apparatus;
responsive to the detecting, identifying a third periodic time slot from the plurality of periodic time slots as being an unused time slot;
directing the presentation device to further present the first high definition stereoscopic data stream in the third periodic time slot in alternating even and odd rows of the plurality of pixel rows, respectively, to increase an illumination of the first high definition stereoscopic data stream responsive to a first detection of the illumination change request from the first viewing apparatus;
updating the first synchronization signal to generate a second synchronization signal; and
transmitting the second synchronization signal to the first viewing apparatus and the second viewing apparatus, wherein the second synchronization signal assigns the first viewing apparatus to the first periodic time slot and the third periodic time slot of the plurality of periodic time slots, wherein the second viewing apparatus is assigned to the second periodic time slot of the plurality of periodic time slots, wherein the first viewing apparatus further enables the first polarized lens and the second polarized lens for simultaneous viewing of the plurality of pixel rows during the first periodic time slot and the third periodic time slot, and disables viewing through the first polarized lens and the second polarized lens during all other time slots except the first periodic time slot and the third periodic time slot, wherein the first 3D stream is viewable by the first viewing apparatus at the half resolution and a third illumination intensity only during the first periodic time slot and the third periodic time slot, and wherein the third illumination intensity exceeds the first illumination intensity.

2. The media processor of claim 1 , wherein the operations further comprise:
buffering the first and second high definition stereoscopic data streams;
aligning the first and second high definition stereoscopic data streams according to the first synchronization signal; and
transmitting an audio signal associated with the first high definition stereoscopic data stream to a viewing apparatus capable of viewing the first high definition stereoscopic data stream.

3. The media processor of claim 1 , wherein the operations further comprise:
directing the presentation device to emit a first set of light signals associated with a presentation of the first high definition stereoscopic data stream in the first periodic time slot; and
directing the presentation device to emit a second set of light signals associated with a presentation of the second high definition stereoscopic data stream in the second periodic time slot,
wherein the first and second periodic time slots have substantially non-overlapping intervals.

4. The media processor of claim 3 , wherein the first viewing apparatus and the second viewing apparatus each comprise a first optical element operable to enable the first set of the light signals to traverse the first optical element during a first time frame, wherein the first viewing apparatus and the second viewing apparatus each comprise a second optical element operable to enable the second set of the light signals to traverse the second optical element during a second time frame.

5. The media processor of claim 4 , wherein the first synchronization signal comprises synchronization data to mitigate a misalignment of the first and second high definition stereoscopic data streams due to transmission latency caused by the communication network.

6. The media processor of claim 1 , wherein the presentation device is operable to present portions of each of the first high definition stereoscopic data stream and the second high definition stereoscopic data stream with a plurality of polarizations.

7. A non-transitory, machine-readable storage medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, comprising:
retrieving from a first channel of a
