Multi-Viewer Video Stream Segmentation and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems do not provide an easy means for multiple individuals in an enclosed environment to control and view different content from a single presentation device, such as a television or computer, without the need for separate devices.
Innovation Solution
A system that generates a combined video stream by time-slicing or polarizing video content from multiple sources, allowing each viewer to use a handheld device as a remote control to adjust their content while the other content remains unaffected, using wearable devices to filter out unwanted streams and presenting audio separately to each viewer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple content streams are presented on a single presentation device, then multiple viewers can view different content simultaneously, but the device complexity and resource usage increase
Solution Approach 1:
The video stream is segmented into multiple independent content streams using time-slicing technology. Each content stream is assigned to a specific viewer through wearable devices, allowing simultaneous presentation of multiple contents on a single display device without increasing its complexity
Solution Approach 2:
Wearable devices serve as intermediary components between the presentation device and viewers. These devices receive control signals from handheld devices, manage content stream assignment, and enable selective viewing through optical filtering, thereby managing the complexity of multi-content presentation
2Ease of operation
If each viewer controls their own content independently, then individual content control is achieved, but the control system complexity increases
Solution Approach 1:
The handheld device is designed as a universal controller that can control any content stream assigned to the associated viewer. The control signals are processed by the wearable device, which routes them to the appropriate content stream, allowing a single control interface to manage multiple contents without increasing control system complexity
Solution Approach 2:
The system implements feedback mechanisms where the wearable devices communicate viewer preferences and control signals back to the content processing system. This allows automatic adjustment of content streams based on viewer interactions, simplifying individual content control while managing system complexity through automated feedback loops
3Loss of information
If wearable devices with polarizing filters are used, then content stream separation is achieved, but the device complexity and cost increase
Solution Approach 1:
The system uses polarizing filters in wearable devices that selectively block or transmit light based on polarization orientation. This optical filtering mechanism separates content streams by encoding different contents with different polarization states, achieving content stream separation through simple optical properties rather than complex electronic filtering
Solution Approach 2:
The content streams are modulated with different temporal patterns (time-slicing sequences) that correspond to specific wearable device configurations. By changing the temporal parameters of the video signal and matching them with the response characteristics of the wearable devices, the system achieves content separation without requiring complex filtering mechanisms in the wearable devices
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables multiple viewers to independently control and view different content on a single presentation device without increasing resource usage, reducing the need for multiple devices and minimizing resource consumption.
Implementation Method 1
The wearable device comprises a polarizing filter that filters out one content stream while allowing the other content stream to pass through
Data Source
AI summary
In example embodiments, a system and method for presenting multiple content (e.g., programs) on a single presentation device to a plurality of viewers is provided. The method comprises causing presentation of a combined video stream on the single presentation device. The combined video stream combines video data for at least a first video content of a first content stream and a second video content of a second content stream. The first video content is viewable by a first viewer and the second video content is viewable a second viewer. A control signal is received from a handheld device of the first viewer that indicates an action to be performed on the first video content. The combined video stream is modified to cause the action to be performed on the first video content. The adjusting of the combined video stream has no effect on the display of the second video content.
