Media Processor Adapting View Perspective via Time-Division Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media presentation systems lack the ability to adapt media content presentation based on the position of viewing apparatuses, leading to inefficiencies in multi-user scenarios where different users may require different viewing perspectives or resolutions, such as 2D or 3D, without disrupting others' viewing experiences.
Innovation Solution
A media processor system that detects the position of viewing apparatuses and assigns periodic time slots for presenting media programs with specific viewing perspectives, using techniques like time-division multiplexing (TDM) or space-division multiplexing (SDM) to ensure each user receives the appropriate media content and audio signals tailored to their perspective, allowing for simultaneous viewing of multiple programs with overlapping schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single media program is presented to all users simultaneously, then system complexity is reduced and ease of operation is improved, but adaptability to different user viewing perspectives and positions deteriorates
Solution Approach 1:
The patent segments the media content into multiple perspective-specific streams (e.g., first perspective, second perspective) and assigns each to different time slots or spatial channels. The presentation device divides the single display into multiple viewing zones, allowing different users at different positions to receive customized content without requiring complex individual device customization for each user.
Solution Approach 2:
The patent implements periodic switching between different perspective presentations using time-division multiplexing. The system alternates between presenting media content from different perspectives in periodic time slots, synchronized with the users' viewing apparatus (e.g., shutter glasses), enabling each user to receive the appropriate perspective during their assigned time windows while sharing a single display resource.
2Adaptability or versatility
If media content is customized for each user's viewing position, then adaptability and user experience are improved, but bandwidth utilization and system resource consumption increase
Solution Approach 1:
The patent merges multiple perspective-specific media streams into a single transmitted signal that carries information for multiple users simultaneously. By combining the content streams and using a shared presentation device, the system delivers customized content to different users without requiring separate transmission channels for each user, thus reducing overall bandwidth consumption while maintaining adaptability.
Solution Approach 2:
The system uses periodic time-division multiplexing to transmit different perspective content in alternating time slots over a shared communication channel. This allows the system to deliver customized media content to multiple users sequentially rather than simultaneously, optimizing bandwidth utilization by reusing the same transmission resources for different users at different times while maintaining the illusion of continuous customized delivery.
3Adaptability or versatility
If multiple viewing perspectives are presented simultaneously, then adaptability to multi-user scenarios is improved, but device complexity and control mechanisms increase
Solution Approach 1:
The patent implements automatic detection of user position and automatic assignment of appropriate perspective content without requiring manual user input or complex control interfaces. The system self-adjusts by detecting which user is at which position and automatically presenting the corresponding media perspective to each user, simplifying operation while maintaining high adaptability to multi-user scenarios.
Solution Approach 2:
The system uses feedback from position detection mechanisms (e.g., sensors, cameras, or user input devices) to automatically adjust which perspective content is presented to which user. This closed-loop control allows the system to respond dynamically to changing user positions and preferences, maintaining ease of operation by eliminating manual configuration while achieving sophisticated multi-user adaptability.
4Loss of energy
If time-division multiplexing is used to assign different perspectives to different users, then bandwidth utilization is improved, but measurement precision of user position and timing synchronization requirements increase
Solution Approach 1:
The patent pre-establishes the relationship between user positions and perspective assignments before media presentation begins. The system detects user positions in advance and pre-assigns appropriate perspectives and time slots to each user, eliminating the need for continuous high-precision position monitoring during content delivery. This preliminary configuration reduces real-time measurement requirements while maintaining bandwidth efficiency through time-division multiplexing.

AI summary
A system that incorporates teachings of the present disclosure may include, for example, a non-transitory computer-readable storage medium having computer instructions to detect a first position of a viewing apparatus, wherein the viewing apparatus enables viewing of media programs, obtain a media program in a first viewing perspective that conforms to the first position, present the media program with the first viewing perspective for viewing by way of the viewing apparatus, and transmit to the viewing apparatus a first audio signal corresponding to the first viewing perspective. The storage medium can also have computer instructions to detect that the viewing apparatus has moved to a second position, obtain the media program in a second viewing perspective according to the second position, and present the media program with the second viewing perspective for viewing by way of the viewing apparatus. Other embodiments are disclosed and contemplated.
