Solution Overview
Problem
Existing communication networks face challenges in efficiently signaling and delivering stereoscopic three-dimensional video content to client devices, particularly in wireless networks, due to variations in device capabilities and rendering requirements.
Innovation Solution
The proposed solution involves methods and systems for signaling stereoscopic three-dimensional video content capabilities of client devices in communication networks. This includes device capability exchange signaling, where devices communicate their decoding and rendering capabilities to media servers, allowing for optimized content adaptation and delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device capability exchange signaling is implemented to adapt content to specific device capabilities, then the quality of experience for users is enhanced, but the device complexity and network signaling overhead increase
Solution Approach 1:
The patent applies preliminary action by having client devices proactively signal their 3-D video capabilities (decoding formats, rendering capabilities, display specifications) to media servers before content delivery. This advance capability exchange allows the server to pre-adapt content to match device specifications, ensuring optimal quality of experience while avoiding runtime negotiations that would increase signaling complexity during actual content delivery
Solution Approach 2:
The patent implements parameter changes by standardizing capability parameters into defined categories (decoding capabilities, rendering capabilities, display specifications) with specific enumerated values. This parameterization approach allows devices to convey complex capability information through structured, standardized parameter sets rather than unstructured detailed descriptions, reducing signaling overhead while maintaining comprehensive capability representation
2Reliability
If content is adapted to specific device capabilities, then the quality of experience is improved, but the network resources and processing overhead increase
Solution Approach 1:
The patent applies local quality by adapting content delivery to match specific device capabilities rather than using a one-size-fits-all approach. The media server analyzes individual device capability parameters (such as supported decoding formats, rendering capabilities, and display specifications) and delivers content in the optimal format for each specific device. This targeted adaptation improves quality of experience for each device while avoiding the unnecessary processing and network resources that would be consumed by delivering all possible content formats to every device
Solution Approach 2:
The patent implements partial action by having devices signal only the specific 3-D video capability parameters that are relevant to their functionality, rather than reporting all possible device attributes. The capability exchange focuses on essential parameters (decoding formats, rendering capabilities, display specifications) needed for 3-D video delivery, omitting unrelated device characteristics. This selective signaling reduces network overhead and processing requirements while still enabling effective content adaptation
