Video Frame Bearer Path Differentiation for Emergent Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content delivery systems fail to differentiate between pre-fetch and emergent frames, leading to inconsistent quality of service for panoramic and 360-degree video content, as both types of frames are often transmitted over the same bearer path, resulting in potential delays and poor user experience when the user's perspective changes unexpectedly.
Innovation Solution
The system differentiates between pre-fetch and emergent frames by transmitting pre-fetch frames over a default bearer path and emergent frames over a dedicated bearer path, ensuring prioritized delivery of emergent frames to maintain seamless video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pre-fetch frames and emergent frames are transmitted over the same bearer path, then device complexity is reduced, but quality of service for emergent frames deteriorates causing video stalls
Solution Approach 1:
The patent segments video frames into two categories: pre-fetch frames and emergent frames. Pre-fetch frames are transmitted over a default bearer path, while emergent frames are transmitted over a dedicated bearer path. This segmentation allows the system to optimize resource allocation for different frame types, ensuring that critical emergent frames receive prioritized transmission resources to prevent video stalls.
Solution Approach 2:
The patent applies different quality of service parameters to different frame types. Emergent frames are allocated higher priority and dedicated bandwidth on a separate bearer path, while pre-fetch frames use standard transmission resources. This local quality differentiation ensures that critical frames receive the necessary resources for timely delivery without unnecessarily complicating the transmission of non-critical frames.
2Reliability
If dedicated bearer path is used for emergent frames, then quality of service is improved, but device complexity increases
Solution Approach 1:
The system establishes a dedicated bearer path in advance for transmitting emergent frames. By pre-configuring this dedicated transmission path, the system ensures that when emergent frames need to be transmitted, an optimized pathway is already available, reducing latency and improving reliability without requiring complex real-time path selection.
Solution Approach 2:
The patent introduces a bearer path management intermediary that handles the complexity of managing multiple bearer paths. This intermediary component abstracts the complexity of dedicated bearer path management, allowing the rest of the system to benefit from improved emergent frame delivery without directly dealing with the complexity of path management.
