ABR Video Streaming White Spot Coverage System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in managing video streaming quality due to low data coverage and signal interference, which disrupts adaptive bitrate (ABR) streaming, especially in areas with inclement weather or structural interference, leading to a poor user experience.
Innovation Solution
A method that involves pre-caching advertisement clips and other content based on user demographics and location, using a video QoS-aware database to adapt to low radio quality conditions by switching to cached content when network bandwidth is available, allowing seamless playback and minimal modifications to existing infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video streaming is delivered over data networks in areas with low coverage or poor signal quality, then network infrastructure can be maintained, but user experience deteriorates due to insufficient bandwidth and signal interference
Solution Approach 1:
The system performs preliminary actions by detecting video outage areas through user feedback and building a database of these locations. Before users enter these areas, the system can prepare alternative content or notify users, preventing the harmful effect of video streaming failure in advance
Solution Approach 2:
The patent introduces an intermediary system comprising a video outage database, detection module, and content delivery mechanism that mediates between the user's video streaming request and the unreliable network conditions. This intermediary detects outage areas and provides alternative content delivery paths
2Reliability
If advertisement clips are pre-cached based on user demographics and location, then user experience is enhanced during outages, but device storage and network bandwidth are consumed
Solution Approach 1:
The system applies local quality by pre-caching advertisement content specifically in locations where video outages are detected and stored in a database. Instead of universally caching content everywhere, it targets specific geographic areas with poor coverage, optimizing storage usage while maintaining reliability where needed
Solution Approach 2:
The system enables self-service by allowing users to provide feedback about video outages they experience, which automatically gets added to the outage database. This user-generated data drives the system's ability to pre-cache content in the right locations without requiring extensive manual surveying
3Productivity
If ABR streaming is used to adapt to varying network conditions, then bandwidth efficiency is improved, but video quality consistency deteriorates in low coverage areas
Solution Approach 1:
The system performs preliminary detection of video outage areas and builds a database of these locations before users encounter them. This advance knowledge allows the system to prepare alternative content delivery strategies, maintaining video quality consistency by switching to pre-cached content or notifying users before quality degradation occurs
Solution Approach 2:
The patent implements a feedback mechanism where users report video outage experiences, and this feedback is used to update the video outage database. The system continuously learns from user feedback to improve its detection accuracy and content delivery decisions, ensuring consistent video quality over time

AI summary
A scheme for managing ABR streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless UE device executing an ABR client application is in a radio white spot area, the current ABR streaming session may he suspended at a particular segment. Thereafter, playback of other content locally cached at the wireless UE device may be commenced in lieu of the ABR media segments. When the wireless UE device exits the radio white spot area, the ABR streaming session may be resumed from a point adjacent to the particular segment where the ABR streaming session was suspended.
