Video Analyzer for Masking Packet Loss Artifacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video content quality is compromised due to packet loss and bandwidth limitations, leading to artifacts and compression issues that degrade the user's viewing experience, which existing technologies fail to effectively address.
Innovation Solution
A content receiver system equipped with a video analyzer that inserts artifacts into video frames to mask packet loss and quantifies their effect, determining the quality of video content by analyzing perceptible edges and triggering responses when the quality falls below a threshold, and also addresses compression effects by analyzing bitrates and frame luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video content is transmitted over network connections subject to packet loss and bandwidth limitations, then video delivery can be achieved, but video quality deteriorates due to artifacts and compression
Solution Approach 1:
The patent converts the harmful effect of packet loss into a beneficial measurement opportunity. By intentionally inserting artifacts that simulate packet loss effects and measuring the video quality under these controlled conditions, the system transforms the problem of packet loss into a diagnostic tool. The video analyzer quantifies the impact of artifacts by comparing expected versus actual video quality, turning the harmful packet loss phenomenon into useful quality measurement data that can trigger appropriate recovery actions.
2Productivity
If video content is compressed to lower bit-rate for smooth playback, then playback continuity is improved, but video quality deteriorates due to blockiness artifacts
Solution Approach 1:
The patent implements a feedback mechanism where the video analyzer continuously monitors video quality metrics including blockiness artifacts. When the analyzer detects that compression-induced artifacts exceed acceptable thresholds, the system feeds this information back to trigger quality recovery actions. This feedback loop enables dynamic adjustment of quality parameters or activation of recovery mechanisms based on real-time artifact measurement, balancing playback continuity with quality maintenance.
3Reliability
If existing technologies are used to address packet loss and compression artifacts, then some quality issues can be mitigated, but the user's viewing experience remains degraded
Solution Approach 1:
The patent replaces traditional mechanical error correction methods with an intelligent measurement and response system. Instead of relying solely on conventional forward error correction or simple retransmission protocols, the system uses a video analyzer that quantifies artifact impact and triggers sophisticated quality recovery actions. This substitution of mechanical error handling with intelligent measurement-based response enables more effective mitigation of viewing experience degradation by adapting recovery strategies based on actual measured quality impact.
Data Source
AI summary
A content receiver and a method for controlling the same are provided. The content receiver, for example, may include, but is not limited to, a communication system configured to receive video content comprising a plurality of video frames from a content source, a processor configured to insert artifacts into one or more video frames when the video frame is subject to data loss, and a video analyzer configured to determine a quality of the video content by quantifying an effect of the inserted artifacts into the one or more video frames, and trigger at least one content receiver response when the quality of the video content is less than a predetermined threshold.
