Video Quality Assessment for Interlacing and Blocking Detection

The patent applies preliminary action by performing quality detection and applying improvement techniques (such as de-interlacing and blocking removal) to video data before it is served to users. The system proactively identifies and corrects quality issues in uploaded videos during the transcoding process, ensuring that degraded video artifacts are eliminated in advance rather than reacting to user complaints later.

The patent implements self-service by enabling the video processing system to automatically detect quality issues and apply corrections without requiring manual intervention. The quality detection and improvement processes are automated through algorithms that analyze video data for interlacing and blocking artifacts, then apply appropriate processing techniques autonomously, reducing the need for complex manual quality control workflows.

The patent applies local quality by selectively processing only the portions of video data that contain quality issues. Rather than uniformly processing entire videos, the system identifies specific regions or segments affected by interlacing or blocking artifacts and applies improvement techniques only to those affected areas, thereby reducing overall processing time while maintaining quality improvements where needed.

The patent converts the harmful effect of interlacing into a benefit by detecting interlaced video and applying de-interlacing techniques that transform the problematic alternating field structure into a progressive scan format. This conversion eliminates combing artifacts and interline twitter while maintaining smooth playback, turning the originally harmful interlaced structure into a visually beneficial progressive display.
