Graphics-Aware Video Encoding for Wireless Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video encoding techniques, such as AVC and HEVC, are inefficient for encoding computer-generated content like desktop and gaming content in wireless display systems, as they are designed for naturally captured video and do not optimize power, performance, and video quality for graphics-based content.
Innovation Solution
Collecting graphics properties from a graphics composition system to determine encode settings for each frame, such as geometry, layer types, and update indicators, allowing for intra mode, skip mode, and high-quality encoding settings to be applied, enabling efficient encoding and transmission of graphics-based video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If AVC or HEVC encoding standards are used for wireless display, then video quality and resolution are improved, but power consumption and processing complexity increase
Solution Approach 1:
The patent changes the encoding parameters dynamically based on content type detection. For graphics-based content, it uses simplified encoding parameters (lower compression complexity) compared to natural video, thereby reducing power consumption while maintaining adequate video quality for the specific content type
Solution Approach 2:
The patent segments the video content into different types (graphics-based vs. natural video) and applies different encoding strategies to each segment. This allows optimized power consumption for graphics content while preserving high quality encoding for natural video segments
2Manufacturing precision
If AVC or HEVC encoding standards are used for wireless display, then video quality and resolution are improved, but processing complexity increases
Solution Approach 1:
The patent modifies encoding parameters based on content type. For graphics-based content, it reduces processing complexity by using simplified encoding paths and fewer processing steps, while maintaining sufficient video quality for the application
Solution Approach 2:
The patent divides content into segments (graphics vs. natural video) and applies different processing complexities to each. Graphics segments receive simplified processing while natural video segments receive full complex encoding, optimizing overall system performance
3Productivity
If standard video encoding is applied to graphics-based content, then encoding is performed, but encoding efficiency and power consumption are suboptimal
Solution Approach 1:
The patent performs preliminary content type analysis before encoding. By detecting whether content is graphics-based or natural video in advance, it can pre-select the appropriate encoding mode, avoiding unnecessary complex processing for graphics content and improving encoding efficiency while reducing power consumption
