Remote Web Content Rendering via Layered Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for rendering Web content on television devices consume significant power and bandwidth, and often compromise the quality of the content due to limitations in resolution and compression, resulting in reduced quality when displayed on TVs.
Innovation Solution
The method involves generating and transmitting content layers, including drawing commands and encoded images, from a source device to a television device, allowing for efficient and high-quality rendering of Web content without the need for extensive compression, thereby maintaining the original quality of the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional video compression is used to transmit Web content from source device to television device, then bandwidth consumption is reduced, but the quality of the Web content displayed on television is significantly compromised
Solution Approach 1:
The patent segments the Web content transmission into multiple content layers, each representing different quality levels or resolutions. This allows the system to transmit only the necessary layer(s) based on available bandwidth and display capabilities, avoiding full compression while optimizing bandwidth usage. The layered structure enables selective transmission of high-quality content when bandwidth permits.
Solution Approach 2:
The patent changes the transmission parameter from compressed video streams to uncompressed or lightly compressed content layers. By altering the compression parameter from high compression (conventional approach) to low or no compression (layered approach), the system maintains content quality while managing bandwidth through intelligent layer selection and transmission strategies.
2Productivity
If conventional video compression is used to transmit Web content, then transmission efficiency is improved, but the resolution and quality of text and other Web content are reduced
Solution Approach 1:
The patent divides content into separate layers that can be transmitted independently. Text layers and image layers are segmented from video layers, allowing text to be transmitted at full resolution without being subject to video compression artifacts. This segmentation enables high-resolution text transmission while maintaining overall transmission efficiency through selective layer delivery.
Solution Approach 2:
The patent applies different quality levels to different parts of the content by using localized layer transmission. High-resolution layers are transmitted for static content like text and images, while lower-resolution or compressed layers are used for dynamic video content. This local quality approach ensures text remains sharp and readable while optimizing bandwidth for moving image content.
3Adaptability or versatility
If the source device captures and re-compresses Web content for transmission to television device, then the content can be displayed on TV, but power consumption and bandwidth usage increase significantly
Solution Approach 1:
The patent performs preliminary segmentation of Web content into content layers at the source device before transmission. By pre-processing content into reusable layers rather than continuously capturing and re-compressing video, the system reduces the computational power required during transmission and display. The layers can be efficiently transmitted and assembled at the television device without intensive real-time compression.
Solution Approach 2:
The patent creates digital copies of content in the form of content layers that can be transmitted and reconstructed at the television device. Instead of continuous video capture and compression, the system uses static layer copies that represent different aspects of the content (text, images, video), reducing the power required for continuous processing while maintaining display adaptability.
