Adaptive Content Service System for Terminal-Specific Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia portal service systems face high expenses and limited user capacity due to the need for transcoding content for various terminals, which increases exponentially with the number of terminals and connected users, limiting simultaneous connections based on processing capacity.
Innovation Solution
An apparatus and method that analyze device information from terminals to determine a service profile, selecting and providing optimized content and services based on characteristics such as screen size, resolution, and speaker type, allowing for adaptive content delivery without the need for extensive transcoding, using a smart agent and service manager to manage content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transcoding is performed for each terminal type, then content compatibility across various terminals is improved, but system expenses and processing complexity increase exponentially
Solution Approach 1:
The patent segments the transcoding process by creating separate transcoding managers for different content types (video transcoding manager, audio transcoding manager, image transcoding manager). Each manager handles specific format conversions, dividing the complex transcoding task into manageable segments that can be processed independently and efficiently.
Solution Approach 2:
The system performs preliminary action by pre-processing content into multiple formats and storing them in advance. The transcoding managers convert source content into various target formats and store these pre-transcoded versions, so that when terminals request content, the appropriate pre-processed format can be delivered immediately without real-time transcoding delays.
2Productivity
If transcoding capacity is increased to support more terminals, then user capacity increases, but system expenses increase exponentially
Solution Approach 1:
The patent implements universality by designing a content delivery system that serves multiple terminal types simultaneously through a standardized architecture. The service manager and transcoding managers handle various content types (video, audio, image) and deliver them to different terminals (mobile phones, PDAs, PCs, set-top boxes) using a unified process, allowing one system to efficiently serve diverse users without requiring separate infrastructure for each terminal type.
3Adaptability or versatility
If real-time transcoding is performed for each user request, then content optimization for individual terminals is improved, but processing time and system load increase
Solution Approach 1:
The system performs preliminary action by pre-processing content into multiple formats and storing them in advance. The transcoding managers convert source content into various target formats and store these pre-transcoded versions, so that when terminals request content, the appropriate pre-processed format can be delivered immediately without real-time transcoding delays.
