Solution Overview

Problem

Existing Rich Media Service technologies face challenges in adapting multimedia content for terminals with varying screen sizes and resources, leading to difficulties in composing scenes that are excessively complex for smaller screens.

Innovation Solution

A user interface method and apparatus for Rich Media Service terminals that check the header of received streams for adaptation information, filtering and composing adaptive scenes based on terminal-specific conditions and performance, ensuring optimal resource utilization and display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the same Rich Media service is provided to multiple terminals having different characteristics, then service coverage is improved, but scene composition complexity increases for small-screen terminals

Engineering Contradiction:

Improveservice coverageVSAvoidscene composition complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adapts scene composition based on terminal characteristics. The renderer checks adaptation information in the header and dynamically composes scenes appropriate for the terminal's screen size and capabilities, transforming a static scene composition approach into a dynamic one that adjusts to different terminals.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different scene composition strategies are applied to different terminals based on their specific characteristics. Small-screen terminals receive simplified scenes while large-screen terminals receive comprehensive scenes, allowing each terminal to process only the complexity level appropriate for its capabilities.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If a terminal with a small screen receives a scene optimized for a large screen size, then service compatibility is improved, but resource utilization deteriorates

Engineering Contradiction:

Improveservice compatibilityVSAvoidresource utilization

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by providing only the necessary scene composition elements for each terminal type. Small-screen terminals receive filtered scenes with only the essential elements needed for their display capabilities, avoiding the excessive processing of unnecessary scene data that would waste resources.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Adaptation information is prepared in advance in the header of the broadcast stream, allowing terminals to pre-determine their resource allocation needs before actual scene rendering. This preliminary preparation enables efficient resource management by knowing in advance what level of processing is required.

Inventive Principle:

Principle #10Preliminary action

AI summary

A user interface method and apparatus for a Rich Media service in a terminal. A decoder decodes a received stream to check a header of the received stream. A renderer adaptively composes a scene using scene composition elements of the received stream, according to adaptation information in the header checked by the decoder, and a display displays the adaptively composed scene.
