Solution Overview

Problem

Existing multimedia content redirection methods face challenges in ensuring immediate compatibility and efficient reproduction between mobile terminals and multimedia players in ad-hoc networks, often requiring complex configurations and failing to provide high-level reproduction functions.

Innovation Solution

A multimedia content redirection method that dynamically extends the functions of a sink node by transmitting a mobile code, allowing seamless redirection of multimedia content from a source node to a nearby sink node, enabling enhanced media reproduction performance without complex installations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multimedia content is redirected to a sink node in an ad-hoc network, then reproduction performance is enhanced, but compatibility between mobile terminal and multimedia player cannot be ensured

Engineering Contradiction:
Improvereproduction performanceVSAvoidcompatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameters of the sink node dynamically by injecting mobile code during runtime. This allows the sink node to adapt its reproduction capabilities to match the source node's requirements, resolving the compatibility issue while maintaining enhanced reproduction performance through code-based parameter adjustment rather than hardware modification.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The mobile code mechanism enables the sink node to perform multiple functions by dynamically loading different code modules. This universal approach allows a single sink node to handle various multimedia formats and protocols, ensuring compatibility across different mobile terminals while maintaining high reproduction performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If compatibility is provided between mobile terminal and multimedia player, then content redirection becomes possible, but configuration becomes complicated

Engineering Contradiction:
ImprovecompatibilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements self-service through automatic mobile code injection and execution. The sink node automatically configures itself by receiving and executing mobile code from the source node, eliminating the need for manual user configuration while ensuring compatibility. This self-configuration mechanism resolves the contradiction between providing compatibility and maintaining simple operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mobile code is prepared and injected in advance during the connection establishment phase, before actual multimedia playback begins. This preliminary configuration action ensures compatibility is established beforehand, avoiding the need for complex runtime configuration by the user.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If existing multimedia player is used to connect mobile phone to external devices, then connection is simple, but high-level reproduction functions cannot be provided

Engineering Contradiction:
Improveconnection simplicityVSAvoidreproduction functions
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the reproduction system into two parts: the simple connection layer (handled by existing multimedia player) and the enhanced function layer (provided by mobile code injection). This segmentation allows the system to maintain simple connection operations while adding high-level reproduction functions through separate, dynamically loaded code modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges the existing multimedia player's connection capabilities with the enhanced reproduction functions of the mobile code. This combination allows the system to retain the simplicity of existing players while augmenting them with advanced reproduction capabilities through code-based function extension.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A multimedia content redirection method is provided. The multimedia content redirection method reproduces media content at a sink node employing enhanced media reproduction performance by redirecting a current media content being reproduced to the sink node when the sink node, such as audio device or media player, capable of reproducing multimedia contents is discovered in a network while a source node such as mobile terminal is reproducing the media content in an ad-hoc network.
