Solution Overview

Problem

Network-based audio and video device systems face challenges in transmitting real-time indicator data without disrupting audio and video transmission or increasing network load, as existing methods are inefficient in handling dynamic and large amounts of data.

Innovation Solution

The implementation of the Indicator Data Train Protocol (IDTP) within the IEEE1722 protocol for transmitting audio and video data, which structures data into packets to efficiently transmit device indicator data by limiting measurement frequency and transmission periods, allowing for real-time data transmission without overwhelming the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If real-time indicator data is transmitted frequently to capture dynamic changes, then measurement precision is improved, but network load increases and audio/video transmission is interrupted

Engineering Contradiction:
Improveindicator data accuracyVSAvoidnetwork load
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The system dynamically adjusts the indicator transmission period based on data change characteristics. When indicator values are stable, the transmission period is extended to reduce network load. When significant changes are detected, the transmission period is shortened to maintain measurement precision. This dynamic adaptation resolves the contradiction between continuous monitoring and network load management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the transmission period parameter based on data characteristics. By modifying this temporal parameter dynamically, the system optimizes the balance between capturing real-time changes and avoiding excessive network traffic. The transmission period is adjusted from fixed to variable based on actual data behavior patterns.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If indicator data is transmitted continuously to monitor real-time changes, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvereal-time monitoring accuracyVSAvoiddata transmission system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Instead of continuous transmission, the system uses periodic transmission with variable intervals. The indicator data is transmitted at predetermined periods rather than continuously, which simplifies the transmission mechanism while still enabling real-time monitoring. The periodic action with adaptive intervals reduces system complexity compared to continuous streaming approaches.

Inventive Principle:
Principle #19Periodic action

3Productivity

If frequent indicator data transmission is implemented to capture dynamic changes, then productivity is improved, but reliability decreases due to network interruptions

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidaudio-video transmission stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts transmission frequency based on network conditions and data characteristics. When network load is high or audio-video transmission is active, the indicator transmission period is extended to maintain reliability. When network conditions permit and data changes rapidly, the period is shortened to improve productivity. This dynamic balancing act resolves the contradiction between transmission efficiency and reliability.

Inventive Principle:
Principle #15Dynamics
