Solution Overview

Problem

In modern communication systems with hard-resource constraints, the separation between source coding and channel coding is not optimal, leading to challenges in maintaining high quality of service and experience due to limited mobile network resources and spatial-temporal coverage holes.

Innovation Solution

Implementing Multiple Description Coding (MDC) with machine learning and artificial intelligence to optimize the allocation and protection of source media content across different channels, utilizing the diversity of mobile communication network infrastructure, and employing techniques like carrier aggregation, beamforming, and dual-connectivity to enhance quality of service and experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Multiple Description Coding is implemented to transmit media content over different paths, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improvequality of serviceVSAvoidcoding complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The media content is segmented into multiple descriptions (first description and second description) that can be transmitted over different network paths. Each description contains sufficient information to reconstruct the content independently, ensuring reliability even if some paths fail.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple descriptions are combined at the receiver side to reconstruct the media content. The system merges the first description transmitted over the first path with the second description transmitted over the second path to achieve high-quality reconstruction.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple descriptions are transmitted over different paths, then reliability is improved, but loss of time increases due to multiple transmission paths

Engineering Contradiction:

Improvequality of serviceVSAvoidtransmission latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The media content is pre-processed into multiple descriptions before transmission, with each description optimized for independent reconstruction. This preliminary segmentation allows parallel transmission without requiring complex real-time switching or reconfiguration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically selects and activates descriptions based on real-time network conditions. If one path experiences delays or failures, the receiver can dynamically switch to using alternative descriptions without interrupting playback.

Inventive Principle:

Principle #15Dynamics
