Solution Overview

Problem

In systems with limited bandwidth, concurrent transmission of I frames from multiple video channels leads to insufficient bandwidth, limiting the number of channels that can be transmitted and causing non-fluency in video playback.

Innovation Solution

A method for data transmission that involves generating a new transmission moment for key data based on a preset interval to avoid collisions between data from newly and previously accessed data sources, ensuring the interval between these moments is greater than or equal to the preset interval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple video channels transmit I frames concurrently to improve video fluency, then video playback quality is improved, but transmission bandwidth becomes insufficient

Engineering Contradiction:
Improvevideo playback fluencyVSAvoidtransmission bandwidth
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements periodic transmission of I frames by calculating and assigning specific transmission moments to different video channels. The receiving end determines transmission intervals based on channel characteristics and bandwidth conditions, forcing concurrent channels to transmit at different periodic intervals rather than simultaneously, thus resolving the bandwidth conflict while maintaining video fluency.

Inventive Principle:
Principle #19Periodic action

2Productivity

If the number of video channels is increased to utilize available bandwidth, then channel capacity is improved, but time conflicts between I frame transmissions occur

Engineering Contradiction:
Improvechannel capacityVSAvoidtransmission time conflict
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The receiving end performs preliminary calculation of transmission moments for each video channel before actual transmission occurs. By pre-determining the optimal transmission time for each channel's I frames based on channel capacity and historical transmission data, the system avoids time conflicts proactively, allowing more channels to be accommodated without transmission collisions.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If I frames are transmitted with larger bandwidth requirements to ensure complete picture information, then picture quality is improved, but the number of transmissible channels is limited

Engineering Contradiction:
Improvepicture completenessVSAvoidnumber of channels
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent dynamically adjusts transmission parameters including bandwidth allocation and transmission timing for each video channel. By changing the transmission moment parameter and adapting bandwidth usage based on channel conditions, the system maintains complete picture information in each I frame while optimizing the total number of channels that can be transmitted simultaneously within available bandwidth constraints.

Inventive Principle:
Principle #35Parameter changes
