Solution Overview

Problem

Current multimedia network systems continue to transmit audio and video streams even when their output is blocked by user interface actions, leading to unnecessary network load and bandwidth waste.

Innovation Solution

A method where a computing device detects user interface actions blocking audio or video output and sends a request to the server to stop transmission of the corresponding stream portion, reducing network load by filtering out the blocked content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the server continues to transmit audio and video streams even when output is blocked, then the transmission reliability is maintained, but network bandwidth is wasted and network load increases

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidnetwork bandwidth waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system implements feedback by monitoring user interface actions (such as window covering or muting) and automatically sending notifications to the server to adjust data stream transmission. This feedback loop ensures that transmission is dynamically adapted to actual playback needs, maintaining reliability when needed while avoiding bandwidth waste when output is blocked.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The computing device autonomously detects when its own output is blocked through user interface actions and self-manages the transmission optimization by notifying the server. This self-service mechanism eliminates the need for continuous server-side monitoring while ensuring both reliability and bandwidth efficiency.

Inventive Principle:
Principle #25Self-service

2Loss of information

If the server transmits complete multimedia data streams, then the content completeness is ensured, but network load and CPU cycles are unnecessarily consumed

Engineering Contradiction:
Improvecontent completenessVSAvoidnetwork usage efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The multimedia data stream is segmented into separate audio and video components, allowing the server to selectively transmit only the unblocked portions. This segmentation enables partial transmission optimization where blocked content (e.g., video when covered, audio when muted) is excluded while maintaining completeness of transmitted content.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically changes transmission parameters based on playback state by notifying the server to adjust which data stream portions are transmitted. When output is blocked, the transmission parameters are modified to exclude the blocked content type, improving network usage efficiency while ensuring completeness of actually played content.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If the computing device processes complete multimedia streams, then the output quality is maintained, but CPU cycles are wasted on processing blocked content

Engineering Contradiction:
Improveoutput qualityVSAvoidCPU cycle consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary detection of blocked output through user interface actions before the blocked content is fully processed. By identifying the blockage early and notifying the server to stop transmission of the blocked stream portion, the device avoids wasting CPU cycles on processing content that will not be output, while maintaining quality of unblocked content.

Inventive Principle:
Principle #10Preliminary action

AI summary

A multimedia data stream including an audio data stream and a video data stream is received from a server at a computing device. An audio output signal for the audio data stream and a video output signal for the video data stream are generated. A user interface action that blocks output of one of the audio data stream and the video data stream is detected via the computing device. A multimedia traffic reduction request is sent to the server instructing the server to stop transmission of a portion of the multimedia data stream associated with the blocked output of one of the audio data stream and the video data stream.
