HTTP Adaptive Streaming Quality Reduction in Screen Saver Mode

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing HTTP adaptive streaming technologies consume unnecessary bandwidth and resources when a multimedia stream player terminal switches to screen saver mode, as they continue to download and play video content without rendering it, leading to inefficient use of network resources and user experience degradation.

Innovation Solution

Implement a method to progressively reduce the video rendering quality of streamed digital content while maintaining audio quality when the terminal enters screen saver mode, and eventually interrupt video streaming if no user interaction occurs, using HTTP adaptive streaming technology to optimize bandwidth and resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If HTTP adaptive streaming continues to download video content in screen saver mode, then the streaming service remains ready for rapid resumption, but bandwidth and network resources are wasted unnecessarily

Engineering Contradiction:

Improvereadiness for rapid resumptionVSAvoidbandwidth consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies dynamics by making the video streaming quality adaptive based on the terminal's operational state. When screen saver mode is detected, the system dynamically adjusts the streaming quality to a lower level or interrupts the stream, and can rapidly resume at appropriate quality when the user returns. This resolves the contradiction by making the system flexible rather than static, allowing bandwidth consumption to match actual usage needs while maintaining service readiness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the streaming parameters (quality level, bitrate, resolution) based on whether the terminal is in active mode or screen saver mode. By monitoring the screen saver state and adjusting video quality parameters accordingly, the system reduces unnecessary bandwidth consumption during screen saver periods while enabling rapid resumption when the user returns, thus resolving the contradiction between resource efficiency and service readiness.

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If video streaming quality is reduced during screen saver mode, then bandwidth consumption decreases, but the resumption time may increase

Engineering Contradiction:

Improvebandwidth consumptionVSAvoidresumption time

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The patent applies preliminary action by maintaining the audio stream continuously even when video quality is reduced or interrupted during screen saver mode. The audio buffering and playback continue without interruption, so when the user returns and the screen saver mode ends, the video can resume rapidly without significant delay. This preliminary maintenance of audio streaming prepares the system for quick resumption, resolving the contradiction between bandwidth reduction and resumption speed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts video quality rather than completely interrupting the stream, allowing for flexible resumption. The adaptive nature of HTTP streaming enables the system to switch between different quality levels and resume playback quickly based on buffer status and network conditions, minimizing resumption time while still reducing bandwidth consumption during screen saver mode.

Inventive Principle:

Principle #15Dynamics

3Productivity

If the terminal maintains high quality video streaming in screen saver mode, then user experience is preserved for immediate resumption, but unnecessary network resources are consumed

Engineering Contradiction:

Improvenetwork resource efficiencyVSAvoiduser experience continuity

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by differentiating the streaming quality based on the terminal's operational context. When in screen saver mode, the system provides lower video quality or interrupts the video stream locally, while maintaining audio quality. This localized adjustment of quality matches the actual user needs during screen saver periods, improving network resource efficiency without significantly impacting user experience when the user returns, as the system can rapidly adapt to the new state.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system dynamically adapts streaming quality to match the terminal's operational state, providing high quality when active and reduced quality during screen saver mode. This dynamic adaptation ensures network resource efficiency during periods when the user is not actively viewing, while maintaining the capability to quickly restore high quality streaming when the user returns, thus balancing resource efficiency with user experience continuity.

Inventive Principle:

Principle #15Dynamics

Publication Date: 2024.07.02 ORANGE SA

AI summary

A method for managing the HTTP adaptive streaming of an item of digital content within a multimedia stream player terminal in a local communication network is disclosed, the multimedia stream player terminal being associated with a terminal for rendering the item of digital content. On detection of an active state of a screen saver mode of the rendering terminal, such a management method implements a progressive reduction of a video rendering quality of the streamed item of digital content, and maintains an audio rendering quality of the item of content.
