Mobile Device Media Streaming Power Reduction via Block Download
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media streaming on mobile devices leads to high power consumption due to continuous operation of the receiver unit, affecting battery life during dynamic adaptive streaming.
Innovation Solution
A method for mobile devices to download media streams in blocks, determining the required playback time based on a minimum playback time to create sufficient gaps for the receiver unit to switch to an idle mode, reducing active time and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver unit operates continuously to download media segments in dynamic adaptive streaming, then seamless playback and adaptation to network conditions is achieved, but power consumption increases and battery lifetime decreases
Solution Approach 1:
The invention segments the media stream into blocks of data segments, where each block corresponds to a specific playback time interval. This segmentation allows the receiver unit to download entire blocks in advance and then enter idle mode, breaking the continuous operation pattern while maintaining playback reliability through pre-loaded buffer content.
Solution Approach 2:
The invention implements preliminary action by determining and downloading blocks of data segments before they are needed for playback. The system calculates the required playback time based on minimum playback time parameters and downloads corresponding blocks in advance, allowing the receiver unit to remain in idle mode during playback periods without interrupting the streaming experience.
2Productivity
If the receiver unit operates continuously to maintain active state for media streaming, then data segments can be downloaded and played back without interruption, but the active time increases reducing battery lifetime
Solution Approach 1:
The invention implements periodic action by establishing regular cycles of downloading and playback. The system determines required playback time based on minimum playback time parameters and creates periodic download intervals followed by idle periods. This periodic operation pattern allows the receiver unit to alternate between active downloading and idle states, reducing overall active time while maintaining streaming productivity through buffered content.

AI summary
The present invention relates to a method (20) for operating a mobile device (10). The mobile device (10) is configured to download a media stream comprising a plurality of data segments (S1-Sn) and to playback the media stream during download. The media stream is downloaded as a plurality of blocks of data segments and each block of data segments comprises a set of the plurality of data segments (S1-Sn) representing a corresponding media stream portion of the media stream. According to the method, a required playback time (T) for a next block of data segments to be downloaded is determined depending on a predetermined required minimum playback time (C) which defines a required minimum time duration for playing back the media stream portion provided by the next block of data segments.
