Media Stream Segmentation for Adaptive Channel Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting media data streams fail to efficiently accommodate devices with varying functionalities, leading to increased power consumption and complexity in processing, as they require all transmission channels to be continuously received and processed, regardless of device capabilities.
Innovation Solution
The method generates a first data stream in basic quality and additional data streams in improved quality, which are assigned to specific transmission channels based on device capabilities, allowing only necessary channels to be processed, reducing power consumption and complexity by using compression and adaptive data rates aligned with bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all transmission channels are continuously received and processed, then complete media quality is achieved, but power consumption increases and device complexity increases
Solution Approach 1:
The media data stream is segmented into multiple independent data streams with different quality levels (first data stream in basic quality, second data streams in improved quality). Each data stream is transmitted through separate transmission channels, allowing the receiving device to selectively receive only the necessary segments based on its capabilities, thus avoiding continuous processing of all channels and reducing power consumption.
Solution Approach 2:
The receiving device performs partial action by receiving and processing only the first data stream in basic quality when operating in power-saving mode, rather than receiving all data streams for complete quality. This partial reception satisfies basic functionality while significantly reducing power consumption and processing complexity.
2Reliability
If all transmission channels are continuously received and processed, then complete media quality is achieved, but device complexity increases
Solution Approach 1:
The data stream is divided into segmented components (first data stream and second data streams) with clearly defined quality levels. The receiving device can selectively process only the necessary segments based on its processing capabilities, reducing the overall processing complexity while maintaining acceptable media quality.
Solution Approach 2:
The device performs partial processing by handling only the first data stream in basic quality when in power-saving mode, avoiding the complexity of processing all second data streams for improved quality. This reduces computational complexity and processing requirements while still providing functional media playback.
3Productivity
If data is compressed using compression methods, then transmission efficiency is improved, but data processing complexity increases
Solution Approach 1:
The patent applies parameter changes by using standardized compression methods with predefined quality parameters. The first data stream is compressed to basic quality and second data streams are compressed to improved quality levels. This standardization allows efficient transmission while managing processing complexity through established compression algorithms and quality parameters.
4Productivity
If data rate is adapted to transmission channel bandwidth, then transmission efficiency is improved, but encoding complexity increases
Solution Approach 1:
The encoding process is segmented into multiple passes or stages, where the first data stream is encoded at a data rate adapted to basic bandwidth requirements, and second data streams are encoded at higher data rates for improved quality. This segmentation allows efficient transmission across different bandwidth conditions while managing encoding complexity through hierarchical quality levels.
