Adaptive Codec Configuration for Dynamic Bandwidth Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face challenges in transmitting encoded data efficiently over varying network bandwidths, as existing technologies often prioritize networks based on predetermined settings rather than adapting to actual available bandwidth, leading to suboptimal data transmission quality.
Innovation Solution
Implementing a system that dynamically selects a communication network, estimates available bandwidth, and configures codecs accordingly to match the available bandwidth, ensuring optimal data transmission by using a method that includes a network detection module, bandwidth estimation module, and codec configurator to adaptively encode and transmit data.

1Productivity
If a voice codec is configured to transmit at a predetermined rate for WIFI network, then the encoding is optimized for WIFI bandwidth, but the codec cannot utilize the full bandwidth available in various WIFI networks
Solution Approach 1:
The system dynamically adjusts codec configuration parameters based on real-time network bandwidth conditions. The codec transitions from static predetermined rates to dynamic rate adaptation, allowing it to optimize transmission quality for each specific network condition while maintaining compatibility across different network types.
Solution Approach 2:
The invention changes the operational parameters of the codec (bitrate, encoding quality, frame size) based on measured network bandwidth. By monitoring available bandwidth and adjusting codec parameters accordingly, the system maximizes data transmission efficiency while maintaining adaptability across varying network conditions.
2Manufacturing precision
If applications are configured to transmit data at predetermined rates for specific network types, then the encoding is optimized for that network type, but the quality or fidelity decreases when bandwidth is lower than expected
Solution Approach 1:
The system implements feedback mechanisms where the actual network bandwidth is measured and used to adjust codec configuration in real-time. This closed-loop approach ensures that encoding quality is optimized for the actual available bandwidth, preventing quality degradation that would occur with fixed predetermined rates.
Solution Approach 2:
The system performs preliminary bandwidth estimation and codec configuration selection before actual data transmission begins. By pre-configuring the codec based on estimated network conditions, the system prepares the optimal encoding parameters in advance, ensuring maintained fidelity even when network conditions vary during transmission.
