Engineering Contradiction Analysis
1Quantity of substance
If bandwidth is allocated to multiple sink devices in a point-to-multipoint Bluetooth network, then the quantity of connected devices increases, but bandwidth over-utilization occurs leading to connection instability
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the source device continuously monitors connection qualities and adjusts configuration parameters (codec type, bitrate, sampling rate) for each sink device in real-time. This dynamic adaptation allows the system to maintain stable connections across multiple devices by responding to changing network conditions rather than using static bandwidth allocation.
Solution Approach 2:
The patent applies different configuration parameters to different sink devices based on their individual connection qualities. Each sink device receives customized audio parameters (codec selection, bitrate, sampling rate) tailored to its specific connection conditions, allowing optimal performance for each device while managing overall network bandwidth effectively.
2Manufacturing precision
If configuration parameters are adjusted for one sink device, then playback quality for that device improves, but bandwidth availability for other sink devices decreases
Solution Approach 1:
The patent changes multiple configuration parameters (codec type, bitrate, sampling rate, channel configuration) to achieve different quality levels for different sink devices. By selecting from multiple parameter combinations, the system can optimize playback quality for each device according to its connection capabilities while ensuring total bandwidth consumption remains within available network capacity.
Solution Approach 2:
The patent allocates bandwidth partially to each sink device based on its needs and connection quality, rather than providing equal or maximum bandwidth to all devices. This partial allocation ensures that high-quality playback for one device does not completely consume available bandwidth, leaving sufficient resources for other devices in the network.
3Manufacturing precision
If high bitrate is used for audio transmission, then playback quality improves, but bandwidth consumption increases causing connection instability in multi-device networks
Solution Approach 1:
The patent dynamically changes the bitrate parameter based on connection quality for each sink device. When connection conditions are excellent, higher bitrates are used to maximize audio quality. When connection quality degrades or multiple devices are connected, the system automatically reduces bitrate to maintain stable connections, thus adapting audio quality to available bandwidth conditions.
Solution Approach 2:
Different bitrate levels are applied to different sink devices according to their specific connection qualities. Devices with superior connection stability receive higher bitrates for better audio quality, while devices with weaker or more variable connections receive lower bitrates to ensure stable playback without buffer underruns or audio drops.

AI summary
Various arrangements for managing a plurality of multimedia communication links in a point-to-multipoint Bluetooth network established between a source device and a plurality of sink devices are presented. An initial set of values of configuration parameters respectively related to each sink device of the plurality of sink devices can be determined. An initial value of a maximum bandwidth usage parameter related to the point-to-multipoint Bluetooth network can be determined. A new set of values of the configuration parameters different from the initial set of values can be determined. The new set of values may be determined to allocate bandwidth usage values between the plurality of multimedia communication links without exceeding the value of the maximum bandwidth usage parameter.
