Predictive Light Command Transmission for Zigbee Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies, such as ZigBee, often result in lost or corrupted light commands during transmission, leading to non-smooth light effects due to their unreliable nature and limited bandwidth, especially when synchronized with time-sensitive content.
Innovation Solution
An electronic device and method that predict and transmit alternative light commands, which specify a portion of the light effect for multiple periods, to ensure smooth rendering even if original light commands are lost, by determining the likelihood of command arrival and using historical trajectories to extrapolate the light effect's trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light commands are transmitted over Zigbee network, then existing smart home lighting products can be used, but light commands may be lost or corrupted leading to non-smooth light effects
Solution Approach 1:
The transmitter determines a second part of the light effect in advance before transmitting the light command. This predictive approach allows the receiver to reconstruct lost light effects using pre-determined information, resolving the contradiction by ensuring reliability through preliminary preparation while maintaining compatibility with existing Zigbee infrastructure
Solution Approach 2:
The system transmits alternative light commands that can compensate for potential command losses. By preparing alternative commands in advance that specify light effect portions for multiple periods, the system cushions against the unreliable nature of Zigbee transmission while maintaining smooth light effects
2Loss of time
If light commands are transmitted with pre-agreed duration, then synchronization with content is achieved, but there is insufficient time to retransmit lost commands
Solution Approach 1:
The transmitter determines the second part of the light effect in advance during the first period, allowing the receiver to use this pre-determined information to reconstruct lost light effects without requiring additional retransmission time. This resolves the timing constraint while maintaining reliability
3Reliability
If alternative light commands are transmitted for multiple periods, then smooth light effects are ensured, but network bandwidth consumption increases
Solution Approach 1:
The alternative light command specifies a portion of the light effect for multiple periods by copying and extending the light effect specification beyond the original single-period command. This approach ensures smooth rendering across multiple periods while using the same data structure and format, minimizing bandwidth overhead compared to transmitting separate commands for each period

AI summary
An electronic device is configured to determine apart (161) of a light effect for a first period and determine a succeeding part (186) of the light effect for a second period succeeding the first period. The electronic device is further configured to determine a likelihood that a second original light command specifying a part (162) of a light effect for the second period will not arrive at its destination and transmit an original first light command or determine and transmit an alternative first light command in dependence on the likelihood and/or the determined succeeding part of the light effect. The original first light command specifies the part of the light effect and the alternative first light command is determined based on the part and the succeeding part of the light effect and specifies a portion of the light effect for both the first period and the second period.
