Video Decoding Load Balancing Across Hardware and Software Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video surveillance systems, there is a need for efficient load balancing between hardware and software decoding resources to handle multiple video streams dynamically, as the number of streams being decoded constantly changes.
Innovation Solution
A load balancing method that distributes new decoding processes among hardware and software resources, prioritizing hardware resources, by monitoring device loads, selecting suitable hardware devices, and dynamically reallocating decoding processes to balance loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video decoding is carried out by software running on the CPU, then the system can handle decoding without additional hardware, but the decoding efficiency is insufficient and cannot handle multiple streams simultaneously
Solution Approach 1:
The system segments the video decoding task by dividing it into multiple independent decoding processes that can be distributed across multiple hardware devices. Each hardware device handles a portion of the total decoding load, enabling parallel processing of multiple video streams simultaneously while maintaining software-based task management and distribution.
2Productivity
If multiple hardware devices are provided for video decoding, then the number of streams that can be decoded increases, but the complexity of allocating and balancing loads between devices increases
Solution Approach 1:
The system implements self-service load balancing where the load balancing logic automatically monitors the load status of each hardware device and dynamically allocates new decoding processes to appropriate devices. The system autonomously adjusts the distribution of decoding tasks based on real-time device availability and current load conditions without requiring manual intervention, thereby managing multiple hardware devices efficiently.
3Quantity of substance
If the number of decoding streams is increased, then the system can handle more video surveillance feeds, but the load on hardware devices becomes unbalanced and some devices become overloaded
Solution Approach 1:
The system implements feedback-based load balancing by continuously monitoring the load status of each hardware device and using this information to make dynamic allocation decisions. When the number of decoding streams increases, the load balancing logic receives feedback about device load levels and automatically redistributes new decoding processes to maintain balanced loads across all devices, preventing any single device from becoming overloaded.

AI summary
A load balancing method for video decoding. The load balancing includes first determining which hardware devices are suitable for the new decoding process, and determining the current load of each of the suitable hardware devices. From the suitable devices potential devices are selected having a current load less than a threshold and overloaded devices are selected having a load greater than or equal to the threshold. If there are no suitable devices, then the decoding process is implemented by software decoding. If the list of potential hardware devices includes only one potential hardware device, then the decoding process is implemented on the hardware device. If the list of potential hardware devices includes more than one potential hardware device, then it is determined how many decoding processes are currently running on each potential hardware device, and the new decoding process is implemented on the potential hardware device having the fewest processes.
