Video Packet Queue Spacing Under High-Throughput Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video processing systems face challenges in managing queues of video packets due to hardware limitations and storage constraints, leading to potential packet expiration and disruption in video quality and analysis.
Innovation Solution
A method for managing video packet queues by indexing packets and expiring packets based on a drop interval to maintain consistent spacing, ensuring smoother video playback and analysis by selectively removing packets that are not within the defined drop interval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video packets are queued based on hardware limitations and storage constraints, then the system can handle high-throughput video processing, but packet expiration occurs and video quality is disrupted
Solution Approach 1:
The system dynamically changes the drop interval parameter based on queue conditions. When the queue is full, instead of using a fixed drop interval, the system adjusts the interval to ensure packets are removed at appropriate rates, maintaining both throughput and quality consistency.
Solution Approach 2:
The packet removal mechanism transitions from static to dynamic by calculating drop intervals based on current queue state. The system adapts the packet removal rate dynamically, removing packets at indices that maintain consistent spacing, thereby preventing video quality disruption while managing hardware constraints.
2Quantity of substance
If packets are removed from the queue when storage is full, then storage constraints are managed, but inconsistent packet spacing causes jitter and tracking errors
Solution Approach 1:
The system calculates and adjusts the drop interval parameter dynamically based on queue fullness. By changing this parameter adaptively, the system ensures that removed packets maintain consistent spacing intervals, preventing jitter and tracking errors while managing storage capacity.
Solution Approach 2:
The system implements a feedback mechanism where the queue state (full/not full) is continuously monitored. Based on this feedback, the drop interval is adjusted to maintain consistent packet spacing. The system checks whether removing a packet at a calculated index maintains the desired spacing, and adapts accordingly.
3Device complexity
If a fixed drop interval is used for removing packets, then implementation is simple, but it does not adapt to varying processing loads and queue conditions
Solution Approach 1:
The system transforms the static fixed drop interval into a dynamic adaptive mechanism. The drop interval is recalculated based on current queue conditions and processing load, allowing the system to adapt to varying demands while maintaining reasonable implementation complexity through systematic index calculation.

AI summary
Systems and methods are disclosed for receiving a video streaming packet from a video streaming source, removing, from the queue, a queued packet based on a size of the queue achieving a threshold and based on an index assigned to the queued packet being within a drop interval from an adjacent queued packet that is not dropped from the queue, and appending the video streaming packet to the queue.
