Remote Display Update Filtering for VDI Performance

The patent extracts and removes unnecessary display updates from the transmission stream by filtering out updates that do not correspond to actual user interactions or significant display changes. This allows the system to maintain display accuracy for essential updates while reducing network bandwidth consumption by excluding redundant or unnecessary update packets.

The patent applies different quality levels to different display updates based on their importance. Critical updates (e.g., user interaction responses) are transmitted with full quality and immediacy, while less critical updates (e.g., cosmetic changes, clock updates) are filtered, consolidated, or transmitted at reduced quality. This local differentiation optimizes the balance between display accuracy and network resource consumption.

The patent implements dynamic filtering that adjusts its behavior based on real-time system conditions and update characteristics. The filter analyzes each display update's properties (such as change type, urgency, and visual significance) and dynamically determines whether to transmit it immediately, delay it, or filter it out. This dynamic approach ensures that critical updates maintain fast response times while non-critical updates are optimized for resource efficiency.

The patent employs periodic consolidation of display updates, where multiple minor updates are batched together and transmitted as a single consolidated update at appropriate intervals. This periodic action reduces the frequency of network transmissions and processor handling while maintaining acceptable display responsiveness, as the consolidated update reflects the cumulative state changes over the consolidation period.

The patent implements a feedback mechanism that continuously monitors display update characteristics and system resource usage patterns. Based on this feedback, the filtering algorithm learns which types of updates are most likely to be unnecessary and adjusts its filtering criteria accordingly. This feedback-driven approach ensures that important display information is not lost while maximizing resource utilization efficiency by targeting the filtering action at the most wasteful update types.

The patent changes key parameters of display update transmission based on update type and priority. Instead of a uniform transmit-all approach, the system modifies transmission parameters (such as transmission frequency, data granularity, and timing) according to the specific characteristics of each update. This parameter change strategy maintains information completeness for critical displays while optimizing resource efficiency for non-critical displays.
