Digital Media Adapter Feedback Cache for Remote Audio Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing XRT protocol for remote user interface remoting in networked devices experiences significant delays due to network congestion and wireless interference, leading to sluggish or unresponsive user interfaces, particularly when providing immediate real-time feedback to user actions.
Innovation Solution
A digital media adapter (DMA) with a feedback cache is configured to store pre-configured audio clips and other feedback data, allowing for immediate playback of audio feedback without relying on continuous network communication, using protocols like XRT for command encapsulation and caching mechanisms to minimize latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time network communication is used for remote user interface feedback, then the system can provide centralized control and coordination, but network congestion and wireless interference cause significant delays making the interface appear sluggish
Solution Approach 1:
The patent pre-loads feedback audio clips and other feedback data into a local cache memory on the DMA device before they are needed. When a user action occurs, the system can immediately retrieve and play the pre-configured feedback from cache without waiting for network retrieval, thus eliminating network latency for feedback delivery while maintaining centralized control for cache management and content updates.
2Speed
If feedback data is cached locally on the DMA device, then immediate playback is possible without network delays, but additional memory resources are required
Solution Approach 1:
The patent implements a selective caching strategy where only frequently accessed or critical feedback data is stored in the local cache memory on the DMA device. Less frequently used feedback content can remain on the network server and be retrieved on-demand. This approach optimizes the balance between local storage capacity and feedback delivery speed by caching only what is necessary for immediate responsiveness.
