Pre-initializing Camera Components to Reduce Video Session Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The initialization of communications sessions between devices, particularly those involving cameras, is delayed due to the processing of contact data stored remotely, which increases latency in initiating video conferences and other communication sessions.
Innovation Solution
The proposed solution involves processing audio data to determine commands and recipient information locally, sending sender information and initialization commands to the recipient device prior to sending the communication request, thereby reducing latency by pre-initializing camera components and other hardware before the communication session is initiated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If contact data is processed remotely to determine contact information, then communication requests can be properly routed, but latency increases and session initiation is delayed
Solution Approach 1:
The system performs preliminary actions by initializing camera components and processing contact data in advance before the communication session is actually initiated. When a communication request is received, the recipient device already has its camera ready and contact information prepared, eliminating the delay that would otherwise occur during session setup.
Solution Approach 2:
The patent introduces an intermediary mechanism where the communication system pre-processes contact data and maintains a cache of contact information. This intermediary cache allows devices to resolve contact information locally without always needing to query remote servers, reducing latency while maintaining accuracy through periodic updates.
2Productivity
If camera components are initialized before communication session, then session setup is faster, but device energy consumption increases
Solution Approach 1:
The system performs camera initialization in advance when communication is anticipated, but uses selective triggering based on communication patterns. The preliminary action is taken only when beneficial - such as when multiple communications are expected or when the device is already active for other reasons - thereby reducing unnecessary energy consumption while maintaining fast session setup when needed.
Solution Approach 2:
The system dynamically adjusts camera initialization behavior based on real-time conditions such as device state, communication patterns, and user activity. The camera is pre-initialized only when the device is already active or when communication patterns indicate imminent use, making the preliminary action dynamic rather than static to optimize the balance between speed and energy consumption.
3Quantity of substance
If contact data is stored remotely, then local device storage is reduced, but processing delays occur when determining contact information
Solution Approach 1:
The system implements a nested data storage structure where contact information is cached locally on devices in a simplified format, while the complete and authoritative contact data remains stored remotely on servers. This nested approach allows devices to perform fast local lookups for common contact information while maintaining the ability to retrieve complete data from remote servers when needed, thus reducing both storage requirements and resolution time.
Solution Approach 2:
The system performs preliminary actions by pre-processing and caching contact data locally on devices before it is actually needed. When contact information is required, devices can retrieve it from their local cache rather than querying remote servers in real-time, significantly reducing contact resolution time while maintaining updated contact information through periodic synchronization.

AI summary
Described are techniques for establishing video communication between devices while reducing delays associated with initialization of a camera system. When a command from a sender device to initiate a communications session with a recipient device is received, the command may include recipient information indicative of the recipient device. Correspondence between the recipient information and sender contact data may be used determine a recipient profile identifier. Prior to providing a communication request to the recipient device, an initialization command may be provided to the recipient device to cause the recipient device to begin initializing a camera system. Providing the initialization command to the recipient device responsive to the command from the sender device, in advance of the communication request, enables the communications session to be initiated more rapidly than if the recipient device began to initialize the camera system responsive to the communication request.
