Event-Based Image Recording for Bandwidth and Power Efficiency

Solution Overview

Problem

Streaming devices face bandwidth and power consumption issues, leading to inefficiencies and potential missed security events due to continuous recording and streaming, especially in environments with multiple devices.

Innovation Solution

Implementing dynamic formulas that adjust device operation based on location, purpose, and power type, using parameters like padding, inactivity threshold, and maximum event length to optimize recording and streaming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous recording and streaming is implemented, then security events are captured reliably, but bandwidth consumption increases significantly

Engineering Contradiction:

Improvesecurity event capture reliabilityVSAvoidbandwidth consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent segments continuous video recording into discrete event-based clips. Instead of streaming all captured footage, the system identifies and extracts only relevant event segments (e.g., detected objects, motions, or anomalies) for transmission. This segmentation reduces bandwidth consumption while maintaining reliability for capturing important security events.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements periodic detection and evaluation cycles to determine when events occur. Rather than continuous streaming, the device periodically analyzes captured footage for event conditions and only streams clips when events are detected. This periodic action pattern significantly reduces bandwidth usage while ensuring security events are captured and transmitted reliably.

Inventive Principle:

Principle #19Periodic action

3Loss of energy

If targeted recording approaches are implemented to save bandwidth and power, then efficiency improves, but device functionality is reduced

Engineering Contradiction:

Improvebandwidth and power efficiencyVSAvoiddevice functionality

Core Design Contradiction:

Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic event recording profiles that adapt to different device types, locations, and purposes. The system dynamically adjusts recording parameters (such as clip length, detection sensitivity, and streaming frequency) based on device characteristics and environmental context. This dynamic adaptation maintains comprehensive device functionality while optimizing bandwidth and power efficiency for each specific use case.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes key recording and streaming parameters based on device type, location, and purpose. For example, security cameras in high-risk areas may use different detection thresholds and clip lengths compared to monitoring devices in low-risk areas. These parameter changes allow the system to maintain full functionality where needed while achieving efficiency gains in other contexts.

AI summary

An electronic device comprises an image sensor, one or more processors, and memory storing instructions for receiving an event recording profile based on configuration data of the electronic device, the configuration data including a location type or a power type; receiving a plurality of images of a scene captured by the image sensor; detecting a trigger event based on one or more of the plurality of images of the scene; in response to detecting the trigger event, identifying an object of interest in one or more of the plurality of images of the scene; creating an event clip from the stored images that include the object of interest, wherein creating the event clip includes configuring a clip length based on the event recording profile; and providing the event clip for display.
