Audio Visual Device On Screen Display Content Flow Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio/video (A/V) devices are difficult for users to navigate as they do not provide a clear visualization of operations, making it hard for users to understand how content is processed and what operations are required, especially when handling multiple sources and destinations.
Innovation Solution
The implementation of an on-screen display (OSD) processing unit and control unit in A/V devices to create a user interface that visualizes the flow of content through icons and connection diagrams, indicating operational states and functions of modules, allowing users to easily recognize operations and changes in content flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional A/V devices are used without visualization interface, then device complexity is reduced, but ease of operation deteriorates as users cannot understand operations
Solution Approach 1:
The patent introduces an OSD processing unit as an intermediary between the complex internal operations of A/V devices and the user. This unit generates visual representations (icons, connection diagrams, content flow) that mediate the user's understanding of device operations without requiring changes to the core device architecture
Solution Approach 2:
The patent creates visual copies or representations of the actual device operations and content flow. Instead of showing real-time internal states, it generates simplified graphical copies (icons representing modules, lines representing connections) that mirror the operational state in an understandable format
2Adaptability or versatility
If A/V devices handle multiple sources and destinations, then adaptability is improved, but ease of operation deteriorates due to difficulty in recognizing operations
Solution Approach 1:
The patent segments the complex content flow into discrete visual elements: individual icons represent specific modules (sources, destinations, processing units), and separate lines represent different content paths. This segmentation allows users to understand each component's role independently while grasping the overall system behavior
Solution Approach 2:
The patent utilizes visual differentiation (including color coding in the display) to distinguish between different content flows, operational states, and module types. This visual encoding enables users to quickly identify and track multiple simultaneous operations without confusion
3Loss of information
If internal operations are not revealed to users, then device complexity is simplified, but loss of information increases as users cannot understand processing
Solution Approach 1:
The OSD processing unit acts as an information intermediary that extracts, transforms, and presents relevant operational information to users. It mediates between the complex internal processing and user comprehension needs, providing just enough information to understand operations without exposing unnecessary technical complexity
Solution Approach 2:
The patent provides localized information about specific modules and their operational states through the visual interface. Each icon and connection line provides locally relevant information about that particular component's role and state, allowing users to understand the system in manageable local contexts rather than overwhelming global complexity
Data Source
AI summary
An audio/video (A/V) device and a method of controlling the operation thereof, which visualize operation states in or among A/V devices into a flow of content. The A/V device includes an on screen display (OSD) processing unit to OSD process information, and a control unit to control the OSD processing unit so that the OSD processing unit OSD processes a plurality of modules constituting the A/V device and functions thereof. Accordingly, it is possible for a user to easily recognize operations in and among the A/V devices, which provides convenient operation to the user.
