AVC Processor Independent Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require the computer unit to be operational for media and voice playing functions, limiting independent use of media and voice playing units when the computer unit is powered off, in sleep, standby, or malfunctioning.
Innovation Solution
An audio, video, and voice communication (AVC) processor that allows independent operation of media and voice playing units by receiving external AV signals and voice transceivers, enabling wireless speaker, display, or hands-free speakerphone functionality regardless of the computer unit's operational state through control signals and I/O ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the computer unit is required to be operational for media and voice playing functions, then the system can perform general computing functions, but the media and voice playing units cannot be used independently when the computer unit is powered off, in sleep, standby, or malfunctioning
Solution Approach 1:
The system is divided into two independent operational paths: one through the computer unit for general computing functions, and another through the AVC processor for media and voice playing functions. This segmentation allows the media and voice playing units to operate independently when the computer unit is non-operational, while maintaining the ability to perform general computing functions when needed.
Solution Approach 2:
The AVC processor acts as an intermediary component that receives control signals from the control unit and routes them to the media and voice playing units. This intermediary enables the system to bypass the computer unit when it is non-operational, allowing independent use of media and voice playing functions while preserving the overall system architecture.
2Ease of operation
If the computer unit must be operational to access media and voice playing functions, then system resources are consolidated, but user convenience is reduced when the computer unit is powered off or malfunctioning
Solution Approach 1:
The system implements local quality by providing different operational modes: full system operation when the computer unit is functional, and limited media/voice playback operation when only the AVC processor is operational. This allows the system to adapt its functionality to the current operational state, improving user convenience without compromising overall system reliability.
Solution Approach 2:
The control unit is configured in advance to detect whether the computer unit is operational and to automatically switch between operational modes. This preliminary detection and automatic switching mechanism improves user convenience by eliminating the need for manual configuration while maintaining system reliability through pre-planned fallback paths.

AI summary
In an example, an audio, video, and voice communication (AVC) processor includes an audio and video (AV) port to receive audio and video (AV) signals and an audio and voice input/output (I/O) port to communicate with a voice transceiver. The control unit, coupled to the AVC processor, controls the AVC processor to select the received signals and enables the AVC processor to transmit the selected signals to a media and voice playing unit.
