Handheld Media Transfer Protocol for Audio-Visual Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio/visual systems lack the ability to wirelessly transfer media files and media descriptive data between handheld electronic devices and audio/visual systems, and do not allow for remote control of the audio/visual system from the handheld device, making it inconvenient to manage and play media content across both devices.
Innovation Solution
The system enables wireless transfer of media files and media descriptive data between handheld electronic devices and audio/visual systems using BLUETOOTH technology, allowing for real-time streaming and control of the audio/visual system through a new protocol layer that includes metadata communication for seamless media management and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media files are transferred wirelessly between handheld devices and audio/visual systems, then media management convenience is improved, but system complexity increases due to protocol integration requirements
Solution Approach 1:
The patent introduces a protocol translation layer that acts as an intermediary between BLUETOOTH communication and audio/visual system control protocols. This intermediary component translates messages between different protocol formats, enabling seamless media file transfer and control without requiring complex direct integration between devices. The protocol layer handles format conversion and command translation, reducing the complexity burden on individual devices while maintaining ease of operation.
2Ease of operation
If remote control functionality is added to handheld devices, then user accessibility is improved, but device functionality complexity increases
Solution Approach 1:
The handheld device is designed with universal control capabilities that can manage multiple audio/visual system functions through a single integrated interface. The device combines media file transfer, playback control, and system configuration capabilities in one unit, allowing users to control various functions (play, pause, skip, volume, etc.) without needing separate control devices. This multi-functionality approach improves accessibility while consolidating complexity into a unified control architecture.
3Speed
If real-time media streaming is implemented, then media playback responsiveness is improved, but data transmission requirements increase
Solution Approach 1:
The system performs preliminary actions by establishing BLUETOOTH connections and preparing media transfer protocols before actual playback begins. Media files are pre-loaded or pre-positioned in the audio/visual system memory before playback is requested, allowing real-time streaming without continuous high-volume data transmission during playback. This preliminary preparation reduces the data transmission burden during actual playback while maintaining responsive performance.
