Multimedia Data Transfer via Voice Channel Vocalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional text messaging systems in personal communication devices are limited by capacity constraints and difficulties in reading messages due to small display screens and ambient light issues, particularly problematic for users with impaired vision.
Innovation Solution
A system that vocalizes multimedia data and transmits it over a voice channel between personal communication devices, eliminating the need for a backend server and allowing for audio output on the receiving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If text messaging systems use backend servers, then message transmission is enabled, but system complexity and capacity limitations increase
Solution Approach 1:
The patent extracts the message transmission function from the backend server infrastructure and implements it directly between mobile devices using voice channel communication. This eliminates the intermediary server component while maintaining the core messaging functionality through voice-based data transmission.
Solution Approach 2:
The patent introduces voice channel communication as an intermediary mechanism to transfer multimedia data between devices. By encoding data as audible tones and transmitting through voice networks, it creates a new communication pathway that bypasses traditional server-based text messaging infrastructure.
2Productivity
If text messages are displayed on small screens, then message delivery is achieved, but readability deteriorates
Solution Approach 1:
The patent replaces the visual display mechanism with an auditory output mechanism. Instead of presenting text on a small screen, the system converts messages into audible signals that can be played through speakers or headphones, substituting the visual interface with an audio interface that is not constrained by screen size.
Solution Approach 2:
The patent changes the output parameter of message delivery from visual (text on screen) to auditory (sound waves). This parameter transformation allows the same information to be delivered in a format that is not limited by display area, thereby improving readability for users with visual impairments or in environments with poor lighting.
3Loss of information
If text messages are read on small displays, then information transmission is complete, but user comfort deteriorates in various lighting conditions
Solution Approach 1:
The patent substitutes the visual display system with an auditory output system. By converting text messages into spoken audio, the system eliminates dependency on display screens and ambient light conditions, allowing users to consume message content comfortably in any lighting environment including complete darkness.
Data Source
AI summary
In a portable multimedia device, data is passed between a sender and receiver unit by way of voice channel only. Multimedia data is vocalized and then forwarded to a receiver unit by way of the voice channel without the use of a backend server. Once received at the receiver unit, the vocalized data can be converted to an audio signal that can then output by way of an audio output device (such as a speaker, earphone, etc.).
