Solution Overview

Problem

Existing video-audio systems cannot simultaneously display different and irrelevant image frames for multiple users while allowing each user to hear the corresponding sound effects.

Innovation Solution

A video-audio playing system comprising a display unit, a processing unit, and a sound playing unit that simultaneously or time-divisionally displays independent image frames and captures sound signals, enabling each user to watch different image frames through corresponding glasses and hear the respective sound effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single display is used to display different channels for multiple users, then different viewers can watch different image frames simultaneously, but users cannot hear sound effects of their respective watched image frames

Engineering Contradiction:

Improvedisplay capability for multiple usersVSAvoidaudio-visual synchronization for each user

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system divides the audio output into separate channels corresponding to each image frame. The processing unit captures sound signals from each image frame separately, and the sound playing unit plays different sound signals through different audio channels (e.g., left/right earphones, different speakers), allowing each user to hear only the audio corresponding to their watched content

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different audio qualities and types are provided to different users based on their specific viewing needs. Each user receives customized audio output matched to their selected image frame, with the ability to adjust volume and audio characteristics independently for each channel

Inventive Principle:

Principle #3Local quality

2Quantity of substance

If multiple sound signals are played through the same audio channel, then all users can hear all sound effects, but users cannot hear sound effects of their respective watched image frames independently

Engineering Contradiction:

Improvenumber of sound signalsVSAvoidaudio content interference

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The audio output is segmented into multiple independent channels, with each channel dedicated to a specific image frame. The sound playing unit is configured to output different sound signals through different audio channels, preventing audio content interference between users

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The processing unit acts as an intermediary that captures and processes sound signals from each image frame separately before transmitting them to the sound playing unit. This intermediary processing ensures that each audio channel receives only the relevant sound signals for its corresponding image frame

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A video-audio playing system relating to 2-view application and a method thereof are provided. In the present invention, sound signals respectively corresponding to two independent image frames are captured and played in coordinating with the displaying of these two independent image frames. Accordingly, two users can respectively watch two image frames which are different and irrelevant each other in the same display, and further respectively hear sound effects of the respective image frames at the same time.
