Synchronized Multimedia Output for Remote Audio and Video Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content presentation systems often limit users to either seeing or hearing the audio and video components, due to ambient noise, proximity to speakers, or lack of synchronization, especially in venues with multiple monitors displaying different content.
Innovation Solution
A computing device, such as an XR device, receives user input to identify and obtain synchronized audio, video, or other perceivable media components from nearby multimedia content sources, using techniques like gesture detection, gaze tracking, or screen interaction, and renders them locally for enhanced user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple monitors stream different content in a venue, then video content is rendered for users, but audio component cannot be heard due to ambient noise and distance from speakers
Solution Approach 1:
The system creates a copy of the audio component from the remote media player and delivers it to the user's computing device. Instead of relying on the original audio source that is affected by ambient noise and distance, the system extracts and transmits a replica of the audio signal, allowing the user to hear the audio component clearly without interference from the environment.
Solution Approach 2:
The computing device acts as an intermediary between the remote media player and the user. It receives the audio component from the media player, processes it, and delivers it to the user through the computing device's audio output, serving as a mediator that transfers the audio signal away from the harmful ambient noise environment.
2Area of stationary object
If users are distant from the media player speakers, then video can be viewed on remote displays, but audio component becomes inaudible
Solution Approach 1:
The system extracts the audio component from the remote media player and creates a separate audio stream that can be delivered to the user's computing device. This copy of the audio signal maintains its quality regardless of the user's distance from the original speakers, solving the audibility problem for distant viewers.
Solution Approach 2:
The system replaces the mechanical acoustic transmission path (sound waves traveling through air from speakers to user's ear) with an electronic signal transmission path (digital audio data transmitted from media player to computing device and converted to sound locally). This substitution allows audio to be delivered independently of physical distance.
3Illumination intensity
If only video component is rendered on remote displays, then visual content is provided, but audio component is lost
Solution Approach 1:
The system segments the multimedia content into separate video and audio components. The video component continues to be rendered on the remote media player display, while the audio component is extracted as a separate stream and delivered to the user's computing device. This segmentation allows both components to be delivered through different channels, preventing information loss.
Solution Approach 2:
The computing device serves as an intermediary that receives the audio component from the remote media player and delivers it to the user. This intermediary function ensures that the audio information that would otherwise be lost is captured and transmitted, maintaining complete multimedia content delivery.
4Reliability
If users want to access audio component from remote media player, then synchronization with video is maintained, but system complexity increases
Solution Approach 1:
The system uses feedback mechanisms to maintain synchronization between the audio component extracted from the remote media player and the video component. By continuously monitoring the timing and delivery of both components and adjusting accordingly, the system ensures that audio and video remain synchronized despite the additional complexity of extraction and transmission.
Data Source
AI summary
Various embodiments may include a method for multi-source multimedia output and synchronization in a computing device. The method may include receiving a user input selecting one of an audio component, video component, or other perceivable media component associated with multimedia content being rendered by a remote media player within in a perceptible distance of a user of the computing device. The user input indicates that the user wants the selected audio component, video component, or other perceivable media component rendered on the computing device. The method also identifies the multimedia content and obtains the identified multimedia content from a source of the multimedia content. The method also renders the selected one of the audio component, video component, or other perceivable media component from the obtained multimedia content, by the computing device, synchronized with the rendering by the remote media player within the perceptible distance of the user.
