Audio Routing for Video Capture Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of adding audio to video after recording is time-consuming and laborious, requiring additional editing and formatting, and users face challenges in gauging remaining audio content, which affects the timing of video capture.
Innovation Solution
A method and system that allow audio routing during video capture, enabling users to select and mix audio from multiple sources in real-time, with features like an audio progress bar for better timing control, and encoding audio with video for simultaneous recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is added to video after recording through post-editing, then audio content can be incorporated into the video, but the process becomes time-consuming and laborious requiring additional editing software and resources
Solution Approach 1:
The patent applies preliminary action by routing audio signals from audio playback applications to the video capture application before the video recording is completed. The audio signal is prepared and transmitted in advance through the audio routing mechanism, allowing the audio and video to be synchronized during the recording process itself, eliminating the need for subsequent post-editing operations.
Solution Approach 2:
The patent merges the audio capture and video capture operations into a single integrated recording process. By combining the audio signal routing with the video capture functionality, the system enables simultaneous recording of both audio and video streams, eliminating the separate post-editing step and reducing overall production time.
2Adaptability or versatility
If traditional post-recording editing is used, then audio and video can be combined, but additional editing software and resources are required increasing costs
Solution Approach 1:
The patent implements multi-functionality by enabling the video capture application to perform both video recording and audio signal routing functions. The system allows a single application to handle multiple tasks - capturing video, receiving audio signals from various audio playback applications, mixing audio streams, and encoding both audio and video together - thereby eliminating the need for separate dedicated editing software.
Solution Approach 2:
The patent combines multiple functions into the video capture application, including audio signal routing, audio mixing, and video encoding. This integration consolidates what would traditionally require separate editing software and hardware resources into a single unified system, reducing overall device complexity and production costs.
3Ease of operation
If audio content duration is not displayed, then users can record without timing constraints, but users cannot gauge remaining audio content and appropriately time the ending of video
Solution Approach 1:
The patent implements feedback by displaying the duration of available audio content to the user during the recording process. This information feedback allows users to see how much audio time remains and adjust their video recording duration accordingly, ensuring proper synchronization between audio and video without compromising recording flexibility.

AI summary
Systems and methods for routing audio for audio-video recordings allow a user to record desired audio with captured video at the time the video is being captured. Audio from one or more sources may be routed to the video capture application and recorded with the video. In one or more examples, audio may be routed from another application, e.g., an audio playback application, running on the same device as the video capture application. In another example, audio may be received from a remote device through a wireless connection. Multiple streams of audio content may be mixed together prior to storing with video. The audio, upon reception, may then be routed to the video capture application for recordation. An audio progression bar may also be provided to indicate duration and elapsed time information associated with the audio being recorded.
