Video Translation Delay Synchronization for Real-Time Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video messaging translation technologies fail to provide real-time language translation, leading to delays and disruptions in video communication across language barriers.
Innovation Solution
A video messaging system that includes a translation processing application, which captures audio and video data, separates the visual and audio components, translates the audio in real-time, and synchronizes the translation with the visual component by imposing a delay equivalent to the computation time, allowing seamless communication across multiple languages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real-time translation is implemented, then language barrier communication is enabled, but noticeable delays occur in video communication
Solution Approach 1:
The system performs preliminary actions by capturing and buffering video frames before they are displayed, and by pre-processing audio signals for translation. This allows the translation computation to occur on already-captured data rather than requiring real-time processing during playback, thereby enabling translation without adding noticeable delay to the video communication experience.
2Adaptability or versatility
If translation computation is performed, then multi-language support is achieved, but synchronization between translation and visual component becomes difficult
Solution Approach 1:
The system employs feedback mechanisms by continuously monitoring the timing relationships between captured video frames, audio signals, and translated output. This feedback loop allows the system to dynamically adjust synchronization parameters and compensate for varying translation computation times, maintaining accurate synchronization between translated subtitles and the visual component without requiring complex manual configuration.
3Measurement precision
If audio and video are processed separately, then translation accuracy is improved, but integration and synchronization become more complex
Solution Approach 1:
The system applies segmentation by separating the processing of audio and video components into independent streams. Audio is captured and translated separately to ensure high translation accuracy, while video is captured and buffered independently. The segmented processed streams are then integrated through timestamp-based synchronization, which manages the integration complexity through automated timing coordination rather than complex manual synchronization.
Data Source
AI summary
Disclosed are various embodiments for translation of speech in a video messaging application. A segment of streaming video is decoded to separate the visual component from the audio component. The audio component is then converted to text, which may then be translated and converted to a translation output comprising a new language. In response, the translation output may be encoded with the previously separated visual component. A delay is imposed on the visual component to account for any delays that may arise in translation. The translated video may then be streamed to participants giving the appearance of real-time video conferencing.
