Live Transcription Pipeline for Real-Time Multimedia Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transcribing multimedia content, such as video, are often unable to perform real-time or near-real-time transcription due to the separation of systems used for broadcasting and transcription, and machine-learning techniques are not adaptable for simultaneous transcription.
Innovation Solution
A system comprising a front-end interface, video ingest servers, encoders, a media cluster, a management module, a cloud-based system, and a content repository, which enables real-time transcription by integrating these components to align text with spoken words and allow simultaneous transcription across multiple locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If machine-learning or AI techniques are used for transcription, then transcription accuracy is improved, but real-time transcription capability deteriorates because these systems are separate from broadcasting systems
Solution Approach 1:
The patent combines the AI transcription system with the broadcasting system into a unified architecture. The transcription system is integrated directly into the content delivery pipeline, allowing machine-learning models to process audio streams in real-time as content is broadcast, eliminating the separation that previously prevented simultaneous high-accuracy transcription and real-time performance
Solution Approach 2:
The system performs preliminary actions by pre-loading and initializing transcription models and buffers before content delivery begins. Audio content is buffered and pre-processed where possible, and transcription models are warmed up in advance, enabling the system to achieve real-time transcription capability from the start of content delivery without initialization delays
2Measurement precision
If manual transcription is performed, then transcription accuracy is improved, but productivity deteriorates due to the time-consuming nature of manual processes
Solution Approach 1:
The patent replaces the mechanical manual transcription process with an automated electronic system combining AI speech-to-text models and natural language processing. This substitution maintains high transcription accuracy through sophisticated language understanding while dramatically improving productivity by processing content at machine speed without human intervention
Solution Approach 2:
The transcription system performs self-service by automatically transcribing, timing, and synchronizing content without requiring manual operation. The system autonomously manages the entire transcription workflow from audio input to synchronized text output, eliminating the need for human transcribers while maintaining accuracy through built-in quality assurance mechanisms
3Productivity
If transcription is performed in multiple locations simultaneously, then productivity is improved, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent implements a universal architecture where a single centralized transcription service can handle multiple content streams and delivery locations simultaneously. The system is designed to be multi-functional, processing different types of content (live streams, recorded content, various formats) through the same infrastructure, which simplifies coordination compared to having separate systems for each location
Solution Approach 2:
The system introduces intermediary components including centralized timing servers, synchronization protocols, and buffer management layers that mediate between multiple transcription processes and their respective delivery destinations. These intermediaries coordinate timing and data flow across locations, reducing the complexity of direct peer-to-peer coordination between multiple transcription systems
Data Source
AI summary
The present disclosure is generally directed to a tangible, non-transitory machine-readable medium that includes machine-readable instructions that, when executed, cause processing circuitry to receive a first indication of multimedia content and a second indication of whether the multimedia content is to be transcribed. The instructions cause the processing circuitry to send content generated from the multimedia content for transcription. The content includes an identifier associated with the multimedia content. Additionally, the instructions cause the processing circuitry to send a request for the content to be transcribed. The request includes or is indicative of the identifier. Moreover, the instructions cause the processing circuitry to receive a transcript for at least a portion of the content and generate transcript metadata that includes timing data and is indicative of text of the transcript. Lastly, the instructions cause the processing circuitry to send the transcript metadata to be combined with the multimedia content.
