Live Broadcast Audio Translation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users watching live video broadcasts from around the world may not understand the language of the host, leading to a poor viewing experience due to the lack of real-time language translation during live broadcasts.
Innovation Solution
A live broadcast processing method that receives source media data, translates audio data into target languages, acquires the required playing language based on the viewer's location, and merges it with video data to create target media data for transmission to the viewer's terminal, enabling simultaneous multi-language broadcasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio data is translated into multiple target languages for global viewers, then the adaptability and viewing experience for international audiences is improved, but the processing complexity and time required for live broadcast increases
Solution Approach 1:
The system performs preliminary actions by pre-translating audio data into multiple target languages before the live broadcast begins. The translation service pre-processes the content and stores translated audio segments, so that when viewers from different regions access the broadcast, their language preferences can be immediately satisfied without real-time translation delays, thus improving adaptability while managing processing complexity.
Solution Approach 2:
A translation service acts as an intermediary between the original audio content and the diverse audience. This intermediary component handles the language conversion process, allowing the main broadcast system to remain relatively simple while the translation service manages the complexity of multi-language support. The intermediary translates and adapts content for different regions without requiring the entire system to become overly complex.
2Ease of operation
If real-time language translation is implemented during live broadcast, then the viewing experience for non-native speakers is improved, but the broadcast delay and processing time increase
Solution Approach 1:
Translation services pre-translate content before it is broadcast, so that when viewers access the live broadcast, the translated audio is already ready for immediate playback. This preliminary translation action eliminates real-time translation delays, maintaining both high viewing experience quality and minimal broadcast delay by performing the time-consuming translation work in advance.
3Adaptability or versatility
If multi-language audio tracks are prepared and stored for different regions, then the adaptability to different audiences is improved, but the storage requirements and data management complexity increase
Solution Approach 1:
The system creates a universal broadcast framework that can serve multiple regions and languages through a single infrastructure. Instead of maintaining completely separate broadcast systems for each language, the platform uses a universal architecture that accommodates multiple language tracks, allowing the same broadcast content to be delivered to diverse audiences efficiently. This multi-functionality reduces the need for duplicate storage and management systems.
Solution Approach 2:
Translated audio content is pre-processed and stored in an organized manner before distribution. The system prepares multiple language versions in advance and stores them with efficient indexing and metadata, enabling quick retrieval and delivery based on viewer location and preference. This preliminary organization reduces the actual data that needs to be actively managed during broadcast while maintaining comprehensive multi-language support.

AI summary
The present application provides a live broadcast processing method, an apparatus, a device, and a storage medium thereof, where the method includes: receiving, by a live broadcast server, source media data sent by a first terminal device of a video live broadcast side, where the source media data includes video data and audio data; translating the audio data into audio data in at least one target language; acquiring a playing language required by a video playing side, and acquiring audio data corresponding to the playing language from the audio data in the at least one target language; merging the audio data corresponding to the playing language with the video data to obtain target media data; and transmitting the target media data to a second terminal device of the video playing side for playback.
