Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed captioning systems provide limited language options and asynchronous caption and video streaming, requiring significant transmission resources, especially when multiple language options are offered.
Innovation Solution
A system comprising a server and client devices that manage and transmit customized caption information in multiple languages, including translation and synchronization, using various communication protocols and frequency bands, allowing users to select preferred languages and ensuring synchronized display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional CC systems provide multiple language options, then language versatility is improved, but transmission resources are significantly increased
Solution Approach 1:
The patent segments the transmission of caption information by separating it from the video stream. Caption information is transmitted independently through a dedicated channel, allowing multiple language options without proportionally increasing the video transmission resources. This segmentation enables the system to provide language versatility while controlling transmission resource usage.
Solution Approach 2:
The patent introduces an intermediary mechanism where caption information is transmitted separately and then synchronized with the video stream at the receiving end. This intermediary approach allows the system to offer multiple language options without requiring simultaneous transmission of all language versions through the video channel, thus reducing the burden on transmission resources.
2Device complexity
If conventional CC systems generate caption information locally, then device complexity is reduced, but synchronization between captions and video becomes problematic
Solution Approach 1:
The patent implements a feedback mechanism where the receiving device receives caption information separately and then synchronizes it with the video stream based on timing information. The system uses feedback loops to adjust caption timing relative to the video, ensuring accurate synchronization even when captions are generated or transmitted through separate channels. This feedback approach maintains reliability while keeping local device complexity manageable.
3Ease of manufacture
If conventional CC systems transmit captions and videos in the same means, then transmission simplicity is maintained, but transmission efficiency decreases especially with multiple language options
Solution Approach 1:
The patent applies segmentation by dividing the transmission system into separate channels for video and caption information. This allows the system to maintain transmission simplicity through standardized protocols while significantly improving efficiency by avoiding redundant transmission of caption data for multiple language versions. The segmented approach enables selective transmission of only the required language options.
Solution Approach 2:
The patent implements partial action by transmitting only the necessary caption information for selected language options rather than all possible languages simultaneously. This selective transmission approach improves efficiency by reducing unnecessary data transmission while maintaining ease of manufacture through standardized caption transmission protocols.

AI summary
A technique is directed to methods and systems for managing caption information. In some implementations, the method includes (1) receiving, at a server, user information describing a user's preference of caption information; (2) generating, at the server, one or more sets of caption information based on the user information; (3) transmitting the one or more sets of caption information to a first client device via a first route; and (4) transmitting video content associated with the one or more sets of caption information to a second client device via a second route different than the first route.
