Video Remote-Commentary Synchronization via Sequence Number Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video commentary systems cannot facilitate remote commentary by multiple commentators on the same video, requiring physical gathering of commentators and limiting the implementation of synchronized commentary in various scenarios.
Innovation Solution
A video remote-commentary synchronization method and system that involves receiving and determining video and commentary voice sequence numbers, generating correlation tuples, and sending these correlations to a video playback end to synchronize the playback of commentary voices with video data, allowing independent commentary ends to play commentary voices without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If commentators are gathered together to give commentary on a video, then the commentary can be synchronized, but remote commentary by multiple commentators cannot be implemented
Solution Approach 1:
The patent introduces a server as an intermediary component that receives video data from a first terminal device, generates synchronization information, and transmits it to a second terminal device. This intermediary enables remote commentary synchronization without requiring commentators to be physically gathered together, resolving the contradiction between adaptability and system complexity.
Solution Approach 2:
The patent replaces the mechanical approach of physically gathering commentators in the same location with an information-based synchronization system. Instead of relying on physical proximity for synchronization, the system uses sequence numbers and timing information transmitted through communication networks, enabling remote commentary while maintaining synchronization.
2Adaptability or versatility
If multiple commentators remotely comment on the same video, then commentary versatility improves, but synchronization difficulty increases
Solution Approach 1:
The patent segments the video data into discrete units with associated sequence numbers and timing information. By breaking down the continuous video stream into manageable segments with identifiable markers, the system can precisely track and synchronize multiple commentary tracks with the video, making synchronization measurable and controllable.
Solution Approach 2:
The server receives synchronization status information from terminal devices and adjusts timing information accordingly. This feedback mechanism allows the system to detect synchronization state and make real-time adjustments, maintaining precise synchronization across multiple remote commentators while managing system complexity.

AI summary
To-be-commented video data is received by a terminal device, and a video sequence number of the to-be-commented video data is determined, which steps further include comprising, by the video data, a first correlation 2-tuple of a global base sequence number and the video sequence number, in which a sequence number of a live voice in the video data is the global base sequence number, and the video sequence number of the video data is determined according to the global base sequence number; and determining a video sequence number of the to-be-commented video data according to the first correlation 2-tuple. The to-be-commented video data is played, a commentary voice is acquired, and a correspondence between a voice sequence number of the commentary voice and the video sequence number is determined. The correspondence between the voice sequence number and the video sequence number is sent to a video playback end.
