Video Token Synchronization via Segmented Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video streaming services, the synchronization between audio and video playback can be disrupted due to network bandwidth limitations or congestion, leading to deviations in timing between audio reproduction and token object rendering, especially when tokens are given by viewers.
Innovation Solution
A method where the terminal device of the distributor transmits video data and token information along with audio signals, using a reference time stamp to synchronize audio and video playback at the viewer's terminal, ensuring that audio and token object animations are rendered in sync.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data and token information are transmitted together with audio signals, then the synchronization between audio and video playback is improved, but the network bandwidth consumption increases
Solution Approach 1:
The patent segments the data transmission into separate channels: video data (including token information) is transmitted intermittently only when changes occur, while audio signals are transmitted continuously. This segmentation allows synchronization to be maintained through separate timing mechanisms (video change timing vs. audio continuous timing) without requiring all data to be transmitted simultaneously, thus reducing overall bandwidth consumption while maintaining playback synchronization.
Solution Approach 2:
The patent implements periodic action by transmitting video data intermittently based on periodic changes in video content (motion changes, token given/received events) rather than continuously. The terminal device transmits video data at specific intervals when changes occur, while audio is transmitted continuously. This periodic transmission approach maintains synchronization capability while significantly reducing network bandwidth consumption compared to continuous transmission of all data types.
2Quantity of substance
If video data is transmitted intermittently only when changes occur, then the network bandwidth consumption is reduced, but the synchronization timing between audio and video playback may deviate
Solution Approach 1:
The patent applies preliminary action by having the terminal device transmit a video change timing indicator to the other terminal device before actually transmitting the video data. This advance notification allows the receiving device to prepare for the incoming video update and adjust its playback timing accordingly, ensuring that even though video data is transmitted intermittently, the synchronization timing between audio and video remains coordinated without deviation.
3Reliability
If the terminal device buffers the audio signal to suppress communication failures, then the audio playback reliability is improved, but the timing deviation between audio reproduction and token object rendering increases
Solution Approach 1:
The patent implements feedback by having the terminal device transmit a video change timing indicator to the other terminal device. This feedback mechanism provides real-time information about when video changes occur, allowing the receiving device to adjust its audio playback timing dynamically based on the actual video state. This coordination prevents timing deviation between buffered audio reproduction and token object rendering, as the audio timing can be adjusted according to the video change timing feedback.
Data Source
AI summary
Methods and apparatus are disclosed for video transmission using tokens. According to one example, computer-readable storage media storing computer-readable instructions, which when executed by a computer having at least one processor, cause the computer to: generate a video including an animation of an avatar object of a distributor generated on the basis of motion data regarding a motion of the distributor and an animation of a token object given by a viewer to the distributor operating according to a predetermined rule; and transmit, toward a plurality of viewer terminals via a communication line, coordinate data including data regarding coordinates of the token object associated with a reference time, and audio data regarding a voice of the distributor associated with the reference time.
