Audio-Video Endpoint Transitions for Seamless Interactive Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive media presentations experience noticeable disconnects or delays in audio and video transitions between segments, whether through immediate transitions that are abrupt or delayed until the end of the current segment.
Innovation Solution
Implementing defined endpoints within a decision period that allow seamless transitions by linking points in video segments, enabling immediate playback to the next segment upon reaching a predefined endpoint, often with interim segments to ensure continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If immediate transition to a different video segment is implemented upon user selection, then the response speed to user interaction is improved, but the audio and video continuity deteriorates resulting in noticeable disconnects
Solution Approach 1:
The system pre-loads and buffers multiple video segments and audio tracks in advance, preparing transition materials before the user makes a selection. This preliminary action enables the system to execute seamless transitions quickly when needed, resolving the contradiction between fast response and continuous playback by having all necessary transition resources ready beforehand.
Solution Approach 2:
The patent introduces intermediary transition segments and buffer zones between video segments that serve as mediators to bridge the gap between immediate user selection and continuous playback. These intermediary elements mask the transition points and create smooth transitions that maintain audio-video continuity while still responding quickly to user interactions.
2Reliability
If transition is delayed until the end of the current video segment to maintain seamlessness, then the audio and video continuity is improved, but the user experience deteriorates due to delayed response
Solution Approach 1:
The system performs preliminary actions by pre-loading next video segments and preparing transition metadata during the playback of current segments. This allows the system to transition immediately when users make selections without waiting for the current segment to end, thereby reducing perceived delay while maintaining continuity through prepared transition infrastructure.
Solution Approach 2:
The patent implements dynamic transition timing that adapts to user interaction patterns. The system can pause, resume, or accelerate playback based on user selections made during decision periods, creating flexible timing that maintains both continuity and responsiveness. This dynamic approach allows the system to optimize transition timing based on real-time user behavior rather than following fixed schedules.
3Adaptability or versatility
If multiple video segments are quickly transitioned upon user selection, then the interactivity and responsiveness are improved, but the audio and video synchronization deteriorates causing noticeable disconnects
Solution Approach 1:
The system pre-loads multiple video segments with their associated audio tracks and transition metadata in advance, creating a ready-to-playback library. This preliminary preparation enables the system to quickly switch between segments while maintaining synchronization by having all audio-video pairs pre-coordinated, thus resolving the contradiction between rapid interactivity and synchronization reliability.
Solution Approach 2:
The patent implements feedback mechanisms that track user interactions and adjust playback timing accordingly. The system monitors user selections and provides feedback by adjusting transition timing and buffering strategies to maintain audio-video sync. This feedback loop ensures that rapid transitions respond to user input while preserving synchronization through continuous adaptation based on observed user behavior patterns.

AI summary
To provide for seamless audio, video, and contextual transitions in interactive media presentations, endpoints within the presentation are defined. The endpoints are disposed at different times within the presentation and form respective links between points in segments in the presentation. While the presentation is being played, a user interaction is received and an appropriate endpoint is selected based on the interaction. When the selected endpoint is reached, the presentation is seamlessly transitioned to the point in the segment linked to by the endpoint.
