Transition File Metadata for Low-Latency Video Cue Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network services face challenges in efficiently integrating transition frames with user-requested content to seamlessly present additional content, leading to increased latency and reduced quality of content presentation.
Innovation Solution
A transition file is generated based on metadata about user-requested content and cue points, ensuring appropriate transition frames are included to manage the transition between user-requested content and additional content, such as advertisements, thereby reducing runtime determination latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transition frames are determined at runtime, then the content presentation can be dynamically adapted, but the latency increases and quality of service deteriorates
Solution Approach 1:
The patent applies preliminary action by determining transition frame parameters (duration, visual properties) in advance based on content metadata and cue points, storing them in a configuration file before content delivery. This pre-computation eliminates runtime determination latency while preserving the ability to adapt content presentation dynamically through the stored configuration.
2Reliability
If transition frames are included in the content file, then the transition quality is improved, but the file size and complexity increase
Solution Approach 1:
The patent segments the content delivery system into separate components: the original content file, a separate configuration file containing transition frame parameters, and a content presentation application that combines them. This segmentation maintains transition quality through dedicated transition frames while reducing the complexity of individual files and enabling independent processing of each component.
Solution Approach 2:
The configuration file acts as an intermediary that bridges the original content file and the content presentation application. It contains metadata and transition frame parameters that guide the presentation application in seamlessly integrating transition frames without requiring direct modification of the original content file, thus maintaining quality while managing complexity.
3Productivity
If transition frames are processed at runtime, then the responsiveness to user content can be optimized, but the processing time and system resources increase
Solution Approach 1:
The system performs preliminary processing by analyzing content metadata and cue points to determine transition frame parameters before content delivery. The configuration file is generated in advance containing all necessary transition specifications, which the content presentation application simply retrieves and applies during playback, significantly reducing runtime processing requirements and improving overall productivity.
Data Source
AI summary
Techniques for transition files for use with content files and related metadata are described. In an example, a system determines a cue point of a video content file at which targeted content is to be presented. The system determines that a set of transition frames is to be presented at a start of a presentation of the targeted content or at an end of the presentation of the targeted content. The set of transition frames are available from a transition file that is separate from the video content file. The system generates metadata associated with the video content file. The metadata indicates that the set of transition frames is to be presented and an association of the set of transition frames with the cue point.
