Guided Video Playback With Real-Time Query Responses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback methods require inefficient navigation, such as pausing and rewinding, to find relevant content, leading to extended playback time, increased computational cost, and reduced user engagement.
Innovation Solution
Implementing a system that generates guided content, including summaries and question prompts, using multi-modal neural networks to enhance video playback efficiency by providing tailored content during playback, minimizing navigation and reducing computational overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users navigate video repeatedly (pause, rewind, skip) to find relevant content, then they can locate specific information, but total playback time increases and computational cost increases
Solution Approach 1:
The system performs preliminary analysis of the video content before playback to generate a comprehensive content index and structured representation. This pre-processing enables users to directly navigate to relevant segments without repeated pausing and rewinding, as the content metadata is already organized and searchable.
Solution Approach 2:
The system introduces an intermediary layer between the user and the video content - a content understanding system that analyzes video semantics, objects, actions, and relationships. This intermediary provides structured content metadata that enables efficient navigation and direct access to relevant portions without manual scrubbing.
2Reliability
If users navigate video repeatedly to understand content, then they can review portions, but computational overhead increases due to redundant decoding
Solution Approach 1:
The system performs content analysis and generates structured metadata before playback begins. This preliminary processing creates an efficient representation of video content that can be queried and displayed without requiring repeated video decoding, significantly reducing computational overhead during user review operations.
Solution Approach 2:
The system creates a simplified copy or representation of the video content in the form of structured metadata, content indices, and semantic annotations. This copy contains essential information about objects, actions, and relationships, allowing users to understand and review content without repeatedly decoding the full video stream.
3Ease of operation
If video is streamed from server during repeated navigation, then users can access content, but data transfer efficiency decreases due to wasteful transfers
Solution Approach 1:
The system generates and transmits content metadata and structural information before or during initial video loading. This preliminary data allows the user device to perform local content analysis and navigation decisions, reducing the need for repeated server communications and video segment requests during playback.
Solution Approach 2:
The system introduces a content indexing layer that acts as an intermediary between the video stream and the user interface. This intermediary provides a structured representation of video content that enables efficient client-side navigation and filtering, minimizing the need for repeated server requests and data transfers.
4Ease of manufacture
If users frequently pause and rewind video, then they can review content, but user engagement decreases and content reception is hindered
Solution Approach 1:
The system pre-processes video content to generate structured metadata about objects, actions, relationships, and key events. This preliminary organization allows users to quickly scan and understand video content through the generated summaries and indices, reducing the need for repetitive pausing and rewinding while maintaining comprehension.
Solution Approach 2:
The system replaces the mechanical interaction of manual video navigation (pausing, rewinding, scrubbing) with an intelligent content understanding system that automatically analyzes and structures video content. This substitution provides users with programmatic access to video information through queries and summaries, eliminating the need for repetitive manual navigation operations.

AI summary
Methods, systems, and apparatuses, including computer programs encoded on computer storage media, for processing a video to generate guided content. Then presenting the guided content during video playback along with responses to user queries. In particular, the described techniques use multi-modal neural networks to process the video to generate summaries, question prompts, responses to question prompts, and responses to user queries that take into account video context, previous user queries, or both. As a result, the described techniques increase video playback efficiency by presenting engaging guided content that enhance user video playback experience and by presenting responses to user queries that are maximally relevant to the user in real-time.
