Scene Change Detection for Selective DVR Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DVR systems require users to record entire programs, leading to storage issues and inefficient playback, as they lack the ability to record or playback specific scene types within content, such as action or comedy scenes, without manual navigation through trickplay functions.
Innovation Solution
Implementing scene change detection and metadata to identify and record or playback specific scene types, allowing users to record, play back, and search for content based on scene types like comedy, action, or romance, using systems and methods that characterize content segments and provide user interfaces for scene type selection and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If entire programs are recorded and stored at the DVR device, then users can access all content segments, but storage capacity becomes scarce quickly and users are prevented from recording other programs of interest
Solution Approach 1:
The patent divides content into scene segments based on scene change detection, allowing users to record only specific scenes of interest rather than entire programs. This segmentation enables efficient use of storage capacity while maintaining recording flexibility, as users can select individual scenes to record based on their interests.
Solution Approach 2:
The patent extracts and isolates specific scene segments from the complete program content. By identifying and extracting only the relevant scenes (e.g., action scenes, comedy scenes) based on scene change detection and user preferences, the system removes unnecessary content from recording, thereby conserving storage capacity for other programs.
2Ease of operation
If users manually press Record and Stop buttons during live transmission to capture short video segments, then specific segments can be recorded, but users must be present next to the DVR device and have prior knowledge of upcoming segments
Solution Approach 1:
The patent implements automatic scene change detection that monitors content in real-time without requiring user presence or manual intervention. The system autonomously identifies scene changes, determines scene types, and can automatically record selected scenes based on pre-set user preferences, eliminating the need for users to be physically present at the device during transmission.
Solution Approach 2:
The patent performs preliminary analysis of content characteristics and scene types before recording occurs. By detecting scene changes and identifying scene types in advance, the system prepares recording decisions ahead of time, allowing users to set preferences for specific scene types (e.g., action, comedy) without needing to have prior knowledge of upcoming segments during first viewing.
3Loss of time
If users use trickplay functions to search through content to find desired segments, then playback can be performed, but the process is time-consuming and inefficient
Solution Approach 1:
The patent segments content into identifiable scene units with metadata describing scene types. This segmentation allows users to directly navigate to specific scenes of interest through the segmented structure rather than using time-consuming trickplay functions to search through entire programs, significantly reducing playback time and improving navigation efficiency.
Solution Approach 2:
The patent introduces scene change detection and metadata as an intermediary layer between the raw content and the user. This intermediary provides structured information about scene types and locations, enabling users to quickly locate and access desired segments through the metadata index rather than manually searching through the entire content using trickplay functions.
4Adaptability or versatility
If current DVR interfaces are used, then entire programs must be recorded, but users cannot record or playback specific scene types such as action or comedy scenes
Solution Approach 1:
The patent segments content into scene-based units with associated metadata identifying scene types (e.g., action, comedy, drama). This segmentation enables the recording system to filter and select specific scene types for recording and playback, providing users with adaptability to access only the scene types they are interested in while maintaining a manageable system architecture based on established scene change detection techniques.

AI summary
Methods, systems, and computer readable media described herein may facilitate the characterization of content segments based on a type of content, thus providing a user with the flexibility to: record only the scene types of interest to the user; playback only the scene types of interest to the user; search a media library, wherein the results of the search will include a list of only the content having scene types of interest to the user; browse available user selected scenes from clients; reposition content to user interested scene type during playback; and/or generate a detailed listing of the content based on the scene types. Scene change detection and scene type metadata may be used to identify scene boundaries within a piece of content and to characterize a scene based on a scene type.
