Solution Overview

Problem

Users experience frustration with poor navigational aids and frequent interruptions from advertising content in recorded video streams on wireless mobile terminals, hindering seamless viewing of broadcast programs and movies.

Innovation Solution

An electronic device with a video signal receiver and storage controller that identifies advertising content locations, records addressable chapter marks, and allows viewers to jump playback, displaying extracted subtitle text and snapshots at these marks, enabling easier navigation through recorded video streams.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If advertising content is interspersed in recorded video streams, then broadcasters can generate revenue, but user viewing experience deteriorates due to frequent interruptions

Engineering Contradiction:
Improveviewing continuityVSAvoidadvertising interruptions
Core Design Contradiction:
Loss of energyVSObject-generated harmful factors

Solution Approach 1:

The patent extracts advertising content from the video stream by identifying it through scene change detection and metadata analysis, then creates separate chapter marks for these extracted segments. This allows the main program content to be continuously playable while advertising segments are marked as skipable units, resolving the contradiction by removing interruptions while preserving revenue-generating capability through targeted ad delivery.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the video stream into distinct program content segments and advertising content segments by detecting scene changes and analyzing metadata. Each segment is assigned a chapter mark with specific attributes (program content marks vs. advertising marks), enabling selective playback control. This segmentation allows users to skip advertising segments while maintaining continuous viewing of program content.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If traditional navigational aids are used in recorded video, then basic playback control is available, but navigation precision deteriorates due to inability to locate specific content positions

Engineering Contradiction:
Improvecontent navigationVSAvoidlocation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent performs preliminary analysis of the video stream during recording to identify scene changes, detect advertising content, and generate chapter marks with precise temporal locations. This preliminary action creates a structured navigation framework that enables accurate content location during playback, resolving the contradiction by preparing navigation data in advance rather than relying on basic seek operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces chapter marks as an intermediary layer between the raw video stream and the user interface. These chapter marks serve as precise location markers that mediate between the continuous video data and discrete navigation requirements, enabling accurate content positioning without requiring complex analysis during playback.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If chapter marks are created for advertising content locations, then navigation precision improves, but device complexity increases due to additional processing requirements

Engineering Contradiction:
Improvecontent location precisionVSAvoidvideo processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies partial action by focusing chapter mark generation only on significant content boundaries (scene changes and advertising segments) rather than creating marks for every video event. This selective approach achieves sufficient navigation precision for content location while avoiding the complexity of comprehensive video analysis, resolving the contradiction by applying processing only where necessary.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent enables the video recording system to automatically generate chapter marks by utilizing its own existing capabilities (scene change detection, metadata analysis) without requiring external processing systems. The recording device performs self-service by creating its own navigation structure during the recording process, reducing overall system complexity while maintaining high location precision.

Inventive Principle:
Principle #25Self-service

AI summary

Various embodiments provide an electronic device that includes video storage memory, a video signal receiver, and a video storage controller. The video signal receiver is configured to receive a video stream containing advertising content and program/movie content from a broadcast source. The video storage controller is configured to identify locations of advertising content interspersed among program/movie content in the received video stream, and to record addressable chapter marks for the identified locations of the advertising content and a video stream that is based on the received video stream into the memory. The addressable chapter marks may be displayed on a display and used by a viewer to jump playback of the video stream between the chapter marks.
