Variable Speed Media Substitution via Imperceptible Video Cue Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia recording technologies, such as DVRs and VCRs, record promotional content along with programmed content, making it difficult to deliver intelligible messages during fast-forward or rewind operations, as the promotional content is not distinguishable from the program content.
Innovation Solution
A system that detects video cues imperceptible during normal playback and selects alternative media, such as placards or flash messages, to be displayed during variable display rates, allowing for intelligible messages during fast-forward or rewind operations by inserting substitute content during promotional segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If promotional content is recorded along with programmed content without distinction, then recording simplicity is improved, but message intelligibility during variable speed operation deteriorates
Solution Approach 1:
The video stream is segmented into distinct promotional content segments and programmed content segments by detecting video cues (such as scene changes, black frames, or metadata markers). This segmentation allows the system to identify and separate promotional spots from the main program, enabling selective substitution during variable speed playback while maintaining simple recording operations.
Solution Approach 2:
An intermediary processing layer is introduced between recording and playback that detects video cues and manages content substitution. This intermediary component analyzes the recorded stream, identifies promotional segments through cue detection, and replaces them with alternative content during variable speed operation, thereby preserving message intelligibility without complicating the basic recording function.
2Loss of information
If alternative media substitution is implemented during variable speed operation, then message intelligibility is improved, but device complexity increases
Solution Approach 1:
Alternative promotional content is prepared and stored in advance, associated with specific video cues in the recorded program. During playback, when variable speed mode is detected, the system simply substitutes the pre-prepared alternative content at the identified cue locations, rather than generating or processing content in real-time. This preliminary preparation reduces the computational complexity during actual playback operations.
Solution Approach 2:
The system changes the playback parameter (speed) as the trigger for content substitution. When the playback speed parameter deviates from normal speed, the system automatically activates the alternative content substitution mechanism. This parameter-based control simplifies the decision logic compared to analyzing multiple conditions simultaneously.
3Productivity
If promotional content is displayed during fast-forward or rewind, then advertising revenue opportunities are improved, but content distinction capability must increase
Solution Approach 1:
The system utilizes visual characteristics such as color patterns, brightness levels, or specific visual markers in the video stream to identify promotional content. Promotional segments may have distinct visual properties (such as different color grading, overlay graphics, or standardized opening/closing sequences) that serve as detectable cues, enabling automated identification without complex analysis.
Solution Approach 2:
The system employs periodic scanning or sampling of the video stream at regular intervals to detect promotional content markers. By checking for specific patterns or metadata at predetermined intervals, the system can efficiently identify promotional segments without continuously analyzing every frame, thereby reducing the difficulty of content distinction while maintaining accurate identification.
Data Source
AI summary
A process that incorporates teachings of the subject disclosure may include, for example, detecting a video cue frame within the multimedia data. The video cue frame has an image portion including alternative multimedia content and an encoded message, wherein the alternative multimedia content is imperceptible at a display device during a normal display rate presentation. The alternative multimedia content is obtained from the video cue frame responsive to receiving a first selection of a first alternative display rate that differs from the normal display rate. The alternative multimedia content is provided for display at a display device based on the encoded message. Other embodiments are disclosed.
