Video Clip Replacement via Data Fragmenter Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing video clips during live transmissions when transmission rights are unavailable result in unauthorized access risks and interrupt the video stream, failing to seamlessly bridge the gap without stopping the original content.
Innovation Solution
A method where a data fragmenter decides which clip to fragment and transmit, allowing the video stream to continue with only the audio signal intact, and encrypts the fragmented signal for secure delivery, enabling seamless replacement without stopping the original content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the video clip is stopped and an advertising clip is shown in the pause, then the advertising content can be delivered, but the video transmission is interrupted and the user experience is degraded
Solution Approach 1:
The patent introduces a replacement video clip as an intermediary content that bridges the gap between the original video clip segments. This mediator content allows the transmission to continue without interruption while still enabling advertising delivery, thus resolving the contradiction between maintaining video continuity and delivering advertising content efficiently
Solution Approach 2:
The patent segments the video content into multiple clips with replaceable sections. By dividing the video into separable segments, the system can replace specific portions with replacement clips containing advertising content while maintaining the overall continuity of the transmission, avoiding complete interruption
2Reliability
If the video clip is transmitted in its entirety to the user unit, then the complete content is available, but unauthorized storage and access risks arise
Solution Approach 1:
The patent divides the video content into multiple separate clips that are transmitted individually rather than as a complete file. This segmentation prevents unauthorized storage of the entire video while allowing flexible replacement of specific segments with advertising content, thus maintaining both security and transmission flexibility
Solution Approach 2:
The patent implements a dynamic transmission system where the content delivered to the user unit can be changed in real-time based on rights management decisions. The system can dynamically switch between original video clips and replacement clips containing advertising, providing adaptability while maintaining security through controlled delivery
3Loss of information
If a replacement clip is inserted by stopping the film, then advertising content can be delivered, but the transmission time is increased and live event coverage is delayed
Solution Approach 1:
The patent prepares replacement video clips containing advertising content in advance and makes them available for immediate insertion. By pre-processing the replacement content, the system can switch to replacement clips without interruption or delay, maintaining live transmission timing while delivering advertising content
Solution Approach 2:
The patent ensures continuous transmission by using replacement clips that maintain the video feed without interruption. The replacement clips are seamlessly integrated into the transmission stream, allowing advertising delivery to occur without stopping the film or causing delays in live event coverage
Data Source
AI summary
A method of feeding a replacement clip (12) into the ongoing transmission of a video clip (11), a first compressed video signal (1) comprising the video clip (11) being transmitted from a video source (9) to a data fragmenter (3), the data fragmenter (3) splitting the first video signal (1) into individual data fragments and then outputting a fragmented video signal (13) to a user terminal (7), the fragmented video signal (13) being transmitted over a data link (14) to a user terminal (7), at which the fragmented video signal (13) is decoded and the video clip (11 ) may be viewed by a user, a replacement clip (12) being displayed on the user terminal (7) in interrupt mode, the video clip (11) continuing to run during interrupt mode but not visibly for the user, wherein a second video signal (2) is provided for fragmentation to the data fragmenter (3) in parallel with and at the same time as the first video signal (1) during interrupt mode, wherein the second video signal (2) comprises the replacement clip (12) and wherein the second data signal (2) is fragmented instead of the first data signal (1).
