Program Communication Synchronizer for Audio Video Propagation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to synchronize audio/video content delivery between presentation devices and mobile devices accurately, as they do not account for differences in propagation times between these devices, leading to potential delays or mismatches in content presentation.
Innovation Solution
A method and system that utilize a program communication synchronizer to calculate and adjust the timing of audio/video content delivery based on propagation time differences between presentation devices and mobile devices, ensuring that the content is presented simultaneously on both types of devices by coordinating the communication of audio/video portions through separate transmitters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio/video content is communicated to presentation device and mobile device simultaneously without timing adjustment, then communication simplicity is maintained, but propagation time differences cause content presentation desynchronization
Solution Approach 1:
The system performs preliminary timing calculations and adjustments before content communication. The synchronizer device calculates propagation times to both the presentation device and mobile device in advance, determines the time difference, and pre-adjusts the communication timing. This preliminary action ensures that content arrives at both devices simultaneously without requiring complex real-time coordination during content delivery.
2Manufacturing precision
If propagation time differences are not accounted for, then system simplicity is maintained, but content delivery timing accuracy deteriorates
Solution Approach 1:
The synchronizer device implements a feedback mechanism by calculating the actual propagation times for content to reach both the presentation device and mobile device, comparing these times to determine the time difference, and using this feedback information to adjust the communication timing. This closed-loop approach ensures precise content delivery timing while minimizing presentation delays.

AI summary
A programming communication synchronizer (100) embodiment communicates a portion of a program to a receiving device (118) during a first time period, communicates a corresponding portion of the program to a mobile device (140) during a second time period, and coordinates the first time period with the second time period so that the portion of the program is deliverable to a presentation device (120) coupleable to the receiving device at approximately the same time the corresponding portion of the program is deliverable to the mobile device (140).
