Multimedia Platform Synchronizing Music and Video via Timing Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia platforms lack synchronization between visual images and music recordings, leading to asynchronous playback of pictures and tones during performance recording and reproduction, especially when using independent video cassette players and automatic recording/playing systems.
Innovation Solution
A multimedia platform that synchronizes music sounds with visual images by using multiple data sources for time data and video/image data, a timing controller to adjust and compare time data, and an image/sound generator to produce synchronized outputs, ensuring consistent playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent video cassette player and automatic recording/playing system are used to record picture and performance separately, then each device can function independently, but synchronization between picture and tones cannot be guaranteed
Solution Approach 1:
The patent merges previously independent recording systems (video cassette player and automatic recording/playing system) into a single integrated recorder that simultaneously records both video and audio data. This integration ensures that picture and tones are recorded together with synchronized timing, eliminating the synchronization problems that occurred when separate devices were used independently.
Solution Approach 2:
The recorder is designed as a multi-functional device that can simultaneously perform video recording, audio recording, and time-code generation. By consolidating multiple functions into one device, the system ensures that all recording operations are coordinated and synchronized, while still maintaining the ability to independently access and reproduce video or audio content.
2Adaptability or versatility
If multiple independent devices (video cassette player, compact disc player, automatic recorder/player system) are used for ensemble performance recording, then each device can process its data independently, but synchronization among picture, electronic tones, and acoustic tones cannot be guaranteed
Solution Approach 1:
The patent combines multiple independent recording functions into a single integrated recorder that handles video, electronic audio, and acoustic audio recording simultaneously. This unified approach ensures that all three data streams are captured with synchronized timing, eliminating the synchronization issues that arise when multiple independent devices operate separately.
Solution Approach 2:
The integrated recorder acts as an intermediary that coordinates and synchronizes multiple data streams (video, electronic audio, acoustic audio) that would otherwise be processed independently by separate devices. By centralizing the synchronization function within one device, the system ensures consistent timing across all media types.
3Quantity of substance
If video and audio data are recorded on separate storage media, then data can be stored independently, but time lag occurs during concurrent playback
Solution Approach 1:
The patent merges separate video and audio storage functions into a single integrated recording system that writes both data types to unified storage media with synchronized timing. This eliminates the time lag that occurs during playback when video and audio are read from separate independent storage devices, as the integrated system ensures both data streams are recorded and reproduced in precise temporal alignment.
Data Source
AI summary
A multimedia platform records a performance on a keyboard synchronously with a picture by periodically regulating an internal clock, which is indicative of the lapse of time, with time codes inserted into the set of video data codes representative of the picture, and reproduces the performance through an automatic player piano also synchronously with the picture by periodically regulating the internal clock with the time codes, whereby the user enjoys himself or herself in the performance as if he or she feels himself or herself performing in a convert hall.
