Slideshow Synchronization via Audio Play Interval Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slideshow technologies struggle to synchronize image and sound reproduction timings accurately, leading to incomplete and unsatisfactory user experiences due to manual operation requirements and limitations in controlling sound and image data reproduction.
Innovation Solution
An information processing apparatus and method that specifies a play interval for background music sound data and allocates image data to this interval, producing reproduction control information to ensure image data is reproduced only during the sound data's play interval, using meta data to synchronize image and sound reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual operation synchronization technique is used, then image and sound reproduction timings can coincide, but production time and cost increase significantly
Solution Approach 1:
The system automatically extracts timing information from audio metadata and generates synchronized slideshow content without requiring manual intervention. The apparatus self-performs the synchronization task by processing audio data to obtain timing information and automatically allocating image data accordingly, eliminating the need for manual operation while achieving precise synchronization.
Solution Approach 2:
The patent replaces manual mechanical synchronization operations with automated information processing. Instead of manual timing adjustment, the system uses metadata extraction and automatic timing information generation to achieve synchronization, substituting human labor with computational processes that operate on audio and image data.
2Adaptability or versatility
If control information is prepared in advance, then sound and image data can be associated, but reproduction timing cannot be controlled accurately for arbitrary content
Solution Approach 1:
The system performs preliminary extraction of timing information from audio metadata before the actual reproduction process. By pre-processing the audio data to obtain timing information and using this information to allocate image data in advance, the system enables accurate timing control for arbitrary content without requiring manual preparation for each specific reproduction instance.
Solution Approach 2:
The patent dynamically adjusts reproduction parameters based on extracted timing information from audio metadata. The system changes timing parameters automatically according to the audio content characteristics, allowing accurate synchronization for any arbitrary sound and image data combination without requiring pre-prepared control information for each specific case.
3Reliability
If slideshow content is produced manually for every tune and image, then synchronization is achieved, but skill requirement and complexity increase
Solution Approach 1:
The apparatus automatically performs synchronization by extracting timing information from audio metadata and generating coordinated image playback schedules without requiring user skill or manual intervention. The self-service mechanism handles the complex synchronization tasks automatically, reducing both skill requirements and process complexity while maintaining reliable synchronization accuracy.

AI summary
An information processing apparatus and method for providing images which coincide in reproduction time and atmosphere with BGM as a slideshow to a user. From sound data to be used for production of BGM, a head no-sound interval detection section detects a head no-sound interval and a tail no-sound interval detection section detects a tail no-sound interval while a tail fade-out interval detection section detects a tail fade-out interval. A play interval specification section specifies a play interval of the sound data other than the head and tail no-sound intervals, and an image content allocation section allocates photo album information and effect data to the play interval to produce vector data. A fade-out process setting section updates the vector data so that a fade-out process may be applied to images within the tail fade-out interval.
