Audio File Track Segmentation for Efficient Data Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not efficiently acquire a predetermined type of audio data among multiple types of audio data in video content, lacking improvement in this aspect.
Innovation Solution
An information processing apparatus and method that acquires or generates audio data by dividing it into tracks based on types, with each track being successively arranged in a file for a predetermined length of time, allowing for efficient acquisition and playback of specific audio data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio data of multiple types is stored in a single mixed track, then the file structure is simple, but the efficiency of acquiring a predetermined type of audio data is poor
Solution Approach 1:
The patent divides audio data into multiple separate tracks according to different types (e.g., background music track, voice track, effect track). Each track contains audio data of a specific type, allowing the playback device to selectively acquire and play back only the needed audio types, thereby improving acquisition efficiency while maintaining clear organizational structure.
2Speed
If all audio data is loaded into memory for random access, then access speed is fast, but memory capacity requirements increase
Solution Approach 1:
The patent segments audio data into multiple tracks stored sequentially in the storage medium. The playback device reads only the specific track containing the needed audio type from the storage medium, avoiding the need to load all audio data into memory. This approach maintains fast access speed by directly reading from storage while significantly reducing memory capacity requirements.
3Productivity
If audio data is divided into multiple separate files, then acquisition efficiency is improved, but file management complexity increases
Solution Approach 1:
The patent merges multiple types of audio data into a single file but organizes them into separate tracks within that file. Each track is identified by a track ID, allowing the playback device to selectively access specific audio types through the track ID without needing to manage multiple separate files. This approach improves acquisition efficiency while simplifying file management.

AI summary
The present disclosure relates to an information processing apparatus and an information processing method which are capable of improving an efficiency of acquiring a predetermined type of audio data among a plurality of types of audio data. Audio data of a predetermined track is acquired in one audio file in which audio data of 3D audio is divided into a plurality of tracks depending on the type of 3D audio and the tracks are arranged, the audio data of each track being successively arranged in the file for a predetermined length of time. The present disclosure is applicable to, for example, an information processing system including a file generation device that generates a file, a Web server that records a file generated by the file generation device, and a video playback terminal that plays back a file.
