Object-Based Audio Playback Using Common Preset ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In object-based audio services, users face the burden of setting different presets for each content, making it inconvenient to consecutively listen to audio contents with desired settings, as presets are typically producer-specific and require manual adjustment.
Innovation Solution
An apparatus and method that generate and playback object-based audio contents using a common preset ID, allowing for consecutive playback of multiple audio contents based on an identical audio preset, with a database storing audio presets and IDs, a preset generating unit creating audio presets with object attributes, and an encoding unit generating encoded audio contents, and a playback unit rendering audio objects based on selected presets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each content uses its own unique preset ID, then the producer can customize audio settings for each content, but the user faces burden of manual preset adjustment for each content
Solution Approach 1:
The patent creates a common preset ID that can be universally applied across multiple different audio contents. Instead of requiring separate preset IDs for each content, the system allows a single preset ID to control audio settings across multiple contents, making the preset system universal and eliminating the need for users to manually adjust presets for each content.
Solution Approach 2:
The patent introduces a preset management server as an intermediary between the content provider and the user terminal. This server stores and manages preset information, allowing the user terminal to retrieve and apply presets automatically without manual user intervention, thus resolving the contradiction between customization and ease of operation.
2Device complexity
If audio signals are synthesized into a single signal, then transmission is simplified, but the audience cannot control individual sound source features
Solution Approach 1:
The patent segments the audio signal into multiple independent audio objects, each representing a separate sound source. Instead of transmitting a single synthesized audio signal, the system transmits multiple segmented audio objects that can be independently processed and controlled at the receiving end, enabling individual sound source control while maintaining transmission efficiency.
3Adaptability or versatility
If multiple presets are created for each content, then audio playback flexibility is improved, but the user burden of setting presets for each content increases
Solution Approach 1:
The patent implements preliminary action by having the preset management server pre-store and manage preset information before the user needs it. The server prepares preset data in advance and makes it available for automatic retrieval by the user terminal, eliminating the need for users to spend time setting up presets manually for each content playback.
Solution Approach 2:
The system enables self-service by allowing the user terminal to automatically retrieve and apply presets from the preset management server without requiring manual user configuration. The terminal autonomously manages preset selection and application based on the stored preset information, saving user time and effort.
Data Source
AI summary
Disclosed are an apparatus and a method of providing contents. The apparatus of providing the contents may include a receiving unit to receive, from a contents provider, contents and information about a contents providing location, a local group setting unit to search for at least one cell based on the information about the contents providing location and to set the retrieved cell as a content providing location group of the contents, and a transmitting unit to transmit the contents to the set content providing location group. The object based audio contents may be consecutively replayed based on an identical audio preset.
