METHODS, APPARATUS AND SYSTEM FOR RENDERING AN AUDIO PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240304194 titled 'METHODS, APPARATUS AND SYSTEM FOR RENDERING AN AUDIO PROGRAM

The abstract describes a method for generating a bitstream for an object-based audio program, consisting of containers with substream entities, object channels, and metadata frames.

  • The method involves determining object channels and providing related metadata.
  • Object channel frames and metadata frames are inserted into substream entities.
  • Presentation data is inserted into the presentation section of the first container.

Key Features and Innovation:

  • Generation of a bitstream for object-based audio programs.
  • Inclusion of object channels, metadata, and presentation data in the bitstream.

Potential Applications:

  • Object-based audio streaming services.
  • Interactive audio experiences in virtual reality.
  • Enhanced audio content production and distribution.

Problems Solved:

  • Efficient organization and transmission of object-based audio data.
  • Seamless integration of object channels and metadata in audio programs.

Benefits:

  • Improved audio quality and immersive experiences.
  • Enhanced flexibility and control over audio content.
  • Streamlined production and distribution processes for audio programs.

Commercial Applications:

  • Audio streaming platforms for object-based content.
  • Audio production software with object-based capabilities.
  • Virtual reality and gaming applications requiring interactive audio.

Prior Art: Prior art related to object-based audio technologies and bitstream generation methods can be found in research papers, patents, and industry publications.

Frequently Updated Research: Stay informed about advancements in object-based audio technologies, bitstream encoding methods, and applications in various industries.

Questions about Object-Based Audio Bitstream Generation:

1. How does the method determine object channels for the audio program? 2. What are the key components of the bitstream containers for object-based audio programs?


Original Abstract Submitted

a method for generating a bitstream indicative of an object based audio program is described. the bitstream comprises a sequence of containers. a first container of the sequence of containers comprises a plurality of substream entities for a plurality of substreams of the object based audio program and a presentation section. the method comprises determining a set of object channels. the method further comprises providing a set of object related metadata for the set of object channels. in addition, the method comprises inserting a first set of object channel frames and a first set of object related metadata frames into a respective set of substream entities of the first container. furthermore, the method comprises inserting presentation data into the presentation section.
