Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3 DoF media content is directly rendered on a 6 DoF platform without conversion, then the rendering process is simple and fast, but the user interaction and immersion are limited and the content cannot be properly displayed
Solution Approach 1:
The patent transforms 3 DoF media content into 6 DoF content by changing the spatial parameter representation. Specifically, it converts spherical coordinate parameters (theta, phi, radius) into Cartesian coordinate parameters (x, y, z), enabling the content to be properly rendered on 6 DoF platforms while maintaining the original rendering simplicity through automated parameter transformation.
Solution Approach 2:
The patent introduces an intermediary conversion process that acts as a bridge between 3 DoF and 6 DoF platforms. The processing circuitry receives 3 DoF content, transforms it through coordinate system conversion using sphere parameters, and outputs 6 DoF content, thereby enabling compatibility without requiring complete re-rendering or complex platform-specific adjustments.
2Adaptability or versatility
If 3 DoF information is converted to 6 DoF information through coordinate transformation, then platform compatibility and user immersion are improved, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-defining sphere parameters (center location, radius) that are used in the coordinate transformation process. These pre-established parameters simplify the conversion calculation, as the processing circuitry only needs to perform straightforward mathematical transformations using the predetermined sphere geometry rather than calculating complex spatial relationships in real-time.
Solution Approach 2:
The conversion process utilizes parameter changes by transforming coordinates based on sphere geometric parameters (center location, radius). The processing circuitry changes the parameter representation from angular coordinates (theta, phi) to spatial coordinates (x, y, z) using the sphere's predefined parameters, making the transformation computationally efficient despite the increased processing requirements.
3Productivity
If predefined sphere parameters are used for conversion, then the processing is simplified and faster, but the accuracy and precision of spatial representation may be reduced
Solution Approach 1:
The patent resolves this contradiction by using parameter changes that maintain precision through mathematical relationships. The predefined sphere parameters (center location, radius) are used to establish a coordinate transformation system where the relationship between angular coordinates and spatial coordinates is precisely defined by the sphere geometry, ensuring accurate spatial representation while enabling efficient computation.
Solution Approach 2:
The patent replaces complex mechanical spatial calculation systems with mathematical parameter transformations. Instead of performing complex 3D spatial reasoning and coordinate transformations, the system uses predefined sphere parameters to substitute and simplify the calculation process, achieving both speed and precision through mathematical substitution rather than iterative computational methods.

AI summary
Aspects of the disclosure provide methods and apparatuses for audio processing. In some examples, an apparatus for media processing includes processing circuitry. The processing circuitry receives first 3 degrees of freedom (3 DoF) information associated with a first media content for a scene in a media application. The first 3 DoF information includes a first revolution orientation for describing the first media content on a first sphere centered at a user of the media application. The processing circuitry determines that a rendering platform for rendering the first media content is a six degrees of freedom (6 DoF) platform, and calculates, first spatial location information of the first media content based on the first revolution orientation and first parameters of the first sphere. The first spatial location information is used in first 6 DoF information associated with the first media content for rendering the first media content on the 6 DoF platform.
