Solution Overview

Problem

Playout terminals waste processing resources by decoding all media tracks of volumetric media due to an inability to identify the association relationship between media tracks, even when only one track is needed for reconstruction.

Innovation Solution

A data processing method that involves obtaining and transmitting alternative relationship indication and attribute information to playout terminals, allowing them to identify and decode only the necessary playout group for volumetric media reconstruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the playout terminal decodes all media tracks of volumetric media, then the complete volumetric media can be reconstructed, but the processing resources of the playout terminal are wasted

Engineering Contradiction:

Improvecompleteness of volumetric media reconstructionVSAvoidprocessing resources of playout terminal

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts and transmits alternative relationship indication information and alternative attribute information from the volumetric media data to the playout terminal. This enables the terminal to identify and select only the necessary playout group without decoding all media tracks, thereby extracting only the essential components needed for reconstruction while discarding redundant ones.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The service device performs preliminary processing by organizing media tracks into multiple playout groups and pre-calculating the alternative relationship indication information and alternative attribute information before transmission. This preliminary action enables the playout terminal to make efficient selection decisions without performing complex analysis during runtime.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the playout terminal cannot identify the association relationship between media tracks, then it can process all tracks uniformly, but it cannot select only the necessary tracks for reconstruction

Engineering Contradiction:

Improveuniformity of processingVSAvoidefficiency of media track selection

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent introduces alternative relationship indication information and alternative attribute information as intermediary elements between the service device and playout terminal. These intermediaries carry the association relationship data, enabling the terminal to identify which media tracks have alternative relationships and make informed selection decisions without requiring complex analysis capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple playout groups are provided with alternative relationships, then the playout terminal can adaptively select the appropriate group, but the data structure becomes more complex

Engineering Contradiction:

Improveadaptive selection capability of playout terminalVSAvoiddata structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the volumetric media into multiple playout groups, where each group contains a subset of media tracks that can independently reconstruct the volumetric media. The alternative relationship indication information further segments the relationships between these groups, allowing the playout terminal to adaptively select the most appropriate group based on its capabilities and conditions.

Inventive Principle:

Principle #1Segmentation

AI summary

A data processing method for volumetric media is disclosed. The method includes: obtaining alternative relationship indication information and alternative attribute information between every two playout groups in at least two playout groups of volumetric media, the alternative relationship indication information being for indicating a media track pair having an alternative relationship in every two playout groups, and the alternative attribute information being for reflecting an attribute difference between media tracks in the media track pair having the alternative relationship; and transmitting the alternative relationship indication information and the alternative attribute information to a playout terminal, so as to instruct the playout terminal to identify a target playout group matching with the playout terminal from the at least two playout groups according to the alternative relationship indication information and the alternative attribute information, and to decode the target playout group to obtain the volumetric media.
