Solution Overview

Problem

Existing video coding standards lack efficient mechanisms for signaling text description purpose information, leading to inefficiencies in video data processing and decoding.

Innovation Solution

1Productivity

If text description information messages are included in video coding standards, then video data processing efficiency is improved, but data redundancy increases

Engineering Contradiction:

Improvevideo data processing efficiencyVSAvoiddata redundancy

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent introduces syntax elements (txt_descr_id, txt_cancel_flag, txt_persistence_flag) that dynamically control the behavior and persistence of text description information. By changing the parameter states of these syntax elements, the system can adjust whether text descriptions are included, canceled, or persisted, thereby optimizing the balance between processing efficiency and data redundancy reduction.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic control mechanisms where text description information can be conditionally included or canceled based on runtime conditions. The txt_cancel_flag and txt_persistence_flag enable the system to adaptively manage text description persistence, allowing the coding system to dynamically adjust data representation based on content requirements and efficiency considerations.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If text description purpose information is signaled, then decoding accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvedecoding accuracyVSAvoidcoding structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments text description information into distinct syntax elements (txt_descr_id, txt_cancel_flag, txt_persistence_flag, and purpose information). This segmentation allows the decoder to process each element independently, improving decoding accuracy by ensuring proper interpretation of text description intent while managing complexity through modular syntax element handling.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a universal syntax structure that handles multiple functions: identifying text descriptions (txt_descr_id), controlling persistence (txt_persistence_flag), and indicating purpose. This multi-functional syntax element design improves decoding accuracy by providing comprehensive text description information while avoiding the need for separate complex structures for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If persistence control mechanisms are implemented, then information management precision is improved, but bitstream complexity increases

Engineering Contradiction:

Improveinformation management precisionVSAvoidbitstream structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by including the txt_persistence_flag and txt_cancel_flag in advance within the bitstream. These flags pre-establish the persistence state of text description information, allowing decoders to manage information precision without requiring complex runtime analysis. The persistence control is determined beforehand, simplifying the decoding process while maintaining high information management precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts persistence control functionality into dedicated syntax elements (txt_persistence_flag, txt_cancel_flag) that are separate from the main video data. This extraction allows precise control over text description persistence while keeping the core bitstream structure relatively simple, as the persistence management is handled by discrete, easily parseable flags.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A device may be configured to decode video data based on information included in a text description information message. In one example, a text description information message includes a syntax element indicating that the text description information message cancels a persistence of a previous text description information message with the same purpose as the text description information message. In one example, a text description information message includes a syntax element indicating that the text description information message cancels a persistence of a previous text description information message with the same identifier value as the text description information message.
