Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If video compression technologies are used to reduce data bandwidth, then storage and transmission efficiency is improved, but the complexity of encoding and decoding processes increases

Engineering Contradiction:

Improvedata bandwidthVSAvoidencoding and decoding process complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The video bit stream is segmented and encapsulated into video track data structures with specific configuration boxes (e.g., AVS3DecoderConfigurationRecord) that organize coding parameters systematically. This segmentation allows efficient access to specific parameters without processing the entire bit stream, reducing decoding complexity while maintaining compression efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Configuration information including coding standards, profiles, and reference image parameters is extracted and embedded in the video track data structure during the encoding phase. This preliminary organization of parameters enables the decoder to quickly access necessary information without complex analysis during playback, reducing decoding complexity.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If different coding policies are used to encode video sequences, then adaptability to different devices is improved, but the complexity of video track management increases

Engineering Contradiction:

Improvedevice compatibilityVSAvoidvideo track management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The video track data structure is designed as a universal container that can hold configuration information for multiple coding standards (AVS, H.264, H.265, etc.) and their various profiles. The standardized structure with configurable boxes allows the same data structure to serve multiple coding policies, enhancing device adaptability without requiring separate management systems for each standard.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The video track data structure acts as an intermediary layer between the encoded video bit stream and the playback device. It contains configuration boxes that translate and organize coding parameters from different standards into a unified format, enabling smooth adaptation to various devices without increasing management complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If configuration information is added to video bit streams to indicate coding characteristics, then storage and retrieval efficiency is improved, but the size of video track data increases

Engineering Contradiction:

Improvestorage and retrieval efficiencyVSAvoidvideo track data size

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

Only the essential configuration parameters needed for decoding and identification are extracted and embedded in the video track data structure. Non-essential or redundant parameters are omitted, ensuring that the added configuration information is minimal yet sufficient for efficient storage, retrieval, and playback across different devices.

Inventive Principle:

Principle #2Taking out (Extraction)

4Manufacturing precision

If reference image information is encapsulated in video tracks, then decoding accuracy is improved, but the complexity of data structure increases

Engineering Contradiction:

Improvedecoding accuracyVSAvoiddata structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

Reference image information is nested within the video track data structure as a configurable box (e.g., ReferenceImageBox) that contains specific parameters like image identifiers and reference relationships. This nested organization allows the data structure to maintain a clear hierarchical format, improving decoding accuracy through structured reference information while avoiding excessive complexity through systematic nesting.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A video processing method is provided. In the method, a video bit stream is obtained. Configuration information of the video bit stream is determined. The configuration information includes reference image information. The reference image information indicates (i) whether a video track corresponding to the video bit stream includes a reference image and (ii) whether the video track requires reference to the reference image. The video bit stream and the configuration information are encapsulated to obtain the video track.
