Two-Stage Video Mode Selection for Standard Adaptation

Solution Overview

Problem

Existing video encoding devices require significant cost and time to remodel when adapting to new standards, as they need to be reconfigured with new hardware components.

Innovation Solution

A video encoding method and device that employs a two-stage mode selection process, using a first mode selector to choose a candidate mode from a predetermined group and a second mode selector to select an encoding mode from a different standard's group, allowing for encoding without evaluating all modes of the new standard.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If hardware components are remodeled to comply with a new standard, then compliance with the new standard is achieved, but cost and time for remodeling increase enormously

Engineering Contradiction:

Improvecompliance with new standardVSAvoidremodeling time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The mode determination process is divided into two independent stages: a first mode determination unit that operates independently of the standard, and a second mode determination unit that is remodeled for each new standard. This segmentation allows the first unit to remain unchanged while only the second unit requires remodeling for new standard compliance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first mode determination unit is designed with universal functionality that can operate across multiple video coding standards without modification. It determines candidate modes in a standard-independent manner, making it a reusable component that serves all standards.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If all modes of the new standard are evaluated, then encoding optimality is achieved, but processing time increases

Engineering Contradiction:

Improveencoding optimalityVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The first mode determination unit performs preliminary mode determination to identify candidate modes before the second unit selects the final encoding mode. This preliminary action narrows down the search space, allowing the system to achieve encoding optimality by evaluating fewer modes while maintaining processing efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of evaluating all possible modes, the system performs partial evaluation by first identifying candidate modes from a reduced set determined by the first unit, then selecting from those candidates. This partial action approach achieves sufficient encoding optimality without the excessive processing time required for complete mode evaluation.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A video encoding method includes a first mode selection step of selecting at least one mode as a first candidate mode from a predetermined first mode group for encoding a video, a second mode selection step of selecting one mode as an encoding mode from a predetermined second mode group, based on the selected first candidate mode, and an encoding step of encoding the video in the selected encoding mode.
