Solution Overview

Problem

Conventional cloud gaming systems face significant processing power consumption due to independent graphics rendering and media encoding processes, with video encoders requiring substantial computations for fade detection and analysis.

Innovation Solution

A weighted prediction mechanism is implemented to extract fade effects information during graphics video rendering and transmit it as metadata, facilitating efficient encoding by performing weight prediction computations on designated frames.

Engineering Contradictions & Design Principles

1Productivity

If conventional video encoding uses weighted prediction tool to improve coding efficiency for linear brightness variation, then coding efficiency is improved, but computation required to detect and analyze every picture increases significantly

Engineering Contradiction:

Improvecoding efficiencyVSAvoidcomputation power consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by performing weight prediction computations during the graphics rendering stage before video encoding begins. Fade effects information is extracted and transmitted as metadata alongside video frames, so that when video encoding occurs, the weight prediction has already been completed, eliminating the need for separate detection and analysis computations during encoding

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism where fade effects information is extracted during rendering and transmitted as metadata that mediates between the rendering process and encoding process. This metadata serves as a bridge that provides pre-computed weight prediction information to the encoder, reducing the computational burden on the encoding side

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If graphics rendering and media encoding are performed as two independent processes, then processing flexibility is maintained, but majority of processing power is consumed

Engineering Contradiction:

Improveprocessing flexibilityVSAvoidprocessing power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges graphics rendering and media encoding processes by integrating weight prediction computations into the rendering pipeline. The fade effects information extraction and metadata generation are combined with the rendering operations, allowing both processes to share computational resources and work synergistically rather than independently consuming processing power

Inventive Principle:

Principle #5Merging (Combining)
