Multi-Format Decoder Using Universal Transformer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of multiple codecs in display apparatuses is hindered by the need for separate hardware components due to their unique hardware implementations, leading to increased chip size and cost.
Innovation Solution
A method and apparatus that convert a single-format decoder to a multi-format decoder by processing information about different codecs, determining similarities between their transform coefficients, and adding shifters, adders, or subtractors to facilitate image processing using a second codec, employing a partial-butterfly method and Fourier-related transforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate hardware components are implemented for each codec, then each codec can be processed independently with its unique transforming method, but the chip size and cost increase
Solution Approach 1:
The patent implements a universal transformer that can perform multiple transforming methods (DCT, DST, integer DCT, etc.) through a single hardware component. The transformer is designed to adaptively select and execute different transforming algorithms based on the codec type, eliminating the need for separate hardware components for each codec while maintaining full codec compatibility
Solution Approach 2:
The patent merges multiple separate transforming components (first transformer, second transformer, improved transformer) into a single integrated transformer unit. This consolidation combines the functionality of multiple codec-specific transformers into one unified component that can handle various transforming methods, thereby reducing chip size while preserving the ability to process different codecs
2Adaptability or versatility
If separate hardware components are implemented for each codec, then each codec's unique transforming method can be supported, but the manufacturing cost increases
Solution Approach 1:
The universal transformer is designed to support multiple codec types through a single hardware implementation. By incorporating adaptive control logic that can select between different transforming methods (DCT, DST, integer DCT), the system achieves multi-codec support without requiring separate hardware components for each codec, thereby reducing manufacturing complexity and cost
Solution Approach 2:
The transformer implementation uses parameter changes to adapt to different codec requirements. By dynamically adjusting transforming parameters and selecting different algorithm configurations based on the input codec type, the single transformer component can efficiently support multiple codecs with varying transforming methods, reducing the need for multiple specialized hardware components

AI summary
Disclosed are a method of designing to transform an a single-format decoder, which performs image processing on an image signal using a first codec, to a multi-format decoder, which performs image processing on an image signal using a second codec, and an electronic apparatus thereof. The method includes processing first information about the first codec and second information about the second codec to produce a first transform coefficient associated with the first codec and a second transform coefficient associated with the second codec, through a predetermined transform method; determining a similarity between the first transform coefficient associated with the first codec and the second transform coefficient associated with the second codec; and converting the single-format decoder to the multi-format decoder by adding at least one of a shifter, an adder, and a subtractor, based on the determined similarity. Consequently, a reduction in chip size and cost may be achieved.
