Layered Data Transmission with Independent Bit-Plane Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods in communication systems, particularly in future devices with limited computing and battery capacity, suffer from poor transmission robustness due to strong dependencies between different layers of data, which are not fully utilized until all previous layers are correctly received.
Innovation Solution
A data processing method involving layered transmission based on data grouping and bit layering, allowing independent decoding of layers to improve robustness and flexibility, utilizing internal data correlations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If layered transmission based on quality, space size, time or other existing layering manners is used, then data can be organized into multiple layers, but transmission robustness deteriorates because different layers are strongly dependent on each other and each layer can be fully utilized only after all previous layers are correctly obtained
Solution Approach 1:
The patent segments data into multiple groups based on data unit sizes, and further segments each group into multiple bit planes. This creates independent layers where each layer can be decoded separately without requiring previous layers to be correctly obtained first, thereby improving transmission robustness while reducing layer dependency complexity
Solution Approach 2:
The patent introduces a new dimension of layering by organizing data into groups and bit planes, creating a two-dimensional layering structure. This allows independent decoding of each layer along both dimensions, breaking the strong sequential dependency of traditional layering methods and improving transmission reliability
2Reliability
If layered transmission with strong layer dependency is used, then data organization is simplified, but transmission robustness deteriorates because burst errors cannot be effectively coped with and each layer must wait for all previous layers
Solution Approach 1:
By segmenting data into independent groups and bit planes, the patent eliminates the sequential waiting dependency. Each layer can be decoded independently without waiting for previous layers, reducing decoding waiting time and improving robustness against burst errors through parallel processing capability
Solution Approach 2:
The patent performs preliminary organization of data into groups and bit planes before transmission, creating a structure that enables independent layer decoding. This preliminary segmentation allows receiving devices to decode and utilize available layers immediately without waiting for the complete layer sequence, reducing time loss

AI summary
A data processing method: A first apparatus performs layering processing on first data based on layering information to obtain N layers of data, where N is an integer greater than or equal to 2, and the layering processing includes data grouping and bit layering. The first apparatus separately performs coding and modulation on the N layers of data to obtain N bitstreams. The first apparatus sends the N bitstreams to a second apparatus.
