Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional communication systems lack flexibility and efficiency in signaling configuration, particularly in handling unforeseen issues and new technology innovations, with existing methods like XML and JSON being inefficient in bandwidth usage and not supporting fixed-length commands and data fields.
Innovation Solution
A system and method for generating and transmitting control information using a tree-based data structure with a service descriptor that specifies protocol versions, allowing audiovisual devices to ignore unsupported data and configure themselves to present multimedia streams efficiently, using a flexible and extensible signaling framework.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If XML or JSON formats are used for extensible data structuring, then the protocol can evolve over time and support new functionality, but the bandwidth efficiency deteriorates due to text-based overhead
Solution Approach 1:
The patent replaces text-based data formats (XML, JSON) with a binary encoding system. This substitution transforms the mechanical representation of data from human-readable text to compact binary form, achieving both extensibility through structured fields and improved bandwidth efficiency through reduced overhead.
Solution Approach 2:
The patent creates a composite data structure that combines fixed-length fields for efficiency with extensible elements for adaptability. The structure integrates version identifiers, command fields, and data portions in a unified binary format that maintains both backward compatibility and forward extensibility.
2Loss of energy
If traditional predefined data formats are used, then bandwidth efficiency is maintained, but the system cannot adapt to unforeseen problems or new technology innovations
Solution Approach 1:
The patent introduces dynamic elements into the data format through version identifiers and extensible field structures. The format can evolve over time by adding new fields or modifying existing ones while maintaining backward compatibility, allowing the system to adapt to new requirements without breaking existing implementations.
Solution Approach 2:
The patent segments the data structure into distinct functional components: version identifiers, command fields, and data portions. This segmentation allows each component to be independently modified or extended, enabling the system to adapt to new requirements while maintaining overall structure integrity and bandwidth efficiency.
3Adaptability or versatility
If variable-length fields are used to accommodate different data types, then adaptability improves, but the complexity of parsing and processing increases
Solution Approach 1:
The patent applies different structural qualities to different parts of the data format. Critical fields such as version identifiers and command codes use fixed-length encoding for simple, efficient parsing, while data-specific fields can vary in length to accommodate different data types. This local differentiation optimizes both adaptability and processing complexity.
