Broadcast Frame Header Mapping for Multi-Stream Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast communication systems face challenges in providing high-quality, multi-channel, broadband digital services due to limitations in data transmission and processing efficiency, particularly in handling various types of digital broadcast data streams.
Innovation Solution
A transmitting apparatus and method that generates frames with baseband packets including headers and payload data, allowing for signal processing and transmission of both transport streams and other data types like Internet packets, while a receiving apparatus processes these frames to extract and handle the data efficiently, improving data processing efficiency by mapping data to multiple signal processing paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of data streams (transport stream, IP packets, signaling packets) are transmitted through a single broadcast communication system, then the versatility and quality of digital broadcast services are improved, but the complexity of data transmission and processing increases
Solution Approach 1:
The patent segments different types of data streams (transport stream, IP packets, signaling packets) into separate processing paths within the transmitting apparatus. Each data type is handled by dedicated processing modules that generate appropriately formatted frames, reducing the complexity of unified processing while maintaining versatility in supporting multiple data types simultaneously
Solution Approach 2:
The transmitting apparatus employs a universal frame structure that can accommodate multiple data types through configurable parameters and fields. The same basic frame format is used for transport streams, IP packets, and signaling packets, with type-specific information embedded in standardized fields, allowing a single system to handle diverse data types without requiring separate transmission systems for each
2Productivity
If data is mapped to multiple signal processing paths for efficient transmission, then data processing efficiency is improved, but the complexity of the transmitting and receiving apparatus increases
Solution Approach 1:
The patent divides the data processing into multiple parallel signal processing paths, each optimized for specific data types. The transmitting apparatus includes separate processing modules for transport streams, IP packets, and signaling packets that operate concurrently, enabling efficient parallel processing while maintaining manageable complexity through modular design
Solution Approach 2:
The patent introduces standardized frame structures and header formats as intermediary elements between different data types and the transmission medium. These intermediate representations provide a common interface that simplifies the coordination between multiple processing paths, reducing the overall system complexity while enabling efficient parallel operation
