Transmission Stream Multiplexing for Hybrid Component Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcasting systems lack ease of component selection in hybrid broadcasting/communication systems, particularly in transitioning between different transmission paths.
Innovation Solution
A transmission device generates a transmission stream with multiplexed packets containing component data and signaling information, allowing for component selection through a component structure table and adaptive layer switching, and a reception device processes these packets to facilitate easy selection and presentation of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If component selection information is not provided in the transmission stream, then the transmission stream structure remains simple, but the reception side cannot easily select components in hybrid broadcasting/communication systems
Solution Approach 1:
The patent applies preliminary action by inserting component selection information (CST - Component Structure Table) into the transmission stream in advance, before the reception device needs to make component selections. This allows the reception device to have all necessary component information available upfront, enabling easy component selection without requiring additional information requests or complex processing during runtime.
2Adaptability or versatility
If multiple components are transmitted through multiple transmission paths, then component delivery flexibility increases, but component selection and composition at the reception side becomes complex
Solution Approach 1:
The patent merges component information from multiple transmission paths into a unified Component Structure Table (CST) that is inserted into the transmission stream. This consolidation allows the reception device to manage and select components from multiple sources (broadcasting and communication paths) through a single, organized structure, significantly reducing the complexity of component selection and composition while maintaining transmission path flexibility.
3Ease of operation
If component selection information is inserted into the transmission stream, then component selection ease at reception side improves, but the transmission stream structure becomes more complex
Solution Approach 1:
The patent segments the transmission stream into distinct components: regular transmission packets and signaling information packets. The component selection information (CST) is inserted as a separate signaling information packet, clearly demarcated from the main component data. This segmentation allows the reception device to easily identify and process the component selection information without being overwhelmed by the overall stream complexity, while maintaining a relatively simple and organized transmission stream structure.

AI summary
To secure easiness of component selection at a reception side. A transmission stream is generated in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner.
