Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of hybrid services complicates the structure of service components, but there is no established technical scheme for selecting the optimal component for each service.
Innovation Solution
A reception device that can receive components via broadcast and network, and selectively choose the optimal component from multiple candidates based on adaptive and composite layer structures, using signaling information to dynamically switch between different bit rates and attributes such as resolution and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hybrid services are introduced to provide various services, then service versatility is improved, but component structure complexity increases
Solution Approach 1:
The service components are segmented into independent selectable units (video components, audio components, caption components) that can be individually received from broadcast or network sources. This segmentation allows the system to handle complexity by treating each component separately rather than as a monolithic structure.
Solution Approach 2:
The component selection structure is made dynamic through the use of selection tables and signaling information that enable real-time switching between broadcast and network components based on current conditions. The system can dynamically adapt component sources without requiring a complete structural redesign.
2Adaptability or versatility
If multiple component candidates are received from both broadcast and network, then component selection flexibility is improved, but system complexity increases
Solution Approach 1:
Selection tables are prepared in advance containing information about available components from both broadcast and network sources. This preliminary organization of component information allows the system to make selection decisions without complex real-time analysis, reducing operational complexity while maintaining flexibility.
Solution Approach 2:
Signaling information acts as an intermediary that carries component identification and selection criteria between the broadcast/network sources and the selection logic. This intermediary structure simplifies the interaction between multiple component sources and the selection mechanism.
3Reliability
If optimal component selection is implemented based on current conditions, then service quality is improved, but processing complexity increases
Solution Approach 1:
The system uses signaling information that provides feedback about component availability, quality attributes, and selection criteria. This feedback mechanism enables automatic optimal component selection based on current reception conditions without requiring complex external control logic.
Solution Approach 2:
The reception device performs automatic component selection based on pre-configured selection tables and signaling information, without requiring manual intervention or complex external processing. The system serves itself by autonomously determining the optimal component configuration based on available information.

AI summary
The present invention relates to a reception device that can select an optimal component. The reception device includes a first reception unit that receives a video or audio component transmitted on a broadcast wave, a second reception unit that receives a video or audio component distributed via a network, and a control unit that controls the operation of each unit. The control unit selects the optimal video or audio component from a plurality of video and audio components that the reception device can receive.
