Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP transmission method is introduced to support various operation modes and content formats, then adaptability and versatility are improved, but device complexity increases due to lack of established technical systems
Solution Approach 1:
The patent segments the broadcasting wave into multiple packets, each containing specific data elements (service information, control signals, components). This segmentation allows the receiving device to process different operation modes by selectively handling specific packet types, thereby improving adaptability without requiring the entire system to be redesigned for each mode.
Solution Approach 2:
The patent creates a universal receiving device architecture that can handle multiple operation modes through a single integrated system. The device uses common components (receiving unit, processing unit, packaging unit) that can process different types of broadcasting content (IP-based and non-IP-based) using the same fundamental mechanisms, thus achieving multi-functionality without proportionally increasing complexity.
2Ease of operation
If components and control signals are processed in units of service based on IP addresses, then service delivery flexibility is improved, but processing complexity increases
Solution Approach 1:
The patent merges components and control signals into unified service packages identified by common IP addresses. Instead of processing components and control signals separately, the system combines them into integrated service units that can be handled as single entities, simplifying the processing logic while maintaining service-level flexibility.
Solution Approach 2:
The patent introduces an intermediary processing layer that sits between the raw packet reception and the final service delivery. This intermediary layer (processing unit) standardizes the handling of packets by providing a common interface for extracting and organizing service information, control signals, and components, thereby reducing processing complexity while enabling flexible service operation.
3Loss of information
If multiple control signals (first and second control signals) are transmitted through different layers, then information completeness is improved, but transmission complexity increases
Solution Approach 1:
The patent transmits control signals across different protocol layers (first control signal at higher layer, second control signal at lower layer), effectively using the vertical dimension of the protocol stack to distribute information. This multi-dimensional transmission approach ensures that control signals reach the receiving device through multiple pathways, improving information completeness while distributing the transmission complexity across standardized layer boundaries.

AI summary
A receiving device including a receiver and processing circuitry is provided. The receiver is configured to receive a broadcast stream. The broadcast stream includes a plurality of services. Each of the plurality of services includes one or a plurality of components and a first control signal transmitted by a unidirectional transport session. The processing circuitry is configured to process the one or the plurality of components constituting a particular service of the plurality of services included in the broadcast stream, and process the first control signal of the particular service received from signals transmitted by the unidirectional transport session according to an Internet Protocol (IP) address. Each of the plurality of services is associated with a different IP address that is contained in packets of the one or the plurality of components and the first control signal of the respective service, and in an IP layer.
