Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time information is acquired from physical layer frame in IP transport scheme, then synchronization between sending and receiving sides is achieved, but data format conversion complexity increases between demodulation LSI and main SoC
Solution Approach 1:
The patent introduces an intermediary conversion process that transforms time information from the physical layer frame format into the payload data format. This intermediary conversion section acts as a mediator between the demodulation LSI and main SoC, enabling seamless data transport without requiring the main SoC to directly handle multiple format types, thus reducing overall system complexity while maintaining synchronization reliability
Solution Approach 2:
The patent applies parameter changes by transforming the data format parameters of time information. The conversion section changes the structural parameters of time information from physical layer frame format to payload format, making it compatible with upper layer processing requirements while preserving the synchronization functionality
2Productivity
If time information is converted into same data format as payload, then processing efficiency in upper layer is improved, but additional conversion process increases system complexity
Solution Approach 1:
The patent implements preliminary action by performing data format conversion of time information before it reaches the upper layer processing section. The conversion is done in advance during the data transport phase, so that when the upper layer processing section receives the time information, it is already in the required payload format, enabling efficient processing without requiring complex real-time format handling
Solution Approach 2:
The patent merges the time information conversion process with the existing data transport infrastructure. By integrating the conversion function into the data flow path between demodulation LSI and main SoC, the system utilizes existing hardware and protocol structures, avoiding the need for separate dedicated conversion systems and thereby limiting the increase in overall system complexity

AI summary
The present technology relates to a reception apparatus and a data processing method that permit efficient processing of time information.The reception apparatus receives a digital broadcasting signal based on an IP transport scheme, acquires time information from a physical layer frame transported in a physical layer of a protocol stack for the IP transport scheme, converts the acquired time information into the same data format as data provided in a payload of the physical layer frame, and outputs the converted time information to a processing section that performs a given process relating to an upper layer that is a layer higher than the physical layer. The present technology is applicable, for example, to a television receiver that supports an IP transport scheme.
