Reception Apparatus Time Correspondence Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving reliable content reproduction in client apparatuses where synchronization of time information between the transmission and reception sides is difficult, especially in environments where Network Time Protocol (NTP) cannot be used and system time cannot be easily changed.
Innovation Solution
A reception apparatus and data processing method that utilize time correspondence information by associating first time information from the transmission side with second time information generated on the reception side, allowing for reliable content reproduction through a control unit that manages and applies this information to synchronize content playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional time synchronization methods (NTP) are used, then time synchronization between transmission and reception sides can be achieved, but it becomes inapplicable in environments where NTP cannot be used or system time cannot be easily changed
Solution Approach 1:
The patent introduces time correspondence information as an intermediary mechanism that bridges the transmission side's first time information and the reception side's second time information. This mediator allows synchronization without requiring direct NTP communication or system time changes, resolving the contradiction between synchronization reliability and environmental adaptability
Solution Approach 2:
The patent segments the time synchronization problem into two independent time information systems (first time information from transmission side, second time information from reception side) that are then correlated through time correspondence information. This segmentation allows each side to maintain its own time system while achieving synchronization, enabling operation in environments where traditional unified time synchronization methods fail
2Reliability
If system time is changed to achieve synchronization, then time correspondence can be established, but it becomes difficult in environments where system time cannot be easily changed
Solution Approach 1:
Time correspondence information serves as a mediator that establishes the relationship between first and second time information without requiring actual system time changes. This intermediary mechanism achieves reliable content reproduction while avoiding the operational complexity of system time adjustment
Solution Approach 2:
The patent changes the approach from modifying system time parameters to establishing time correspondence relationships. By transforming the synchronization problem from a time parameter adjustment task to a correspondence establishment task, the system achieves reliability without the operational burden of system time changes

AI summary
The present technology relates to a reception apparatus and a data processing method that ensure reliable reproduction of content.The reception apparatus receives content, and controls reproduction of the content on the basis of time correspondence information associating first time information provided from a transmission side of the content with second time information generated on a reception side of the content by a time axis according to the first time information corresponding to the second time information. The present technology can be applied to a television receiver compatible with ATSC 3.0, for example.
