Segmented Data Feeding for Broadcast Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data broadcasting in digital television lacks efficient mechanisms for synchronizing program progress information, requiring time-consuming coordination between television program creation and data broadcasting, and infrequent implementation of synchronized information services.
Innovation Solution
A feeding device and method that broadcast a program with segment data sequences containing segment validity periods and metadata to receiving devices via a broadcasting network, allowing for synchronized information presentation with the program progress, using an application control descriptor to request and deliver segment data sequences, including metadata about focus targets such as humans, things, or scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data broadcasting structure is used to provide program progress synchronization information service, then synchronized information can be displayed, but time-consuming coordination between television program creation and data broadcasting is required
Solution Approach 1:
The patent segments the data broadcasting into independent segment data units, each with its own validity period and synchronization information. This allows segment data to be created and distributed independently from program production, eliminating the need for time-consuming coordination while maintaining reliable synchronization through the validity period mechanism.
Solution Approach 2:
The patent implements preliminary action by pre-defining segment data with validity periods and synchronization metadata before program broadcast. The segment data is prepared in advance with all necessary synchronization information embedded, allowing receiving devices to automatically synchronize without real-time coordination during program creation.
2Reliability
If conventional data broadcasting is used for program progress synchronization, then information can be displayed, but implementation frequency is very low
Solution Approach 1:
By dividing data broadcasting into independent, self-contained segment data units with embedded validity periods, the system enables frequent, granular updates synchronized to program progress. Each segment can be independently created and broadcast, dramatically increasing implementation frequency compared to conventional whole-program data broadcasting approaches.
Solution Approach 2:
The patent introduces dynamic segment data with validity periods that can be continuously updated and refreshed during program broadcast. This dynamic structure allows frequent implementation of synchronized information services, as segment data can be regenerated and redistributed without requiring complete program re-broadcasting.
3Ease of manufacture
If segment data sequence with validity period is broadcast, then synchronized information service is easily realized, but data structure complexity increases
Solution Approach 1:
The patent applies segmentation by creating modular segment data units with standardized validity period and synchronization fields. This modular structure simplifies service realization through automated processing, while the regularized data format actually reduces overall complexity compared to custom, non-standardized data structures.
Solution Approach 2:
The patent uses parameter changes by embedding validity periods and synchronization metadata as standardized parameters within segment data. This parameter-based approach enables automated service realization through simple parameter matching and validation, reducing operational complexity despite adding structured data elements.

AI summary
In a broadcasting system of the present disclosure, a feeding device includes a broadcasting unit that broadcasts a program to a receiving device via a broadcasting network, and a feeding unit that feeds a segment data sequence containing at least one piece of segment data including a segment validity period indicating a synchronization period for progress of the program and metadata associated with the program in progress to the receiving device, and the receiving device includes a receiving unit that receives the program broadcast from the feeding device via the broadcasting network, an acquisition unit that acquires the segment data sequence fed from the feeding device, and a presentation unit that presents information about the program to a user in synchronization with the progress of the program based on the acquired segment data sequence.
