Broadcast TS Transmission Device for Local Element Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadcasting systems lack a method for efficient distribution of data broadcast program contents to multiple broadcast stations, requiring each station to produce all structural elements of the data broadcast program content, which increases production costs and complexity.
Innovation Solution
A data broadcast program TS transmission device that receives a first transport stream, separates and judges source elements based on a judgment list, and outputs a data broadcast program transport stream including only the required elements, allowing for local element replacement and supplementation to create a unique broadcast program, while maintaining bandwidth and response time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each broadcast station produces all structural elements of data broadcast program content, then the broadcast program can be fully provided, but production costs and complexity increase
Solution Approach 1:
The patent divides data broadcast program content into discrete source elements (such as modules, resources, and event messages) that can be independently separated and selected. This segmentation allows broadcast stations to receive a complete set of source elements from a key station and then selectively process only the elements needed for their local broadcast, reducing production complexity while maintaining program completeness.
Solution Approach 2:
The patent extracts source elements from the received transport stream based on a judgment list that indicates which elements should be included in the local broadcast. This extraction mechanism enables broadcast stations to remove unnecessary elements and retain only required ones, thereby reducing production costs and complexity while preserving the essential content.
2Reliability
If each broadcast station produces all structural elements of data broadcast program content, then the broadcast program can be fully provided, but production costs increase
Solution Approach 1:
By segmenting the data broadcast program into identifiable source elements with associated identifiers, the system enables cost-effective production. Broadcast stations receive a master set of elements and only process those marked for inclusion in their local broadcast, significantly reducing the resources required for production while maintaining complete program coverage.
Solution Approach 2:
The extraction of only required source elements based on judgment lists directly reduces production costs. Instead of producing all possible elements, each station extracts and processes only the subset needed for their audience, eliminating wasted resources on unnecessary content while preserving program completeness.
3Ease of manufacture
If source elements are separated and selected based on judgment list, then production costs are reduced, but the process complexity increases
Solution Approach 1:
The judgment list is prepared in advance before the actual element separation process. This preliminary action defines exactly which source elements should be extracted and processed, simplifying the subsequent processing steps. The broadcast station only needs to follow the pre-established judgment list rather than making real-time decisions about element selection, reducing processing complexity.
Solution Approach 2:
The system uses feedback mechanisms where the separation judgment unit references the judgment list (which contains information about which elements should be included) to guide the separation process. This feedback loop ensures accurate and efficient element selection, reducing the cognitive load and processing complexity required during broadcast production.
4Adaptability or versatility
If local elements are replaced in the data broadcast program, then a unique broadcast program is created, but processing time increases
Solution Approach 1:
By segmenting the broadcast program into discrete replaceable elements, the system enables efficient local customization. Each element has a clear identifier and can be independently replaced with local equivalents, minimizing the processing time required compared to regenerating the entire program. The segmented structure allows parallel processing of multiple elements simultaneously.
Solution Approach 2:
Local elements are prepared and stored in advance before the replacement process. This preliminary preparation of local content means that when replacement is needed, the system only needs to substitute existing pre-prepared elements rather than creating them during broadcast, significantly reducing processing time while maintaining program uniqueness.
Data Source
AI summary
A data broadcast program transport stream (TS) transmission device provided in a broadcast station, and for transmitting a data broadcast program TS based on a data broadcast program TS distributed over a network by another broadcast station. The data broadcast program TS transmission device stores a selection list that shows whether data broadcast program elements of the received data broadcast program are for inclusion in the data broadcast program TS of the broadcast station, and a replacement list that shows the replacement of data broadcast program elements for inclusion with local program elements produced in the broadcast station. A separation judgment unit separates TS packets from the received data broadcast program TS, refers to the selection list, and notifies the replacement execution unit of data broadcast program elements for inclusion. Furthermore, if data broadcast program elements judged for inclusion are shown for replacement in the replacement list, the separation judgment unit sends a replacement instruction to the replacement execution unit. The replacement execution unit reads the local program elements indicated in the replacement instruction from the program element storage unit, generates TS packets, and outputs the generated TS packets together with selected TS packets to a multiplexing device as the data broadcast program TS of the broadcast station.
