Digital TV Plot Synopsis Extraction for Series Program Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital TV systems do not provide detailed information about series-type broadcast programs that have previously aired, limiting users' ability to view past episodes of serial programs.
Innovation Solution
A digital TV system and method that includes receiving a data stream with programming guides, extracting and storing plot synopsis data for series-type programs, allowing users to access and manage information about past, present, and future episodes, using a receiver, control unit, and memory to store and display this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If digital TV systems transmit broadcast signals with program guides, then users can view current and future program information, but users cannot access detailed information about past episodes of series-type programs
Solution Approach 1:
The system performs preliminary action by automatically extracting and storing plot synopsis data for series-type programs in advance. The microcomputer identifies series-type programs from the EIT data and stores their synopsis information in memory before users need to access them, enabling immediate retrieval without time delay.
Solution Approach 2:
The system creates a copy of the program information by extracting plot synopsis data from the broadcast signal and storing it in the memory device. This copied information allows users to access past program details without needing to re-access the original broadcast signal, resolving the information loss problem.
2Loss of information
If the system stores detailed program information for all channels, then users can access comprehensive program data, but the memory requirement increases significantly
Solution Approach 1:
The system extracts only the necessary information by selectively storing plot synopsis data specifically for series-type programs rather than all program information. The microcomputer identifies series-type programs through genre information in the EIT data and extracts only their synopsis data, reducing memory requirements while maintaining information completeness for relevant programs.
Solution Approach 2:
The system applies local quality by providing detailed program information selectively only for series-type programs where it is most needed, rather than uniformly for all programs. This targeted approach ensures comprehensive information availability for series programs while minimizing unnecessary memory consumption for non-series content.
3Loss of information
If the system provides detailed program guides for multiple channels, then users can view comprehensive broadcast information, but the interface complexity increases
Solution Approach 1:
The system segments the program guide interface by separating current/future program information from past series program information. The microcomputer manages different types of program data through distinct processing paths: EIT data for current/future programs and stored synopsis data for past series programs, creating an organized and manageable interface structure.
Solution Approach 2:
The microcomputer acts as an intermediary that automatically extracts, processes, and stores program information without requiring users to manually navigate complex interfaces. It mediates between the broadcast signal and user requests by pre-processing and organizing information in memory, simplifying the user interface while maintaining comprehensive information availability.
Data Source
AI summary
A method of organizing programming data includes receiving a data stream including programming guide, which includes information describing aspects of broadcast programming; extracting a plot synopsis data from the programming guide relating to a series-type genre broadcasting program; and storing the plot synopsis data in a memory.
