Trigger Parameters Table for Interactive TV Data Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern televisions and set-top boxes face limitations in receiving and processing additional data required for enhanced functions, such as electronic programming guides, due to data capacity constraints, necessitating either data reduction or external data sourcing.
Innovation Solution
The implementation of a trigger compaction method using a trigger parameters table (TPT) that extracts and processes triggers from closed caption data, allowing for efficient retrieval and execution of events associated with media content, enabling the reception apparatus to handle additional data through satellite, cable, terrestrial broadcasts, or internet sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional data is provided along with the television broadcast to enable enhanced functions, then the interactivity and functionality of the television system is improved, but the data capacity constraints of the broadcast channel are exceeded
Solution Approach 1:
The patent segments trigger data into two parts: compact trigger identifiers are embedded in the broadcast stream, while comprehensive trigger parameters are stored in externally accessible TPT files. This segmentation allows the broadcast to carry minimal trigger signals while the full trigger definitions are retrieved from external sources, resolving the data capacity constraint.
Solution Approach 2:
The patent moves trigger data from a single dimension (broadcast channel) to multiple dimensions by storing detailed trigger parameters in externally accessible files that can be retrieved via network or local storage. This dimensional expansion allows comprehensive trigger data to be available without consuming broadcast channel capacity.
2Reliability
If trigger data is embedded directly in the broadcast stream to ensure immediate processing, then the reliability of trigger execution is improved, but the amount of broadcast data required increases beyond available capacity
Solution Approach 1:
The patent performs preliminary action by pre-generating TPT files containing comprehensive trigger parameters and making them available in external storage locations before the actual trigger execution. The broadcast stream only needs to carry compact trigger identifiers that reference these pre-prepared TPT files, ensuring reliable execution without requiring full trigger data in the broadcast.
Solution Approach 2:
The patent introduces TPT files as an intermediary between the broadcast trigger signals and the trigger execution engine. These intermediary files contain the detailed trigger parameters that bridge the compact broadcast identifiers and the comprehensive trigger processing requirements, enabling reliable execution with minimal broadcast data.
3Measurement precision
If comprehensive trigger parameters are included in every trigger signal to ensure complete event processing, then the accuracy of trigger execution is improved, but the complexity of the broadcast data structure increases
Solution Approach 1:
The patent uses copying by placing comprehensive trigger parameter definitions in external TPT files that can be referenced multiple times by compact trigger identifiers in the broadcast stream. Instead of copying full trigger data into each broadcast signal, the system copies only minimal identifiers, while the complete trigger definitions are shared from the external TPT files, reducing broadcast data structure complexity while maintaining execution accuracy.
