Digital Television Receiver Regional Rating Table Update Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital television receivers face challenges in decoding and updating regional rating schemes for television programs, as these schemes can differ by region and may be updated, leading to a need for mechanisms to handle new or unfamiliar rating configurations.
Innovation Solution
A method for a digital television receiver to store and manage regional rating table information, including identifying and comparing version and region identifications within broadcast packets, and updating settings accordingly to ensure compatibility with new or updated rating schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the digital television receiver stores and updates regional rating table information from broadcast packets, then the receiver can accurately interpret and apply updated regional rating schemes, but the device complexity increases due to the need for comparing version and region identifications and managing multiple rating configurations
Solution Approach 1:
The patent applies preliminary action by pre-storing a first regional rating table in the digital television receiver before receiving broadcast packets. This allows the receiver to have rating information ready in advance, enabling it to quickly compare and update when new rating tables are received, thus improving reliability without significantly increasing operational complexity.
Solution Approach 2:
The patent uses copying by receiving a second regional rating table from broadcast packets and comparing it with the stored first rating table. The receiver copies only the necessary identification information (version identification and region identification) to determine whether an update is needed, avoiding the need to process and store entire rating tables unnecessarily, thus managing complexity while maintaining accuracy.
2Adaptability or versatility
If the digital television receiver continuously monitors and updates regional rating tables from broadcast packets, then the receiver ensures compatibility with new rating schemes, but the loss of time increases due to the monitoring and comparison processes
Solution Approach 1:
The patent applies extraction by taking out only the critical identification elements (version identification and region identification) from the broadcast packets for comparison with the stored rating table. This selective extraction allows the receiver to determine update necessity quickly without processing the entire rating table content, thus improving adaptability while minimizing time loss.
Solution Approach 2:
The patent uses partial action by performing only the necessary comparison of identification fields rather than fully processing and validating the entire rating table content. This partial approach is sufficient to determine whether an update is needed, achieving adaptability with minimal time investment.
3Adaptability or versatility
If the digital television receiver pre-programs multiple regional rating schemes, then the receiver can handle different regions and updated schemes, but the device complexity increases due to storing multiple rating configurations
Solution Approach 1:
The patent applies universality by designing the digital television receiver to store and process multiple regional rating tables with different region identifications and version identifications. The receiver uses a universal comparison mechanism that works across different rating schemes, allowing it to adapt to various regions and updated schemes without requiring separate management mechanisms for each scheme, thus achieving multi-functionality without excessive complexity.

AI summary
A method performed by a digital television receiver associated with a television includes storing in a memory a first rating configuration, including a region identification of the first rating configuration and a version identification of the first rating configuration, for rating a television program in accordance with a rating scheme, and storing in the memory an identification of a first television channel as a default channel for the rating scheme. The method further includes receiving a subset of a group of transport packets via a receiving channel, comparing the region identification and the version identification of the first and the second rating configurations, and if the region identifications are the same, and the version identifications of the first and the second rating configurations indicate that the second configuration is not newer than the first rating configuration, not storing the second configuration.
