CM Substitute Storage Management for Broadcast Signal Receiving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast signal receiving apparatuses struggle to display addressable commercial messages (CMs) that are consistently matched with the content of the broadcast program, often resulting in CMs being inconsistent with the program content, which can lead to viewer dissatisfaction.
Innovation Solution
The apparatus includes a receiving element, a CM substitute time period information acquisition element, a CM storage memory, and a control element that monitors the remaining capacity to prioritize and store CM substitutes, ensuring they are played during specific assigned times and matched with the broadcast content based on viewer preferences, with the ability to notify an external server for further CMs when storage capacity is limited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CM substitutes are stored to provide more options for viewers, then the variety and personalization of CM display is improved, but the storage capacity requirement increases
Solution Approach 1:
The patent changes the parameter of storage management by introducing priority levels for different CM substitutes. Instead of treating all CMs equally, the system assigns priorities based on viewer preferences and program relevance, allowing efficient utilization of limited storage capacity while maintaining high adaptability in CM selection
Solution Approach 2:
The patent extracts and prioritizes only the most relevant CM substitutes for storage based on viewer preferences and program content matching. By selectively storing only high-priority CMs rather than all possible CMs, the system achieves good personalization效果 with limited storage capacity
2Measurement precision
If CM substitutes are pre-stored in large quantities, then the selection accuracy for matching viewer preferences is improved, but the device complexity and storage management burden increase
Solution Approach 1:
The patent performs preliminary action by pre-calculating and assigning priorities to CM substitutes based on stored viewer preference data before actual CM selection occurs. This preliminary prioritization simplifies the real-time selection process while maintaining high matching accuracy
Solution Approach 2:
The system implements self-service by automatically managing CM priority assignments and selections based on stored preference data without requiring complex external intervention. The control element autonomously monitors storage capacity and manages CM substitution decisions
3Reliability
If the system monitors and manages storage capacity dynamically, then the CM substitute selection relevance to broadcast content is improved, but the control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the control element continuously monitors storage capacity and adjusts CM selection strategies accordingly. This feedback loop ensures that CM substitutes remain relevant to broadcast content while adapting to changing storage conditions without requiring overly complex control systems

AI summary
Provided are a broadcast signal receiving apparatus and a broadcast signal receiving method, capable of providing CMs to make the CMs have greater similarity to viewing program content. The broadcast signal receiving apparatus of the present embodiment comprises: a receiving element used for receiving and demodulating broadcast content; a CM substitute time period information acquisition element used for acquiring a specific assigned time period for a CM substitute among one or more CM during the playing of the broadcast content; a CM substitute acquisition element used for acquiring at least one CM substitute associated with the broadcast content from external device; and a CM selection element used for playing the CM substitute during a specific assigned time period for the CM substitute on the basis of the time period information for the CM substitute.
