Service Selection Priority for Overlapping Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the capability to selectively output user-corresponding content, such as advertisements, based on user information at the reception apparatus side, particularly when delivery time periods of transmission contents overlap across different channels.
Innovation Solution
A transmission apparatus sets service selection priority information for each content, which is transmitted to the reception apparatus, allowing it to prioritize and cache content based on this information, enabling selective acquisition and output of high-priority content even when delivery times overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reception apparatus receives all transmission contents during overlapping delivery periods, then content availability is improved, but storage space consumption increases and content selection capability deteriorates
Solution Approach 1:
The patent introduces service selection priority information as a new parameter to differentiate and select contents during overlapping delivery periods. The reception apparatus uses this priority parameter to determine which contents to cache, transforming the selection process from random or sequential to priority-based, thereby improving content selection capability while controlling storage space usage.
2Ease of operation
If the reception apparatus caches all contents with equal priority, then content accessibility is improved, but user-targeted content delivery deteriorates
Solution Approach 1:
The patent applies local quality by assigning different service selection priority levels to different contents based on user information and content characteristics. Instead of treating all contents uniformly, the system differentiates content priority locally, enabling user-targeted content delivery while maintaining ease of access for high-priority contents through the cache.
3Device complexity
If the reception apparatus processes contents in transmission order, then processing simplicity is improved, but content delivery efficiency deteriorates during overlapping periods
Solution Approach 1:
The patent changes the processing parameter from transmission order to service selection priority order. The reception apparatus processes contents based on their assigned priority levels rather than arrival sequence, improving content delivery efficiency during overlapping periods. While this increases processing logic complexity slightly, the efficiency gain in content delivery justifies the change.

AI summary
A configuration is implemented by which, in a case where delivery time periods of transmission contents through different channels overlap with each other, a reception apparatus can select an acquisition target on the basis of priority information. A transmission apparatus sets, for each of transmission contents, service selection priority information (Service Selection Priority) capable of being utilized as a cache process priority criterion in the reception apparatus, and transmits the service selection priority information to the reception apparatus. The service selection priority information is utilized as priority information that makes it possible, in a case where delivery time periods of transmission contents through different channels overlap with each other, for the reception apparatus to select a content having a high value of the service selection priority information as a cache target.
