Broadcast Signal Segmentation for Selective Secondary Content Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies are unable to selectively store content other than the primary broadcast signal, which includes both moving images and audio, and secondary content such as news, weather forecasts, and program guides, within a broadcast signal.
Innovation Solution
An information processing apparatus and system that includes reception means to receive a broadcast signal, display control means to display broadcast content, and storage content output means to selectively output storage content different from the broadcast content to storage means, allowing for the identification and storage of secondary content within the broadcast signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broadcast signal includes both broadcast content and storage content, then the information processing apparatus can store secondary content, but existing technologies cannot selectively store only storage content different from broadcast content
Solution Approach 1:
The patent segments the broadcast signal into distinct broadcast content and storage content components. The reception means receives the composite signal, the display control means handles broadcast content separately, and the storage content output means extracts and outputs storage content to storage means. This segmentation enables selective storage of only the desired content while maintaining system manageability.
Solution Approach 2:
The patent applies extraction by separating storage content from the broadcast signal. The storage content output means identifies and extracts storage content that is different from broadcast content, then outputs it to storage means. This extraction mechanism enables selective storage of secondary content without storing the entire broadcast signal.
2Ease of operation
If the apparatus displays broadcast content, then users can view the primary program, but storage content may be overlooked or not stored properly
Solution Approach 1:
The patent introduces an intermediary mechanism through the storage content output means, which acts as a mediator between the broadcast signal and storage means. This intermediary component specifically identifies and extracts storage content while the display control means simultaneously handles broadcast content for display. The intermediary ensures reliable capture of storage content without interfering with the user viewing experience.
3Adaptability or versatility
If the channel is changed during broadcasting, then users can switch programs, but ongoing storage content transmission may be interrupted
Solution Approach 1:
The patent implements feedback through continuous monitoring of the broadcast signal by the reception means. The storage content output means receives feedback about channel changes and adjusts its operation accordingly. When a channel change is detected, the system can resume storage content transmission from the new channel, ensuring continuity despite user-initiated channel switching.

AI summary
Of the types of content included in a broadcast signal, a type of content different from broadcast content is selectively stored. A broadcast signal reception block receives a broadcast signal of a selected channel. A display control block controls such that broadcast content included in the broadcast signal received by the broadcast signal reception block is displayed on a display block. If storage content that is content identified to be stored is included in the broadcast signal received by the broadcast signal reception block, then a storage content output block outputs this storage content to a storage block.
