ID-Mapped Subsidiary Content Receiving for Family Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to personalize subsidiary content delivery in response to individual user preferences within a family setting, leading to difficulty in viewing both main and subsidiary content simultaneously on a typical receiving terminal unit.
Innovation Solution
A system comprising a main receiving terminal unit and multiple subsidiary receiving terminal units, each with specific ID information, allows personalized transmission of subsidiary content based on user taste, enabling individual viewing of desired content on portable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If main content and subsidiary content are simultaneously displayed on a television receiver, then both contents can be provided to users, but each display area becomes narrower making it difficult for users to view each content
Solution Approach 1:
The patent divides the content delivery system into a main receiving terminal unit for main content and multiple subsidiary receiving terminal units for subsidiary content. This segmentation allows each type of content to be displayed on appropriately sized screens, with the main content on the large television and subsidiary content on portable devices, thereby maintaining full content information while improving viewing convenience.
Solution Approach 2:
The patent introduces subsidiary receiving terminal units as intermediaries between the content distribution system and individual users. These portable devices receive and display subsidiary content separately from the main television, acting as mediators that enable users to access subsidiary content without competing for display space on the main television screen.
2Ease of operation
If subsidiary content is displayed on portable communication equipment and remote control units, then viewing convenience is improved, but personalization of subsidiary content according to individual family members' tastes cannot be achieved
Solution Approach 1:
The patent applies local quality by assigning specific ID information to each subsidiary receiving terminal unit and configuring the system to provide different subsidiary content to different terminals based on their ID information. This enables the system to recognize individual users and deliver personalized content (such as different commercial information or data broadcasts) to each family member's portable device according to their specific preferences.
3Device complexity
If a typical receiving terminal unit is used for both main and subsidiary content, then device simplicity is maintained, but display area for each content becomes narrower
Solution Approach 1:
The patent segments the receiving terminal units into main and subsidiary types with different display characteristics. The main receiving terminal unit (television) provides large display area for main content, while subsidiary receiving terminal units (portable devices) provide appropriate display area for subsidiary content. This segmentation resolves the contradiction by matching display area to content type rather than forcing all content onto a single device.
Data Source
AI summary
A method of reproducing audio content between a main terminal including a first speaker and a plurality of subsidiary terminals including a second speaker. Device specific identification (ID) information of the subsidiary terminals and association information for transmitting one of the audio data of the audio content to one of the subsidiary terminals are stored. The association information defines that one of the audio data of the audio content is associated with one of the device specific ID information. The subsidiary terminals transmit/receive with the main terminal and the device specific ID information is transmitted from the subsidiary terminals to the main terminal when connecting to the main terminal. The encoded audio data of the audio content is transmitted to the subsidiary terminals based on the association information, then is decoded and the subsidiary terminals output the audio data to the second speaker.
