Content-Aware Application Execution via Signature Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the US, there is no established method to execute applications in conjunction with TV programs or arbitrary content viewed through CATV or IPTV, as data broadcasting is not supported in TV broadcasting signals, and existing solutions do not allow for user-specific applications to be executed during content reproduction.
Innovation Solution
A system comprising a receiving apparatus that extracts signature data from content, generates user profile data, and transmits queries to a transmitting apparatus to identify and execute suitable applications based on user profiles, using a database to match content features with user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data broadcasting is used to transmit application commands in TV broadcasting signals, then applications can be executed during program viewing, but this method is not available in the US where TV broadcasting signals do not include data broadcasting bands
Solution Approach 1:
The patent introduces an intermediary system consisting of a transmitter and receiver that operate over communication networks (such as the Internet) to bridge the gap between content delivery and application execution. Instead of relying on the absence of data broadcasting in TV signals, the system uses a separate communication channel to transmit application commands and data between the content source and the user's terminal device, enabling application execution without modifying the TV broadcasting signal structure.
2Adaptability or versatility
If CATV or IPTV is used to deliver content, then more users can access content, but application data may not be transmitted to the receiving apparatus
Solution Approach 1:
The patent segments the content delivery system into separate functional components: content delivery (video/audio signals) and application delivery (data signals). The content is delivered through CATV or IPTV infrastructure, while application commands and data are delivered through a separate communication network channel. This segmentation ensures that the reliability of application data transmission is independent of the content delivery mechanism, allowing applications to be reliably transmitted even when using CATV or IPTV for content delivery.
3Adaptability or versatility
If user profile data is generated and matched with content signature data, then user-specific applications can be executed, but this requires complex query processing and database matching
Solution Approach 1:
The patent implements preliminary action by pre-generating and storing user profile data in a database before actual content viewing occurs. When a user views content, the system extracts signature data from the content and performs a query against the pre-existing user profile database. This approach allows the system to quickly match content with appropriate user profiles and execute relevant applications without performing complex analysis in real-time, thereby reducing the computational burden during content playback.

AI summary
Disclosed herein is a receiving apparatus including: an extracting part configured to extract signature data representing a feature of reproduced content from the content; a profile generating part configured to generate user profile data; a query generating part configured to generate a query containing the signature data and the user profile data, transmit the query thus generated to a transmitting apparatus, and receive a response that is sent back from the transmitting apparatus in accordance with the query and that has been caused to match with the user profile data in the transmitting apparatus; and an application executing part configured to acquire and execute an application in conjunction with reproduction of the content based on the response thus received.
