ACR Receiving Device for Hybrid Broadcasting Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a technical solution for providing application programs in conjunction with digital television shows using the Automatic Content Recognition (ACR) technique, which is essential for realizing hybrid broadcasting and communication services, especially when terrestrial broadcasting is not directly received but through CATV or satellite networks.
Innovation Solution
A receiving device equipped with a feature extractor, identification result acquirer, command acquirer, and controller that uses ACR to identify digital television content and control the operation of application programs, including activation, registration, and timing-based commands, allowing for the provision of application programs synchronized with digital television shows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ACR technique is used to identify digital television content and provide application programs, then hybrid broadcasting and communication services can be realized, but currently no technical system exists for providing application programs using ACR technique
Solution Approach 1:
The system is divided into distinct functional modules: ACR processing unit for content identification, application program management unit for handling application programs, and command execution unit for controlling application operations. This segmentation allows each module to perform its specific function independently, reducing overall system complexity while enabling hybrid services.
Solution Approach 2:
The receiving device is designed to perform multiple functions: receiving digital television broadcasts, processing ACR identification, managing application programs, and executing commands. This multi-functionality allows a single device to provide hybrid broadcasting and communication services without requiring separate dedicated systems.
2Adaptability or versatility
If application programs are provided through CATV or satellite networks instead of direct terrestrial broadcasting, then service coverage is extended, but facilities and dedicated terminals must be renewed
Solution Approach 1:
The receiving device is designed with universal compatibility to work with multiple network types including CATV and satellite networks in addition to direct terrestrial broadcasting. This multi-functionality extends service coverage across different network infrastructures without requiring dedicated terminals for each network type.
Solution Approach 2:
The system dynamically adapts to different network environments by adjusting its reception and processing methods based on the input source. This dynamic capability allows the same facility to serve multiple network types without requiring physical renewal or dedicated hardware for each network.
3Ease of operation
If application programs are activated in synchronization with AV content progression, then user experience is enhanced, but precise timing control is required
Solution Approach 1:
The system continuously monitors the progression of AV content and uses this feedback to trigger application program execution at precise moments. The ACR processing unit provides real-time content identification feedback that enables the command execution unit to activate applications in synchronization with specific content events, enhancing user experience while maintaining timing accuracy.
Solution Approach 2:
Application programs are prepared and loaded in advance before their scheduled execution time. The system pre-processes and readies applications based on anticipated content progression, so that when the trigger moment arrives, the application can be activated immediately with precise timing without delays.
Data Source
AI summary
A receiving device is provided that includes circuitry configured to receive audio video content and extract a feature from either one or both of a video signal and an audio signal of the received audio video content. The circuitry is configured to send the extracted feature to a feature identification server and receive, from the feature identification server, a response including location information and time position information. The circuitry is configured to generate a request based on the location information and the time position information, and send the request to a server associated with the location information. Further, the circuitry is configured to receive data broadcasting information from the server and control a display in accordance with the data broadcasting information.
