Personalized FAST Service List Generation via DVB-I Parameter Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia data delivery systems for Free Ad-Supported Streaming Television (FAST) services lack the ability to provide personalized content distribution efficiently, especially in frameworks like DVB-I, where user-specific and group-specific services are not adequately supported.
Innovation Solution
A computer-implemented method and apparatus that allow for personalized multimedia data delivery by generating and transmitting customized service lists to user devices based on user-specific or group-specific parameters, using a DVB-I framework to manage and signal personalized FAST channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional broadcast TV delivery systems are used, then content distribution is simple and straightforward, but personalization and user-specific service support are lacking
Solution Approach 1:
The service list is segmented into multiple types (default service list and custom service list) that can be independently managed and delivered. The system divides the service delivery process into separate components: service list generation, customization based on user parameters, and targeted delivery to specific user devices, allowing personalization without overwhelming system complexity
Solution Approach 2:
The system performs preliminary actions by pre-generating default service lists and pre-configuring customization parameters before actual content delivery. User profiles and service preferences are established in advance, enabling rapid personalized service delivery without real-time complex processing
2Ease of operation
If personalized service lists are generated for each user, then user experience is improved, but data processing and transmission overhead increases
Solution Approach 1:
The system applies partial action by delivering only the relevant portion of service lists to each user - specifically, the default service list plus customized entries based on user parameters. Rather than transmitting complete service catalogs to all users, the system selectively delivers only necessary personalized information, reducing data processing and transmission time while maintaining improved user experience
Solution Approach 2:
The system changes parameters by using user-specific identifiers and preference parameters to transform generic service lists into personalized versions. By varying the service list content based on user parameters (such as user ID, preferences, and profile data), the system efficiently generates personalized service lists through parameter-driven customization rather than creating entirely new lists for each user
3Reliability
If custom service lists are delivered to user devices, then service relevance is improved, but network bandwidth consumption increases
Solution Approach 1:
The system extracts only the essential and relevant service information from complete service catalogs, delivering minimal necessary data to user devices. By extracting and delivering only customized service entries and key parameters rather than full service lists, the system maintains high service relevance while significantly reducing network bandwidth consumption
Data Source
AI summary
A method for delivering multimedia data to a user device of a multimedia data delivery system is proposed, which includes, at a server device of the multimedia data delivery system, receiving, from the user device, a query message requesting service list data. The query message includes a parameter for querying custom service list data in relation to a user of the user device, and upon receiving the query message, generating a response message for transmission to the user device which includes a list of multimedia services customized for the user based on the parameter.
