Portable Digital TV Audience Data Capture via SMS Protocols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for capturing audience data on portable digital TV devices are inefficient, as they rely on conventional mobile data networks and lack real-time data capture capabilities and remote configuration options, with SMS communication methods not fully explored for message building, encapsulation, and reception.
Innovation Solution
A system using SMS Class 2 for sending information from portable devices to servers and SMS Class 0 for receiving configuration messages, employing a binary protocol to minimize traffic and leveraging all device resources for comprehensive audience data analysis, with remote configuration capabilities and software-based architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional mobile data networks are used for data transmission, then data capture capabilities are available, but real-time data transmission and remote configuration are not achieved
Solution Approach 1:
The patent changes the communication parameter from conventional mobile data networks to SMS Class 0 and Class 2 messaging protocols. This parameter change enables both real-time configuration transmission (Class 0) and event data transmission (Class 2), simultaneously achieving fast transmission speed and reliable real-time capture functionality.
2Loss of energy
If SMS communication is used for data transmission, then cost-effective service charging is achieved, but comprehensive audience data analysis is limited
Solution Approach 1:
The patent segments the communication into two distinct SMS types: Class 0 for configuration/commands and Class 2 for event data. This segmentation allows the system to use the cheaper SMS protocol while maintaining comprehensive data collection by dividing the communication protocol into specialized channels that together capture complete audience information.
Solution Approach 2:
The patent embeds multiple data elements (event type, timestamp, device ID, signal quality, location) within the SMS message structure. This nesting allows comprehensive audience data to be transmitted through the compact SMS protocol, maintaining data completeness while using cost-effective messaging.
3Adaptability or versatility
If remote configuration capabilities are added, then service flexibility is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary configuration message (SMS Class 0) that carries configuration parameters from the server to the portable device. This intermediary mechanism enables remote configuration capabilities without requiring complex device-side configuration interfaces, maintaining service flexibility while minimizing device complexity.

AI summary
A system and method for capturing and recording parameters of events on portable devices with a digital television receiver, a method for remote configuration of service parameters for capturing and recording events on portable devices, as well as a portable device and server. More specifically, a system and method for capturing audience data, the method for remote configuration of audience data capture service, especially adapted for digital TV services on portable devices such as mobile phones, smartphones, and personal digital assistants, among others, that helps in remotely setting up the service. Another aspect of the present architecture is the fact that it is completely based on software, using only resources that are already present in portable devices with an embedded service.
