Remote DTT Service Configuration via Frequency Map Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital television systems for receiving DTT signals lack optimization in service reception, requiring user-initiated service list installation and frequency scanning, which can be time-consuming and inconvenient, especially when transmitter changes occur.
Innovation Solution
A remote management method that allows a configuration server to remotely manage digital terrestrial television parameters, including frequency maps and service associations, using the TR-069 CWMP protocol to automate the installation and configuration of DTT services in video devices, reducing the need for user intervention and improving installation speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a video device scans all frequencies to install DTT services, then complete service coverage is achieved, but installation time increases significantly
Solution Approach 1:
The server performs preliminary actions by pre-processing frequency information, identifying DTT signal locations, and preparing optimized frequency maps before the video device needs installation. This allows the device to receive ready-to-use configuration data rather than scanning all frequencies from scratch.
Solution Approach 2:
A server acts as an intermediary between the frequency database and the video device. The server retrieves frequency information, processes it to identify DTT signals, and delivers optimized results to the device, eliminating the need for the device to perform time-consuming full frequency scans.
2Ease of operation
If DTT service configuration is automated through remote management, then user effort is reduced, but system complexity increases
Solution Approach 1:
The video device performs self-service by automatically receiving and applying frequency map configurations from the server without requiring user intervention. The device autonomously configures its DTT service parameters based on remote instructions, eliminating manual setup efforts.
Solution Approach 2:
The server serves as an intermediary that manages the complexity of frequency configuration and service setup, handling all processing, optimization, and delivery of configuration data, thereby shielding the user from system complexity while enabling automated configuration.
3Productivity
If frequency maps are pre-processed and transmitted by a server, then installation speed improves, but server processing requirements increase
Solution Approach 1:
The server performs preliminary processing of frequency maps in advance, identifying DTT signal locations and preparing optimized configuration data before installation is needed. This upfront processing enables fast device installation while distributing the computational burden over time rather than requiring intensive real-time processing.
Solution Approach 2:
The server extracts only the essential DTT frequency information from complete frequency databases, delivering minimal necessary data to devices. This extraction approach reduces the amount of data processed and transmitted, lowering server energy requirements while maintaining installation speed benefits.

AI summary
The invention relates to the remote management of a digital terrestrial television device (23). In order to improve the terrestrial television reception, a control command is transmitted by a distant remote management server (20) through another communication channel, the control command requesting the video device to set at least a digital terrestrial television parameter related to a service list management.
