Remote User Interface Format Adaptation via Transmission Options
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote user interface (RUI) technologies for home networks, such as DLNA-based systems, face challenges in providing a unified interface for various devices, particularly in handling video format preferences, leading to issues where users may not receive RUI if the video format does not match their preferred format, resulting in incomplete service delivery.
Innovation Solution
A method and apparatus that allow a client device to request a remote user interface (RUI) from a server, including preference format information and transmission option information, enabling selective transmission based on preferred formats, allowing users to receive RUI even if the video format does not match their second preference, by setting transmission options to ignore format mismatches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system strictly compares video format with client device preferences, then format compatibility is ensured, but service delivery is blocked when formats do not match
Solution Approach 1:
The patent applies dynamics by making the format comparison process adaptable based on transmission option information. The system dynamically adjusts its behavior: when strict format matching is required, it performs comprehensive comparison; when flexibility is needed, it relaxes format requirements. This resolves the contradiction by allowing the system to switch between strict compatibility checking and flexible service delivery based on real-time conditions.
Solution Approach 2:
The patent changes the parameter of format comparison strictness based on transmission option information. By introducing a configurable parameter (transmission option) that controls whether second preference format information is considered, the system can adjust its format matching behavior. This allows the system to maintain format compatibility when needed while enabling service delivery when format flexibility is acceptable.
2Measurement precision
If the system performs comprehensive format comparison including video format, then format precision is improved, but transmission flexibility is reduced
Solution Approach 1:
The system dynamically adjusts the scope of format comparison based on transmission option information. When adaptability is needed, it performs only first preference format comparison; when precision is prioritized, it performs comprehensive comparison including video format. This dynamic adjustment resolves the contradiction between measurement precision and adaptability.
Solution Approach 2:
The patent segments the format comparison process into two distinct levels: first preference format comparison (always performed) and second preference format comparison (conditionally performed based on transmission option information). This segmentation allows the system to maintain flexibility while preserving the option for precise matching when required.
3Reliability
If the system requires exact format match for RUI transmission, then service quality is maintained, but user accessibility is reduced
Solution Approach 1:
The patent introduces transmission option information as a controllable parameter that adjusts the strictness of format matching requirements. By changing this parameter, the system can switch between maintaining strict service quality (exact format match) and improving user accessibility (flexible format matching). This resolves the contradiction by allowing both modes to coexist based on system state and user needs.

AI summary
A method of providing a remote user interface (RUI) includes receiving a RUI request including first preference format information, second preference format information, and transmission option information, the first preference format information being related to a format preferred by a client device with respect to the RUI, the second preference format information being related to a format preferred by the client device with respect to a video included in the RUI, and the transmission option information indicating whether to consider the second preference format information when transmission of the RUI is decided; comparing a format of the RUI with only the first preference format information, or comparing the format of the RUI and the format of the video comprised in the RUI with the first preference format information and the second preference format information, respectively, based on the transmission option information; and selectively transmitting the RUI to the client.
