Dual-Screen IDTV Remote Console via Abstract UI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen interactive digital television (IDTV) systems face challenges due to context diversity among handheld devices, such as varying screen sizes and input interfaces, and the lack of standard authoring tools, making it difficult to develop content that can seamlessly interact across different devices.
Innovation Solution
The implementation of modality-independent remote console technology using the AIAP-URC standard, which provides an abstract user interface description in XML, allowing for the translation of this interface into a physical user interface tailored to each device's context, enabling unified control across different handheld devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dual-screen IDTV system is implemented to allow multiple viewers to operate IDTV contents simultaneously, then the ease of operation and user interaction are improved, but the device complexity increases due to the need to support multiple handheld devices with different contexts
Solution Approach 1:
The patent introduces an abstract user interface description as an intermediary layer between the IDTV content and multiple handheld devices. This abstract description serves as a mediator that translates diverse device-specific interfaces into a unified control mechanism, allowing multiple users to interact with the IDTV content without directly managing the complexity of each device's unique interface
Solution Approach 2:
The patent creates a universal remote control mechanism that can function across multiple different handheld devices. The abstract user interface description enables a single control system to universally operate IDTV content regardless of the specific device type, screen size, or input interface, thereby improving ease of operation without proportionally increasing system complexity
2Ease of manufacture
If standard authoring tools are developed for dual-screen IDTV, then the ease of manufacture and content production are improved, but the device complexity and standardization requirements increase
Solution Approach 1:
The patent incorporates the abstract user interface description into the IDTV content during the authoring phase, before the content is distributed to multiple devices. This preliminary action embeds the adaptive interface logic directly into the content creation process, eliminating the need for complex post-production adaptation tools and simplifying the manufacturing process
Solution Approach 2:
The patent uses the abstract user interface description as a template or copy that can be replicated across multiple devices without modification. This abstract description serves as a master copy that automatically adapts to different device contexts, reducing the need for creating and maintaining multiple device-specific versions of the same content
3Adaptability or versatility
If adaptive user interface technology is implemented to handle context diversity of handheld devices, then the adaptability and versatility are improved, but the device complexity increases due to the need for context-aware processing
Solution Approach 1:
The patent applies local quality by generating device-specific interface instances from the abstract user interface description based on each handheld device's specific context (screen size, input interface, capabilities). Each device receives a customized interface version tailored to its local characteristics, improving adaptability without requiring the entire system to be complex

AI summary
Disclosed is a system and method of dual-screen interactive digital television (IDTV), which is implemented by applying modality-independent remote console technology. The system has two ends, referred to as host IDTV and handheld device. The host IDTV includes a host IDTV content, an IDTV middleware, a host graphic user interface (host GUI), and a server-side remote console control protocol. The handheld device includes a handheld IDTV content, an interface generator, a handheld GUI, and a client-side remote console control protocol. In the invention, the DTV content may only have a dual-screen execution mode. The DTV content may also switch between single-screen and dual-screen modes.
