Mobile Device Control for Internet TV with Supplemental Information Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Internet TV systems lack the ability to provide enhanced functionality such as remote control and additional information retrieval without disrupting the viewer's experience, as conventional remote controls cannot offer features like social sharing or browsing metadata.
Innovation Solution
An audio video display device (AVDD) with a processor that enables wireless control from mobile devices, allowing users to browse supplemental information and share content links without disturbing the main display, while ensuring secure device authentication and transparent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional remote control is used to control Internet TV, then basic control functions are provided, but enhanced functionality such as social sharing and metadata browsing cannot be provided
Solution Approach 1:
The mobile device is configured to perform multiple functions: it serves as both a remote control for basic TV control operations and as an enhanced interface for social sharing, metadata browsing, and content recommendations. This multi-functionality resolves the contradiction by allowing a single device to provide both basic control and enhanced features without requiring separate specialized devices.
Solution Approach 2:
The system introduces a server as an intermediary between the mobile device and the Internet TV. The server handles complex operations such as content recommendation generation, social network integration, and metadata aggregation, allowing the mobile device to provide enhanced functionality while keeping its own complexity manageable by delegating heavy processing to the intermediary server.
2Loss of information
If the mobile device browses supplemental information, then enhanced information is provided to the user, but the viewing experience on the main display may be disturbed
Solution Approach 1:
The information display is segmented between two separate devices: the Internet TV maintains the primary video playback display, while the mobile device displays supplemental information such as metadata, recommendations, and social sharing options. This segmentation allows users to access enhanced information without the mobile device's display interfering with the main viewing experience on the TV.
Solution Approach 2:
The system uses the mobile device as an intermediary that retrieves and displays supplemental information separately from the main playback device. This intermediary approach allows information browsing to occur in parallel without causing visual interference or distraction from the primary content being displayed on the Internet TV.
3Ease of operation
If wireless control from mobile devices is enabled, then user convenience is improved, but security risks from unauthorized control may increase
Solution Approach 1:
The system implements a feedback mechanism where the Internet TV actively responds to discovery signals from mobile devices. When a mobile device sends a discovery signal, the TV checks authorization credentials and either responds with authentication information or remains silent. This feedback loop ensures that only authorized devices can establish control, maintaining security while allowing convenient wireless access for approved users.
Solution Approach 2:
The system employs preliminary anti-action by having the Internet TV proactively prevent unauthorized control attempts before they can succeed. The TV monitors for discovery signals and uses its response behavior (responding only to authorized devices or remaining hidden from unauthorized ones) to block potential security threats in advance, thus maintaining security while preserving ease of operation for legitimate users.

AI summary
The user of an Internet TV device can control the Internet TV device using a mobile device such as a smart phone. The smart phone also obtains program information from the Internet TV device and sends the information to a server as a search term, presenting supplemental program information received from the server on the display of the mobile device so that a person can browse the supplemental information without disturbing viewers of the Internet TV device. The mobile device can also grab a link related to the program from the Internet TV device and use that link as a recommendation to friends on social networking sites.
