Mobile Terminal Viewing Reservation Sharing via External Server
Solution Overview
Problem
Users face inconvenience in sharing viewing reservations for specific programs across different mobile terminals, limiting group viewing experiences.
Innovation Solution
A mobile terminal system that connects with external display devices and other mobile terminals, allowing for the sharing of viewing reservations through electronic program guide data and identification information, enabling group viewing reservations and notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If viewing reservation is set through preset application in mobile terminal, then the display device can be controlled, but the viewing reservation cannot be shared with another mobile terminal
Solution Approach 1:
The patent introduces an external server as an intermediary to facilitate viewing reservation sharing between mobile terminals and display devices. The server receives viewing reservation information from one mobile terminal, stores it, and enables other mobile terminals to access and share this reservation information, thus solving the inability to share reservations without direct device-to-device communication complexity
Solution Approach 2:
The patent makes the viewing reservation system universal by enabling multiple mobile terminals to access and share reservations with a single display device through a common platform. The display device itself becomes multi-functional by supporting both direct control and shared reservation functionality from multiple sources
2Ease of operation
If viewing reservation information is transmitted to external mobile terminal, then group viewing experience is enhanced, but communication and coordination complexity increases
Solution Approach 1:
The external server acts as a mediator that handles the complex communication tasks of transmitting viewing reservation information between multiple mobile terminals and the display device. This intermediary approach simplifies the user experience while managing the underlying communication complexity centrally on the server side
3Adaptability or versatility
If identification information of external mobile terminal is displayed, then user can select target device for sharing, but interface complexity increases
Solution Approach 1:
The patent extracts the device selection functionality into a separate, simplified interface element that displays only the necessary identification information of external mobile terminals. This extraction approach presents only the essential selection options to users without exposing the full complexity of the underlying system architecture
