Broadcasting Service Apparatus Synchronizing Multiple Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing demand for synchronizing multiple devices used by a single user to provide enhanced content services, particularly in the context of IPTV, where users want to access additional information related to broadcast programs across various connected devices.
Innovation Solution
A method and apparatus for interworking and synchronizing multiple devices by generating and transmitting interworking information between them, allowing for coordinated display and control of content across devices such as set-top boxes and mobile devices, enabling users to select and view content on one device while receiving additional information on another.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are connected to provide enhanced content services, then user experience and service versatility are improved, but device complexity and synchronization difficulty increase
Solution Approach 1:
The broadcasting service apparatus serves multiple devices simultaneously with different functions - providing broadcast content to first device, additional information to second device, and enabling interworking between devices. This multi-functional approach allows one apparatus to handle diverse service requirements without proportionally increasing complexity
Solution Approach 2:
The broadcasting service apparatus acts as an intermediary that generates interworking information and transmits it to multiple devices. This mediator role coordinates synchronization and data distribution centrally, avoiding the complexity of direct peer-to-peer device coordination
2Reliability
If interworking information is transmitted between multiple devices, then synchronization capability is improved, but communication overhead and system complexity increase
Solution Approach 1:
The interworking information is extracted and generated by the broadcasting service apparatus as a separate entity, then transmitted to relevant devices. This extraction approach centralizes the synchronization logic in one location rather than distributing complex synchronization protocols across all devices
Solution Approach 2:
The broadcasting service apparatus generates copies of interworking information and transmits them to multiple devices that need synchronization. This copying mechanism allows reliable synchronization without requiring complex real-time negotiation or acknowledgment protocols between devices

AI summary
A method of synchronizing multiple devices with each other is provided. The method includes generating first interworking information corresponding to a first device, transmitting the generated first interworking information to the first device, receiving second interworking information from a second device and if the first interworking information corresponds to the second interworking information, synchronizing the first device with the second device, wherein the second device is configured to display broadcasting related information generated based on a broadcasting schedule provided by a broadcasting transmission apparatus that transmits broadcasting contents to the first device.
