Synchronizing E-book and Video Content via Event Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-book technologies lack effective synchronization methods to integrate video content with text-oriented e-book content, limiting the ability to display and search multimedia information in a coordinated manner.
Innovation Solution
A synchronization method and apparatus that connect devices capable of displaying video and e-book content, allowing event information to be transmitted and performed in synchronization using shared synchronization information, enabling coordinated playback and search functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If E-book content is integrated with video content, then the diversity and richness of information is improved, but the complexity of synchronization and coordination between different content types increases
Solution Approach 1:
The patent introduces a synchronization server as an intermediary component that manages the coordination between video content and E-book content. The server receives synchronization information from both content sources, processes it, and distributes coordinated playback instructions to client devices. This mediator approach resolves the technical contradiction by externalizing the synchronization complexity to a dedicated service, allowing the client devices to handle diverse content types without bearing the full burden of coordination complexity.
2Adaptability or versatility
If separate devices are used for video content and E-book content, then the functionality and versatility are improved, but the user interaction and coordination between devices become more complex
Solution Approach 1:
The patent implements a universal synchronization protocol that enables multiple device types (video players, E-book readers, mobile devices) to participate in a coordinated system through a common interface. The synchronization server acts as a universal coordinator that can communicate with various device types using standardized protocols, allowing each device to maintain its specialized functionality while seamlessly integrating into the unified system. This resolves the contradiction by providing a universal communication layer that simplifies user interaction across diverse devices.
3Measurement precision
If synchronization information is maintained between devices, then the coordination accuracy is improved, but the data transmission and management overhead increases
Solution Approach 1:
The patent extracts the heavy lifting of synchronization data management from individual devices and concentrates it in the synchronization server. The server maintains the master synchronization information and only transmits essential coordination instructions to client devices, rather than requiring continuous exchange of detailed synchronization data between all device pairs. This extraction approach maintains high synchronization accuracy while significantly reducing the data transmission overhead at the device level.
Data Source
AI summary
A method of synchronizing a first device capable of displaying video content and including the video content, and a second device capable of displaying E-book content associated with the video content and including the E-book content. The first device is connected to the second device according to a specific protocol. In response to a specific event for the video content or the E-book content occurring in one of the first and second devices, the device in which the specific event occurs generates event information about the specific event and transmits it to the other of the first and second devices, and performs the specific event according to the event information. Upon receiving the event information, the other of the first and second devices performs the specific event according to the received event information in synchronization with the device in which the specific event occurred, using synchronization information between the video content and the E-book content.
