Video Co-Watching Synchronization via Playback Modifier Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital communication systems are inefficient, inflexible, and insecure, particularly in handling digital content sharing during group video chats, as they require excessive user interactions, are limited in content control, and compromise data privacy by tracking user information.
Innovation Solution
A video co-watching system that synchronizes digital video content across multiple devices during live video chats by using a playback modifier signal, allowing independent playback control and encryption to enhance security and privacy, integrating digital media players for seamless content sharing without central monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems track and obtain large amounts of device data to determine user preferences and generate recommendations, then personalization and recommendation accuracy are improved, but data privacy and security are compromised
Solution Approach 1:
The patent introduces an encrypted content identifier as an intermediary between the user's viewing behavior and the system's recommendation engine. Instead of directly tracking and storing detailed user data, the system uses encrypted identifiers that allow for personalized recommendations without exposing raw user information, thus resolving the contradiction between measurement precision and data privacy
Solution Approach 2:
The system creates encrypted copies of content identifiers rather than storing actual user viewing data. These encrypted copies preserve the ability to generate recommendations while eliminating the security risks associated with storing sensitive user information, addressing the contradiction between personalization accuracy and data security
2Object-affected harmful factors
If conventional systems require users to navigate through many layers of user interfaces to access desired data and functionality, then data security is maintained through controlled access, but ease of operation deteriorates
Solution Approach 1:
The patent merges the content sharing functionality and video chat functionality into a single integrated interface. Users can share digital content and communicate via video chat simultaneously without needing to navigate between multiple applications or interface layers, thus improving ease of operation while maintaining security through the encrypted identifier system
Solution Approach 2:
The system provides a universal interface that handles multiple functions (content sharing, video chat, playback control) within a single application. This multi-functional approach eliminates the need for users to switch between applications or navigate complex interface hierarchies, resolving the contradiction between security control and operational simplicity
3Object-affected harmful factors
If conventional systems require separate applications for sharing digital content during video chat, then data security is maintained through application isolation, but device complexity and ease of operation worsen
Solution Approach 1:
The patent combines content sharing and video chat capabilities into a single integrated application. This eliminates the need for users to switch between separate applications (such as a messaging app and a video chat app), reducing device complexity and improving ease of operation while maintaining security through the encrypted identifier architecture
Solution Approach 2:
The system creates a universal platform that performs multiple functions (video conferencing, content sharing, synchronized playback) within one application. This multi-functional design reduces the overall number of applications needed on user devices, addressing the contradiction between security isolation and system complexity
4Device complexity
If conventional systems limit content controls within group video chat, then system complexity is reduced, but adaptability and ease of operation deteriorate
Solution Approach 1:
The encrypted content identifier acts as a mediator that enables flexible playback controls without increasing system complexity. The identifier allows the system to synchronize playback across multiple devices and respond to user interactions (such as pausing or seeking) while maintaining a relatively simple underlying architecture, thus resolving the contradiction between complexity and adaptability

AI summary
This disclosure describes a video co-watching system that can efficiently, flexibly, and securely provide access to, and synchronize, co-watching digital video content across multiple participant devices while providing live digital video chat streams between the participant devices. For example, the video co-watching system can enable the participant devices to simultaneously present co-watching digital video content together with a presentation of a video chat. In addition, the video co-watching system can synchronize the co-watching digital video content at each participant device while also facilitating video chatting between the participant devices by transmitting a playback modifier signal to cause one participant device to perform a modification to the playback made at another participant device.
