Convergence Platform Cross-Device Media Resumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media convergence platforms face challenges in managing content consumption across disparate devices, particularly in authenticating and authorizing users across multiple devices and locations, and in efficiently delivering media streams with varying quality and rights management.
Innovation Solution
A convergence platform that separates user authorization and device authentication, uses fragmented MPEG-4 file delivery to enable seamless playback across devices, and employs DRM technology to manage content rights, allowing users to resume playback on different devices with appropriate quality and resolution based on their subscriptions and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional media platforms are used, then content can be delivered to specific devices, but managing content consumption across multiple devices and locations becomes difficult
Solution Approach 1:
The system segments media content into discrete items with individual rights management, allowing each content item to be independently authorized across different devices. This segmentation enables flexible cross-device consumption while simplifying management through centralized rights assignment rather than device-specific configuration.
Solution Approach 2:
The convergence platform provides universal access to media content across multiple device types (televisions, computers, mobile devices) through a unified system. The platform handles authentication, authorization, and content delivery for all devices through a single interface, eliminating the need for separate management systems for each device.
2Reliability
If device-specific authentication is used, then security is maintained, but user experience is degraded when switching between devices
Solution Approach 1:
The system merges user authentication with device registration into a unified convergence platform. Users authenticate once and gain access across multiple registered devices without repeated authentication steps. The platform combines security mechanisms with seamless user experience by maintaining session state across devices while enforcing rights management.
Solution Approach 2:
The convergence platform acts as an intermediary between users and content delivery systems. It manages authentication and authorization centrally, providing secure access to content across devices without requiring device-specific security procedures. The intermediary handles the complexity of rights management while presenting a simple, consistent interface to users.
3Productivity
If media streams are delivered continuously, then playback is smooth, but quality adaptation and rights management become inefficient
Solution Approach 1:
The system dynamically adjusts media delivery based on device capabilities, network conditions, and user authorization rights. Quality adaptation occurs in real-time according to device specifications and subscription levels. Rights management is dynamically enforced through the convergence platform, allowing flexible content access control without disrupting continuous playback.
Solution Approach 2:
The platform changes delivery parameters (quality, resolution, bitrate) based on device capabilities and user rights. Different content items can be delivered at different quality levels according to subscription plans and device specifications. Rights management parameters are adjusted dynamically to control access without affecting the continuity and efficiency of media delivery.

AI summary
Device capabilities, media rights, and content are managed using a convergence platform to allow seamless consumption of content across disparate devices. Media content can be paused on one device having a particular set of capabilities and rights and resumed on a different device having another set of capabilities and rights. A user can play media on a mobile device, continue playing the media on a desktop computer, and subsequently move to a large screen television and capabilities and rights are automatically identified to seamlessly provide the most appropriate authorized content. Personalized media content information can be provided based on maintained information for user playback stoppage events and the user can resume playback of any number of media streams.
