Satellite Content Caching With DRM-Guided Offline Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of broadcast and streamed content systems often miss out on programming due to limited live listening times and digital rights management restrictions, preventing recording of desired content.
Innovation Solution
Implementing a Content Caching Service (CCS) that allows users to download and store audio and other content for later playback, using metadata for selection and compliance with DRM, and optimizing for large-scale content delivery over extended periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users rely on live broadcast listening, then they can access content in real-time, but they miss programming outside their limited listening hours
Solution Approach 1:
The system performs preliminary actions by downloading and caching content from broadcasts before the user needs to access it. The receiver automatically or semi-automatically retrieves programming during off-peak times and stores it locally, making content available for playback at any convenient time without requiring live listening.
Solution Approach 2:
The system creates local copies of broadcast content that can be stored and replayed multiple times. Instead of requiring users to listen to the original live broadcast, the receiver makes copies of the content and stores them in local memory or storage devices, allowing users to access identical content on-demand without occupying broadcast resources.
2Ease of operation
If recording of programs is enabled, then users can access content at convenient times, but digital rights management restrictions prevent recording
Solution Approach 1:
The system introduces an intermediary mechanism between the broadcast content and the user's recording capability. Rather than direct recording which would violate DRM, the receiver uses authorized caching services that act as intermediaries - the content is downloaded and stored through licensed channels with proper authentication and rights management verification built into the process.
Solution Approach 2:
The system changes the operational parameters of content storage by transitioning from prohibited recording to authorized caching. This involves changing the legal and technical parameters of content retention - using broadcast encryption, authentication protocols, and licensed storage methods that transform the act of saving content from a DRM violation into a compliant operation.
3Adaptability or versatility
If users manually select content to download, then they can choose specific programs, but they cannot discover content outside their regular channels
Solution Approach 1:
The system implements feedback mechanisms that analyze user listening habits, preferences, and behavior patterns to automatically recommend and cache content. The receiver monitors what users watch, when they watch it, and their preferences, then uses this feedback to automatically select and download additional content that aligns with user interests, reducing the need for manual selection while maintaining personalization.
Solution Approach 2:
The system enables self-service by allowing the receiver to automatically manage content selection and caching without requiring constant user intervention. The device serves itself by autonomously deciding what content to download based on available broadcast data, user profiles, and storage capacity, while still allowing users to override or adjust selections when desired.
4Quantity of substance
If large amounts of content are cached, then users have more content available, but storage capacity and download time become limiting factors
Solution Approach 1:
The system employs periodic action by scheduling content downloads during off-peak broadcast times or when the receiver is not actively being used. Instead of downloading all content simultaneously, the receiver periodically retrieves content in manageable chunks during idle periods, distributing the download burden over time while ensuring content is available when needed.
Solution Approach 2:
The system segments the content download process into smaller, manageable portions rather than attempting to download entire programs at once. Content is divided into segments or episodes that can be downloaded incrementally, allowing the receiver to maximize storage utilization while managing download time requirements through parallel or sequential segment retrieval.

AI summary
Systems and methods are presented to facilitate caching of programming from broadcast and/or content streaming services to a user device for local playback. In addition, metadata can be provided to guide the user in selecting, caching, or playing the cachable content. In some exemplary embodiments, a receiver or other user device can automatically select the programming to be cached based on a user's historical topic interest and listening history. In some exemplary embodiments, the metadata can also include DRM information that can limit the ability of a user to playback the content, so as to comply, if necessary, with operative legal requirements related to usage of the content.
