Optical Recording Media for Latency-Free Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable television networks face a competitive disadvantage due to latency in content availability compared to retail and rental outlets, and existing solutions fail to provide timely, high-speed delivery of large data files with secure digital rights management and recording capabilities.
Innovation Solution
The method involves using existing network infrastructure for high-speed data download and recording content onto a tangible medium like DVDs, integrating digital rights management, and allowing users to purchase and record content contemporaneously with its retail or rental release, using consumer premises equipment with recording capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If content is distributed over cable network using conventional VOD infrastructure, then content delivery is achieved, but latency in content availability occurs compared to retail and rental outlets
Solution Approach 1:
The system pre-positions content on optical recording media at customer premises before it is needed, eliminating distribution latency. When a customer wants to purchase content, the content is already locally available on the optical disc, allowing immediate transfer and playback without waiting for network delivery or third-party shipping.
2Ease of operation
If third party providers are used for billing and shipping DVD copies, then content purchase fulfillment is achieved, but protracted and unpredictable delivery period occurs
Solution Approach 1:
The system extracts the content delivery function from third-party providers and implements it locally at customer premises using optical recording media and cable modem infrastructure. This eliminates reliance on external shipping services and their associated delays, allowing immediate content transfer upon purchase.
Solution Approach 2:
The patent introduces optical recording media as an intermediary carrier that bridges the gap between content ownership and physical delivery. The media serves as a tangible voucher that can be instantly transferred and played back, mediating between the purchase transaction and content access without requiring traditional shipping infrastructure.
3Speed
If high-speed data download is used for content delivery, then download speed is improved, but infrastructure complexity increases
Solution Approach 1:
The system creates optical copies of content on DVD-like media that can be stored locally and played back without requiring continuous high-speed network connectivity. The optical media serves as a portable, high-capacity storage medium that replicates the content distribution function without needing complex high-bandwidth infrastructure.

AI summary
Methods and apparatus for providing content to users of a network that can be selectively recorded via the user's equipment. In an exemplary embodiment, the network comprises a hybrid fiber coax (HFC) network, and on-demand (OD) sessions are used to provide high-speed download of the requested content to the users. The user's equipment (e.g., set-top box) is equipped with a high-density recording device which can both record the content onto a selected medium (e.g., DVD) and optionally provide copyright protection via one or more means such as limiting the number of copies that can be made, and/or digital watermarking. The network operator can also restrict the establishment of the on-demand sessions and/or release of the content to subscribers based on parameters including prior purchase of the content by the user, and the timing of the release of the same content via other distribution channels such as rental and retail.
