Secured Service Provider Memory for VOD Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video-on-demand (VOD) systems face bandwidth limitations and reduced 'on-demand' functionality due to unicast streaming, which leads to inefficient use of network resources and restrictive viewing schedules with multicast streaming.
Innovation Solution
A system and method that allows service providers to push video, audio, and data files onto a secured memory reserved for the service provider on electronic devices, reducing core network bandwidth and enabling fast, reliable access by subscribers, while maintaining control over memory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unicast streaming is used to deliver video content to subscribers, then each subscriber can access video content on demand, but network bandwidth is dramatically reduced when multiple subscribers request video content
Solution Approach 1:
The patent segments video content delivery by creating two distinct memory spaces: subscriber accessible memory for individual on-demand access and service provider specific memory for centralized content storage. This segmentation allows the system to serve multiple subscribers simultaneously from the same content source, reducing redundant network traffic while maintaining on-demand access capabilities.
Solution Approach 2:
The patent introduces an intermediary memory structure (service provider specific memory) that acts as a buffer between the content source and subscribers. This intermediary stores video content locally at subscriber premises, eliminating the need for continuous network streaming and reducing bandwidth consumption while preserving on-demand access.
2Loss of energy
If multicast streaming is used to deliver video content to all subscribers, then network bandwidth is conserved by streaming content once to multiple subscribers, but subscribers must watch at set times or intervals which undermines the on-demand aspect
Solution Approach 1:
The patent applies preliminary action by pre-storing video content in the service provider specific memory at subscriber premises before it is needed. This allows subscribers to access content on-demand without waiting for multicast streams, while the content is delivered to multiple subscribers in advance through efficient network distribution.
Solution Approach 2:
The patent adds a new dimension to content delivery by creating a local storage layer at subscriber premises. This transforms the traditional single-dimension streaming model into a multi-dimensional system where content can be delivered once to local storage and then accessed indefinitely without additional network traffic.
3Speed
If video content is stored locally at subscriber premises, then access speed and reliability are improved, but network bandwidth resources are consumed during content delivery
Solution Approach 1:
The patent uses preliminary action to deliver and store video content in service provider specific memory at subscriber premises before it is needed. This one-time delivery consumes network bandwidth, but subsequent accesses occur locally at high speed without additional network traffic, resolving the contradiction between access speed and bandwidth consumption.
Data Source
AI summary
A system and method for utilizing a secured service provider memory are disclosed. An electronic device is associated with a subscriber and is in communication with a data distribution network configured to deliver data by a service provider to the subscriber. The data distribution network comprises a server in communication with the data distribution network and the server configured to deliver a stream of data over the data distribution network. The electronic device comprises a first memory communicatively connected to the server. The first memory is configured to receive and store data from the server and it is accessible by the subscriber. A second memory is also communicatively connected to the server. The second memory is configured to receive and store data from the server, though the second memory is accessible only by the service provider.
