Cinema Content Delivery Scheduling for Secure Federated Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The distribution of digital cinema content to cinemas is fragmented and inefficient, involving multiple transfers among different servers, leading to risks of corruption and piracy, and requires significant investment in infrastructure and duplication of systems, with current arrangements being costly and complex.
Innovation Solution
A system and method for distributing digital cinema content using a backbone that schedules and manages transfers to cinema servers, forming federated server groups to centralize distribution, and includes a scheduler to determine optimal transfer times based on show times and traffic conditions, while using predictive models to estimate transfer times and regulate data rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transfers of DCC are performed among different servers controlled by different entities, then distribution flexibility is improved, but the risk of corruption and piracy increases
Solution Approach 1:
The patent introduces a centralized distribution server as an intermediary that all cinemas connect to. This single intermediary point maintains security while enabling flexible distribution to multiple cinemas. The server acts as a controlled gateway that manages all content transfers, preventing unauthorized copying and corruption that would occur with multiple decentralized transfer points.
Solution Approach 2:
The centralized distribution server performs multiple functions: it stores DCC, manages delivery schedules, controls access for multiple cinemas, and monitors transfer integrity. This multi-functional approach consolidates what would otherwise require multiple separate systems, maintaining security while providing flexible distribution services to numerous cinemas simultaneously.
2Adaptability or versatility
If cinemas invest in multiple cache servers to receive DCC from different distributors, then content reception capability is improved, but infrastructure cost increases
Solution Approach 1:
The centralized distribution server serves all cinemas and all distributors through a single infrastructure. Instead of each cinema needing separate cache servers for each distributor, the universal distribution server handles content from any distributor and delivers to any cinema, dramatically reducing infrastructure requirements.
Solution Approach 2:
The patent merges the functions of multiple cache servers into a single centralized distribution server. By combining storage, scheduling, and transfer management capabilities into one system, cinemas eliminate the need to maintain multiple separate servers, reducing both capital expenditure and operational complexity.
3Loss of time
If DCC is transferred closer to the show time, then content freshness is improved, but the risk of transfer failure increases
Solution Approach 1:
The distribution server schedules and initiates DCC transfers in advance of the required show time, accounting for transfer duration and potential delays. This preliminary action ensures content is delivered and verified before the deadline, maintaining both timeliness and reliability by building in a safety buffer.
Solution Approach 2:
The system monitors transfer progress and provides feedback to the scheduling mechanism. If a transfer is running behind schedule or encounters issues, the feedback loop allows for corrective actions such as prioritizing the transfer or alerting operators, ensuring reliable delivery while maintaining optimal timing.
4Measurement precision
If predictive models are used to estimate transfer times, then transfer scheduling accuracy is improved, but system complexity increases
Solution Approach 1:
The predictive model uses historical transfer data and current system conditions to automatically estimate transfer times without requiring manual intervention. The system serves itself by learning from past performance and applying that knowledge to schedule future transfers, improving accuracy while adding minimal operational complexity.
Data Source
AI summary
A system for distributing digital cinema content (DCC) to cinemas integrates with content creators, distributors and cinemas. A backbone that includes a scheduling system operates to automatically transfer DCC to individual cinema IT systems. The scheduler ensures availability of DCC at a cinema IT system in advance of or at a show time. The system may automatically generate key delivery messages. The cinema IT systems may comprise cinema servers that include media players dedicated to specific screens. The cinema servers may be operated as federated server groups. DCC may be stored on any of the cinema servers and played back on any screens in a cinema.
