Cooperative Digital Cinema Content Distribution via Terrestrial Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional distribution of digital cinema content through satellite transmission faces limitations due to limited bandwidth and the physical space requirements of satellite dishes, making it inefficient and costly.
Innovation Solution
A method and system utilizing terrestrial wireless communication and cooperative downloading processes, such as BitTorrent, to distribute digital cinema content by dividing the content into chunks, initially seeding them through dynamically increased downlink bandwidth, and then optimizing peer-to-peer sharing among theaters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If satellite transmission is used to distribute digital cinema content, then content can be delivered to theaters, but bandwidth is limited and physical space for satellite dishes is required
Solution Approach 1:
The patent divides digital cinema content into multiple chunks and distributes them through a peer-to-peer network among theaters. Instead of transmitting complete content through satellite to each theater individually, the content is segmented and shared collectively, reducing the bandwidth burden on satellite transmission while maintaining distribution efficiency.
2Ease of operation
If satellite dishes are installed at theaters for content reception, then digital cinema content can be received, but substantial physical space is occupied
Solution Approach 1:
The patent implements a self-service distribution model where theaters that have already received content chunks act as sources for other theaters. Instead of each theater needing independent satellite reception capability, theaters serve each other by sharing content through peer-to-peer connections, eliminating the need for space-consuming satellite dishes at every location.
3Productivity
If traditional film reels are used for motion picture distribution, then content can be shown in theaters, but the process is expensive and cumbersome
Solution Approach 1:
The patent replaces the mechanical film reel distribution system with a digital peer-to-peer network system. Instead of physically transporting and manually handling film reels, the system uses digital content chunks transmitted through wireless networks and shared among theaters, dramatically simplifying the distribution process and eliminating mechanical complexity.
4Ease of manufacture
If digital cinema content is delivered on hard drives to each theater, then distribution costs are reduced, but the initial equipment expense is substantial
Solution Approach 1:
The patent creates a universal peer-to-peer distribution system where theaters serve multiple functions: they are both content receivers and content sources. Instead of each theater needing dedicated hard drive infrastructure for content storage and distribution, the system allows any theater to share content with others, reducing individual hardware investment while maintaining distribution capability.

AI summary
A method for distributing a digital motion picture to multiple theaters in a region via terrestrial wireless communication. The motion picture is divided into chunks, and the chunks are transmitted to particular initial seed theaters in the region. To facilitate the initial seeding, downlink bandwidth on various wireless links is dynamically increased. Once the initial seeding is complete, the downlink bandwidth is decreased and is preferably equalized substantially with uplink bandwidth. The theaters in the region are then directed to begin peer-to-peer sharing of the chunks with each other, possibly through use of BitTorrent or other cooperative downloading process from the initial seed theaters. Ultimately, all of the theaters in the region thereby obtain all of the chunks of the motion picture and can conveniently present the motion picture to audiences.
