摘　　要：随着我国互联网的发展以及近年来疫情的影响,通过网络进行影片分发的优势逐渐显现。同时,基于当前信息化管理、智能化升级总体发展方向,面对我国影院放映模式多样化发展趋势,本文对当前主流电影分发模式进行分析,提出并实现了一种基于互联网的数字电影数据包(DCP)端到端自动分发方法,实现以影片制作方为起点,以影片放映方为终点,以影片分发方为整体控制端,对影片DCP从分发准备到结束的全流程控制与信息管理,尽可能简化了电影拷贝过程中的人工干预,确保分发影片文件的安全性和完整性,可满足多种电影制作发行放映体系,保证各类影院影片放映的时效性。The advantage of film distribution through the network gradually appears, with the development of the Internet in China and the impact of the epidemic in recent years. This paper analyses the current mainstream film distribution mode, proposes and implements an internet-based end-to-end automatic distribution method of digital cinema package(DCP), based on the overall development direction of information management and intelligent upgrade, and facing the diversified development trend of Chinese cinema projection mode. With the film producer as the starting point, the film projector as the end point, and the film distributor as the overall control point, the method can realise the control and information management of film DCP through the whole process from distribution preparation to completion, which simplifies the manual intervention in the process of film distribution and ensures the security and integrity of the film files as much as possible. In addition, it can meet a variety of film production, distribution and projection system, and ensure the timeliness of different film screenings.
