Background
before showing on the film, the distributor sends the film to the cinema through the hard disk in an express mailing mode, data in the hard disk are encrypted, the distributor provides keys for the cinema through other channels, and the key information comprises the valid period of film playing and information of playing equipment. When the movie is shown, the movie is played in three forms: 1. an IMB play (Integrated MediaBlock, Integrated media module); 2. local (IMB) playing and server side playing (the local side automatically switches to cloud playing when a fault occurs); and 3, playing by the server side and playing by a local client (IMB). In the playing process, if the server side has a fault, the server side is automatically switched to the local side for playing. Cinema purchases a corresponding hardware product to deploy the IMB and server in the cinema to reduce film show incidents. While the show incident can have a serious impact on theatre revenue, the chances of a show incident occurring are small (less than 1%), and current solutions require theatres to deploy expensive servers for a small probability of incident. When downloading a film from a server to a hard disk of a projector and playing the film continuously, the phenomenon of network transmission blockage can be generated due to insufficient network bandwidth and network time delay generated by a used network, so that the cinema can not continuously download the film from the server for playing the film continuously. Further, in the transmission process, after being downloaded, the movie resource is also transmitted to the hard disk through the terminal, and in the transmission process, the device transmission delay is generated, so that the movie cannot be played continuously and smoothly.
As can be seen from the above, even if an expensive server is deployed in a theater, smooth continuous playback cannot be ensured due to the limitation of network and equipment, and therefore, how to ensure that the theater can ensure smooth playback of a movie when a movie showing accident occurs is a problem to be solved urgently.
