Neither of the above two methods can satisfy the above-mentioned 3D movie DCP production method (2), that is, the real-time and automatic creation of the SPL of the secondary server in the case of two DCPs for the left and right eyes in 3DDCP, that is, the projection quality and projection of the theater cannot be guaranteed. Efficiency, content editing errors are prone to occur, resulting in 3D movies that cannot be played or the left and right eye images are out of sync and inconsistent

The invention relates to a method and a system for synchronously playing movies in a master server and a slave server. The method comprises obtaining the main film playlist in the main server; judging whether the main server and the secondary server are in the dual-machine synchronous mode; if the main server and the secondary server are in the dual-machine synchronous mode; The movie of the same name in the playlist; Create the secondary movie playlist of the secondary server according to the movie; The secondary movie playlist is named corresponding to the main movie playlist; The main server and the secondary server are based on the primary movie The playlist or secondary video playlist is used for synchronous video playback; if the primary server and secondary server are not in dual-machine synchronization mode, only the primary video playlist is saved. The present invention provides a method and system for synchronously playing movies on primary and secondary servers, which realizes the automatic creation of SPLs of the primary and secondary servers, making playback smoother and more accurate, and helping cinemas to ensure better projection quality.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a method and a system for synchronously playing movies in a master server and a slave server. Background technique [0002] In the industry, there are currently two methods of producing digital movie program package DCP for 3D movies, among which the digital movie program package DCP meets the DCI specification of the Digital Cinema Alliance. The two ways of making the digital movie program package DCP of 3D movies are: (1) the left and right eye image sequence frames of the 3D image are encoded and packaged into the same DCP file to create a CPL; (2) the left and right eye images of the 3D image The sequence frames are packaged into two DCP files, namely the left-eye signal DCP and the right-eye signal DCP, and two are created to record the basic information of the digital movie program file package (Composition Playlists, CPL), and correspond to the left and right eye DCPs respec...
