Description
Technical Field
The invention relates to the field of data processing, in particular to a method and a system for synchronously playing a film by a primary server and a secondary server.
Background
There are two ways to make a digital cinema package DCP for 3D movies currently in the industry, where the digital cinema package DCP meets the digital cinema alliance DCI specification. The two ways of making the digital cinema package DCP of the 3D movie are respectively: (1) coding and packaging the left and right eye image sequence frames of the 3D image into the same DCP file, and creating 1 CPL; (2) the left and right eye image sequence frames of the 3D image are respectively packed into two DCP files, i.e., a left eye signal DCP and a right eye signal DCP, and 2 pieces of basic information (Composition Playlists, CPL) in which digital cinema program packages are recorded are created at the same time and respectively correspond to the left and right eye DCPs.
When the cinema uses double projectors and double servers to perform 2D or 3D film projection according to a main-auxiliary or main-auxiliary synchronous mode (hereinafter referred to as 'double-machine synchronization'), the mode (1) is still a 3D film DCP production mode generally adopted in the industry. According to the mode (1), the present projection control system used in the cinema needs to copy the same DCP files (CPL is the same) in the primary and secondary servers, and then needs to create movie play lists (SPLs) containing the same movie CPL names in the primary and secondary servers, respectively, for playing.
In the above SPL creation process, because different servers respond differently or manual data operations are different, the SPL may have a certain error, so that the problems of asynchronous pictures of the primary and secondary servers or non-synchronous short-film pairs occur during playing.
Under the existing dual-computer synchronous playing mode, the secondary (or secondary) server SPL is created in a way that the controller performs same-sequence and same-name copying according to the CPL sequence and the CPL name in the created SPL of the host server or a cinema exhibitor manually operates and creates the SPL on the secondary (or secondary) server. Both methods cannot meet the requirement that when the 3D movie DCP is produced in the mode (2), that is, the 3D cp is the left and right DCP, the SPL of the secondary server is automatically created in real time, that is, the showing quality and the showing efficiency of the cinema cannot be ensured, and content editing errors are easily caused, so that the 3D movie cannot be played or the left and right eye pictures are asynchronous and inconsistent
