Description
Technical Field
The invention belongs to the technical field of digital film source processing, and particularly relates to a method and a system for secondarily packaging film contents.
Background
As samsung introduced the first digital cinema projection equipment in the world based on LED cinema screens, the original projector-based traditional cinema projection mode was broken. The LED film screen is a projection device which takes an LED display screen as a display terminal and integrates a digital film projection server, and has the advantages of high brightness, high contrast, strong expansibility, energy conservation, environmental protection, projection space saving and the like compared with a projector used in a traditional projection mode.
In order to normalize the technical standards of LED cinema screens, the international standardization organization in the digital cinema field: DCI (Digital Cinema Initiatives), a new technical standard branch is specially formulated for the LED movie screen product. While, all large issuers of hollywood are actively attempting to optimize own movie works specifically for the LED movie screen, so as to achieve a subtle and absolute projection effect. With the continuous perfection of LED cinema screen product technology standards, and the increasing push to movie versions specific to LED cinema screens, the content review of digital cinema sources will also become more and more.
The content auditing of the digital cinema source is required by the country, each film to be audited in the cinema needs to audit the content of the master of the digital cinema source in the film auditing mechanism specified in the country, the digital cinema source after the auditing can uniformly issue a dragon head (broadcasting in the film head) and a quality qualification tail (broadcasting in the film tail) which can be uniquely identified in the film, then the digital cinema source master after the auditing is copied and distributed by the specified post-production company, and the cinema is shown in the specified date range (the film stage) after the cinema obtains the distributed digital cinema source.
However, digital cinema sources from content audits to theatrical presentations have the following problems:
1. because the film auditing mechanism can only show and audit the digital film sources through the play list in the digital film sources, the film auditing mechanism can hardly truly audit the encrypted and packaged digital film sources frame by frame, and film fragments which are not audited can exist, so that the played film does not meet the playing requirement;
2. the encrypted and packed digital cinema sources are all required to be used together with corresponding license files to be shown during showing, and the license files mainly comprise decryption keys corresponding to the encrypted and packed digital cinema sources and effective showing date ranges (film file periods) of the encrypted and packed digital cinema sources; if a new license file is created by hand and the valid playable date range within the license file is modified (the valid playable date is advanced or retarded), the digital cinema source may be caused to play during the impermissible movie file.
Disclosure of Invention

s2, analyzing the original license file through a digital film license issuing platform to obtain a decryption key of the film and an effective showing date range of the film;
s3, according to the imported film-checking information, readjusting the effective showing date range of the film and the playable position information of the film, and transmitting the decryption key of the original film, the new playable position information of the film and the new film decryption key to the digital film coding system;
s4, after the digital film coding system receives the decryption key of the original film, unpacking and decrypting the original digital film source;
s5, combining the new playable position information of the film, thoroughly deleting the film fragments which are not allowed to be played, performing secondary encryption packaging operation on the film by using a new film decryption key, and generating a secondary packaged digital film source;
s6, importing the secondarily packaged digital cinema sources into a digital cinema distribution system, copying the digital cinema sources to generate a plurality of digital cinema sources for distribution, and recording distribution information of the secondarily packaged digital cinema sources;
s7, generating a plurality of license files containing new film decryption keys and new film effective showing date ranges according to the number of the LED film screens to be shown.
In addition, the invention also provides a system for secondarily packaging film content, which comprises: the digital film coding system is used for carrying out compression, encryption and packaging processing on the original film source and generating a digital film format film source meeting the requirements of DCI specification; the digital film license issuing platform is used for issuing license files corresponding to the encrypted format digital film sources and is responsible for managing the encryption key and the effective playable date range information of each encrypted format digital film source; and a digital cinema distribution system for copying the generated digital cinema format film sources and distributing the copied digital cinema format film sources to theaters as needed while recording distribution information of the digital cinema film sources.
After the digital cinema source is secondarily packed by adopting the invention, the auditing mechanism can truly and effectively control the real playing content of the audited digital cinema source during playing, and simultaneously, the auditing mechanism can truly and effectively control the playable date range of the digital cinema source.

Detailed Description
The following examples are illustrative of the present invention but are not intended to limit the scope of the invention. The conditions in the examples can be further adjusted according to specific conditions, and simple modifications of the method of the invention under the premise of the conception of the invention are all within the scope of the invention as claimed.
A method for secondary packaging of film content realizes real playing content and playable real effective date range control of a digital film source through a digital film coding system, a digital film license issuing platform and a digital film distribution system.
When the digital cinema source is secondarily packetized, as shown in fig. 1, the following steps are performed:
s1, importing an original film source of a digital film into a digital film coding system, and importing an original license file of the digital film and film examination information given by a film examination mechanism into a digital film license issuing platform;
s2, analyzing the original license file through a digital film license issuing platform to obtain a decryption key of the film and an effective showing date range of the film;
s3, according to the imported film-checking information, readjusting the effective showing date range of the film and the playable position information of the film, and transmitting the decryption key of the original film, the new playable position information of the film and the new film decryption key to the digital film coding system;
