Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for updating a playlist of a play server, where the method may include the following steps:
s1: scanning whether the broadcasting server has available advertisement rule files every other time period, and executing S2 when the broadcasting server has available advertisement rule files;
s2: analyzing the advertisement rule file to obtain the effective time in the advertisement rule file, judging whether the advertisement rule file reaches the effective time, and executing S3 when the advertisement rule file reaches the effective time;
s3: determining a playlist SPL corresponding to an identifier of an advertisement rule file obtained by analyzing the advertisement rule file;
s4: and combining the advertisement rule file with the corresponding SPL to generate a new SPL.
In this embodiment, the SPL consists of a feature, an advertisement, an automation command, and a black field. The feature film is a film to be projected, and for films with different formats, JPEG and MPEG are distinguished according to coding formats, 2D and 3D are distinguished according to film types, and wide, masked and full frames are distinguished according to different frame ratios. Advertising: including a forecast picture, a promo picture, a public service advertisement, a pre-showing advertisement, a patch advertisement and a post-showing advertisement; for advertisements with different formats, JPEG and MPEG are distinguished according to coding formats, 2D and 3D are distinguished according to advertisement types, and the advertisements are divided into wide, covered and full according to different frame ratios. An automation command: the playing server remotely controls a special instruction of the operation of the projector, the audio decoder, the field lamp, the UPS, the curtain, the fan and the central control equipment; the corresponding automation instructions are different for different types of servers. Black field: when different video files are switched in playing, a transition video file is used in the middle. For example, when switching from advertisement to feature play, a black field file of 5 to 10 seconds is first played. The playing server: the cinema contains a server for playing the SPL in each movie hall, and the server usually contains a file list of the SPL, the advertisement rule file and the like. The advertisement rule file: an advertising information carrier. The advertisement rule file comprises an identifier, an advertisement sequence and an effective time of the advertisement rule file, wherein the identifier corresponds to the SPLUUID in the SPL. SPLUUID is the unique identity of SPL.
As shown in fig. 2, in one embodiment of the present invention, the method further comprises:
n1: acquiring an SPL in a playing server, judging whether an advertisement rule in the SPL needs to be updated or not, and generating an advertisement rule file containing a new advertisement rule when the advertisement rule needs to be updated;
n2: and sending the advertisement rule file to a playing server.
In addition, advertisement injection software may be used to generate and send advertisement rules to the playout server. The advertisement rules can be generated manually or automatically by accessing a remote platform end.
In an embodiment of the present invention, the specific process of combining the advertisement rule file and the corresponding SPL in step S4 is as follows: and combining the advertisement sequence obtained by analyzing the advertisement rule file with the SPL corresponding to the advertisement rule file.
In this embodiment, the old SPL is combined with the advertisement rules file to generate a new SPL, primarily by completely replacing the advertisement sequences in the old SPL. The advertisement sequence in the advertisement rule file can be replaced with the advertisement sequence in the old SPL, and if the old SPL does not contain the advertisement sequence, the advertisement sequence can be directly inserted in front of the SPL feature.
In one embodiment of the invention, the identification of the advertisement rules file corresponds to at least one SPL.
In this embodiment, since the advertisement sequences added in the multiple SPLs may be identical, a single advertisement rule file may correspond to multiple spluid, that is, the identification of the single advertisement rule file may correspond to multiple SPLs, and a new SPL is generated with the multiple old SPLs.
In an embodiment of the present invention, after step S4, the method further includes:
the new SPL is sent to the playout server.
In this embodiment, in addition to sending the new SPL to the playout server, the corresponding old SPL needs to be deleted from the playout server.
In a word, the method of the invention is used for circularly repeating, and the advertisement sequence can be ensured to be updated in time. The connection is carried out through the local area network, the situation that the network connection is not communicated can not occur, and the advertisement injection software can manually make the advertisement rules, so that the advertisement sequence in the SPL of the cinema can be timely updated when changed; even if the advertisement sequence is updated for many times, only one SPL file is arranged on the playing server of the same SPL of the feature film, and the SPLUUID of the SPL is unique and constant, so that the SPL can be managed by the playing server and a cinema management system conveniently; the advertisement injection software can be accessed to a remote platform end to automatically generate advertisement rules, and is compatible with the old advertisement injection mode; whether an advertisement rule takes effect may be constrained by the time the advertisement rule takes effect.
As shown in fig. 3, an embodiment of the present invention provides an apparatus for updating a playlist of a play server, where the apparatus may include: a scanning module, an analyzing module, a determining module and a combining module, wherein,
the scanning module is used for scanning whether the playing server has available advertisement rule files or not at intervals, and when the playing server has the available advertisement rule files, the analyzing module is triggered;
the analysis module is used for analyzing the advertisement rule file to obtain the effective time in the advertisement rule file, judging whether the advertisement rule file reaches the effective time or not, and triggering the determination module when the advertisement rule file reaches the effective time;
the determining module is used for determining a playlist SPL corresponding to the identifier by analyzing the identifier of the advertisement rule file obtained by the advertisement rule file;
and the combination module is used for combining the advertisement rule file with the SPL determined by the determination module to generate a new SPL.
As shown in fig. 4, in one embodiment of the present invention, the apparatus further comprises: a generating module and a sending module, wherein,
the generating module is used for acquiring the SPL in the playing server, judging whether the advertisement rules in the SPL need to be updated or not, and generating an advertisement rule file containing new advertisement rules when the advertisement rules need to be updated;
