Description
Technical Field
The present invention relates to the field of play control, and in particular, to a method and a system for controlling skip play of a movie.
Background
In recent years, in order to guarantee the legal rights and interests of audiences, movies with the patch advertisements are required to be directly played by skipping the advertisements at the cinema where the advertisements are delivered. However, the existing zapping control schemes are not compatible with the popular show servers on the market, since different theaters and even different cinemas in the same theater may use different brands of show servers, and some of the show servers themselves do not support the zapping operation.
Based on this, when the existing projection server is used to implement the jumping play, the following problems are faced: for the showing server supporting the skip-playing instruction, an operator must manually create a play list for adding the skip-playing instruction on the showing server, but cannot automatically create and issue the play list through a Theater Management System (TMS); and secondly, for the projection server which does not support the skip-play instruction, the skip-play operation cannot be realized through the mode.
And in recent years, a new generation of presentation servers support a skip function, with the skip operation being controlled entirely by the server side. However, servers of old models or low versions do not support skip-casting themselves, but have a large market share. In order to prevent the loss of customer resources and also try to improve the viewing quality, the TMS must control the presentation server through other ways to implement the skip operation.

The POS system is used to issue a film show plan to the TMS (TMS takes the latest schedule every 5 minutes). The advertisement scheduling platform is used for pushing an advertisement showing plan to the TMS. The film information maintenance platform is used for pushing the corresponding relation of the film to the TMS, and the corresponding relation comprises a film ranking number, a language type, a dragon mark offset, a subtitle offset and the like, wherein the dragon mark offset is the starting position of the feature relative to the patch advertisement, namely the position where the feature really starts playing. The Theatre Management System (TMS) mainly performs the functions of content management, SPL creation, and controlling the presentation server playing resources.
Based on the system architecture, the present invention provides a film playback control method, as shown in fig. 1, the film playback control method includes:
step 100: and acquiring a POS schedule and an advertisement schedule.
Step 101: and generating a play list according to the POS schedule and the advertisement schedule. The playlist includes a first playlist and a second playlist. The first playlist includes black field files. The black field file includes a first CUE instruction. The first CUE instruction comprises a skip broadcast request instruction of the dragon mark offset, and the first CUE instruction is used for sending a skip broadcast request to the cinema management system when the showing server executes a black field. The second playlist includes a second CUE. The second CUE is a presentation server interface call.
Step 102: and generating a skip action command according to the playlist. The skip action command comprises: pause action command, switch action command, drag and drop action command, and play action command.
The method specifically comprises the following steps:
the model of the current showing server and the corresponding relation between the showing server model and the play list stored in the cinema management system are obtained. The showing server of the first type of model corresponds to the first playing sub-list, and the showing server of the second type of model corresponds to the second playing sub-list. The first type of presentation server is a presentation server capable of sending a skip-play request to the TMS. The second type of presentation server is a presentation server that cannot send a skip request to the TMS.
And determining whether the current showing server is the first play sub-list according to the model and the corresponding relation of the current showing server to obtain a determination result.
And if so, generating a skip playing action command according to the first play sub-list, otherwise, generating the skip playing action command according to the second play sub-list.
Preferably, the generating of the skip play action command according to the first playlist includes:
invoking, by the theatre management system, a pauseslpl interface in the presentation server with the first CUE instruction to control the presentation server to generate the pause action command.
Calling a next interface in the showing server by the cinema management system by adopting a first CUE instruction to control the showing server to generate a switching action command.
Calling a gotoPosition interface in the showing server by adopting a first CUE instruction through the cinema management system, and controlling the showing server to generate a drag-and-drop action command according to the dragon mark offset.
Calling a playpl interface in the presentation server by the cinema management system by using the first CUE instruction to control the presentation server to generate the playback action command.
The calling an interface that is not called in the presentation server according to the second playlist preferably includes:
and calling a gotoPosition interface in the showing server at regular time according to the absolute time offset by adopting a second CUE instruction through the cinema management system.
Step 103: and controlling the film to carry out skip play by adopting the projection server according to the skip play action command.
Based on the above-mentioned movie jumping play control method provided by the present invention, the process of performing data interaction between the TMS and the show server to realize jumping play is shown in fig. 3, and specifically:
step 1, the TMS receives the corresponding relation of the POS schedule, the advertisement schedule and the film from the POS system, the advertisement schedule platform and the film information maintenance level push. The POS schedule and the advertisement schedule are used for the TMS to create the SPL, and the dragon mark offset in the corresponding relation of the film is an important parameter for the skip-play operation.
And 2, the TMS creates an SPL (playlist) based on the received scheduling information. The TMS supports two modes of manual and automatic SPL creation in the invention. And when the SPL is automatically created, the TMS automatically generates the SPL containing the 10s blackfield file according to the POS schedule and the advertisement schedule. When the SPL is created manually, a movie, an advertisement, a CUE for CUE and a 10s black field file stored locally by the TMS are selected for manual creation. The 10s blackfield file contains a CUE for skip _ dragon, i.e., the first CUE, which is used by the presentation server to send a skip-play request to the TMS when executing the command. The advantage of adding the 10s black field file is that accidental phenomena such as screen flashing and the like can be avoided during actual skip broadcasting, and therefore smooth transition of skip broadcasting of the advertisement is guaranteed.
And 3, controlling the playing server to complete the skip playing operation by the TMS. A comparison of a conventional SPL and a multicast-enabled SPL is shown in fig. 4.
And 4, automatically issuing the SPL automatically created by the TMS to the showing server, wherein the SPL manually created needs to be manually selected and issued to the appointed showing server.
And step 5, when the projection server executes the black field of the SPL, performing data interaction with the TMS and completing a series of operations. The operation process is shown in fig. 5, and includes:
1) the SPL pauses: the TMS calls the pauseslpl interface to control the presentation server to pause the SPL, i.e. the black field, currently being presented.
2) Switching playing segments: the TMS calls the next interface to control the showing server to switch from the black field to the starting position of the film, i.e. the starting position of the tile advertisement.
3) Film drag and drop: the TMS calls the goToPositon interface (with the dragon mark offset as a parameter) to control the projection server to jump from the patch advertisement to the dragon mark location.
4) SPL playing: and calling the play by the TMS to control the showing server to play the feature from the dragon mark position.
In a specific application process, although the mode of singly relying on the first playlist to perform the skip-play control in the above scheme can support most of the projection servers on the market to complete the skip-play, there are also some projection servers that cannot be completely compatible, such as the projection server with model number Dolby DSS 100. When the first sub playlist is applied to such a presentation server, it is impossible to call the presentation server API interface to implement the skip-play function by sending a skip-play request to the TMS, and therefore the skip-play function needs to be actually implemented by means of a special processing method. Based on this, a second playlist is introduced in the present invention. The mode of the play-back control including the second playlist is as follows:
step 1, the TMS creates and issues the SPL. The created SPL contains a CUE command that triggers the TMS to call the presentation server goToPosition interface, referred to herein as a special CUE command, i.e., a second CUE command. And the TMS automatically creates an SPL (second sub-playlist) containing a second CUE instruction according to the POS schedule and the advertisement schedule. Alternatively, the TMS manually creates a second sub-playlist according to the locally stored movies, commercials and second CUE instructions.
And 2, the TMS creates a timing task for executing the second CUE instruction. The TMS first obtains configuration information of the cinema exhibition server through the interface, and if it detects that the exhibition server is a special model (such as Dolby DSS100), it will automatically start the timing service, and create a timing task for the SPL: 1) the SPL UUID, absolute time offset, and special CUE are registered. 2) And the TMS calls a gooToPosition interface of the showing server at regular time according to the absolute time offset to finish the skip-play operation.
And 3, after the whole skip-broadcast control is finished, deleting the SPL timing task which has executed the skip-broadcast operation from the timing task list by the TMS, and ending the process.
Then, according to the above-mentioned technical solution including the second playlist of the present invention, different methods are used to trigger the presentation server to complete the skip-play operation, which may include the following specific embodiments:
example 1:
after creating the SPL timing task, the TMS calls a showing server interface to complete the synchronization of TMS system time and showing server system time, which is a necessary premise for accurately executing a special CUE instruction, then inquires the registered timing task every 5ms, synchronizes with the showing server for one time again when finding that the registered SPL is close to a trigger point of absolute time offset (the current system time-the absolute time offset is less than 10ms), and then regularly calls a gotoPosition interface to control the showing server to complete the jumping play according to the absolute time offset.
Example 2:
after the TMS creates the SPL timing task, firstly, the playing state of the current SPL is obtained by calling a showing server interface every 5ms, when the fact that the showing server is showing the advertisement before showing and the execution time difference between the advertisement ending time and the second CUE is within 10ms (recorded as a relative time difference) is inquired, the TMS inquires the timing task of the registered SPL, the absolute time offset is corrected according to the relative time difference, and the TMS calls a GoToPosition interface at regular time to control the showing server to finish the jumping-playing according to the absolute time offset.
The invention also provides a film jumping play control system corresponding to the film jumping play control method. As shown in fig. 6, the movie playback control system includes: the system comprises a schedule acquisition module 1, a play list generation module 2, a skip play action command generation module 3 and a skip play control module 4.
The schedule acquisition module 1 is used for acquiring POS schedules and advertisement schedules.
The play list generating module 2 is used for generating a play list according to the POS schedule and the advertisement schedule. The playlist includes a first playlist and a second playlist. The first playlist includes black field files. The black field file includes a first CUE instruction. The first CUE instruction comprises a skip broadcast request instruction of the dragon mark offset, and the first CUE instruction is used for sending a skip broadcast request to the cinema management system when the showing server executes a black field. The second playlist includes a second CUE. The second CUE is a presentation server interface call.
The skip playing action command generating module 3 is used for generating skip playing action commands according to the play list. The skip action command comprises: pause action command, switch action command, drag and drop action command, and play action command.
And the jumping play control module 4 is used for controlling the film to jump play by adopting the projection server according to the jumping play action command.
Preferably, the skip play action command generating module 3 specifically includes: the device comprises an acquisition unit, a judgment unit and a skip play action command generation unit.
The acquisition unit is used for acquiring the model of the current showing server and the corresponding relation between the showing server model and the play list stored in the cinema management system. The showing server of the first type of model corresponds to the first playing sub-list, and the showing server of the second type of model corresponds to the second playing sub-list. The first type of presentation server is a presentation server capable of sending a skip-play request to the TMS. The second type of presentation server is a presentation server that cannot send a skip request to the TMS.
The judging unit is used for determining whether the current showing server is the first playing sub-list according to the model and the corresponding relation of the current showing server to obtain a determination result.
And the skip playing action command generating unit is used for generating a skip playing action command according to the first play sub-list when the determination result is yes, and otherwise, generating the skip playing action command according to the second play sub-list.
Preferably, the skip play action command generating unit specifically includes: a pause action command generating subunit, a switching action command generating subunit, a drag and drop action command generating subunit, and a play action command generating subunit.
The pause action command generation subunit is configured to call, by the theater management system, a pauseslpl interface in the presentation server by using the first CUE to control the presentation server to generate the pause action command.
The switching action command generating subunit is configured to call, by the theater management system, a next interface in the presentation server with the first CUE instruction to control the presentation server to generate the switching action command.
The drag and drop action command generating subunit is used for calling a gotoPosition interface in the showing server by the cinema management system by adopting a first CUE instruction, and controlling the showing server to generate a drag and drop action command according to the dragon mark offset.
The playback action command generation subunit is configured to call, by the theater management system, a playback interface in the presentation server using the first CUE to control the presentation server to generate the playback action command.
Preferably, the second skip action command generating unit specifically includes: the interface calls the subunit.
The interface calling subunit is used for calling a gotoPosition interface in the showing server at regular time according to the absolute time offset by adopting a second CUE instruction through the cinema management system.
One core point of the present invention is that the SPL generated manually or automatically by the TMS needs to add a 10s black field file before the feature film, for the audience, only the screen is screened for a few seconds (generally less than 10s), the skip broadcast operation process is performed under the condition that they do not sense, and the phenomenon such as sudden screen flashing does not occur, which results in poor viewing experience. Another core point is that the TMS must have absolute control over the presentation servers, and calls the server interface, sends pause, play clip switch, movie drag and drop, and play action commands to the servers, which are then executed one by the presentation servers. It is important to note that the invention works well if the TMS and the presentation server maintain normal communications, since the goodness of network conditions directly affects the correct execution of the individual commands.
But at the same time, it needs to be noticed that some special models of servers can be triggered and controlled to complete the skip broadcast by creating a timing task at the TMS when the servers cannot be processed according to the general method.
It is understood that the various brands of screening servers present in the market contain the above-mentioned universal interface, and the invention has been verified to be feasible, so that it is a more effective solution at present.
