Definitions

  • This invention relates to method and system for digital cinema presentation.
  • a motion picture or feature show is often introduced by live personnel in each auditorium.
  • Current methods for live introduction require a performer to deliver the introduction at the front of the auditorium, and a projectionist to operate the projection equipment and house automation (including lights, audio, and curtain).
  • the projectionist manually cues up the projection system, and waves through a booth window as a signal to the performer that the system is ready to go. If a microphone is needed by the performer, the microphone input would be routed to the auditorium audio. After the projectionist's signal, the microphone is turned on, and the performer can begin the introduction.
  • the projectionist manually triggers the playout of the feature show.
  • the show playout may also trigger automation systems that switch over the audio, dim the lights, and open the curtains, or these actions may be initiated by the projectionist.
  • Embodiments of the present invention provide an enhancement to a live presentation by implementing a followspot using a composition playlist.
  • One embodiment provides a method for use in digital cinema, which includes playing out a composition playlist, and synchronizing the playout of the composition playlist with a presentation of a live performer.
  • Another embodiment provides a digital cinema system, which includes a processor for playing out a composition playlist, in which the composition playlist includes content to be displayed in coordination with a presentation of a live performer.
  • Figure 1 is a schematic diagram showing components of a digital cinema system
  • Figure 2 is a timeline showing a portion of a playlist that implements one embodiment of the present invention
  • Figure 3 shows an auditorium configured for implementing one embodiment of the present invention
  • Figures 4a-b show a spotlight illuminating a performer at an early stage of a presentation, with and without curtains in front of a screen, respectively;
  • Figures 5a-b show a spotlight illuminating the performer at a later stage of a presentation, with and without curtains in front of a screen, respectively.
  • a show playlist is a file containing a list of composition playlists and/or event playlists, with instructions relating to the sequence in which these playlists are to be played.
  • a composition playlist is a textual list that specifies how a composition is played and the track files required, while an event playlist is a playlist of compositions, and describes an assembly of compositions in sequence.
  • Embodiments of the present invention relate to a method and system for use in digital cinema presentation, in which the playout of digital content from a composition playlist (CPL) is coordinated or synchronized with a live presentation.
  • CPL composition playlist
  • one or more lighting or illumination configurations are provided by executing a CPL.
  • One example involves the generation of a followspot or spotlight, in which the time sequence or evolution of the followspot is coordinated with a live presentation of a performer or an exhibition employee.
  • the performer can also control the playout of the CPL, e.g., by pausing and/or resuming the CPL playout to match the live presentation of arbitrary duration.
  • the content of the CPL can be used to enhance the artistic expression or achieve special effects, e.g., panning the spotlight off-stage with a gradual diminishing size of its iris, thus allowing a more professional theatrical presentation to be achieved without a need for extra personnel to operate a regular spotlight.
  • Such an implementation can be integrated into a show playlist and allows for coordination with other auditorium components (e.g., lights, curtains, audio, etc.) through an automation system.
  • auditorium components e.g., lights, curtains, audio, etc.
  • audio to provide an introduction or fanfare may be present at various points in the followspot simulation content.
  • FIG. 1 depicts one embodiment of a digital cinema system 10 that can be used for implementing embodiments in accordance with the present principles.
  • digital cinema system 10 includes a theater management system 22, a screen management system (SMS) 14, a digital projector 12 and a screen automation system (SAS) 16.
  • SMS screen management system
  • SAS screen automation system
  • the theater management system 22 and the SAS 16 may be omitted, and the SMS 14 can be configured for direct communication with the projector 12 and with automation elements such as curtain 20 and lighting 18.
  • the theater management system manages the overall workflow and equipment within a theater, and provides control, supervision and report status on the theater equipment.
  • a movie theater can have multiple auditoriums, each having its own screen management system, automation system, digital cinema projector and associated screen.
  • FIG. 1 depicts a configuration for one auditorium, with its SMS 14 controlling a projector 12 and SAS 16.
  • Digital cinema system 10 also preferably includes audio equipment suitable for reproducing a sound track in the auditorium for digital projector 12.
  • an audio chain 24 which is connected to both the SMS 14 (to receive digital audio streams) and SAS 16 (for control, e.g., as channel select, volume, mute), may include a number of digital-to-analog converters (e.g., for different channels), equalizers, amplifiers, and in some cases, switchers, digital signal processors, and/or matrix decoders.
  • the audio chain 24 is further connected to one or more speakers 26 installed in the auditorium.
  • the SMS 14 typically includes a digital cinema server 15 that contains instructions and data for controlling both the digital projector 12 as well as the SAS 16.
  • a decoder (not shown) is also included in the digital cinema server 15 for responding to commands received from the theater management system 22. Examples of a digital cinema server include those manufactured by Dolby Laboratories, San Francisco California, Doremi Digital Cinema, Burbank California and Eastman Kodak, Rochester, New York, among others.
  • the SAS 16 controls certain systems such as a theater lighting system 18 and a screen curtain system 20, among others. Control signals can be sent from the SAS 16 to the theater lighting system 18 for controlling the auditorium lighting, or to the screen curtain system 20 for controlling the opening and closing of one or more curtains across a screen.
  • the SAS 16 can also control the audio equipment, e.g., by controlling audio level and the playing of announcements.
  • the digital cinema server 15 provides a data stream, e.g., a video or image stream from a composition playlist, to the digital projector 12.
  • Digital cinema projectors are available from several manufacturers, such as Barco Media & Entertainment, LLC, Collinso Cordova, CA; NEC Corporation of America, Irving, TX; and Sony Electronics, Inc, Park Ridge, NJ; among others.
  • FIG. 2 illustrates a portion of a show playlist (SPL) 200 for use in a digital cinema system, with the direction of timeline 203 indicating the progress of time during playout of the digital content.
  • SPL 200 contains a reference to composition playlist (CPL) 201 of the present invention, with preferably one or more additional CPLs referenced, such as CPL 202, which may correspond to a motion picture or other primary feature presentation.
  • CPL composition playlist
  • SPL 200 preferably contains cues 231 and 233 that can trigger automation sequences in the auditorium, e.g., sequences associated with the start of a show and the feature presentation.
  • a cue 232 may be provided for triggering a specific action, e.g., a pause during the playout of SPL 200, and a marker 230 is preferably provided in CPL 201 for use in connection with positioning the cue 232 within SPL 200.
  • the playout of digital content in a digital cinema system is further discussed by referring to both FIG. 1 and FIG. 2.
  • Instructions in the SPL 200 are acted upon by the server 15 to direct the playout of the digital content, which includes the projection of the audiovisual content on a screen, as well as other actions to be undertaken by one or more components of the cinema system.
  • cues 231, 232, and 233 are used by the screen management system (SMS) 14 to control the automation system 16 of FIG. 2.
  • SMS screen management system
  • the Start of Show cue 231 which is positioned immediately before the first frame of content of the CPL 201, will result in the SMS 14 sending a signal to the automation system 16, e.g., for adjusting the theater lighting 18 to levels appropriate for CPL 201.
  • the SMS 14 may trigger the automation system 16 to adjust the theater lights to levels appropriate for CPL 202.
  • the CPL 201 includes content relating to an illumination pattern or lighting configuration.
  • the CPL 201 can be used to "simulate" a followspot, e.g., as a spotlight for drawing attention to a performer or object on stage.
  • the word "simulate” is used because the followspot is not generated by a physical lighting system such as a conventional spotlight that is pivoted by an operator to track a performer.
  • the illumination pattern generated by the playout of the CPL 201 does provide actual illumination 310 (shown in FIG.
  • FIG. 2 illustrates that CPL 201 references a picture media asset track 210, which includes a series of images to be displayed in sequence, of which images 21 1 -217 are representative.
  • CPL 201 also references an audio media asset track 220, which may contain audio presentation elements such as an introduction 221 and/or a musical score 226.
  • the SPL references a CPL, which in turn references external assets such as picture track file 210 and audio track file 220.
  • CPL CPL
  • present invention is generally applicable to all playlists. For example, if CPL 201 were substituted by an MPEG file, then the SPL will simply reference the MPEG file. There is no need for the CPL to further reference other video or audio files because the MPEG file already includes the associated audio and video content.
  • the sequence of images in the picture track file 210 referenced by CPL 201 provides a presentation that begins with a substantially dark field, as shown in image 211. In image 212, a small bright spot 252 appears near a left edge 242 of the field.
  • a bright spot 253 has a size and position that are different from those of a spot in at least one previous image or frame, e.g., image 212.
  • spot 253 is larger in size compared to spot 252 (e.g., larger diameter), and its distance from the left edge 243 of the image field is also increased compared to spot 252.
  • Images in CPL 201 are provided such that, when the CPL 201 is played out for a time sequence corresponding to images 212, 213 and 214, the presentation will include a bright spot moving away (preferably smoothly) from the edge 242, e.g., in a horizontal direction, until it reaches approximately the center of the image field. This is shown in image 214, whose spot 254 has attained full size, i.e., maximum size among the images 212, 213 and 214 in CPL 201.
  • bright spots 254 and 255 in images 214 and 215 have substantially the same size and position for a given time duration.
  • the bright spot effectively reverses its time sequence or evolution, i.e., decreasing in size and returning towards a position near the edge 242 of the field, as shown by spot 256 in image 216.
  • image 217 the bright spot disappears from the field.
  • the relative positions in the field of images 211-217 correspond approximately to those of a stage or display screen, e.g., bright spot 252 in image 212 will be projected near the left edge of the screen or stage, while spot 254 in image 214 will be positioned near the center of the screen or stage.
  • the light source of the digital projector provides the illumination for the bright spots in the images.
  • Such implementation can be done using a variety of digital projectors from various manufacturers, such as, but not limited to, those previously identified.
  • the sequence of images 211 through 217 is intended to simulate a folio wspot, with a gradual opening of its iris aperture as the followspot moves from one edge of a screen to the center of the screen, pausing for a given time duration (e.g., initiated by cue 232), before gradually closing the iris and returning to the edge of the screen.
  • a given time duration e.g., initiated by cue 232

  • the live presentation is coordinated with the projection of images 211 through 217 (see FIG. 2) onto screen 303.
  • the simulated spotlight 310 illuminating the performer 305 near the center of the screen 303 results from the playout of spots 254 and 255, which are located near the center of their respective image field (in images 214 and 215).
  • Marks 311 and 312 provided on the floor in auditorium 300 are preferably used to identify reference locations that the performer 305 should be positioned during different times of the presentation.
  • mark 31 1 identifies the location of the performer 305 at the beginning of his appearance, which also substantially coincides with the beginning frames of CPL 201.
  • the start of CPL 201 may be indicated to performer 305 by an audio cue such as introduction 221 or a visual cue such as the fading of the house lights triggered by Start of Show cue 231.

  • FIG. 4a The corresponding scene presented to the theater audience is shown in FIG. 4a, with the performer 305 standing in front of closed curtains 304, and alternatively, in FIG. 4b, with the performer 305 standing in front of the screen 303 not equipped with any curtains.
  • spot 310 effectively serves as a spotlight to bring attention to performer 305, with the light from the projector illuminating the performer 305 and a portion of the curtains 304 or screen 303 behind the performer.
  • performer 305 begins to move towards mark 312 at a rate that is about the same as that of spot 210 tracking across screen 303.
  • screen 303 is hidden behind closed curtains 304, which furthers the illusion that the bright spot 310 in the projected images from picture asset file 210 is a conventional spotlight that illuminates not only performer 305, but curtains 304.
  • the pause function can be achieved by issuing a command to the digital cinema server 14, e.g., via remote control 320 by the live performer, or via local control (not shown) of server 14 by other personnel.
  • performer 305 can take as long as is needed to deliver the live presentation. Once the live presentation is finished, the digital cinema presentation can resume. The resumption of the digital cinema presentation can be done by performer 305 using a remote control 320, as shown in
  • FIG. 5a-b which sends a signal to the projector to resume playout of the CPL 201.
  • This remote signal preferably also triggers an automation sequence by the automation system, which may include dimming the house lights further, starting to open curtains 304 (in the example of FIG. 5a), among others.
  • FIG. 5b shows the view with the performer 305 in front of screen 303 that is not equipped with curtains.
  • performer 305 begins his/her exit by moving towards mark 311, and preferably continues past mark 31 1 to exit the stage or auditorium 300.
  • the movement by performer 305 is timed and paced at about the same rate as that of spot 310, which is configured in the CPL 201 (as sequence of images that include images 215, 216 and 217) to move towards the left edge of screen 303 while diminishing in size.
