[0001] Field of the Invention
[0002] The present invention relates to audio playback in a mobile device and more particularly to audio playback in coordination with external video playback.
[0003] Description of the Related Art
[0004] Video playback refers to the presentation on a display substrate of previously recorded video imagery. Historically, video playback included merely the projection of a multiplicity of frames stored in a pancake of film onto screen¨typically fabric. Audio playback simultaneously occurred with the playback of video imagery in a coordinated fashion based upon the transduction of optical patterns imprinted upon the film in association with one or more frames of imagery also imprinted upon the film.
Thus, the coordination of playback of both audio and video remained the responsibility of a single projection device in the context of traditional film projection.
Thus, the coordination of playback of both audio and video remained the responsibility of a single projection device in the context of traditional film projection.
[0005] Unlike motion pictures, in the scholastic environment and even in the context of modern visual presentations, visual playback of a series of images such as a slide show occur separately from the playback of accompanying audio. In this regard, it is customary for the presenter to initiate playback, and in response to a particular cue, such as the presentation of a slide that states, "press play now", the presenter can manually initiate playback of an audio cassette to audibly supplement the presentation of a series of slides in the slide show. However, the necessity of precision in coordinating the playback of the audio cassette with the presentation of different slides is lacking in that each slide of the slide show may remain visible on a presentation screen for an extended duration.
[0006] Coordinating the playback of audio separately from the projection of a film in a movie theater is not a problem of present consideration because modern file projectors manage both audio and video playback. However, circumstances arise where external audio may be desired in supplement to or in replacement of the audio inherently present during the projection of a film. For example, for an audience member who comprehends a language other than the language of a presented film and other audience members, it is desirable to simulcast audio of a language native to the audience member in lieu of the audio of the presented film that differs from the language of the audience member. Yet, coordinating the synchronized playback of the supplemental audio with the playback of the video without the cooperation of the projectionist of the film can be a manually intensive process of timing the initiation of the playback of the supplemental audio in respect to a particular cue of the film.
[0007] In recent years, several technologies have been developed in respect to the simultaneous playback of audio in connection with the presentation of a film in a movie theater. In particular, in U.S. Patent Application Publication No.
2013/0272672 by Rondon et al., a method of providing alternative audio for combined video and audio content is described in which a current playback position of the combined video and audio content is determined in a mobile device and the alternative audio is synchronized with the determined current playback position. Thereafter, the alternative audio synchronized with the current playback position is played back in the mobile device to a viewer of content such that the alternative audio replaces the original audio, which is otherwise heard by other viewers. Of note, in the Rondon patent application, the current playback position is determined through the use of watermark detection in which a watermark embedded in the combined video is detected by a microphone and mapped to a playback position in the alternative audio. Thus, absent the utilization of watermarks, synchronization of the alternative audio and the combined video is not possible.

[0008]

Finally, in response to a determination that the mobile computing device is proximate to the selected movie theater, a start time of .a next scheduled presentation of the selected motion picture is determined and audio synchronization of the alternative audio file triggered at a time that is within a threshold of the determined start time.
[0009] In one aspect of the embodiment, the audio synchronization includes receiving audio through a microphone of the mobile computing device, selecting a portion of the received audio and comparing the portion of the received audio to pre-stored audio portions in a table in the mobile computing device that maps the pre-stored audio portions to an index into the alternative audio file. As such, the portion of the received audio is matched to one of the pre-stored audio portions in the table and the alternative audio file is played back in the mobile computing device from a location indicated by an index mapped to the mapped one of the pre-stored audio portions.
[0010] In another aspect of the embodiment, multiple different movie theaters corresponding to different selected alternative audio files downloaded in connection with corresponding ones of the the theaters are geo-fenced and it is then determined that the mobile computing device is proximate to one of the movie theaters when the mobile computing device is geo-located within a geo-fence corresponding to the one of the movie theaters. In yet another aspect of the embodiment, when it is determined that audio synchronization of the alternative audio file has failed, audio synchronization is re-triggered. However, audio synchronization of the alternative audio file is discontinued in response to a manual directive received in the mobile computing device.
[0011] In another embodiment of the invention, a mobile data processing system is configured for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture.
The system includes a mobile computing device with memory and at least one processor and fixed storage disposed in the mobile computing device. The system also includes an audio synchronization application executing in the memory of the mobile computing device.
The application includes program code enabled upon execution to select a motion picture, corresponding theater and start times of the motion picture in a user interface to the application, download into the fixed storage an alternative audio file for the selected motion picture, detect a location of the mobile computing device, and to respond to a determination that the mobile computing device is proximate to the movie theater by determining a start time of a next scheduled presentation of the selected motion picture and triggering audio synchronization of the alternative audio file at a time that is within a threshold of the determined start time.

DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE INVENTION
[0017] Embodiments of the invention provide for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. In accordance with an embodiment of the invention, an alternative audio file is retrieved into fixed storage of a mobile device in connection with a particular motion picture and corresponding movie theater in which the motion picture is scheduled to be presented and a scheduled start time for the motion picture.
Thereafter, a location of a mobile device is detected proximate to the movie theater. A
current time is determined and a next presentation of the particular motion picture determined as well. Once the time of the next presentation is reached, a microphone in the mobile device is activated and receives audio input. The audio input is compared to known audio portions of the particular motion picture in order to identify a contemporaneously presented portion of the particular motion picture. As such, the identified contemporaneously presented portion of the particular motion picture is mapped to a location in the alternative audio file and the alternative audio file is played back from the mapped location. In this way, synchronization of the playback of the alternative audio file is achieved in an automated fashion without requiring the use of embedded watermarks in the particular motion picture.
100181 In further illustration, Figure 1 pictorially shows a process for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. As shown in Figure 1, an audio synchronization module 300 executing in mobile device 100 retrieves a list of available movies 110 and presents the list in a user interface 120 displayed within the mobile device 100. Once one of the movies 110 is selected in the list, a corresponding selection of movie theaters in which the selected one of the movies 110 is scheduled to be presented is selected and the audio synchronization module 300 retrieves a listing of times 170 when the screening 190 is to occur at the selected one of the theaters 160. The audio synchronization module 300 retrieves from audio track data store 130 an audio track 140 corresponding to a selected one of the movies 110 and selected one of the theaters 160. Thereafter, the audio synchronization module 300 monitors the geographic location of the mobile device 100.
[0019] The audio synchronization module 300 detects the proximity of the mobile device 100 to the selected one of the movie theaters 160 by detecting the geographic coordinates of the mobile device 100 within a geo-fence 150 of the selected one of the movie theaters 160 in which a screening 190 of the selected one of the movies 110 is to be presented. In response to detecting the proximity of the mobile device 100 to the selected one of the movie theaters 160, a clock 180 in the mobile device 100 is then continuously monitored to determine when the screening 190 begins. Responsive to the clock 180 indicating commencement of the screening 190, microphone 165 in the mobile device 100 receives audio input 175 from the screening 190 and matches the audio input 175 to a track location 185 in the audio track 140. Finally, the audio synchronization module 300 plays back the audio track 140 beginning from the track location 185 to produce audio 195 synchronized with the screening 190.
[0020] The process described in connection with Figure 1 may be implemented in a mobile data processing system. In yet further illustration, Figure 2 schematically illustrates a mobile data processing system configured for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. The system includes a mobile computing device 200 communicatively coupled to a media server 210 over computer communications network 220. The mobile computing device 200 includes memory 230 and at least one processor 240 and fixed storage 250 such as a solid state memory device. The mobile computing device 200 also includes a display 260, audio input and output 280 (for example a microphone and speakers or audio output port) and a network interface 270 permitting network communications between the mobile computing device 200 and endpoints over the computer communications network 220. Optionally, global positioning system (GPS) circuitry 290 is included in the mobile computing device.
[0021] Of note, an audio synchronization module 300 is stored in the fixed storage 250 and executes by the processor 240 once loaded into memory 230. The audio synchronization module 300 includes program code that when executed by the processor 240 retrieves an alternative audio file into the fixed storage 250 from the media server 210 for a selected movie and corresponding movie theater in which the selected movie is scheduled to be presented repeatedly over a period of time. Thereafter, the program code geo-locates the mobile computing device 200, for instance, by accessing the GPS
circuitry 290, and determines if the mobile computing device 200 is proximate to the movie theater in which the selected movie is scheduled to be presented repeatedly over a period of time. Then, the program code retrieves a current time in the mobile computing device 200 and retrieves from an information source over the computer communications network 220, a start time of a next presentation of the selected movie.
[0022] Once the start time of the next presentation is reached, the program code activates the audio input and output port 280 and receives audio input. The program code then compares the audio input to known audio portions of the selected movie in order to identify a contemporaneously presented portion of the selected movie.
Consequently, the program code identifies a contemporaneously presented portion of the selected movie and maps the contemporaneously presented portion to a location in the alternative audio file stored in the fixed storage 250. Finally, the program code directs the playback through the audio input and output port 280 of the alternative audio file from the mapped location.
In this way, synchronization of the playback of the alternative audio file is achieved in an automated fashion without requiring the use of embedded watermarks in the selected movie.
[0023] In more particular illustration of the operation of the audio synchronization module 300, Figure 3 is a flow chart illustrating a process for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. Beginning in block 310, a movie is selected from a list of movies in a user interface in the display of the mobile computing device. In block 320, a theater with start times in which the selected movie is scheduled to be presented repeatedly over a period of time is displayed and selected and in block 330, an alternative audio track for the selected movie is retrieved from over the computer communications network. In block 340, a geo-location of the mobile computing device is monitored and, in decision block 350 it is determined whether or not the mobile computing device has become geographically proximate to the selected movie theater, for instance if the mobile computing device has entered a geo-fenced area associated with the selected movie theater.
[0024] In block 360, the play times for the selected movie are retrieved for the movie theater, and the current time as measured on the mobile computing device and compared to the play times for the selected movie. In decision block 370, it is then determined if the play time is the same or within a threshold period of time of the current time as measured by the mobile computing device. If so, in block 380 audio input is acquired through the microphone of the mobile computing device. In block 390, the acquired audio is mapped to an index in the alternative audio track, for instance, by comparing digital features of the acquired audio to pre-stored digital features of different portions of the alternative audio track that are respectively mapped different indexes of the alternative audio track. Finally, in block 400, playback of the alternative audio track commences at the mapped index.

100321 As can be seen from the above description, the methods, systems and computer program products described herein represent significantly more than merely using categories to organize, store and transmit information and organizing information through mathematical correlations. The methods for continuous automated audio synchronization are in fact an improvement to the technology of audio-video synchronization in a movie theater context, as they enable synchronization of the playback of the alternative audio file without requiring the use of embedded watermarks in the selected movie.
This simplifies the audio-video synchronization process, and allows it to be applied to an existing movie that does not include embedded watermarks. Thus, the presently described technology may be considered to be a solution to a computer problem.
Moreover, the methods for continuous automated audio synchronization are applied by using a particular machine in a particular context, namely a mobile computing device equipped with a microphone in conjunction with a physical movie theater installation. As such, the claimed methods for continuous automated audio synchronization are confined to public movie theatre settings. Furthermore, in construing the claims, it is to be understood that the use of a mobile computing device to implement the embodiments described herein is essential.
[0033] Having thus described the invention of the present application in detail and by reference to embodiments thereof, it will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims as follows:
Thereafter, a location of a mobile device is detected proximate to the movie theater. A
current time is determined and a next presentation of the particular motion picture determined as well. Once the time of the next presentation is reached, a microphone in the mobile device is activated and receives audio input. The audio input is compared to known audio portions of the particular motion picture in order to identify a contemporaneously presented portion of the particular motion picture. As such, the identified contemporaneously presented portion of the particular motion picture is mapped to a location in the alternative audio file and the alternative audio file is played back from the mapped location. In this way, synchronization of the playback of the alternative audio file is achieved in an automated fashion without requiring the use of embedded watermarks in the particular motion picture.
100181 In further illustration, Figure 1 pictorially shows a process for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. As shown in Figure 1, an audio synchronization module 300 executing in mobile device 100 retrieves a list of available movies 110 and presents the list in a user interface 120 displayed within the mobile device 100. Once one of the movies 110 is selected in the list, a corresponding selection of movie theaters in which the selected one of the movies 110 is scheduled to be presented is selected and the audio synchronization module 300 retrieves a listing of times 170 when the screening 190 is to occur at the selected one of the theaters 160. The audio synchronization module 300 retrieves from audio track data store 130 an audio track 140 corresponding to a selected one of the movies 110 and selected one of the theaters 160. Thereafter, the audio synchronization module 300 monitors the geographic location of the mobile device 100.
[0019] The audio synchronization module 300 detects the proximity of the mobile device 100 to the selected one of the movie theaters 160 by detecting the geographic coordinates of the mobile device 100 within a geo-fence 150 of the selected one of the movie theaters 160 in which a screening 190 of the selected one of the movies 110 is to be presented. In response to detecting the proximity of the mobile device 100 to the selected one of the movie theaters 160, a clock 180 in the mobile device 100 is then continuously monitored to determine when the screening 190 begins. Responsive to the clock 180 indicating commencement of the screening 190, microphone 165 in the mobile device 100 receives audio input 175 from the screening 190 and matches the audio input 175 to a track location 185 in the audio track 140. Finally, the audio synchronization module 300 plays back the audio track 140 beginning from the track location 185 to produce audio 195 synchronized with the screening 190.
[0020] The process described in connection with Figure 1 may be implemented in a mobile data processing system. In yet further illustration, Figure 2 schematically illustrates a mobile data processing system configured for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. The system includes a mobile computing device 200 communicatively coupled to a media server 210 over computer communications network 220. The mobile computing device 200 includes memory 230 and at least one processor 240 and fixed storage 250 such as a solid state memory device. The mobile computing device 200 also includes a display 260, audio input and output 280 (for example a microphone and speakers or audio output port) and a network interface 270 permitting network communications between the mobile computing device 200 and endpoints over the computer communications network 220. Optionally, global positioning system (GPS) circuitry 290 is included in the mobile computing device.
[0021] Of note, an audio synchronization module 300 is stored in the fixed storage 250 and executes by the processor 240 once loaded into memory 230. The audio synchronization module 300 includes program code that when executed by the processor 240 retrieves an alternative audio file into the fixed storage 250 from the media server 210 for a selected movie and corresponding movie theater in which the selected movie is scheduled to be presented repeatedly over a period of time. Thereafter, the program code geo-locates the mobile computing device 200, for instance, by accessing the GPS
circuitry 290, and determines if the mobile computing device 200 is proximate to the movie theater in which the selected movie is scheduled to be presented repeatedly over a period of time. Then, the program code retrieves a current time in the mobile computing device 200 and retrieves from an information source over the computer communications network 220, a start time of a next presentation of the selected movie.
[0022] Once the start time of the next presentation is reached, the program code activates the audio input and output port 280 and receives audio input. The program code then compares the audio input to known audio portions of the selected movie in order to identify a contemporaneously presented portion of the selected movie.
Consequently, the program code identifies a contemporaneously presented portion of the selected movie and maps the contemporaneously presented portion to a location in the alternative audio file stored in the fixed storage 250. Finally, the program code directs the playback through the audio input and output port 280 of the alternative audio file from the mapped location.
In this way, synchronization of the playback of the alternative audio file is achieved in an automated fashion without requiring the use of embedded watermarks in the selected movie.
[0023] In more particular illustration of the operation of the audio synchronization module 300, Figure 3 is a flow chart illustrating a process for the continuous automated audio synchronization of an alternative audio track with the playback of the combined audio and video of a motion picture. Beginning in block 310, a movie is selected from a list of movies in a user interface in the display of the mobile computing device. In block 320, a theater with start times in which the selected movie is scheduled to be presented repeatedly over a period of time is displayed and selected and in block 330, an alternative audio track for the selected movie is retrieved from over the computer communications network. In block 340, a geo-location of the mobile computing device is monitored and, in decision block 350 it is determined whether or not the mobile computing device has become geographically proximate to the selected movie theater, for instance if the mobile computing device has entered a geo-fenced area associated with the selected movie theater.
[0024] In block 360, the play times for the selected movie are retrieved for the movie theater, and the current time as measured on the mobile computing device and compared to the play times for the selected movie. In decision block 370, it is then determined if the play time is the same or within a threshold period of time of the current time as measured by the mobile computing device. If so, in block 380 audio input is acquired through the microphone of the mobile computing device. In block 390, the acquired audio is mapped to an index in the alternative audio track, for instance, by comparing digital features of the acquired audio to pre-stored digital features of different portions of the alternative audio track that are respectively mapped different indexes of the alternative audio track. Finally, in block 400, playback of the alternative audio track commences at the mapped index.
