METHOD AND SYSTEM FOR SYNCHRONIZATION OF MULTIPLE CONTENT STREAMS

FIELD OF THE INVENTION

Generally, the disclosure relates to video processing. In particular, the disclosure relates to the methods, apparatus and devices for synchronizing video content captured from multiple video capturing devices.

BACKGROUND

Digital photography has made the process of capturing content very simple. Cinematographers today generally use multiple video cameras or capturing devices to capture content of a particular event. The capturing devices may be used simultaneously or in succession.

When there is content from multiple capturing devices of an event there is need to synchronize the content originating from the multiple capturing devices in order to present the content in an effective manner to an audience. In order to synchronize the content from multiple capturing devices, a process known as editing may be performed. During editing, the video content from the multiple capturing devices may be viewed and the appropriate sections of the content from the multiple capturing devices may be synchronized to produce a final video.

Today, there are many methods employed to synchronize motion pictures captured across various capturing devices simultaneously. One such method is based on a clapboard in which an operator claps the clapboard within visual and aural reach of all the capturing devices simultaneously recording a scene. Thereafter, a person may manually line up content from various capturing devices and synchronize them to produce a coherent video content. The manual process may be cumbersome and time consuming.

Further, an alternative to the clapboard based method may utilize a software configured to synchronize video tracks based on their audio track content. The use of such software may reduce the time but the process may still be time consuming and confusing to the person performing the editing.

A further solution to synchronizing the content from multiple capturing devices may include using a dedicated time code sync hardware that connects to all the capturing devices. The dedicated time code sync hardware may be expensive and may require highly qualified technician to connect the hardware to all the capturing devices. Therefore, the dedicated time sync hardware may not be cost effective for widespread use.

Therefore, there is a need for improved methods and systems for synchronizing video content from multiple capturing devices in order.

I. PLATFORM OVERVIEW

This overview is provided to introduce a selection of concepts in a simplified form that are further described below. This overview is not intended to identify key features or essential features of the claimed subject matter. Nor is this overview intended to be used to limit the claimed subject matter's scope.

In some embodiments, the disclosure relates to a method of facilitating synchronization of a plurality of video streams captured from multiple angles. The synchronization of the plurality of video streams may be enabled by a syncing device. In some embodiments, the syncing device may be a tablet or any other mobile device that may be programmed to generate a code image to be used for syncing multi-angle content captured from a plurality of cameras. In some other embodiments, the syncing device may include on-scene accessories such as strobe light. Further, the plurality of cameras used for capturing the video streams may be, for example, but not limited to, film based cameras and digital cameras. Furthermore, the syncing device may be placed in front of a first camera during the first camera's recording session. Further, the syncing device may display a code image which may be captured by the first camera. The code image may appear on the screen of the syncing device and may be recorded into the first content stream captured by the first camera. Similarly, the syncing device may then be placed in front of a second camera during the second camera's recording session. Further, the syncing device may display an updated code image that appears on the screen of the syncing device. Subsequently, the second camera may capture the updated code image in the second content stream.

In some embodiments, the syncing device may display the same code image to each of the first camera and the second camera. Further, in some embodiments, the code image generated by the syncing device may be a particular pattern of flashes or a complex visual. The complex visual may include a 2 dimensional barcode such as a QR code.

In some cases, a single syncing device may be used with multiple cameras by introducing the syncing device at different instances of time during the filming. In some other instances, a single syncing device may be placed in the field of view of multiple cameras so that it is captured by all the cameras. Accordingly, the code image generated by the syncing device may be captured by all the cameras simultaneously.

In some embodiments, multiple syncing devices may be used in the multi-angle camera setup. In this case, the multiple syncing devices may first be synced together. The syncing of the multiple syncing devices may be achieved, for example, by connecting the syncing device through a personal area network, such as Bluetooth or Zig-Bee. Further, in this setup, all the syncing devices may be placed in front of their corresponding cameras at different times. However, in some instances, the syncing devices may be placed in front of the corresponding cameras at the same time.

Both the foregoing overview and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing overview and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.

II. PLATFORM CONFIGURATION

FIG. 1 illustrates one possible operating environment through which a platform consistent with embodiments of the present disclosure may be provided. The operating environment may comprise methods, systems, and devices collectively referred to as a platform 100. The platform 100 may include one or more syncing devices 102, such as 102-1 and 102-2 and a plurality of cameras 104 such as 104-1 and 104-2. In some embodiments, syncing device 102-1 and 102-2 may be remotely operated by syncing devices 102. For example, syncing devices 102-1 may be a color coded strobe light remotely operated by syncing devices 102.

Examples of the plurality of cameras 104 include, but are not limited to, for example, still image camera, video camera, smart-phone, tablet computer, laptop computer, sound recorder and thermal imager. Further, a camera device of the plurality of cameras 104 may be replaced by a content capturing means configured to capture content.

In general, the content may include a representation of one or more physical characteristics. For example, in some embodiments, the content may include visual content. Accordingly, the content may be a representation of optical characteristics such as, but not limited to, reflectance, transmittance, luminance and radiance. For instance, visual content corresponding to a scene may include electronic representation, such as, for example, a digital representation, of reflectance of visible light from one or more objects in the scene as captured from two or more viewpoints. Accordingly, the plurality of cameras may be positioned at different spatial coordinates corresponding to the two or more viewpoints. Examples of content may include one or more of, but not limited to, image, video and audio. In various embodiments, the content may correspond to, but without limitation, one or more sensory modalities. The one or more sensory modalities may include visual modality, auditory modality, tactile modality, olfactory modality and gustatory modality.

In order to capture the content, the content capturing means may include one or more sensors configured for sensing one or more physical characteristics corresponding to the content. For example, the content capture means may include an image capturing device configured for sensing electromagnetic radiation in a scene and generating a corresponding electronic representation. Further, the image capturing device may be configured for sensing electromagnetic radiation corresponding to one or more wavelength bands. As an example, the image capturing device may be a video camera configured for sensing electromagnetic radiation in the visible spectrum. As another example, the image capturing device may be configured for sensing electromagnetic radiation in the infrared spectrum. In another embodiment, the content capturing means may include a microphone configured for sensing sound waves and generating a corresponding electronic representation such as, for example, a digital representation.

Moreover, the platform 100 may include a networking environment for facilitating communication between the one or more syncing devices 102 and the plurality of cameras 104. By way of non-limiting example, the platform 100 may be interconnected using a network 106. In some embodiments, the network 106 may comprise a Local Area Network (LAN), a Bluetooth network, a Wi-Fi network and a cellular communication network. In other embodiments the platform 100 may be hosted on a centralized server, such as, for example, a cloud computing service. A user 108 (e.g., director) may access platform 100 through a software application. The software application may be embodied as, for example, but not be limited to, a website, a web application, a desktop application, and a mobile application compatible with a one or more electronic devices. One possible embodiment of the software application may be provided by a syncing application included on electronic devices such as smart phones and tablet computers, wherein the syncing application may be configured to facilitate synchronization of multiple video content streams.

The platform 100 may further include additional computing devices in operative communication with one or more of the one or more syncing devices 102 and the plurality of cameras 104. Although the present disclosure refers to various functions and operations performed by particular components of the platform (e.g., a syncing device or camera device), it should be understood that some platform components may be interchanged with others, and/or, where necessary, combined with other components to perform the functions and operations intended.

As will be detailed with reference to FIG. 1 below, an electronic device through which the platform 100 may be accessed may comprise, but not be limited to, for example, a desktop computer, laptop, a tablet, or mobile telecommunications device. Though the present disclosure is written with reference to a mobile telecommunications device, it should be understood that any computing device may be employed to provide the various embodiments disclosed herein.

The platform 100 may be configured to communicate with each of the devices such as the one or more syncing devices 102 and the plurality of cameras 104 over the network 106. Further, the platform 100 may be configured to provide a user interface to the user 108. Accordingly, the user 108 may interact with the platform 100 in order to initiate display of one or more code images by the one or more syncing devices 102. For example, the platform 100 may display a GUI to the user 108 in order to select one or more of the one or more syncing devices 102 to participate in a collaborative recording session and synchronization of content. Further, the GUI may enable the user 108 to enter commands to initiate a display of one or more code images in the selected one or more of the syncing devices 102. Accordingly, a command entered by the user 108 may then be transmitted to the selected one or more syncing devices 102 over the network 106. Upon receiving the command, the selected one or more syncing devices 102 may display one or more code images which may be captured by the plurality of cameras 104. Subsequently, the content captured by the plurality of cameras 104 may be transferred to the platform 100 over the network 106. The platform 100 may host Non Linear Editing (NLE) Software, which may be used to synchronize the video content captured by the plurality of cameras 104 based on the one or more code images. Further, the platform 100 may include means, such as, for example, a communication interface, capable of communicating with the one or more syncing devices 102.

Referring to FIG. 2A, the one or more syncing devices 102 (individual syncing devices are referred to as 102-1, 102-2 . . . 102-N) configured to be used for generating one or more code images for synchronizing content captured using the plurality of cameras 104 (individual cameras are referred to as 104-1, 104-2 . . . 104-N) is illustrated. Each syncing device in the one or more syncing devices 102 may include a code image generating means configured to generate and display a code image. The code image may be a complex visual. An example code image 202 generated by the syncing device 102-1 is illustrated in FIG. 2B. In some embodiments, a syncing device in the one or more syncing devices 102 may be configured to display a plurality of code images simultaneously. An example of a plurality of code images 204 and 206 simultaneously generated by the syncing device 102-2 is illustrated in FIG. 2C. In another example (not shown in figures), the syncing device 102-2 may display a series of flashes in one portion of the display and an encoded image in another portion of the display. Further, the one or more syncing devices 102 may be configured to generate code images which may be captured in the content using the plurality of cameras 104.

Each of the syncing devices 102 may further include a user interface module and a communication module. For example, the syncing device 102-1 may further include a user interface module 208 configured to receive an indication of a control-input from the user 108. Accordingly, the user interface module 208 may allow the user 108 to directly interact with the syncing device 102-1. In general, the user interface module 208 may be any means configured to receive input from the user 108. In various embodiments, the user interface module 208 may include a Graphical User Interface (GUI) presented on a display device, such as, a touch-screen. In another embodiment, the user interface module 208 may include an input device such as, but not limited to, a keyboard, a mouse, a touch-pad, a stylus, a digital pen, a voice recognition device, a gesture recognition device and a gaze detection device. In some embodiments, the user interface module 208 may be implemented using one or more of hardware and software. Examples of hardware include, but are not limited to, sensors and processors.

In various embodiments, the indication of the control-input may include one or more of a touch on a GUI corresponding to the control-input, a depression of a key corresponding to the control-input, a mouse click on a GUI element corresponding to the control-input, a gesture corresponding to the control-input, a voice command corresponding to the control-input, a gesture corresponding to the control-input and a gaze corresponding to the control-input.

In general, the control-input may represent any information that may be used to control a state of the one or more syncing devices 102. For instance, the control-input may represent information about which operation is to be performed, conditions under which the operation is to be performed and how the operation is to be performed. As an example, the control-input may represent information that may be used to enable or disable a functionality of the one or more syncing devices 102. For example, the control-input may be used to disable the one or more syncing devices 102 after displaying the one or more code images, to ensure that no unnecessary visual artifact may be captured in corresponding video streams. As another example, the control-input may represent information that may be used to trigger the one or more syncing devices 102 to perform one or more operations. Accordingly, the control-input may include an operation indicator corresponding to the one or more operations. Examples of the one or more operations include, but are not limited to, generating a code to be displayed on the screen of the syncing device 102, encoding one or more metadata into the code displayed on the screen, displaying a code image at a particular point in time, connecting to one or more syncing devices 102 such as the syncing device 102-1, transmitting a code image to one or more other syncing devices 102 and displaying the code image so that the code image is captured simultaneously by the plurality of cameras 104.

Further, the control-input may represent information that indicates a context in which the one or more operations are to be performed. The context may generally include values corresponding to situational variables such as, but not limited to, time, place and one or more environmental conditions corresponding to the plurality of cameras 104. For example, the context may include range of coordinates of a region. As another example, the context may include a range of time values. Accordingly, in various embodiments, the one or more syncing devices 102 may be triggered to perform the one or more operations at the range of time values. As yet another example, the context may include a predetermined state of one or more sensors included in the one or more syncing devices 102. The one or more sensors may include, but are not limited to, accelerometer, gyroscope, magnetometer, barometer, thermometer, proximity sensor, light meter and decibel meter. Further, the control-input may also include one or more rules that may specify one or more conditions and corresponding to one or more actions to be performed by the one or more syncing devices 102. For example, a rule may specify the one or more syncing devices 102 to display a code image at a particular instance in time. As another example, a rule may specify initiation of display of a code image by each of the syncing device 102 when the plurality of cameras 104 are capturing a video content.

Furthermore, in various embodiments, the one or more syncing devices 102 may form a network, such that they may be controlled collectively using the network. For example, the control-input may indicate that the one or more syncing devices 102 communicate with each other over the network to coordinate and display one or more code images at one or more time instants.

Additionally, in various embodiments, the syncing device 102-1 may also include a communication module 210 configured to communicate data among one or more of the platform 100, other syncing devices of the one or more syncing devices 102 and the plurality of cameras 104. Further, the communication module 210 may be configured to communicate data over one or more communication channels 106. Accordingly, each of the one or more syncing devices 102 and the plurality of cameras 104 may also include one or more communication modules configured to communicate over the one or more communication channels 106.

The one or more communication channels 106 may include one or more of a common local-area-network connection, a Wi-Fi connection, and a Bluetooth connection. For example, the communication module 210 may include a Bluetooth transceiver configured to perform one or more of transmission and reception of data over a Bluetooth communication channel. As yet another example, the communication module 210 may include a network interface module configured for communicating over a packet switched network such as, for example, the Internet. In various embodiments, each of the platform 100, the one or more syncing devices 102 and the plurality of cameras 104 may be configured to communicate over an ad-hoc wireless network. Accordingly, the platform 100 may be configured to transmit a request to the one or more syncing devices 102 and the plurality of cameras 104 to form the ad-hoc wireless network.

In various embodiments, the communication of data may include wireless transmission of the control-input to the one or more syncing devices 102. Accordingly, the communication module 210 included in the syncing device 102 may be configured to perform one or more of transmission and reception of electromagnetic waves.

In various embodiments, the communication module 210 may be configured for wireless reception of the control-input at the syncing device 102-1. In another embodiment, the communication module 210 may be further configured for wireless transmission of the received control-input to another syncing device such as the syncing device 102-2. A communication module of the syncing device 102-2 may be further configured for wireless transmission of the received control-input to yet another syncing device such as the syncing device 102-3. In yet another embodiment, the communication module 210 may be configured to communicate data to a server (not shown).

FIG. 3 illustrates an exemplary syncing device 102-1 in accordance with various embodiments of the invention. The syncing device 102-1 may further include a code display module 212 and a metadata generation module 214. The code display module 212 may be configured to display at least one code image 202 on a display of the syncing device 102-1, as illustrated in FIG. 2B. The code image may include, but is not limited to, a series of flashes, a two dimensional barcode and an encoded image.

At step 1102, at least one code image may be generated using one or more syncing devices 102. In some embodiments, the one or more syncing devices 102 may be configured to generate code image such as, but not limited to, a one-dimensional barcode, a two-dimensional barcode, a sequence of flashes and a Manchester encoded image. The code image, such as code image 202 may be generated based on metadata.

In some further embodiments, the code image may include a timing information such as a current time, a relative time and a time offset. The metadata may be used by Non Linear Editing (NLE) software to synchronize multiple content streams captured by the plurality of cameras 104.

At step 1104, a first code image displayed by a syncing device (of the one or more syncing devices 102) may be captured in a first captured video content stream of the plurality of video content streams captured by the plurality of cameras 104. In some embodiments, the syncing device may be deployed in the field of view of a first camera device which captures video content. As a result, the code image displayed by the syncing device 102 may be captured by the first camera device. In some embodiments, the syncing device 102 may be programmed to display the code image at a predetermined time interval. Accordingly, the syncing device 102 may be captured in a first video stream captured by the first camera device at the predetermined time interval.

At step 1106, a second code image may be captured by a second video stream captured by a second camera device. The second code image may be generated by the syncing device 102 which was earlier captured by the first camera device. In an instance, the syncing device 102 may generate an updated code image. For example, the second code image may include, one or more of the identification of the second camera device, a second scene identification and a second location. Thereafter, the second code image generated by the syncing device 102 may be captured by the second camera device.

Further, the plurality of the syncing devices may be controlled using a master syncing device 602. The NLE software 804 may be configured to decode the multiple code images generated by the plurality of syncing devices 102 captured by the plurality of cameras 104. Subsequently, at step 1204, the plurality of cameras 104 may capture the code images generated by the plurality of syncing devices 102. Further, the plurality of syncing devices 102 may be configured to display the code at different time instances. In an instance, the director may use the master syncing device 602 for controlling the operation of the plurality of syncing devices 102. Accordingly, the master syncing device 602 may be used to coordinate the plurality of syncing devices for operations such as, but not limited to, type of code image to be displayed, time of display of the code image, duration of display of code image, brightness of the display and the colour of the code image.

Thereafter, the plurality of cameras 104 may be connected to the system 802 which may host the NLE software 804. The NLE software 804 may be configured to retrieve the plurality of video content streams from the plurality of cameras 104. Thereafter, the NLE software 804 may scan the plurality of video content streams for code images. Upon detection of code images, the NLE software 804 may decode the code images to extract one or more metadata required for synchronizing the plurality of video content streams. At step 1206, the plurality of video content streams may be synchronized based on the metadata decoded from the code images from the multiple video content streams. In an exemplary embodiment, the synchronization of the video content may be based on the scene numbers obtained from the code images. In another embodiment, the synchronization of the video content streams may be based on the identification of the camera devices. In some other embodiments, the plurality of video content may be synchronized based on a time value which may be obtained from the code images.

The computer-usable or computer-readable medium may be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific computer-readable medium examples (a non-exhaustive list), the computer-readable medium may include the following: an electrical connection having one or more wires, a portable computer diskette, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, and a portable compact disc read-only memory (CD-ROM). Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory.

Embodiments of the present disclosure, for example, are described above with reference to block diagrams and/or operational illustrations of methods, systems, and computer program products according to embodiments of the disclosure. The functions/acts noted in the blocks may occur out of the order as shown in any flowchart. For example, two blocks shown in succession may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality/acts involved.

While certain embodiments of the disclosure have been described, other embodiments may exist. Furthermore, although embodiments of the present disclosure have been described as being associated with data stored in memory and other storage mediums, data can also be stored on or read from other types of computer-readable media, such as secondary storage devices, like hard disks, solid state storage (e.g., USB drive), or a CD-ROM, a carrier wave from the Internet, or other forms of RAM or ROM. Further, the disclosed methods' stages may be modified in any manner, including by reordering stages and/or inserting or deleting stages, without departing from the disclosure.
