The present disclosure is directed to content analytics and creation, and more particularly to creating a content design structure that is used to create new content.
Existing content providers such as traditional broadcasting networks, production companies, and over-the-top service providers often produce new content such as movies or television shows through audio/video capture of sets, filming actors/actresses and/or models. A significant amount of time, expense and efforts are usually required in developing scripts, costumes and sets as well as casting, filming and post-production editing in the content creation process. In addition, some existing computer-based post-production tools are used to add or edit computer-generated content such as special visual effects to video content from filming. But these tools often require labor-intensive programming to define attributes, motion paths, and features for an added visual effect, which is subsequently rendered frame-by-frame to produce the visual effect.
In view of this problem, systems and methods are disclosed for generating a content structure that can then be used as a content design building block. Specifically, new content can be automatically generated by combining, replacing or mixing and matching objects, actions, settings, effects, audio, etc., from any number of previously stored content structures to create a new content structure, which is then rendered as a new content segment. Content segments are then stitched together to generate a finished content stream. In this way, new and original content can be created without the traditionally expensive and labor-intensive filming or computer animation processes.
Specifically, a content deconstruction engine is configured to create a content structure by deconstructing a segment of a content asset into an attribute table of structural listing of data fields and corresponding mappings. The data fields correspond to attributes of objects, settings, effects, etc., that appeared in the segment of a content asset, and the mapping includes attribute values corresponding to each attribute. In this way, the content deconstruction engine stores segments of content assets in a deconstructed form as content structures having a table of attributes and mappings of attribute values mapped to the corresponding attributes. These deconstructed content structures provide knowledge of attributes such as features of different objects, movement and interaction patterns between the objects, and relationships between the objects that appear in the original content segments.
To deconstruct a segment of content and generate a content structure, the content deconstruction engine performs pattern recognition on the segment to identify objects such as characters, scenery, lighting, props, action, motion, special effects, audio tracks, and/or the like. For each identified object, the content deconstruction engine determines a plurality of attributes related to the object. For example, an object may be a human character in the content segment and attributes of the human character object may include the height, race, age, gender, hair color, eye color, body type, a facial pattern signature, a movement pattern, a relative location with other objects, an interaction with other objects, and/or the like. The attributes are stored in the attribute table as a listing of data field names in the content structure.
The content deconstruction engine maps attributes of the object to attribute values depicting the actual object that appeared in the content segment, and the corresponding sub-segment within the content segment during which a specific attribute value appears. The attribute value, a presence indicator including the associated start time and end time of the sub-segment during which the respective attribute value is present in the content segment, and the mapping relationship with the respective attribute are collectively, separately, or independently referred to herein as “mapping.” The content deconstruction engine then creates and stores the generated content structure including the attribute table and the associated mapping at a content design database.
The content structure, together with many other previously created and stored content structures can then be used to create customized content. Specifically, a content construction engine is implemented to retrieve one or more previously stored content structures and combine, replace or mix-match objects, settings, effects, audios, etc., from these content structures to create a new content structure. For example, the content construction engine may map relevant attributes of a particular object in a first content structure to attribute values from the mapping in a second content structure. The content construction engine then creates a new content structure having the object structure relating to the particular object being populated with attribute values from the second content structure, e.g., a human object structure can be modified with physical appearance and movement patterns relating to a monster creature derived from the attribute values from the second content structure. In this way, customized new content can be created using the content structure as a framework and customized mapping to fill in the framework without the labor of re-casting, re-setting or re-filming.
The above and other objects and advantages of the disclosure will be apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
among objects within an example content segment are analyzed frame by frame to generate the content structure, according to some embodiments described herein;
The content stream 108 may include, but is not limited to, professionally generated content, digital first content, a live broadcast, a previously stored content asset at a DVR, other broadcasted content, over-the-top (OTT) media stream, video and/or audio files, downloaded content, user-generated content or any media stream, and/or the like. The content deconstruction engine may “slice” the content stream 108 into a plurality of content segments 122a-c at the buffer 120. For example, the content deconstruction engine may determine a starting playback position and an ending playback position for each segment based, on a pre-determined segment duration, e.g., [t1, t2], [t2, t3], [t3, t4], etc. The content segments 122a-c may have the same pre-defined duration lengths or may have different duration lengths. Example lengths for each content segment 122a-c may be pre-defined as 300 ms, 500 ms, 700 ms, and/or the like. Alternatively, the content segments 122a-c may also be defined by chapters, scenes, pauses in audio, close captions, etc., from the content stream 108.
For each determined content segment, e.g., 122a-c, the content deconstruction engine 130 may determine a content structure descriptive of objects and/or other features within the content segment. Specifically, the content deconstruction engine 130 may retrieve and analyze a content segment 122a (or can be any of 122a-c in
For example, for a content segment 122a that features a male character and multiple non-human physical objects such as background settings, props, etc., the content deconstruction engine 130 may perform pattern recognition, based on an object database, to identify an object corresponding to the male character from the segment. Based on a type of the object, for example, when the object is a human object, the content deconstruction engine 130 identifies a list of attributes of each human object, including but not limited to gender, race, height, age, hair color, facial feature pattern, clothing style, status (e.g., static, moving, etc.), and other characteristics of the identified object. The content deconstruction engine further obtains specific attribute values, by content analysis of content segment 122a, corresponding to attributes, e.g., such as gender=“male,” race=“Caucasian,” height=“6,” age=“28,” hair color=“brown,” status=“moving,” etc. The attribute values are included in the mapping 132 associated with the attribute table 131.
The attribute table 131 and the associated mapping 132 are stored in the form of a content structure 133 at storage 319. Specifically, the content structure 133 can then be retrieved to create new content by combining with other deconstructed content structures, by replacing part of the mappings 132 with mappings stored in other content structures, or by any mix-matching with attributes or mappings from other content structures, as further described in
Storage device 319 may include any device for storing electronic data, computer software, or firmware, such as random-access memory, read-only memory, hard drives, optical drives, digital video disc (DVD) recorders, compact disc (CD) recorders, BLU-RAY disc (BD) recorders, BLU-RAY 3D disc recorders, digital video recorders (DVRs, sometimes called a personal video recorders, or PVRs), solid state devices, quantum storage devices, gaming consoles, gaming media, or any other suitable fixed or removable storage devices, and/or any combination of the same. The content structure 133 including the attribute table 131 and mapping 132 may also be accessed at a cloud-based storage, which may be used to supplement a local storage device or instead of the storage device.
As shown in video frames 125a-n, the relative position between the male character and the red car and the relative position between the male character and the house are changing per frame. The content deconstruction engine 130 analyzes each object within each frame to generate attributes in the attribute table 131 and the associated mapping 132.
Specifically, as shown in
In some embodiments, an absolute location attribute (e.g., 136b) is included in the object structure for an object. For example, the content deconstruction engine determines the position point of object 111 as the coordinates (e.g., “X1, Y1, Z1” 136b1 in mapping 132 for 3D content) of the respective center point of the object. The center point of each object can be obtained by locating the minimum rectangular shape covering the respective object. Deconstruction engine 130 continues to plot the absolute location of object 111 over the course of content segment 122a, as shown for example, in mapping 132 a different set of coordinates “X2, Y2, Z2” 136b2 is shown when the location of object 111 changes over time.
The content deconstruction engine 130 further determines relative location attributes for objects. For example, as shown in
The object data structure for object 111 further includes a motion attribute 136e. The content deconstruction engine 130 computes a velocity vector136e1 based on the absolute location change (X2-X, Y2-Y1, Z2-Z1) and a time lapse between the video frames, to represent the attribute value corresponding to the motion attribute for object 111. The velocity vector may change with time, which is indicated in the mapping 132 shown in
In some embodiments, the content deconstruction engine determines a motion of the object by monitoring the relative position change between objects. The content deconstruction engine may retrieve a second video frame (e.g., video frame 126) corresponding to a playback position that is later than the first video frame (e.g., video frame 125), and re-computes a second set of polar coordinates to describe a respective relative location relationship. For example, the content deconstruction engine may compute the relative position between object 111 and object 112 at t2, e.g., described by polar coordinates (L2, θ2) indicative of line segment 215b connecting the two objects 111 and 112. θ2 denotes a relative distance between objects 111 and 112 within the second video frame 126, and θ2 denotes an angle of the vector from a horizontal axis of the video frame 126. The content deconstruction engine generates a relative location change vector as the differences between the polar coordinates (L1, θ1) and (L2, θ2), i.e., (L2-L1, θ2-θ1) as shown in mapping 132 as . Thus, the relative motion attribute (e.g., 136f in
For each attribute, the corresponding attribute value in the mapping 132 may change over time. For example, object 112 appears within frame 125 at t1 but then disappears in frame 126 at t2-meaning attribute values relating to object 112 are not present in the mapping at t2. For another example, the relative location 217a between objects 111 and 112 changes to relative location 217b from frame 125 to frame 126. Thus, the content deconstruction engine 130 further defines each attribute value in the mapping 132 with a respective presence indicator. The presence indicator has a start time and an end time defining the time duration when the specific attribute value is present within the content segment 122a.
including an attribute table 131 and associated mapping 132 generated from video frames of the content segment 122a as shown in
Specifically, attribute table 131 may include an object data structure 134 including attributes relating to an object. The object data structure 134 includes a descriptive structure 135, an action structure 136, an audio structure 137, etc., as shown in
The action structure 136 is descriptive of actions that the object is performing on or to other objects. The action structure 136 lists action name/type 136a (e.g., shooting, riding, kissing, holding, throwing, cutting, catching, etc.), object(s) that the action involves, absolute location 136b of the object with respect to the video frame, relative location 136c relative to other object(s), absolute motion 136c, relative motion 136f, etc. The location and motion attributes 136b-f are similar to those discussed in relation to
The audio structure 137 contains audio information generated by or associated with an object. For example, audio track 137a may represent dialogue spoken by the object; audio track 137b represents the sound of steps of the object running in the street; and audio 137c represents the sound of the object crashing into the front of a car. Each audio track 137a-c may further list attributes including audio type, frequency, pitch, melody, volume, lyrics, instrument, voice signature, etc.
The effects structure 140 lists attributes of a special effect such as an effect type 140a (e.g., fog, smoke, flash, splash, underwater sunlight, spray, glow, spark, explosion, etc.), features 140b (e.g., color, light smoke, heavy smoke, etc.), effect area 140c (e.g., the location of the effect within the frame), and the associated object that the effect is related to.
The scene audio structure 141 lists attributes relating to various audio or sounds associated with the scene, such as a list of scene audio tracks 141a-n. Each scene audio track 141a-n further includes attributes such as audio type, pitch, frequency, melody, volume, etc. Each scene audio track 141a-n further includes an attribute indicative of allocation the audio is associated with, e.g., a siren is related to the left side of the set, a human yelling voice is related to the right side of the set, etc.
For example, feature mappings (e.g., “Caucasian,” “male,” “28 years old,” “brown hair,” “red shirt,” etc.) 135a1-n may be bounded by the time duration when object 111 appears in content segment 122a. State mappings (e.g., “angry,” “tense,” “running,” “jumping,” etc.) 135b1-n may each be bounded by the time when the actual state appears, e.g., state=“running” between t10 and t1x, and then changes to “jumping” between t1x and t1y.
Similarly, mapping 132 further shows action mapping 136a1, absolute location mappings 136b1-2, relative location mappings 215a, 217a, 217b and 218a, absolute motion mapping 136e1, relative motion mapping 136f1-4 (as also discussed in relation to
In another example, mapping 132 includes mappings for the absolute or relative locations, the absolute or relative motions of object 111, as discussed in relation to
Another content structure 133 taking a form similar to XML is provided below:
For another example, for a physical object such as a car, attributes in the object data structure may be hierarchical, including object, object type, object sub-type, object name, make and model, color, etc., and the corresponding mapping may include “non-human object,” “vehicle,” “automobile,” “car,” “BMW,” “SUV X5,” “red,” and/or the like.
The deconstructed content segments 122a1-n, 122b1-n, . . . are then fed to the content deconstruction engine 130 as shown in diagram 1100 in
The content structures 233a-n may be generated in a distributive manner at distributed processors, in parallel by parallel processors, or in any other processing orders. The content structures 233a-n may be stored in database 319 either together collectively, or may be stored separately at distributed servers for later retrieval to construct new content.
In this way, attributes of the object data structure for object 111 are assigned new attribute values from mapping 232, which can change the appearance, state, movement, etc., of the original object 111 to result in a new object. For example, in content structure 133, object feature attributes in attribute table 131, such as race, age, gender, height, skin tone, hair color, eye color, etc., are mapped to attribute values in mapping 132 such as “Caucasian,” “28 years old,” “male,” “6 feet,” “tanned,” “brown hair,” “hazel eyes,” etc. In content structure 233, object feature attributes in attribute table 231, such as species, age, gender, height, skin tone, hair color, eye color, etc., are mapped to “undefined creature,” “mature,” “male,” “56 feet,” “lizard green,” “no hair,” “black eyes,” etc. By mix-matching mapping 232 with attribute table 131, the new content structure 333 has the object data structure for object 111 being mapped to attribute values “undefined creature,” “mature,” “male,” “56 feet,” “lizard green,” “no hair,” “black eyes,” etc.
As shown in
Similarly, another object structure (e.g., indicative of the red car shown in video frames 125a-n in
Thus, by mix-matching a number of previously stored content structures, new content structure 333 is created, which can be used to reconstruct new content showing a monster creature crashing into the Brooklyn Bridge in New York. The content generation process requires little production cost without expensive setting, filming or computer editing that is usually required for content creation of the science fiction genre.
The new content structure 333 shown in
In some embodiments, the content construction engine may automatically determine which mappings from mapping 232 of the content structure 233 can be used to customize object 111 in content structure 133. For example, the content construction engine determines a list of attributes for object 111 that need to be populated or customized, e.g., attributes depicting the physical appearance and movement patterns. The content construction engine may then obtain attribute values from the customized mapping 232 that depict the physical appearance and movement patterns of a monster creature to populate attributes relating to object 111 in content structure 133.
