METHOD AND ELECTRONIC DEVICE FOR PROVIDING VIDEO OF A SPECIFIED PLAYBACK TIME

PRIORITY

This application claims priority under 35 U.S.C. §119 (a) to a Korean Patent Application filed in the Korean Intellectual Property Office on Sep. 24, 2015 and assigned Ser. No. 10-2015-0135291, the contents of which are incorporated herein by reference.

BACKGROUND

1. Field of the Disclosure

The present disclosure relates generally to an electronic device, and more particularly, to a video providing method of an electronic device which is capable of providing a bookmark function for specifying a video playback time.

2. Description of the Related Art

With the recent developments of integrated technology (IT), an electronic device is portable and is able to freely connect to wired/wireless networks. For example, portable electronic devices such as a smartphone or a tablet personal computer (PC) are able to support various functions, such as network connection and playback of multimedia content, in addition to a call function and a message sending/receiving function.

For example, the electronic device plays video content by using a multimedia player program and the played video content is able to be output through a display and/or an audio module embedded in or operatively connected to the electronic device.

During viewing of the video content, a user may separately want to set a certain playback time point or a playback time interval, such as when a favorable scene of the video content is played back, and may watch the video content from the specified playback time point or the specified playback time interval later or repeatedly.

To this end, the electronic device may generate information associated with the playback time point and the playback time interval specified by the user as a separate file (hereinafter “bookmark”). However, in this case, since a separate bookmark file is generated whenever the user specifies the playback time point or the playback time interval, computing/storage resources of the electronic device may be excessively consumed.

Furthermore, even in a user experience (UX), the user may only realize the presence or absence of the bookmark file when the user reproduces video content. Accordingly, when the user does not reproduce the video content, it is difficult to recognize the presence or absence of the bookmark file. As such, there is a need in the art for providing a bookmark function for specifying a video playback time of the video content.

SUMMARY

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a method for allowing the user to specify and set a certain playback time point or a playback time interval of multimedia content without generating a separate bookmark file and a method for easily recognizing the bookmark.

In accordance with an aspect of the present disclosure, an electronic device includes a display, a memory that stores a video file which comprises video data and metadata, and a processor operatively connected with the display and the memory, wherein the metadata comprises information about a specified playback time point or a specified playback time interval among a total playback time of the video data, and wherein, the memory stores instructions that, when executed, cause the processor to output, on the display, a first preview associated with the total playback time of the video data and a second preview associated with the specified playback time point or the specified playback time interval.

In accordance with another aspect of the present disclosure, a video providing method of an electronic device in which a video file comprising video data and metadata is stored includes outputting, on a display, a first preview associated with a total playback time of the video data, and outputting, on the display, a second preview associated with a specified playback time point or a specified playback time interval of the video data, wherein the metadata comprises information about the specified playback time point or the specified playback time interval.

In accordance with another aspect of the present disclosure, an electronic device includes a memory that stores media data, and a processor that plays the media data through a display operatively connected with the electronic device, obtains an input while the media data is played, generates bookmark information corresponding to at least a portion of the media data based at least on the input, and includes the bookmark information in the media data.

FIG. 1 illustrates a block diagram of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 1, an electronic device 100 according to an embodiment of this disclosure may include a bus 110, a display 120, a memory 130, a communication circuit 140, a processor 150, and a cache memory 160The electronic device 100 may not include at least one of the above-described elements or may further include any other element(s).

The bus 110 may interconnect the above-described elements 120 to 160 and may be a circuit for conveying communications (e.g., a control message and/or data) among the above-described elements.

The display 120 may output various content (e.g., a text, an image, a video, an icon, or a symbol) to a user. To this end, the display 120 may include a panel or a display driving circuit. According to embodiments, the display 120 may sense a touch or a touch gesture from the user. To this end, the display 120 may further include a touch panel 125. Various user interfaces (UIs) which are usable in embodiments of the present disclosure may be provided to the user through the display 120 and the touch panel 125.

The memory 130 may include a volatile and/or nonvolatile memory. The memory 130 may store various instructions, when executed, causing the processor 150 to perform an operation in response to the various instructions, as will be described later herein.

The memory 130 may store at least one video file 131, 132, or 133. In this disclosure, embodiments will be described on the basis of a video file. However, embodiments of this disclosure may not be limited thereto. For example, a file to which embodiments of this disclosure are applicable may include a media data file such as an image, audio, or text file.

FIG. 2 illustrates a video file according to an embodiment of the present disclosure.

Referring to FIG. 2, a video file 201 may include video data 211 and metadata 221. The video file 201 may correspond to any one of the video files 131 to 133.

The video data 211 may include a plurality of image data based on a number of frames and/or a plurality of audio data respectively corresponding to the plurality of image data. The video data 211 may be encoded according to a specified codec.

The metadata 221 may indicate information about properties of the video data 211. For example, the metadata 221 may include a variety of information about the video data 211 (or the video file 201), such as a title, a sub-title, a total playback time (or duration), a file generation time, resolution, an artist name, genre, and a used language.

According to an embodiment, the metadata 221 may further include bookmark information about a playback time point or a playback time interval specified by a user. That is, the bookmark information may not be generated as a separate file, but it may be included in the metadata 221 of the video file 201. Furthermore, the specified playback time point or playback time interval may be used as a preset playback time point or a bookmarked playback time point. According to embodiments, bookmark information may further include information about a playback speed set by a user in addition to the above-described information. When a video is played on the basis of the bookmark information, the playback speed information may be applied to the playback of the video.

Returning to FIG. 1, the communication circuit 140 may establish a communication with an external device based on a specified protocol. The electronic device 100 may send and receive data or a file through the communication circuit 140.

The processor 150 may be electrically connected with the display 120, the memory 130, the communication circuit 140, and the cache memory 160 of the electronic device 100. In addition to methods to be described below, the processor 150 may control the elements of the electronic device 100 or may perform various operations such as an operation associated with communication and a data processing operation.

According to an embodiment, the processor 150 may be configured to output a first preview (e.g., a preview video corresponding to an original video file, or an “original preview”) associated with video data of the original video file on the display 120. That is, the original preview may correspond to a preview associated with a total playback time of the video data of the original video file.

Furthermore, according to another embodiment, the processor 150 may be configured to output a second preview (e.g., a preview video corresponding to bookmark information, or a “bookmark preview”) based on metadata of the video file on the display 120. For example, the second preview may correspond to a preview associated with a bookmarked playback time point or a bookmarked playback time interval of the video data.

The original preview and/or the second preview may be an object that is capable of being generated by the processor 150 and is capable of being output on the display 120. For example, whenever the processor 150 searches for a video file from the memory 130, the processor 150 may generate the original preview and/or the second preview and may output the original preview and/or the second preview on the display 120. In this case, the processor 150 may store data associated with the original preview and/or the second preview in the cache memory 160 that is a high-speed volatile memory.

According to an embodiment, the original preview and/or the bookmark preview may include an image object (e.g., a thumbnail image object) or a video object (e.g., a thumbnail video object). In this disclosure, the image object may be referred to as a first-type object and the video object may be referred to as a second-type object.

The image object or the video object of the original preview may be extracted from at least a portion of a total playback time of video data. For example, the image object of the original preview may correspond to an object, which is based on a first frame image or a specified frame image of the video data. The video object of the original preview may be an object corresponding to a specified playback time interval (e.g., three seconds from a first frame of video data) of the video data or may correspond to an object sampled from frame images of the specified playback time interval.

The image object or the video object of the bookmark preview may be extracted from the bookmarked playback time point of the video data or from at least a portion of the bookmarked playback time interval of the video data. For example, the image object of the second preview may be based on a frame image of the bookmarked playback time point or a frame image of the starting time point of the bookmarked playback time interval. The video object of the second preview may be extracted from a specified playback time interval starting from the bookmarked playback time point or from a portion of the bookmarked playback time interval.

According to embodiments, the processor 150 may play video data of a video file stored in the memory 130 by using a multimedia player program. The video data of the played video file may be output on the display 120.

For example, if the original preview is selected according to a user input (e.g., a touch input received through the touch panel 125), the processor 150 may play video data from a predefined playback time point. In other words, if a first preview associated with video data of an original video file is selected, the processor 150 may play the video data of the original video file from the predefined playback time point with regard to a total playback time. The predefined playback time point may include a first playback time point of the video data or a playback time point at which the playback of the video data was previously ended.

If the bookmark preview is selected according to a user input, the processor 150 may play the video data of the original video file from a bookmarked playback time point or a starting time point of a bookmarked playback time interval. A starting playback time point and an implementation method when the second preview is selected may not be limited thereto.

The cache memory 160 may be operatively connected with the processor 150. According to an embodiment, the cache memory 160 may be a volatile memory and may be capable of processing data faster than the memory 130. The processor 150 may extract an object associated with the original preview and/or the second preview from the video files 131 to 133 stored in the memory 130 and may store data (e.g., data of an object included in a preview) associated with the previews in the cache memory 160. Whenever outputting a preview, the processor 150 may extract an object for the preview and may store the extracted object in a high-speed volatile memory (the cache memory 160). For this reason, the processor 150 does not need to extract the object in advance and store the extracted object in the memory 130.

FIG. 3 illustrates a bookmark setting method according to an embodiment of the present disclosure.

Referring to FIG. 3, a bookmark setting method will be described with reference to FIGS. 4A, 4B, 4C and 4D. In addition, since the electronic device 100 illustrated in FIG. 1 is capable of performing the operations of FIG. 3, the operations of FIG. 3 may use reference numerals of FIG. 1. Furthermore, the electronic device 100 of FIG. 1 may correspond to each of electronic devices 400a, 400b, and 400c of FIGS. 4A, 4B and 4C.

In operation 301, the electronic device 100 may play video data of a video file by executing a multimedia player application program.

FIG. 4A illustrates a bookmark setting method according to an embodiment of the present disclosure. A processor of the electronic device 400a may execute the multimedia player application program. If a preview of Video #1 (a video file) is selected according to a user input, as illustrated in FIG. 4A, predefined UI objects such as various soft keys and playback time axis, and a first frame image 421a of Video #1 may be output on a display 420a of the electronic device 400a. The electronic device 400a may receive a user input with respect to a playback button object 411a among the specified UI objects and may play video data of Video #1.

In operation 303 of FIG. 3, a user may select a first playback time point for a bookmark by using a UI object output on the display 120 of the electronic device 100 while video data of a video file is played.

Referring to FIG. 4B, a processor of the electronic device 400b may play the video data of Video #1. For example, a display 420b of the electronic device 400b may be outputting a frame image 421b at “00:00:43”. For example, when the playback time point of Video #1 is “00:00:43”, the user may select a bookmark button object 412b output on the display 420b. The processor of the electronic device 400b may recognize the playback time point at which the bookmark button object 412b is selected, that is, “00:00:43”, as a starting time point of a bookmark playback time interval (a first playback time point).

In operation 305 of FIG. 3, the user may select a second playback time point for the bookmark by using a UI object output on the display 120 of the electronic device 100 while the video data of the video file is played.

Referring to FIG. 4C, a processor of the electronic device 400c may continuously play back the video data of Video #1 . For example, a display 420c of the electronic device 400c may be outputting a frame image 421c at “00:01:13”. For example, when the playback time point of Video #1 is “00:01:13”, the user may select a bookmark button object 412c output on the display 420c. The processor of the electronic device 400c may recognize the playback time point at which the bookmark button object 412c is selected, that is, “00:01:13”, as an end time point of the bookmark playback time interval (a second playback time point).

In operation 307 of FIG. 3, the processor 150 of the electronic device 100 may write information about the playback time interval, which is an interval from the first playback time point to the second playback time point, in metadata of the video file that is being played as bookmark information. For example, since “00:00:43” is selected as the first playback time point in FIG. 4B and “00:01:13” is selected as the second playback time point in FIG. 4C, the playback time interval from “00:00:43” to “00:01:13” may be bookmarked. Information about the bookmarked playback time interval may be written in the metadata as bookmark information.

In operation 309, the processor 150 of the electronic device 100 may determine an object that is to be used when a bookmark preview of the playback time interval bookmarked in operation 307 is provided. According to embodiments, operation 309 may be omitted.

For example, since “00:00:43” is selected as the first playback time point in FIG. 4B and “00:01:13” is selected as the second playback time point in FIG. 4C, the frame image 421b of the first playback time point (“00:00:43”), which is the starting time point of the bookmarked playback time interval, may be determined as an image object 421d that will be included in a bookmark preview later (refer to FIG. 4D).

According to embodiments, FIG. 3 and FIGS. 4A, 4B, 4C and 4D are described under an assumption that bookmarking is made on a playback time interval. However, bookmarking can also be made on a certain playback time point. In this case, operation 305 may be omitted.

In the bookmark setting method according to an embodiment of the present disclosure described with reference to FIGS. 3, 4A, 4B, 4C and 4D, a separate bookmark file may not be generated because information about the bookmarked playback time interval is written in metadata. Accordingly, it is possible to prevent an unnecessary waste of computing/storage resources. Furthermore, it is possible for bookmarking to be made on a playback time interval as well as any playback time point.

FIG. 5 illustrates a video preview providing method according to an embodiment of the present disclosure.

Referring to FIG. 5, operations 501 to 515 may be performed after operations 301 to 309 of FIG. 3 are performed (e.g., after at least one bookmark preview is generated). For example, since the electronic device 100 illustrated in FIG. 1 is capable of performing the operations of FIG. 5, the operations of FIG. 5 may use reference numerals of FIG. 1.

In operation 501, the processor 150 of the electronic device 100 may execute a multimedia player application program. If the multimedia player application program is executed, the processor 150 may search for a video file from the memory 130. For example, the processor 150 may recognize that Video #1 (a video file) and Video #2 (a video file) are stored in the memory 130.

In operation 503, the processor 150 of the electronic device 100 may extract objects for a first preview and a second preview (a bookmark preview) from video data of the video files.

For example, the processor 150 of the electronic device 100 may extract and generate an image object or a video object for the original preview from at least a portion of a total playback time of the video data of each of Video #1 and Video #2.

The processor 150 of the electronic device 100 may extract and generate an image object or a video object for the bookmark preview, based on metadata of each of Video #1 and Video #2. For example, the processor 150 may extract and generate an image object or a video object for the bookmark preview from a bookmarked playback time point or at least a portion of a bookmarked playback time interval of the video data of each of Video #1 and Video #2.

In operation 505, the processor 150 of the electronic device 100 may store data associated with the original preview and the second preview in the cache memory 160. For example, the processor 150 may store data of the object for the original preview and data of the object for the bookmark preview extracted and generated in operation 503 in the cache memory 160.

In operation 507, the processor 150 of the electronic device 100 may output the original preview associated with the total playback time of the video data on the display 120.

In operation 509, the processor 150 of the electronic device 100 may output the bookmark preview associated with the bookmarked playback time point or the bookmarked playback time interval of the video data on the display 120.

With regard to operations 507 and 509, FIG. 6 illustrates an electronic device 600 on which a video preview according to an embodiment of this disclosure is displayed. Previews of Video #1 and Video #2 stored in the memory 130 are illustrated in a display 620 of the electronic device 600.

For example, a preview 601 illustrates an original preview related to the total playback time of the video data of Video #1. A preview 602 illustrates an original preview related to the total playback time of the video data of Video #2. Each of a preview 601-1 and a preview 601-2 illustrates a second bookmark preview that is based on the metadata of Video #1. A preview 602-1 illustrates a bookmark preview that is based on the metadata of Video #2. The bookmark previews 601-1, 601-2, and 602-1 may be associated with a bookmarked playback time point or a bookmarked playback time interval. Furthermore, an indication 611 (e.g., an icon, a badge, or a border) which indicates that the bookmark previews 601-1, 601-2, and 602-1 are bookmark previews may be added to each of the bookmark previews 601-1, 601-2, and 602-1 unlike the original previews 601 and 602.

In operation 511, the electronic device 100 may receive a user input (or selection). For example, the user input (e.g., a touch input, a gesture, or a voice input received through the touch panel 125) may correspond to the selection of a first preview or a second preview output in operation 507 and operation 509. For example, in FIG. 6, the user input may correspond to the selection of one of the original previews 601 and 602 or one of the bookmark previews 601-1, 601-2, and 602-1. If the user input is for selecting the original preview 601 or 602, the process proceeds to operation 513, whereas if the user input is for selecting the second preview 601-1, 601-2, or 602-1, the process proceeds to operation 515.

Since the user input for selecting the original preview is previously received, in operation 513, the processor 150 of the electronic device 100 may play video data from a predefined playback time point. In other words, since the original preview associated with video data of an original video file is selected, the processor 150 may play the video data of the original video file from the predefined playback time point of a total playback time. The predefined playback time point may include a first playback time point of the video data or a playback time point at which the playback of the video data was previously ended.

For example, in FIG. 6, if the original preview 602 is selected, a processor of the electronic device 600 may play video data of Video #2 from a first playback time point or a previously ended playback time point.

Since the user input for selecting the bookmark preview is previously received, in operation 515, the processor 150 of the electronic device 100 may play the video data from the playback time point bookmarked by the user. Furthermore, the processor 150 may play the video data from the playback starting time point of the bookmarked playback time interval to the playback end time point of the bookmarked playback time interval.

An embodiment is illustrated in FIG. 5 as the process ends after operations 513 or 515. However, embodiments may not be limited thereto. For example, the process may return to operation 511 to perform one of operations 513 or 515.

Furthermore, in operation 511, the user may modify bookmark information or an object included in the second preview by selecting the bookmark preview output on the display 120 in a specified manner. For example, in the case of FIG. 6, the user may access metadata of the original video file by performing a touch long press action with respect to any one of the bookmark previews 601-1, 601-2, and 602-1 output on the display 620. The user may modify the bookmarked playback time point or the bookmarked playback time interval by modifying the metadata.

FIG. 7 illustrates a method of sharing a video based on a bookmark preview, according to an embodiment of the present disclosure.

As described above, a bookmark preview may be generated based on bookmark information included in metadata of an original video file, and an object included in the bookmark preview may be extracted from video data of the original video file whenever the bookmark preview is generated. Therefore, a separate video file associated with a bookmarked playback time point or a bookmarked playback time interval may be needed to share a video associated with the bookmark preview with an external device, since the bookmark preview itself output on a display does not include video data content.

Referring to FIG. 7, operations 701 to 705 may be performed after operations 501 to 509 of FIG. 5 are performed. In addition, since the electronic device 100 of FIG. 1 is capable of performing the operations of FIG. 7, the reference numerals of FIG. 1 are used.

In operation 701, a user may select a bookmark preview output on the display 120 of the electronic device 100. For example, in FIG. 6, the user may select a bookmark preview to be shared by using a UI that is generated by performing a touch long press action with respect to any one of the bookmark previews 601-1, 601-2, and 602-1 output on the display 120.

In operation 703, the processor 150 of the electronic device 100 may generate a video file corresponding to a bookmarked playback time interval based on an original video file associated with the bookmark preview selected in operation 701. Alternatively, on the basis of the original video file, the processor 150 may generate a bookmark video file corresponding to an interval from the bookmarked playback time point to the end time point of a total playback time.

In operation 705, the processor 150 of the electronic device 100 may send the bookmark video file generated in operation 703 to an external device.

Furthermore, according to embodiments, the external device may store a video file which is the same as the original video file stored in the electronic device 100. In this case, the electronic device 100 may extract only bookmark information corresponding to the bookmark preview from metadata of the original video file and may send the extracted bookmark information (e.g., information about the bookmarked playback time point or the bookmarked playback time interval) to the external device. For example, the external device may add the bookmark information received from the external device 100 to metadata of the original video file, which is stored in advance. As such, the external device may provide the user with a bookmark preview which is the same as the bookmark preview of the electronic device 100.

According to embodiments of the present disclosure described above, a bookmark function may be provided without generating a separate file, by applying metadata included in a video file. Accordingly, it is possible to reduce computing/storage resources consumed to generate a separate bookmark file.

Furthermore, since the bookmark preview and the original preview are displayed together so as to be distinguished from each other, even though the original video is not played, a video corresponding to a bookmark may be more conveniently played by selecting the bookmark preview. In addition, if the bookmark preview output on the display is selected using a specified UI, it may be possible to easily modify a bookmarked playback time point or a bookmarked playback time interval and to share a bookmark video file with an external device.

According to an embodiment, an electronic device includes a memory that stores media data and a processor. The processor is configured to play the media data through a display operatively connected with the electronic device, to obtain an input while the media data is played, to generate bookmark information corresponding to at least a portion of the media data based at least on the input, and to include the bookmark information in the media data.

According to an embodiment, the processor may be configured to include the bookmark information in the media data as at least a portion of the media data and to store the media data including the bookmark information in the memory.

According to an embodiment, the processor may be configured to output an object of at least the portion of the media data corresponding to the bookmark information on the display.

According to an embodiment, the processor may be configured to output the object corresponding to the bookmark information as a first-type object on the display by using at least a portion of at least the portion of the media data if a playback time point of at least the portion of the media data corresponding to the bookmark information belongs to a first specified range and to output the object corresponding to the bookmark information as a second-type object on the display by using at least the portion of at least the portion of the media data if the playback time point of at least the portion of the media data corresponding to the bookmark information belongs to a second specified range.

According to an embodiment, the processor may be configured to generate a preview video corresponding to at least the portion of the media data based on at least a portion of the bookmark information.

According to an embodiment, the bookmark information may include a plurality of the bookmark information, and the preview video may include a video in which a plurality of at least partial media data respectively corresponding to the plurality of bookmark information are played in a playback time sequence.

For example, in FIG. 6, if the bookmark previews 601-1 and 601-2 (examples of the second preview) are linked to each other, preview that is arranged in a time sequence based on an order of playback time points may be generated. The generated preview may be output on a display instead of the original preview 601(an example of the first preview). That is, without separately generating the original preview 601, it is possible to configure a preview object that indicates the original video file, by using the bookmark previews 601-1 and 601-2.

In another example, when bookmark #1 (an image preview of a specified playback time point), bookmark #2 (a video preview for 1˜2 seconds of a total playback time) and bookmark #3 (a video preview for 2˜3 seconds of the total playback time) exist, the electronic device may configure an object associated with the original preview by using the plurality of bookmark information without generating a preview (e.g., the original preview 601) associated with the original video file.

According to an embodiment, if the bookmark information is included in the media data, the processor may be configured to display an indication on a portion of an object corresponding to the media data.

According to an embodiment, the processor may be configured to include the bookmark information in metadata corresponding to the media data.

According to an embodiment, the processor may be configured to send media data, in which the bookmark information is included, to an external electronic device such that at least the portion of the media data is provided by the external electronic device based at least in part on the bookmark information.

According to an embodiment, at least the portion of the media data may include first media data corresponding to a first range and second media data corresponding to a second range lagging behind the first range. The bookmark information may include first bookmark information corresponding to the first media data and second bookmark information corresponding to the second media data. The processor may be configured to assign a first priority to the first bookmark information and to assign a second priority to the second bookmark information.

For example, when the electronic device plays a video associated with the bookmark information by selecting at least one bookmark preview corresponding to bookmark information, the electronic device may play the video based on a priority included in the bookmark information. For example, the electronic device may utilize the order of the playback times as a reference for setting priority.

According to an embodiment, the processor may be configured to output the second media data before the first media data on the display based at least in part on the first priority or the second priority.

According to an embodiment, the processor may be configured to display first media data corresponding to first bookmark information and second media data corresponding to second bookmark information on the display, based at least on the first bookmark information corresponding to at least the portion of the media data and the second bookmark information corresponding to at least a portion of other media data.

For example, the processor of the electronic device may classify bookmark information based on the features of the bookmarked media data (e.g., a result of analyzing whether the media data is expressed with a figure or a background as the center) with reference to bookmark information of media data which are different from each other. The features of the media data may be included in bookmark information. Besides, the features of the media data may further include information that is obtained by analyzing a central figure or central content in the bookmarked playback time.

According to an embodiment, the processor may be configured to generate the bookmark information based at least on a playback history on the media data or any other media data.
