CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority of Chinese Patent Application No. 201810322229.5, filed on April 11, 2018, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure generally relates to data storage technology, and in particular, relates to systems and methods for storing multimedia resources.

BACKGROUND

In the digital age, various multimedia resources may be provided to people for meeting various needs, such as entertainment, work, etc. In some cases, the multimedia resources may be stored in a digital device. For example, videos and audios may be recorded by an automobile data recorder, videos, photos and audios may be recorded by a monitor, or by other home appliances via smart home application. During the data storage, a thread for storing the multimedia resource may be executed. Each thread may be independent. However, when multiple multimedia resources need to be stored at the same time, these multimedia resources may not have the same timestamp corresponding to the storage time, which may cause disorder when coming to synchronous synthesis of them. Therefore, it is desirable to develop systems and methods for storing the multiple multimedia resources so as to achieve the time synchronization of multimedia resource synthesis.

SUMMARY

According to an aspect of the present disclosure, a method is provided. The method may include one or more of the following operations. At least one processor may determine a time slice of the multimedia resource having a specified format in real time. The at least one processor may store the multimedia resource to a corresponding file based on a corresponding relation between the time slice and a preset time slice.

In some embodiments, the at least one processor may determine a plurality of preset time slices based on a time sequence, and store the plurality of preset time slices. Each of the plurality of preset time slices and the corresponding file may be named after a start time of the preset time slice.

In some embodiments, the at least one processor may determine whether the time slice of the multimedia resource matches the preset time slice. In response to a determination that the time slice of the multimedia resource does not match the preset time slice, the at least one processor may designate a name of the file storing the multimedia resource based on the time slice of the multimedia resource.

In some embodiments, the at least one processor may determine whether the time slice of the multimedia resource matches the preset time slice. In response to a determination that the time slice of the multimedia resource matches the preset time slice, the at least one processor may determine a time length between a start time of the time slice of the multimedia resource and a storage time, and store the multimedia resource to the corresponding file based on the time length.

In some embodiments, the at least one processor may determine whether the time length is greater than or equal to a duration of the preset time slice. In response to a determination that the time length is greater than or equal to the duration of the preset time slice, the at least one processor may store the multimedia resource to a file corresponding to a second preset time slice. The second preset time slice may be a next time slice adjacent to the preset time slice. In response to a determination that the time length is less than the duration of the preset time slice, the at least one processor may store the multimedia resource to the corresponding file corresponding to the preset time slice.

In some embodiments, the at least one processor may start a thread synchronization lock. The at least one processor may subsequently designate the storage time of the multimedia resource as the name of the second preset time slice, and designate the name of the second preset time slice as the name of the file.

In some embodiments, the multimedia resource may include at least one of a digital image format, an audio format, or a video format.

According to another aspect of the present disclosure, a system is provided. The system may include at least one storage device, at least one processor in communication with the at least one storage device. The at least one storage device may include one or more sets of instructions. When executing the one or more sets of instructions, the at least one processor may determine a time slice of the multimedia resource having a specified format in real time, and store the multimedia resource to a corresponding file based on a corresponding relation between the time slice and a preset time slice.

According to another aspect of the present disclosure, a device is provided. The device may at least include a determination unit for determining a time slice of the multimedia resource having a specified format in real time, and a storing unit for storing the multimedia resource to a corresponding file based on a corresponding relation between the time slice and a preset time slice.

According to another aspect of the present disclosure, a non-transitory computer readable medium is provided. The non-transitory computer readable medium may comprise executable instructions that cause at least one processor to effectuate a method. The method may include one or more of the following operations. At least one processor may determine a time slice of the multimedia resource having a specified format in real time. The at least one processor may store the multimedia resource to a corresponding file based on a corresponding relation between the time slice and a preset time slice.

It is to be expressly understood, however, that the drawing (s) are for the purpose of illustration and description only and are not intended to limit the scope of the present disclosure. It is understood that the drawings are not to scale.

The flowcharts used in the present disclosure illustrate operations that systems implement according to some embodiments of the present disclosure. It is to be expressly understood, the operations of the flowcharts may be implemented not in order. Conversely, the operations may be implemented in inverted order, or simultaneously. Moreover, one or more other operations may be added to the flowcharts. One or more operations may be removed from the flowcharts.

FIG. 1 is a flowchart illustrating an exemplary process for storing multimedia resources according to some embodiments of the present disclosure. In some embodiments, process 100 for storing the multimedia resources may be implemented by a multimedia resource storing device (e.g., a multimedia resource storing device 200 shown in FIG. 2) . In some embodiments, the process 100 may also be implemented as one or more instructions stored in a storage medium and called and/or executed by a processor (e.g., a processor of the multimedia resource storing device 200) . The operations of the illustrated process presented below are intended to be illustrative. In some embodiments, the process 100 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 100 as illustrated in FIG. 1 and described below is not intended to be limiting.

In 102, during storing the multimedia resource, the processor may determine a time slice of the multimedia resource having a specified format in real time.

In some embodiments, the specified format may include but not limited to a digital image format, an audio format, or a video format. Exemplary digital image format may include bmp, jpg, png, tiff, gif, pcx, tga, exif, fpx, fvg, ps, or the like, or any combination thereof. Exemplary audio file format may include CD, WAVE, AIFF, AU, MP3, MIDI, WAM, RealAudio, VQF, OggVorbits, AAC, AP, or the like, or any combination thereof. Exemplary video file format may include MPEG, MPG, DAT, MP4, or the like, or any combination thereof.

In 104, the processor may store the multimedia resource to a corresponding file based on a corresponding relation between the time slice and a preset time slice.

In some embodiments, during the storing the multimedia resource in real time, multiple multimedia resources need to be synchronized based on the time slice (s) . The time slice may be designated as a timestamp associated with the multimedia resource to be stored. The processor may store the multimedia resource to a corresponding file associated with the time slice and/or the timestamp. Specifically, the processor may store the multimedia resource to the corresponding file based on a relation between the time slice and the preset time slice. Merely for illustration, assuming that a camera needs to record an audio resource A and a video resource B synchronously, the time slice of both audio resource A and video resource B are recorded as T1 which corresponds to the preset time slice T1. The processor may store the audio resource A and the video resource B to the file corresponding to the preset time slice T1, respectively. In some embodiments, the processor may further synthesize the audio resource A and the video resource B stored in the file corresponding to the preset time slice T1 so as to keep time synchronization of the audio resource A and the video resource B.

For example, let the start time of the N-th time slice be t _N, where N is a positive integer that is greater than or equal to 1. The time length of the time slice is d. The start time may be designated as the name of the N-th time slice, that is t _N. In some embodiments, because the multimedia resource may be stored in accordance with each time slice, the timestamp of the multimedia resource may also be determined as t _N if the current time slice of the multimedia resource corresponds to the time slice t _N.

It may be beneficial to improve synthetic accuracy of the multiple multimedia resources based on the determined time slice in real time which each of multiple multimedia resources belongs to. The multiple multimedia resources may include the audio resources, the video resources, the picture resources, or the like, or any combination thereof. In some embodiments, in the process of synthesizing the multiple multimedia resources, the processor may designate the time slice corresponding to each multimedia resource as the timestamp of the each resource. The processor may further synthesize the multiple multimedia resources that have the same timestamp so as to achieve the time synchronization of multimedia resource synthesis.

In some embodiments, prior to the storing the multimedia resource, the processor may determine a plurality of preset time slices based on a time sequence (e.g., the preset time slice 410 as shown in FIG. 4) . For example, 10:00～10: 30 may be preset as a first preset time slice, 10: 30～11: 00 may be preset as a second preset time slice. The processor may store the plurality of preset time slices to the storage medium (e.g., the computer storing device 300) . In some embodiments, each of the plurality of preset time slices may be named after the start time of the preset time slice. In some embodiments, the corresponding file of each preset time slice may also be named after the start time of the preset time slice.

In some embodiments, the plurality of preset time slices may correspond to the time slices associated with the files that are used to store the multimedia resources. Each of the plurality of preset time slices may be named after the start time of the preset time slices, and arranged in the time sequence. In some embodiments, the preset time slice may include a preset time duration of the preset time slice (e.g., the time duration L illustrated in FIG. 4) . In some embodiments, the processor may generate a plurality of files for storing the multimedia resource that satisfies the preset time slice. The corresponding file may be named after the start time of the preset time slice.

For example, let the start time of the N-th preset time slice be T _N, where N is a positive integer that is greater than or equal to 1. The time duration of the preset time slice T _N is L. The name of the preset time slice may be denoted as T _N. If a time slice of the multimedia resource to be stored satisfies the preset time slice T _N, that is, the start time of the time slice of the multimedia resource is T _N, the processor may store the multimedia resource to the corresponding file that is named after the start time of the preset time slice. In other words, the name of the corresponding file for storing the multimedia resource is also designated as T _N.

In some embodiments, the processor may determine whether the time slice of the multimedia resource matches the preset time slice. In response to a determination that the time slice of the multimedia resource does not match the preset time slice, the processor may designate the name of the file storing the multimedia resource based on the time slice of the multimedia resource. Merely for illustration, when the start time of the time slice of the multimedia resource is not the same as the start time of the preset time slice, the processor determines that the time slice of the multimedia resource does not match the preset time slice. In the case, the processor may designate the start time of the time slice of the multimedia resource, i.e., the start time of the time slice of to which the multimedia resource belonging, as the name of the file storing the multimedia resource. Thus, the name of the corresponding storage file may correspond to the time slice of the multimedia resource, and be a timestamp for storing the multimedia resource. To guarantee the time synchronization of the multimedia resources when the processor synthesizes multiple multimedia resources, the processor may synthesize the multimedia resources that are stored in the files having the same name. It should be understood that the same file name may indicate the multimedia resources having the same time slice and/or timestamp.

In some embodiments, when the start time of the time slice of the multimedia resource is the same as the start time of the preset time slice, the processor determines that the time slice of the multimedia resource matches the preset time slice. In response to the determination that the time slice of the multimedia resource matches the preset time slice, the processor may determine a time length between the start time of the time slice of the multimedia resource and a storage time. The storage time may refer to the time when the processor decides to store the multimedia resource. The processor may further store the multimedia resource to the corresponding file based on the time length to improve the synchronization of multimedia resource synthesis.

Specifically, the processor may determine whether the time length is greater than or equal to a duration of the preset time slice. In response to the determination that the time length is greater than or equal to the duration of the preset time slice, the processor may store the multimedia resource to a file corresponding to a second preset time slice. The second preset time slice may be a next time slice adjacent to the preset time slice. In response to a determination that the time length is less than the duration of the preset time slice, the processor may store the multimedia resource to the corresponding file corresponding to the preset time slice.

For example, assuming that the time length of the time slice of the current multimedia resource is d1, and the time length of a first preset time slice is L1. The start time of both the time slice of the current multimedia resource and the first preset time slice are the same. In other words, the processor may determine that the time slice of the multimedia resource matches the first preset time slice. If d1 is less than L1, in this case, the storage space of the first file corresponding to the first preset time slice may be enough to store the current multimedia resource. The processor may store the current multimedia resource to the first file corresponding to the first preset time slice. The name of the first preset time slice, that is, the start time of the first preset time slice, may be designated as the name of the first file. If d1 is greater than or equal to L1, in this case, the storage space of the first file corresponding to the first preset time slice may be not enough to store the current multimedia resource. The processor may need the second file to store the multimedia resource. The second file may refer to a file corresponding to the second preset time slice, and the second preset time slice may be the next time slice adjacent to the first preset time slice.

In some embodiments, in the process of storing the multimedia resource to the second file corresponding to the second preset time slice, the processor may start a thread synchronization lock. The processor may subsequently designate the storage time of the multimedia resource as the name of the second preset time slice. In some embodiments, the storage time may be different from the start time of the second preset time slice. The processor may modify the name of second preset time slice from the original start time to the current storage time. In some embodiments, the processor may further designate the name of the second preset time slice as the name of the second file, that is, the storage time. The multimedia resource may be stored to the second file. It should be understood that the thread synchronization lock may reduce a conflict of the data storage thread.

In some embodiments, the processor may further synthesize the multiple multimedia resources having the same timestamp, which may achieve the time synchronization of multimedia resource synthesis. For example, the processor may obtain the multiple multimedia resources from one or more files having the same name, and synthesize the one or more multimedia resources.

FIG. 2 is a block diagram illustrating an exemplary device for storing multimedia resources according to some embodiments of the present disclosure. As shown in FIG. 2, multimedia resource storing device 200 may include at least one processing device to perform exemplary processes or methods described in the present disclosure (e.g., the process 100 illustrated in FIG. 1) . In some embodiments, the at least one processing device may be in communication with a computer-readable storage medium and may execute instructions stored in the computer-readable storage medium to perform the exemplary processes or methods described in the present disclosure (e.g., the process 100 illustrated in FIG. 1) . In some embodiments, the computer-readable storage medium may be integrated to the multimedia resource storing device 200. In some embodiments, the computer-readable storage medium may separate from the multimedia resource storing device 200. As shown in FIG. 2, the multimedia resource storing device 200 may include the at least one processing device including a determination unit 202, a storing unit 204, a judging unit 206, a computing unit 208, and a controlling unit 210.

In some embodiments, the determination unit 202 may be configured to determine a time slice of the multimedia resource having a specified format in real time during the storing of the multimedia resource.

In some embodiments, the storing unit 204 may be configured to store the multimedia resource to a corresponding file based on a corresponding relation between the time slice and a preset time slice.

In some embodiments, during the storing the multimedia resource in real time, multiple multimedia resources need to be synchronized based on the time slice (s) . The time slice may be designated as a timestamp associated with the multimedia resource to be stored. The processor may store the multimedia resource to a corresponding file associated with the time slice. Specifically, the processor may store the multimedia resource to the corresponding file based on a relation between the time slice and a preset time slice.

For example, let the start time of the N-th time slice be t _N, where N is a positive integer that is greater than or equal to 1. The time length of the time slice is d. The start time may be designated as the name of the N-th time slice, that is t _N. In some embodiments, because the multimedia resource may be stored in accordance with each time slice, a timestamp of the multimedia resource may be determined as t _N if current time slice of the multimedia resource corresponds to the time slice t _N.

It may be beneficial to improve synthetic accuracy of the multiple multimedia resources based on the determined time slice to which each of the multiple multimedia resources belongs. The multiple multimedia resources may include the audio resources, the video resources, the picture resources, or the like, or any combination thereof. For example, in the process of synthesizing the multiple multimedia resources, the processor may designate the time slice corresponding to each multimedia resource as the timestamp of the each resource. The processor may further synthesize the multiple multimedia resources that have the same timestamp so as to achieve the time synchronization of multimedia resource synthesis.

In some embodiments, the storing unit 204 may be further configured to determine a plurality of preset time slices based on a time sequence (e.g., the preset time slice 410 as shown in FIG. 4) . For example, 10: 00～10: 30 may be preset as a first preset time slice, 10: 30～11: 00 may be preset as a second preset time slice The storing unit 204 may store the plurality of preset time slices to a storage medium (e.g., the computer storing device 300) . In some embodiments, each of the plurality of preset time slices may be named after the start time of the preset time slice. In some embodiments, the corresponding file of each preset time slices may also be named after the start time of the preset time slice.

For example, assuming that the start time of the N-th preset time slice is T _N, where N is a positive integer that is greater than or equal to 1. The time duration of the preset time slice T _N is L. The name of the preset time slice may be denoted as T _N. If a time slice of the multimedia resource to be stored satisfies the preset time slice T _N, that is, the start time of the time slice of the multimedia resource is T _N, the processor may store the multimedia resource to the corresponding file that is named after the start time of the preset time slice. In other words, the name of the corresponding file for storing the multimedia resource is also designated as T _N.

In some embodiments, the judging unit 206 may be configured to determine whether the time slice of the multimedia resource matches the preset time slice. In response to a determination that the time slice of the multimedia resource does not match the preset time slice, the determination unit 202 may designate the name of the file storing the multimedia resource based on the time slice of the multimedia resource. Merely for illustration, when the start time of the time slice of the multimedia resource is not the same as the start time of the preset time slice, the judging unit 206 determines that the time slice of the multimedia resource does not match the preset time slice. In the case, the determination unit 202 may designate the start time of the time slice of the multimedia resource, i.e., the start time of the time slice of to which the multimedia resource belonging, as the name of the file storing the multimedia resource. Thus, the name of the corresponding storage file may correspond to the time slice of the multimedia resource, and be a timestamp for storing the multimedia resource. To guarantee the time synchronization of multimedia resources when the processor synthesizes multiple multimedia resources, a processor may synthesize the multimedia resources that are stored in the files having the same name. It should be understood that the same file name may indicate the multimedia resources having the same time slice and/or timestamp.

In some embodiments, when the start time of the time slice of the multimedia resource is the same as the start time of the preset time slice, the judging unit 206 determines that the time slice of the multimedia resource matches the preset time slice. In response to the determination that the time slice of the multimedia resource matches the preset time slice, the computing unit 208 may be further configured to determine a time length between the start time of the time slice of the multimedia resource and a storage time. The storage time may refer to the time when the processor decides to store the multimedia resource. The storing unit 204 may further store the multimedia resource to the corresponding file based on the time length to improve the synchronization of multimedia resource synthesis.

Specifically, the judging unit 206 may determine whether the time length is greater than or equal to a duration of the preset time slice. In response to the determination that the time length is greater than or equal to the duration of the preset time slice, the storing unit 204 may store the multimedia resource to a file corresponding to a second preset time slice. The second preset time slice may be a next time slice adjacent to the preset time slice. In response to a determination that the time length is less than the duration of the preset time slice, the storing unit 204 may store the multimedia resource to the corresponding file corresponding to the preset time slice.

For example, assuming that the time length of the time slice of the current multimedia resource is d1, and the time length of a first preset time slice is L1. The start time of both the time slice of the current multimedia resource and the first preset time slice are the same. In other words, the judging unit 206 may determine that the time slice of the multimedia resource matches the first preset time slice. If d1 is less than L1, in this case, the storage space of the first file corresponding to the first preset time slice may be enough to store the current multimedia resource. The storing unit 204 may store the current multimedia resource to the first file corresponding to the first preset time slice. The name of the first preset time slice, that is, the start time of the first preset time slice, may be designated as the name of the first file. If d1 is greater than or equal to L1, in this case, the storage space of the first file corresponding to the first preset time slice may be not enough to store the current multimedia resource. The storing unit 204 may need the second file to store the multimedia resource. The second file may refer to a file corresponding to the second preset time slice, and the second preset time slice may be the next time slice adjacent to the first preset time slice.

In some embodiments, in the process of storing the multimedia resource to the second file corresponding to the second preset time slice, the controlling unit 210 may start a thread synchronization lock. The determination unit 202 may subsequently designate the storage time of the multimedia resource as the name of the second preset time slice. In some embodiments, the storage time may be different from the start time of the second preset time slice. The determination unit 202 may modify the name of second preset time slice from the original start time to the current storage time. In some embodiments, the determination unit 202 may further designate the name of the second preset time slice as the name of the second file, that is, the storage time. The multimedia resource may be stored to the second file. It should be understood that the thread synchronization lock may reduce a conflict of the data storage thread.

It should be noted that the descriptions above in relation to the at least one processing device is provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. For example, the judging unit 206 and the computing unit 208 may be integrated to a single unit. However, those variations and modifications do not depart the scope of the present disclosure.

FIG. 3 is a block diagram illustrating an exemplary storage device according to some embodiments of the present disclosure. As shown in FIG. 3, a computer storing device 300 may at least include the multimedia resource storing device 200 illustrated in FIG. 2. In some embodiments, the determination unit 202, the storing unit 204, the judging unit 206, the computing unit 208, and the controlling unit 210 in the multimedia resource storing device 200 may include at least one of a central processor unit (CPU) , a digital signal processor (DSP) , a programmable logic controller (PLC) , or the like, or any combination thereof. The computer storage device 300 may be configured to process the multimedia resources, such as, recording, synthesizing, or playing the multimedia resources.

FIG. 4 is a schematic diagram illustrating an exemplary scheme for storing multimedia resources according to some embodiments of the present disclosure. As shown in FIG. 4, reference numeral 410 denotes a plurality of preset time slices. As described in connection with FIG. 2, the storing unit 204 generates and stores the plurality of preset time slices based on a time sequence. For example, the start time of the N-th preset time slice may be T _N, where N is a positive integer that is greater than or equal to 1. The time duration of the preset time slice may be equal to L. The preset time slice may be named after the start time of the preset time slice itself, such as, T ₁, T ₂, …, T _N. In some embodiments, the time duration of each of the plurality of the preset time slices 410 may be equal, or the time duration of a portion of the plurality of the preset time slices 410 may be equal.

In some embodiments, during storing the multimedia resources, each multimedia resource may be loaded to a single thread operation. For example, as shown in FIG. 4, reference numeral 420 denotes an audio resource, reference numeral 430 denotes a video resource. The audio resource 420 may be load to a first thread for storing the audio resource, and the video resource 430 may be load to a second thread for storing the video resource. In some embodiments, the first thread may be independent from the second thread.

Merely for illustration, during storing audio resource, the audio resource 420 may be divided to a plurality of time slices, such as, t ₁₁, t ₁₂, …, t _1N. In some embodiments, each time slice may be named after its own start time. The time length of the time slice regarding the audio resource 420 may be equal to d. The processor may determine whether the time slice of the audio resource 420 matches a preset time slice. In some embodiments, if the time slice of the audio resource does not match the preset time slice, for example, t ₁₁ is not the same as T ₁, the processor may store the audio resource corresponding to the time slice t ₁₁ to a first file. The first file may be named after the start time of the time slice t ₁₁, that is, t ₁₁. Similarly, the processor may store the audio resources associated with other time slices to corresponding files. In some embodiments, if the time slice of the audio resource 420 matches the preset time slice, for example, t ₁₁ is the same as T ₁, the processor may further determine whether the time length of the time slice (i.e., d) is greater than or equal to the duration of the preset time slice (i.e., L) . If d is less than L, the processor may store the audio resource corresponding to the time slice t ₁₁ to a file corresponding to the preset time slice T ₁. If d is equal to or less than L, the processor may store the audio resource corresponding to the time slice t ₁₁ to a file associated with the next time slice adjacent to the first preset time slice (e.g., the file corresponding to the preset time slice T ₂) .

Similarly, during storing the video resource 430, the video resource 430 may be divided to a plurality of time slices, such as, t ₂₁, t ₂₂, …, t _2N. The processor may store the video resource 430 corresponding to each of the plurality of time slices to the corresponding file based on the relation of the time slice and the preset time slice.

In some embodiments, the plurality of preset time slices 410 may be preset. The duration of each preset time slice may be preset as an equal time length, L. During storing the audio resource 420 and the video resource 430 at the same time, the audio resource 420 and the video resource 430 may be divided to the plurality of time slices respectively based on the plurality of preset time slices. Merely for illustration, the audio resource 420 may be divided to the first plurality of time slices that are the same as the plurality of preset time slices. For instance, the start time of the time slice t ₁₁ is the same as the start time of the preset time slice T ₁, and the time length of the time slice t ₁₁ is equal to the duration of the preset time slice T ₁, that is, d=L. Each of the first plurality of time slices of the audio resource 420 corresponds to the preset time slice 410. Similarly, the video resource 430 may be divided to the second plurality of time slices that correspond to the plurality of preset time slices 410. Each of the second plurality of time slices of the video resource 430 corresponds to the preset time slice 410. The audio resource 420 and the video resource 430 may be stored to the file corresponding to the preset time slice respectively. In some embodiments, the audio resource 420 and the video resource 430 may be synthesized based on the time slice which the audio resource and the video resource belongs to. For example, the processor may synthesize the audio resource 420 and the video resource 430 that belong to the same time slice so as to achieve the time synchronization of multimedia resource synthesis.
