Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a multimedia data storage method and device, a storage medium and electronic equipment. Any kind of multimedia data storage device provided by the embodiment of the application can be integrated in electronic equipment, and the electronic equipment can comprise a mobile terminal, a PC (personal computer) terminal, wearable equipment, a robot and the like. The electronic device includes a memory therein, which may be used to store multimedia data.
Referring to fig. 1, fig. 1 is a schematic flow chart of a multimedia data storage method provided in an embodiment of the present application, which is applied to an electronic device, and the multimedia data storage method includes steps 101 to 104, which may specifically be as follows:
101, when receiving a multimedia data storage instruction, acquiring multimedia data carried in the multimedia data storage instruction.
The multimedia data includes information expressed in text, image, video, audio, animation, and the like. The multimedia data storage instruction can be triggered in various ways. For example, the storage control may be triggered by clicking/touching the storage control, where the storage control may exist in the form of a button (e.g., a save button, a download button, a favorite button, etc.), an icon, a label, a text, or a combination of the above-mentioned forms, such as a combination of text and a button, a combination of an icon and text and a button, etc. And when the user is detected to click/touch the storage control, triggering a multimedia data storage instruction. The multimedia data storage instruction can be triggered in a voice mode, for example, the voice information of a user is received, the voice information is analyzed, and if the voice information comprises the content triggering the storage of the multimedia data, the multimedia data storage instruction is triggered. The multimedia data storage command may also be triggered by a command, for example, a multimedia data storage command, such as savexxx. Triggering in other related events can be executed, for example, when a user takes a picture, a picture storage instruction can be triggered after the picture taking is finished; when receiving pictures or videos and the like sent by other electronic equipment, the multimedia data storage instruction is triggered. After the multimedia data storage instruction is triggered, the electronic device receives the multimedia data storage instruction.
The multimedia data storage instruction carries multimedia data, and when the multimedia data storage instruction is received, the multimedia data carried in the multimedia data storage instruction is obtained. For example, when a multimedia data storage instruction is triggered by a command, xxx.png in the multimedia data storage instruction save xxx.png is obtained.
As shown in fig. 2, opening a picture in the electronic device, clicking/touching the picture, a plurality of option controls appear: sending to friends, saving pictures, editing pictures, canceling, etc. And clicking/touching the storage control for storing the picture, and triggering a multimedia data storage instruction. And after the multimedia data storage instruction is triggered, the electronic equipment receives the multimedia data storage instruction.
And 102, dividing the multimedia data into n data blocks, wherein n is a natural number which is more than or equal to 2.
The multimedia data is divided into n data blocks, which may be divided in a variety of ways.
The multimedia data can be divided according to the size of the multimedia data, and the number of divided data blocks is large if the multimedia data is large; and if the multimedia data is small, the number of the divided data blocks is small. Thus, if the multimedia data is large, a plurality of storage units are used for storage, and if the multimedia data is small, a small number of storage units are used for storage. Specifically, the size of the acquired multimedia data may be divided into a plurality of different sections, and the number of data blocks corresponding to the different sections is different, so as to acquire the size of the multimedia data, determine which section the acquired multimedia data is in, and determine the number of data blocks that the acquired multimedia data needs to be divided into according to the correspondence between the sections and the number of data blocks. In this type of division, the number of data blocks divided by different multimedia data to be stored is different. For example, a picture is divided into 2 data blocks, a video is divided into 5 data blocks, and so on.
The division may also be made according to the storage space of the memory. For example, the total storage space of the memory is obtained; the larger the total storage space is, the larger the number of divided data blocks is, and the larger the total storage space is, the smaller the number of divided data blocks is. Specifically, the corresponding relation between the total storage space of the memory and the number of the divided data blocks is determined, and the number of the data blocks to be divided is determined according to the obtained total storage space of the memory and the corresponding relation. Or acquiring the residual storage space of the storage; the larger the remaining storage space is, the larger the number of divided data blocks is, and the larger the remaining storage space is, the smaller the number of divided data blocks is. Specifically, the corresponding relation between the remaining storage space of the memory and the number of the divided data blocks is determined, and the number of the data blocks to be divided is determined according to the acquired remaining storage space of the memory and the corresponding relation. In this division mode, the number of data blocks divided by the multimedia data is related to the size of the storage space of the memory.
There is also a way of dividing into n data blocks regardless of the size of the multimedia data, i.e., dividing into n data blocks per multimedia data.
The number of divided data blocks corresponding to the data type of each different multimedia data may also be preset. The data types include pictures, files, character strings, sounds, videos, and the like. The number of the divided data blocks corresponding to different data types may be the same or different. After the multimedia data are obtained, the data type of the multimedia data is determined, and the number of data blocks to be divided is determined according to the data type. The data type of the multimedia data can be determined according to the file name of the multimedia data, and if suffixes in the file name are jpg, png and the like, the data type of the multimedia data is determined to be a picture.
The division may also be performed in other ways. It should be noted that the above-mentioned dividing manners can be combined in various ways to determine the number of data blocks for dividing the multimedia data.
After the number of data blocks corresponding to the divided multimedia data is determined, various ways can be adopted for dividing each data block. For example, the multimedia data is equally divided into n data blocks, and the sizes of the n data blocks are consistent; the division may also be performed according to a predetermined rule, for example, the size of the data blocks is divided in the order from small to large, in the order from large to small, in the order of one large and one small immediately after one large and one small, in a preset ratio, and the like.
Whatever the division method, the division can be performed by dividing the data block into a plurality of data blocks.
103, determining n storage units in the electronic device memory.
Wherein the number of data blocks divided by the multimedia data is consistent with the determined number of storage units.
In particular, the n memory locations in the memory of the electronic device are determined, which may also be determined in a variety of ways.
If the data type of the multimedia data can be obtained, n storage units in the electronic equipment memory are determined according to the data type of the multimedia data. For example, if the data type is video, n storage units with large remaining storage space (e.g., determined according to the remaining storage space being larger than a preset threshold value; or determined according to the sequence of the remaining storage space from large to small, etc.) are determined from the storage units storing data in the electronic device memory, and the n storage units can store data blocks of the video; or n memory cells are determined from memory cells in the electronic device memory that do not store data. As can be appreciated, the video has a large amount of data to store, and requires a large storage space to store. If the data type is a picture, n storage units with small remaining storage space (determined in a certain storage space interval according to the remaining storage space) are determined from the storage units of the stored data of the electronic equipment, and if the number of the storage units of the stored data is less than n, the remaining storage units are determined from the storage units of the stored data. It will be appreciated that the pictures can be stored using less storage space.
If the size of the divided data block can be obtained, n storage units in the electronic device memory are determined according to the size of the divided data block. For example, memory cells having a remaining memory space greater than or equal to the size of the divided data blocks are determined from memory cells in which data has been stored in the memory of the electronic device, and if the determined number of memory cells is less than n, the remaining number of memory cells are determined from memory cells in which data has not been stored. Therefore, the determined storage unit can complete the storage of the multimedia data.
Wherein determining the remaining number of memory cells from the memory cells that do not store data comprises: determining the residual storage units which are detected in advance and do not store any data from the storage units which do not store data, or determining the residual storage units which are closest to the storage units which store data and do not store any data from the storage units which do not store data, and the like. Therefore, the utilization rate of the memory is improved, and the stored data is convenient to read from the determined memory cells.
The n memory cells may also be determined in other ways. In any way, the number of data blocks divided by the multimedia data is ensured to be consistent with the determined number of storage units.
And 104, respectively storing the n data blocks into n storage units through pulse signals.
The pulse signal is a discrete signal, and the information of the data block is stored through the pulse signal. Signals that are not continuous in time but are still continuous in amplitude are referred to herein as discrete signals. Analog signals are signals in which the information parameter appears as a continuous signal in a given range, or signals in which the characteristic quantity representing the information can be represented as any value at any instant in a continuous time interval. It should be noted that the information of the data block is stored by the pulse signal (a kind of discrete signal) because the analog signal cannot be used for storage, the electronic device recognizes the digital signals such as 0 and 1, the current memory actually stores the information in different combinations of 0 and 1, and therefore, the analog signal cannot be used for storage in the electronic device, and the discrete signal can be stored in the electronic device. In the present application, the burst signal is used to store multimedia data, and thus may also be referred to as a burst storage signal.
Specifically, step 104 includes: generating a pulse storage signal, the pulse storage signal comprising n storage pulses; loading n data blocks to n storage pulses to obtain n loading storage pulses; and storing the n load-store pulses into the n storage units respectively.
Wherein generating a pulsed stored signal comprises: acquiring the size of a storage space of a storage unit of a memory and the size of a data block; determining the amplitude and width of a storage pulse according to the size of the storage space and the size of the data block; a pulse storage signal is generated based on the storage pulse amplitude and the storage pulse width.
If the sizes of the memories are different, the storage spaces of the corresponding storage units may also be different, the size of the storage space of the storage unit of the memory and the size of the data block are obtained, and the storage pulse amplitude and the storage pulse width are determined according to the size of the storage space and the size of the data block. Wherein, the larger the amplitude of the storage pulse is, the more energy can be carried, and the more data can be stored; the larger the storage pulse width, the larger the amount of data that can be stored. If the storage pulse amplitude is too large or the storage pulse width is too wide, and the amount of stored data is larger than that of the storage space of the storage unit, the storage cannot be realized. The storage pulse width and the storage pulse amplitude are such that the amount of data corresponding to the data block can be stored.
Wherein, the storage pulse amplitude is 1.0V (n) is less than or equal to 1.8V, and the storage pulse width t is less than 600 us. A pulse storage signal is generated based on the storage pulse amplitude and the storage pulse width. The pulse storage signal may be represented by f1(n) ═ f1(± 2), f1(± 3),. and f1(± n)), where | n | ≧ 2 a natural number, and n ≧ 2, ± 3.
And loading the n data blocks to the n storage pulses to obtain n loading storage pulses, namely continuously and uninterruptedly loading the n data blocks corresponding to the multimedia data to the n storage pulses of the pulse storage signal f1(n) to obtain n loading storage pulses. The n load store pulses are stored in the n storage units, respectively, and it can be understood that n data blocks are stored by the n store pulses, and the load store pulses in which the n data blocks are stored in the n storage units, respectively. Thus, stored in the memory cell is a load store pulse in which information of the corresponding data block is loaded.
After n data blocks of the multimedia data are stored in n storage units through pulse signals, the corresponding relation between the multimedia data and the storage units is stored, so that the multimedia data can be further processed conveniently, such as viewing, editing and the like.
The multimedia data are loaded through the pulse signals, and the pulse signals loaded with the multimedia data are stored instead of directly storing the digital information of the multimedia data in the storage unit, so that the original storage mode of the data is changed. The multimedia data are stored through the pulse signals, more data can be stored, the storage space for storing the multimedia data is reduced, and the storable data of the memory of the electronic equipment is increased. In addition, the multimedia data divided into n data blocks are respectively stored into n storage units through pulse signals, and the pulse signals for storing one multimedia data are integrally output. When the multimedia data is started, the pulse signal is started integrally, and when the multimedia data is transmitted integrally, the situation that part of multimedia data is deleted by mistake cannot exist, so that the part of the multimedia data is prevented from being deleted by mistake; meanwhile, the situation of losing part of the multimedia data is not possible during transmission, and the loss of part of the multimedia data during transmission is avoided.
In some cases, as shown in FIG. 3, the multimedia data storage method further comprises the following steps 105-106:
105, when the multimedia data opening instruction is received, acquiring the target multimedia data carried in the multimedia data opening instruction.
The multimedia data open command may also be triggered in various ways, please refer to the above-mentioned part of the multimedia data storage command.

And acquiring a pulse storage signal from a target storage unit of the electronic equipment memory, and opening the pulse storage signal to open the target multimedia data. It should be noted that n storage pulses in the pulse storage signal are not increased or decreased, and the n storage pulses are output as a whole.

For a memory, the storage space of the storage unit of the memory is certain, and whether the storage space of the storage unit of the memory is completely used or not is detected and can be determined according to the data amount currently stored in the storage unit of the memory. And if the stored data amount reaches the storage amount corresponding to the storage space of the storage unit, determining that the storage space of the storage unit is completely used. It should be noted that the storage space of the storage unit is fully used, which means that the storage unit cannot store more data.

It will be appreciated that if the storage space of k storage units is already fully used, then k storage units are determined from the electronic device memory, thus ensuring that there are n storage units for storing multimedia data. The manner in which the k memory cells are determined from the electronic device memory is consistent with the manner in which the n memory cells are determined above, except that there is a difference in the number.
It should be noted that, in the embodiment of the present application, regardless of the size of the multimedia data, the data type of the multimedia data, the total storage space size of the electronic device memory, and the remaining storage space size of the electronic device memory, all the multimedia data are divided into n data blocks.
