detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention discloses a data compression method, device and terminal, which can improve the flexibility of data compression. In the embodiment of the present invention, the terminal may include a mobile phone, a tablet computer, a notebook, or other portable device. In the embodiment of the present invention, the target data may be classified into three types: data such as pictures, audio and video, and text files. The essence of data compression is to remove redundant parts of the data without affecting the understanding of the original data. The reason why data can be compressed is because of data redundancy, such as spatial redundancy, time redundancy, etc., in audio and video types. The data in the changed audio or moving object has less variation in the adjacent time series, and only needs to store the difference portion; while the image type data is the same or similar at many pixel points, the text file type Data has a lot of duplicate text. If you store all of them, it will take up more storage space, so data compression only needs to keep uncertain or irrelevant data. Because different data types have the above-mentioned focus time redundancy or spatial redundancy, the embodiment of the present invention can flexibly select a compression mode corresponding to a preset target data type for data compression for different data types of target data. To improve data compression ratio and improve data compression. The details are described below separately.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a data compression method according to an embodiment of the present invention. As shown in FIG. 1, the data compression method may include the following steps.

S101. The terminal determines target data to be compressed.

As an optional implementation manner, the terminal determining the target data to be compressed may include the following steps:

11) The terminal receives operation information input by the user, and the operation information includes operation object data and operation fingerprint data;

12) Whether the terminal detection operation fingerprint data matches the preset operation fingerprint data. If the operation fingerprint data matches the preset operation fingerprint data, the operation target data is used as the target data to be compressed, otherwise, the process ends.

For example, the operation object data is the video program A, and the preset operation fingerprint data is the preset fingerprint data for data compression, such as the middle finger fingerprint of the terminal binding user account; when the user clicks on the video program A with the middle finger When the operation is performed by double-clicking or sliding, the terminal receives the user input operation target data as the video program A, and operates the fingerprint data as the middle finger fingerprint, and after step 12) determines that the middle finger fingerprint is the preset operation fingerprint data, the terminal displays the video program. A is the target data to be compressed.

In this implementation manner, when the fingerprint data is operated as the preset operation fingerprint data in the operation information input by the user, the data compression operation may be triggered, compared with the prior art triggering the data compression operation by the corresponding compression button or the control. Implementations simplify user operations and improve the user experience.

As another optional implementation manner, the terminal determining the target data to be compressed may include the following steps:

21) The terminal determines the ratio of the storage space used by each application installed on the local end to the total storage space of the local end;

22) The terminal uses the storage data corresponding to the application whose value is greater than the second preset threshold as the target data to be compressed.

For example, the applications installed on the local end include cameras, e-books, and video viewing applications. The storage space used by cameras, e-books, and video viewing applications is 8 GB, 2 GB, and 15 GB, respectively. The total storage space of the terminal is 30 GB. The ratio of the storage space used by the local device to the local storage space is 0.27, 0.1, and 0.5, and the second preset threshold is 0.4. The terminal can view the video viewing application that is greater than the second preset threshold. The corresponding stored data is used as the target data to be compressed.

In this embodiment, the storage data corresponding to the application that has a large ratio of the total storage space of the local end is used as the target data to be compressed, and the relatively more available storage space can be released by compressing the data as few times as possible.

S102. The terminal detects a target data type of the target data.

S103. The terminal determines, according to the target data type, a target process of compressing the target data.

In the embodiment of the present invention, the target data type of the target data detected by the terminal may include any one or more types of audio and video, a picture, and a text file. In the embodiment of the present invention, the target process is a process of performing data compression by using a compression mode corresponding to a preset target data type.

Optionally, if the target data type includes multiple data types at the same time, the terminal determines according to the target data type. The target process of the target data may include multiple processes, that is, the terminal may simultaneously invoke the process corresponding to the compressed mode corresponding to each of the plurality of data types to perform data compression in parallel.

S104. The terminal invokes the target process to compress the target data.

In the embodiment of the present invention, the terminal invouses the target process to compress the target data, and compresses the target data into the data block corresponding to the target data type of the target data, for example, compressing the text file type data into the text data block, and sounding Video data is compressed to medium and audio data blocks.

For example, the terminal determines that the target data to be compressed includes the text file and the audio and video data, and the terminal detects, by the step S102, the target data type of the target data of the target data includes the text file data type and the audio and video data type, and the terminal will The target processes A and B for compressing the respective data types are respectively determined for the two data types. Then, in step S104, the terminal may simultaneously call the target process A to compress the text file, and call the target process B to compress the audio and video. Further, the terminal may compress the text file into the data block A and compress the audio and video file into the data block B, wherein the data types stored in the data block A and the data block B are different.

In the data compression method described in FIG. 1, the terminal may determine target data to be compressed, and detect a target data type of the target data, and determine a target process for compressing the target data according to the target data type, by calling the target process, The target data is compressed. It can be seen that the method described in FIG. 1 can flexibly determine the target process according to the target data type of the target data to compress the target data, thereby improving the flexibility of data compression.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart diagram of another data compression method according to an embodiment of the present invention. As shown in FIG. 2, the data compression method may include the following steps.

S201: The terminal determines whether the remaining available storage space of the local end is smaller than the first preset threshold. If the terminal is smaller than the first preset threshold, step S202 is performed. Otherwise, the process ends.

In the embodiment of the present invention, the remaining available storage space is too small, which may affect the running speed of each application of the terminal. Therefore, the terminal may set a first preset threshold according to the total storage space of the device, or the user may customize the first preset threshold. When the terminal can determine that the remaining available storage space of the local end is less than the first preset threshold, the terminal performs data compression on the data to improve the utilization of the storage space, and relatively expand the remaining available storage space.

For example, if the first preset threshold is 5 GB, when the remaining available storage space of the local end is 4 GB, the terminal may determine that the remaining available storage space of the local end is smaller than the first preset threshold, so step S202 may be performed.

S202. The terminal outputs a prompt message for prompting that the remaining available storage space is insufficient.

In the embodiment of the present invention, the terminal may output a prompt message for prompting that the remaining available storage space is insufficient in a voice manner or a pop-up prompt box. Optionally, the prompt message may also specifically indicate how many GB of available storage space is available.

S203. The terminal receives an acknowledge compression command input for the prompt message.

In the embodiment of the present invention, the compression command may be a click or slide operation command input by the user through the touch screen, or a voice command input by the user through the microphone.

S204: The terminal responds to the confirmation compression instruction, and obtains a ratio of a storage space used by each application installed on the local end to a total storage space of the local end;

S205. The terminal uses the storage data corresponding to the application whose value is greater than the second preset threshold as the target data to be compressed.

S206. The terminal detects a target data type of the target data.

S207. The terminal determines, according to the target data type, a target process of compressing the target data.

In the embodiment of the present invention, the target process is a process of performing data compression by using a compression mode corresponding to the target data type set in advance;

S208. The terminal invokes the target process to compress the target data.

For a detailed description of the steps S204 to S208, reference may be made to the related description in the foregoing embodiments of the present invention, and the embodiments of the present invention are not described in detail.

In the data compression method described in FIG. 2, when determining that the remaining available storage space of the local end is smaller than the first preset threshold, the terminal may output a prompt message for prompting that the remaining available storage space is insufficient, and receive the input for the prompt message. The confirmation compression instruction determines the target data to be compressed in response to the confirmation compression instruction, and further detects the target data type of the target data, determines a corresponding target process according to the target data type, and invokes the target process to compress the target data. It can be seen that the method described in FIG. 2 can not only flexibly determine the target process according to the target data type, but also the target process determined according to the target data type can better compress the target data process and improve the data compression effect.

In the embodiment of the present invention, the target data can be classified into three types: data such as pictures, audio and video, and text files. The essence of data compression is to remove redundant parts of the data without affecting the understanding of the original data. The reason why data can be compressed is because of data redundancy, such as spatial redundancy, time redundancy, etc., in audio and video types. The data in the changed audio or moving object has less variation in the adjacent time series, and only needs to store the difference portion; while the image type data is the same or similar at many pixel points, the text file type Data has a lot of duplicate text.
