The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a program importing method according to an embodiment of the present disclosure. In this embodiment, the program importing method is used to import a television program into a video playing device. The execution main body is a video playing device.
The program importing method shown in fig. 1 includes the following steps:
s11: when the video playing device is in the target mode, the video playing device verifies the content of the target file according to a preset verification strategy.
In some embodiments, the video playing device is a device capable of playing video, such as a television, a computer, and the like. The target mode is a target operation mode of the operation process of the video playing device. For example, a user operates the video playback device, sets a preset mode (preset mode) as a target mode of the video playback device, automatically verifies the content of a target file when the video playback device is in the mode, or sets a factory mode as a target mode of the video playback device, i.e., both the preset mode and the factory mode are target modes.
It can be understood that the target mode may be preset by a user, and when the video playback device is in the target mode, the video playback device may automatically verify the content of the target file according to a preset verification policy.
The preset verification policy is used for describing a logical process of verifying whether the content of the target file is the target content. For example, the recorded content includes A, B, C three data classification fields, and the content includes a piece of tv program information, and the tv program information includes data corresponding to the 3 data classification fields, the data classification field of the content is verified first by using a preset verification policy, and then the data corresponding to the data classification field included in each piece of tv program information is verified.
The content of the target file is the content recorded in the encrypted target file in the target storage area. For example, a target file with a file name dvbscl and a file format txt, which is encrypted by an encryption device using a preset encryption policy, it is understood that the target storage area may be a storage area in a mobile storage device connected to the video playback device, or a storage area in a cloud server connected to the video playback device. The target file may be encrypted by using a preset encryption policy when being imported into the target storage area, or encrypted by using a preset encryption policy before being imported into the target storage area and then imported into the target storage area.
Before the television program is introduced into the video playback device, the video playback device needs to be connected to the device configured with the target storage area, for example, a mobile storage device storing the target file is connected to the video playback device, or the video playback device is connected to the cloud server through a communication network, so that the storage area storing the target file in the cloud server can be accessed.
In this embodiment, when the video playback device is in the target mode, the video playback device verifies the content of the target file according to the preset verification policy, and since the content recorded in the target file is not necessarily the television program information to be imported, for example, the file with the file name of the target file name, and the file is not the television program information recorded in the file, the content of the target file needs to be verified by using the preset verification policy to ensure the correctness of the content of the target file, so that the program can be smoothly imported into the video playback device.
As for when the video playing device verifies the content of the target file according to the preset verification policy, the following two scenarios can be included, but not limited to.
Scene 1: and when the video playing equipment is in the target mode, the video playing equipment verifies the content of the target file according to a preset verification strategy.
For example, when a television is manufactured, a tester tests the television, connects the usb disk storing the target file with the television, and when the television is in a factory mode, the television automatically verifies the content of the target file in the usb disk according to a preset verification policy.
Scene 2: and when the updated television program information exists and the video playing equipment is in the target mode, the video playing equipment verifies the content of the target file according to a preset verification strategy.
For example, when updated television program information exists, a user connects a usb disk storing a target file with a television, the updated television program information is recorded in the target file, and the television automatically verifies the content of the target file in the usb disk according to a preset verification policy if the user selects a television preset mode.
S12: and if the verification is successful, the video playing equipment decrypts the encrypted target file according to the decryption strategy to obtain the target file.
In some embodiments, the decryption policy is used to describe a logical process of decrypting the target file, and the decryption policy corresponds to an encryption policy of encrypting the target file.
Several pieces of TV program information are recorded in the target file. Each piece of television program information comprises data corresponding to a plurality of data classification fields.
As shown in fig. 3, the target file that is successfully verified includes 16 pieces of television program information, which are channels (channels) 1 to 16, respectively.
In some embodiments, the decryption policy may be a preconfigured decryption program and the encryption policy may be a preconfigured encryption policy.
It is understood that, since the target file is successfully verified, the video playback device may decrypt the encrypted target file by using the decryption policy when the encrypted target file is exported from the target storage area, or decrypt the encrypted target file by using the decryption policy after the encrypted target file is exported from the target storage area.
S13: and importing the plurality of pieces of television program information in the target file into the video playing equipment.
In some embodiments, it can be understood that the content in the obtained target file is extracted to obtain several pieces of television program information, and then the obtained several pieces of television program information are imported into the storage of the video playing device. When the channel searching is carried out through the video playing equipment, the imported television program information can be called based on codes recorded in an operating system of the video playing equipment, so that the channel searching efficiency is improved.
In an embodiment of the present application, when the video playback device is in the target mode, before the video playback device verifies the content of the target file according to a preset verification policy, the method further includes:
the video playing device identifies a plurality of encrypted files in the target storage area according to a preset identification strategy to obtain encrypted target files.
In this embodiment, the preset identification policy is a logical process describing identification of several encrypted files in the target storage area. For example, the character string dvbscl.txt is the target file name, so the file names of all files in the target storage area are identified one by one, and an encrypted file with the file name dvbscl.txt is obtained, namely the encrypted file is the encrypted target file.
It can be understood that, in general, a plurality of files are stored in the target storage area, and the encrypted target file is only one of the plurality of files, and if all files are directly verified according to the preset verification policy, the import efficiency is low, so in order to accurately and quickly import the television program information in the target file into the video playing device, when the video playing device is in the target mode, a plurality of encrypted files in the target storage area need to be identified according to the preset identification policy, and whether the encrypted target file is determined according to the identification result.
In some embodiments, since only the target file is encrypted by using the preset encryption policy when the target file is stored in the target storage area, the files stored in the target storage area may include encrypted files and unencrypted files.
Therefore, a plurality of files in the target storage area are identified according to the preset identification strategy, and the encrypted target file is obtained.
In some embodiments, since the target file is a file encrypted by using a preset encryption policy, a number of files in the target storage area are identified according to the preset encryption policy to obtain the encrypted target file.
In this embodiment, the preset encryption policy is a logical process describing encryption of the target file. For example, the target file is encrypted using a preset encryption algorithm.
As a possible implementation manner of this embodiment, the identifying, by the video playing device, a plurality of encrypted files in the target storage area according to a preset identification policy to obtain an encrypted target file includes:
the video playing equipment identifies the file names of a plurality of encrypted files in the target storage area one by one;
and if the file name contains the target character string, confirming that the file containing the target character string is an encrypted target file.
In this embodiment, the target character string is a string of characters consisting of numbers and letters, and it is understood that the target character string may be set in advance, for example, the target character string is dvbscl.
Illustratively, the target storage area includes 3 encrypted files, such as file 1, file 2, and file 3, and the file names are dvbscl.txt, aabscl.txt, and ccbscl.txt, respectively, and the video playback device identifies the file names of the 3 encrypted files one by one, where the file name of file 1 includes a target character string "dvbscl.txt", and confirms the target file with 1-bit encryption of the file.
When the target character string is recognized, each character is recognized in order, and whether or not a plurality of characters connected in order are the target character string is confirmed.
In an embodiment of the present application, when the video playback device is in the target mode, the verifying, by the video playback device, the content of the target file according to a preset verification policy includes:
when the video playing equipment is in a target mode, the video playing equipment verifies the data format of the content of the target file according to the preset verification strategy; the data format includes a plurality of data field classifications;
if the data format of the content of the target file is a preset data format, confirming that the content of the target file is a plurality of pieces of television program information;
and verifying whether each data field in each piece of television program information in the content of the target file is valid or not.
It should be noted that the data format of the content of the target file is a set of data field classifications corresponding to each data field in the data of the content record. The preset data format is a set of data field classifications corresponding to a plurality of data which influence video display. For example, referring to fig. 3, the data field classifications corresponding to the data affecting the display of the television program include 8 data field classifications, such as channel no, servicename, satelite no, servicetype, scrambleled, frequency, polarity, and sr, and the 8 data field classifications are included in the preset data format.
In this embodiment, when the video playback device is in the target mode, the video playback device verifies, according to the preset verification policy, whether the multiple data field classifications corresponding to the multiple data in the content of the target file are in one-to-one correspondence with the data field classifications corresponding to the multiple data that determine to affect video display, if so, the data format of the content of the target file is the preset data format, and the content of the corresponding target file is the multiple pieces of television program information, that is, the data format of each piece of recorded television program information is the preset data format. Further, on the basis that the data format of the content of the target file is a preset data format, verifying whether each data field in each piece of television program information is valid, for example, whether a channel no is a pure number, and the number is smaller than the number of preset channels, if the channel no is a pure number and smaller than the number of preset channels, it indicates that the channel no is valid, and otherwise it is invalid, or if a service type is one of 3 types, such as tv, radio, data, and the like, and if the service type is one of the 3 types, it indicates that the service type is valid, and otherwise it is invalid.
It should be noted that, when it is verified that one or more data fields in each piece of television program information in the content of the target file are invalid, the piece of television program information is identified as invalid and is not imported into the video playing device, otherwise, when each data field in each piece of television program information is valid, the piece of television program information is identified as valid and is imported into the video playing device.
As a possible implementation manner of this embodiment, the verifying whether each data field in each piece of television program information in the content of the target file is valid includes:
if all data fields in the television program information meet preset conditions, determining that the television program information is valid television program information;
and if at least one data field in the television program information does not meet the preset condition, determining that the television program information is invalid television program information.
In the present embodiment, the preset condition is to describe a logical process of determining whether a data field in a television program satisfies a requirement. It is understood that, since the predetermined data format includes a plurality of data classification fields, each data classification field corresponds to one data field, and one data field corresponds to one determination condition, the predetermined condition includes the determination condition for each data field of the plurality of data fields.
Illustratively, one piece of television program information includes data fields corresponding to 3 data field classifications, such as a channel no, a service type, and a scrambled, which are respectively 1, TV, and tube, and the preset condition also includes a determination condition for the data fields corresponding to the 3 data field classifications, which is whether the channel no is a pure number, and the number is less than 10 of preset channels, whether the service type is one of 3 types, such as TV, radio, and data, and whether the scrambled is one of tube or false, where the tube is encrypted. Through judgment, the television program information meets the preset condition, so that the television program information is determined to be effective television program information.
In an embodiment of the present application, verifying, by the video playback device, the content of the target file according to a preset verification policy when the video playback device is in the target mode includes:
and if the data format of the content of the target file is not the preset data format, stopping verifying the content of the target file.
It can be understood that if the content of the target file is the television program information, the data format of the target file is also the corresponding preset data format, and there is a need to continuously verify the content of the target file, and if the data format of the target file is not the corresponding preset data format, it indicates that the target file does not record the television program information, or that the data field of the recorded television program information is not a required data field.
Referring to fig. 2, in an embodiment of the present application, before the video playback device verifies the content of the target file according to a preset verification policy when the video playback device is in the target mode, the method further includes:
s21: acquiring a plurality of pieces of television program information; each piece of television program information comprises a plurality of data fields;
s22: determining a strategy by using a preset target data field, acquiring the target data field in each piece of television program information, and constructing to obtain new television program information;
s23: forming the target file according to the plurality of pieces of new television program information obtained by construction;
s24: and encrypting the target file by using a preset encryption strategy and storing the target file in the target storage area.
In this embodiment, the preset target data field determination policy is a logic process for describing a data field corresponding to a data field classification for obtaining a plurality of data that determine to affect video display in each piece of tv program information. It can be understood that, the target data field in each piece of television program information is obtained based on the data field classification corresponding to the data which are determined to affect the video display, so as to construct and obtain new television program information.
For example, the acquired piece of television program information includes an a data field, a B data field, a C data field, a D data field, and an E data field. The data fields A, the data fields B and the data fields C are data fields corresponding to a plurality of data of the fixation response video display in a classified mode, so that 3 data fields such as the data fields A, the data fields B and the data fields C of the television program information are obtained by utilizing a preset target data field determining strategy, and a new piece of television program information is obtained based on the 3 data fields. By analogy, a plurality of pieces of new television program information are constructed and obtained to form a target file.
