Detailed Description
In order to make the purpose, technical solution and technical effect of the present application clearer and clearer, the following further describes the present application in detail, and it should be understood that the specific embodiments described herein are only used for explaining the present application, and are not used for limiting the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a storing method of an fm broadcast station according to an embodiment of the present application, where the specific flow of the storing method of the fm broadcast station may be as follows:
s101: a plurality of FM broadcast stations to be stored are obtained.
Specifically, the mobile terminal may serve as an fm broadcast receiving terminal, and when switching from a currently listened to fm broadcast station to a next fm broadcast station, it is generally necessary for a user to know information such as a frequency, a name, or an index of the next fm broadcast station in advance, otherwise the user may not be able to accurately switch the fm broadcast station. Furthermore, in order to quickly and accurately obtain information such as the station frequency, name, or index of the next fm broadcast station when switching fm broadcast stations, a user generally stores some commonly listened to or preferred fm broadcast stations in the mobile terminal. In a specific implementation, the plurality of fm broadcast stations to be stored may be selected by the user based on the listening habits and/or personal preferences of the user, or may be determined by the mobile terminal according to the fm broadcast station listened to by the user in the latest period of time and the listening duration of the listened fm broadcast station, where the fm broadcast stations to be stored may include the station frequency, name, index, and the like of the fm broadcast station.
S102: and determining a station index value corresponding to each FM broadcast station.
Each fm broadcast station has a unique station index value, and the station index value may be generated randomly or according to a certain method, for example, according to the station frequency of the fm broadcast station.
In some embodiments, the S102 may specifically include:
s1021: and converting the radio station frequency of each FM broadcast station into a corresponding radio station index value according to a preset rule.
In view of the fact that the unit of the station frequency of the fm broadcast station is generally MHz, and the station frequency may not be an integer but may have a digit after a decimal point, the preset rule may be to obtain the corresponding station index value by extending the value of the station frequency by ten times. For example, the station index value corresponding to the fm broadcast station with a station frequency of 104.7MHz may be 1047, the station index value corresponding to the fm broadcast station with a station frequency of 87.6MHz may be 876, and the station index value corresponding to the fm broadcast station with a station frequency of 108.5MHz may be 1085.
In some alternative embodiments, the above S102 may also include:
s1022: and inquiring a pre-established data table to obtain a radio station index value corresponding to each FM broadcast station, wherein the data table records the one-to-one correspondence between the radio station frequency and the radio station index value.
In the specific implementation, the mobile terminal may obtain the corresponding radio station index value by querying the data table according to the radio station frequency of the fm broadcast station.
S103: and sequencing the radio station index values to obtain the sequence number of each radio station index value.
In this embodiment, the radio station index values are data strings, and the mobile terminal may sort the radio station index values according to the numerical values to obtain the sequence number of each radio station index value, where the greater the sequence number is, the greater the radio station index value may be, that is, the greater the radio station index value of the sequence number is, the smaller the radio station index value of the sequence number is.
In some embodiments, in view that lengths of station index values corresponding to different fm broadcast stations may be different, in order to facilitate a comparison operation on the station index values in a subsequent step, as shown in fig. 2, the step S103 may specifically include:
s1031: and judging whether the lengths of the station index values are uniform, if not, sequentially executing S1032 and S1033, and if so, skipping S1032 and S1033 and directly executing S1034.
S1032: a station index value for the longest character and a first length of the station index value for the longest character are determined from the station index values.
Specifically, when the station index values are not uniform in length, for example, there are three station index values 177991, 1222266981, and 1222267866, the station index value for which the longest character can be obtained has two station index values 1222266981 and 1222267866, and the length (i.e., the first length) of the station index value for the longest character is 10.
S1033: and increasing the length of the station index value with the length smaller than the first length to the first length so as to unify the lengths of the station index values.
Wherein, for a station index value with a length smaller than the first length, the length of the station index value can be increased to the first length by adding one or more virtual values at the forefront of the station index value. The virtual value may be smaller than any value, for example, the virtual value &, & may be in a magnitude relationship with other values: and <0<1<2<3<4<5<6<7<8<9<10<11< … …. As an example, the length of the station index value 177991 is increased to the first length of 10, and the processed station index value & & &177991 may be obtained.
S1034: and sequencing the radio station index values with uniform length according to the numerical values to obtain the sequence number of each radio station index value.
Wherein, the larger the sequence number is, the larger the corresponding radio station index value is. As an example, the three station index values with uniform length are 1222266981, 1222267866 and & &177991 respectively, and after the three station index values are sorted in descending order of numerical value, the following can be obtained: and & &177991, 1222266981 and 1222267866, the corresponding sequence numbers may be n, (n +1) and (n +2) in sequence, and in a specific implementation, n may take a value of 1, that is, after the three station index values are sorted in order of magnitude from small to large, the mobile terminal may mark a sequence number to each station index value from 1 in sequence from small to large.
S104: and determining the difference value between any two adjacent station index values in the sequence numbers.
With continued reference to fig. 2, the step S104 may specifically include:
s1041: and comparing the highest numerical value with the two adjacent station index values in the sequence number to determine whether the two adjacent station index values are the same, if so, executing S1042, and otherwise, executing S1043.
In the above example, any two adjacent station index values in the sequence number may refer to: two station index values & & & &177991 and 1222266981 with sequence numbers 1 and 2, respectively, and two station index values 1222266981 and 1222267866 with sequence numbers 2 and 3, respectively. Specifically, for two station index values & & & &177991 and 1222266981 with sequence numbers of 1 and 2, respectively, the numerical values of the most significant bits thereof are & and 1, respectively, and it can be known by comparison that the numerical values of the most significant bits in & & &177991 and 1222266981 are not the same. For the two station index values 1222266981 and 1222267866 with sequence numbers 2 and 3, the highest bit values are 1 and 1, respectively, and it can be seen by comparison that the two values are the same, i.e., the highest bit values in 1222266981 and 1222267866 are the same.
S1042: the most significant bit is updated with the next bit of the most significant bit, and the above S1041 is returned to be executed.
As for the previous example, for the two station index values 1222266981 and 1222267866 with sequence numbers 2 and 3, respectively, the highest values are 1 and 1, respectively, and are the same, the mobile terminal may update the highest bit with the next highest bit (i.e., the second highest bit) and return to perform S1041 to further compare whether the values of the second highest bits (i.e., 2 and 2) in 1222266981 and 1222267866 are the same, so that S1042 and S1041 can form a loop, compare whether the values of the same bits in 1222266981 and 1222267866 are the same one by one from high to low, and end the loop when the values of the same bits are not the same, that is, for 1222266981 and 1222267866, after comparing the values of the seventh highest bits 6 and 7, end the loop and then perform S1043.
S1043: and taking the numerical value from the highest bit to the lowest bit in the radio station index value with the larger sequence number as the difference value corresponding to the radio station index value with the larger sequence number.
Specifically, for any two adjacent station index values in the sequence numbers, when the highest numerical value obtained by comparison is not the same, the numerical value from the highest position to the lowest position in the station index values with the larger sequence number in the two station index values can be used as the difference value corresponding to the station index value with the larger sequence number. As for the previous example, for the two station index values & & & &177991 and 1222266981 with sequence numbers 1 and 2 respectively, the highest bit (i.e., the first highest bit) values are & and 1 respectively, and are not the same, the highest to lowest bit values of the station index values 1222266981 with sequence number 2 are 1222266981, and the difference value corresponding to the station index value 1222266981 is 1222266981. For the two station indexes 1222266981 and 1222267866 with sequence numbers 2 and 3, the highest (i.e., the seventh highest) value is 6 and 7, respectively, and they are not the same, so the value from the highest (i.e., the seventh highest) to the lowest in the station index 1222267866 with sequence number 7 is 7866, and the difference between the station index 1222267866 and the station index is 7866.
S105: and storing a plurality of FM broadcasting stations to be stored according to the sequence number, the station index value and the difference value.
With continued reference to fig. 2, the step S105 may specifically include:
s1051: the smallest sequence number is determined from the sequence numbers to obtain the target sequence number.
Taking three station index values & & & & &177991, 1222266981 and 1222267866 with sequence numbers of 1, 2 and 3 as examples, the minimum sequence number is 1, that is, the target sequence number is 1.
S1052: and taking the radio station index value corresponding to the target sequence number as an initial radio station index value.
As in the previous example, the starting station index value is the station index value & & & &177991 with a sequence number of 1.
S1053: and the sequence number, the target sequence number, the initial radio station index value and the difference value are stored in an associated manner, so that a plurality of FM broadcast stations to be stored are stored.
Specifically, the starting station index value with the sequence number as the target sequence number is stored, and the station index value with the sequence number behind the target sequence number is stored with the difference value of the station index value relative to the station index value located one bit before the station index value on the sequence number, so that the complete station index value is not required to be stored, and the difference value is generally smaller than the corresponding station index value, so that the storage method of the frequency modulation broadcasting station in the application is favorable for reducing the problem of storage space waste caused by independent storage of the frequency modulation broadcasting station in the prior art. It should be noted that, when the virtual value exists in the starting station index value and the difference value, the stored starting station index value and the stored difference value may be the starting station index value and the difference value after the virtual value is removed, so as to save the storage space.
For example, for three station index values & & & &177991, 1222266981 and 1222267866 with sequence numbers of 1, 2 and 3, respectively, a difference value of the station index value 1222266981 with respect to the station index value & & &177991 located at the previous bit thereof in the sequence number may be 1222266981, a difference value of the station index value 1222267866 with respect to the station index value 1222266981 located at the previous bit thereof in the sequence number may be 7866, and the station index values to be stored corresponding to the three station index values & & & & &177991, 1222266981 and 1222267866 with sequence numbers of 1, 2 and 3, respectively, may be 177991, 1222266981 and 7866 in this order.
Further, after the above S105, the method further includes:
s106: and acquiring a stored reading instruction of the FM broadcasting station.
Specifically, when a user needs to switch a currently listened FM broadcast station on the mobile terminal to a next FM broadcast station, the user may trigger the mobile terminal to generate a stored FM broadcast station reading instruction, so that the mobile terminal can provide the stored FM broadcast stations to the user after receiving the stored FM broadcast station reading instruction, and the user can select one of the stored FM broadcast stations to switch the currently listened FM broadcast station.
S107: and determining the stored FM broadcasting station based on the sequence number, the target sequence number, the initial broadcasting station index value and the difference value which are stored in a related manner according to the stored FM broadcasting station reading instruction.
After obtaining the stored fm broadcast station reading instruction, the mobile terminal may convert the sequence number, the target sequence number, the starting station index value, and the difference value, which are stored in association, into an fm broadcast station based on the reverse operation of S102 to S105, and display the converted fm broadcast station to the user. Specifically, the index value of the starting radio station may be converted into the fm broadcast station with the minimum sequence number based on the preset rule or by querying the data table, and then the fm broadcast station with the second minimum sequence number may be determined based on the difference value corresponding to the second minimum sequence number and the fm broadcast station with the minimum sequence number, and so on, and the fm broadcast station with the sequence number may be determined based on the difference value corresponding to the sequence number after the target sequence number (i.e., the minimum sequence number) and the fm broadcast station with the previous sequence number in sequence according to the sequence number from small to large.
Further, after obtaining the FM broadcast stations of each sequence number, as shown in fig. 3, the mobile terminal may display the obtained FM broadcast stations (e.g., FM 104.7MHz, FM 87.6MHz, FM 108.5MHz, etc.) on the station switching interface a, so that the user can select a target FM broadcast station from the displayed FM broadcast stations as needed to switch the currently listened FM broadcast station (e.g., 106.1 MHz).
Different from the prior art, the storage method of the fm broadcast station in this embodiment includes obtaining a plurality of fm broadcast stations to be stored, determining a station index value corresponding to each fm broadcast station, then sorting the station index values to obtain a sequence number of each station index value, determining a difference value between any two adjacent station index values in the sequence number, and then storing the plurality of fm broadcast stations to be stored according to the sequence number, the station index values and the difference value.
