Detailed Description
In an embodiment of the present invention, a multimedia playing method is provided, where a terminal may determine, for a user, a first sorted set and a second sorted set that meet a playing requirement of the user from a plurality of sorted sets related to at least two pieces of multimedia data. Wherein, the first sorting set is the sorting set with the largest reasonable metric value in the plurality of sorting sets, as shown in fig. 1a, and the second sorting set is the sorting set with the smallest reasonable metric value in the plurality of sorting sets, as shown in fig. 1 b; the reasonable metric value is a metric value that can reflect whether the ranking order of the sorted sets is reasonable or not, and can be determined according to the similarity between adjacent multimedia data in each sorted set. As can be seen from fig. 1a and 1b, a plurality of multimedia data are recorded in each of the first sorted set and the second sorted set, where the multimedia data may include music and/or video. In the process of playing the multimedia data for the user, the terminal can select to play the multimedia data according to the first sorting set or the second sorting set according to the playing information of the currently played multimedia data. The currently played multimedia data refers to multimedia data with the same playing time as the system time of the terminal, for example, if the system time is 10:30, the multimedia data played at 10:30 is currently played multimedia data; the playing information of the currently played multimedia data may include, but is not limited to: the played time length of the currently played multimedia data, the identification information of the currently played multimedia data, and the like.
Based on the above description, in fig. 2, an exemplary flowchart of a multimedia playing method is provided, where the multimedia playing method may be implemented by a terminal, such as a mobile intelligent terminal like a smart phone or a tablet computer, a desktop computer, or an application running in the terminal, such as an application running in the terminal for multimedia playing, or the like. For convenience of description, the embodiment of the present invention takes a terminal as an example for executing the multimedia playing method, where the terminal includes at least two multimedia data.
The terminal may arrange at least two multimedia data in S201 to obtain a plurality of ordering sets, where the ordering order of the multimedia data in any two ordering sets is different. Specifically, after acquiring at least two multimedia data, the terminal may arrange the at least two multimedia data according to different arrangement orders to obtain a plurality of ordering sets; the arrangement herein may include a random arrangement, a full arrangement, and the like. Taking the full arrangement as an example, let total 3 multimedia data, respectively: multimedia data a, multimedia data b, and multimedia data c, then the full permutation is performed on the 3 multimedia data, and a plurality of sorted sets as shown in table 1 can be obtained.
TABLE 1
After obtaining the plurality of sorted sets, a reasonable metric value of each sorted set in the plurality of sorted sets may be obtained in S202, where the reasonable metric value of each sorted set is determined according to a similarity between adjacent multimedia data in each sorted set. The reasonable degree measure value is a measure value which can reflect whether the arrangement sequence of the sorting set is reasonable or not, and whether the arrangement sequence is reasonable or not can be reflected according to visual difference or auditory difference brought to a user by adjacent multimedia data in the sorting set. The smaller the visual difference or the auditory difference brought to the user by the adjacent multimedia data in the playing process is, the more reasonable the arrangement order of the sorting set is. For example, the adjacent multimedia data in the sorting set 1 in table 1 includes multimedia data a and multimedia data b, where the multimedia data a is slow-paced classical music, and the multimedia data b is also slow-paced classical music, that is, the multimedia data a and the multimedia data b have a large similarity, so that the auditory difference brought to the user in the process of sequentially playing the multimedia data a and the multimedia data b is small, and at this time, the sorting order of the sorting set 1 can be considered to be reasonable; as another example, in table 1, the adjacent multimedia data in the sorted set 5 includes multimedia data c and multimedia data a, the multimedia data c is hip-hop music with a fast tempo, and the multimedia data a is classical music with a slow tempo, that is, the similarity between the multimedia data c and the multimedia data a is small, so that the auditory difference brought to the user in the process of playing the multimedia data c and the multimedia data a in sequence is large, and at this time, the sorted set 5 may be considered to be in an unreasonable order.
After the reasonable metric values of each sorting set are obtained, a first sorting set and a second sorting set can be determined from the plurality of sorting sets according to the reasonable metric values of each sorting set, wherein the reasonable metric value of the first sorting set is the largest, and the reasonable metric value of the second sorting set is the smallest. The maximum reasonable measure of the first ordering set may indicate that the first ordering set is most reasonable in the ordering order, i.e. the similarity between adjacent multimedia data in the first ordering set is greater. It can be seen that, when the multimedia data is played in the arrangement order of the first ordering set, the visual difference or the auditory difference brought to the user is the smallest, and thus, the first ordering set can be considered as the most fluent ordering set. The smallest reasonable measure of the second sorted set may indicate that the second sorted set is least reasonable in arrangement order, i.e. the similarity between adjacent multimedia data in the second sorted set is small. As can be seen, when the multimedia data is played in the order of the second sorted set, the visual difference or the auditory difference brought to the user is the largest, and thus, the second sorted set can be regarded as the most jumpy sorted set.
It should be noted that, both the first sorting set and the second sorting set may be ring sorting sets, where a ring sorting set refers to a set in which the first multimedia data and the last multimedia data in the set are defined as adjacent multimedia data, that is, when the multimedia data is played according to the ring sorting set, the first multimedia data in the ring sorting set continues to be played after the last multimedia data in the ring sorting set is played. For example, in the first sorting set shown in fig. 1a, the first multimedia data is multimedia data a, and the last multimedia data is multimedia data G, that is, multimedia data a and multimedia data G are defined as adjacent multimedia data, and then after the playing of multimedia data G is finished, the playing of multimedia data a is continued.
After the first sorted set and the second sorted set are determined, the first sorted set and the second sorted set may be output at a user interface. Playing information of the currently playing multimedia data may also be obtained in S203, and the playing information of the currently playing multimedia data may include but is not limited to: the played time length of the currently played multimedia data, the identification information of the currently played multimedia data, and the like. If the playing information of the currently played multimedia data meets the preset condition, in S204, the multimedia data is played according to the first sorting set and the currently played multimedia data. If the playing information of the currently played multimedia data does not satisfy the preset condition, in S205, the multimedia playing is performed according to the second sorted set and the currently played multimedia data. The method for playing the multimedia data comprises the following steps that: the played time length of the currently played multimedia data is longer than the preset playing time length; or, the ratio of the played time length of the currently played multimedia data to the total played time length of the currently played multimedia data is greater than the preset ratio. The preset playing time and the preset ratio can be determined according to actual service requirements or empirical values, for example, the preset playing time is selected to be 150 seconds, or the preset ratio is selected to be 0.5, and the like.
The embodiment of the invention can arrange a plurality of multimedia data to obtain a plurality of sequencing sets and obtain the reasonable metric value of each sequencing set. Taking the sorting set corresponding to the maximum reasonable metric value as a first sorting set, and taking the sorting set corresponding to the minimum reasonable metric value as a second sorting set; the terminal automatically determines the first sorting set and the second sorting set according to the reasonable degree weighing value without human participation, so that the labor cost can be saved, and the processing efficiency is improved. In the subsequent multimedia playing process, the playing information of the currently played multimedia data can be acquired, and the first sorting set or the second sorting set is dynamically selected according to the playing information of the currently played multimedia data, so that the multimedia playing is carried out; therefore, the played multimedia data can better meet the playing requirement of the user, and the user experience is improved.
In another embodiment, the present invention provides a schematic flow chart of another multimedia playing method in fig. 3. The multimedia playing method of the embodiment of the invention can be implemented by a terminal, such as a mobile intelligent terminal like a smart phone or a tablet computer, a desktop computer, etc., and also can be implemented by an application program running in the terminal, such as an application program for multimedia playing running in the terminal, etc. For convenience of description, the embodiment of the present invention takes a terminal as an example for executing the multimedia playing method, where the terminal includes at least two multimedia data.
The terminal may arrange at least two multimedia data in S301 to obtain a plurality of ordering sets, where the ordering order of the multimedia data in any two ordering sets is different. And in S302, a reasonable metric value of each of the plurality of sorted sets is obtained, where the reasonable metric value of each sorted set is determined according to the similarity between adjacent multimedia data in each sorted set. Setting a plurality of sorting sets to comprise a reference sorting set, wherein the reference sorting set is any one of the plurality of sorting sets; accordingly, the specific implementation of step S302 may be: similarity between adjacent multimedia data in the reference sorted set is calculated, and the first multimedia data and the last multimedia data in the reference sorted set are defined as adjacent multimedia data. Specifically, a feature matrix algorithm may be first used to calculate a feature vector matrix of each multimedia data in the reference sorted set, where the feature matrix algorithm may include, but is not limited to: video transform algorithms such as fourier transform and constant Q transform, audio feature algorithms such as mel cepstrum coefficient, machine learning algorithms such as neural network, and the like. Then, for any adjacent multimedia data in the reference sorted set, the adjacent multimedia data includes multimedia data X and multimedia data Y, a similarity algorithm is used to calculate a similarity between the eigenvector matrix of the multimedia data X and the eigenvector matrix of the multimedia data Y, and the calculated similarity is taken as the similarity between the adjacent multimedia data, where the similarity algorithm may include, but is not limited to: cosine similarity algorithms, euclidean distance algorithms, neural network and other machine learning algorithms, and the like. For convenience of description, the similarity between the adjacent multimedia data mentioned in the embodiments of the present invention may be represented by B, and B satisfies B >0 and B <1, so the similarity between the adjacent multimedia data composed of the multimedia data X and the multimedia data Y may be represented by B (X, Y).
After calculating the similarity between the adjacent multimedia data in the reference sorted set, the sum of the similarities between all the adjacent multimedia data in the reference sorted set can be taken as the reasonable measure of the reference sorted set. For example, taking the reference sorted set as the sorted set C as an example, the sorted set C sequentially records thereon: multimedia data C1, multimedia data C2, multimedia data C3, multimedia data C4 … …, multimedia data cD, and so on, then the reasonable metric value C.E of the sorted set C is B (C1, C2) + B (C2, C3) + B (C3, C4) + … … + B (cD-1, cD) + B (cD, C1).
After the reasonable metric values of each sorting set are obtained, in S303, a first sorting set and a second sorting set may be determined from the plurality of sorting sets according to the reasonable metric values of each sorting set, where the sorting set corresponding to the largest reasonable metric value is the first sorting set, and the sorting set corresponding to the smallest reasonable metric value is the second sorting set. When the multimedia data is subsequently played, the playing information of the currently played multimedia data may be acquired in S304; and in S305, it is determined whether the playing information of the currently playing multimedia data meets a preset condition, where the playing information may include a played time length of the currently playing multimedia data and identification information of the currently playing multimedia data, and the identification information may include a sequence number of the multimedia data in the sorted set. The terminal may perform step S305 when detecting a switching instruction for the currently played multimedia data. The switching instruction may be an instruction generated when the terminal detects that a user performs a switching operation on currently played multimedia data, or an instruction generated when the terminal detects that a difference between a played time length of the currently played multimedia data and a total playing time length of the currently played multimedia data is smaller than a preset difference, where the preset difference may be specified according to a service requirement and may be set to 0 second, 2 seconds, and the like.
If the playing information of the currently played multimedia data meets the preset condition, the time for the user to listen to the currently played multimedia data is longer, and the user likes the currently played multimedia data more, so that the multimedia data similar to the currently played multimedia data can be continuously played for the user in the subsequent multimedia playing process. That is, in the process of the subsequent multimedia playing, the multimedia data with the greater similarity to the currently played multimedia data can be continuously played for the user. Therefore, if the playing information of the currently played multimedia data meets the preset condition, in S306, the multimedia playing is performed according to the first sorting set and the currently played multimedia data. The terminal may determine target multimedia data from the first sorting set according to the currently played multimedia data, and play the target multimedia data after the currently played multimedia data is played, where the target multimedia data is multimedia data that is located behind the currently played multimedia data in the first sorting set and is adjacent to the currently played multimedia data. The terminal may determine the target multimedia data from the first sorted set according to the identification information of the currently played multimedia data. For example, as shown in the first sorting set in fig. 1a, if the currently played multimedia data is multimedia data B and the serial number in the identification information is "2", the multimedia data with the serial number of "3" can be found as the target multimedia data according to the identification information, that is, the target multimedia data is multimedia data C. If the terminal detects that the played time length of the currently played multimedia data is equal to the total played time length of the currently played multimedia data, the currently played multimedia data is considered to be played over; or in the process of playing the currently played multimedia data, if the terminal detects a multimedia switching instruction for the currently played multimedia data, the currently played multimedia data is considered to be played over.
If the playing information of the currently played multimedia data does not meet the preset condition, it indicates that the time for the user to listen to the currently played multimedia data is short, and the user does not like the currently played multimedia data, and then in the subsequent multimedia playing process, the multimedia data different from the currently played multimedia data can be played for the user. That is, in the process of the subsequent multimedia playing, the multimedia data with smaller similarity to the currently played multimedia data can be played for the user. Therefore, if the playing information of the currently played multimedia data does not satisfy the preset condition, in S307, the multimedia playing is performed according to the second sorted set and the currently played multimedia data. In an embodiment, the specific implementation of the multimedia playing according to the second sorted set and the currently played multimedia data may be: and determining target multimedia data from the second sorting set according to the currently played multimedia data, and playing the target multimedia data after the currently played multimedia data is played, wherein the target multimedia data is the multimedia data which is positioned behind the currently played multimedia data and is adjacent to the currently played multimedia data in the second sorting set. For example, as shown in the second sorting set of fig. 1B, if the currently played multimedia data is multimedia data B, the target multimedia data is multimedia data a.
Since the second sorted set is the most jumpy sorted set, the multimedia data played in a short time may be repeatedly played during the multimedia playing process according to the second sorted set and the currently played multimedia data. For example, when playing multimedia data, the terminal defaults to play the multimedia data according to the arrangement order of the first arrangement set, and the currently played multimedia data is the multimedia data B in the first arrangement set shown in fig. 1a, which indicates that the multimedia data a in the first arrangement set is the played multimedia data. However, in the process of playing the multimedia data B, it is detected that the playing information of the multimedia data B does not satisfy the preset condition, at this time, the terminal performs multimedia playing according to the second sorting set shown in fig. 1B and the multimedia data B, that is, the terminal determines the target multimedia data from the second sorting set shown in fig. 1B as the multimedia data B to be the multimedia data a, and if the multimedia data a is taken as the target multimedia data and played, the user may hear the multimedia data a again in a short time, which affects user experience.
Therefore, in order to avoid that the user hears or sees repeated multimedia data in a short time and improve user experience, in the embodiment of the present invention, when multimedia playing is performed according to the second sorted set and currently played multimedia data, the multimedia data in the second sorted set may be further subjected to deduplication processing to filter the multimedia data that has been played for the user in a short time. Correspondingly, in another embodiment, the specific implementation of performing multimedia playing according to the second sorted set and the currently played multimedia data may be: and determining first multimedia data from the second sorting set according to the currently played multimedia data, wherein the first multimedia data is the multimedia data which is positioned behind the currently played multimedia data and is adjacent to the currently played multimedia data in the second sorting set.
And acquiring a deduplication list, wherein the deduplication list comprises at least one multimedia data, and the number of the multimedia data in the deduplication list is smaller than that of the multimedia data in the sorting set. When the duplication removal list is obtained, historical multimedia data played in a preset time and the playing times of the historical multimedia data can be obtained firstly; sequentially selecting a preset number of historical multimedia data according to the playing times and adding the historical multimedia data to a duplicate removal list; the method comprises the steps of sequentially selecting a preset number of historical multimedia data according to the sequence of playing times from high to low, or sequentially selecting a preset number of historical multimedia data according to the sequence of playing frequency from high to low, wherein the playing frequency is obtained by calculation according to the playing times. It should be noted that the preset number may be determined according to an empirical value, for example, 5 is selected, or the preset number may be set according to the number of the multimedia data in the sorting set, for example, 50% of the number of the multimedia data in the sorting set is selected as a value of the preset number; the preset time may be determined based on the current system time of the terminal, for example, the current system time of the terminal is 10:30, and the preset time may be a time period of 10:00-10: 30. In one embodiment, the deduplication list may be updated in real-time, and the deduplication list may be retrieved in the above manner each time the multimedia data is played according to the second sorted set and the currently played multimedia data.
After the deduplication list is obtained, whether the first multimedia data exists in the deduplication list or not can be judged. If the first multimedia data does not exist in the duplication elimination list, the first multimedia data is used as target multimedia data, and the target multimedia data is played after the playing of the currently played multimedia data is finished; and if the first multimedia data exists in the duplication elimination list, determining target multimedia data from the first sorting set according to the first multimedia data, and playing the target multimedia data after the currently played multimedia data is played. If the first multimedia data exists in the deduplication list, the specific implementation of determining the target multimedia data from the first sorting set according to the first multimedia data may be: if the first multimedia data exists in the deduplication list, second multimedia data is determined from the first sorting set according to the first multimedia data, and the second multimedia data is the multimedia data which is located behind the first multimedia data and is adjacent to the first multimedia data in the first sorting set; if the second multimedia data does not exist in the duplication elimination list, the second multimedia data is used as target multimedia data; and if the second multimedia data exists in the deduplication list, determining the next multimedia data from the first sorting set according to the second multimedia data so as to determine the target multimedia data.
When the next multimedia data is determined from the first sorting set according to the second multimedia data to determine the target multimedia data, the next multimedia data can be determined from the first sorting set according to the second multimedia data, wherein the next multimedia data is the multimedia data which is positioned behind the second multimedia data in the first sorting set and is adjacent to the second multimedia data, if the next multimedia data still exists in the deduplication list, the new next multimedia data is determined from the first sorting set according to the next multimedia data, and so on until the determined next multimedia data is not in the deduplication list, and at this time, the determined next multimedia data is used as the target multimedia data. In other embodiments, the next multimedia data from the first sorted set may also be determined according to the second multimedia data, and the next multimedia data is directly determined as the target multimedia data.
For example, a first sorted set is shown in FIG. 1a, a second sorted set is shown in FIG. 1b, and a deduplication list is shown in FIG. 4. The currently played multimedia data is multimedia data B, and the terminal determines the first multimedia data as multimedia data a from the second sorted set shown in fig. 1B according to the multimedia data B. When detecting that the multimedia data a exists in the deduplication list shown in fig. 4, the terminal queries the second multimedia data as multimedia data B from the first ordering set shown in fig. 1a according to the multimedia data a. But multimedia data B still exists in the deduplication list shown in fig. 4, so the terminal continues to determine the next multimedia data from the first sorted set as multimedia data C according to multimedia data B. Since multimedia data C still exists in the deduplication list shown in fig. 4, the terminal continues to determine a new next multimedia data from the first sorted set as multimedia data D according to multimedia data C. And the multimedia data D does not exist in the deduplication list shown in fig. 4, the multimedia data D can be regarded as target multimedia data.
The embodiment of the invention can arrange a plurality of multimedia data to obtain a plurality of sequencing sets and obtain the reasonable metric value of each sequencing set. Taking the sorting set corresponding to the maximum reasonable metric value as a first sorting set, and taking the sorting set corresponding to the minimum reasonable metric value as a second sorting set; the terminal automatically determines the first sorting set and the second sorting set according to the reasonable degree weighing value without human participation, so that the labor cost can be saved, and the processing efficiency is improved. In the subsequent multimedia playing process, the playing information of the currently played multimedia data can be acquired, and the first sorting set or the second sorting set is dynamically selected according to the playing information of the currently played multimedia data, so that the multimedia playing is carried out; therefore, the played multimedia data can better meet the playing requirement of the user, and the user experience is improved.
Based on the description of the above method embodiment, the embodiment of the present invention proposes the application scenarios shown in fig. 5a to 5d, where the first sorting set mentioned in the application scenario may be shown in fig. 1a, the second sorting set may be shown in fig. 1b, and the deduplication list may be shown in fig. 4. When the user wants to play the multimedia data, the multimedia playing function in the terminal can be turned on, as shown in fig. 5 a. At this time, the terminal may present a sorting set for the user, where the presented sorting set may be the first sorting set or the second sorting set. For convenience of description, in the embodiment of the present invention, the presented sorting set is taken as a first sorting set as an example, a user may arbitrarily select one multimedia data from the first sorting set, and the terminal plays the multimedia data selected by the user as the first multimedia data according to a selection instruction of the user, for example, selects multimedia data a as the first multimedia data, as shown in fig. 5 a.
In the subsequent multimedia playing process, the terminal can judge whether the playing information of the currently played multimedia data meets the preset condition; if yes, multimedia playing is carried out according to the first sequencing set and the currently played multimedia data; and if not, performing multimedia playing according to the second sorting set and the currently played multimedia data. For example, if the currently played multimedia data is multimedia data B, and it is detected that the playing information of the multimedia data B satisfies the preset condition, the target multimedia data is determined to be multimedia data C in the first sorting set, and the multimedia data C is played after the playing of the multimedia data B is finished, as shown in fig. 5B. If it is detected that the playing information of the multimedia data B does not satisfy the preset condition, determining the target multimedia data in the second sorting set as the multimedia data a, and playing the multimedia data a after the playing of the multimedia data B is finished, as shown in fig. 5 c.
Optionally, if it is detected that the playing information of the multimedia data B does not satisfy the preset condition, the first multimedia data is determined to be the multimedia data a in the second sorting set. But multimedia data a exists in the deduplication list, the second multimedia data is determined to be multimedia data B in the first ordering set. But multimedia data B still exists in the deduplication list, so the terminal continues to determine the next multimedia data from the first ordering set as multimedia data C. However, multimedia data C also exists in the deduplication list, so the terminal continues to determine that the new next multimedia data from the first sorted set is multimedia data D. And the multimedia data D does not exist in the deduplication list, so the multimedia data D is taken as the target multimedia data, and after the multimedia data B is played, the multimedia data D is played, as shown in fig. 5D.
Based on the description of the above method embodiment, in an embodiment, an embodiment of the present invention further provides a schematic structural diagram of a multimedia playing apparatus as shown in fig. 6; the multimedia playing device runs in a terminal, and the terminal comprises at least two multimedia data. As shown in fig. 6, the multimedia playing apparatus in the embodiment of the present invention may include:
