The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC 280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC 280 is also configured to interface with BSCs 275, which may be coupled to base stations via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS 270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS 270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz, 5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. As a typical operation of the wireless communication system, the BS 270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station is processed within a particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN 290 interfaces with the MSC 280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS 270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

In the prior art, media applications such as a media player depend on a multimedia database of a system, when a media file in a media folder is modified by a third-party application, records in the media database, a media play list and files in each media folder of the system cannot be synchronized in real time, after the media database is updated, information such as the played time length, remarks and TAG TAGs of the media file is deleted, and when a user plays the media again next time, the played time cannot be recorded, so that the user experience is poor.

Therefore, the invention provides a solution, which depends on a database of a media application, when a media file in a media folder changes (such as a third-party application renames, deletes and modifies the media file, and removes an SD card, etc.), a deletion operation is not executed for a file which does not exist in the media database, but the record in the database is updated to an unactivated state, a playlist is updated, the nonexistent media file is hidden, and the playing time length, remark and TAG TAG information are updated to the media database in real time, so that the integrity of media information is ensured, the effectiveness of an image in the media playlist is ensured, and the user experience is improved.

Specifically, as shown in fig. 3, a first embodiment of the present invention provides a media playing device, including: a file scanning module 201, a comparison analysis module 202 and an update module 203, wherein:

a file scanning module 201, configured to scan a media file in the media folder and a media database of a media application when a media file scanning condition is triggered is detected, to obtain first media file information in the media folder and second media file information in the media database;

Further, the matching update module 202 is further configured to insert a storage path of the newly added media file and a record related to a file duration into the media database if the media file is newly added to the media folder;

and/or the presence of a gas in the gas,

Further, the matching update module 202 is further configured to update a corresponding record of the media database and set the record as an activated state if the newly added media file in the media folder is a media file that reappears due to the SD card being moved in;

and/or if the deleted media file in the media folder is lost due to the removal of the SD card, updating a corresponding record in the media database, and setting the record in an inactivated state;

and/or if the modified media file in the media folder is the renamed media file and the storage path of the media file is changed, updating the corresponding record in the media database, and changing the storage path of the matched record into the storage path of the current media file; or, if the modified media file in the media folder is the media file with the preserved file name and the original file replaced, inserting the related information of the media file into the media database as a new record.

Specifically, the media playing device of the present embodiment may be applied to a mobile terminal such as a mobile phone, a tablet computer, a PDA or a notebook computer, and may also be applied to a fixed terminal such as a digital TV or a desktop computer, which is not limited in this embodiment. This embodiment is exemplified by a mobile phone.

In this embodiment, media playing application software, such as a media player, is installed on a terminal, such as a mobile phone, and a played media file may be an audio file, a video file, or an audio-video file.

The media player typically relies on a multimedia database (hereinafter media database) in the terminal system.

The multimedia database is mainly recorded with storage paths, file names, file sizes, file durations, file types and the like of all media files in the media folder, and additionally maintains parameter information such as media playing durations, remarks, TAGs (TAGs) and the like for the media files.

When a user starts the media application software to play the audio and video files, the media application software firstly calls the media file information recorded in the media database, and then calls the corresponding media files in the media folder through the media file information recorded in the media database, so that corresponding images are displayed, and media playing is realized.

Because the existing media application software depends on the media database of the system, when the media files in the media folders are modified by a third-party application other than the media application (for example, the third-party application performs operations such as renaming and modifying on the media files, or a Secure Digital Memory Card (SD Card) is moved out/in), the records and the media playlists in the media database cannot be synchronized with the files in each media folder of the system in real time. At this time, during playing, there are some records in the media database, and the corresponding media file cannot be found through the storage path, resulting in poor user experience. In addition, since the media player additionally maintains information such as the time length of the played media, the remark, the TAG, etc. for the media file, the user does not want the information to be deleted.

In order to avoid the foregoing situation, in this embodiment, a corresponding trigger condition is set to scan the media file, and the media file information in the media folder of the terminal system and the media file information in the media database are obtained through scanning, so that the records and the media playlist in the media database are synchronized with the files in each media folder of the system in real time, the consistency and integrity of the media file information are ensured, and the user experience is improved. When scanning, the record of the media file does not exist in the media database, the database is updated without executing deletion operation, the record is set to be in an inactivated state, the play list is updated, and the nonexistent media file is hidden.

In this embodiment, the media file information may include: the file name, storage path, file duration, file size, last modification time of the file and/or whether the file is activated, the time duration for which the file has been played, notes, TAG, etc. of the media file.

Specifically, the present embodiment sets the following media file scanning triggering mechanism:

1. when entering the media application or returning to the main interface of the media play list after starting the media application, the media files need to be scanned, and the media play list and the media database of the media application need to be updated;

2. when the SD card is inserted/removed, the media file needs to be scanned, and a media playing list and a media database of the media application are updated;

3. and monitoring the broadcast of the folder content change, and starting file scanning when receiving the broadcast so as to provide extension for the function of actively requesting scanning.

When the triggering of a media file scanning condition is detected, scanning a media file in a media folder of a terminal system and a media database of a media application, and acquiring media file information in the media folder of the terminal system and media file information in the media database.

As a media file scanning method, the following media file filtering mechanism may be adopted:

as shown in fig. 4, taking a video file as an example, the specific flow is as follows:

s11, scanning the file;

s12, if the file is judged to be a file, the operation goes to S13; otherwise, returning to S11;

s13, judging whether the file is a video format file; if not, go to S14;

s14, analyzing the file header information;

s15, judging whether the mimetype comprises a 'video' field and the like; if so, judging the file to be a video file, otherwise, judging the file not to be the video file.

Specifically, after initiating a file scan, the media folders on the internal/external memory of the terminal are scanned in a step-by-step traversal, filtering the media file format, e.g., whether the file suffix is.mp 4/. wmv, etc. If the format is not the format, the file header information is analyzed, and whether the mimetype of the file header information comprises a 'video/' field and the like is judged. After the media file is scanned, the file is analyzed, decoded and previewed, so that the scanning efficiency of the media file can be improved.

For the scanning of the media database of the media application, key information of the media files recorded in the multimedia database is mainly scanned, such as: storage path, file name, file size, file duration, TAG, remark, played duration information, file type, file activation state and other information.

After the media file information in the media folder and the media file information in the media database are obtained, the media file information in the media folder and the media file information in the media database are compared to judge whether the media file information in the media folder changes or not, if yes, the media file information recorded in the media database is correspondingly updated, and meanwhile, a media playlist is updated.

The method comprises the steps of judging whether media file information in a media folder is changed or not, and mainly judging whether media files are newly added, deleted, modified and the like in the media folder or not.

When the media files in the media folder are changed (such as the third-party application file manager renames, deletes, modifies the content of the media files, and removes the SD card), the multimedia data updating mechanism of the media application is triggered.

The present embodiment takes into account: when the third-party application performs operations such as renaming and modifying on the media file or performs operations of moving out/in the SD card, but the media database of the gallery is not updated in time, the problem exists: and if some records in the database cannot find the corresponding media file through the storage path of the records, judging that the file does not exist. In addition, since the gallery additionally maintains parameter information such as category TAG, favorites, privacy, etc. for the media files, the user does not want to delete such information.

Thus, when scanning is performed, for a record that does not exist, a delete operation is not performed, but the database is updated, the record is set to an inactive state, and the media playlist is updated, without displaying the media file that does not exist.

When scanning is started, a scanning thread is started, and all recorded information in the gallery multimedia database is inquired and cached: the storage path, the file duration, the last file modification time, whether the file is activated or not and the like are used for comparing with each piece of media file information in the media folder.

Specifically, the obtained media file information in the media folder is compared with the media file information in the media database, and whether a new addition, deletion, or modification (in this embodiment, renaming is used as one of the modifications) operation of the media file exists in the media folder is determined.

Wherein, the following method can be adopted to judge whether the media file is added, deleted and modified in the media folder:

The media data synchronous update under the application scene of adding, deleting and renaming the media files is elaborated in the following steps:

1. for the application scenario of the newly added media file:

the method comprises two situations of adding a media file and moving an SD card, wherein:

for the newly added media file: and a third party is applied to add a new media file under the media folder, under the condition, after the media file information in the media folder and the media file information in the media database are obtained through scanning, the file name, the storage path and the file duration of the media file in the media folder are matched with the corresponding records in the media database, if the matched records cannot be found in the media database, the media file is judged to be newly added in the media folder, and the storage path and the related records of the file duration of the newly added media file are inserted into the media database.

For SD card move in: because the corresponding record in the database is not deleted, the matched record can still be found during scanning, so that the media file which reappears due to the SD card moving in can be detected in the media folder through comparison, at the moment, the corresponding record of the media database is updated, and the record is set to be in an activated state.

2. For an application scenario where a media file is deleted:

the method comprises two conditions of deleting the media file and removing the SD card, wherein:

for deleting a media file: after a certain media file is deleted through a third-party application (such as a file manager), because the file does not exist, when all files under a media folder are traversed, the record does not exist, and for the situation, the corresponding record in the media database is updated, and the record is set to be in an inactivated state; the updated record at least comprises the played time length, the remark and the TAG TAG information of the deleted media file, so that the situation that the played time length, the remark, the TAG TAG and other information of the media file are deleted after the media database is updated and the played time cannot be recorded when the user plays the media again next time, and the user experience is poor is avoided.

For SD card removal: and detecting that the media file in the media folder is lost due to the removal of the SD card through comparison, and if the media file is not present, updating the corresponding record in the media database and setting the record in an inactivated state, similar to deletion.

3. For an application scenario where a media file is modified:

the third party application modifies a certain media file, for example, edits the file, so that the modification time of the file is changed, but the storage path (path) and the file duration are not changed: in this case, if it is detected through comparison that a modified media file exists in the media folder, the corresponding record in the media database is updated, and the last modification time of the file in the record is updated to the modification time of the modified media file, and other information is maintained unchanged.

4. For an application scenario of renaming a media file:

the following two cases are included:

a. media files are renamed to other file names:

the media file still exists, but the storage path changes and cannot match the existing record in the database. Matching the duration of the file with all records in the database to find a record with the same duration, updating the media database at the moment, changing the path information of the matched record into the path information of the existing file, and keeping other information unchanged. (for the extreme case, if a plurality of records with matched duration are found, the file information can be inserted into the database as a new record because whether the records are the original file or not can not be judged).

b. After deleting a certain file in the media folder, copying a new file named as the original media file name: at this time, the path information of the file is matched with the original record, the time length information is further compared, generally, the time length of the new file is not equal to the time length recorded in the media database, and the related information of the file is used as a new record and is inserted into the database. If the database has records of the same path information, the records are deleted first. (for extreme cases, when the path and duration information of the newly copied file are matched with the original records in the database, the modification time for directly updating the corresponding records in the database is the modification time of the current file).

That is, if it is detected through comparison that a renamed media file exists in the media folder and the storage path of the media file is changed, the corresponding record in the media database is updated, and the storage path of the matched record is changed into the storage path of the current media file; or, if the media file with the reserved file name but replacing the original file exists in the media folder, the related information of the media file is inserted into the media database as a new record.

And after the updating of the media database is completed, updating a media play list of the media application in real time without displaying the nonexistent media files so as to ensure the effectiveness of the media play list, synchronizing the played time length, remarks and TAG TAG information to the media database in real time, recording the played time length of the media, and continuously playing from the played position when the media is played again.

Therefore, according to the scheme, when the media files in the media folder are modified, such as the third-party application renames, deletes and modifies the media files, the SD card is moved out and the like, the media playlist and the media database are synchronized in real time, and only the existing images are displayed, so that the integrity of media information is ensured, the effectiveness of the images in the media playlist is ensured, and the user experience is improved. The overall flow chart of this embodiment can be described with reference to fig. 5 (taking a video file as an example).

Further, the updating module 203 is further configured to clear the tag information of the media file cached in the media database at preset time intervals according to preset rules.

Specifically, as shown in fig. 6, at regular intervals (e.g., 6 months), the frequency of the unused time and the used time may be determined according to whether: and clearing the mark information of the media file cached in the media database by taking the played time length, the remark and the TAG TAG information as rules.

The frequencies used are: the number of times the media file was used/the total number of times all sound recording files were used (use means that the media file was played, modified, moved, etc.).

According to the scheme, the mark information of the media files cached in the media database is regularly cleaned according to the using habits of the user, the availability of the storage space of the media database can be improved, and convenience is brought to the user to use the files through cleaning of the data.

The media playing device in the embodiment of the present invention is described above, and the media playing method in the embodiment of the present invention is described below.

As shown in fig. 7, a first embodiment of the present invention provides a media playing method, which is applied to a terminal, where a media application is installed on the terminal, and a system of the terminal is configured with a media folder, a media database, and a media playlist based on the media application, where the method includes:

step S101, when detecting the triggering of a media file scanning condition, scanning a media file in the media folder and a media database of a media application to obtain first media file information in the media folder and second media file information in the media database;

in a specific implementation, the execution main body of the method of this embodiment may be a mobile terminal such as a mobile phone, a tablet computer, a PDA, or a notebook computer, or may also be a fixed terminal such as a digital TV, a desktop computer, and the embodiment is not limited thereto. This embodiment is exemplified by a mobile phone.

Because the existing media application software depends on the media database of the system, when the media files in the media folders are modified by a third-party application other than the media application (for example, the third-party application performs operations such as renaming and modifying on the media files, or a Secure Digital Memory Card (SD Card) is moved out/in), the records and the media playlists in the media database cannot be synchronized with the files in each media folder of the system in real time. At this time, during playing, there are some records in the media database, and the corresponding media file cannot be found through the storage path, resulting in poor user experience. In addition, since the media player additionally maintains information such as the length of time the media has been played, notes, TAGs (TAGs), etc. for the media file, the user does not want the information to be deleted.

s11, scanning the file;

s13, judging whether the file is a video format file; if not, go to S14;

s14, analyzing the file header information;

Specifically, after initiating a media file scan, the media folders on the internal/external memory of the terminal are scanned in a step-by-step scan, filtering the media file format, e.g., whether the file suffix is.mp 4/. wmv, etc. audio-video format. If the format is not the format, the file header information is analyzed, and whether the mimetype of the file header information comprises a 'video/' field and the like is judged. After the media file is scanned, the file is analyzed, decoded and previewed, so that the scanning efficiency of the media file can be improved.

Step S102, comparing and analyzing the first media file information and the second media file information, and judging whether a media file in the media folder is changed, wherein the change of the media file at least comprises the addition, deletion or modification of the media file;

step S103, if the media file in the media folder is changed, correspondingly updating the media database and the media playlist of the media application, where: and when no media file exists in the media database through the recorded storage path query, the operation of deleting the corresponding record is not executed.

The present embodiment takes into account: when the third-party application performs operations such as renaming, content modification and the like on the media file or moves out/in the SD card, but the media database of the gallery is not updated in time, the problem exists at this time: and if some records in the database cannot find the corresponding media file through the storage path of the records, judging that the file does not exist. In addition, since the gallery additionally maintains parameter information such as category TAG, favorites, privacy, etc. for the media files, the user does not want to delete such information.

1. for the application scenario of the newly added media file:

2. For an application scenario where a media file is deleted:

3. For an application scenario where a media file is modified:

4. For an application scenario of renaming a media file:

the following two cases are included:

a. media files are renamed to other file names:

As shown in fig. 8, a second embodiment of the present invention provides a media playing method, which is based on the embodiment shown in fig. 7, and is different from the embodiment in that the present embodiment further includes a scheme for clearing the mark information of the media file cached in the media database according to the habit of the user.
