Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
For solving the technical problem of multimedia play list operation ease deficiency in the above-mentioned conventional art mentioned, in one embodiment, spy proposes a kind of multimedia play list management system, the method can be dependent on computer program and realizes, and can run in the computer system based on von Neumann system.This computer program accessible site in the application, also can be used as independently tool-class application and runs.This computer system can be the mobile devices such as smart mobile phone, panel computer, PC, notebook computer.
In the present embodiment, this system as shown in Figure 1, comprises first terminal 10, server 20, and the second terminal 30, Fig. 2 illustrates the time program process of this system.Specifically comprise following process:
First terminal 10, for receiving the playlist item operational order of input, obtains multi-media tag that described playlist item operational order carries and the store path on described first terminal corresponding to described multi-media tag and generates synchronization request and send to described server.
First terminal 10 is the user terminal of initiating the amendment of cloud playlist, as panel computer, PC, notebook computer, smart mobile phone etc.
In the present embodiment, add or the operation such as deletion or adjustment order when user carries out outside to the multimedia selected, terminal priming inductor, receives corresponding operation requests, and operation requests is sent to server process.Wherein, playlist item refers to the class entry in playlist, as shown in Figure 3.Label 1 ~ N indicates N item, and includes the information such as multi-media tag, store path for each.Wherein, multi-media tag is generally multimedia names, and the mark as certain song is song title, certain film be designated film name etc.
Such as, the playlist of cloud music player, as shown in Figure 4, label 1 ~ 15 indicates 15 music, and includes the information such as operation, music title, singer, special edition, duration for each.
In an application scenarios, user can click the left mouse button connecting computer and choose a certain playlist item, click right button, select to delete in the menu occurred, and these operations are for computer, be exactly a series of programs, terminal priming inductor, is converted into program by the deletion action of user and sends to server.
In Another application scene, user can choose a certain playlist item by touch screen smart mobile phone playlist, again clicks the interpolation option of appearance, user terminal priming inductor, the deletion action of user is converted into program and sends to server.
User only need be clicked by external equipment or the shirtsleeve operation such as touch screen just can realize the objects such as the order of adding playlist item or deleting playlist item or adjustment playlist item.
In the present embodiment, the synchronization request that server 20 sends for receiving first terminal, obtain the playlist item that described synchronic command carries, described playlist item comprises multi-media tag and the store path on described first terminal corresponding to described multi-media tag; Obtain cloud playlist, described playlist item is carried out synchronously in described cloud playlist according to described synchronic command; Travel through the playlist item in described cloud playlist, the addressable state of the store path of the playlist item traversed described in detection, and the mapping relations creating described addressable state and described playlist item; The described cloud playlist of described addressable state be with the addition of to the second terminal described in transmission.
That is, server 20 can perform one multimedia play list management method as shown in Figure 5, the method comprises the steps:
Step S102: receive the synchronization request that first terminal sends, obtains the synchronization request playlist item of carrying, and playlist item comprises multi-media tag and the store path on first terminal corresponding to multi-media tag.
After server receives the request of intelligent terminal transmission, analysis request instruction, obtains the playlist item that instruction is corresponding.
In the present embodiment, add or the operation such as deletion or adjustment order when user carries out outside to the playlist item selected by terminal, request is also sent to server by the request of terminal equipment sensor senses, the request of the interpolation playlist item that server receiving terminal sends or deletion playlist item, gets corresponding information.Such as, in the application scenarios of an Android system, user's intelligent terminal has a music player, when user to need certain the first song searched to add in playlist and is synchronized to server, now, user can choose this head to sing by modes such as hand touch screens, and clicks interpolation button, after intelligent terminal for reception to request, start detecting sensor and corresponding instruction is sent server process.And these operate in server, be exactly one section of executable computer program, processor receives these programs and resolves, and obtains corresponding information.
Preferably, described method also comprises:
Read synchronization request, extract the timestamp that synchronization request is carried;
According to time order and function order, synchronization request is added to the tail of the queue of processing queue according to timestamp, extract synchronization request by the head of the queue of processing queue and perform the step obtaining the playlist item that described synchronization request is carried.
Timestamp is a character string normally, identifies the time at certain a moment uniquely.When being added in playlist by the multimedia item with timestamp, the sequencing of interpolation can be known.
Queue is a kind of special linear list, and special character is that it only allows to carry out deletion action in the front end of table, and carries out update in the rear end of table, and the same with stack, queue is the restricted linear list of a kind of operation.The end carrying out update is called tail of the queue, and the end carrying out deletion action is called head of the queue.When there is no element in queue, be called empty queue.
In the present embodiment, because multiple intelligent terminal can use cloud playlist simultaneously, can multimedia item be added, also can delete multimedia item, and server needs synchronous multiple user successively to operate accordingly.Server adds according to user or deletes the sequencing of timestamp in playlist item, add the playlist item of correspondence to processing queue from tail of the queue successively, then extract playlist item one by one from the head of the queue of processing queue and to add successively according to corresponding instruction or to delete.
Such as, have a LAN server to store a music playlist, user a, b, c, d are simultaneously by this playlist of respective terminal downloads.When user a with the addition of a piece of music " my skateboard ", displaying time is 12:00:00, user b with the addition of a piece of music " shoes extra large size ", displaying time is 12:00:03, user c deletes a piece of music " blue and white porcelain ", displaying time is 12:00:01, and user d also deletes a piece of music when " eliminating ", displaying time is 12:00:02, after server receives the request that respective terminal sends, according to the sequencing of identified time, successively by song " my skateboard ", " blue and white porcelain " " is eliminated " " shoes extra large size " and is inserted from the tail of the queue of processing queue, then according to the order inserted, extract " my skateboard " from head of the queue and add playlist to, " blue and white porcelain " is deleted in lists, " eliminating " is deleted in lists, and " shoes extra large size " is added in list.
Again such as, same application scenarios, user a deletes a piece of music " my skateboard " in list, displaying time is 12:00:00, and user b with the addition of this music when 12:00:01, server is still asked, according to the sequencing of time according to corresponding, first synchronization removal sends to each user, and then synchronously adds and the playlist after upgrading is sent to each user.
Step S104: obtain cloud playlist, in cloud playlist, playlist item is carried out synchronously according to synchronization request.
The playlist being stored in server end is cloud playlist, after getting corresponding information according to aforementioned server, in cloud playlist, carry out the process of information, by user operation interpolation playlist item or to delete the step of playlist item synchronous in cloud playlist.
Such as, the user e video play lists of server end that utilized panel computer to download, with the addition of a film " the fast and the furious 7 ", after server receives and adds request, add the information such as the noun of this film and storage path to cloud playlist, other users can access this sheet by list.
Step S106: the playlist item in traversal cloud playlist, detects the addressable state of the store path of the playlist item traversed, and creates the mapping relations of the state of may have access to and playlist item.
So-called traversal, refers to along certain search pattern, all does once and only does successively once access each node in tree.In the present embodiment, search pattern is the line segment that the playlist item in cloud playlist is formed by connecting from front to back, and wherein each playlist item is node.
Server accesses each playlist item in cloud playlist from front to back successively, because each playlist item also comprises store path corresponding to playlist mark, server successively test access to store path whether may have access to, and the result correspondence detected to be labeled in playlist item.
In the application scenarios of an office intranets, have on a station server and store a music playlist, one has 100 songs, and every a piece of music comprises the information such as store path of music title, singer, memory device.And per song memory address is different, the terminal being stored in user A had, the terminal being stored in user B had, what have is stored in the Internet etc.Server accesses equipment corresponding to each store path according to store path successively from front to back, when accessing First music, if inaccessible, add mark under the music title of correspondence in the play list, then continue next music of access, if still inaccessible, the mark that corresponding interpolation is same, if may have access to, then add different identification, to show difference.The music of not accessing in the same way successively in access list.
Further, described method also comprises: the addressable state periodically detecting the store path of each playlist item in described cloud playlist.
Periodically refer to go round and begin again complete repeatedly complete access, the time interval between twice adjacent complete access is called the cycle.
In same application scenarios, setting cycle=5 second, after server has traveled through all music, 5 seconds, interval, access is started successively from the beginning to the end again according to identical mode, under again marking corresponding music title according to new access result, and the mark result once traveled through before covering.
Further, the step detecting the addressable state of the store path of the playlist item traversed also comprises:
Store path to the playlist item traversed sends heartbeat packet, and whether overtimely judge to receive heartbeat packet, the addressable state of the store path of the playlist item if so, then traversed is inaccessible.
Heartbeat packet be exactly between client and server between to send the state of simple message notice the other side oneself according to certain time interval, be similar to heartbeat.That is, code sends a fix information at set intervals to client, and client receives rear reply fix information.If service end does not receive client-side information in a period of time, disconnect depending on client.Such as some communication software does not use for a long time, wonder that its state is online or off-line just needs heartbeat packet, packet receiving of regularly giving out a contract for a project.
In the present embodiment, when server accesses corresponding memory device by the store path in playlist item, heartbeat packet is sent to memory device, server message replied by memory device after receiving heartbeat packet, set one and receive the time range of replying message, if receive reply message in this time range server, now think that corresponding store path may have access to, if confiscate, then inaccessible.
Step S108: transmission with the addition of the cloud playlist of addressable state to the second terminal.
The aforementioned playlist that with the addition of corresponding mark according to access result is sent to intelligent terminal by server.Second terminal according to the mark of correspondence with this playlist of different effect plays.
In the present embodiment, 30, the second terminal is for showing the playlist item in described cloud playlist with the bandwagon effect corresponding with the addressable state of the playlist item in described cloud playlist.
As shown in Figure 1, the second terminal 30 is connected with server 20 and shares the user terminal of same cloud playlist with first terminal.Can be the mobile devices such as smart mobile phone, PC, notebook computer, panel computer equally.First terminal is equal to the second terminal effects, and meanwhile, the second terminal also can comprise the function of server.Second terminal is for showing the cloud playlist that with the addition of addressable state that server sends herein.The method of showing has multiple, can be at least one in following method:
Green for addressable multimedia item display, the multimedia item display of inaccessible is red.
Show No. two for addressable multimedia item, the multimedia item of inaccessible shows No. five fonts.
For addressable multimedia item display regular script, the multimedia item display Song typeface of inaccessible.
Only show addressable multimedia item, hide the multimedia item of inaccessible.
Further, second terminal is also for receiving play instruction, obtain the playlist item that described play instruction carries, if the addressable state of described playlist item is inaccessible, then skip current play list item in described cloud playlist, and the addressable state playing next playlist item multimedia file that to be addressable playlist item corresponding.
When use second terminal plays file, whether the second terminal can the playlist item corresponding according to the addressable condition adjudgement of mark may have access to.For the playlist item of inaccessible, the second terminal directly skips the broadcasting of this file, and continues to play next addressable playlist item.And for user, according to the difference display in the second terminal, can identify fast can played file, when user want to click arbitrarily a certain playlist item play time, only choose and once can play.
Optionally, in multimedia play list management method, server also can perform step playlist item identical for store path in described cloud playlist merged.
Such as, certain user f with the addition of a piece of music " Nan Shannan " on its mobile phone EMS memory card when 12:00:00 by smart mobile phone, after server receives and adds request, add this music to cloud playlist, this song is again added when this user is at 12:05:00, after server receives request, detect that the information of acquisition repeats, two first songs are merged.
Again such as, certain user g with the addition of a storage pictures on the internet by smart mobile phone, and user h also added same pictures afterwards, and server, according to Twice requests and detection, gets duplicate message, merges two photos.
In addition, for solving the technical problem of multimedia play list bookkeeping convenience deficiency in the above-mentioned conventional art mentioned, in one embodiment, spy proposes a kind of multimedia play list management devices, as shown in Figure 6, this device comprises: synchronization request receiver module 102, synchronization module 104, state detection module 106 and sending module 108, wherein:
