Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In order to solve the above-mentioned technical problem of insufficient convenience in the operation of multimedia playlists in the traditional technology, in one embodiment, a multimedia playlist management system is proposed, the method can be realized by relying on computer programs, and can run on On the computer system of von Neumann system. The computer program can be integrated in the application, or run as an independent utility application. The computer system may be a mobile device such as a smart phone, a tablet, a personal computer, a laptop, or the like.

In this embodiment, as shown in FIG. 1 , the system includes a first terminal 10 , a server 20 , and a second terminal 30 . FIG. 2 shows the sequence process of the system. Specifically include the following processes:

The first terminal 10 is used to receive the input playlist item operation instruction, obtain the multimedia identification carried by the playlist item operation instruction and the storage path corresponding to the multimedia identification on the first terminal to generate a synchronization request and send it to the said server.

The first terminal 10 is a user terminal that initiates modification of the cloud playlist, such as a tablet computer, a personal computer, a notebook computer, a smart phone, and the like.

In this embodiment, when the user performs operations such as adding or deleting externally or adjusting the order of the selected multimedia, the terminal activates the sensor, receives the corresponding operation request, and sends the operation request to the server for processing. Wherein, the playlist item refers to the category entry in the playlist, as shown in FIG. 3 . Numbers 1 to N indicate that there are N items, and each item includes information such as multimedia identifiers and storage paths. Wherein, the multimedia identifier is usually a multimedia name, for example, the identifier of a certain piece of music is the name of the song, and the identifier of a certain movie is the name of the movie.

For example, the playlist of the cloud music player, as shown in FIG. 4 , numbers 1 to 15 represent 15 items of music, and each item includes information such as operation, music title, singer, album, and duration.

In an application scenario, the user can click the left button of the mouse connected to the computer to select a certain playlist item, click the right button, and select delete in the menu that appears, and these operations are a series of programs for the computer, and the computer terminal starts The sensor converts the user's deletion operation into a program and sends it to the server.

In another application scenario, the user can select a certain playlist item in the playlist of the smartphone on the touch screen, click the add option that appears again, and the user terminal activates the sensor to convert the user's deletion operation into a program and send it to the server.

Users only need to perform simple operations such as clicking or touching the screen on an external device to achieve purposes such as adding playlist items, deleting playlist items, or adjusting the order of playlist items.

In this embodiment, the server 20 is used to receive the synchronization request sent by the first terminal, and obtain the playlist item carried by the synchronization command, where the playlist item includes the multimedia identifier and the multimedia identifier corresponding to the A storage path on a terminal; obtain a cloud playlist, and synchronize the playlist item in the cloud playlist according to the synchronization instruction; traverse the playlist item in the cloud playlist, and detect that the traversed to The accessible state of the storage path of the playlist item, and create a mapping relationship between the accessible state and the playlist item; send the cloud playlist with the accessible state added to the second terminal.

That is to say, a kind of multimedia playlist management method as shown in Figure 5 can be executed on the server 20, and the method includes the following steps:

Step S102: Receive a synchronization request sent by the first terminal, and obtain a playlist item carried in the synchronization request. The playlist item includes a multimedia identifier and a storage path corresponding to the multimedia identifier on the first terminal.

After receiving the request sent by the smart terminal, the server parses the request instruction and obtains the playlist item corresponding to the instruction.

In this embodiment, when the user performs external operations such as adding or deleting or adjusting the order of the selected playlist items through the terminal, the sensor of the terminal device senses the request and sends the request to the server, and the server receives the addition or deletion of the playlist item sent by the terminal. The request for the playlist item obtains the corresponding information. For example, in an Android system application scenario, the user's smart terminal has a music player. When the user needs to add a searched song to the playlist and synchronize it to the server, the user will touch the screen with his hand Select the song in other ways, and click the Add button. After receiving the request, the smart terminal starts the sensor and sends the corresponding command to the server for processing. For the server, these operations are an executable computer program, and the processor receives and analyzes these programs to obtain corresponding information.

Preferably, the method also includes:

Read the synchronization request and extract the timestamp carried by the synchronization request;

Adding the synchronization request to the tail of the processing queue in chronological order according to the timestamp, and extracting the synchronization request from the head of the processing queue to perform the step of obtaining the playlist items carried by the synchronization request.

A timestamp is usually a sequence of characters that uniquely identifies a moment in time. When multimedia items with time stamps are added to the playlist, the order in which they are added can be known.

A queue is a special linear table, which is special in that it only allows deletion operations at the front end of the table, and insert operations at the back end of the table. Like a stack, a queue is a linear table with limited operations. The end of the insertion operation is called the end of the team, and the end of the deletion operation is called the head of the team. When there are no elements in the queue, it is called an empty queue.

In this embodiment, since multiple smart terminals can use the cloud playlist at the same time, multimedia items can be added, and multimedia items can also be deleted, but the server needs to synchronize the corresponding operations of multiple users in sequence. The server adds the corresponding playlist items to the processing queue sequentially from the end of the queue according to the sequence of timestamps in the playlist items added or deleted by the user, and then extracts the playlist items one by one from the queue head of the processing queue and adds them sequentially according to the corresponding instructions or delete.

For example, a local area network server stores a music playlist, and users a, b, c, and d download the playlist through their respective terminals at the same time. When user a added a piece of music "My Skateboard Shoes", the display time is 12:00:00, user b added a piece of music "shoes extra large", the display time is 12:00:03, user c deleted A piece of music "Blue and White Porcelain", the display time is 12:00:01, and user d also deletes a piece of music "Elimination", the display time is 12:00:02, after the server receives the request from the respective terminal , insert the songs "My Skateboard Shoes", "Blue and White Porcelain", "Elimination" and "Shoes Extra Large" from the end of the processing queue according to the order of the identification time, and then extract "My Skateboard Shoes" to the playlist, "Blue and White Porcelain" was removed from the list, "Knockout" was removed from the list, and "Shoe King Size" was added to the list.

For another example, in the same application scenario, user a deletes a piece of music "My Skateboard Shoes" in the list, and the displayed time is 12:00:00, while user b adds this music at 12:00:01, Still according to the corresponding request, the server first synchronously deletes and sends to each user according to the order of time, and then synchronously adds and sends the updated playlist to each user.

Step S104: Obtain the cloud playlist, and synchronize the playlist items in the cloud playlist according to the synchronization request.

The playlist stored on the server side is the cloud playlist. After obtaining the corresponding information according to the aforementioned server, the information is processed in the cloud playlist, that is, the steps of adding or deleting playlist items operated by the user are played on the cloud. synchronized in the list.

For example, user e downloads a video playlist on the server side using a tablet computer, and adds a movie "Speed and Furious 7". Other users can access this slice through the list.

Step S106: Traverse the playlist items in the cloud playlist, detect the accessible state of the storage path of the traversed playlist item, and create a mapping relationship between the accessible state and the playlist item.

The so-called traversal refers to visiting each node in the tree once and only once along a certain search route. In this embodiment, the search route is a line segment formed by connecting playlist items in the cloud playlist from front to back, and each playlist item is a node.

The server accesses each playlist item in the cloud playlist sequentially from front to back. Since each playlist item also contains the storage path corresponding to the playlist identifier, the server sequentially detects whether the accessed storage path is accessible, and sends the detected result Correspondence is marked on the playlist item.

In an application scenario of an office LAN, a server stores a music playlist with a total of 100 pieces of music, and each piece of music includes information such as the music title, singer, and storage path of the storage device. And each music storage address is different, some are stored in the terminal of user A, some are stored in the terminal of user B, some are stored in the Internet and so on. The server accesses the device corresponding to each storage path from front to back according to the storage path. When accessing the first music, if it is not accessible, add a logo under the corresponding music title in the playlist, and then continue to access the next music. If it is still inaccessible, add the same logo correspondingly; if it is accessible, add a different logo to show the difference. In the same way, unaccessed music in the list is accessed sequentially.

Further, the method further includes: periodically detecting the accessible state of the storage path of each playlist item in the cloud playlist.

Periodicity refers to completing multiple complete visits over and over again, and the time interval between two adjacent complete visits is called a period.

In the same application scenario, set the period = 5 seconds. After the server traverses all the music, the interval is 5 seconds, and then start accessing in the same way from the beginning to the end, and re-mark the corresponding music according to the new access results. heading, and overwrites the markup results from the previous pass.

Further, the step of detecting the accessible state of the storage path of the traversed playlist item also includes:

Send a heartbeat packet to the storage path of the traversed playlist item, and judge whether receiving the heartbeat packet has timed out, and if so, the accessible state of the traversed playlist item's storage path is inaccessible.

The heartbeat packet is to send simple information between the client and the server at a certain time interval to inform the other party of its own status, similar to heartbeat. That is to say, the code sends a fixed message to the client at regular intervals, and the client replies with a fixed message after receiving it. If the server does not receive client information within a period of time, the client will be considered disconnected. For example, if some communication software is not used for a long time, if you want to know whether its status is online or offline, you need a heartbeat packet, and send and receive packets at regular intervals.

In this embodiment, when the server accesses the corresponding storage device through the storage path in the playlist item, it sends a heartbeat packet to the storage device, and the storage device replies to the server with a message after receiving the heartbeat packet, and sets a time range for receiving the reply message , if the server receives a reply message within this time range, it considers that the corresponding storage path is accessible at this time, and if it does not receive it, it is inaccessible.

Step S108: sending the cloud playlist with added accessible state to the second terminal.

The server sends the aforementioned playlist to which the corresponding identifier is added according to the access result to the smart terminal. The second terminal displays the playlist with different effects according to the corresponding identifier.

In this embodiment, the second terminal 30 is configured to display the playlist items in the cloud playlist with a display effect corresponding to the accessible state of the playlist items in the cloud playlist.

As shown in FIG. 1 , the second terminal 30 is a user terminal connected to the server 20 and sharing the same cloud playlist with the first terminal. The same can be mobile devices such as smartphones, PCs, laptops, tablets, etc. The effect of the first terminal is equivalent to that of the second terminal, and at the same time, the second terminal may also include a server function. Here, the second terminal is used to display the cloud playlist sent by the server and added with an accessible state. There are many ways to display, which can be at least one of the following methods:

Displays green for accessible multimedia items and red for inaccessible multimedia items.

The number two is displayed for accessible multimedia items, and the font number five is displayed for inaccessible multimedia items.

The accessible multimedia items are displayed in italics, and the inaccessible multimedia items are displayed in Times New Roman.

Only show accessible multimedia items, hide inaccessible multimedia items.

Further, the second terminal is also used to receive the play instruction, acquire the playlist item carried by the play instruction, and skip the current playlist in the cloud playlist if the accessible status of the playlist item is inaccessible. item, and play the multimedia file corresponding to the playlist item whose accessibility status of the next playlist item is accessible.

When using the second terminal to play the file, the second terminal will judge whether the corresponding playlist item is accessible according to the accessible state of the mark. For an inaccessible playlist item, the second terminal directly skips playing the file and continues to play the next accessible playlist item. As for the user, according to the difference display on the second terminal, the playable file can be quickly identified, and when the user wants to click on a certain playlist item to play, it only needs to be selected once to play.

Optionally, in the multimedia playlist management method, the server may also execute the step of merging playlist items with the same storage path in the cloud playlist.

For example, a user f adds a piece of music "Nanshannan" on the memory card of his mobile phone at 12:00:00 through his smartphone. After receiving the adding request, the server adds the music to the cloud playlist. When the user Add this song again at 12:05:00. After receiving the request, the server detects that the obtained information is duplicated and merges the two songs.

For another example, a user g adds a picture stored on the Internet through a smartphone, and later user h also adds the same picture. The server obtains duplicate information based on two requests and detections, and merges the two pictures.

In addition, in order to solve the technical problem of insufficient convenience of multimedia playlist management in the traditional technology mentioned above, in one embodiment, a multimedia playlist management device is proposed, as shown in Figure 6, the device includes: Synchronization request receiving module 102, synchronization module 104, state detection module 106 and sending module 108, wherein:

A sending module 108, configured to send the cloud playlist added with the accessible state to a second terminal, and the second terminal is configured to match the accessible state of the playlist items in the cloud playlist The corresponding display effect displays the playlist items in the cloud playlist.

Optionally, the state detection module 106 is also used for:

Periodically detect the accessible state of the storage path of each playlist item in the cloud playlist.

Further, the state detection module 106 is also used for:

Sending a heartbeat packet to the storage path of the traversed playlist item, and judging whether receiving the heartbeat packet has timed out, and if so, the accessible state of the traversed playlist item storage path is inaccessible.

Optionally, as shown in FIG. 6 , the device further includes a playlist item merging module 110 for merging playlist items with the same storage path in the cloud playlist.

Optionally, the synchronization request receiving module 102 is also used for:

reading the synchronization request, and extracting the timestamp carried by the synchronization request;

Adding the synchronization request to the tail of the processing queue in chronological order according to the timestamp, and extracting the synchronization request from the head of the processing queue to perform the step of obtaining the playlist items carried by the synchronization request.
