The method and the device for searching the caption or lyric files can send a fourth instruction for searching the caption or lyric files corresponding to the multimedia resources to the caption lyric server; receiving a caption file list or a lyric file list returned by a caption lyric server; in response to the selection operation of the target file determined according to the subtitle file list or the lyric file list, sending a fifth instruction for loading the target file to the second device, wherein the fifth instruction comprises the position information of the target file; controlling the second equipment to download the target file according to the fifth instruction; and controlling the second equipment to synchronously play the multimedia resource and the target file. Therefore, the electronic terminal can remotely control the second device to load the subtitles when playing the video resource and control the second device to load the lyrics when playing the audio resource, so that the second device synchronously plays the video resource and the subtitles and synchronously plays the audio and the lyrics, the external subtitles or lyrics are successfully realized, and the user can conveniently watch the multimedia resource.

In some embodiments, the identification may be added to the plurality of historical subtitle files or historical lyric files for a plurality of historical user control second device loading to intelligently order a list of subtitle files or lyric files. As an example, the method may further comprise the steps of:

step w), when a sixth instruction that the user determines that the selected target file is an effective file is received, adding an effective identifier to the target file;

step x), when a seventh instruction that the user determines that the selected target file is an invalid file is received, adding an invalid identifier to the target file;

and step y), sequencing the caption files in the caption file list or sequencing the lyric files in the lyric file list according to the identification type of the target file.

For the above step w), it should be noted that there are multiple files in the subtitle file list or the lyric file list, and when the user selects one of the files as the target file and determines that the selected target file is a valid file, the electronic terminal adds a valid identifier to the target file, for example, a subtitle file list is taken, and the subtitle file list is: a subtitle file 1; a subtitle file 2; a subtitle file 3, when the user 1 selects the subtitle file 2 as a target file and determines that the subtitle file 2 is an effective file, the electronic terminal adds an effective identifier to the subtitle file 2; when the user 2 selects the subtitle file 2 as the target file and determines that the subtitle file 2 is a valid file, the electronic terminal adds a valid identifier to the subtitle file 2.

For the step x), for example, when the user selects one of the files as the target file and determines that the selected target file is an invalid file, such as a scrambled code or a time scrambled sequence, the electronic terminal may add an invalid identifier to the target file, for example, because the subtitle file list is: a subtitle file 1; a subtitle file 2; and the subtitle file 3, when the user 3 selects the subtitle file 1 as the target file and determines that the subtitle file 1 is an invalid file, the electronic terminal adds an invalid identifier to the subtitle file 1.

For the step y), it should be noted that the caption library used in the present application is provided by a "shooter web", the song library is provided by the lyrics of the cool dog, and the records of the effective use and the ineffective use of the target file by the user are both sent to the electronic terminal for evaluating the target caption file and performing intelligent sorting. Illustratively, the list of subtitle files with respect to the subtitle file, the identification category, and the number of identification categories, which are previously established according to the history data, is as follows:

TABLE 3

Subtitle file	Identification type	Number of identification types
			Subtitle file 1	Invalid mark	1

In addition, in order to avoid the problem of popularity imbalance, the situation that the target files with high popularity are closer to the top of the list is prevented, namely, more and more effective identifications are possessed by the target files, and new subtitle files or lyric files are prevented from being recommended to the user, and the popularity value is corrected by adopting a forgetting function, namely, the effective identifications possessed by the target files are corrected.

Specifically, the implementation of this embodiment mainly includes three classes, subtitleontrolservice, SubtitleUtil, and Subtitle. The Subtitle class is used to describe the basic attributes of a Subtitle file, including four attributes of ID, Subtitle file name, Subtitle file URL address and Subtitle file popularity indicator.

The subtitle control service class is used for providing remote control service for intelligent recommendation of subtitles, and the method searchSubs () is used for searching all subtitle files conforming to the specified video files and sequencing the searched subtitle files according to a popularity recommendation algorithm designed by the system; the method sendsusurltophone () is used to return the intelligently recommended subtitle file result to the electronic terminal.

The subtitle class is used for realizing specific operations in subtitle intelligent recommendation, and the getInternetSubs () mainly calls a subtitle API provided by a 'shooter net' to acquire a subtitle file according to a video name; the method doSort () is used for sequencing the acquired multiple subtitle files according to the popularity indexes; the methods getsusource () and updateresource () are used to acquire and update the popularity index value of the subtitle file, respectively. And after the electronic terminal acquires the URL of the subtitle file, transmitting the URL to second equipment.

In the embodiment of the application, when a sixth instruction that a user determines that a selected target file is an effective file is received, an effective identifier is added to the target file; when a seventh instruction that the user determines that the selected target file is an invalid file is received, adding an invalid identifier to the target file; and sequencing the caption files in the caption file list or sequencing the lyric files in the lyric file list according to the identification types of the target files. Therefore, the electronic terminal can intelligently sort the subtitle file list or the lyric file list through a popularity recommendation algorithm and correct the popularity value through a forgetting function so as to update the subtitle file list or the lyric file list at regular time.

In some embodiments, as an example, the step s) may include the steps of:

step s1), receiving the caption file list or the lyric file list which is sorted according to the identification type and returned by the caption lyric server.

step z5), the multimedia resource is encrypted according to the advanced encryption standard, and the encrypted multimedia resource is obtained.

It should be noted that the symmetric encryption has a very fast encryption speed, and is very suitable for the application environment when the symmetric encryption is used for frequently sending data, so the embodiment of the present application uses the advanced encryption standard (i.e. AES encryption algorithm) to encrypt and decrypt the interactive information between multiple devices, and the specific encryption and decryption processes are as follows:

step z51), the sender uses the AES encryption function, sets the KEY of the AES encryption function as KEY, encrypts the plaintext to be transmitted according to the KEY to obtain encrypted ciphertext, and then transmits the ciphertext in the network, for example, to the second device, wherein the sender may be the electronic terminal itself, or the first device, and so on.

Step z52), after the receiving party receives the ciphertext, the receiving party decrypts the received ciphertext by using the AES decryption function according to the KEY KEY to obtain the corresponding plaintext.

In some embodiments, the first device may be controlled to send the encrypted multimedia resource to the second device according to a real-time streaming protocol. As an example, the step of controlling the first device to transmit the multimedia resource to the second device after the pairing connection is completed in step S120 may include the following steps:

step z6), the first device is controlled to send the encrypted multimedia resource to the second device after the pairing connection is completed according to the real-time streaming protocol.

It should be noted that, for transmitting multimedia resources between multiple devices, the application adopts a real-time streaming protocol, that is, RTSP, and a specific implementation method using RTSP transmission is as follows:

step z61), the headrest screen terminal sends an OPTION request to the central control screen terminal or the electronic terminal, and inquires about which methods are available in the central control screen terminal or the electronic terminal, and the central control screen terminal or the electronic terminal responds to the message and includes all available methods;

step z62), the headrest screen terminal sends a DESCRIBE request to the central control screen terminal or the electronic terminal to request to acquire media initialization description information provided by the central control screen terminal or the electronic terminal;

step z63), the headrest screen terminal sends a SETUP request to the central control screen terminal or the electronic terminal, a session is established with the central control screen terminal or the electronic terminal, the central control screen terminal or the electronic terminal establishes the session and returns a session identifier and related session information;

step z64), the headrest screen terminal sends a PLAY request to the central control screen terminal or the electronic terminal to request to PLAY the multimedia file, and the central control screen terminal or the electronic terminal responds to the request information and starts to send the streaming media data;

In addition, considering that the network condition is constantly changing, the embodiment can also realize the flow transmission dynamic code adaptation, and a common flow control algorithm is used and is based on the flow control algorithm with constant multiplicative increase and multiplicative decrease. Specifically, the integrated VLC open source player supports RTSP data stream, and implements I, P frame processing. Using Threshold as a ThresHold value of a packet loss rate to judge whether the current network sends congestion, and when the packet loss rate is greater than Threshold, considering that the network congestion is found and reducing the sending rate to reduce the packet loss; when the packet loss rate is far less than threshhold, the network condition is considered to be better, and the sending rate needs to be increased, so that the utilization rate of the network bandwidth is increased.

The implementation of the embodiment mainly includes six classes of RtspServer, requestlisterner, WorkThread, Request, Response and Session. The RtspServer realizes an RTSP server, is used for realizing streaming service, and comprises initialization information, calling a working thread to perform streaming transmission, monitoring information such as request, calculating packet loss rate and dynamically adjusting transmission code rate; the RequestListener class is a monitor used by the RtspServer and can be used for monitoring RTSP message information; the WorkThread type is a working thread for executing streaming transmission, is used for analyzing a request from a client and returning response information to the client, and controls session; request and Response are classes of information that define Request information and responses; session implements specific control of the data stream, including setting a dynamically changing transmission rate to the video stream.

According to the embodiment of the application, the multimedia resource can be encrypted according to the advanced encryption standard to obtain the encrypted multimedia resource, so that the multimedia resource can be encrypted through the advanced encryption standard, the security of transmitting the multimedia resource is improved, the transmission delay of sending a high-quality video to the second equipment is reduced, and the user experience is improved.

Fig. 2 is a schematic flowchart of a multi-device playing method based on an intelligent cabin according to an embodiment of the present application. The method is applied to the electronic terminal, and a second graphical user interface is provided through other terminals except the terminal, wherein the second graphical user interface comprises a first option corresponding to first equipment and a second option corresponding to second equipment; as shown in fig. 2, the method includes:

step S210, responding to selection operation aiming at a first option and a second option, and respectively carrying out pairing connection with a first device and a second device;

step S220, obtaining the playing information of the second equipment aiming at the multimedia resource after the pairing connection is completed;

and step S230, controlling the second device to change the playing information.

For the step S210, it should be noted that, after the electronic terminal 1 is paired and connected to the first device and the second device, the local multimedia resource or the multimedia resource of the first device may be sent to the second device, and the second device is controlled to play the multimedia resource, meanwhile, other electronic terminals such as the electronic terminal 2 and the electronic terminal 3 may also be paired and connected to the first device and the second device, and the electronic terminal 2 and the electronic terminal 3 may also access the multimedia resource on the first device, and then send the local multimedia resource or the multimedia resource of the first device to the second device.

For the step S220, the electronic terminal 2 obtains the progress information that the second device is playing the multimedia resource exemplarily, where the progress information is, for example: the total length of time for the multimedia asset is 30 minutes, playing to the 10 th minute.

For the above step S230, exemplarily, the electronic terminal 2 controls the second device to modify the playing information, that is: the second device may be controlled to pause playing the multimedia asset, or to fast forward the progress of playing the multimedia asset, etc.

The method and the device can respond to selection operation aiming at a first option and a second option, and carry out pairing connection with a first device and a second device respectively; acquiring playing information of the second equipment aiming at the multimedia resource after the pairing connection is completed; and controlling the second equipment to change the playing information. Therefore, the plurality of electronic terminals can acquire the playing information of the second equipment and further control the second equipment to change the playing information, so that the playing information of the second equipment can be controlled by a plurality of users conveniently, the technical problem of lower comprehensive use convenience of the plurality of equipment related to the cabin is solved, and the user experience is improved.

In addition, on the basis of the above embodiment, the asynchronous message queue is also used in the present application, and in the actual use process, a plurality of electronic terminals may establish connection with the same headrest screen terminal, and the plurality of electronic terminals may perform information interaction with the headrest screen terminal at the same time, which may cause a certain degree of concurrency problem. In addition, when the electronic terminal sends an instruction to the headrest screen terminal, the headrest screen terminal needs to perform some time-consuming operations, such as downloading subtitles, acquiring video, and the like, which may cause information loss if single-thread execution is adopted. In order to solve the above problem, the present application employs an asynchronous message queue.

Specifically, in the application, an interactive instruction sent by the electronic terminal to the headrest screen terminal can enter the message queue at first instead of being directly sent to the service processing system, the manner allows no dependency between the sending end of the electronic terminal and the receiving end of the headrest screen terminal, after the sender sends the message, the next message sending of the sender cannot be affected no matter how long the service needs to be processed, the service processing system takes the message from the message queue in a polling manner and processes the service, and time-consuming tasks in the message queue can be executed concurrently. Therefore, information loss caused by excessive instructions sent by the electronic terminal can be avoided, and the processing efficiency is improved.

On the basis of the above embodiment, the present application further uses a network disconnection notification policy, specifically, the network disconnection notification policy includes: when the headrest screen terminal and/or the central control screen terminal leave the local area network, if the electronic terminal does not know the information of disconnection of the headrest screen terminal and/or the central control screen terminal, the information of the headrest screen terminal and/or the central control screen terminal is still displayed for a user, and troubles are brought to the use of the user. Therefore, the method adopted by the application is that when the software of the headrest screen terminal and/or the central control screen terminal is closed, the message of leaving is told to the electronic terminal, and it is worth noting that if the equipment is suddenly powered off, the network is disconnected and the like, the message of leaving of the headrest screen terminal and/or the central control screen terminal cannot be transmitted to the electronic terminal, so that the electronic terminal also needs to send broadcast messages regularly to judge whether the headrest screen terminal and/or the central control screen terminal are online or not, if the headrest screen terminal and/or the central control screen terminal are online, the updating is not carried out, and if the equipment is offline, the equipment display list needs to be updated. In order to save self and network resources, the timing broadcast is activated only when the user is in the interface of the device connection, and the timing broadcast is closed when the user leaves the interface. Therefore, whether the first device, the second device and other devices are online or not can be timely discovered through the network disconnection notification strategy, and the online condition of the devices can be timely notified to a user.
