Embodiment one

Fig. 1 is the flowchart of the method for playing audio and video by a playback device provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where a smart terminal device (such as a mobile phone, a tablet computer) and a playback device are connected to a network to play audio and video, The method can be performed by a playback device (such as a smart speaker), and specifically includes the following steps:

Step 101, the playback device receives and records server login parameters sent by at least one smart terminal.

Among them, the server login parameter is a parameter containing login information obtained when the smart terminal logs in to the server, such as: server port information, current smart terminal login authentication information (smart terminal user name, password, etc.), login time information, server address information etc. The server login parameter is mainly used to log in to the server to obtain the address information of the audio and video, and then play the audio and video. For example: after the APP in the smart terminal logs in to the music server through a router or mobile network, when a certain song in the APP music list needs to be played, the URL (Uniform ResoureLocator, Uniform Resource Locator) of the song can be obtained from the music server, Further, the specific data information of the song is obtained through the URL for playing.

In this solution, the playback device can be connected with one or more smart terminals. Preferably, if the smart terminal has server login parameters, the playback device automatically receives the server login parameters of the smart terminal and records them when it is connected to the network. The smart terminal can also choose whether to send the server login parameters to the playback device according to the user's operation.

Step 102, the playback device receives and records the playlist sent by the at least one smart terminal.

Wherein, the playlist records the relevant information of the audio and video, for example, may include the name of the audio and video, singer (actor), publisher, thumbnail, and playing duration, etc. The playlist is maintained in the APP of the smart terminal, and users can perform routine operations such as adding or deleting audio and video in the playlist according to individual needs. Preferably, when the playback device and the smart terminal are connected to the network, if there is a playlist in the smart terminal, the playlist is automatically sent to the playback device, and the playback device records the playlist after receiving it. Preferably, the playlist in the playback device can be changed dynamically, and kept consistent with the playlist in the smart terminal sending the list in real time. Preferably, the user can also choose to manually send the playlist to the playback device after editing the playlist in the smart terminal.

In this solution, the playback device can be connected to one or more smart terminals at the same time. Preferably, after the playback device receives the playlist sent by the smart terminal, it can record in various ways. Exemplarily, the playback device can independently maintain the playlist corresponding to the smart terminal according to different smart terminals, or only maintain a newly received playlist in the playback device, and the previous playlist is automatically overwritten.

Step 103, the playback device obtains the address information of the audio and video to be played from the server according to the playlist and the server login parameters, and plays the audio and video.

Wherein, when playing the audio and video in the playlist, the playback device can adopt various playback methods such as sequential playback, random playback, or loop playback. When audio and video playback is required, the playback device obtains the address information of the audio and video from the server according to the audio and video to be played in the current playlist. Preferably, the address information (such as URL information) of the audio and video to be played can be obtained from the server through the sign information of the audio and video in the playlist (such as the ID3 information of the MP3 file) and the server login parameters to obtain audio and video data for audio and video playback.

In the technical solution of this embodiment, the playback device obtains the address information of the audio and video from the server according to its own playlist and the server login parameter information to play the audio and video, which solves the problem of when the smart terminal and the audio and video server are in the process of playing the audio and video. When the network connection is disconnected, or there is no network connection between the smart terminal and the playback device, the playback device cannot continuously play multiple audio and video problems, which realizes the purpose of the playback device being able to continuously play multiple audio and video when the smart terminal network connection is disconnected .

On the basis of the above technical solution, before the playback device receives and records the server login parameters sent by at least one smart terminal, it also includes: at least one smart terminal logs in to the server to obtain corresponding server login parameters; the playback device and the at least one The smart terminal is connected to the network. Wherein, the network connection mode includes Bluetooth connection, WIFI connection and the like. The smart terminal can interact with the server through the mobile network or connect to the router using the wireless network to obtain server login parameters.

When the playback device receives different server login parameters sent by the smart terminal, it will use Multiple server login parameters are recorded in a stacked manner. Similarly, different server login parameters obtained by multiple smart terminals can still be recorded in the playback device in a stacked manner according to the time when they are sent to the playback device.

Step 202, the playback device receives and records the playlist sent by the at least one smart terminal.

Step 203, the playback device obtains the address information of the audio and video from the server according to the playlist and the server login parameters at the top of the stack to play the audio and video.

Wherein, when the playback device needs to obtain the audio and video address information from the server, it reads the recorded server login parameters from the top of the stack, and obtains the address information through the server login parameters and the playlist for audio and video playback. If the server login parameter at the top of the stack obtained by the playback device is invalid, and the address information cannot be obtained through the server login parameter, then delete the current server login parameter at the top of the stack, and obtain the server login parameter at the top of the stack again. When the playback device receives a new server login parameter, the server login parameter is recorded at the top of the stack, and is used to obtain audio and video address information from the server later.

Wherein, when the smart terminal logs out of the server, the server login parameters are usually no longer available, so corresponding unavailable server login parameters are deleted in the playback device, and the data information in the stack is rearranged. On the one hand, this solution enables the playback device to use other server login parameters to obtain audio and video address information after the smart terminal logs out of the server. Even if a certain server login parameter is invalid, the playback device can still play uninterruptedly. At the same time, the server login parameters recorded in the playback device are reasonably maintained.

On the basis of the above technical solution, preferably, when the playback device needs to obtain the audio and video address information from the server, according to the size of the frequency of use of all server login parameters recorded, select the server login parameter with the highest frequency of use and the playlist. information to obtain the address information of audio and video.

On the basis of the above technical solution, preferably, when the playback device needs to obtain audio and video address information from the server, it selects the last used server login parameters and information in the playlist to obtain the audio and video address information. In this solution, the instability caused by frequent use of different server login parameters to obtain audio and video address information due to the continuous reception of new server login parameters by the playback device is avoided.

On the basis of the above technical solution, preferably, when the playback device uses the server login parameters and playlist to obtain the audio and video addresses, it records the server that uses the server login parameters to log in (the audio and video in different APP playlists can be stored correspondingly) Obtain the rate of audio and video data in different servers), when the playback device needs to obtain the audio and video address information from the server at every turn, select the server login parameters and playlist corresponding to the server with the largest audio and video transmission rate to obtain the address information. In this solution, the audio and video playback process of the playback device is optimized through reasonable selection of server login parameters, and the playback efficiency is improved.
