In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of exemplary embodiments of the present application is provided in conjunction with the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application and not exhaustive of all embodiments. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.
Example 1
As shown in fig. 1, this embodiment proposes an interaction method, which is applied to a mobile terminal, and includes:
S101, connecting the playing terminal and pushing the program stream to the playing terminal.
Specifically, in this embodiment, before the user uses the mobile terminal, the user first needs to play the video content to be watched on the mobile terminal, and a corresponding program stream is generated while playing the video content. The video content playing mode may be implemented by video application software installed in the mobile terminal, and the embodiment is not limited to the type of the video application software, and mainly uses habit of users. When the mobile terminal is connected with the playing terminal, the mobile terminal pushes the program stream of the video content being played to the playing terminal.
In this process, the mobile terminal needs to be connected to the playing terminal in advance, so that the mobile terminal can push the program stream to the playing terminal. In this embodiment, the user may search for the play terminal through the mobile terminal. It should be noted that, since the mobile terminal and the playing terminal generally adopt wireless connection, it is required to ensure that the mobile terminal and the playing terminal are located in the same network, and in the case of home use, the mobile terminal and the playing terminal are located in the same home network environment, so as to realize connection between the mobile terminal and the playing terminal. Meanwhile, the connection relation between the mobile terminal and the playing terminal needs to be identified, and the situation that the playing terminal is an equipment which can not be put on a screen or the playing terminal does not allow some mobile terminals to be connected is not excluded in the connection process. Therefore, only when the connection relationship between the playing terminal and the mobile terminal is connectable, the mobile terminal can be connected with the playing terminal, and then the mobile terminal pushes the program stream to the playing terminal.

Specifically, in this embodiment, after the playing terminal obtains the program stream pushed by the mobile terminal, the playing terminal may play the video content corresponding to the program stream in the player of the playing terminal. And the playing terminal analyzes the program stream while playing the program stream, so that the audio metadata information is obtained. The audio metadata information includes, but is not limited to, encoding information, sound objects, rendering settings, and the like. The audio metadata information in this embodiment may be three-dimensional cyanine color metadata information. The three-dimensional cyanine color sound is a three-dimensional sound technology which is independently researched and developed in China, supports mainstream three-dimensional sound coding, is compatible with mono, stereo, surround sound and three-dimensional sound, can accurately place and move sound at any position in a three-dimensional space, accurately describes the position, size, track, time and length of each sound, and can be applied to multiple scenes such as home environments, cinema environments, concert, sports events, individuals, AR/VR and vehicle-mounted scenes.
After the playing terminal analyzes and obtains the audio metadata information, the audio metadata information is sent to the mobile terminal when the mobile terminal requests. This procedure, the present embodiment is implemented under the home network-based DLNA protocol. Firstly, the embodiment defines the audio metadata information acquisition, including the extended DLNA standard interface (getPositionInfo), the newly added extended tag (audioData) and the custom parameters. And then the mobile terminal actively requests the playing terminal to send the audio metadata information through the extended DLNA standard interface (getPositionInfo) according to the preset request frequency. The request frequency defaults to one request per second, and of course, the parameter can be adjusted according to the actual situation. Finally, the playing terminal can send the audio metadata information to the mobile terminal through the extended DLNA standard interface (getPositionInfo) when the mobile terminal sends a request.

Taking the mobile terminal as a touch screen device for example, a user can input information such as characters, voices and the like through a display interface of the mobile terminal, and can also adjust related contents on the display interface in a point-touch mode.
In this embodiment, when the mobile terminal displays the interactive control content in the display interface, the user may adjust the interactive control content according to his own requirement, taking fig. 2 as an example, may adjust the comment audio, including switching of the comment type, adjustment of the volume level and the channel position, and may also adjust the sound effect, including switching of the sound effect type, adjustment of the volume level, and so on. The mobile terminal converts the adjustment of the interactive control content by the user into an operation instruction and then sends the operation instruction to the playing terminal.
When the mobile terminal sends an operation instruction to the playing terminal, the embodiment also defines the interaction of the operation instruction, including extending a DLNA standard interface (setavtransport uri) and customizing parameters in its existing tag (< CurrentURIMetaData >), taking setting and explaining as an example, the embodiment provides a data format example as follows:
Wherein, parameter name: event, type Object;
Parameter name: type, type String. The custom instruction information may correspond to an instruction type according to the audio metadata information, for example: selecting a comment (explanation), setting a position (audioLocation), setting a sound effect (soundEffect), and setting a volume.
Parameter name: value, type String. And customizing instruction information corresponding to the type. Such as: the selection of the comment (0, 1, 2), the setting of the position (value between 0 and 100), the setting of the sound effect (0, 1, 2), the setting of the volume (value between 0 and 100).
After the mobile terminal obtains the corresponding operation of the user on the display interface and converts the operation into an operation instruction, the mobile terminal sends the operation instruction to the playing terminal through an extended DLNA standard interface (SetAVTransportURI). The playing terminal can render different sound objects and set an audio-visual environment according to the operation instruction, so that different audio rendering modes of screen throwing in the home environment are realized.
According to the method, the device and the system, the audio metadata information of the program stream is obtained through the mobile terminal, the interactive control content in the audio metadata information is displayed on the mobile terminal, and then the audio parameter setting of the playing terminal is achieved through the operation of the user on the mobile terminal, so that the purpose of audio rendering while the program stream is played is achieved, and the audio-visual experience of the user is improved.
