Audio files refer to files that store audio data, and there are many different formats. For example, a variety of formats including, but not limited to, WAV, MP3, AAC, and M4A.

Metadata may refer to data that describes the data and its environment, information that primarily describes attributes of the data, and is used to support functions such as indicating storage locations, historical data, resource lookups, file records, and the like. For example, metadata in an audio file may provide basic attributes including, but not limited to, the name, content, year, producer, etc. of the audio.

The audio metadata container may refer to a container carrying audio metadata information, for example, the name, author, content, etc. including but not limited to audio metadata may be carried in a car audio metadata container. Interaction is the meaning of the process of associating, interacting with each other. For example, the process may be a process in which the user scans the two-dimensional code, views the information, and performs operations such as voting and approval according to the information.

And S120, triggering an interactive function event for generating an audio file according to the time for triggering the interactive function in the preset interactive function information.

The time for triggering the interactive function may refer to the time for triggering the preset interactive function, for example, when the interactive function is triggered in thirteen hours and five minutes, the time for triggering the interactive function is divided into thirteen hours and five minutes. The time for triggering the interactive function may also be related to the audio playing time, how long the interaction is performed after the audio playing starts, for example, the interaction is performed at the 15 th second after the audio playing starts, and then the 15 th second after the audio playing starts is the time for triggering the interactive function.

And S130, responding to the triggered interactive function event, and displaying the interactive function corresponding to the interactive function identifier to the user for user interaction.

The interactive functions include, but are not limited to, displaying two-dimensional codes, voting activities, media information delivery, and interactive interface display and clicking. For example, a two-dimensional code presented to the user on an application program, and the user is enabled to scan the two-dimensional code to perform operations such as audio viewing, voting and praise.

The interactive function identifier is an identifier for showing the interactive function to the user. For example, the user is presented with an identification that the user can see or interact with by clicking.

TXXX: time-to-trigger seconds | Interactive capability ID

TXXX is an ID3V2 extension key, and other keys in ID3V2 may be used to hold this information.

The information divided by the vertical lines represents the time for triggering the display of the interactive capability and the ID of the interactive capability when the audio is played.

When a media player of the vehicle-mounted information entertainment system loads an audio file, an expansion key TXXX of ID3V2 is read, whether the key contains interactive capability information or not is checked, and if the label of the expansion key TXXX detects that the key contains the interactive function information, the time for triggering the interactive function and the interactive function identifier contained in the interactive function information are determined, so that the real-time detection of the interactive function information is realized.

S220, when the playing progress of the audio file reaches the time of triggering the interactive function during audio playing, sending an instruction to the vehicle-mounted information entertainment system so as to control the interactive function event triggering the audio file.

After the time for triggering the interactive function and the interactive function identifier are detected in the ID3V2, the media player should send a trigger interactive capability event to the in-vehicle infotainment system when the playing progress reaches "trigger time seconds" in the expansion key.

A media player, also called a media player, generally refers to a playing software for playing multimedia in a computer, which gathers decoders together to generate a playing function. Such as vehicle mounted media players, video media players, and media players for public transit televisions, among others.

And S230, sending an interactive function detail request carrying the interactive function identifier to the cloud server through the vehicle-mounted information entertainment system, and acquiring interactive function detail information associated with the issued interactive function identifier from the cloud server.

The cloud server is a computing server which is simple, efficient, safe, reliable and elastic in processing capacity.

The detailed interactive function information associated with the interactive function identifier may refer to information associated with scanning the two-dimensional code, for example, a download link, a file, and the like displayed after scanning the two-dimensional code; the information may refer to information associated with a page that the user can click on, for example, after the user clicks on the page, operations such as voting and approval according to a page prompt are performed.

And S240, displaying the interactive function corresponding to the interactive function identifier based on the interactive function detail information associated with the interactive function identifier so that the user can trigger interaction.

And displaying the interactive function corresponding to the interactive function identifier according to the interactive function detail information associated with the interactive function identifier, wherein the interactive capability includes but is not limited to displaying a two-dimensional code, voting, advertisement and other interactive interfaces which can be seen by the user or clicked by the user. When the two-dimensional code is displayed for the user, the user can scan the two-dimensional code, check related contents, vote and like the audio. The interactivity of the user is increased, and the viscosity of the user is improved.

According to the technical scheme of the embodiment of the invention, when the audio file is loaded, the preset time for triggering the interactive function and the interactive function identifier are read from the audio metadata container of the audio file; when the playing progress of the audio file reaches the time of triggering the interactive function during audio playing, sending an instruction to a vehicle-mounted information entertainment system so as to control an interactive function event triggering the audio file; sending an interactive function detail request carrying an interactive function identifier to a cloud server through a vehicle-mounted information entertainment system, and acquiring interactive function detail information associated with the issued interactive function identifier from the cloud server; and displaying the interactive function corresponding to the interactive function identifier based on the interactive function detail information associated with the interactive function identifier so that the user can trigger interaction, thereby realizing real-time interaction of on-demand online content audio and increasing the user viscosity.
