Referring to fig. 4, a flowchart of a multimedia content playing method according to another embodiment of the present invention is shown. The present embodiment is exemplified by applying the multimedia content playing method to the system shown in fig. 1. The method may include the steps of:
step 401, the vehicle-mounted host reports at least one item of information of a user account, a current position, weather, speed per hour and a navigation destination to a background server;
and the vehicle-mounted host reports at least one item of information of the user account, the current position, the weather, the speed per hour and the navigation destination to the background server at a preset time. The preset time comprises the following steps: at least one of the determined moments at predetermined time intervals after the vehicle is started, after the on-board host is started, after the multimedia APP is started.
For example, after the multimedia APP is started, the vehicle-mounted host reports the user account to the server; then, the current position and the speed per hour are reported every 1 minute. Optionally, the current location is identified by latitude and longitude.
For another example, when the driver starts navigation, the vehicle-mounted host reports the current geographic position and/or navigation destination to the server.
Correspondingly, the server receives at least one item of information of the user account, the current position, the speed per hour and the navigation destination reported by the vehicle-mounted host.
Step 402, a server acquires candidate multimedia content from at least one content source;
optionally, the at least one content source comprises: the content recommendation system comprises a first type of content source for recommending based on the preference of a user and/or a second type of content source for recommending based on a driving scene.
The first category of content sources includes: the song or the song list collected by the user account corresponding to the client, the singer concerned by the user account corresponding to the client, the individual radio station concerned by the user account corresponding to the client, the multimedia content list and the daily recommended song list.
The second category of content sources includes: at least one of the road condition scene song list, the weather scene song list and the speed scene song list. Wherein, the road condition scene song list is a song list determined according to at least one factor of the road surface type, the road surface jolting degree, the road surface congestion degree, the current position and the navigation destination, such as a mountain song list, a city song list, a jolt song list, a high-speed song list, a congestion song list, an XX city song list and an XX scenic spot song list; the weather scene song list is determined according to the weather condition of the current position; the speed scene song list is a song list determined according to the current speed per hour of the vehicle, such as a low-speed song list, a high-speed song list, a cruise song list and the like. Optionally, the road condition scene song list and the speed scene song list have an intersection.
The candidate multimedia content is the multimedia content which is interested by the user account corresponding to the client. Illustratively, the server acquires a song or a song list collected by a user account as first candidate multimedia content; the server acquires the top-ranked 10 songs in the song library of the singer concerned by the current user account as second candidate multimedia content; the server acquires the first 10 songs of the personalized radio station concerned by the current user account as third candidate multimedia content; the server acquires the first 5 songs in the multimedia content list as fourth candidate multimedia content; the server acquires the first 5 songs in the daily recommended song list as fifth candidate multimedia content; when the current road condition is an expressway, the server acquires a high-speed song list as sixth candidate multimedia content; when the weather of the current geographical position is rainy, the server acquires a rainy season song list as a seventh candidate multimedia content; and when the current speed per hour is greater than a preset threshold value, the server acquires a high-speed song list as eighth candidate multimedia content. The embodiment of the present invention does not limit how the server determines the candidate multimedia content.
Step 403, the server determines the priority of each candidate multimedia content;
optionally, the server determines the priority of each candidate multimedia content according to a preset priority policy. The pre-set priority policy may vary from one embodiment to another.
In a first possible implementation manner, the server determines the priority of the candidate multimedia content according to whether the candidate multimedia content meets a first preset condition, where the first preset condition corresponds to a content source of the candidate multimedia content, the first preset condition corresponding to each content source may be different, and each content source corresponds to at least one first preset condition. Optionally, in this implementation the priority of the candidate multimedia content remains unchanged after the determination.
In a second possible implementation manner, the server determines the priority of each candidate multimedia content in an initial state according to the preset weight of the content source corresponding to each candidate multimedia content; then, when the candidate multimedia content and/or the content source corresponding to the candidate multimedia content meet a second preset condition, the server adjusts the priority of the candidate multimedia content.
Wherein adjusting the priority of the candidate multimedia content comprises: increasing the priority of the candidate multimedia content and/or decreasing the priority of the candidate multimedia content. The present embodiment does not impose any limitation on how the server determines or adjusts the priority of the candidate multimedia content.
Step 404, the server determines at least one recommended multimedia content according to the sequence of the priority levels from high to low;
illustratively, the server determines the candidate multimedia contents ranked at the top n as the recommended multimedia contents according to the order of the priority from high to low, wherein n is a positive integer. For example, n is 20.
Step 405, the server generates transition broadcast content corresponding to the recommended multimedia content;
the method comprises the steps of generating a first transition broadcast content according to a recommendation reason of recommended multimedia content, and/or generating a second transition broadcast content according to a user comment of the recommended multimedia content, and/or generating a third transition broadcast content according to an identification or a link address of dynamic content, wherein the dynamic content is broadcast content which is related to the recommended multimedia content and changes along with time.
And for all or part of the recommended multimedia contents, the server generates first live broadcast contents according to the recommendation reason of the recommended multimedia contents.
Illustratively, the generation process of the first transition broadcast content includes the following steps:
1. generating a first transition broadcast content in a text format according to a recommendation reason for recommending the multimedia content and a preset character template;
for example, if the content source recommending the multimedia content is a song library of a singer concerned by the current user, the first transition broadcast content generated by the server in the text format is: hi, welcome in thisIn the afternoon of fine weatherComing to today's personalized stations. The first song is from your favorite singerXXIs/are as followsNot staying in winterHope you like.
Wherein the weather, time period, singer name and song name corresponding to the underlined section are the modifiable contents in the template.
For another example, if the content source recommending the multimedia content is a song or a song list collected by the current user, the server generates the first transition broadcast content in the text format as follows: the following《xxx fool》According to your collectiondon't look xxxRecommended, believes that you are not disappointed.
Wherein, the song name corresponding to the underline part is the changeable content in the template.
For another example, if the content source recommending the multimedia content is a congestion song list, the server generates the first transition broadcast content in the text format as follows:front road congestionSending you cheerfulhappyAnd congratulate your mood, and traffic jam is not a jam.
The road condition information and the song name corresponding to the underlined part are the modifiable contents in the template.
For another example, if the content source recommending the multimedia content is a multimedia content list, the server generates the first live broadcast content in the text format as follows:peak peak-peakIn (1)baby，xxxAirborne attack of diabetesNew song list of peakFirst, the1A bit.
The list name, singer name, song title and list ranking corresponding to the underlined part are contents which can be changed in the template.
2. And converting the first transition broadcast content in the text format into the first transition broadcast content in the voice format through a TTS engine.
Among them, a TTS (Text To Speech) engine is an engine for converting Text into Speech.
And for all or part of the recommended multimedia content, the server generates second transition broadcast content according to the comments of the recommended multimedia content.
Illustratively, the process of generating the second transition broadcast content includes the following steps:
1. randomly selecting one comment from the comments recommending the multimedia content as a target comment; or, obtaining a latest comment as a target comment; or, obtaining the comment with the comment word number exceeding the preset word number as a target comment;
for example, the server randomly picks one comment as a target comment: one rates the song by: the weak sound image knocked out by the old clock is gently dropped in time. Sometimes, in the evening, a flute sound is transmitted from a room on the top floor. The whistling person leans on the window window, and the window is large tulip. At the moment, if you don't love me, I can not be aware of.
2. And converting the target comment into a second transition broadcast content in a multimedia format through a TTS engine.
And for all or part of the recommended multimedia contents, the server generates third transition broadcast contents according to the identification or the link address of dynamic contents, wherein the dynamic contents are broadcast contents which are related to the recommended multimedia contents and change along with time.
Illustratively, the process of generating the third transition broadcast content includes the following steps:
and the server generates the third transition broadcast content in the text format according to the identifier or the link address of the dynamic content in the preset text format. The dynamic content is content that is related to the recommended multimedia content and that changes following a predetermined factor. The predetermined factors include: at least one of time, current geographic location of the client, weather of the client, and speed of the client.
Illustratively, dynamic content that changes with time factors includes, but is not limited to: at least one of a number of times of being collected, a number of times of being listened to, a number of times of being liked, a text comment or a voice comment, a list ranking; dynamic content that follows the current geographic location change includes, but is not limited to: a list in xx region, a ballad story in xx region, and at least one of collection times or listening times or praise times of recommended multimedia contents by users in xx region; dynamic content that follows weather changes include, but are not limited to: commenting the recommended multimedia content by the user in different weather scenes; dynamic content that follows changes in speed of time include, but are not limited to: and the user commenting on the recommended multimedia content under different speed-per-hour scenes.
For example, for the recommended multimedia content "song a", a third transition broadcast content "x people have collected this song a at present" in text format is generated. Where "song a has been collected so far" is a predetermined text format, and "x" is a link address of dynamic content. Since the collection number of song a is constantly changing with time, the link address x in the third transition broadcast content points to the latest collected number of times.
For another example, for the recommended multimedia content "song B", the third transition report content "today's weather in text format" is xx, and in such weather, someone reviews the song as follows: yy ", where" weather today is, under such weather, someone reviews the song as follows: "is a predetermined text format," xx "and" yy "are link addresses of dynamic content. Since the comments of song B are different in different weather scenes, the link addresses "xx" and "yy" in the third transition broadcast content point to constantly changing dynamic content, which is generated by the server according to a predetermined factor in real time.
The client is used for acquiring the dynamic content in the text format according to the identifier or the link address in the third transition broadcast content after receiving the third transition broadcast content, and replacing the identifier or the link address of the dynamic content in the third transition broadcast content by using the dynamic content; and then converting the third transition broadcast content in the text format into the third transition broadcast content in the multimedia format through a TTS engine.
Step 406, the server generates a recommended multimedia content sequence according to the recommended multimedia content and transition broadcast content corresponding to the recommended multimedia content;
optionally, the server sorts the recommended multimedia contents according to the priority of each recommended multimedia content; for each recommended multimedia content, when corresponding first broadcasting content is available, inserting the first broadcasting content before the recommended multimedia content; and when corresponding second transition broadcast content or third transition broadcast content exists, inserting the second transition broadcast content or the third transition broadcast content into the recommended multimedia content to obtain a recommended multimedia content sequence.
Step 407, the server sends a recommended multimedia content sequence to the client;
optionally, when the multimedia APP does not store the recommended multimedia content, the server sends a multimedia file or a multimedia stream of the recommended multimedia content to the multimedia APP; when the multimedia APP stores the recommended multimedia content, the server only needs to send the identifier of the recommended multimedia content.
Optionally, the server may generate all the contents in the recommended multimedia sequence at one time, or may generate subsequent contents in the recommended multimedia sequence while playing, which is not limited in this embodiment of the present invention. When the server generates all contents in the recommended multimedia sequence at one time, the server sends all contents in the recommended multimedia sequence to the client; and when the server generates the contents in the recommended multimedia sequence for multiple times, the server sends the contents in the recommended multimedia sequence to the client for multiple times. For example, the server sends one recommended multimedia content and the transition broadcast content corresponding to the recommended multimedia content each time, and sends the next recommended multimedia content and the transition broadcast content corresponding to the next recommended multimedia content before the client finishes playing the current recommended multimedia content and the transition broadcast content.
In step 408, the client receives the recommended multimedia content sequence sent by the server.
Correspondingly, the client receives all the contents of the recommended multimedia content sequence sent by the server at one time, or the client receives the recommended multimedia content sequence sent by the server for multiple times and receives a part of contents in the recommended multimedia content sequence every time. For example, each time the client receives one recommended multimedia content and the transition broadcast content corresponding to the recommended multimedia content, the client receives the next recommended multimedia content and the transition broadcast content corresponding to the next recommended multimedia content before the client finishes playing the current recommended multimedia content and the transition broadcast content.
And step 409, the client plays the recommended multimedia content and the transition broadcast content corresponding to the recommended multimedia content.
And the client in the vehicle-mounted host sequentially plays the recommended multimedia content and the transition broadcast content corresponding to the recommended multimedia content according to the sequence order.
Optionally, when the ith recommended multimedia content has a corresponding first transition broadcast content, the first transition broadcast content is played before the ith recommended multimedia content; and when the ith recommended multimedia content has a corresponding second transition broadcast content, the second transition broadcast content is played after the ith recommended multimedia content, wherein i is a positive integer. Certainly, the actual playing sequence of the various transition broadcast contents is not limited in this embodiment.
Optionally, when the ith recommended multimedia content has a corresponding third transition broadcast content, the client acquires the dynamic content in the text format according to the identifier or the link address in the third transition broadcast content, and replaces the identifier or the link address of the dynamic content in the third transition broadcast content by using the dynamic content; and converting the third transition broadcast content in the text format into the third transition broadcast content in the multimedia format through a TTS engine.
For example, according to the third transition broadcast content "x has x people already collected the link address" x "in this song a" at present in the text format, the number of times of acquiring the latest collection from the server is 199981 times, the "199981" is used to replace "x" in the third transition broadcast content to obtain "199921 people already collected this song a" at present, and then the "199921 people already collected this song a" in the text format is converted into the third transition broadcast content in the multimedia format by the TTS engine.
For another example, the client broadcasts the content according to the third transition in the text format, "the weather today is xx, and in such weather, someone reviews the song as follows: link addresses "xx" and "yy" in yy ", it is acquired from the server that the weather today is" light rain ", and comments about" light rain "are" raindrops slowly sprinkle on the street, you would like a first love of the year to chan? "then replace" xx "and" yy "in the third transition announcement content with dynamic content to get" today's weather is light rain, and in such weather, someone reviews the song as follows: raindrops slowly sprinkled on the street, you want to be a mani in the first love of the year? "the client would then comment the song in text format" weather today is light rain, in which case someone: raindrops slowly sprinkled on the street, you want to be a mani in the first love of the year? "convert to the third transition broadcast content in the multimedia format by the TTS engine.
