[0002] Internet of Vehicles services have gradually entered the lives of users. The in-car entertainment system is a medium for providing services to users, providing users with an in-car auditory experience and meeting their music listening needs while driving.

[0003] At present, the way of playing music through an external USB flash drive in the in-car entertainment system can no longer meet the user's demand for rich and high-quality music. Online music has gradually been used in the in-car scene. However, online music involves problems such as traffic consumption during the loading process and cache storage after loading. Under the current 4G network state, the peak network speed can usually reach 100Mbps, that is, the transmission speed per second is 12.5MB. If 10MB of music is cached, the entire music can be cached within 1s. Under the 5G network, the speed will be even faster.

[0004] However, the traffic of the in-car entertainment system is less than that of mobile smart devices, and the cache space is relatively small. If the entire song is cached every time the user clicks to play, it will lead to a waste of traffic and cache space resources when the user switches songs. Summary of the invention

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0028] Embodiment 1

[0029] Figure 1 This is a flow chart of a music caching method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where music is cached during music playback. The method can be executed by a music caching device, which can be implemented in the form of software and / or hardware. The hardware can be an electronic device. Optionally, the electronic device can be a mobile terminal, a vehicle-mounted terminal, etc.

[0030] like Figure 1 The method of this embodiment specifically includes the following steps:

[0031] S110: When a music playing instruction is received, determine whether the target music corresponding to the music playing instruction already exists in the cache list.

[0032] The music playing instruction may be an instruction for playing music. The target music may be the music that is currently desired to be played. The cache list may be a list of music corresponding to each cached data.

[0033] Specifically, when a music playing instruction is received, the music playing instruction is parsed to determine the target music contained in the music playing instruction. In the cache list, it is searched whether the target music exists to determine whether there is cached data corresponding to the target music in the cache space.

[0034] Optionally, when the user wants to play target music, the user can trigger the target music by selecting a triggering method and generate a music playing instruction corresponding to the target music.

[0035] S120: If not, cache the target music according to a preset initial cache ratio corresponding to the target music, and play the cached target music.

[0036] The preset initial cache ratio may be a pre-set cache ratio, such as 10% or 20% of the target music, etc., and may be adjusted according to actual needs.

[0037] Specifically, if the target music does not exist in the cache list, it indicates that the cache space does not store the cached data corresponding to the target music, and needs to be cached. At this time, the target music can be preliminarily cached according to the preset initial cache ratio corresponding to the target music, and the target music can be played according to the cached data.

[0038] S130: Cache the target music according to the current playing progress of the target music, the current cache ratio, and the preset subsequent cache ratio.

[0039] The current playing progress may be the proportion of the target music currently being played. The current cached proportion may be the proportion of the target music currently cached. The preset subsequent cache proportion may be the proportion of the target music that can be cached in the next stage.

[0040] Specifically, during the process of playing the target music, the current playing progress of the target music is obtained, and the current cache ratio is determined. Then, when the current playing progress reaches the condition for continuing to cache, the cache of the preset subsequent cache ratio is performed according to the current cached ratio.

[0041] Exemplarily, when the current playback progress of the target music reaches the preset progress, it can indicate that there is a need to continue caching the target music. At this time, the current cached ratio can be determined to determine whether the current cached ratio has reached the preset initial cache ratio. If so, the target music cache of the next preset subsequent cache ratio can be continued based on the preset initial cache ratio. If not, the cache can be cached to the preset initial cache ratio based on the current cached ratio, and then the preset subsequent cache ratio can be continued to be cached. It can also be cached to the preset initial cache ratio based on the current cached ratio, and at the same time, cache is performed according to the preset subsequent cache ratio based on the preset initial cache ratio, that is, cached simultaneously.

[0042] On the basis of the above embodiment, after determining whether the target music corresponding to the music playing instruction already exists in the cache list, it also includes: if so, playing according to the target music in the cache list.

[0043] Specifically, if the target music exists in the cache list, it indicates that the cache space has cached data corresponding to the target music, and no cache is required. At this time, the cached data corresponding to the target music in the cache space can be retrieved according to the target music in the cache list and played.

[0044] The technical solution of the embodiment of the present invention is as follows: when a music playing instruction is received, it is determined whether the target music corresponding to the music playing instruction already exists in the cache list; if not, the target music is cached according to a preset initial cache ratio corresponding to the target music, and the cached target music is played; the target music is cached according to the current playing progress of the target music, the current cached ratio and the preset subsequent cache ratio, thereby solving the problem of wasting storage space and traffic caused by caching the entire song every time the play is clicked and being unable to cache according to the user's listening situation, and achieving the technical effect of caching the target music while playing, saving traffic and cache space.

[0045] Embodiment 2

[0046] Figure 2 This is a flowchart of a music caching method provided in Embodiment 2 of the present invention. This embodiment is based on the above embodiments. For the subsequent caching method and the caching method when switching songs, please refer to the technical solution of this embodiment. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here.

[0047] like Figure 2 The method of this embodiment specifically includes the following steps:

[0048] S210: When a music playing instruction is received, determine whether the target music corresponding to the music playing instruction already exists in the cache list.

[0049] S220: If not, cache the target music according to a preset initial cache ratio corresponding to the target music, and play the cached target music.

[0050] S230: If the difference between the current cached ratio and the current playback progress reaches a preset subsequent cache threshold, a cache start point is determined according to the current cached ratio, and the target music is cached according to the cache start point and the preset subsequent cache ratio.

[0051] The preset subsequent cache threshold may be a preset value for triggering the next cache. The cache starting point may be a cache starting position of a preset subsequent cache ratio.

[0052] Specifically, if the difference between the current cached ratio and the current playback progress reaches a preset subsequent cache threshold, a cache start point corresponding to the current cached ratio is determined, and then cache is started from the cache start point, and the cache ratio is a preset subsequent cache ratio.

[0053] It should be noted that when performing subsequent caching for the first time, the preset initial cache ratio may be determined as the cache starting point. When performing subsequent caching for the second time or thereafter, the corresponding preset initial cache ratio and preset subsequent cache ratio may be determined according to the current cached ratio, and the cache starting point may be determined.

[0054] Exemplarily, the preset initial cache ratio is 20%, and the preset subsequent cache ratio is 10%. If the difference between the current cached ratio and the current playback progress reaches the preset subsequent cache threshold, the current cached ratio is 20%, and the preset initial cache ratio of 20% can be used as the cache starting point. If the difference between the current cached ratio and the current playback progress reaches the preset subsequent cache threshold, the current cached ratio is 50%, and the cache starting point can be determined to be 50%, that is, 20% + 3 × 10%. If the current cached ratio does not reach the cache starting point, the cache starting point corresponding to the current cached ratio can be determined. For example, if the current cached ratio is 48%, the cache starting point can be 50%.

[0055] It should be noted that if the current cached ratio has not reached the cache starting point, you can wait until the current cached ratio reaches the cache starting point and start subsequent caching from the cache starting point. You can also simultaneously perform caching between the current cached ratio and the cache starting point and subsequent caching starting from the cache starting point.

[0056] S240: If a song switching instruction is received during the process of playing the target music, the playing and caching of the target music are stopped, the music to be played is determined according to the play list, and the music to be played is played according to the cache list.

[0057] The song switching instruction may be an instruction for switching from the target music to the music to be played. The playlist may be a list of music to be played, such as a list of songs to be played, which is a list of music that the user wants to play. The music to be played may be the next music to be played corresponding to the target music.

[0058] Specifically, if a song switching instruction is received during the process of playing the target music, it indicates that the user wants to stop playing the target music and wants to play the music to be played. At this time, the playing and caching of the target music are stopped. Then, the next music corresponding to the target music in the play list is determined to be the music to be played, and the music to be played is searched in the cache list. If it is found, it is played. If it is not found, it is played while caching. The playing and caching method for the music to be played can be the same as that for the target music.

[0059] It should be noted that if the music to be played is not in the playlist, for example, the user triggers a piece of music that is not in the playlist, the music triggered by the user can be added to the playlist and determined as the music to be played.

[0060] It should also be noted that the music in the playlist can be played in a single loop, sequential play, random play, etc., and the music to be played corresponding to the target music can be determined based on the play mode.

[0061] S250: When the current playing progress reaches a preset next song cache threshold, obtain the music to be played corresponding to the target music in the playlist, and cache the music to be played according to a preset initial cache ratio to be played.

[0062] The next cache threshold may be a playback progress value that triggers caching of the music to be played. The preset initial cache ratio to be played may be a cache ratio for pre-caching the music to be played when playing the target music.

[0063] Specifically, when the current playing progress reaches the preset next cache threshold, it indicates that the target music is about to be played, and the next music can be cached in advance. The music to be played corresponding to the target music is determined according to the playlist, and the music to be played is cached at a preset initial cache ratio.

[0064] It should be noted that the values ​​of the preset initial buffer ratio to be played and the preset initial buffer ratio can be the same or different and can be set according to actual needs. Usually, the preset initial buffer ratio to be played is less than or equal to the preset initial buffer ratio.

[0065] In order to expand the cache list so that the target music does not need to be cached again when it is played again in the future, optionally, if there is cached data corresponding to the target music, the target music is added to the cache list.

[0066] The cached data may be data cached for the target music, may be all cached data for the target music, or may be partial cached data for the target music.

[0067] Specifically, if a cache operation is performed on the target music, and there is cached data corresponding to the target music, the target music can be added to the cache list, so that when the target music is played later, the cached data in the cache space can be called for playing. If the cached data is part of the cached data of the target music, the cached data can be played, and the subsequent cache can continue to be cached.

[0068] In order to clean up the cache space in time, optionally, if a preset cleaning condition is met, the music cache in the cache space is cleaned up.

[0069] Among them, the preset cleaning condition can be a pre-set condition for triggering cleaning, for example: the music cache in the cache space reaches a cleaning threshold, or the uncalled time length of the music cache in the cache space reaches an uncalled time length threshold, etc.

[0070] Specifically, when it is detected that the music cache in the cache space reaches a preset cleaning condition, the music cache in the cache space is cleaned according to a preset cleaning rule, for example, the music cache is cleaned according to the first-in-first-out principle, or the music cache whose unused time reaches an unused time threshold is cleaned.

[0071] The technical solution of the embodiment of the present invention is as follows: when a music playing instruction is received, it is determined whether the target music corresponding to the music playing instruction already exists in the cache list; if not, the target music is cached according to the preset initial cache ratio corresponding to the target music, and the cached target music is played; the target music is cached according to the current playing progress of the target music, the current cached ratio and the preset subsequent cache ratio, so as to cache in segments while playing; if a song switching instruction is received during the playing of the target music, the playing and caching of the target music is stopped, the music to be played is determined according to the play list, and the music to be played is played according to the cache list, so as to avoid caching all the target music when the user does not need the target music; if a song switching instruction is received during the playing of the target music, the playing and caching of the target music is stopped, the music to be played is determined according to the play list, and the music to be played is played according to the cache list, so as to pre-cache the music to be played in advance, improve the user experience, solve the problem of wasting storage space and traffic caused by caching the entire song every time the play is clicked, and failing to cache according to the user's listening situation, and achieve the technical effect of caching the target music while playing, saving traffic and cache space.

[0072] Embodiment 3

[0073] As an optional implementation scheme of the above embodiments, Figure 3This is a structural diagram of a music caching system provided by Embodiment 3 of the present invention, wherein the explanations of terms that are the same as or corresponding to the above embodiments are not repeated here.

[0074] The music cache system includes a cache management module and a play control module.

[0075] The cache management module is used to determine when to cache, set various cache parameters, and manage cache content. The playback control module is used to receive playback instructions, song switching instructions, etc., update the playlist, and play music.

[0076] The cache management module includes: a pre-cache management submodule, a cache configuration submodule, a cache judgment submodule, a cache execution and interruption submodule, and a cache list submodule.

[0077] Among them, the pre-cache management submodule is used to perform cache judgment and initial cache execution for the next music in the playlist. The cache configuration submodule is used to set or obtain the initial cache ratio (preset initial cache ratio), the global cache ratio (currently cached ratio), the progressive cache ratio (preset subsequent cache ratio), the pre-cached previous playback progress threshold (preset subsequent cache threshold), and the pre-cache initial cache ratio (preset initial cache ratio to be played). The cache judgment submodule is responsible for judging whether the cache is in progress and whether to terminate the decision. The cache execution and interruption submodule is responsible for executing cache actions and stopping actions. The cache list submodule is responsible for managing cache content, including song ID, cache progress, cache cleaning when the cache space is full, etc.

[0078] The play control module includes: a play control submodule, a play list submodule and a play output submodule.

[0079] The playback control submodule is responsible for triggering the playback, pause, song switching, etc. of the music. The playlist submodule is responsible for recording the playlist, updating the playlist, recording the next song (music to be played) of the current playback content in the playlist, the playback progress (current playback progress), and the pre-caching playback progress threshold of the next song (pre-set next song cache threshold). The playback output submodule is used to output the cached content to the player for sound output and content display output.

[0080] Figure 4 FIG. 1 is a flow chart of a music caching method provided by Embodiment 3 of the present invention. Figure 4 The method of this embodiment specifically includes the following steps:

[0081] 1. Click to play song A (target music), and the playback control submodule triggers cache judgment.

[0082] 2. Determine whether song A is in the cache list. If so, play it. If not, execute 3.

[0083] 3. Execute caching through the initial cache ratio preset in the cache configuration submodule, and play through the playback output submodule.

[0084] 4. Determine whether a song switching operation occurs. If so, stop caching song A and cache and play the next song according to the playlist. If not, execute 5.

[0085] 5. Execute caching through the progressive cache ratio in the cache configuration submodule. When the playback progress reaches the pre-cached previous playback progress threshold, cache and play the next song according to the playlist according to the pre-caching strategy.

[0086] 6. During the process of caching song A, determine whether the cache of song A is complete. If so, add song A to the cache list. If not, perform caching through the progressive cache ratio in the cache configuration submodule.

[0087] The technical solution of this embodiment progressively caches and plays songs through a music cache system, thereby solving the problem of waste of traffic and cache space caused by overall caching of songs under high network speed conditions, and achieving the technical effect of controlling the cache progress according to the user's playback progress and song switching operations to save cache space and traffic.
