[0045] In order to more clearly illustrate the embodiments of the present invention or the technical solutions of the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0046] Figure 1 A flowchart of a store music playing method provided by an embodiment of the present invention;

[0047] Figure 2 This is a structural block diagram of a store music playback device provided by an embodiment of the present invention;

[0048] Figure 3 This is a structural block diagram of a store music playback system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0049] The core of this invention is to provide a method for playing music in stores. In the prior art, store playback primarily relies on server-side decoding, browser plugins downloading audio material, and then execution by the playback device. Existing store music playback devices can only play audio material, with the browser plugin handling both playback tasks and downloading audio material. This undoubtedly increases store operating and management costs and reduces operational efficiency.

[0050] The present invention provides a store music playback method, which includes registering a virtual device on a server side by a playback device; sending a playback task to the playback device side through the server side; the playback device side receives the playback task, downloads the audio material in the playback task and adds it to a playback queue; and the playback device side plays the audio material based on the playback queue.

[0051] The method of the present invention develops a set of embedded music playback software on the playback device end, and then sends the audio and music playback rules of the cloud server to the playback device end through a real-time communication protocol. When the device on the playback device end receives the communication, it starts to download the audio material and parses and plays it according to certain rules, thereby realizing the integration of the audio playback capability of the playback device end and achieving the goal of integrating the video storage capability and music playback capability of the playback device end itself.

[0052] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] Before the detailed description, the present invention explains the relevant terms:

[0054] Playback task: A playback task is to send multiple audio files and specify the play date, time period, etc. The sent audio files are played in rotation within the specified play date and time period.

[0055] Backend: A service is deployed on the server side, and the store equipment involved will communicate with the backend through websocket and http.

[0056] Scheduled: When a task is issued, it may not be triggered immediately. You need to wait for the scheduled date and time period to trigger the playback.

[0057] Insert: When a normal task is playing, a higher priority task is inserted. Generally, the task will only be played once. The software will stop the current playback and play the current inserted task first. After the inserted task is finished, the normal task before it is played.

[0058] Delete: After the playback task is issued, the background can delete the task, and the task issued to the store device will stop playing and be deleted.

[0059] Please refer to Figure 1 , Figure 1 This is a flowchart of the store music playing method provided by an embodiment of the present invention.

[0060] See also Figure 1 In an embodiment of the present invention, the store music playing method includes:

[0061] S1: The playback device registers a virtual device on the server.

[0062] Furthermore, registering a virtual device specifically involves the server recording the store information and physical information of the playback device, and generating a unique identifier corresponding to the playback device based on the MAC address reported by the playback device. The above process is called device registration. Device registration is the process of recording the store and physical information of the device when the device is first activated. In this embodiment, the playback device can be multiple playback devices, and each store can have one or more playback devices. Each playback device needs to report a MAC address to generate a corresponding unique identifier. The playback device in this embodiment is an NVR (Network Video Recorder, which is the storage and forwarding function of a network video surveillance system), and the music playback software is integrated into the ARM processor of the NVR device.

[0063] It should be noted that when the NVR device is first registered, it sends the device's MAC address to the server. The server will use the MAC address it reports as a unique identifier to generate a virtual music player. Users can use this virtual music player to distribute and manage audio files.

[0064] S2: Send the playback task to the playback device through the server.

[0065] Furthermore, the web client sends instructions for managing playback tasks to the playback device through the server. These instructions include at least adding, deleting, inserting, and pausing. Specifically, when a user adds or deletes a playback task through the web client, the web client sends a request to the server via HTTP. After receiving the task, the server connects to the store's music playback software through a real-time communication protocol (WEBSocket) and sends the corresponding task to the playback software.

[0066] The playback device includes a real-time communication protocol, and the functions of the real-time communication protocol include at least one of the following:

[0067] Connect to the server;

[0068] Receive instructions and manage playback tasks according to the instructions;

[0069] Feedback the current playback status and content to the server.

[0070] In this embodiment, the playback task includes audio material and playback rules. The playback rule is specifically: a preset playback time period, during which a preset playback device is allowed to play the audio material cyclically or sequentially at a preset frequency.

[0071] It should be noted that the server can determine the health of the playback device based on the current playback status and playback content fed back by the playback device. Specifically, the current playback status includes at least starting playback, playing, paused, playback failure, and playback completed. The playback content includes at least the name and ID of the audio material and the playback progress of the audio material. Users can query and manage the playback of store devices through communication between the web and the server.

[0072] Specifically, the server feedback on the current playback status and playback content includes:

[0073] 1) Callback to the backend when the audio material being played changes. The callback is when the store device notifies the backend of the status and progress of the audio material being played via websocket communication. The status is the playback state, i.e., started, playing, failed, ended, etc.

[0074] 2) When playing audio material, the audio material is parsed to obtain the playing time and current playing progress. The callback is to call back the audio material id being played, the total length of the audio material and the current playing time to the background when the audio material is playing.

[0075] It should be noted that audio materials have fixed parameters such as audio format, sampling rate, and channels. The music playback software in this embodiment will analyze the audio material to obtain the total playback time of the audio material, and will calculate the current playback time during audio playback. The current playback time / total duration is the progress of the audio material.

[0076] S3: The playback device receives the playback task, downloads the audio material in the playback task and adds it to the playback queue.

[0077] Specifically, the playback device further includes a task control module, which is used to download music materials and generate a playback queue. The process is as follows:

[0078] Receive playback tasks;

[0079] Determine whether the audio material is downloaded, and if not, add the audio material to the download queue;

[0080] Based on the playing rules described in S2, the downloaded audio material is set to be played at a scheduled time to generate a playing queue.

[0081] S4: The playback device plays the audio material based on the playback queue.

[0082] Furthermore, the playback device also includes a playback thread, which is used to play audio materials. The process is as follows:

[0083] Receive playback queue;

[0084] Determine the format of the audio material and parse the audio material. Specifically, in this embodiment, for example, wav format files are parsed using miniAudio, while mp3 format files are decoded using miniMp3. For audio materials in other formats, this embodiment can also use corresponding decoding methods.

[0085] Select the NVR device to play the audio material.

[0086] The embodiment of the present invention provides a method for playing music in a store. By developing embedded music playing software in the playing device, a virtual device is registered on the server and bound to the playing device. Tasks can be issued individually according to the store, and audio files can be downloaded automatically. The method of this embodiment uses a real-time communication protocol to achieve three-party communication between the WEB end, the server end, and the client end to control the music playing process in real time, and remotely handle abnormal playback. Timed polling provides timed playback of ordinary tasks and temporary insert playback tasks, etc., thereby improving the efficiency of store music playing management. By applying the method disclosed in the embodiment of the present invention, the music playing capability is successfully integrated into the NVR device, and the original one monitoring device and one music playing device are compressed into the same device, which greatly reduces the company's procurement cost, management cost, and maintenance cost.
