[0055] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0056] The Linux system or Android system expands multiple USB interfaces through USB HUD (USB hub is a USB device used to expand USB interfaces); the CD drive is connected to the device through the USB interface, and then a CD audio management system is developed on the device side to manage the CD audio. The CD drive is selected in the management center, and then the information of the CD drive is obtained through the USB interface, which includes the audio configuration information and audio data of the audio track.

[0057] The network server is designed to manage audio and provide multimedia services to the outside world. Other network devices can access the multimedia resources of the multimedia server through NAS (Network Attached Storage, which is a device connected to the network and has data storage function, so it is also called "network storage"); they can also search for devices through UDP (User Datagram Protocol, which is a connectionless transport layer protocol that provides simple and unreliable transaction-oriented information transmission services) and TCP (Transmission Control Protocol, which is a transmission protocol specially designed to provide reliable end-to-end byte streams on unreliable Internet networks) to connect and obtain real-time audio stream data.

[0058] In the embodiment of the present application, a network multimedia server system based on a USB interface CD drive is proposed, which enables a network device to hang multiple CD drives, and the system manages multiple CD drives at the same time; at the same time, the system manages and captures the audio tracks of multiple drives (capturing the tracks means capturing audio from an audio CD in digital form, also called digital audio extraction (DAE), and then sharing the audio through multiple network protocols).

[0059] The CD audio management method and the CD audio management system are described below in conjunction with some specific embodiments.

[0060] See also Figure 1 An embodiment of the present application provides a CD audio management system, which is applied to a server. The system includes: a device management module 10, a data management module 20 and a multimedia management module 30.

[0061] The device management module 10 , the data management module 20 and the multimedia management module 30 are connected in sequence, and the device management module 10 is also used to connect to a plurality of CD devices 40 .

[0062] The device management module 10 is used to analyze the selected target CD device 4A after receiving the target selection instruction from the user, so as to obtain the audio data of the target CD device 4A.

[0063] The data management module 20 is used to encode the audio data to obtain first encoded data.

[0064] The multimedia management module 30 is used to use a broadcast tool to receive broadcast instructions of a target client device 50 to be connected within a preset range, and establish a first connection channel to connect to the target client device 50; and to use audio data to process the first encoded data and send the obtained second encoded data to the target client device 50.

[0065] In this embodiment, each of the CD devices is marked as 40, but for the sake of distinction, the first CD device is marked as 41, the second CD device is marked as 42, and so on until the nth CD device is marked as 4n.

[0066] Optionally, see also Figure 2 In this embodiment, a CD audio management system is designed on an existing multimedia server to form Figure 2 Network device multimedia server in.

[0067] The management system of CD audio includes: device management module 10, data management module 20 and multimedia management module 30 (or multimedia management center). The multimedia server is connected to several CD optical drives (devices) through interfaces such as USB. The audio data is a CD track, which is a PCM code stream (PCM stands for Pulse-Code Modulation, which is pulse modulation coding in Chinese. PCM code stream is a coding method in digital signal processing, known as lossless coding format); PCM is a digitization method for analog signals, and pulse code modulation is one of the coding methods for digital communication. The main process is to sample analog signals such as voice and images at regular intervals to discretize them, and at the same time round the sampled values ​​to the nearest integer according to the hierarchical unit, and at the same time represent the amplitude of the sampled pulse according to a set of binary codes.

[0068] Then, the implementation process of the CD audio management system is as follows:

[0069] First, after the user selects (at least one) target CD device 4A from the mounted CD devices 40, the device management module 10 will analyze the target CD device 4A according to the received target selection instruction, and obtain the audio data of the target CD device 4A, that is, realize the track capture process.

[0070] Then, the data management module 20 encodes the audio data to obtain first encoded data in a target encoding format.

[0071] Secondly, the multimedia management module 30 uses the broadcast tool to receive the broadcast instruction of the target client device 50 to be connected within the preset range, that is, to find the target client device 50 that can be found within the preset range, and establish a first connection channel to connect to the target client device 50.

[0072] Finally, the multimedia management module 30 processes the first coded data using the audio data to obtain second coded data, and sends the second coded data to the target client device 50 via a wireless network or Ethernet.

[0073] In another embodiment of the present application, the CD audio management system will manage and capture tracks of multiple target CD devices 4A simultaneously in multiple threads, and share the acquired audio data at the same time.

[0074] See also Figure 3 The present application embodiment provides a CD audio management method, which is applied to a server side, and the method includes:

[0075] S100. After receiving the target selection instruction from the user, analyze the selected target CD device 4A to obtain the audio data of the target CD device 4A.

[0076] Optionally, see also Figure 4 , the CD audio management method is applicable to the CD audio management system, then, the specific implementation process of the CD audio management method is as follows:

[0077] First, after the user selects at least one target CD device 4A, the device management module 10 (corresponding to Figure 4 The CD intelligent management module in the system will receive the user's target selection instruction and analyze the target CD device 4A according to the target selection instruction, that is, the target CD device 4A will capture the track and obtain the audio data of the target CD device 4A.

[0078] In the present application, the target CD device 4A is analyzed according to the target selection instruction to obtain audio data, so that efficient multi-device synchronous track grabbing can be achieved, thereby achieving simultaneous management of multiple CD optical drives.

[0079] Furthermore, in step S100, after receiving the target selection instruction from the user, the selected target CD device 4A is analyzed to obtain the audio data of the target CD device 4A, which also includes:

[0080] S000. After receiving the mode selection instruction from the user, identify several CD devices 40 connected to the server and record their numbers.

[0081] Optionally, before receiving the user's target selection instruction, the user first performs a mode selection to generate a mode selection instruction (corresponding to Figure 4 The device management module 10 will identify the CD devices 40 connected to the server according to the received mode selection instruction, that is, detect, enumerate and number the CD devices 40 (corresponding to Figure 4 Detecting CD devices 40 and enumerating CD devices 40), that is, detecting and identifying the type of the insertion event of the USB interface, and after identifying a number of CD devices 40 connected to the USB interface, enumerating and numbering the CD devices 40.

[0082] For further information, see Figure 5 Step S100: after receiving the target selection instruction from the user, the following steps are also included:

[0083] S1001, after selecting a target CD device 4A from a plurality of CD devices 40 according to a target selection instruction, configuring the rotation speed of the target CD device 4A to control the working mode of the target CD device 4A according to the user's mode selection instruction;

[0084] S1002: Obtain the track capture progress and the audio data playback progress of the target CD device 4A, and display the track capture progress and the playback progress.

[0085] The types of working modes include: a full-speed mode, a normal mode, a power-saving mode, and a combination of high-performance modes. Full-speed mode: read the audio data of the current track of the CD device 40, and keep the CD device 40 rotating at high speed until the CD play mode is exited; normal mode: read the audio data of the current track of the CD device 40, and keep the CD device 40 rotating at high speed until the current track is played; power-saving mode: after reading the complete audio data of the current track of the CD device 40, the CD device 40 will no longer rotate at high speed, and the SEEK (pointer movement) operation will not rotate the CD device 40; high-performance mode: after reading the complete audio data of all tracks of the CD device 40, the CD device 40 will no longer rotate at high speed, and the SEEK operation will not rotate the CD device 40.

[0086] Optionally, see also Figure 6 After receiving the target selection instruction from the user, the process of processing the track grabbing of the device management module 10 needs to be designed first:

[0087] First, multithreading is enabled, a call is made to open the CD device 40, a call is made to initialize the CD device 40, and a call is made to configure the CD to configure the rotation speed and working status of the C device.

[0088] Then, the working mode (full-speed mode, normal mode, power-saving mode and high-performance mode) of the target CD device 4A is controlled according to the user's mode selection instruction. Afterwards, if the working mode is switched or the sharing function is turned off, the CD (device) management is released and exited.

[0089] When the device management module 10 analyzes the target CD device 4A to obtain audio data, the device management module 10 will also obtain the track capture progress of the target CD device 4A, and after obtaining the playback progress of the audio data, update the progress bar in real time and display the track capture progress and playback progress.

[0090] For further information, please refer to Figure 3 , S200, encode the audio data to obtain first encoded data.

[0091] Optionally, see also Figure 7 and Figure 8 After analyzing the audio data, the data management module 20 (corresponding to Figure 4 The CD audio data intelligent module in the system first starts multi-threading, selects the encoding type, and encodes and saves the audio data, or directly saves the audio data to obtain the first encoded data, and saves it in the database, and then notifies the multimedia management center (i.e., the multimedia management module 30).

[0092] Among them, the encoding type can be selected, and the encoding types include: (1) lossless encoding: wav, aiff / aif; (2) lossless compression encoding: flac (an audio format used for lossless compression of digital audio files), ape (Mokey's audio, abbreviated as APE, is a digital music compression format), wv (WavPack, an open (BSD license) cross-platform audio compression and decompression algorithm), m4a (is the file extension of the MPEG-4 (a set of video and audio compression standards) audio standard, a digital audio format), Apple Lossless ((Apple Lossless Audio Codec, ALAC) is Apple's lossless audio compression encoding format); (3) lossy compression encoding: for example, mp3 (full name Moving Picture Experts Group Audio Layer Ⅲ, Chinese name Dynamic Image Experts Compression Standard Audio Layer 3), aac (Advanced Audio Coding, Chinese name Advanced Audio Decoding, is a lossy audio compression format defined by the MPEG-4 standard), wma (Windows Media Audio, is a lossy audio compression file format), jpeg (Joint Photographic Experts Group, whose Chinese name is Joint Photographic Experts Group, it is an image storage format, a standard for continuous tone static image compression), rmvb (a multimedia packaging format with dynamic bit rate extension), ogg (OGG Vobis, an open multimedia container format, commonly used to store audio and video files), wmv (Windows Media Video, a general term for a series of video codecs and related video encoding formats developed by Microsoft).

[0093] For further information, please refer to Figure 3 , S300, using a broadcast tool to receive a broadcast instruction of a target client device 50 to be connected within a preset range, and establish a first connection channel to connect to the target client device 50.

[0094] Optionally, in one embodiment of the present application, after encoding the audio data to obtain the first encoded data, the multimedia management module 30 in the management system of the CD audio starts a thread, and uses a broadcast tool, such as a UDP server, etc., to receive broadcast instructions of the target client device 50 to be connected within a preset range, so as to discover and connect to the target client device 50.

[0095] Then, a first connection channel, such as TCP, is established to connect with the target client device 50 .

[0096] Among them, UDP is a datagram-oriented protocol that does not provide connection stability and reliability, but focuses on quickly sending datagrams from one node to another; TCP is a communication protocol for wide area networks, and its purpose is to provide a communication method with the following characteristics between two communication endpoints when communicating across multiple networks.

[0097] In the present application, after using a broadcast tool to receive a broadcast instruction of a target client device 50 to be connected within a preset range, a first connection channel is established to connect with the target client device 50, thereby establishing a connection with the client device and preparing for data sharing.

[0098] For further information, see Fig. 9 Step S300, using a broadcast tool to receive a broadcast instruction of a target client device 50 to be connected within a preset range, and establishing a first connection channel to connect to the target client device 50, including:

[0099] S310, using a multicast domain name resolution protocol, using network broadcasting, or creating a UDP server and then using the UDP server to search for a target client device 50 within a preset range, and receiving a broadcast instruction of the target client device 50;

[0100] S320 , creating a TCP server to establish a first connection channel for connecting the server end and the target client device 50 .

[0101] Optionally, see also Fig.10 After encoding the audio data to obtain the first encoded data, the multimedia management module 30 starts a thread and enters the device discovery phase:

[0102] First, a UDP server is created and then waits for connection, and then the UDP server is created, or a multicast domain name resolution protocol or network broadcast is directly used to search for the target client device 50 within a preset range, and the broadcast instruction of the target client device 50 is received.

[0103] Among them, the heartbeat mechanism can be used to determine whether the target client device 50 is online to determine whether it can be connected; the heartbeat mechanism is a commonly used way for the client to maintain a connection with the server. By regularly sending a heartbeat signal (also known as a heartbeat packet), the client and the server can confirm with each other whether the other party is still online and connected. If no heartbeat response is received for a long time, it can be determined that the connection is disconnected and the reconnection logic is triggered.

[0104] Among them, the heartbeat packet is a self-defined command word that periodically notifies the client and the server of their own status. It is sent at a certain time interval, similar to a heartbeat, so it is called a heartbeat packet.

[0105] Then, enter the device connection stage:

[0106] A TCP server is created to establish a first connection channel for connecting the server end and the target client device 50, and wait for connection. Similarly, a heartbeat packet can be used to determine whether the connection is successful.

[0107] Furthermore, after obtaining the first coded data, the method further includes:

[0108] S10 , establishing a second connection channel to connect to the target client device 50 , and sending the first encoded data to the target client device 50 .

[0109] The second connection channel includes: a network storage server. A network storage server is a NAS server. NAS: Network Attached Storage, which is called network attached storage in Chinese. It is literally a device connected to the network with data storage function, so it is also called "network storage". It is a dedicated data storage server. It is data-centric, completely separates storage devices from servers, and centrally manages data, thereby releasing bandwidth, improving performance, reducing total cost of ownership, and protecting investment.

[0110] Optionally, in another embodiment of the present application, after the audio data is encoded to obtain the first encoded data, a second connection channel can be directly established, such as a NAS server, and the second connection channel is used to connect to the target client device 50. Then, the first encoded data is directly sent to the target client device 50 to achieve data sharing.

[0111] For further information, please refer to Figure 3 , S400, after processing the first encoded data using the audio data, the obtained second encoded data is sent to the target client device 50.

[0112] Optionally, after obtaining the first coded data, the data management module 20 continues to process the first coded data according to the audio data, mainly performing network coding, to obtain second coded data. Network coding is an information exchange technology that combines routing and coding. Its core idea is to perform linear or nonlinear processing on the information received on each channel at each node in the network, and then forward it to the downstream node. The intermediate node plays the role of an encoder or a signal processor.

[0113] Then, the second encoded data is sent to the target client device 50 by using a network communication protocol (eg, wireless network, Ethernet, etc.).

[0114] In this application, efficient and fast CD audio sharing is achieved through multiple network protocols.

[0115] For further information, see Fig.11 Step S400, after processing the first coded data using the audio data, the obtained second coded data is sent to the target client device 50, including:

[0116] S410, encapsulating the protocol header, the network frame sequence number, the data frame size and the audio data into the first coded data to obtain third coded data;

[0117] S420 , verify each frame of the third encoded data, and use the TCP server to send the verified third encoded data to the target client device 50 .

[0118] Optionally, see also Fig.12 , the specific process of processing the first coded data is as follows:

[0119] The protocol header, the network frame sequence number, the data frame size and the audio data are sequentially encapsulated into the first coded data to obtain the third coded data.

[0120] Then, each frame of the third encoded data is verified, for example, a CRC check is performed, and the third encoded data that passes the check is sent to complete the sharing of the CD track data.

[0121] Among them, the protocol header (is the part of the HTTP protocol used to transmit additional information about the request, and the protocol header is the part of the HTTP protocol used to transmit additional information about the request, which contains the metadata required for communication between the client and the server. CRC (Cyclic Redundancy Check), that is, cyclic redundancy check, is a fast algorithm that generates a short fixed-bit check code based on data such as network data packets or computer files. It is mainly used to detect or check errors that may occur after data transmission or storage.

[0122] Furthermore, each frame of the third coded data is verified, and then the following steps are further included:

[0123] S4201: If the third coded data of the current frame fails the inspection, the third coded data of the current frame is re-acquired and re-encapsulated.

[0124] Optionally, when the third coded data is verified, if the third coded data of the current frame fails the verification, it is necessary to re-acquire the third coded data of the current frame and re-encapsulate it.

[0125] It can be understood that the device of this embodiment corresponds to the CD audio management method of the above embodiment, and the optional items in the above embodiment are also applicable to this embodiment, so they will not be repeated here.

[0126] The present application also provides a terminal device.
