Description

BYOD method and device Technical Field

[0001] The present invention relates to the field of data communications, and in particular to a BYOD method and device. Background Art

[0002] Currently, in the BYOD (Bring Your Own Device) method, the BYOD device receives audio and video data streams from the VCS (Video Conference System) host via the network. It then uses the BYOD program to send the video to the UVC (USB Video Class) device via the BULK (bulk transfer mode) endpoint and the audio to the UAC (USB Audio Class) device via the ISOC (isochronous transfer mode) endpoint. The PC receives the video data from the UVC device enumerated by the BULK endpoint and plays it on the video software on the PC. The PC receives the audio data from the UAC device enumerated by the ISOC endpoint and plays it on the audio software on the PC. This allows the PC to play the audio and video data from the VCS (Video Conference System) host, thus implementing the BYOD function.

[0003] Although the existing solution implements BYOD function, it requires the use of actual USB endpoint devices for enumeration during use. In the multi-stream scenario, the requirement for the number of USB endpoints is very high, and there is a risk that the number of hardware endpoints cannot be met.

[0004] Summary of the Invention

[0005] The present invention provides a BYOD method and device to solve the technical problems of the existing solution of enumerating UAC / UVC devices through actual USB endpoints, resulting in a limited number of devices and high hardware requirements.

[0006] In order to solve the above technical problems, the present invention provides a BYOD method, comprising:

[0007] Acquiring network data, wherein the network data includes multiple channels of audio data and multiple channels of video data;

[0008] The network data is sent to the PC end through a BULK endpoint according to the network protocol, so that the PC end writes the multi-channel audio data into each virtual UAC device and writes the multi-channel video data into each virtual UVC device.

[0009] The present invention uses a BULK endpoint to package network data and send it to the PC through the network protocol, and creates a virtual UAC device and a virtual UVC device based on the network protocol, avoiding the enumeration of UAC devices and UVC devices through actual USB endpoints, breaking hardware limitations, and having strong scalability. In addition, when transmitting data to the PC, there is no need to shunt audio data and video data, which simplifies the data transmission process and improves data transmission efficiency.

[0015] Furthermore, the obtaining of network data is specifically as follows:

[0016] Receive network data through a wired network card or a wireless network card.

[0017] In the present invention, network data is received through a wired network card or a wireless network card, and the network data is transmitted to the PC end through a network protocol. The data transmission formats of the two times are the same. Therefore, when the network data is received, there is no need to shunt the audio data and video data in the network data. They can be merged into one BULK port for transmission, which simplifies the data transmission process and improves data transmission efficiency.

[0018] Furthermore, after writing the audio data and video data into the virtual UAC devices and virtual UVC devices respectively, the method further includes:

[0019] Open all virtual UAC devices and virtual UVC devices through the audio software and video software on the PC respectively;

[0020] The audio data and the video data in all the virtual UAC devices and the virtual UVC devices are played simultaneously.

[0021] In a second aspect, the present invention further provides a BYOD device, comprising: a data acquisition module and a data forwarding module;

[0022] The data acquisition module is used to acquire network data, wherein the acquired network data includes multiple channels of audio data and multiple channels of video data;

[0023] The data forwarding module is used to send the network data to the PC end through a BULK endpoint according to the network protocol, so that the PC end writes multiple audio data into each virtual UAC device and writes multiple video data into each virtual UVC device.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] Example 1

[0040] Please refer to FIG. 1 , which is a flow chart of a BYOD method provided by an embodiment of the present invention, including steps 101 to 102, which are specifically as follows:

[0041] Step 101: Acquire network data, where the network data includes multiple channels of audio data and multiple channels of video data;

[0042] In this embodiment, the acquisition of network data is specifically as follows:

[0043] Receive network data through a wired network card or a wireless network card.

[0044] In this embodiment, the BYOD device obtains the network data sent by the VCS host through a wired network card or a wireless network card.

[0045] In this embodiment, the VCS host collects the video data and audio data, encodes and packages the video data using a video codec such as H.264 and an audio codec such as AAC, and sends the data to the BYOD device via the network.

[0046] In this embodiment, network data is received through a wired network card or a wireless network card, and the network data is transmitted to the PC through a network protocol. The data transmission formats of the two times are the same. Therefore, when the network data is received, there is no need to shunt the audio data and video data in the network data. They can be merged into one BULK port for transmission, which simplifies the data transmission process and improves data transmission efficiency.

[0047] Step 102: The network data is sent to the PC end through a BULK endpoint according to the network protocol, so that the PC end writes the multi-channel audio data into each virtual UAC device and writes the multi-channel video data into each virtual UVC device.

[0048] In this embodiment, the network protocol includes but is not limited to TCP / IP protocol, IPX / SPX protocol, and NetBEUI protocol.

[0049] In this embodiment, the TCP / IP protocol is used as an example for illustration. Since the TCP / IP protocol is a reliable transmission protocol with a retransmission mechanism, when transmitting audio data and video data, the reliability of the protocol itself can be relied upon to improve the anti-packet loss capability of data transmission, thereby improving the fault tolerance of the BYOD method and thereby enhancing the user experience.

[0050] In this embodiment, since the format of the audio data transmitted by the TCP / IP network protocol on the BYOD device and the PC is the same, when the network data is transmitted to the BYOD device, the BYOD device only needs to forward it. There is no need for the BYOD device to decode the network data and separate the audio and video streams for transmission through two ports. It can be transmitted through one port BULK.

[0051] In this embodiment, the PC is configured to write multiple channels of audio data into each virtual UAC device and multiple channels of video data into each virtual UVC device, specifically:

[0052] Parsing the network data to obtain the number of audio data and the number of video data;

[0053] Based on the network protocol, a corresponding number of virtual UAC devices are created according to the number of audio data, and a corresponding number of virtual UVC devices are created according to the number of video data;

[0054] The audio data and the video data are written into the virtual UAC devices and the virtual UVC devices respectively.

[0055] In this embodiment, the BYOD device forwards the network data to the PC via a BULK endpoint using the TCP / IP protocol. The PC receives the network data via the TCP / IP protocol and decodes the network data to obtain the number of audio data and the number of video data. Based on the TCP / IP protocol, a virtual UAC (USB audio class) device and a virtual UVC (USB video class) device corresponding to the number of audio data and the number of video data are created.

[0056] In this embodiment, the BOYD device sends data based on the TCP / IP network protocol. The network data is also transmitted via the USB interface using the USB over IP technology, that is, the USB interface supports data transmission using the TCP / IP network protocol.

[0057] In this embodiment, by creating virtual UAC devices and UVC devices corresponding to the number of video data and audio data based on the TCP / IP network protocol, there is no need to enumerate UAC devices and UVC devices through actual USB endpoints, which breaks the hardware limitations and improves scalability.

[0058] Please refer to FIG. 2 , which is a schematic diagram of data transmission in a BYOD method according to an embodiment of the present invention.

[0059] In this embodiment, a TCP / IP protocol stack, specifically LWIP (Lightweight IP), is built into the PC and BYOD device. This stack can run with or without operating system support. LWIP maintains the core functionality of the TCP protocol while reducing RAM (Random Access Memory) usage. It requires only a dozen KB of RAM and approximately 40KB of ROM (Read-Only Memory), making it suitable for use in low-end embedded systems.

[0060] In this embodiment, the BYOD device receives multi-channel audio and video data from the VCS host through a wired or wireless network card, and then transmits the audio and video data to the PC through the BYOD program via the TCP / IP network protocol. The BYOD program is software built into the BYOD device that receives and transmits the received audio and video data.

[0061] In this embodiment, each audio data is written to each virtual UAC device in a one-to-one manner through the TCP / IP protocol, and each video data is written to each virtual UVC device in a one-to-one manner.

[0062] In this embodiment, after writing the audio data and video data into the virtual UAC devices and virtual UVC devices respectively, the method further includes:

[0063] Open all virtual UAC devices and virtual UVC devices through the audio software and video software on the PC respectively;

[0064] The audio data and the video data in all the virtual UAC devices and the virtual UVC devices are played simultaneously.

[0065] In this embodiment, the audio software on the PC will open a virtual UAC device to play the received audio data. The video software on the PC will open a virtual UVC device to play the received video data, thereby enabling a multi-person audio and video call through simultaneous playback.

[0066] In this embodiment, the present invention uses a BULK endpoint to package network data and send it to the PC through the TCP / IP network protocol, and creates a virtual UAC device and a virtual UVC device based on the TCP / IP network protocol, avoiding the enumeration of UAC devices and UVC devices through actual USB endpoints, breaking hardware limitations, and having strong scalability; in addition, when transmitting data to the PC, there is no need to divert audio data and video data, which simplifies the data transmission process and improves data transmission efficiency.

[0070] In this embodiment, the data forwarding module 302 is specifically configured to:

[0071] Parsing the network data to obtain the number of audio data and the number of video data;

[0072] Based on the network protocol, a corresponding number of virtual UAC devices are created according to the number of audio data, and a corresponding number of virtual UVC devices are created according to the number of video data;

[0073] The audio data and the video data are written into the virtual UAC devices and the virtual UVC devices respectively.

[0080] An embodiment of the present invention also provides a computer device, comprising: a processor, a communication interface, and a memory, wherein the processor, the communication interface, and the memory are interconnected, wherein the memory stores executable program code, and the processor is used to call the executable program code to execute the BYOD method.
