Embodiment 1
[0026] See figure 1 , embodiment one includes:
[0027] 101. The first device collects data.
[0028] The first device collects data, and the first device is capable of collecting data. For example, the first device may include a camera, a microphone, and the like. The data collected by the first device may include audio data and video data, but is not limited thereto.
[0029] 102. The first device splits the data into at least two data blocks according to the encoding manner of the data, and prioritizes the at least two data blocks.
[0030] The first device splits the collected data into at least two data blocks, and the first device splits the data according to a coding method of the data. After the data is split, it can be sorted according to the priority of the data blocks. For example, if the data is video data, the data may be split into basic data blocks, extended data blocks, audio data blocks, etc. according to the encoding method of the video data. The priority ...
Embodiment 2
[0042] Embodiment 2 provides another data transmission method. In this method, the first device can send a test data packet to the second device before collecting data, and the second device can determine the data fluency according to the test data packet. , the first device may determine to establish at least two TCP transmission channels according to the data fluency. Such as figure 2 Shown, embodiment two comprises:
[0043] 201. The first device sends a test data packet to the second device.
[0044] The first device sends a test data packet to the second device, and the first device may send the test data packet to the second device through a pre-established TCP transmission channel. The second device receives the test data packet sent by the first device.
[0045] A control channel may be established between the first device and the second device.
[0046] 202. The second device determines the data fluency according to the test data packet.
[0047] The second devi...

Abstract
The invention discloses a data transmission method and related equipment. The method comprises the following steps that first equipment acquires data; the first device splits the data into at least two data blocks and prioritizes the at least two data blocks; and the first device sends the at least two data blocks to the second device through the at least two TCP transmission channels. The secondequipment receives a data block from the first equipment through at least two TCP transmission channels, the data block comprises a first data block, and the first data block is transmitted through the TCP transmission channel with the highest priority in the at least two TCP transmission channels; and the second device processes the data block, wherein the processing comprises analyzing the datablock or transmitting the data block. The first device can perform priority ranking on the data blocks, it is ensured that the first data block with the highest priority is transmitted through the TCPtransmission channel with the highest priority, and even if network congestion occurs, it can be ensured that the first data block with the high priority can be received by the second device.
Description
technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and related equipment. Background technique [0002] Most of the current acquisition devices and playback devices are connected by universal serial bus (universal serial bus, USB). On the basis of the USB1.1 or USB2.0 protocol, the protocol standard (USB videoclass, UVC) defined by the USB video capture device is adopted. transfer data. [0003] The UVC protocol is adopted between the acquisition device and the playback device, and video data or audio data is transmitted through a UVC link. When the network is congested or the playback device freezes, the playback device may not be able to receive data, resulting in the inability to play the video or audio. Contents of the invention [0004] The first aspect of the embodiment of the present invention provides a data transmission method, which may include: the first device collects data; the first d...
