Embodiment Construction

[0033] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

[0034] The flowchart of the embodiment of the present invention is as figure 1 Shown.

[0035] The transmission method in this embodiment involves a video camera recorder, a USB video transmission module, and a video receiver. The video camera terminal is equipped with a video capture module, and also has a USB interface to connect with the USB video transmission module. The USB video transmission module includes a USB host controller that is electrically connected to the USB device controller in the video capture module, a USB device driver module that is started by the USB host controller, and a USB device driver module that receives video stream data sent by the video capture module. USB data receiving module. The USB host controller is responsible for re...

Abstract

The invention relates to a transmission method of a digital video stream. The method comprises the following steps: power on and initialization; the USB video transmission module waits for the HTTP command from the video receiving end through the network interface arranged on the USB video transmission module; after receiving the HTTP command, the USB video transmission module and the video recording terminal Carry out the handshake process; the USB video transmission module receives the real-time video stream data from the video recording end, if the video stream data is valid, then enter the next step, if the video stream data is invalid, return to the handshake process again; USB video transmission module Send real-time video stream data to the video receiver through the network interface. The present invention gets rid of the relatively complex structure of the usual UVC equipment, utilizes the simple and general structure type of USB transmission, is more conducive to the realization of the video equipment end and the transplantation of related drivers, is easy to understand and expand, simplifies the structure of the video transmission equipment, and reduces the transmission cost .

Description

Technical field [0001] The present invention relates to the field of video transmission, in particular to a transmission method of digital video stream. Background technique [0002] With the development of science and technology, the coding capabilities of current digital cameras, camcorders and other video capture and acquisition devices are getting stronger and stronger, and the related video resources are also increasing, causing the network load to become greater and greater. Video equipment is required as much as possible Capture and output video at high speed and high quality. At present, the commonly used UVC (USB Video Class) structure of the device is more complex, not easy to drive and implement, requires high device performance, and the entire transmission cost is relatively high, which is not conducive to technology promotion and application. Summary of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide...
