Abstract

The invention provides a code stream transmission method and a camera based on USB. The code stream transmission method comprises the following steps: obtaining a target image to be processed and an image processing control command, compressing and packaging the target image into at least two code streams according to the image processing control command, wherein each code stream is compressed and packaged according to a resolution and a compression standard; transmitting the at least two streams to the opposite end device through at least two drive devices, wherein the drive devices and the code streams have one-to-one correspondence. The code stream transmission method and the camera based on USB provided by the invention can avoid the problems that the video quality of the remote transmission is not clear enough, and the video screen is not smooth enough because the video decoding time is too long, therefore, the user experience is improved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a code stream transmission method and a USB-based video camera. Background technique [0002] With the development of technology, cameras, especially cameras based on Universal Serial Bus (USB for short), are more and more widely used, many of which are used in surveillance and security. Bit stream refers to the data flow used by video files per unit time, also called bit rate, which is the most important part of picture quality control in video encoding. The resolution of the bit stream determines the clarity of the image encoded by the camera video. [0003] A USB-based camera encodes video by transmitting a code stream with a certain resolution, and transmits the encoded video. At present, USB-based cameras can only transmit one resolution stream at a time. However, in practical applications, some of the videos of USB-based cameras need to be transmitted remotely, and so...
