The invention provides a network camera and a data transmission method thereof. The network camera comprises an image sensing unit, a digital image processing unit, a serial data encoding unit and a network control unit, wherein the image sensing unit is used for searching image information; the digital image processing unit is used for converting and compressing the image information to form a digital image information; the serial data encoding unit is used for encoding the digital image signal so as to generate a data signal according with a software interface of an operating system; and the network control unit is used for converting the data signal into a serial network signal packet. Therefore, a user can connect the network camera and a computer or other embedded system devices with network interfaces through a network bridge connector; compared with the conventional network camera restrained by the length of a universal serial bus (USB) connection wire, the network camera has the advantages that: the distance between the network camera and the computer can be increased greatly, and the convenience and the diversity of the use are improved.
Description
Technical field [0001] The present invention relates to a network camera and a data transmission method thereof, in particular to a network camera and a data transmission method thereof having a network interface to transmit video and audio signals. Background technique [0002] The webcam (WebCam) digitizes the signal from the image sensor to generate a video stream, and transmits the video stream to the computer through a USB data transmission line. The user can only watch the image retrieved by the webcam through the computer connected to the camera , And then send the camera image to another specific computer device via the network application in the computer. [0003] The above-mentioned external network camera is connected to the computer through a USB transmission line, and some high-end notebook computers adopt a built-in method to install the network camera inside the computer. However, whether it is a built-in or an external network camera, they all face the same problem...
