Abstract

The invention relates to a long-distance transfer system for video data, which comprises a transmitting terminal, an optical fiber and a receiving terminal, wherein the transmitting terminal is connected with the receiving terminal through the optical fiber; the transmitting terminal converts received video data into video optical fiber signals, transmits the video optical fiber signals to the receiving terminal through the optical fiber, simultaneously converts control optical signals transmitted from the receiving terminal into control signals and outputs the control signals to a camera control terminal; and the receiving terminal converts the video optical fiber signals transmitted through the optical fiber into video data and provides the video data to an external system, simultaneously receives the control signals input by the camera control terminal and converts the control signals into the control optical signals, and then transmits the control optical signals to the transmitting terminal through the optical fiber. The invention realizes non-loss real-time transmission of the video observation data of a telescope, has universality, and is especially suitable for the occasion of long-distance transmission of a Camera link video.

Description

technical field [0001] The invention relates to a video data long-distance transmission system. technical background [0002] The transfer rate of Camera link protocol can reach 2.83Gb / s. It is sufficient to meet the requirements of today's digital cameras for large data transmission rates. It has been more and more widely used in high-resolution digital cameras such as aviation, aerospace, and astronomical observations. It is often used in high-precision telescope observations, but the Camera link protocol transmission The short distance is not suitable for the requirements of long-distance transmission of telescope observation data. Telescope observation data cannot be obtained in real time by using data storage technology. Invention content: [0003] The technical problem to be solved by the present invention is to provide a video data long-distance transmission system capable of realizing lossless real-time long-distance transmission of video observation data. [00...
