This application belongs to the field of video processing technology, specifically disclosing a video encoding device and apparatus. Through this application, by employing an interface unit that includes a first interface supporting HDMI optical signal input and a backup interface for outputting electrical signals, the input / output compatibility and application flexibility of the device are broadened. The input optical signal is converted into an electrical signal by a light-to-electricity conversion unit, and the single electrical signal is synchronously distributed by a distribution unit. One path is losslessly looped out to the backup interface for local real-time display or recording, while the other path is sent to the video processing unit for encoding into a network video stream, enabling remote playback or storage of video content over a network. This solution seamlessly realizes the three core functions of acquisition, loop-out distribution, and encoding within a single device, solving the key problem of existing devices having limited functionality and being unable to simultaneously meet the combined needs of video storage, loop-out, and remote playback, significantly improving the overall applicability of the device in diverse application scenarios.
