What Practical Value Does Full-Digital Uncompressed Transmission in Video Optical Terminals Bring to Surveillance Images?

Full-digital uncompressed video transmission refers to video signals being sent directly onto the fiber in digital form, without compression encoding in between, so the receiving end restores the original image data. Its direct value lies in three aspects: first, there is no detail loss caused by compression, and both static and dynamic high-resolution images are fully preserved; second, the encoding and decoding stages are eliminated, so the link introduces no additional latency, making it suitable for latency-sensitive applications such as video conferencing and distance learning; third, it inherently avoids the intermodulation interference issues of analog FM and PM optical terminals. The IDM-VNT2204 multi-service video optical terminal also features automatic gain control and lightning-protection self-recovering fuse circuit design, supports lossless video regeneration and relay, and is compatible with NTSC, PAL, and SECAM video standards.
