The 3G-SDI optical transceiver is suitable for the high-definition, reliable and high-definition performance standards of the TV industry. Hangzhou Feichang's 3G-SDI optical transceiver adopts the latest technology, adopts the H.264 encoding method, and adopts the dedicated VIDIO SFP optical module for high-definition SDI. Generally, it uses the SDI interface . Its products were first developed and used by customers in the radio and television industry, used in TV studios, Universiade live broadcasts, and later extended to the 1080P high-definition monitoring field, with reverse control data; the rate is 1.485G (also known as 1.5G, corresponding to the SMPTE-292M standard , Support 720P) and 2.97G (also known as 3G, corresponding to SMPTE-424M standard, support FULL HD full HD 1080P), to ensure that there is no flickering or black screen during the transmission of high-definition images. Next, we will introduce the difference between HD-SDI monitoring system and IP high-definition monitoring system in detail, let's take a look!
The difference between HD-SDI monitoring system and IP high-definition monitoring system:
1. Stability: HD-SDI monitoring system has no compression, no delay, and no smear when transmitted through HD-SDI optical transceiver; IP high-definition monitoring system will appear in transmission Frame loss, frame skipping, etc., and network congestion in IP transmission, there will be gaps in this period of time during storage, which is not conducive to follow-up tracking and inquiries.
2. Image effect: HD-SDI optical transceiver reaches 1.485G/s during transmission, while IP HD monitoring system is compressed during transmission and can only reach 10M/s, which can also be seen from the analysis of image code stream The HD-SDI surveillance system has clearer images, and the same HD surveillance images, SDI HD images are smaller than IP HD image streams, and HD-SDI images with the same stream are clearer than IP.
3. Versatility: HD-SDI monitoring systems are all SDI interfaces, and SDI equipment of various manufacturers can be compatible; and IP HD monitoring systems support ONVIF protocol, but basically all have their own changes, so even if the standard NVRs and IPCs that support the ONVIF protocol may not be able to communicate normally.
4. Security: The HD-SDI monitoring system builds a network through optical fiber transmission and is protected from external network intrusion; the IP high-definition monitoring system is transmitted and accessed through the external network, which is susceptible to artificial intrusion and has low security.
5. Convenience of installation and maintenance: The HD-SDI monitoring system only needs to replace the corresponding equipment on the analog line used; the IP HD monitoring system needs to be re-wired. ; The SDI monitoring system is easy to install and maintain, and the IP high-definition monitoring system requires specialized technical personnel for debugging and maintenance, which requires higher maintenance operators.
Well, the above content is the detailed introduction of Hangzhou Feichang on the difference between HD-SDI monitoring system and IP high-definition monitoring system, I hope it can be helpful to you!
