Sony FCB camera block
In the globalized business environment, cross-border video conferences have become an essential need for the daily operations of enterprises. However, in the face of different network environments and quality requirements, how to choose the most suitable video transmission solution? Today, we will delve deeply into the two major technical solutions of the 3G-SDI interface board and the VRS-UD350 LVDS/MIPI to IP network interface board, to help you make wiser choices in cross-border video conferences.
The 3G-SDI interface board and the VRS-UD350 LVDS/MIPI to IP network interface board are both independently developed by Xuanzhan Technology for SONY FCB high-definition camera modules and can also be used for other camera modules that follow SONY’s VISCA protocol.
1. 3G-SDI: The Professional Choice for Lossless picture quality
3G-SDI (Third Generation Serial Digital Interface) is a professional-level video transmission protocol. It transmits uncompressed high-definition video signals through coaxial cables or optical fibers, with a maximum transmission rate of up to 2.97Gbps, and can perfectly support 1080P/60fps high-definition video streams.
Core advantages
• Ultimate picture quality: As no compression is required, there is zero loss during video signal transmission, maintaining every detail of the original picture quality. It is particularly suitable for scenarios with strict requirements for image quality, such as medical imaging, engineering design, and remote training.
• Near-zero latency: Uncompressed transmission means there is no need for an encoding and decoding process, resulting in extremely low video latency and ensuring the real-time and natural smoothness of conversations in cross-border meetings.
• High reliability: Specifically designed for broadcasting and professional applications, it features strong anti-interference ability, stable signals, and is suitable for long-term uninterrupted operation.
However, 3G-SDI faces challenges in cross-border transmission: long-distance transmission relies on dedicated optical fiber lines, the rental cost of cross-border dedicated lines is relatively high, and the point-to-point transmission mode is not flexible enough when connecting multiple overseas nodes.
Ii. Network Control Board: A flexible and efficient networked solution
The VRS-UD350 LVDS/MIPI to IP Network interface board is a device that converts camera video signals into network video signals. It supports efficient H.265/H.264 compression coding and can transmit video signals over the Internet, enabling remote access and multi-point connection.
Core advantages
• Strong network adaptability: Specifically designed for complex network environments, it can automatically adapt to different network bandwidths and qualities, ensuring smooth video performance.
• Cross-regional flexible networking: Based on IP networks, the VRS-UD350 LVDS/MIPI to IP network interface board can easily achieve multi-point interconnection. Branches in different countries can quickly access the same conference system without the need to lay dedicated lines.
• High cost-effectiveness: Utilizing the existing Internet infrastructure for transmission, it significantly reduces the cost of cross-border dedicated lines, while supporting remote management and reducing operation and maintenance expenses.
• Easy integration: The VRS-UD350 LVDS/MIPI to IP network interface board is seamlessly compatible with SONY FCB-EV9520L, FCB-EV9500L and other camera modules, achieving “plug and play” through standardized protocols.
The drawback lies in that the video compression and codec process will introduce a slight delay (usually controlled within milliseconds), and the picture quality will be somewhat lost. Although it is close to lossless, it may be slightly insufficient for extremely demanding professional scenarios.
Iii. Decision-making Moment: How to Choose Based on Actual Needs?
Select the 3G-SDI interface board if:
Your cross-border meetings have extremely high requirements for picture quality, such as remote medical consultations and engineering drawing reviews.
Dedicated optical fiber lines have been laid or are easy to lay between the conference nodes.
Pursue a broadcast-level professional experience.
It mainly conducts point-to-point transmission and has no tolerance for system delay at all.
Ⅳ.Prefer VRS-UD350 LVDS/MIPI to IP network interface board if:
Your cross-border meeting needs to connect nodes from multiple different countries or regions.
Pursue the flexibility and convenience of deployment and hope to utilize the existing Internet network.
• Sensitive to cost, it is necessary to balance picture quality and cost-effectiveness.
The meeting scenarios are diverse and may involve mobile access or wireless networks.
Conclusion
In fact, in high-demand cross-border video conferencing systems, the 3G-SDI interface board and the VRS-UD350 LVDS/MIPI to IP network interface board are not always in opposition. A fusion solution is becoming increasingly popular: using a 3G-SDI interface board within the local meeting room to ensure lossless acquisition and transmission, and then converting the video signal into a network video signal through the VRS-UD350 LVDS/MIPI to IP network interface board for cross-border transmission via the Internet. This not only ensures the local picture quality but also takes into account the flexibility and feasibility of remote transmission.
