In the field of video transmission and control, multi-device compatibility has long been a headache for users. Older devices only support CVBS analog signals, while new devices generally adopt SDI or HDMI digital interfaces. The “generation gap” between the two makes system upgrades complex and costly.
Xuanzhan Technology, a provider of high-definition video secondary development solutions, brings you a revolutionary product – the SDI/HDMI/CVBS 3-in-1 Interface Board. With the design concept of “one board with multiple interface outputs”, it solves the compatibility issue of multiple devices and enables seamless integration of old equipment with new systems.
I. Why is a SDI/HDMI/CVBS 3-in-1 Interface Board needed?
1. Compatibility issues with old equipment
Many industries (such as security monitoring, broadcasting and media, and industrial inspection) are still using old cameras or equipment that support CVBS output. However, modern display terminals, recording devices, or management systems generally use SDI or HDMI interfaces, resulting in the inability to directly transmit signals.
2. High cost of system upgrade
If new products supporting digital interfaces are purchased to replace old equipment, it will incur high procurement costs. If converters are separately configured, not only will the number of devices increase, but also problems such as signal delay and compatibility risks will be introduced.
3. Flexible Adaptation to Multiple Scenarios
Different projects have varying interface requirements. For instance, outdoor monitoring requires long-distance transmission (SDI), conference room presentations need high-definition output (HDMI), and the maintenance of old systems demands analog signals (CVBS). A single interface device is hard-pressed to meet such diverse demands.
Ⅱ. SDI/HDMI/CVBS 3-in-1 Interface Board: Solving User Pain Points
Xuanzhan Technology, a provider of high-definition video secondary development solutions, has designed the SDI/HDMI/CVBS 3-in-1 Interface Board specifically to address the aforementioned issues. It integrates the three mainstream interfaces of SDI, HDMI, and CVBS, supporting the simultaneous output of three video signals, truly achieving “reusing old equipment and ensuring the stable use of new equipment.”
Core Function Highlights
1. Multi-interface coverage, wider compatibility
Input support: The SDI/HDMI/CVBS 3-in-1 Interface Board supports standard LVDS signal input without the need for additional converters.
Flexible output: The SDI/HDMI/CVBS 3-in-1 Interface Board can simultaneously output SDI, HDMI, and CVBS signals, adapting to different display terminals or recording devices.
Automatic recognition: After connecting to a high-definition integrated camera core, no settings need to be made to the camera core, and it automatically recognizes high-definition SDI video signals.
2. High-definition encoding, lossless picture quality
The SDI/HDMI/CVBS 3-in-1 Interface Board supports 1080P@60Hz high-definition encoding for SDI and HDMI signals, providing high clarity and accurate color reproduction.
Low latency transmission technology ensures smoothness in real-time monitoring, meeting presentations, and other scenarios.
3. Remote Control and Integrated Management
The SDI/HDMI/CVBS 3-in-1 Interface Board provides RS-485 standard serial port control, and is optionally equipped with RS-232 and TTL-232 control. It supports remote parameter adjustment (such as resolution, frame rate, and encoding format) through serial port debugging software. At the same time, it is convenient for communication between the device and a computer or MCU, expanding the application range of the product.
III. Application Scenarios: Covering the Demands of All Industries
1. Upgrading Security Monitoring
Old analog cameras can be upgraded through an SDI/HDMI/CVBS 3-in-1 Interface Board, which outputs CVBS analog signals and connects to traditional display devices. It supports simultaneously outputting digital high-definition video signals to SDI and HDMI display devices.
2. Radio and Television Media and Live Streaming
Compatible with both old-style cameras (CVBS output) and new high-definition devices (HDMI/SDI output), and after unified encoding, push to live streaming platforms to reduce equipment update costs.
3. Industrial Inspection and Medical Imaging
Convert the analog signals of old endoscopes and microscopes into digital signals and output them via HDMI to high-definition displays to enhance inspection accuracy and operational experience.
4. Education and Enterprise Conference
Supports mixed output of multiple signals such as SDI, HDMI, and CVBS, and is managed uniformly through the control board to create an intelligent conference room.
Summary
The SDI/HDMI/CVBS 3-in-1 Interface Board is an important innovation in the field of video transmission. It effectively resolves the compatibility issue among multiple devices and offers users a more flexible and economical solution. With the continuous development of video technology, this multi-functional and highly compatible device will have broader application prospects. For this reason, Xuanzhan Technology has also developed a mini SDI/HDMI/CVBS 3-in-1 Interface Board, which features more comprehensive functions and a smaller size, expanding the application range of high-definition integrated camera modules even further.
