Sony FCB camera block
The SONY FCB-EV9520L full HD integrated camera module and HD-HDMI interface board have joined forces to create a professional high-definition video solution that integrates high-definition imaging, plug-and-play convenient deployment, precise and flexible control, and real-time stable transmission. This combination is easily adapted to multiple fields such as drone inspection, industrial precision detection, all-weather security monitoring, high-definition surgical field recording in medical surgical scenarios, and intelligent traffic dynamic tracking. It provides industry users with efficient full-chain support from image collection to transmission and landing, facilitating precise decision-making and intelligent upgrades in complex scenarios.
Many users, in pursuit of convenient image output or rapid data acquisition, often attempt to directly receive the image signal of the combination of SONY FCB-EV9520L and HD-HDMI interface board through their laptops. The result is that the image data cannot be displayed or transmitted normally.
The interface on the HD-HDMI interface board that pairs with the SONY FCB-EV9520L is HDMI, and the interface on the notebook is also HDMI. Then why can’t images be output? Danny Wong, a senior engineer at Xuanzhan Technology, often receives such requests for help.
I. Why use a laptop to receive video signals
1. Portability
Laptops, with their outstanding balance of portability and performance, have become the top choice in modern office work, testing, and data transmission fields. Its seamless switching ability between different scenarios and the significant improvement in work efficiency make it stand out among numerous tools and play an irreplaceable key role. With the help of appropriate conversion devices or interfaces, it is also easy to receive video signals from the camera module using a laptop, which greatly expands its application scope in video capture, monitoring, and multimedia production fields.
2. Success stories
When using the SONY FCB-EV9520L camera module in combination with the LVDS to USB3.0 video capture board, simply connect the two ends of the USB cable to the capture module and the USB interface of the laptop respectively. Then, the image and video signals captured by the SONY FCB-EV9520L camera module can be smoothly transmitted and presented on the laptop, achieving efficient and convenient video signal reception and processing.
Ii. Why can’t the HDMI interface board output images on laptops
Given the portability of laptops and the successful case of using the USB3.0 video capture board to clearly present the video signal of the SONY FCB-EV9520L camera module on the laptop, many users, when using the combination of the SONY FCB-EV9520L with the HD-HDMI encoding control board, It is also hoped that video signals can be presented with the help of laptops to further expand its application scenarios and ease of use.
But why did it end in failure in the end?
1. Analyze the success of the USB3.0 acquisition module
When the SONY FCB-EV9520L camera module is paired with an LVDS to USB3.0 video capture board, the USB on the capture module is the video signal output port.
(2) The USB port on a laptop is a content input port. We usually copy data to the computer through this USB interface. Therefore, by pairing it with an LVDS to USB3.0 video capture module, the video signal of the SONY FCB-EV9520L can be normally output to the laptop for display.
2. Summarize the failure of the HD-HDMI encoding control board
The HD-HDMI encoding control board that pairs with the SONY FCB-EV9520L camera module features an HDMI interface specifically designed for video signal output. It is used to transmit and present the image and video signals captured by the SONY FCB-EV9520L camera module to the receiving device.
(2) The HDMI interface of a laptop is essentially a content output port, used to project the screen image to an external monitor. The attribute that both are “output” interfaces determines that laptops cannot directly receive video signals from the camera module through the HDMI interface.
3. Solution
SONY FCB-EV9520L camera module +HD-HDMI interface board. If you want to output images on a laptop, you can use the high-definition HDMI to USB capture card to transfer the video signal of the camera module to the laptop through the USB interface and present it.
Summary
When receiving the video signal from the SONY FCB-EV9520L camera module, it is not advisable to make a blanket statement. It is essential to clearly determine whether the receiving end has the functional attribute of content input. Only when the receiving end has the corresponding input function can it be ensured that the signal can be correctly received and processed, thereby achieving the expected display effect.
In the application and scenario implementation of video products, no matter what problems you encounter, Xuanzhan Technology, which is both an officially authorized dealer of SONY (China) and has 16 years of practical experience in high-definition video secondary development, is sure to provide you with “protection and support”.
