質問: CVBS to IP Encoder Switches to Black-and-White After Weak Signal
I am experiencing some issues with the TO IP encoder. I am using it to convert the signal from an analog video receiver (VRX). When the signal quality is good, the image is excellent and in color. しかしながら, as soon as the signal from the receiver becomes weak for a short period of time, the converter board switches to black-and-white mode, and after that it is no longer possible to restore the color image automatically. How can this issue be resolved?

Thank you for your feedback. This issue is usually caused by unstable or weak CVBS video signals from the analog receiver. When the signal temporarily drops below the decoder threshold, some standard CVBS-to-IP encoder boards may lose color synchronization (PAL/NTSC chroma lock) and remain in black-and-white mode even after the signal recovers.
To help us confirm the exact cause, could you please send us a photo of the encoder board you are currently using?
We also recommend using our newer upgraded model, which is specially designed for weak and unstable analog video signals. It features improved low-signal locking and more stable color recovery performance.
