Standalone video encoder for CVBS video input and compressed data output in PCM (CLK + data) format

Overview:
The CVBS Video Encoder with PCM output is a high-performance, compact, and robust video encoding solution designed for professional analog video applications where transmission over serial interfaces is required. Specifically engineered for airborne, UAV, and ground-based systems, this encoder converts SD analog video signals into compressed digital data, output in Pulse Coded Modulation (PCM) format via RS-422 or CMOS-level TTL, with precise clock synchronization.

Built for environments that demand reliability, low latency, and configurability, this encoder supports JPEG2000 wavelet-based compression, providing high-quality video with robust error resilience over serial links. It is suitable for integration into airborne payloads, mobile vehicles, or any application where compact size, low power consumption, and environmental tolerance are critical.

The encoder can function as a standalone device or be paired with a compatible decoder for end-to-end video transmission solutions. It is also compatible with software decoders such as VLC for H.264 streams or OpenJPEG for JPEG2000, offering flexibility for mission-specific requirements. This product is particularly designed for users who require analog SD video (PAL) input and compressed output in RS-422 PCM format for further processing, storage, or transmission over serial data links.
