INTRODUCTION
The CV-503ZKMHDMI 2.0 & 12G SDI to 12G/6G/3G/HD/SD-SDI Converter with Audio Embedder
provides a professional way to convert HDMI 2.0 or 12G SDI to 12G/6G/3G/HD/SD-SDI in real time. The
conversion between SDI and HDMI is pure digital and guarantees no loss transformation for both audio
and video. Plus, with up to 8 channels audio support, 7.1 channel or 5.1 channel audio becomes available.
The CV-503ZKM provides one low jitter SDI output up to 12G and three other SDI outputs up to 3G
simultaneously to either support 12G UHD output and 4 3G FHD outputs. This converter is also equipped
with high quality analog stereo embedder to fit into more realistic applications. With versatile features
controlled by the built-in switch, CV-503ZKM makes the most popular SDI applications handy and
possible.
