Kiloview CV180 Broadcast-Grade SDI to HDMI/VGA/AV Video Converter

The Kiloview CV180 Broadcast-Grade SDI to HDMI/VGA/AV Video Converter (often cataloged as the KV-CV180) is an industrial, multi-functional scan converter, scaler, and frame-rate synchronizer.

While its sibling (the CV190) handles multi-format ingest into an SDI workflow, the CV180 does the exact opposite: it acts as a central downstream breakout box. It takes a single professional baseband SD, HD, or 3G-SDI coaxial broadcast feed, normalizes it through a dedicated 10-bit image processor, and outputs it to a variety of digital and analog consumer display formats simultaneously.

Core Engineering and Operational Features

• One Input to Multiple Output Multi-Streaming: The chassis features a 75-Ohm BNC input that accepts SD-SDI, HD-SDI, and 3G-SDI signals. It can drive up to three outputs simultaneously: one dedicated, zero-latency physical SDI Loop-Out (BNC), plus any two of its converted output formats (HDMI, VGA, or analog Composite AV) at the same time.

• Hardware Scale and Frame-Rate Conversion: Unlike basic, passive adapter plugs that fail if a display doesn't support a specific broadcast frame rate, the CV180 has a built-in professional image processing chip. It features smart up/down-scaling and hardware frame-rate transformation, allowing you to convert any standard SDI resolution (like 1080i50 or 1080p59.94) into a custom, self-defined target resolution optimized for commercial projectors or legacy IT monitors.

• 10-Bit YUV 4:2:2 Image Enhancement Matrix: To ensure high-quality color accuracy and signal fidelity, the conversion engine maintains a 10-bit YUV 4:2:2 processing pipeline. Before mapping the video to the consumer outputs, the chip applies hardware-level 3D noise reduction, smart de-interlacing (converting 1080i fields to clean progressive frames), and granular color-conditioning layers.

• Flexible Dual-Track Audio De-Embedding: The CV180 automatically de-embeds digital audio tracks directly from the incoming SDI stream. This audio can be passed directly through the synchronous digital HDMI connection or routed into an independent, dual-track analog stereo output for direct PA system or audio mixer integration.

• On-Screen Broadcast Toolsets: Engineered for master control rooms and engineering stations, the software layer can generate helpful graphical overlays directly onto the video output. Technicians can toggle real-time signal parameter prompts, an OSD menu interface, Safe Area margins, center crosses, and basic VU audio meters.

• Versatile Control Topology (IR Remote & USB): The factory default output combination is set to HDMI + CVBS (AV). Operators can dynamically change active video layouts, adjust aspect ratios, or calibrate color profiles (brightness, contrast, saturation, hue) using the included infrared remote control or by connecting a PC to its USB configuration port.

💡 Operational Engineering Tips for the CV180

The Long-Distance SDI Signal Recovery Rule: The CV180 features an integrated high-performance SDI Cable Equalizer (EQ) and clock recovery circuit. This allows the unit to act as an active repeater, cleaning up attenuation and distortion caused by long cable runs before converting the signal. When deploying industry-standard Belden 1694A (or equivalent 75-Ohm broadcast coaxial) cabling, the chip can cleanly recover signals at distances up to:

• SD-SDI: ~400 meters (1,312 feet)

• HD-SDI: ~200 meters (656 feet)

• 3G-SDI: ~120 meters (393 feet)

Always ensure high-quality 75-Ohm BNC terminations are used; poor-quality connectors or cheap 50-Ohm cables will dramatically slash these distances and cause signal drops.

• Fixing Geometry Distortion (Stretching vs. Pillar-Boxing): By default, the CV180 uses a "Stretch" mode when cross-converting resolutions. If you feed an old standard-definition broadcast signal (like a 4:3 aspect ratio 576i or 480i feed) and convert it straight to a modern 16:9 1080p HDMI display, the image will look horizontally distorted. Use the infrared remote control to enter the menu and adjust the aspect ratio mode to apply pillar-boxing (adding black bars on the sides) or letter-boxing to maintain correct, undistorted geometric proportions.

• Troubleshooting Output Display Issues via Factory Reset: If a technician accidentally configures the CV180 to a custom resolution or frame rate that the local monitor cannot read, the screen may go black or display an "Unsupported Format" error, blocking access to the menu. To recover instantly without a computer, point the infrared remote control at the CV180's IR receiver, press and hold the POWER/RESET button for one full second, release it, and press it once more. This instantly reverts the box back to its factory default output layout (HDMI+CVBS out at a highly compatible 720p60 baseline).
