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

The category Kiloview Broadcast-Grade HDMI/VGA/AV to SDI Video Converter refers explicitly to the Kiloview KV-CV190 (often cataloged simply as the CV190).

Unlike standard, cheap "adapter bricks" that only handle a single fixed connection, the CV190 is an industrial, multi-format hardware scan converter and frame-rate synchronizer. It is engineered for master control rooms, broadcast trucks, and projection grids to ingest virtually any legacy or modern analog/digital video signal, normalize it through a 10-bit processing chip, and output a clean, stable baseband SDI signal.

Core Engineering and Operational Features

• Universal Legacy & Modern Input Ingest: The CV190 houses an analog and digital input array on its rear panel. It natively accepts HDMI 1.4 (digital), standard VGA (analog computer), and AV / CVBS (analog composite via BNC). It can also ingest YPbPr component video utilizing an included VGA-to-Component adapter cable.

• Dual Simultaneous SDI Outputs: Driven by an enhanced SDI line driver, the unit features two parallel 3G-SDI BNC outputs. This hardware layout allows engineers to split a single incoming source to two separate destinations—such as a production switcher and a local engineering monitor—without requiring an external SDI distribution amplifier.

• Hardware Scale and Frame-Rate Up/Down Conversion: The internal processing core functions as an independent hardware scaler. If a presenter plugs in an unusual computer resolution over VGA (e.g., a VESA standard 1024×768 or non-standard frame rates), the CV190 will hardware-convert, scale, and cross-convert the signal into a fixed broadcast standard (such as 1080p60, 1080i50, or 720p60) to keep downstream switchers from glitching.

• 10-Bit YUV 4:2:2 Color Processing Matrix: To satisfy strict broadcast television standards, the conversion pipeline uses a 10-bit YUV 4:2:2 color processing matrix. It applies automatic 3D noise reduction, interlace-to-progressive conversion, and color conditioning layers to prevent color bleeding or artifacting on analog composite feeds.

• Flexible Audio Embedding Matrix: The CV190 can extract embedded digital audio from an HDMI input source, or it can ingest external audio via a physical 3.5mm analog stereo jack. The internal chip automatically digitizes and embeds this analog audio layout directly into the synchronous SDI output stream.

• Dual Control Schemes (Remote & USB): The converter can operate completely headless via automatic input detection, but technicians can fine-tune advanced settings (like aspect ratio adjustments, overscan/underscan cropping, brightness, and contrast) using an included infrared remote control or by connecting a laptop to its mini-USB port.

💡 Operational Engineering Tips for the CV190

The Long-Distance SDI Cable Threshold Rule: The CV190's integrated active line equalizer and clock recovery circuit are optimized for extended cable runs, but performance depends entirely on the gauge and quality of your coaxial runs. When broadcasting over industry-standard Belden 1694A (or equivalent 75-Ohm broadcast-grade) cables, your maximum transmission distances before structural signal attenuation occurs are:

• Standard Definition (SD-SDI): Up to 400 meters (~1312 feet)

• High Definition (HD-SDI): Up to 200 meters (~656 feet)

• 3-Gigabit Full HD (3G-SDI): Up to 120 meters (~393 feet)

If your cable runs exceed these limits, you must insert an active SDI inline repeater or transition the link over to an optical fiber converter.

• Fixing Aspect Ratio Issues for Retro Gaming or Legacy AV: When converting old composite 4:3 video signals (like an old VCR tape or retro console video output) to modern 16:9 SDI production layouts, the default behavior of basic adapters is to stretch the image horizontally, distorting the frame. Use the CV190's infrared remote control or USB software tool to override the output aspect ratio. You can force the converter to apply pillar-boxing (adding black bars to the left and right), maintaining the original 4:3 geometric proportions within a 1080p broadcast container.

• Eliminating Ground Loop Audio Hum: When connecting a computer's analog headphone jack to the CV190's 3.5mm input while using the VGA port, you may experience a loud, low-frequency 50Hz/60Hz ground loop hum in your audio stream. This happens because the computer and the video converter are plugged into different electrical circuits. To instantly fix this, always try to grab audio digitally by running an HDMI cable instead, or pass the 3.5mm analog cable through a cheap, passive Ground Loop Audio Isolator before plugging it into the converter.
