tvONE C2-2755 – Video Scaler Plus with HDMI, DVI-U, and SDI Input

Product Overview

The tvONE C2-2755 is a compact, full-featured video scaler designed for AV integrators deploying multi-format source switching and scaling in conference rooms, classrooms, and presentation environments. It accepts HDMI, DVI-U, 3G-SDI, VGA, composite, and S-Video inputs, outputs HDMI and DVI-U, and includes a 4x1 audio switcher with analog audio output. Output resolutions span from 800x600 to 1920x1200 at 60 Hz, covering the full range of modern HDTV and PC display targets. The OLED display and intuitive 15-button front panel simplify local operation, while IP and RS-232 interfaces support third-party control.

Product Description

The C2-2755 handles up, down, and cross conversion between its input formats with frame rate conversion and pulldown support, making it suitable for environments mixing legacy analog sources with modern digital displays. The auto-switching function detects an active input and selects it automatically, eliminating manual source selection — particularly useful in unsupervised meeting rooms. The unit supports Genlock for synchronizing output to an external reference, audio embedding and de-embedding on HDMI, SDI, and DVI-U, and advanced compositing features including keying and custom image resizing. CORIO Control software — a graphical Windows replica of the physical unit — provides remote configuration and operation via IP. Twelve selectable presets store user-defined configurations including both basic controls and advanced features like PIP and keying. The C2-2755 also stores up to five still images and five logos for use in presentations. An optional rack-mount kit is available for 19-inch rack installation. Latency is 1 to 2 frames across all conversions.

Key Features

• Multi-Format Input Support — Accepts 1x Composite (BNC), 1x S-Video (4-pin DIN), 1x HDMI, 1x 3G-SDI (BNC), 1x VGA, and 1x DVI-U covering composite, component, HDMI, DVI, and VGA signals.
• HDMI and DVI-U Outputs — Outputs HDMI and DVI-U at resolutions from 800x600 (SVGA) to 1920x1200 (WUXGA) at 60 Hz covering all standard PC and HDTV display targets.
• Auto-Switching with Input Detection — Automatically selects an active input on connection, ideal for rooms without dedicated AV operators.
• Frame Rate Conversion and Pulldown Support — Handles SD-SDI (525i/625i), HD-SDI (720p, 1080i, 1080p at standard rates), and 3G-SDI (1080p at 50/59.94/60 Hz).
• Genlock for Synchronization — Synchronizes output to external reference signals for integration into synchronized AV or broadcast systems.
• Audio Embedding and De-Embedding — Audio is embedded/de-embedded on HDMI, SDI, and DVI-U; three analog audio terminal inputs and one 3.5 mm jack provide flexible connectivity.
• CORIO Control Software — Windows software provides a graphical interface mirroring the physical unit for remote configuration via IP.
• 12 User Presets — Stores twelve configurations including basic and advanced settings (PIP, keying, custom resizing) for rapid recall.
• SDI Jitter Performance — SD-SDI less than 0.1 UI; HD-SDI less than 0.2 UI; 3G-SDI less than 0.3 UI.
• Optional Rack-Mount Kit — Converts the desktop unit to 19-inch rack installation.

Typical Applications

• Conference rooms and meeting spaces requiring multi-format source switching to a single display
• Classrooms and training facilities with mixed HDMI, VGA, and composite sources
• Broadcast and production environments requiring 3G-SDI input scaling to HDMI monitors
• Corporate boardrooms with diverse laptop and presentation source types
• House of worship presentation systems handling multiple source formats
