Intr oduction This section provides an overview of the DSC 3G-HD A and DSC HD-3G A scalers, covering the following topics: • About this Guide • About the DSC 3G-HD A and DSC HD-3G A • Features .
Featur es DSC 3G-HD A • 3G-SDI, HD-SDI, and SD-SDI to HDMI video scaling — Provides high quality conversion of signal format and video resolution with audio embedding.
Both Models • Advanced scaling engine — Image scaling and video format conversion are performed at 30-bit precision for enhanced color accuracy and pictur e detail. High performance deinterlacing for 1080i signals from HD sour ces delivers optimized image quality .
• Integrated audio delay — The audio output is automatically delayed to compensate for latency introduced by the video pr ocessing. • Signal presence confirmation — Pr ovides real-time verification of status for the digital video input and output through fr ont panel LEDs or RS-232.
Rear Panel Connections This section provides a description of the DSC 3G-HD A and DSC HD-3G A r ear panel connectors and instructions for cabling. T opics include: • Rear Panel Connections • Secur.
