Features Overview 1 Chapter Chapter 1 Overview Features The DSR-25 is a digital videocassette recorder using 1/4-inch tape. Offering the DVCAM™ digital recording format, the DSR-25 produces stable, superior picture quality by digitally processing and separating image signals into color difference signals and a luminance signal (component video). The DSR-25 can handle both NTSC and PAL color systems and is equipped with an analog interface as well as a digital interface enabling connection to a digital device such as a computer. The built-in color LCD monitor lets you check images easily. The main features of the DSR-25 are described below. DVCAM Format DVCAM is based on the consumer DV format, which uses the 4:1:1 component digital format (NTSC) or the 4:2:0 format (PAL), and provides a 1/4-inch digital recording format for professional use. For details, see "Compatibility of DVCAM and DV Format" on page 76 (GB). High picture quality, high stability Video signals are separated into color difference signals and a luminance signal, which are encoded and compressed to one-fifth size before being recorded to ensure stable and superb picture quality. Because the recording is digital, multi-generation digital dubbing can be performed with virtually no deterioration of quality. Wide track pitch The recording track pitch is about 15 µm, fully 50 percent wider than the DV format's 10 µm track pitch. Thanks to this feature, the DVCAM format fully meets the reliability and precision requirements of professional editing. High-quality PCM digital audio PCM recording makes for a wide dynamic range and a high signal-to-noise ratio, thereby enhancing sound quality. There are two recording modes: 2-channel mode (48 kHz sampling and 16 bit linear code), which offers sound quality equivalent to the DAT (Digital Audio Tape) format, or 4-channel mode (32 kHz sampling and 12 bit nonlinear code). 6 (GB) Chapter 1 Overview
