Features
The DSR-1500A/1500AP is a 1/4-inch digital videocassette recorder using the DVCAM™ digital recording format.
The unit is equipped with an i.LINK/DV* interface as standard, so that it can be used as a low-cost, compact feeder, player or viewer in a non-linear editing system** without requiring any optional boards. When using the unit as an editor, the optional boards available for the unit allow you to select required input signal formats.
The unit is playback-compatible with tapes recorded in DV format (excluding tapes recorded in LP mode) as well as DVCPRO (25 Mbps) format. Playing back such tapes on the unit does not require any adapter.
These and other features of the unit make it suitable for use under diversified conditions. It can be used, for example, for desk-top editing or for such applications as electronic news gathering (ENG) and non-linear editing aboard outside broadcast vans, at production houses or at broadcasting stations.

**Non-linear editing: This is an editing method that uses video and audio signals digitally encoded and recorded on a hard disk as digital data. When compared with conventional (linear) editing methods, non-linear editing offers vastly improved efficiency in editing operations, for example, by eliminating tape transport time.
The following are the principal features of the unit.
DVCAM Format
DVCAM is a professional 1/4-inch digital recording format developed by Sony from the consumer DV component digital format.
High picture quality and high stability
Video signals are separated into color difference signals and luminance signals, 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 dubbing can be performed with virtually no deterioration of quality.
Wide track
The recording track width is 15 µm, 50% wider than the 10 µm of the DV format. This ensures adequate reliability for professional use.
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 quantization), which offers sound quality equivalent to the DAT (Digital Audio Tape) format, or 4-channel mode (32-kHz sampling and 12-bit quantization).
Superior playback compatibility with DV and DVCPRO (25 Mbps) formats
Tapes recorded in DV format (excluding the tapes recorded in LP mode) as well as DVCPRO (25 Mbps) format can be played back on this unit without requiring a cassette adapter. You can use the recordings on such tapes as source material for editing, applying such functions as the jog audio and digital slow-motion playback as required. Using the material, editing can be carried out to single-frame precision.
The unit can also be used for recording in DV format (in SP mode only).
