Playback Compatibility with Home-Use "DV" Format

The DVCAM digital recording format for video professionals is an extension of the consumer DV format. The DVCAM format offers playback compatibility with the consumer DV recordings, in addition to the unprecedented capability to use both standard and mini cassette on the same machine.

The DVCAM Component Digital Recording Format

The DVCAM format uses 8-bit component digital recording with a 5:1 compression ratio and sampling at the rate of 4:1:1 to provide superior picture quality and multi-generation capability.

High Quality Digital Audio and Audio Mode Selection

The DSR-1 provides two selectable audio channel modes, two channels and four channels. In order to ensure superb audio performance with a wide dynamic range and an excellent signal-to-noise ratio, the PCM (Pulse Code Modulation) digital stereo recording system is used in both modes; 2CH of 16 bit, 48kHz sampling frequency and 4CH of 12bit, 32kHz sampling frequency.

Dual Cassette Mechanism

The DSR-1 accepts both DVCAM Mini cassette tapes and DVCAM Standard cassette tapes without any adaptor.

Dual Interface Mechanism Gives Choice of Dockable Cameras

The DSR-1 has both a Pro 76-Pin Digital and a Pro 50-pin connector which allow direct connection with Sony's digital and analog cameras: DXC-D30 and DXC-327b to meet the demands of a variety of shooting situations.

Low Power Consumption

Owing to low power consumption of only 26W, one fully charged Sony NP-1B battery gives continuous operation for approximately 60 minutes when docked to the DXC-D30.
