DVCAM—Digital Innovation

Digitization is opening up new avenues to success in many business areas. Nowhere is this more true than in professional video production, where evolving digital technology is bringing proven advances in image quality and equipment versatility as well as reducing operating costs.

DVCAM was born in 1996 as an extension of the consumer DV format, with which it is compatible. With its superb picture quality, excellent editing capabilities and multigeneration performance, DVCAM is the perfect choice of format in the highly competitive world of professional video.

The DSR-1P is a dockable recorder for a camcorder, offering outstanding performance in the acquisition

process. When the DSR-1P is combined with a Sony DXC-D30P or DXC-D30WSP Digital

Camera, it becomes the DSR-130P Digital Camcorder, providing a totally digital signal

path and perfect ClipLink™ operation. For complete versatility, the DSR-1P

incorporates both a Pro 50-pin analogue and a Pro 76-pin digital interface,

this dual interface enabling connection to both analogue and digital

cameras. The DSR-1P features a dual-size cassette mechanism that accepts

both mini and standard size cassette tapes without any special adaptor - a

first in the history of dockable recorders. With its superb performance and

operating flexibility, the DSR-1P meets all the requirements of video professionals.

Playback Compatibility with the

Consumer “D V”Format

The DVCAM format has been developed as an extended digital recording format for video professionals and is based on the DV format. However, it maintains playback compatibility with the consumer DV recording format and has the unprecedented advantage that both standard and mini cassettes can be used in the same machine. By using an increased track pitch, the DVCAM format gives higher reliability for professional editing.

The DVCAM Component Digital

Recording Format

The DVCAM format uses 8-bit component recording with a 5:1 compression ratio and sampling at the rate of 4:2:0 to provide superior picture quality and multi-generation capability. The DVCAM employs an intra frame compression scheme which is ideal for editing applications. Based on DCT (Discrete Cosine Transform) techniques, each frame consists of 12 tracks. Each track has ITI (Insert and Track

Information), Audio, Video, and sub code areas. The ITI, which is a reference signal for a precise tracking, and time codes on the Sub Code area assure highly accurate editing performance. This technique provides much greater operational flexibility, for example by minimizing dubbing limitations to allow more efficient and complex multi-layering.

High Quality Digital Audio and Audio Mode Selection

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

Excellent Performance from Professional

D VCAM Tapes

To gain the maximum performance from high density digital recording, new Advanced Metal Evaporated cassette tapes are used for DVCAM. These give superior quality to DVCAM recording by achieving an RF video output which is +4.5dB higher compared to that of Hi-8 metal evaporated tape. Higher durability is also ensured for professional editing applications by enhancing protection with a DLC (Diamond Like Carbon) coating. Each cassette has a built-in 16kbit IC memory which stores data to enhance editing efficiency. DVCAM cassettes are available in two sizes; the DVCAM Standard cassette provides a maximum recording time of 184 minutes and a DVCAM Mini cassette up to 40 minutes.
