1-1 Features

The MSW-M2100/M2100P is a digital videocassette player based on the MPEG IMX format.

This unit uses large scale integrated circuits for signal processing, and has a simple internal construction, allowing it to provide functionality at least equivalent to a conventional VTR in a compact (4U size), lightweight, and low power consumption design.

It not only offers playback in MPEG IMX format, but can also play back tapes recorded in Betacam SX format, analog Betacam format, or digital Betacam format.

MPEG IMX format

The MPEG IMX format uses the same 12.65-mm width tape as the conventional Betacam series. This economical format uses 50 Mbps high image quality MPEG-2 compression, and offers up to three hours of recording.

The video signal compression, as in the Betacam SX format, uses MPEG-2, and compressed data can be passed directly without loss of quality, not only to VTRs, but also to other devices with MPEG support, such as nonlinear editors or servers. There is thus high compatibility with the next generation of digital television formats supporting MPEG-2.

The audio tracks allow up to eight channels to be recorded, and this also provides future extensibility for multichannel, multilingual broadcasting, data broadcasting, and so on.

High-performance heads and compatibility playback function

The newly developed high-performance heads and dynamic tracking (DT) technology provide high- density playback in narrow tracks with high reliability. In addition to the MPEG IMX playback heads, this unit is also equipped with Betacam SX format playback heads, and analog Betacam DT heads, to provide compatibility playback functions, and allowing a wide variety of recorded resources to be used effectively.

High-precision digital signal processing and range of interfaces

The MPEG IMX VTR digital video signal processing uses 4:2:2 component video signals complying with ITU-R Rec 601/SMPTE 259M, which are compressed with ISO/IEC 13818-2000 MPEG-2 compression. While supporting a wide range of signals for output, all of the VTR internal processing is digital, providing high stability and reliability.

The audio signals, similarly, are based on AES/EBU format, and are subjected to digital signal processing while still uncompressed.

The following interfaces are standard equipment, for ease of connection to different external devices.

•Analog composite signal input/output

•Analog component signal output

•Analog audio signal output (4 channels)

•Serial Digital Interface SMPTE 259M output (component digital video/audio, 8 channels)

•AES/EBU serial digital audio output (8 channels)

•SDTI-CP SMPTE 326M output (MPEG video/audio data)

•Time code output
