Overview

Features

The PDW-F70 is a professional disc recorder supporting HD playback and recording with Professional Disc 1) media.

When you use this unit in combination with a nonlinear editing system, the FAM 2) function enables data file transfers between the unit and computers over the i.LINK interface, allowing the unit to be used like an external hard drive. Its compact design, which also permits vertical placement, saves installation space on the desktop.

The unit can be used as a player for video editing and program output, and as a recorder for nonlinear editing. For these applications, it can be connected to Sony nonlinear editors, monitors, and video equipment with HDSDI interfaces via its standard HDSDI I/O connectors. It incorporates a color LCD display, allowing you to check video and use the menu system without connecting an external monitor.

Features of This Unit

The principal features of this unit are as follows.

MPEG HD 1) codec

High-quality video and audio recording and playback

The MPEG HD codec provides video compression compliant with the MPEG-2 MP@HL standard. It enables HD 4:2:0 digital component file recording in the 1080i (1,080 effective scanning lines, interlaced) format currently in use by many broadcast facilities. Uncompressed PCM recording of 16-bit 48 kHz audio delivers a wide dynamic range with a high signal-to-noise ratio.

Video bitrates and audio channels selectable according to application

You can select the appropriate video bitrate for your application from three video bitrate modes: 35 Mbps (HQ: high quality mode), 25 Mbps (SP: standard mode), and 18 Mbps (LP: long-play mode). You can select 2-channel or 4-channel audio, with the ability to record 120 minutes or more of audio. If the audio channel modes are the same, different video bitrates can be mixed on the same disc.

Rich selection of recording and playback functions

Support for multiple frame frequencies

The unit can record and play back five different frame frequencies: 1080/59.94i (displayed as 60I), 50i (displayed as 50I), 29.97PsF (displayed as 30P), 25PsF, and 23.98PsF. The unit features a standard 2-3 pulldown function, and can output 60I when playing back a disc recorded in 23.98PsF.

HD downconvert function

The unit is provided with a downconvert function. HD disc playback signals can be downconverted to SD signals and then output as SDSDI or composite signals, or output via the i.LINK (DV) interface. This allows you to shoot and record masters in an HD environment, and to use SD nonlinear editors and monitors for editing and program output.

DVCAM upconvert function

The unit features an upconvert function, with the ability to upconvert to HD and output HDSDI signals when playing back DVCAM discs.

i.LINK (DV) output is also supported 1), allowing you to use nonlinear editors in a standard i.LINK (DV) environment.

1) Input (recording) is not supported.

Recording of proxy AV data

Proxy AV data is a low-resolution (1.5 Mbps video, 64 kbps per audio channel), MPEG-4 based version of a full-
