INTRODUCTION

HDV and DV format

This unit records in HDV or DV format.

DV format is a standard for recording SD (Standard-Definition) video onto DV cassettes or mini DV cas- settes.

HDV format is a standard for recording HD (High-Definition) video onto DV cassettes or mini DV cas- settes.

The two HDV recording formats are HDV 720p and HDV 1080i. HDV 720p : 720p (720 effective scanlines, progressive scan) HDV 1080i : 1080i (1080 effective scanlines, interlace scan) This unit supports the HDV 720p format.

„HDV and DV signal input/output

HDV signals and DV signals are input/output from the IEEE1394 terminal. HDV signals from the IEEE1394 terminal are recorded in HDV format. DV signals from the IEEE1394 terminal are recorded in DV format.

Recorded HDV signals or DV signals are output from the IEEE1394 terminal during playback.

Digital audio is also input/output from the IEEE1394 terminal, together with HDV signals or DV signals. The front panel IEEE1394 switch must be set on the front panel, according to whether the input/output signal from the IEEE1394 terminal is in HDV format or DV format.

When the input signal or playback signal is in HDV format, the front panel HDV display is lit. Analog signal input is digitally converted and recorded in DV format.

480/60i: 480 effective scanlines, 60-field interlace scan

„Recording time

The recording/playback speed for HDV format is SP mode only.

Though DV format recording and playback speed has SP and LP modes, this unit supports SP mode only.

The cassette recording time is the same for HDV and DV format.

„HD signal format

This unit is compatible with both 60Hz and 50Hz HD signal formats. The HDV signal format must be set on this unit, according to whether the input/playback HD signal format is 60Hz or 50Hz.

(Set this using 60/50 SEL in the SYSTEM [2/2] Menu screen.)

Menu settings on this unit can be checked by whether the front panel 60 or 50 indicator light is lit.

„HD video output

HD video is output from the HDMI OUT terminal and the COMPONENT OUT terminal.

HDMI OUT terminal : Outputs HD/SD digital video and digital audio.

This is connected to a monitor with an HDMI terminal. (HDMI : High Definition Multimedia Interface)

COMPONENT OUT terminal: Outputs HD/SD analog video. Does not output audio.

This is connected to an HD-compatible monitor with COMPONENT input terminal.

zThe video format to output from the HDMI OUT terminal and the COMPONENT OUT terminal can be selected using OUT FORMAT [60]/OUT FORMAT [50] in the VIDEO Menu screen.
