Description : Outputting images recorded in HDV standard.
Using the HD/SD SDI Terminal


You can output the following two kinds of signals from the HD/SD SDI terminal.
- Output video captured in HDV standard as uncompressed HD standard signal (the signal will be compressed for tape playback).
- Convert video captured in HDV standard and output it as SD standard signal.
* About the SDI (Serial Digital Interface)
SDI is a video signal transmission standard that enables you to transmit uncompressed digital visual signals and digital audio signals via one BNC cable.
For high-definition camcorders, you can output uncompressed high-quality images (1,920 x 1,080) to other equipment while shooting.
Depending on the equipment the camcorder is connected to, the audio signal can be superimposed and then transmitted along with the video signal.

The formats of transmitted images will vary as follows according to the standard of the output signal.
- Recording mode
Output HD standard signal: HD (1,920x1,080) in 16:9
Convert to SD standard signal and then output: SD in 4:3
- Playback mode
Output HD standard signal: HD (1,440x1,080) in 16:9
Convert to SD standard signal and then output: SD in letterbox 4:3


Connection method
* A BNC cable is necessary to connect the camcorder to other equipment. It is not supplied with the camcorder. Please use a commercially available BNC cable.
Connect the BNC cable to the camcorder's HD / SD SDI terminal.
If necessary, connect the supplied stereo cable to the camcorder's A / V terminal.
Set the Video Output Selection Switch to the A/V1 position.
Press the MENU button, and turn the SELECT / SET dial to select SIGNAL SETUP.
Turn the SELECT / SET dial to select SDI OUTPUT and press the dial.
Turn the SELECT / SET dial to select ON.
* After setting the SDI OUTPUT to ON, the embedded audio output will be enabled automatically. (Please refer to the following information for details on embedded audio.)
Turn the SELECT / SET dial to select SDI SPEC.
- Select AUTO to output uncompressed HD standard signal.
- Select SD LOCKED to convert video and output it as SD standard signal.
When converting video to SD standard signal, turn the SELECT / SET dial and set LETTERBOX to ON, and then press the dial. When output the HD standard signal, set LETTERBOX to OFF.
Press the MENU button.


Embedded Audio
Embedded audio refers to the superimposing of audio with the video signal being output from the HD/SD SDI terminal.
Please refer to the following information for details on signal standard and sampling frequency settings.

Note: Locked audio and unlocked audio
- Locked audio refers to the method that synchronizes the sound signal with the visual signal. The audio sample clock is locked to the video sample clock. Audio and video will be matched up even for longtime recording.
- Unlocked audio refers to the method that does not synchronize the sound signal with the visual signal. The audio sample clock is not locked to the video sample clock. Audio and video may not match up for recordings that last for a long time.
