Recording Formats and Input/Output Signals
Differences among HDV 1080i, DVCAM, and DV formats
The following table shows differences among the HDV
1080i, DVCAM, and DV formats.
1) For audio signal recording, there are two modes: locked mode and
unlocked mode. In the locked mode, the audio sampling clock signal and
video sampling clock signal are synchronized. In the unlocked mode
adopted for the consumer DV format, the audio and video sampling clock
signals are independent. The locked mode is preferable to the unlocked
mode in compatibility with higher level formats. The locked mode is also
preferable in terms of digital processing during audio editing and for
creating smooth audio joins.
2) This unit does not support 16 bits: 32 kHz, 16 bits: 44.1 kHz recording.
3) This unit performs recording in locked mode.
4) For the 60i mode, this unit has extended functionality to allow DF/NDF
selection, and to allow user bit data to be set.
5) Four channels when the 2-channel option is added (this unit supports 2
channels).
For usable cassettes, see “Usable Cassettes” (page 40).
Input and output signals in E-E mode
When the HVBK-1505 option board is installed, the
relationships between input signals and output signals in
E-E mode is as shown in the following tables.
• Select the input signal with the INPUT SELECT buttons
in the video/audio input selection section on the front
panel.
• Select the analog video signal output with the
INTERFACE SELECT >VIDEO OUTPUT menu item
.
