Synchronization Indicators
True Rate
True Sample Rate shows the speed at which that Dream II is running. It also shows the real frame rate,
after adjusting for Pull Up/Down setting.
Video Detect
The Video Clock Detected indicator is green when a valid Video Clock reference is detected and red
when Video Clock is missing or invalid.
Seeking Lock
The Seeking Lock indicator is green when seeking lock, and red when not in use.
Sync
The Sync indicator is green when a valid Clock Sync Source reference is detected, and red when the
Clock Sync Source is missing or invalid.
Progressive Detect
SX-20 supports both Progressive and Interlaced clocks. If the Progressive Clock Detect indicator is
green, a Progressive Clock reference has been detected and is being used as the primary sync
reference.
Clock In Range
The Clock In Range indicator is green when the Clock reference is in range and red when the clock
reference is out of range.
Position Sync
When synchronising with an external machine such as a video machine, audio recorder or digital audio
workstation, a positional source allows the machines to “tell” each other where they are. The Position
Sync Source indicator is green when a valid Position Sync Source reference is detected, and red when
the Position Sync Source is missing or invalid.
Synchronization Details
Constellation-XT can track the position and motion of external transports such as a video tape recorder,
timecode-striped audio tape or a timecode generator. The disk recorder will play in time with the Master
Timecode source so that sound and picture coincide.
Position
This is an absolute location reference to a sequence of pictures or audio. It is used to determine
whether the disk recorder is playing the right part of its Project. For video, position reference is usually
provided by 9 pin (Sony protocol from an RS-422 port). For audio tapes LTC is normally used (though 9
pin is also a possibility).
Motion
The motion of an external machine is a measure of its speed, and the disk recorder must move at the
same speed to remain in sync. This translates into producing the correct number of samples every
second, which is called the Master Clock rate. This can be locked to a Digital Word Clock, a video signal,
