1. TC-IN/TC-OUT: Can receive or send out the SMPTE-standard LTC timing signal. This means that you can share time code with an external device (such as a DAT recorder for dual-system sound) or from camera to camera.
For "Time Code In", simply connect the device generating the desired time code and allow the synchronization to stabilize. This usually takes about 10 seconds. Once this is done, the cable connecting the two devices can be removed and the time code synch will be maintained as long as the camera is not turned "Off" or switched into "VCR/Play" mode. The synch will also be lost if you change the FRAME RATE. In SD mode ("Standard Definition") at 24F, you will not be able to import time code at all.
For "Time Code Out", you must go into the menu and activate the T.CODE OUT option on the SIGNAL SETUP page. Then, you can hook up another device to receive the time code that is being generated by the camera (or that has been imported from yet another device in the chain).
When sharing time code, only the FREE RUN mode will be useful; it is the only mode that runs continuously, regardless of whether or not the operator has pressed "Record". This FREE RUN option is found in the menu, within the TIMECODE sub-heading on the CAMERA SETUP page.
Note: No matter what frame rate the XL H1 is set to, in 60i mode the Time Code signals are always 29.97DF and in 50i mode (optional) it is always 25.
2. GENLOCK: Short for "Generator Lock", Genlock is a signal sent from an external source (such as a sync generator, switcher or other camera) that ensures the seamless interaction between images by making sure that the different video signals are all being "generated" with the same timing, in sync with one another. This is an absolute must in a "live" broadcast environment, for example, when images must be edited on the fly without visibly "jumping".
Each video signal has its own vertical and horizontal phase values (its own unique "timing", when the scan-lines are actually being "drawn" across the screen). The Genlock reference can be as simple as another video signal, which will "teach" its timing to the new signal and thus synchronize the two so that the video images are being drawn exactly in unison. Thus, there will be no "bump" or "stutter" during transitions when intercutting or overlapping images from multiple camera sources.
Activate this feature by going into the EXT. SYNC option on the SIGNAL SETUP page of the menu. Select either "Genlock" or "Genlock + TC", depending on your specific input situation. Use the GENLCK ADJST option (on the same menu page) to match the phase of your reference signal.
3. HD/SD SDI: The Serial Digital Interface (SDI) terminal of the XL H1 is able to deliver full resolution uncompressed HD/SD SDI at a 4:2:2 color space.
This terminal is also capable of transmitting the lower bit-rate SD signal from the camera even when the XL H1 is set for HD or recording HD to tape.
What's more, since the signal is transmitted via coaxial cable, you can run 100 meters without worrying about any lost data, which is ideal for situations when the camera may be up in a crane or traveling during a long walk around shot.
When using the SDI terminal to output a signal, make sure that the SDI OUTPUT is set to "On" in the SIGNAL SETUP page of the menu. Also, when outputting the HD signal, set the SDI SPEC to "Auto".
