| What does VITC stand for? |
|
Definition
| Vertical Interval Time Code |
|
|
Term
|
Definition
| This form of SMPTE TC is used only on Video recordings as it is recorded as part of a Video frame in the vertical blinking section of the picture frame/field. It is recorded twice (to avoid any drop-outs or other problems) onto any of the unused lines within the vertical blinking interval. |
|
|
Term
| Why is VITC used over LTC? |
|
Definition
| For slow motion purposes. |
|
|
Term
| True or False LTC can not be read under 1/10 to 1/20 speed. |
|
Definition
|
|
Term
| True or False VITC uses up an audio track |
|
Definition
| False VITC does not use up an audio track |
|
|
Term
VITC does not use a self-clocking modulation signal.
True or False |
|
Definition
True
It uses a more basic type of modulation called Non Return to Zero (NRZ). It is part of a highly synchronized video signal. |
|
|
Term
True or False
You can stripe LTC at any time? |
|
Definition
True
LTC can be stripped at any time |
|
|
Term
True or False
In VITC, you have to stripe at the same time as the video signal. |
|
Definition
|
|
Term
| How many bits does VITC word use? |
|

|
Definition
|
|
Term

|
Definition
|
|
Term
| What kind of data does LTC use |
|
Definition
Address Data
sync data
user bits
(date, reel number etc.) |
|
|
Term
| The address is updated ______ times per second. |

Definition
|
|
Term

Definition
|
|
Term
| What are the advantages of LTC? |
|
Definition
(1)Can be striped/recorded onto tape before and after the audio/video data
(2)Can be read at very high speeds
(3)Can be used for both audio and video editing |
|
|
Term
| What are the disadvantages of LTC? |
|
Definition
(1)Cannot be read at very slow tape speeds or during tape pause
(2)Uses up an audio track of it's own |
|
|
Term
| What frequencies does LTC use? |
|
Definition
LTC uses fundamental frequencies
(e.g. 1kHz and 2kHz between 24 and 30 fps)
to which human hearing is very sensitive and so cross talk between tape tracks (and console channels) is easily heard. |
