For CVI and CVO IP cores, the BT656 and BT1120 formats use time reference signal (TRS) codes in the
video data to mark the places where synchronization information is inserted in the data.
Figure 2-4: Time Reference Signal Format
The TRS codes are made up of values that are not present in the video portion of the data, and they take
the format shown in the figure below.
