The external reference or master clock drives the Sync Gen block. The reference
choice is user configured for 525 (NTSC) or 625 (PAL) line rates. The standard
definition output feeds horizontal and vertical sync to the internal Test Signal
Generator.
The HD Tri Level Sync Gen block is further user configured in BrightEye PC or
Mac to one of four HD formats (
1080i, 1080p, 720p, or 1080sF). The Tri Level
Sync output frame rate can be selected from two choices in BrightEye PC or Mac,
23.98/50/59.94, the most commonly used, and 24/30/60, a frame rate reserved for
use with special applications such as film.
The module will apply the selected Tri Level Sync frame rates to specific formats
and line rates as shown in the table below.
