5. VIDEO OPERATIONAL TIMING
The KS0119 can operate in either slave or master mode. In slave mode, the chip uses two external input signals,
active video (AV) and vertical blank (VBLK), to synchronize the internal operation. In master mode, however, the
chip outputs these two signals. The chip generates two additional signals: Memory Transfer Request (MRQST) and
field two indicator (F2), which can be used to simplify the interface to an external frame buffer controller. Figure 9
shows the timing waveform for the NTSC output mode.
Figure 9. NTSC Output Timing
In Master mode, the timing shown in Figure 10 is maintained among AV, VBLK, and F2, where n is the leading pixel
number (see Figure 12 for more detail). In Slave mode, the two inputs AV and VBLK must meet the timing
requirement as shown in Figure 11 in order for the Encoder to obtain the correct field information.
