Input Signal Specifications

1. Horizontal sync signal

• With NTSC, NTSC WIDE, PAL, PAL+, and MNDC, the standard signal is doubled in speed, and a 1/2 cycle,

1/2 width horizontal sync signal (H.SYNC) is input.

• With HD, a signal derived by cutting off the lower part of 3-value sync is input.

• Negative polarity input is used.

2. Vertical sync signal

• V.sync separated by synchronizing separation circuit and not doubled in speed is input as the vertical sync

signal.

• Negative polarity input is used.

• With this TG, the phase relationship between VSYNC and HSYNC is as follows;

(1) NTSC/NTSC WIDE/MNDC

Phase reference

HSYNC

(Double-speed H.sync)
