6.11.1 Source Input Blanking
The vertical and horizontal blanking requirements for both input ports are defined in Table 3, except when using a 120 Hz source. In this case, please use the source input blanking timing found in Table 4. Refer to the video timing parameter definitions listed in视频时序参数定义. Also, see Figure 7 for Parallel I/F Frame Timing.
