SD Video Mode
The interleaved data (YUV) is captured from the dv_data[9:0] input, also called
Channel A. The dv_d_data, also called Channel B, is not used in the SD mode.
HD Mode
The Y data is expected on dv_d_data[9:0] (Channel B) and U/V data is expected on
dv_data[9:0] (Channel A).
RAW MODE
In RAW mode the data can be captured from Channel A or B.
A separate signal, dv_valid, is provided to validate all incoming data. The relationship
between dv_valid and data, with reference to clock, is shown in
The Test Pattern Generator produces a video stream with a pixel frequency of half the
VIP input clock e.g., the 27 MHz encoder clock by programming the clock selection
block accordingly.
The sync generation is NTSC-like, with 525 lines per frame and 858 pixels per line.
The active video range is 720x462 bordered by a white frame.
