TASK_B_VBI_DATA_ODD_BASE_VBI_START (for 601 type modes)
Description
VBI End. This register is redefined in BT.601 mode. In BT.601 type input modes, timing
is derived from the external HSYNC and VSYNC inputs. This value specifies what line
the VBI data ends in each field/frame. The end of VBI data is reached when the number
of lines from the falling edge of VSYNC equals this value. See Figure 6-48 "BT.601 Mode
Vertical Timing" on page 473 for additional detail.
Description
Reserved.
Description
Task B VBI Odd Base Address. This register specifies the base address in graphics
memory where VBI data for odd fields is stored. Changes to this register take effect at
the beginning of the next field. This value must be 32-byte aligned. (Bits [4:0] are
required to be 00000.)
Note:
VBI Start. This register is redefined in BT.601 mode. In BT.601 type input modes, timing
is derived from the external HSYNC and VSYNC inputs. This value specifies what line
the VBI data starts in each field/frame. The start of VBI data begins when the number of
lines from the leading edge of VSYNC equals this value. See Figure 6-48 "BT.601 Mode
Vertical Timing" on page 473 for additional detail.
This register is double buffered. When a new value is written to this register, the
new value is placed in a special pending register, and the Base Register Not
Updated bit (VIP Memory Offset 08h[16]) is set to 1. The VBI Odd Base Address
register is not updated at this point. When the first data of the next field is cap-
tured, the pending values of all base registers are written to the appropriate base
registers, and the VBI Base Register Not Updated bit is cleared.
