VIP_PAGE_OFFSET Register Map
PAGE_OFFSET
VIP_PAGE_OFFSET Bit Descriptions
Description
Page Offset. This register specifies the offset to the next page of buffer data. If the page
count is 2 or greater, the next frame of data is started at an address of buffer +
PAGE_OFFSET. Up to eight pages (frames) can be accumulated. The address of the
next frame is located at a "Page Offset" address. Note that ancillary data and MSG/
STRM data is not paged. This only applies to video and VBI data. The value in this regis-
ter needs to be 32-byte aligned. (Bits [4:0] are required to be 00000.)

VERT_END
VIP_VERT_START_STOP Bit Description
Description
Reserved. Set to 0.
Vertical End Capture. This register specifies the last line # in a field/frame that is cap-
tured when the subwindow capture function is enabled in non BT.601 modes. In BT.601
interlaced modes, this register determines when the odd field line capture completes. In
601 non-interlaced modes, this register determines when the video capture completes.
See Figure 6-48 "BT.601 Mode Vertical Timing" on page 473 for additional detail.
Reserved. Set to 0.
Vertical Start Capture. This register specifies the first line # in a field/frame that is cap-
tured when the subwindow capture function is enabled in non 601 modes. In BT.601
interlaced modes, this register determines when the odd field video capture starts. In
BT.601 non-interlaced modes, this register determines when the video capture starts.
See Figure 6-48 "BT.601 Mode Vertical Timing" on page 473 for additional detail.
