The VIP receives data and stores it into system memory.
The VIP input modes with associated data types are shown
in Table 6-74. VIP 2.0 is the VESA VIP 2.0 Level I (8-bit)
standard or the VESA VIP 2.0 Level II (16-bit) standard.
VIP 1.1 is the VESA (8-bit) standard in which only a single
video stream is supported and the TASK bit is used to dis-
tinguish between video and VBI data. MSG is the 8-bit
Message Passing mode, and STRM, the Data Streaming
mode, provides support for generic 8-bit data streaming.
MSG and STRM modes are proprietary data transfer for-
mats and are not defined in the VESA VIP specification.
Table 6-74 defines the data types received in each mode.
VIP 2.0 supports nine different data types. This allows
reception of two separate video streams (Task A and B)
plus ancillary data. VIP 1.1 mode supports five data types
(Task A only). One data type is associated with the MSG
and STRM modes.
