Video Input Port (VIP) can be found on devices such as DRA7xx and
|
||||
provides the system interface and the processing capability to
|
||||
connect parallel image-sensor as well as BT.656/1120 capable encoder
|
||||
chip to DRA7x device.
|
||||
|
||||
Each VIP instance supports 2 independently configurable external
|
||||
video input capture slices (Slice 0 and Slice 1) each providing
|
||||
up to two video input ports (Port A and Port B).
