7.2 Video Input Processor
Remark: TM5250 software image processing stages and encoders/decoders
typically use semi-planar or planar 4:2:0 or 4:2:2 formats as input and output.
The Video Input Processor (VIP) handles incoming digital video and processes it for
use by other components of the PNX17xx Series. VIP provides 10-bit accurate
processing. The VIP provides the following functions:
1. VIP output of RGB is mutually exclusive with horizontal scaling
2. Shown are the 2D engine frame buffer formats where drawing, RasterOps and

alpha-blending of surfaces can be accelerated. Additionally, the 2D Drawing
Engine host port supports 1 bpp monochrome font/pattern data, and 4 and 8-bit
alpha only data for host-initiated anti-aliased drawing.
Receives 10-bit YUV4:2:2 like digital video format from the video port. The data is
dithered down to in-memory 8-bit data format. The YUV4:2:2 data stream
typically comes from devices such as the SAA 711x, which digitize PAL or NTSC
analog video. The input data can be other than YUV, like YCrCb as long as it
follows the YUV 4:2:2 video format.
Stores video data inside the video acquisition window in system memory in any
of the native pixel formats indicated in
rounding to convert the10-bit input to the selected format.
Provides an internal Test Pattern Generator with NTSC, PAL, and variable format
support.
