High-Definition Video Processing Subsystem (HDVPSS)
The Luma representing Active Video is stored in a set of Planar Buffers. The CbCr Chroma Pairs are
stored in a set of Planar Buffers.
1.2.8.2.4 Input Data Interface
This section describes how the data (luma and chroma data for YUV422 format capture & R,G and B data
for RGB888 format capture) is muxed for the interface modes described below.
1.2.8.2.4.1 8b Interface Mode
In 8b data interface mode, the input pixels are multiplexed according to
. The Chroma Format
is 4:2:2. Sites with Cb/Cr pixels are known as Chroma sites. Those sites with Y pixels are known as Luma
sites.

1.2.8.2.4.2 16b Interface Mode
In 16b interface mode, Luma is on 8 bits of the data bus and Cb/Cr chroma pixels alternate on the other 8
bits of the data bus as shown in
