7.3 Input and output video format
7.4 Upsampler
7.5 Color space converter
7.6 Gamut-related metadata
Due to the flexible video input formatter, the TDA9989 can accept a large range of input
formats. This flexibility allows the TDA9989 to be compatible with the maximum possible
number of MPEG decoders. Moreover, these input formats may be changed in many ways
(color space converter, upsampler, downsampler) before it is transmitted across the HDMI
link.

The color space converter is used to convert input video data from one type to another
color space (e.g. RGB to YCbCr and YCbCr to RGB). This block can be bypassed and
each coefficient is programmable via the I
Gamut-related metadata is an enhanced colorimetry beyond the default standard with
higher definition colorimetries. Profile P0 is supported, which means that only one packet
per video field is sent. Color gamut boundary data are defined the standards:
