Table 15.
The incoming YCbCr 4 : 2 : 2 (2 × 12-bit) data stream format could be upsampled into
YCbCr 4 : 4 : 4 (3 × 8-bit) data stream by repeating or linearly interpolating the
chrominance pixels.
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:
Remark: Gamut-related metadata is an HDMI 1.3a feature.
This block works only with YCbCr input format; the filters downsample the Cb and Cr
signals by a factor of 2. A delay is added on the Y channel, which corresponds to the
pipeline delay of the filters, to put the Y channel in phase with the Cb-Cr channel.
TDA19989 is compatible with the following audio features described in the HDMI 1.3
