TDA19977A; TDA19977B
Triple input HDMI receiver interface with digital processing
8.13 Sync timing measurement
To assist input format recognition, the vertical/horizontal periods and the horizontal pulse
width are measured based on the externally generated MCLK frequency (27 MHz crystal).
This function has an accuracy of 1 LSB = 1
× MCLK period.
8.14 Format measurement timing
The TDA19977A; TDA19977B includes an improved system for accurate recognition of
PC and TV formats. This system measures the parameters of blanking and video active
area.
This function can be useful for example when the TDA19977A; TDA19977B receives PC
format data in HDMI or DVI modes.
8.15 Color space conversion
The color space conversion enables an RGB signal from the HDMI input to be converted
into a YCbCr signal or converting the YCbCr signal from the HDMI input into an RGB
signal. The color space conversion formula is:
(1)
Activation of the color space conversion function, programming of all coefcients and
offsets is done using the I2C-bus.
8.16 4:2:2 downsampling lters
These lters downsample the Cb and Cr signals by a factor of 2. A delay has been added
to the G/Y channel corresponding to the downsample lters pipeline delay to make sure
the Y channel is in phase with the Cb and Cr channels.
Four different lters, from simple cut to ITU-R BT.601 compliant digital, can be selected
using the I2C-bus.
8.17 Range control
The range control function truncates the range of data to remove super-white and
super-black pixels at specied ceiling and oor values.
8.18 Dithering function
The error dispersal rounding (dithering) function can convert the color depth from 30-bit or
36-bit to reduced 30-bit or 24-bit color depth. When dithering is triggered, the
TDA19977A; TDA19977B applies round, truncate or noise-shaping algorithms.
When the error dispersal rounding function is not used, the data coming from the lter is
directly sent to the 4:2:2 formatter. The error dispersal rounding function works only with
the active video signal.
