The TDA9984A can be synchronized with external input signals HSYNC and VSYNC or
with extraction of the sync information from embedded sync codes (SAV/EAV) inside the
video.
This block can extract the synchronization signals HREF, VREF and FREF from SAV and
EAV in case of embedded synchronization in the data stream.
Synchronization signals can be embedded in YCbCr 4 : 2 : 2 ITU656 (up to 1
and semi-planar (up to 2
TDA9984A contains a Data Enable (DE) generator. This circuit generates an internal DE
signal for a system which does not provide one. The DE generator is controlled via the
I
Due to the flexible video input formatter, the TDA9984A can accept a large range of inputs
formats. This flexibility allows the TDA9984A to be compatible with the maximum number
of MPEG decoders. Moreover, these input formats may be changed in many ways (space
color converter, upsampler and scaler) to be transmitted across the HDMI link.
