7.3 Input and output video format
TDA19989 can be synchronized with extraction of the sync information from embedded
sync (SAV/EAV) codes inside the video stream or with external HSYNC/VSYNC inputs.
Synchronization signals can be extracted from Start Active Video (SAV) and End Active
Video (EAV) in case of embedded synchronization in the data stream.
Synchronization signals can be embedded in YCbCr 4 : 2 : 2 ITU656 (up to 1 × 12-bit) and
YCbCr 4 : 2 : 2 semi-planar (up to 2 × 12-bit).
TDA19989 contains a Data Enable (DE) generator; this can generate an internal DE
signal for a system which does not provide one.
Due to the flexible video input formatter, TDA19989 can accept a large range of input
formats. This flexibility allows TDA19989 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.
