8.4 Input and output video format
8.5 Upsampler
The TDA9983B can be synchronized with Hsync/Vsync external inputs or with extraction
of the sync information from embedded sync (SAV/EAV) codes inside the video stream.
This block can extract the synchronization signals Href, Vref and Fref 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 RGB, YC

The TDA9983B 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, the TDA9983B can accept a large range of input
formats. This flexibility allows the TDA9983B 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 and scaler) to be transmitted across the
HDMI link.
