8.1.1 Internal assignment
8.1 Video processing
The TDA9984A is designed to convert digital data (video and audio) provided by a
Set-Top Box or DVD into an HDMI output, which could be used in TV with HDMI or DVI
input.
The TDA9984A is able to output HDMI with the formats:
The video data input formats are:
It can also handle audio formats:
The TDA9984A has three video input ports VPA[7:0], VPB[7:0] and VPC[7:0] and can
handle any of the following video input modes:
The TDA9984A can be set to latch data at either the rising or the falling edge.
The aim of the video input processor is to map internally the incoming data to the
corresponding mode, which can be handled by the video processing. The device expects
to have a big endian digital stream at its input. The internal signal name VP[23:0] is
assigned depending on the input mode as defined in
Fig 3.
