The MPEG-TS closed caption inserter core
is a drop-in module for insertion of
DTV-708 closed caption into payload of
MPEG video elementary stream. The
MPEG-TS Closed caption inserter core
interprets SMPTE-334 Caption data packet
and insert the caption into the payload
of the Video elementary stream.
Moreover, The MPEG-TS Closed caption
inserter core can insert ATSC PSIP tables
with dedicated Caption service descriptor
and others "on demand"
descriptors.
The output rate of the stream is
slightly increased to allow caption
insertion and PSIP generation. PCR
restamping is done to make the output
consistent.
A 8-bit CPU interface is available for
core control. By default the core can
start up without CPU initialization.
