Software Structure for an ATSC Digital TV Application
The DLVM-GL module is very similar to
the DLVM-GC module, and in addition to
the above functionality, it provides 8/16-bit
digital video output to interface to a LCD
TV chip that accepts digital video. It also
provides 1 channel of I
Software Structure: These modules use a
software stack as shown in the diagram

complete documentation of the API and
sample code for easy integration with an
analog TV chassis. The Software Kit comes
with a font engine and fonts, which can be
replaced by the user if different fonts are
required. Similarly, the tuner driver can also
be replaced for a different tuner. The
software has gone through extensive
qualification including Dolby certification and
is Sarnoff compliant.
