Product Brief
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
2
S digital output.
Software Structure: These modules use a
software stack as shown in the diagram
below. The firmware and device drivers
are ported for a Linux
®
operating system.
Toshiba’s industry-proven ATSC middle-
ware, driver and application adaptation
layer software along with sample
application code are available for quick
product deployment. The software stack

can upgrade an existing NTSC LCD/CRT
TV chassis to be ATSC compliant. The
interface between analog TV and an ATSC
module, over a UART or I
2
C bus, can be
easily customized by the system integrator
or ODM. The Software Kit also comes with
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.
