Description

Toshiba has designed two application­specific modules based on the
TC90407XBG digital TV SoC that can
reduce design-to-production time:

– DLVM-GC
– DLVM-GL
The DLVM-GC module is designed for

digital CRT TV applications and the DLVM­GL module is designed for LCD TV
applications. Both modules decode digital
transmission content and provide analog or
digital output to existing backend
processors in TV systems that decode
analog transmissions for display. The
DLVM-GC module can be plugged into an
existing analog CRT chassis or mother­board through a connector. Similarly, the
DLVM-GL module can be plugged into an

existing LCD TV backend processor system
that decodes analog transmission for display.

Features

Hardware Structure: The block diagram of
the DLVM-GC module is based on the
Toshiba TC90407XBG digital TV SoC. The
digital tuner IF output is connected to the
VSB demodulator input of the TC90407XBG
chip on the module. The DLVM-GC can
decode HD or SD stream and provide analog
output in 480i format (CVBS, S-Video or
Component Video) for digital CRTTV
applications. It can also provide component
analog output in 480p/720p/1080i format.
This module generates analog stereo audio
output and digital audio output (SPDIF). The
DLVM-GC module design can also be used
for digital converter box applications.

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 I2S 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 middle­ware, 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 I2C 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.
