With the embedded 32-bit RISC
processor NX3320 carries out all the tasks for
enjoying DMB services, from RF IC control to
the video and audio output management and data
service decoding. Effort to add a DMB feature
to mobile terminals therefore can be alleviated
considerably in terms of software as well as
hardware. Even the advanced functionalities,
for example time-shift, live-rewind, and file-playback,
could be easily implemented using the high level
API’s provided.

Mobile Phone
with T-DMB
The block diagram below shows a configuration
of T-DMB enabled mobile phones. With NX3320 and
a RF IC, T-DMB can be enjoyed in the mobile phone.
In the voice call mode MSM can directly manage
the frame buffer in the LCD module as usual since
NX3320 opens the CPU interface to the LCD module.
While watching T-DMB, on the other hand NX3320
updates the frame buffer 30 frames per second
by itself. If a TV encoder is connected to NX3320,
the same DMB video can be played on a TV.

Premium channels in S-DMB can be also available
on the T-DMB phone with NX3320 as illustrated
below.

Convergence
Device with T-DMB
Personal media players (PMPs), portable game
consoles, and telematics terminals are a few
of leading products in rapidly emerging digital
convergence market. NX3320 is able to reinforce
the convergence device with T-DMB feature in
reduced development time.

|
 |
| |
Along with the
AVC based video service, T-DMB would deliver
plenty of useful contents using either BIFS or
MOT, TDC, IP tunneling on the data service channel.
NX3320 is able to extract and decode the BIFS
stream out of the video service. Some of data
service, such as TPEG, SLS, DLS are also supported.

Low End T-DMB
Receiver
Using NX3320 with a few components, such as
RF IC, flash memory, key matrix, LCD module or
panel, and an audio DAC, a low end T-DMB receiver
can be developed.

NX3320이 7mm ×7m, 8MByte SDRAM의 특징을 가지고 있어 휴대폰에
적합한 상품이라면, NX3322과 NX3323은 모듈 이나 포터블 기기에 적합한
제품으로 칩 크기는 8mm ×8mm이며, 탑재된 SDRAM 크기가 8MByte 와
16MByte에 따라 NX3322과 NX3323으로 구분됩니다.
