Multimedia
SoC Technology (MST) |
| |
Multimedia
Emulation Platform (MMP-EMU):
This is a hardware emulation platform that provides
a comprehensive list of video CODEC IP, including
H.264 high profile decoder. It is also serves as
a flexible SoC design platform to support multi-CODEC
solution that can target for customer's specific
requirements.
H.264
High Profile Video Decoder SoC Technology:
This is aimed to provide FPGA and Silicon proven
H.264 High Profile Decoder IP supporting 1080p resolution
video applications. Both FPGA and Silicon IPs would
be verified on the pre-SoC Multimedia Emulation
Platform and Multimedia SoC Test Platform respectively.

There
are a few core technologies which are common across
a few of the key technology initiative areas mentioned
above.
Voice/Audio/Video
CODEC: Support voice, audio and video CODEC
on various popular processors, including TI and
Pixelwork DSP, Intel xScale, ARM and MIPS for various
applications, such as Set Top Box, surveillance,
mobile TV, videophone, portable media player, etc.
Voice
CODEC: AMR-NB, AMR-WB ,
G.711+App-1, 2, G.729A/B, DTMF, CPT
Audio CODEC: HE-AAC v1 & v2, AAC-LC, BSAC, MP3
Video CODEC: H.264 BP, MP and HP, MPEG-4 SP and
ASP
Image
Signal Processing: Built by its experience
on TI DM320 multimedia processor, ASTRI can port
the ISP experience to support a wide range of work,
ranging from driver implementation (e.g., CMOS/CCD
sensor registers tuning and raw data retrieval)
to user-level function implementation (e.g., AE/AWB/AF
algorithms development), and to image quality tuning
for a selected sensor to optimize the performance.
Embedded
P2P Media Distribution: This technology
is developed to combine the power of P2P content
distribution with the unique advantages of embedded
devices to provide an efficient and secure platform
for content distribution. Its application expands
beyond one-to-one streaming in order to support
much higher volume of users watching the content
at the same time through the capability of efficient
many-to-many streaming. It currently supports both
live streaming and VoD function, and provides the
failover protection and network/channel recovery
mechanism via the distributed, coordinated and embedded
platform.
Cache
Facilitated Media Delivery: This technology
offers Internet-based CDN capability by enhancing
the performance of media delivery over the Internet,
resulting in reduced bandwidth consumption and speedy
delivery time. Offering high quality of video over
IP network is strongly growing and highly demanded.
However due to high bandwidth dependency, viewer's
experience to enjoy the content is easily affected
by the network's traffic condition. Usually high
quality of video is delivered via well-engineered
and controlled "Intranet-based" CDN. Video
over Internet has been considered a killer application
for years from both economic and easiness-to-deploy
stand point. A major roadblock of this application
getting full-blown acceptance is the taxing of the
traffic load on the core and access network infra-structure.
This cache-based media delivery mechanism with HTML-based
delivery technology not only eases the traffic load
but also provides flexibility and an open architecture
to the 3rd party ICP and VAS service providers.
With this architecture, this technology is also
easy to adapt/integrate with other delivery technologies,
like Peer-to-Peer.
SIP
Development Platform: The SIP Development
Platform offers a complete solution to build VoIP
client applications. It offers two levels of APIs,
at the SIP Stack's level and the User Agent's level,
for application development on the Linux platform.
The typical call features enabled by this platform
include Proxy Numeric Call, Direct IP Call, Call
Hold, Call Waiting, Call Transfer, and Client-Based
Call Forward. The platform is the perfect suite
for rapid prototyping and short development cycle
of VoIP products.
Wi-Fi/GSM
Call Handoff: This module initially allows
an on-going Wi-Fi/GSM bi-directional voice session
conducted over IP (VoIP) to be transitioned to a
circuit-switched-based transport (i.e., Wi-Fi to
GSM and roaming back). The technology will be further
extended for multi-modal communication devices supporting
multiple network interfaces. One of them can communicate
with the IP domain and the other can interact with
the PSTN domain. The IP domain can be conducted
over Wi-Fi, Ethernet, or 3G/IMS whereas the PSTN
domain can be conventional cellular (GSM or CDMA),
fixed-line analog or ISDN telephony, or DECT-based
or proprietary RF wireless telephony.
Real-Time
Surveillance (RTS): This field proven platform
technology has been used at international airports
as an integral part of the real time surveillance
system. The heart of this platform is a real time
H.264 encoder on a DSP.
