Tata Elxsi has over a half-decade of expertise in technology
development and deployment of MPEG technologies in products.
We have developed MPEG1/2/4 video encoders and decoders
supporting various profiles & levels and resoutions(QCIF,
CIF, 4CIF, QVGA, VGA) and supporting various output formats
like NTSC and PAL, for a wide variety of applications
including DVD authoring, Internet streaming, Teleconferencing,
Digital Video Broadcast and Mobile multimedia.
Our technological depth is reflected in development of
a few original algorithms for highest quality video processing
in real-time, such as:
|
|
Adaptive search motion estimation |
 |
Scene change detection |
|
Sliding window rate control |
|
Macro-block centric VOP processing |
These efficient algorithms enable efficient video encoding
and high quality video delivery to end-users. Unique error
resilience schemes protect against unreliable transport
mechanisms.
Tata Elxsi has implemented most video conferencing standards
including H.320, H.323, H.324 and SIP protocols over DSP/RISC
platforms in products. Examples include:
|
|
H.323 implementation
on SA110 based system for a Conference over IP application. |
|
H.320 protocol implementation
on ADSP218x & 2106x based system for a DVI (Digital
Video Intercom) application. |
Tata Elxsi expertise includes algorithm development
and optimization in C and assembly over DSP platforms
to support real time encoding/decoding as per application
demands.
