The services provided by Sasken under this layer are targeted at application-specific components/ middleware. These components depend upon the application segment for which chipset/ platform is targeted. These components mainly include media engines and communication engines, which form an integral part of any product.

Communication Engines : The services include, development, porting, optimization and testing of various communication engines, which include Base-Band algorithms, MAC, Wireless/ Wireline protocol stacks, as well as Datacom and Networking layers for wireless and wireline communication standards.

Sasken has the expertise to work with technologies such as:

• WLAN, WiMAX [802.11 a/bg, 802.16]
• DVB-H
• GSM/GPRS, WCDMA
• Bluetooth, UWB
• ADSL, VDSL
• Generic Networking Protocols [TCP/IP, UpNP, RTP/RTCP, MTP]

Media Engines : The services comprise development, porting, optimization, integration and testing. Sasken provides services for audio, video, space & image codecs based on open standards as well as third party proprietary standards.

Sasken's multimedia expertise covers a wide range of encoder, decoder and codec implementations for speech, audio, video and image processing on embedded DSP and RISC platforms.

Systems Integration Expertise
In addition to delivering codecs, Sasken has expertise in Systems integration, on target platforms and has developed the UI/MMI layer.

The illustration given below shows the typical Multimedia AV system, which depicts codecs/media engines having several API layers for interaction with Application layer, Hardware layer and peripherals.

Sasken believes that a critical challenge is in designing codecs for easy/rapid integration on a given framework. And, having had the experience of working through these challenges, Sasken address the concerns while authoring the codecs requirements and API specifications.
