PROJECT PROFILE
1.TYPE: Application And Device Driver Development
Title DVB-Common Interface
Description
A set of standards has been designed to be used in digital video broadcasting.
These standards include source coding, channel coding, service information and
decoder interfaces. In addition, a conditional access system is used when there
is a need to control access to a broadcast service. It has been decided that the
conditional access system need not be standardized, although a common
scrambling algorithm is provided. A solution is based on a standardized interface
between a module and a host where CA and more generally defined proprietary
functions may be implemented in the module. The communication between
module and host is based on EN50221 specification.
Role
Design, Development, Enhancement, Porting and Debugging, Team leading and

3. co-ordination, Trainer, Hardware tracing.
Responsibilities
 Get the schematics from customer for the base target and examine for any
hardware connection fault and device layout issues in the DVB-CI related
 Circuits and DVB-CI TS routing related circuits.
 Prepare the diagnostics s/w to diagnose the DVB-CI communication and
notify to the customer for any defects in the hardware layout.
 Ported our DVB-CI stack for the current hardware and validated the CAM
communication and DVB-CI TS routing.
 Multi service descrambling design and implementation (which is mandatory
for CI Plus v1.4).
 CI HAL design and implementation to ease the porting work.
 Linux device driver implementation for CAM communication.
 Dedicated on-site support to resolve the Astra and Neotion CAM
descrambling failure issue in GMI-7111 project.
2.TYPE: Application And Device Driver Development
Title DVB-Common Interface Plus
Description
CI+ is a extension of DVBCI. By making use of certificates and a certification
authority, a trusted channel is formed between the CAM and HOST when
scrambled content is being received. In the original CI standard, decrypted
content could be sent over the PCMCIA interface unscrambled. Although more is
applied on controlled content using URI, License and Service Shunning.
Role
Design, Development, Enhancement, Porting and Debugging, Trainer, Hardware
tracing.
Responsibilities
 Complete CI Plus stack implementation (v1.2 and v1.3).
 The major implementations are Content Control, CAM Upgrading Operator
Profile, Low Speed Communication, Application MMI resources and service
shunning feature.
 SMARDTV test cases analysis and testing of CI Plus v1.2 and v1.3 stack.
 DTV Labs official test, production credential integration and stack validation
 CI Plus Interim License agreement specification analysis and
implementation. The major implementations are URI, Controlled Content
recording & output routing and other security solutions (secure loader, RAM
content protection, debugging port protection).
 Factory process design and implementation to burn production credential in
STB flash.
 Fips-Openssl cross compilation and integration in DVB application for CI+
cryptographic operations.

4.  Test case document derivation and validation.
 Inter-module communication to meet specification requirements and
application level integration.
 Customer communication to regarding CI Plus certification process and
clarify the technical queries.
3.TYPE: Application And Device Driver Development
Title Conditional Access System – CAS
Description
A conditional access system comprises a combination of scrambling and
encryption to prevent unauthorized reception. Encryption is the process of
protecting the secret key that are transmitted with a scrambled signal to enable
descrambler to work. This scrambler key is called as CW must of course be sent
to the receiver in the encrypted form as an ECM. The CA subsystem in the
receiver will decrypt the CW only when authority sent to receiver in the form of
EMM. This layered approach is fundamental to all proprietary CA system in use
today.
 Nagra Vision
 CryptoGuard
 Simulcrypt Head-End System.
Role
Design, Development, Enhancement, Porting and Debugging, Trainer, Hardware
tracing.
Responsibilities
 Nagra Vision and CrytptoGuard CAK document analysis and integration.
 Implementation of smart card and descrambler device driver to user
application.
 Fulfilled the cryptogurad requirements that are unique STB ID generation,
encrypting and decrypting the PVR contents using the AES-128 CBC
algorithm with chip specific.
 Solved the problems in the smartcard driver code during Nagra electrical
test.
 Dedicated and timely support to implement the Nagra secure loader.
 Implemented PC based (Ubuntu OS) ECM (Entitlement Control Generator)
and EMMG (Entitlement Management Generator) which communicates with
scrambler and multiplexer using the TCP/IP protocol for Simulcrypt Head-
end.
