Abstract Since 1996, the Digital Television (DTV) market has been exponentially growing. Based on widely accepted MPEG and DVB standards, the digital television offers a higher image quality as well as an unlimited number of interactive services.
Canal+ Technologies provides a complete end-to-end solution for Digital Television operators, from the central broadcast centers to the set-top boxes at home. The DTV broadcast center systems have availability, reliability and load constraints which require a robust implementation. For this reason, the server-side components of the Canal+ Technologies software have been developed in Ada.
This paper explains the architecture of a Digital Television system and how Ada is used inside this system. It also describes how this system is currently reengineered from a proprietary Ada 83 / OpenVMS implementation using the DEC Ada compiler to an Ada 95 multi-platform implementation using the GNAT compiler.
