Available as part of the Aurora DVB complete middleware solution or as an OAD plug-in, a Callisto OAD update enables manufacturers to easily enhance products and fix field issues after deployment.  Critical market windows can also be maintained by providing manufacturers with the option to release enhanced functionality after the product has been released.

A standards-based approach for extensive market coverage

Callisto is fully compliant with ETSI SSU and Enhanced SSU standards as well as the UK D-Book, making it the OAD mechanism of choice for deployment in any country supporting these standards.  Callisto automatically configures itself to the correct OAD protocol on detecting the appropriate network and will switch automatically depending on the location of the device.  The DSM-CC data and object carousel enable seamless upgrades to be carried out whether the device is still in the factory or in-situ in the field, providing a reliable, stable and robust service which manufacturers can trust.

Callisto also provides a range of options for how the upgrade will take place.  Forced downloads can be set to take place at specified dates and times or user interactive downloads can be activated via on-screen messages sent directly to the viewer.

Easy integration of new standards and functionality

The scalable and modular architecture of Cabot products enables Callisto to be easily added to the Eclipse DVB core without any additional integration effort.  Callisto is fully portable and includes many features which enable it to be integrated with other DVB cores with minimal time and effort.  Its easy integration features include:

• A software development kit, utilising C++ programming language

• A well documented, standardised Application Programme Interface (API)

• An adaptation layer called CHIL (Cabot High-Level Interface Layer)

• Market-leading porting guides and support services

The SEA Security Manager

The Security, Encryption and Authentication (SEA) Manager is an optional feature for Callisto which provides complete software security for receivers deployed in the field.  As there is no default security provided in the OAD standards currently deployed, unprotected receivers in the field are exposed to potential mass erroneous field upgrades, leaving their manufacturers liable to the resulting cost implications.  Using SEA, manufacturers can protect their receivers from malicious, corrupted and misdirected over the air upgrades or improper upgrades via hardware interfaces.

The SEA includes a PC toolkit which enables manufacturers to digitally sign software upgrades using public key cryptography.  It works by embedding key pairs in the receiver so that only authenticated and authorised upgrades will be re-flashed by the receiver.  In addition, to protect from possible corruption over the network, the SEA PC toolkit generates a specialised and rigorous checksum to be verified by the receiver before upgrade acceptance.
