Teatro-2.0

A fitted solution for your broadcast STB

teatro 20 model

Teatro-2.0 represents the baseline of iWedia’s turnkey software solutions targeting broadcast only DVB receivers. It is built around Comedia 2.0 DVB software stack closely merged with Maestro - iWedia’s proprietary toolkit for application and user interface design. Teatro-2.0 can be easily ported on a variety of hardware platforms and may support a variety of options (MHEG-5, CI Plus host software, PVR).
Teatro-2.0 is highly optimized to cope with limited resources terminals and is hence the ideal choice for low-end and mid-end devices targeting emerging markets. As of today it has been deployed in millions of units and field proven in more than 20 DVB countries.

No platform-related limitation
Suitable for UIs in standard (SD) and high definition (HD) resolutions
A number of components supported: label, list, image, etc.

Maestro Generator:

Translation tool that transforms the application description (XML format) into a binary format ready for downflashing the device
Binary compression support for smaller memory footprint

Maestro Player:

An application engine that executes and renders the applications on the target device
Designed to be:
- The smallest possible
- The fastest possible

Architecture overview

The Teatro-2 software architecture allows for a fast product development through:

Easy porting process on the target platform by the virtue of the Comedia Hardware Abstraction Layer (CHAL)
Easy customization of end-user applications with the help of the Maestro toolkit. The Maestro plug-ins expose Comedia features to Maestro applications at an abstraction level keeping the applications as simple as possible
Easy extension of the framework thanks to the modular approach based on software components
