As a response to the expanding market for digital TV services requiring the DVB-MHP (Digital Video Broadcast - Multimedia Home Platform) middleware, STMicroelectronics developed a new hardware and software reference design that targets this specific market.

The reference design is comprised of the company's STi5517 MPEG-2 decoder, a choice of satellite or terrestrial demodulators, a comprehensive suite of software drivers, and a fully-certified DVB-MHP software stack which includes a Java Virtual Machine (JVM). The hardware elements are packaged on a two-layer PCB.

On a single chip, the STi5517 combines an ST20 CPU, MPEG-2 video and audio decoders, transport interfaces, advanced security, and many of the peripherals required by today's STBs.

"The key component of the new reference design that ensures our customers' products are brought to market in the shortest possible time is the pre-integrated, fully-certified DVB-MHP software stack," said Christos Lagomichos, GM of STMicro's STB Division. "The availability of this software gives set-top box manufacturers the opportunity to obtain all the core hardware and software components for their products from us [STMicro], saving them time and money from both the administrative and engineering perspectives."

Meeting the requirements of all services currently using MHP by being compliant with Enhanced and Interactive Profiles of DVB-MHP 1.0.2, the company's software stack also includes code to implement the more recently published DVB-MHP 1.0.3 specification. The stack also features a customizable user interface that manufacturers can adapt to reflect their brand.

According to Lagomichos, the availability of interchangeable front-end modules ensures that their reference design can be applied to all DVB-MHP services with minimal change to the underlying hardware. "The software architecture also reflects this modular structure, so customers can address different markets with minimal engineering effort," he added.
