STMicroelectronics announced today the availability of a new single-chip, high-definition set-top box decoder combining both the demodulation and decoding functions on a single device. The STi7111, which has been designed to meet the requirements of international satellite operators, will allow OEMs to target the high-volume market for consumers moving to high-definition services. By including a network interface, STMicroelectronics has further ensured that the STi7111 can be effectively used in a hybrid Set Top Box (STB), where content is delivered by both a satellite and an IP network.
The STi7111 supports H.264, VC1 and MPEG-2 and includes circuitry to demodulate both DVB-S and DVB-S2 signals based on the STV0900 standalone product. This provides customers with considerable board-space and lower costs as the demodulation function was previously performed by an external device.
In line with STMicroelectronics' global environmental strategy, the STi7111 has been designed to significantly reduce the energy consumption of the target STB. The power management system monitors the activity of the STi7111 and dynamically configures the system clocks to run at radically reduced rates to minimise energy consumption while maintaining system performance.
Processing power for the STi7111 is provided by a high-performance 450MHz ST40 CPU which delivers an excess of 750 DMIPS to drive today’s demanding STB middleware and graphics applications. A 32-bit unified memory interface provides a highly cost-optimised architecture.
“ST’s set-top box solutions are the most widely deployed throughout the world, and we are constantly looking at adding value to the STB industry through highly integrated solutions, bringing radical power reduction while improving system performance and reducing overall system cost,” said Youssef Kamel, director of the Satellite and Terrestrial Operator Business Unit, STMicroelectronics. “The STi7111, through its exceptional level of integration in the most advanced manufacturing process, enables service providers to deploy high-definition programs in large volumes, while offering their subscribers the richest viewing experience."
