STMicroelectronics has developed a new single-chip high-definition set-top box (STB) decoder combining both the demodulation and decoding functions on a single device. The STi7111, which has been designed to meet the requirements of major satellite operators worldwide, will allow OEMs to target the high-volume market for consumers moving to high-definition services. By including a network interface, the STi7111 can be effectively used in a hybrid STB, where content is delivered by both a satellite and an IP network. Innovative power-saving techniques further benefit consumers by reducing the energy requirements for the endproduct.
Built upon the proven decoding engine used in the successful STi7100 series of devices, the STi7111 supports H.264, VC1, MPEG-2 and numerous other video standards and includes circuitry to demodulate both DVB-S and DVB-S2 signals based on the STV0900 standalone product. This provides customers with a considerable board-space and cost saving as the demodulation function has previously been performed by an external device. DVB-S modulation is used by the majority of today’s satellite broadcasters while DVB-S2 provides the higher bandwidth required by high-definition programming.
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 is provided by a high-performance 450 MHz ST40 CPU which delivers in excess of 750 DMIPS to drive demanding STB middleware and graphics applications, while a 32-bit unified memory interface provides a highly cost-optimised architecture. High-definition video is output through the embedded HDMI 1.3 interface at up to 1080p resolution and a PCI interface is provided in order to support a wide range of industry-standard peripherals.
