New HD set-top box decoder (ST)

This article refers to the address: http://

( ) Released a new HD set-top box decoder that integrates both decoding and demodulation functions on a single chip. Designed to meet the needs of major satellite TV carriers worldwide, including DIRECTV, the new STi7111 helps original equipment manufacturers (OEMs) target product design in the mass consumer electronics market, where HDTV is a growing trend. By adding a network interface, Further ensure that the STi7111 can be effectively used in satellite TV and IPTV dual-mode set-top boxes. STi7111's innovative energy-saving technology reduces the final product power consumption and further improves the energy efficiency of consumer electronics.

Based on the decoder engine of the successfully market-proven STi7100 series, the STi7111 supports multiple video standards such as H.264, VC1, MPEG-2, and integrates an independently operated demodulator STV0900 to support DVB-S and DVB. -S2 demodulation circuit. In the past, the TV signal demodulation function was run by an external demodulator, and now the demodulator is integrated into the decoder chip, which saves huge board space and material cost for consumer products. Today most satellite TV broadcasters use DVB-S modulation technology, while DVB-S2 provides the higher bandwidth required for HDTV broadcasts.

STi7111 according to The global environmental strategy is designed and developed to significantly reduce the power consumption of the target set-top box. The power management chip monitors the active state of the STi7111 and dynamically configures the chip according to the system clock to significantly reduce the operating ratio of the chip, minimizing power consumption while maintaining system performance.

The STi7111's processing power is provided by a high-performance 450MHz ST40 CPU with a speed of over 750 DMIPS, capable of driving the most demanding set-top box middleware and graphics applications, while a 32-bit unified memory The interface provides a highly cost-optimized architecture.

HD video is output to the display at up to 1080p resolution via the chip's built-in HDMI 1.3 interface, while the on-chip Ethernet interface makes the STi7111 an ideal home networking solution. The STi7111 also provides a PCI interface to support more industry standard peripherals.

In order to allow customers to better use the STi7111 hardware, And third-party partners also offer a set of development Tools, including tools that support the Linux and OS21 operating systems, STAPI drivers, and adaptation software that supports all major middleware.

The engineering samples of the STi7111 have now been delivered to major customers for testing. All major satellite TV set-top boxes and digital TV all-in-one manufacturers are welcome to request product pricing.
