Release high-definition set-top box ST decoder chip STi7111-decoder chip, set-top boxes - the electronics industry
IC ST Suppliers Semiconductor In a recently released Chip The integration of the two decoding and demodulation functions of a new high-definition set-top box Decoder . To meet the world's major Satellite TV Carriers (including DIRE CT V), the needs of design, new product STi7111 help original equipment manufacturers ( OEM ) Will aim to design high-definition television (HD) for the development trend Public Consumption Electronic Market. By adding a Network Interfaces, ST to further ensure STi7111 can dual-mode satellite and IPTV set-top boxes are effectively applied. STi7111 innovation Energy Technology to reduce power consumption the final product, to further improve the energy efficiency of consumer electronics products.
Based on proven successful STi7100 series decoder engine, STi7111 support H.264 , VC1, M PE G-2 and other video standards, and integration of an independence-based demodulator STV0900, to support DVB-S and DVB-S2 demodulation circuit. Over the past television signal demodulation function is run by an external modem, and now the demodulator integrated decoder chip for the consumer to save a great Board Space and materials costs. Today, most satellite TV Broadcasting Companies use the DVB-S modulation technology, DVB-S2 is able to provide high-definition television's higher bandwidth requirements.
STi7111 according to ST's global environmental strategy development and design, can significantly reduce the power consumption targets set-top boxes. ST's Power supply Management Monitoring the activities of state STi7111 chip, according to dynamically configure the system clock chip to significantly reduce the chip's operating ratio to achieve the product to minimize power consumption while maintaining system performance.
STi7111 processing power is of a high-performance 450MHz ST40 CPU Provided that the micro- Processor Rate of more than 750DMIPS, can drive the most demanding set-top boxes currently middleware and graphics applications, while unified by a 32-bit Memory Interface provides a highly optimized architecture cost.
High-definition video through the chip interface, built-in HDMI1.3 resolution up to 1080p output to the display, while on-chip Ethernet interface to STi7111 an ideal Home Networking Solution. STi7111 also provides a PC I interface to support more industry standards Peripherals .
STMicroelectronics satellite and terrestrial television division director YoussefKamel said, "ST's set-top box solution is the world's most widely used solution, we have been studying the adoption of highly integrated solutions for set-top box industry lead to higher value, significantly lower power consumption, while improving system performance, reduce overall system cost, using the most advanced manufacturing processes to achieve high integration, STi7111 to television providers to large-scale promotion of high-definition TV programs, while allowing television subscribers get the best viewing experience rich. "
To allow customers to make better use of STi7111 hardware, ST and third parties Cooperation Partners also provide a set of development tools, including support for Linux and OS21 Operating system Tools, STAPI drivers and supports all major middleware adapter Software .
STi7111 of Project Sample has been delivered to major customers Test , ST is open to all the major satellite Television Top box and Digital TV One machine Obtained from a single vendor pricing.
I am an expert from China Crafts Suppliers, usually analyzes all kind of industries situation, such as 110cc dirt bike parts , bajaj spare parts.
