The new platform is a highly integrated set-top box platform tailored to the Brazilian market, supporting Brazil's unique digital TV and middleware standards, enabling device manufacturers to develop affordable, compact displays using advanced system-on-chip (SoC) integration capabilities. solution.
Herve Mathieu, Director of STB and Gateway Group, STMicroelectronics' Unified Platform Products Division, said: "STMicroelectronics has a wealth of analog TV digitization experience in South America and around the world, and continues to lead in this field. Our one-stop platform includes Tailor-made hardware and software for the Brazilian market, providing an affordable, fully compliant set-top box solution for the local market, bringing richer and more advanced TV services to viewers across Brazil."
A major customer active in the analog TV digital market in South America has developed a set-top box based on the platform.
The platform integrates the latest STMicroelectronics STiH206 set-top box system chip with built-in EiTV's Brazilian GINGA (Java + NCL) middleware and MaxLinear MXL683 tuner/demodulator chip supporting Brazil's unique ISDB-T terrestrial digital TV broadcasting standard. . GINGA is the open television middleware standard implemented by the Brazilian government to promote the digitization of analog TV.
As a member of the STMicroelectronics Liège digital set-top box system chip family, STiH206 has been widely used in Brazil's national paid set-top box market, as well as digital TV projects led by neighboring countries such as Venezuela. The STiH206 is packaged in a BGA 23x23mm package that integrates ST's market-proven ST40 application processor with fast DDR3 memory and L2 cache for efficient high-speed execution of applications and middleware. Excellent graphics performance makes this system chip ideal for supporting Brazilian proprietary GINGA middleware.
The STiH206 integrates ST's latest video decoders and video post-processors to support MPEG2, H264, VC-1 and AVS HD video standards. The system chip also supports a variety of peripheral interfaces, including USB2.0, SD-MMC/SDIO and Ethernet, to flexibly support a variety of peripherals, such as USB flash drives, mobile hard drives or home network controllers (such as MoCA) ® or Wi-Fi controller).
EiTV middleware is a full-featured middleware that fully implements the ISDB-T receiver middleware standard in the GINGA specification. By porting the middleware to the STiH206 chip, STMicroelectronics and EiTV have collaborated to develop a platform that meets the digital TV requirements of the Brazilian government. Equipment manufacturers choose the new set-top box products designed by the platform to ensure compliance with the technical standards issued by the Brazilian Technical Standards Association (ABNT).
The MaxLinear MXL683 tuner/demodulator receiver system ensures that the set-top box end product has excellent ISDB-T broadcast signal reception quality and significantly improves the immunity against RF emissions from 4G LTE smartphones. The problem of multi-channel attenuation and co-channel interference is In the continuing Latin American country, the receiving system showed excellent robustness.
