In parts of the world, broadcasting through terrestrial towers or satellites is the primary method for transmitting TV signals. SiTune uniquely supports the TV and Set Top Box markets of these regions by offering an innovative CONCURRENT satellite AND terrestrial tuner that can both work simultaneously. SiTune’s concurrent tuner is the “ultimate radio” because its unique multi-tuner integration places terrestrial and satellite tuners on one die effectively cutting cost by 50%, while its novel design to solve hard interference problems leads the way to an unrivaled multi-channel experience.

SiTune concurrent tuners represent a unique, high-performance satellite/terrestrial radios that are capable of simultaneously receiving up to 6 channels of terrestrial and satellite channels and by providing two tuners on one die, they significantly reduce BOM cost and TV module sizes by at least 50%.

1T/1S

Being first in its class, SiTune’s family of 1T/1S products are highly integrated ICs that incorporate one satellite tuner and one terrestrial/cable tuner on the same die. SiTune’s 1T/1S products support ALL TV STANDARDS with the satellite tuner supporting ALL SATELLITE STANDARDS including the newly announced ISDB-S3 standard in Japan. Each device’s terrestrial/cable tuner covers the 50MHz to 1GHz band, while the satellite tuner covers the 950MHz to 2150/3224MHz range. 1T/1S devices have one LOW-IF output for the terrestrial/cable tuner and one zero-IF output for the satellite tuner. Two channels working together use only 1W of power, which represents a considerable advantage to system designers coping with PCB power dissipation. SiTune’s LOW POWER RF CMOS technology is the key to all of this innovation.

The STN6528 is the industry’s first tuner to support the new Advanced Wide Band Digital Satellite Broadcasting Standard ISDB-S3 (Integrated Services Digital Broadcasting for Satellite, 3rdgeneration, ARIB STD-B44) used to broadcast 8K Super Hi-VISION digital television (TV) via satellite.

In addition to supporting Japan’s new 8K TV satellite standard, the STN6528 is 2 tuners in one and supports the traditional ISDB-T / J.83 QAM terrestrial / cable service and ISDB-S BS / CS digital Full HD and 4K satellite broadcasts as well.  SiTune is the only company to support both satellite and terrestrial / cable RF inputs while CONCURRENTLY tuning both signals and providing both satellite AND terrestrial / cable outputs at the same time.

The STN6528 receives one satellite signal in the 950-3224MHz spectrum AND one terrestrial / cable signal in the UHF/VHF spectrum from 44 to 1002MHz. The STN6528 provides a low power consumption solution as well as a low bill of material (BOM) footprint for the Japanese television and Blu-ray recorder market, enabling the smallest possible television tuner modules capable of supporting 2 (1T/1S), 4 (2T/2S) or 6 (3T/3S) channel television reception.

Devices are evolving with an ever-increasing ability to communicate directly with the World Wide Web and with one another. Applications such as home automation, healthcare, emergency response, intelligent shopping, and smart product management are or will be endowed with sensors, actuators, and transceivers and have the ability to make decisions based on information those devices receive from other devices. All the “things” we deal with on a daily basis will connect together to further enable an easier, more productive life. Such applications will require schemes that enable MANY devices to connect to networks in a reliable efficient way, however, when numerous and various devices attempt to access common wireless channels, increasing contention and access delay will be a challenge as the number of devices goes up. As more devices attempt to access the same wireless band, the greater the amount of contention, which in turn may result in higher connection failure rates. This scenario worsens especially when devices use popular wireless bands such as the 2.4 GHz of Industrial, Scientific and Medical Radio Bands shared by many standards such as IEEE 802.15.4 and IEEE 802.11. Consequently, a need exists to optimize the management of this popular but congested spectrum more effectively in order to maximize channel distribution among an increasing number of devices while also finding ways to reduce contention issues.
Our patent pending IoT solution offers an effective answer to contention issues due to its many key features:

  • Cutting-Edge: Our solution utilizes SiTune’s latest radio technology which achieves unprecedented performance and functionality in capturing wireless signals over a shared wireless spectrum. Alongside patent pending access algorithms, our solution attacks contention issues through a novel cutting-edge approach.
  • More Connections: By allowing more devices to connect concurrently, our solution makes it possible to build larger networks with a greater number of nodes while simultaneously achieving reduced access delays and higher network performance.
  • Compact: With our patented level of integration and wireless radio sophistication, the end product is compact and efficient.
  • Inexpensive: The end product attains a supreme level of integration, resulting in a highly cost-effective solution due to significantly reduced BOM requirements..
