Entropic and Silicon Labs have rolled out a reference design that claims to transform how consumers connect their TVs to the Internet through a robust single-cable connection for both TV and broadband entertainment. The reference design marries expertise in Multimedia over Coax Alliance (MoCA) home networking from Entropic and silicon tuners from Silicon Labs to bring broadband directly to the TV, via a single coaxial cable in the home, the companies indicated.

The design leverages Entropic's EN258x solution, a MoCA 1.1-based chip offering 275Mb/s PHY and 175Mb/s MAC throughput that can be upgraded to Entropic's EN285x MoCA 2.0 chip supporting up to 500Mb/s as well as the Silicon Labs Si2177 Hybrid TV tuner with an analog TV demodulator. With the MoCA backbone, the reference design enables a higher-quality connection, Quality of Service (QoS), and immunity to noise and interference from wireless networks and devices, which is necessary for advanced 4K/Ultra High Definition (UHD), over-the-top (OTT) and TV/Internet interactivity. In addition, by using Silicon Labs' fifth-generation universal hybrid tuner, TV manufacturers can leverage the flexibility that MoCA enables across all TV segments, digital and analog alike.

The Entropic/Silicon Labs reference design boasts enhanced wired-based TV experiences. Although WiFi is ubiquitous, its ubiquity can cause interference, bandwidth issues and limitations in WiFi data rate distance. By using a wired coax-based TV-to-Internet connection via the Entropic/Silicon Labs solution, consumers get a better TV viewing experience without wireless service degradation or noise.

It also claims to deliver greater TV viewing performance. MoCA delivers higher network speeds, going from 175-500Mb/s at the TV, which is needed for high-bandwidth OTT and 4K/UHD content. The emergence of new Remote User Interface (RUI) standards such as RVU and CVP-2 require a reliable network backbone, which would benefit from the Entropic/Silicon Labs solution. Additionally, with MoCA integrated into the TV, lower implementation costs exist; and the Entropic/Silicon Labs reference design sets the stage for making the TV the wireless extender for WiFi as compared to making the TV the receiver of WiFi, which would extend wireless coverage to more devices in the home, noted the firms.
