Smart Remote control

Description and Features

With the widespread of Internet based smart TVs and Over-the-top boxes, smart remote control has become an integral part of the user experience. An advanced smart remote control replaces the traditional IR with RF connections for better range, non-line-of-sight connection, and much higher data rate; the smart remote control allows rich functions and features for not only basic TV/Box operation but also abundance of games, apps, and services. Based on the high performance BLE, RF4CE, or 2.4Ghz series RF SoC, our remote control solution offers multiple benefits including: high level of integration, excellent RF performance, low power consumption, and ultra low BOM component counts.

Complete Spectrum of Solutions

● Mid end:(BLE SoC):Audio + RF

● Low end: (BLE SoC) : RF + Key only + IR

● Modularized design for all features allowing easy mix and match

Remote Control Audio key word search



● Audio Codec (no need for external audio Codec)

  1. Support both D-MIC and A-MIC
  1. No need for external speaker amplifier

● Duplex audio supported on single chip

  1. Allows for Headphones on RCU with minimal BOM increase

● OTA voice data compression

  1. ADPCM
  1. MSBC (available in prototype)
  1. Support for RF4CE and BLE stacks at the same time

Manual switch mode: Independent application states between RF4CE and BLE

● External triggers such as special key combinations can be used to switch between two protocols

Automatic mode:

RCU shipped from factory with support for both RF4CE and BLE

● When powered up, RCU automatically searches for either RF4CE STB or BLE STB/TV to pair with

● Once paired the RCU works in the paired mode until factory reset again The Remote control solution can support various peripherals, a selection table is shown as follows.Smart-Remote-control-supplier-in-Taiwan
