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

● High end: (BLE SoC + Sensor）：Air-Mouse/Gesture + Audio + RF

● 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.
