Blue tooth multifunctional remote controller device and method for implementing voice communication

Abstract

This invention discloses a blue-tooth multifunction remote controller and a method for realizing phone communication including: a blue-tooth module used in finishing RF T-R and its low baseband protocol process and providing control interfaces of a standard host computer and a processor module for finishing protocol stack process of middle and upper layers and the control of the whole system, in which, the processor module includes: a multi-point control unit, a 2-line asynchroinous serial interface, a 4-line asynchronous serial interface and at least one GPIO interface, and the blue-tooth module is connected with the multi-point control unit of the processor module via the 4-line asynchronous serial interface or the 2-line USB interface to further realize phone communication with the device and a set-top box.

Description

Technical field [0001] The invention relates to a Bluetooth multifunctional remote control device, in particular to an IPTV (Internet TV) set-top box remote control device with voice function based on Bluetooth technology and a method for implementing Internet voice communication using the device. Background technique [0002] With the rise of IPTV (Internet TV), the "voice, data and video" three-in-one Internet service has received widespread attention. Generally speaking, the control of various business functions of the IPTV set-top box can be accomplished by using an ordinary wireless remote control. For example, video on demand, IP phone, video phone, basic rotation, tilt, zoom control of the camera, TV picture, color, volume, etc. If services such as IP phone, video phone, etc. are activated, the phone needs to be connected to the phone port provided by the set-top box to complete the corresponding voice function. It can be seen that when using IPTV services, it is often n...

Problems solved by technology

But infrared technology has its limitations: infrared is a point-to-point data transmission protocol, the transmission baud rate is generally only a few K levels, the communication distance is relatively short, generally about 10 meters, it is not penetrative, and it supports voice functions Hardly any, and wireless access is even more impossible

Therefore, it is basically difficult to use infrared technology to realize remote control, voice communication, and broadband Internet access to IPTV set-top boxes.
