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 a bluetooth technology-based IPTV (Internet Television) set-top box remote control device with voice function and a method for implementing Internet voice communication using the device. Background technique [0002] With the rise of IPTV (Internet Television), the three-in-one Internet service of "voice, data and video" has received extensive attention. Generally speaking, the control of various service functions of the IPTV set-top box can be completed by using an ordinary wireless remote controller. For example, video on demand, IP telephony, videophone, basic camera rotation, tilt, zoom control, TV picture, color, volume, etc. If services such as IP phone and video phone are activated, it is necessary to connect an external phone through the phone port provided by the set-top box to complete the corresponding voice function. It can be seen that when using...

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.
