Abstract

The invention discloses a communication system based on a set-top box and a communication method. The system comprises a set-top box and a remote control; wherein the remote control comprises an audio capturing module which is used for capturing user voice through a microphone and transforming the user voice into a digital audio signal, a video capturing module which is used for capturing user images through a camera and transforming the user images into a digital image signal, and a data transmission module which is used for transmitting the acoustic or image signals to the set-top box in a wireless way; and the set-top box comprises a digital transmission device which is used for receiving the acoustic or image signals, a video telephone function module which is used for encoding and decoding received signals, transforming the signals to signals in the form of an SIP protocol to be transmitted to a network side, transforming the signals in the form of the SIP protocol on the network side into special television signals, outputting the television signals to a television for display, and transmitting voice signals to the speaker of the remote control for playing through a data transmission device. The invention can simply realize the communication through the IP set-top box.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a communication system and method based on a set-top box. Background technique [0002] The basic function of the IP set-top box is to receive digital TV programs, and at the same time have all broadcasting, on-demand and interactive multimedia application functions. The basic working principle of the IP set-top box is to receive and decompress network audio and video media data, convert it into a TV signal format and send it to the TV festival for playback. Videophone refers to software or terminals that can transmit audio and video through a medium, and the medium can be a telephone line or an IP network. The videophone based on the telephone line uses the H320 protocol, while the videophone based on the IP network uses the H323 protocol or the Session Initiation Protocol (SIP, Session Initiation Protocol 1) protocol. Compared with the H323 protocol, the SIP protocol has...
