Embodiment Construction

[0112] As shown in Fig. 1 and Fig. 2: among Fig. 1, set up the connection with the Internet of the Cable-IP.-Lan of PSTN or ADSL-Lan, CATV-HFC by RJ11 or RJ45 port, restored voice or RF again by device of the present invention , V / SV, A and other radio frequency, high-definition TV signals or stereo signals are sent to telephones, TV sets and stereos through the RJ11 port.

[0113] In Figure 2, the user's media terminal requires high intelligence, which is very different from the traditional telephone. The IP terminal in the softswitch network generally includes: network access part (10 / 100Mbps Ethernet interface), TCP / IP protocol stack, CODEC protocol stack, DSP processor, embedded CPU, embedded operating system, application program, etc. The softswitch network through the fixed network includes media gateway controller (MediaGatewayController), application server (ApplicationServer), trunk network (TrunkGateway) gateway, access gateway (AccessGateway), signaling gateway (Sig...

Abstract

This invention relates to the application and communication method for network media telephone terminals. The terminal includes a phone module and IP phone module imaging the target called number into related network IP address for Volp communication, PCI bus with Ethernet interface and phone/multimedia processor controlled by CPU, the media port is connected by D/A conversion, a special inserted CPU, TCP/IP protocol stack the real time transmission protocol of the transmission stream media. The terminal and the software exchange center based on IP interact synchronously or asynchronously, and the IP calling cetral platform provides support to communication for stream media forms and speech.

Description

technical field [0001] The invention relates to a broadband network terminal with the function of a media phone, its application and a communication method. Background technique [0002] Broadband networks and their applications are entering more and more fields and users (including business and home users); these developments include: - Broadband IP network LAN access has become popular [0003] ——The popularization and application of ADSL technology for composite data communication in the fixed telephone network and the maturity of VOIP technology [0004] ——Promotion of 2.5G-GPRS / CDMA1X technology for composite data communication and promotion of 3G application in mobile network [0005] ——Promotion of Internet-based IP network to IP-V6 [0006] ——The introduction of CATV network HFC composite IP data communication (including VOIP technology) and the development and application of digital TV. [0007] But at present, the ...
