Method for implementing data interchange between optical network terminal and customer terminal using household gateway

Abstract

A method using home gateway to realize data exchange between an optical-network terminal and a user end solves the technical problems of the synchronization conversion between digital video signals and audio signals, the realization of long-distance high-speed internet access and the integrated use of network telephone. The method adopts the technical proposal that optical pulse data from an optical-network terminal is received through an optical network and the connection between an optical-network module and an optical-fiber interface which are installed in the home gateway, the optical pulse data is transferred to all functional modules by classification after undergoing photoelectric conversion and is transmitted to the signal inputting end of an externally-installed device of the user terminal through an accompanying interface circuit, the user realizes connections and the information exchanges between remote terminals with the aid of the external installation of the device, by sending commands and requests to the home gateway, and with the aid of the home gateway arranged on a destination terminal. By using a master chip to process and convert the digital video singles and the audio singles, and with the corresponding externally-installed interface arranged on the gateway, the method realizes an integrated home gateway integrating the uses of a computer, a telephone, a fax machine, an IPTV and other externally installed devices.

Description

technical field

[0001] The invention relates to a home gateway, in particular to a method for realizing data exchange between an optical network terminal and a user end by using the home gateway in an optical network system for realizing fiber-to-user. Background technique

[0002] With the gradual enrichment of broadband applications and the continuous reduction of costs, people's demand for communication bandwidth is increasing day by day. ADSL technology is currently the mainstream means of broadband access for families and small and medium-sized enterprises. With the continuous and rapid development of the Internet, various value-added services continue to emerge, and video conferencing, Online Gaming, IPTV, video surveillance, and Internet telephony applications have great impact on network access. Bandwidth puts forward higher requirements. The current broadband mainstream technology ADSL has many shortcomings such as large loss during transmission, narrow frequency b...
