Abstract

The invention discloses a method and system for achieving an IP two-direction function. The method and system is used for achieving the IP two-way service function on a one-way set top box. Through selection, an appropriate single chip microcomputer is adopted so that a data link layer and a physical layer in a TCP / IP protocol stack is provided for the one-way set top box to receive and send IP data in a matched mode, an Ethernet controller of the selected single chip microcomputer can be divided into two levels, namely, a medium access controller layer and a network physical layer, according to functions, the two layers correspond to the data link layer and the physical layer in the TCP / IP protocol stack respectively, therefore, the IP two-way function is achieved on the one-way set top box, and a one-way set top box user is made to conveniently enjoy the pleasure brought by an interactive television. In addition, requirements are met through existing devices such as serial ports of the one-way set top box, and refitting cost is low.

Description

technical field [0001] The present invention relates to the technical field of digital television, more specifically, relates to a method and system for realizing IP bidirectional function. Background technique [0002] With the vigorous development of digital TV technology and the in-depth conversion of cable TV in various places, more and more families have come into contact with digital TV services, and the value-added services based on digital TV are also more and more valued by local radio and television operators. However, most of the value-added services are based on the two-way interactive mode, so tens of millions of one-way set-top boxes in ordinary people’s homes cannot carry two-way value-added services. How can low-cost technical transformation be carried out on the existing one-way set-top boxes so that they can realize two-way functions , is also a question worth exploring. [0003] In the current one-way to two-way technical solution, partly by installing a ...
