<p>The present invention provides a system and method of cable network defined by software. A programmable chip is adopted in the client side terminal, the chip can implement a new protocol by downloading a program from said head-end server device, or by reading a program from storage media into said client side terminal, to realize the reprogramming of the chip and thereby to modify the functions of the cable network system. Once the head-end server device is renewed or upgraded, without having to renew or upgrade the client side terminal, the protocol performed by said client side terminal can be maintained consistent with the protocol performed by the head-end server device though a process of reprogramming said chip, thus, the cable network system is upgraded. <IMAGE></p> |
