Abstract

The invention provides a set-card separation method for realizing a DVB-CI standard and a digital TV receiving terminal using the method; wherein, the set-card separation digital TV receiving terminal for realizing the DVB-CI standard comprises the digital TV receiving terminal, a DVB-CI module for storing application software for running of the digital TV receiving terminal, and a connecting device which is arranged on the digital TV receiving terminal and is used for connecting the DVB-CI module and the digital TV receiving terminal in a detachable way. The technical scheme of the invention solves the independence of a terminal receiver and value-added services.

Description

technical field [0001] The invention relates to the field of digital television, more specifically, to a machine-card separation method capable of realizing the DVB-CI standard and a digital television receiving terminal using the same. Background technique [0002] Currently digital TV (including handheld TV) is becoming more and more popular. Digital TV can be divided into terrestrial digital TV, cable digital TV and satellite digital TV according to the transmission link. Handheld TV refers to a system that uses portable terminals to receive broadcast TV signals. Portable terminals include but are not limited to mobile phones. [0003] In the field of digital TV (including handheld TV, such as mobile phone TV), the following methods are generally adopted: use the front-end system of Conditional Access System (Conditional Access System, referred to as CAS) at the front-end (such as the broadcasting organization) to encrypt TV programs and encrypt the purchased TV. The us...
