Problems solved by technology

Limited to the current test method, if a large amount of testing manpower cannot be afforded, the manufacturer of the TV system usually can only randomly select a few products, and after a large number of plugging and unplugging operations of the smart card module by the tester, the smart card used for the test will inevitably produce physical wear and tear , resulting in unnecessary testing costs

Abstract

The invention provides a testing apparatus of an intelligent card module for a television system. The testing apparatus is composed of a control unit, a first interface, a second interface, a signal line group, a switching module and an impedance adjusting module. The apparatus is connected with an intelligent card by the first interface and is connected with a television system by the second interface. The control unit is used for generating a switching signal, an impedance adjusting signal, and an operating signal; the switching signal is used for controlling the switching module to control a signal line conduction state of the signal line group; the impedance adjusting signal is used for controlling the impedance adjusting module to adjust the impedances of the signal lines in the signal line group; and the operating signal is transmitted to the television system by the second interface. Therefore, the television system can use the testing apparatus to carry out data access on the intelligent card, thereby completing correlated testing items of the intelligent card.

Description

technical field [0001] The present invention is related to the test technology, and especially relates to the test technology applied to the smart card module of the digital TV. Background technique [0002] In most multimedia systems, the most important hardware device is an image display device. How to ensure that the functions of the products are normal when they leave the factory and meet the functional specifications of various sales regions has always been a topic of concern for image display device manufacturers. The smart card can be used in the conditional access module of digital TV, and it is the system control center of digital TV in multimedia services, value-added services, paid entertainment, etc., through the key and identity information on the smart card, it is further used in the charging mechanism of the TV system . Due to the different policies and specifications for digital TV in different regions, and the different policies and specifications for smar...
