Abstract

The invention discloses a data transmission method and system for a digital TV terminal. The method is as follows: a user terminal sends a code scanning request to a management terminal, and the management terminal sends a two-dimensional code display instruction to the subscriber's set-top box according to the scanning request, and the subscriber The set-top box generates a two-dimensional code containing subscriber data according to the two-dimensional code display instruction, and displays the two-dimensional code on the screen played by the digital TV terminal, and the subscriber scans the two-dimensional code displayed on the digital TV terminal through the user terminal, and then The two-dimensional code data obtained by scanning the two-dimensional code is sent to the management terminal. Therefore, the present invention can instantly display the two-dimensional code on the digital TV terminal according to the needs of the subscriber, so that the subscriber can conveniently scan the two-dimensional code at any time and realize the return of subscriber data.
