Abstract
A digital television receiving terminal, a positioning method and system thereof are disclosed. Wherein the method includes the steps of: locking a frequency point for receiving a program by a user according to the received on-demand signals input by the user; determining a transmission stream identifier code (TSID) of the frequency point in the TSIDs broadcasted by the locked frequency point; and comparing the TSID with a pre-stored area code, and judging whether the locked frequency point for receiving the program by the user is a valid on-demand frequency point, and if so, the positioning is successful. The present invention avoids the needs of scanning and acquiring the area code when demand is performed by the user each time, thus saving the starting up time, and having strong applicability.
