Abstract: For playing an order program in the present invention, an order program request signal is sent from a digital television receiving terminal. Then linkage program request information is generated and parsed according to the order program request signal. Search the preset recording list according to user identification information to locate a program breakpoint time, wherein the recording list is used for storing and correlating user identification information to program breakpoint time. The located program breakpoint time is set as a playback start time specified in the parsed linkage program request information, and then the linkage program request information is reformed. The digital television receiving terminal is controlled to play the order program from the playback start time specified in the reformed linkage program request information, thereby accomplishing breakpoint resuming of the order program so as to allow a user to watch the order program as desired.
