Data broadcast over different channels may be updated in a digital broadcast receiving device. The device may include a receiver unit, a processor, memory instructions embodied in the memory for execution on the processor. The instructions may be configured to implement the method for updating data broadcast over different channels. A first digital broadcast signal may be received over a first channel. The receiving device may be tuned to a second channel at a predetermined time to receive a second digital broadcast signal. Selected data may be extracted from the second digital broadcast signal and stored or utilized with the receiving device. An update schedule may be generated for data transmitted with a digital broadcast signal. A broadcast time for an update packet may be determined from a packet header. A schedule packet may be generated containing the broadcast time and broadcast before the update packet.
