Abstract:
A method for receiving, in a receiver, broadcast data propagated by a multiplexed and modulated digital signal, the signal including video data and at least one elementary stream conveying the broadcast data, the broadcast data including a header and, if necessary, a payload, the receiver including: (i) a tuner for tuning to the signal under control of a user of the receiver; (ii) a demodulator, coupled to the tuner, for demodulating the signal to generate a transport stream conveying the broadcast data; (iii) a data processor responsive to control signals from the user for processing the broadcast data; (iv) a rewritable memory coupled to the data processor; and (v) a display device for displaying the video data as well as displayable data corresponding to the broadcast data, the method comprising the steps of(a) applying power to the tuner, the demodulator, the data processor, and the rewritable memory independent of the on-off state of the display device,(b) generating and storing a table in the rewritable memory to be filled in by the data processor,(c) processing in the data processor the header to obtain field information conveyed by the header,(d) if the field information indicates that the broadcast data contains a filename to be stored, storing the filename and the payload of the broadcast data corresponding to the filename in the rewritable memory, and proceeding to step (f),(e) if the field information indicates that the broadcast data contains a location to be stored, storing the location in the rewritable memory, and(f) storing at least some of the field information as an entry in the table for later recall by the user.
