1. A method for providing interactive program guide (IPG) to a plurality of terminals, the method comprising:

  • coding a first sequence of pictures having included therein a time-varying portion;

    defining one or more slices for the time-varying portion in each coded picture in the first sequence;

    assigning the coded first sequence with a first packet identifier (PID);

    coding one or more second sequences of pictures, wherein each second sequence of pictures includes a portion specific to the sequence;

    defining one or more slices for the sequence-specific portion in each coded picture in each second sequence; and

    assigning each coded second sequence with a respective second PID;

    multiplexing packets with the first PID with packets with the second PIDs to generate one or more transport streams.
