Interactive program guide (IPG) data is delivered to a receiver from which a program guide can be retrieved. The IPG data includes schedule-data for each of a plurality of time slots, description-data for each of the plurality of time slots, and non-time-sensitive foundation data. The IPG data is delivered by the steps of: (a) delivering a plurality of segments of foundation data having a predetermined closed-loop order; (b) delivering the schedule-data segments for a first time slot; (c) delivering the description-data segments for a first time slot; (d) delivering the schedule-data segments and the description-data segments for each of the remaining time slots; (e) subsequent to the delivery of the first schedule-data segment for each time slot, during a gap of sufficient duration to enable the receiver to allocate memory space for storing all of the schedule-data segments for the time slot, delivering the next non-time-sensitive foundation-data segments in the predetermined order for use by the receiver; and (f) subsequent to the delivery of the first description-data segment for each time slot, during a gap of sufficient duration to enable the receiver to allocate memory space for storing all of the description-data segments for the time slot, delivering the next non-time-sensitive foundation-data segments in the predetermined order for use by the receiver. Subsequent to step (f), the next given number of foundation-data segments in the predetermined order are delivered until all of the foundation-data segments have been delivered at least twice.

Delivery of interactive program guide data

An apparatus for receiving signals includes a low noise amplifier (LNA) configured to receive a radio frequency (RF) signal. An I/Q direct down converter is coupled to the LNA. The I/Q direct down converter is configured to split the RF signal into real and imaginary components and to down convert the real and imaginary components directly to baseband signals. A local oscillator (LO) is coupled to the I/Q direct down converter and is configured to drive the I/Q direct down converter. First and second filters are coupled to the I/Q direct down converter. The first and second filters are configured to filter the down converted real and imaginary components, respectively. First and second analog-to-digital converters (ADCs) are coupled to the first and second filters, respectively. The first and second ADCs are configured to convert the real and imaginary components into digital signals. The first and second ADCs have a dynamic range that is wide enough to convert the filtered, down converted real and imaginary components to digital signals without using variable gain on the filtered and down converted real and imaginary components. An apparatus for use in wireless communications includes a radio, a modem and a controller integrated onto a single integrated circuit (IC). The radio includes a receiver for receiving data and a transmitter for transmitting data. The modem is coupled to the radio and is configured to demodulate received data and modulate data for transmission. The controller is coupled to the modem and includes a digital interface for external communications through which received data and data for transmission is sent, a connection state machine configured to accept commands through the digital interface and to respond to the commands by initiating a sequence, and a receive/transmit state machine configured to perform state control of the radio in response to the initiated sequence.
