摘要： In addition to global index chunks that indicate the order of program portions in a multimedia stream carrying multiple multiplexed programs, index blocks are provided in data chunks of the stream that point to times when particular program portions arrive. This information can be used at the physical or transport layer of a wireless battery-powered receiver by, e.g., a simple state machine to energize the analog receiving circuitry only for as long as necessary to receive information pertaining to a desired program, thereby conserving battery power.

摘要： Apparatus and methods for estimating the frequency of a sleep or slow clock using a fast clock, such as a temperature compensated crystal oscillator. The disclosed apparatus include an estimator having a first counter that receives sleep clock synchronized pulses issuing each cycle of the sleep clock period, yet are synchronized to a fast clock. The slow clock synchronized pulses are counted up to a predetermined number; whereupon a full count signal is issued. A second counter receives the full count signal and increments each time the full count signal is received. A third counter counts fast clock cycles until the full count signal occurs. Based on the number of counts of the slow and fast clock cycles, the frequency of the slow clock may be determined using only the domain of the fast clock for performing the measurement thereby tying accuracy of the measurement to the accuracy of the fast clock. The disclosed apparatus also include an integrated circuit and a transceiver employing the disclosed estimator. Corresponding methods are also disclosed.
