摘要： A receiver in a digital broadcast system is provided for storing broadcast content files for on-demand playback purposes. The content files are transmitted in a partitioned format. Users can select which content files are to be captured in a memory device following reception. The receiver is operable to monitor the reception of content file segments and, when a selected on-demand content file has been completely received, to generate an alert message to notify a user that the content is available for retrieval from the memory device and playback via an output device.

摘要： A method and apparatus for mitigating error in a received communications signal includes an error mitigator (35) of a communication unit (12) which receives and performs mitigation based on an error indication. In a first embodiment the error indication is a phase or non-used data symbol indicating error in ADPCM data, and mitigation includes changing certain nibble values to different predetermined values. In a second embodiment the error indication may include other parameters, e.g., a CRC frame error indicator, and an error estimator (34) determines a level of corruption in the ADPCM data. The error mitigator (35) applies a predetermined set of replacement values based on the indicated level of corruption and the mitigated data is subsequently decoded in an ADPCM decoder (26).

摘要： A nested digital phase lock loop (DPLL) circuit (400) provides center bit sampling for incoming recovered data (406). Included in the nested DPLL circuit (400) are a narrow bandwidth DPLL (402) and a wide bandwidth DPLL (404) which generate first (410) and second (428) recovered clock signals respectively. Initially the first recovered clock signal (410) is used to clock in the recovered data (406) until the narrowband DPLL (402) is stabilized. Once the narrowband DPLL (402) is stabilized, the second recovered clock signal (428) generated from the wideband DPLL (404) is switched in by a multiplexer (424). If for any reason the center bit sampled data becomes corrupted, a RESET occurs in the wideband loop (404) to zero out the phase shift of the second recovered clock signal (428) to match that of the narrow loop. Thus, when a RESET occurs, the wideband loop is tracking at exactly the same clock rate as the narrowband loop.

摘要： A base station allocates radio channels to radio telephone handsets in a second generation cordless telephone (CT2) communication systems by scanning each channel in a first band, and scanning each channel in a second band to measure an RSS level for each channel scanned. The base station scans the second band at a rate that is substantially faster than the rate at which it scans the first band. If a link request is received on a first channel within the first band, from a calling radio telephone, the base station determines whether the first channel has an RSS level above a predetermined threshold. If the RSS level of the first channel is above the threshold, and the calling radio telephone handset is capable of operating on the second band, the base station re-assigns a second channel, that is within the second band, to the calling radio telephone handset.
