  • Publication number: 20130121117
    Abstract: A novel and useful system and method for leap second and daylight saving time (DST) correction for use in a radio controlled clock (RCC) receiver. The RCC receiver extracts schedule information from the frame, including the time for the DST transition and whether a leap second needs to be added at the end of this half-year. Linear error correcting coding is used for the leap second and the DST on/off indications, while non-linear error correcting coding (e.g., a look up table) is used for the DST schedule to enhance reception reliability in the presence of noise and interference. The one second/one hour corrections are scheduled to occur when they should take place and the correction is applied exactly when DST or leap second is to go into effect, without having to receive anything around the time of the correction.

  • Patent number: 8395969
    Abstract: Method and apparatus to implement a “virtual” real-time clock at a terminal based on time information from multiple communication systems. At least one system (e.g., GPS) provides “absolute” time information for the virtual real-time clock, and at least one other system (e.g., a cellular system) provides “relative” time information. The virtual real-time clock is “time-stamped” with absolute time as it becomes available from the first system. Relative time (which may be received from multiple asynchronous transmitters) is mapped to the timeline of the virtual real-time clock as it is received from the second system. Absolute time at any arbitrary time instant on the timeline may then be estimated based on the absolute time from the first system and the relative time from the second system. Absolute times from the first system for two or more time instants may also be used to calibrate the relative time from the second system.

    Abstract: Methods and systems of extending battery life of remote battery-operated timekeeping devices by minimizing the number of required synchronizations per unit of time needed to maintain a predetermined accuracy of the devices. The number of synchronizations are minimized by first calculating a time error rate between the remote timekeeping device and a master device over a sample period. Then, a synchronization is delayed and the remote timekeeping device is compensated based on the time error rate. The compensation delays the need for a synchronization yet maintains the predetermined accuracy of the remote timekeeping device. In some embodiments, the remote timekeeping device is compensated and multiple synchronizations are delayed before a new synchronization is necessary to maintain the predetermined accuracy.

  • Patent number: 8286207
    Abstract: A system for initiating scheduled program processing functions such as program display, recording or playback, derives a time clock based on a current time reference indication produced by a particular broadcast source. The derived time clock is used in initiating scheduled processing functions for programs derived from the particular broadcast source and time clocks derived from sources other than the particular broadcast source are disregarded. The system displays a second time clock different to the derived time clock. In addition, the system forms a composite program guide from data from multiple broadcast sources to associate current time reference indications with their corresponding broadcast sources.
