摘要:
A system for and method of implementing mobile commerce in a satellite radio broadcasting system. A unique program identifier is associated with each program segment of a broadcast. When a listener hears a program segment of interest, the listener causes the associated program identifier to be captured and thereafter to be transferred to a central location or hub. The transferring operation can be accomplished manually, via a media link or via a wireless network. Upon receipt of the program identifier at the central hub, the program identifier is used to determine information about the listener, obtain additional information regarding the program segment associated with the program identifier for the listener and/or initiate an e-commerce transaction involving the listener and/or other parties including merchandisers and advertisers.

摘要:
Various applications, systems and methods for using, and enhancing V2V communications for various purposes are described. These systems and methods leverage various aspects of satellite radio broadcasts in combination with V2V communications. In some embodiments, V2V-enabled vehicles can receive advertisements or offers from RSEs, or even other V2V enabled vehicles, in a defined Target Region, which may then be played to a user in-vehicle once a given Trigger Region has been entered. By logging all advertisements or offers played to a user and sending the log to an RSE, for example, and from there to a content provider (e.g., an SDARS service operator), verified delivery of advertisements is achieved, which allows the content provider to obtain significant revenues from advertisers. In return for uploading the playback record from the vehicle to the RSE, a variety of incentives may be offered, such as (i) free or discounted satellite radio subscription; (ii) download credits for music or videos from an online store; (iii) reduced or free tolls on toll roads (e.g., RSE embedded in a toll collection plaza); (iv) premium audio or video content, (v) credit at an online store; and (vi) a special coupon code redeemable for merchandise.
摘要:
A device (100) for receiving, storing and playing back digital audio radio signals comprises a receiver (203), a decoder (502 and/or 504), a user input (516), a storage medium (510) coupled to the decoder, and a system controller (508) coupled to the user input. The receiver receives a digitally encoded bit stream (300) on a plurality of communication resources (104), wherein each communication resource contains content and associated index information. The decoder selectively decodes a selected plurality of communication resources and the user input selects the selected plurality based on the associated index information and selects a portion of the content contained in selected plurality to be retrieved. The storage medium stores the content and associated index information contained in the selected plurality of communication resources and the system controller stores and retrieves content to and from the storage medium based on input received at the user input.

A digital receiver unit (28) having a backup energy source (214) for use in a vehicle (250) that operates on a primary energy source (216) includes a receiver (203) powered by the primary energy source when the vehicle is operating, a switching mechanism (210 and 212) for switching the receiver between the primary energy source and the backup energy source and a controller (210) coupled to the receiver for controlling the switching mechanism. The receiver receives data during a scheduled predetermined time and the backup energy source powers the receiver during the scheduled predetermined time if the vehicle is not operating.

A receiver unit (500) capable of combining a plurality of streaming data channels includes a receiver and a channel decoder (510) for receiving over the air in a time division multiplex signal the plurality of streaming data channels. The receiver unit further includes at least one decoder (502) for decoding at least two of the plurality of streaming data channels to provide a plurality of decoded signals, a combiner (508) for combining the plurality of decoded signals to provide a combined signal, and an audio output for outputting the combined signal as audio.
摘要:
A receiver adapted to receive a signal having at least first and second carrier frequencies on which first and second information signals are modulated, respectively. The inventive receiver further includes circuitry for converting the received signal to a complex baseband signal. In the illustrative embodiment, the received signal includes first and second ensembles. The first ensemble includes a first signal from a first source, a first signal from a second source and a first signal from a third source. The second ensemble includes a second signal from the first source, a second signal from the second source and a second signal from the third source. The receiver is adapted to selectively output the first and/or the second ensemble. Conversion of the band is achieved with quad mixers. The outputs of the mixers are digitized and selectively provided as the first and/or the second ensemble by a digital translation stage.
摘要:
A method and apparatus detects (516) a baud rate in a digital signal (442). An N-state counter (404) counts at a rate N times the baud rate and the digital signal is sampled (504) to detect transitions of the digital signal. N tallies (202) record how many transitions occur coincident with each of the states of the counter, and a total number of transitions detected is computed (508). M groups (204-210) of the tallies are formed (510) corresponding to contiguous sequential states of the counter, and for each group a group number is calculated (512) indicating how many transitions are recorded in the tallies of the group. Each group is defined (514) transitional if the group number exceeds a percentage (413) of the total number of transitions, and the baud rate is determined present or absent based upon the groups that are defined as transitional.
摘要:
A method and apparatus in a digital wireless communication system (100) controls an inter-cell hand-off. First and second fixed units (102) receive a common synchronization signal from a controller (104), and a first wireless link is established between the first fixed unit and a portable unit (120) on a first frequency. The first wireless link is synchronized to the common synchronization signal, and frame synchronization is obtained between the fixed unit (102) and the portable unit (120) during establishment of the first wireless link. Frame synchronization is maintained only by maintaining bit synchronization while transmitting user data on the first frequency. A second wireless link is established between the second fixed unit (102) and the portable unit (120) on the first frequency if the first frequency is usable therebetween. The second wireless link is synchronized to the common synchronization signal. The first wireless link is disconnected after the second wireless link is established, thereby seamlessly completing the inter-cell hand-off.
