摘要:
A method (700) of customizing the selection of channels among a plurality of channels includes the steps of receiving (702) a digitally encoded bit stream over-the-air on the plurality of channels and decoding (704) a selected channel among the plurality of channels. The method further comprises the steps of selectively tagging (706) a desired type of content on the selected channel, analyzing (708) a broadcast information channel and/or an Electronic Program Guide for an indication of content of the desired type among the plurality of channels, and alerting (710) a user of a desired channel containing the indication.

A method of disabling at least a portion of one of a plurality of channels in a digital audio radio system includes the steps of receiving (702) a digitally encoded bit stream over-the-air on the plurality of channels and decoding (704) a selected channel among the plurality of channels. The method further comprises the steps of selectively tagging (706) an undesired type of content on the selected channel, analyzing (708) for an indication of content of the undesired type among the plurality of channels, and selectively disabling (710) at least the portion of the selected channel containing the undesired type of content.
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:
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 vehicle messaging method (600) and system (100) can include any number of data sources (101-103), an interface (104) that formats messages and addresses from the data sources, and a corresponding number of messaging servers (111-113) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller (121-123) programmed to assign (604) targeted messages to a predetermined channel and encode (606) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer (608) the targeted messages and addresses to a satellite uplink (107) and satellite (110) via a messaging uplink interface (106) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.
摘要:
A channel scanning communication receiver (204) operates in a system that transmits information in cycles (104) including subsequences (106). The receiver determines whether to operate in a scanning or locked mode by making (302) signal quality pass/fail decisions for subsequences transmitted in a predetermined group of cycles. A decision is made for a transmission of a subsequence, and subsequence active/inactive decisions are made (304) for the subsequences transmitted in the predetermined group of cycles, based upon the signal quality pass/fail decisions made for the subsequences. The receiver determines (306) whether the system is time-shared or continuous, based upon how many active decisions and inactive decisions are made, and selects (310, 312) the scanning or locked mode in accordance with predetermined rules for time-shared or continuous systems, according to whether the system is time-shared or continuous.
摘要:
A method (300) and system (100) for sharing a controller for a combined cellular phone and satellite radio includes a cellular phone module (102), a satellite radio module (106), and a controller module (108) having a digital signal processor (120) shared by the cellular and satellite modules. A base band processor (118) of the satellite module can provide a digital audio output (107) to a stereo decoder (122) of the controller module and a base band module (112) of the cellular phone module can provide a digital audio output (109) to the stereo decoder. The base band processor of the satellite module can provide compressed audio (111) to the DSP for longer term storage within a memory (129). The DSP can also receive control signaling (113) from the base band processor of the satellite radio module and control signaling (117) from the base band processor of the cellular phone module.
摘要:
An interoperable receiver adapted to receive signals in multiple SDARS bands. The advantageous operation is afforded by the design of the receiver by which an entire band consisting of multiple carriers is received at one time. Receipt and processing of each SDARS band signals is then effectuated by retuning a synthesizer as necessary. In the illustrative embodiment, the invention further includes circuitry for simultaneously receiving first and second ensembles. The first ensemble including 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 including a second signal from the first source, a second signal from the second source and a second signal from the third source. In a preferred embodiment, the inventive receiver is adapted to receive and output audio signals along with data signals simultaneously.
摘要:
The invention relates generally to a receiver unit in a digital broadcast system for receiving a broadcast signal comprising content segments and control data, and generating an output signal using the content segments and previously stored content segments. The previously stored content segments are retrieved from a local memory device using the control data and inserted among the received content segments.
