Abstract:
A technique (200) for addressing frame loss in a video system includes a number of steps. Initially, a first video stream and a second video stream are received (202). The first and second video streams each include related video information having a plurality of video frames. At least one of the first and second video streams is buffered (204) and lost or corrupted video frames associated with the first video stream are replaced with uncorrupted video frames from the second video stream (206,208).
Abstract:
A satellite-based digital audio radio (SDAR) receiver buffers an audio or video data stream and obtains metadata relating to the content of the data stream either during or after the transmission of the data stream in SDAR services in which a priori information is unavailable. Based on the metadata and on a selection criterion, the receiver selectively stores portions of the data stream for subsequent use. Thus, the SDAR receiver may provide a user with functionality approximating "content on demand" capabilities of other streamed data services without the use of a priori information that is unavailable in some SDAR services.
Abstract:
The present invention involves a method and system for transmitting data in an optical or hybrid optical and RF wireless network from a base structure (10, 110, 111) including a base apparatus (120) to a target device including a target apparatus (140). The base apparatus includes a base receiver (122), a laser (126), a device for positioning a laser-emitted beam (128), and a base microprocessor (124). The target apparatus includes a target transmitter (142), a photodetector (146), and a target microprocessor (144). Once the target device comes to a rest beneath the base structure, the target transmitter communicates the presence of the target apparatus to the base receiver. A communication uplink is established between the target apparatus and the base apparatus. The base microprocessor then activates the laser and instructs a commercial laser based steering system to continually adjust the position of the laser beam in a search pattern until it illuminates the photodetector, at which time a communication downlink is established between the base apparatus and target apparatus. Data is then transmitted from the laser to the photodetector via the communication downlink at speeds of 100 Mbps to 10Gbps.
Abstract:
A communication system (10) and method (100) for communicating data is provided. The communication system (10) includes at least one base station (12) that transmits common data within a range of the at least one base station and a plurality of nodes (14). The plurality of nodes (14) include at least a first node in communication with at least one of the at least one base station (12) and at least a portion of other nodes of the plurality of nodes (14). At least one of the plurality of nodes (14) are mobile, and the plurality of nodes at least one of advertise the common data available for transmission while within a predetermined area (16) and receive the common data from one of a current node of a plurality of nodes (14) that has current common data and the at least one base station (12).
Abstract:
A system and method for controlling communication modes of a personal communication device traveling in a vehicle. The system includes a communication center configured to provide communication services, a personal communication device (PCD) configured to communicate with the communication center, and a controller installed in a vehicle. The communication center is configured to selectively disable any of the PCD communication modes when the PCD is residing or traveling in the vehicle. Which communication modes are disabled may be based on a customer profile. The system and method provide a way for a parent to limit the communication modes of PCD used by their child, especially when the child is traveling in and presumably operating a particular vehicle such as the family car. The system and method may also be used by employers to limit the PCD communication modes available to employees operating company vehicles.

Abstract:
A system (10) and method of injecting audio content into a radio system is provided. The method includes the steps of receiving in a radio receiver (12) a first RF signal from an antenna (18) and processing the signal at a select frequency within a radio frequency band. The method also includes the step of providing audio content from an auxiliary device (22). The method also includes the step of modulating the audio content from the auxiliary device (22) and replicating the modulated signal to generate a replicated RF signal at the multiple frequencies within the radio frequency band. The method further includes the step of injecting the replicated RF signal into the radio receiver (12).
