Abstract: Data for one, or more, services is encoded using a scalable channel code and divided for transmission over N transmitters such that reception by a receiver of at least M of the transmitted signals, where M<N, enables recovery of the data by the receiver. In other words, even if reception for any one particular transmitted signal in a defined geographical region is not guaranteed, reception of at least M of the other transmitted signals enables reception of the service(s). Thus, one, or more, services can be offered across an entire geographical area notwithstanding the existence of areas of poor, or no, reception.

Abstract: A portable device (200, 210) comprises a power source (70) and a processing system (15, 20, 25, 30, 35) for processing media content received from a service provider (100) via a delivery channel. A control apparatus (50, 60) determines remaining capacity of the power source (70) and receives information from the service provider (100) about available delivery parameters for an item of content. The control apparatus determines an operating duration for the device based on the delivery parameters and the remaining capacity of the power source and sends a request to the service provider (100) specifying at least one delivery parameter for delivery of the content. By specifying what format the service provider (100) should deliver the content, power savings can be made in the processing (20, 30) and rendering (25, 35) stages and in the receive chain of the portable device. Selection of delivery parameters can be automatic or under user control.

Abstract: A system for the efficient distribution of live and stored audio/video streams to multiple subscribers without degrading normal data delivery services. The system segments one or more frequency bands into sub-bands, or channels, each of which is capable of carrying encoded audio, video, and other data streams, to a plurality of subscribers. Each channel transmitted in the system provides full-duplex operation so that each subscriber may indicate what specific services are desired, such as audio/video broadcast, two-way data transfer, video library access, pay-per-view video, interactive video, and audio file transfer. A transmission headend facility (‘hub’) broadcasts multiple channels of video/audio data (e.g., Internet data) in unicast mode via a shared media transmission facility to multiple subscribers. Simultaneously, selected video/audio/data is transmitted in Internet Protocol multicast mode over one or more channels of the segmented frequency band.

Abstract: A system and method for monitoring and adjusting the data transmission rate of a forward link RF signal from a base station to a mobile platform to maintain a desired, minimum link margin with each of the mobile platforms. The system involves using a signal quality monitoring subsystem carried by each mobile platform during the normal course of its operation to transmit signal quality information via a return link to the base station.

The present invention better accounts for time varying factors that influence the signal quality of received forward link signals by the mobile platforms and obviates the need for mobile test platforms or other expensive and relatively complex methods for predicting needed data transmission rates for the forward link signals.

The receiver system extracts a subset of digital information streams that the particular receiver system's owner has designated are of interest. The receiver system caches the interesting digital information stream for later access. The receiver system outputs the interesting digital information streams to a client system upon demand.

Abstract: A receiver includes a CPU. The CPU, when executing preset registration, in step S1 first searches for the presence or absence of receivable channels. If there are receivable channels, received data (center frequency, etc.) is registered in step S2. If the received channel is a TV channel, filtering is carried out in step S4 to count only the channels existing within a range of ± approximately 200 kHz of a center frequency. If it is a CATV channel, counting is further made in step S5 on the channels existing within the range of ± approximately 200 kHz of the center frequency, and a filter process is carried out in order to remove the channels within the range of ± approximately 200 kHz of the center frequency +2 MHz of a CATV UHF-band channel overlapped with a TV channel.
