Abstract: Systems and methods are presented to facilitate caching of programming from broadcast and/or content streaming services to a user device for local playback. In addition, metadata can be provided to guide the user in selecting, caching, or playing the cachable content. In some exemplary embodiments, a receiver or other user device can automatically select the programming to be cached based on a user's historical topic interest and listening history. In some exemplary embodiments, the metadata can also include DRM information that can limit the ability of a user to playback the content, so as to comply, if necessary, with operative legal requirements related to usage of the content.

Abstract: 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.

Abstract: Various multiple methods of data transport, and combinations thereof, may be used to initialize or update conditional access information on various devices. In an integrated device having both a broadcast receiver, such as an SDARS receiver, and a two-way communications transceiver, such as an LTE, 3G, 4G or 5G modem, or the like, conditional access information for the broadcast receiver may be sent to the transceiver, and then passed to the broadcast receiver, or vice versa. Additionally, for example, the broadcast receiver may be sent, over the broadcast communications channel, a “wake-up” message for the two-way transceiver, which message may then be passed to the two-way transceiver, so as to make it ready to receive conditional access information over the two-way communications channel, or vice versa. Moreover, because of the presence of a two-way communications path, various acknowledgements of conditional access status updates received and processed by the broadcast receiver may be sent—thus realizing a significant improvement over the current practice of sending multiple periodic messages over the broadcast channel, to insure (but never have confirmation of) receipt.

Abstract: Apparatuses and methods are provided to inform a user of a broadcast stream, which has multiple, concurrently received channels of program content, about recommendations of a subset of the content currently playing across the available channels or to be played within a selected future time period. The subset of content is selected based on user preferences and system data (e.g., program topic and channel affinities among the broadcast content and channels) to recommend a more diverse subset of content than would be discovered if only user preferences were employed to make the selection of recommended content.

Abstract: Systems, algorithms and methods for reclaiming unused portions of a satellite broadcast service's bandwidth for new services, utilizing higher performance coding techniques to yield better throughput, are presented. These systems, algorithms and methods achieve the reclaimed bandwidth in a way that is invisible to a legacy receiver, and that does not interfere with its reception of a legacy signal. In one embodiment, new data may be transmitted within a legacy transmission frame, for example within its cluster structure, using the same modulation and synchronization as used for the legacy data. The new data may be inserted into a channel or other subdivision at a head end. In another embodiment, one or more clusters or subdivisions with only new data may be transmitted, using the same modulation and synchronization as the legacy data clusters, but now employing a higher performing FEC and data interleaving structure on those clusters which contain only new data to yield an increase in available throughput. Finally, in a third embodiment, one or more clusters containing only new data may be transmitted, and in said one or more all new data clusters, different modulation and synchronization may be used then that of the legacy data clusters, thus employing a higher performing FEC and data interleaving structure than that of the legacy clusters. Various combinations of these approaches are also presented, as well as a set of novel receivers, or receiver configurations, to implement them and their combinations

Abstract: Systems and methods for increasing transmission bandwidth efficiency by the analysis and synthesis of the ultimate components of transmitted content are presented. To implement such a system, a dictionary or database of elemental codewords can be generated from a set of audio clips. Using such a database, a given arbitrary song or other audio file can be expressed as a series of such codewords, where each given codeword in the series is a compressed audio packet that can be used as is, or, for example, can be tagged to be modified to better match the corresponding portion of the original audio file. Each codeword in the database has an index number or unique identifier. For a relatively small number of bits used in a unique ID, e.g. 27-30, several hundreds of millions of codewords can be uniquely identified. By providing the database of codewords to receivers of a broadcast or content delivery system in advance, instead of broadcasting or streaming the actual compressed audio signal, all that need be transmitted is the series of identifiers along with any modification instructions to the identified codewords. After reception, intelligence on the receiver having access to a locally stored copy of the dictionary can reconstruct the original audio clip by accessing the codewords via the received IDs, modify them as instructed by the modification instructions, further modify the codewords either individually or in groups using the audio profile of the original audio file (also sent by the encoder) and play back a generated sequence of phase corrected codewords and modified codewords as instructed. In exemplary embodiments of the present invention, such modification can extend into neighboring codewords, and can utilize either or both (i) cross correlation based time alignment and (ii) phase continuity between harmonics, to achieve higher fidelity to the original audio clip.

Abstract: Systems and methods are presented for transmitting additional data over preexisting differential COFDM signals by changing the amplitude of the legacy data symbols. In exemplary embodiments of the present invention, additional data capacity can be achieved for a COFDM signal which is completely backwards compatible with existing legacy satellite broadcast communications systems. In exemplary embodiments of the present invention, additional information can be overlaid on a legacy COFDM signal by applying an amplitude offset to the legacy symbols. In exemplary embodiments of the present invention, special receiver processing can be implemented to extract this additional information, which can include performing channel equalization across frequency bins to isolate the amplitude modulated overlay signal. For example, at each FFT symbol time, average power across neighboring active data bins can be used to determine the localized power at the corresponding FFT bins, and a channel inversion can then, for example, be performed on the data bins to restore, as best as possible, the original transmitted symbol amplitude.
