摘要： A method and apparatus are provided for generating a personalized radio channel playlist by time division multiplexing songs from multiple received channels from one or more broadcast source streams in a queue. Users can specify favorite channels for building their personal playlists, or multiple default playlist channels can be provided by genre. Navigation tools permit users to see upcoming songs in their playlist queue and skip ahead and backward. Thumbs up/down buttons on the radio receiver permit entering a song or artist being played back into a favorites list that is used to search all channels for matches or a banned list used to block songs from future playlists. If matches are found, the channel carrying the favorite is extracted and added to the playlist. Channel searching for matches involves monitoring real-time song and artist labels for all channels carried in a separate data channel (e.g., Broadcast Information Channel (BIC)). Segments on the playlist are dynamically truncated to reduce the average time each segment is played to facilitate preview of playlist segments. Preview times can vary depending on the size of the playlist or number of channels used. During a preview of a segment, users can opt to listen to the full song or back up in the playlist to listen to a previous song. Connectivity options and web interfaces are provided to facilitate transfer and sharing of customization parameters for personalized radio configuration.

摘要： A satellite digital audio radio service multipoint distribution system and method. The system comprises a satellite antenna and a satellite receiver for receiving a satellite digital audio radio signal and distributing a converted signal in response thereto. The distributed signal is received by plural receivers each of which provides a respective output signal in response thereto. In the best mode, the satellite receiver is a terrestrial repeater. The repeater decodes a stream of data received from the satellite and recodes the stream using a satellite radio terrestrial broadcast format. In the best mode, the signal is an intermediate frequency signal in the XM radio, multi-carrier modulation format. The recoded signal is rebroadcast by the repeater via a distribution network and received by a plurality of intermediate frequency (IF) receivers. The distribution system may be wireless, cable, or fiber optic. In the illustrative embodiment, the IF receivers are modified conventional satellite digital audio service receivers. A user interface is provided for each IF receiver to allow for channel selection and audio processing.

摘要： A method and apparatus encode a source data stream via convolutional encoding. One or more encoded data streams are interleaved and transmitted on one or more transmission channels. Data groups generated via convolutional encoding are interleaved via time-interleaving functions to disperse selected bits within puncture groups of the data groups, bits in between data groups, and bits in selected sets of data groups to facilitate reconstruction of the source data stream from at least a portion of the interleaved data stream received on at least one transmission channel. The time-interleaving functions are selected to facilitate reconstruction of the source data stream from one transmission channel following continuous blockage. Subsets of bits of puncture groups are selected to allow reconstruction of the source data stream from the transmission channels using a minimum number of subsets. Multiple combinations of subsets can be received via two or more transmission channels to reconstruct the source data stream following blockage of one channel. Decoding is performed via a Viterbi decoder.

摘要： A method and apparatus for communicating geographic specific services to a receiver in a satellite communications network by utilizing location identification information included in a composite signal transmitted by a terrestrial repeater. A terrestrial repeater receives from a satellite a composite signal comprising a plurality of time-division multiplexed (TDM) data channels and retransmits the composite signal with a unique transmitter identification number which indicates the identity of the repeater. Upon reception of the composite signal from the terrestrial repeater, the receiver determines the current geographical location of the receiver based on the transmitter identification number. The receiver then compares the current location of the receiver to header information carried in the data channels to select information in the data channels is targeted to the geographical location of the receiver. The receiver then provides the selected information to a user of the receiver so that user may access services directed to audiences in the geographic location of the receiver.

摘要： A method of interleaving data for transmission is provided wherein first and second interleaving patterns for arranging data symbols in a source data stream into first and second transmitted data streams are selected. Each of said data symbols has at least one bit. The first and second transmitted data streams are transmitted substantially simultaneously on separate transmission channels to at least one receiver. The first and second patterns are used to transmit the data symbols in the source data stream in a different order on the respective transmission channels to maximize recovery of the source data stream when the transmission channels are blocked. The selected interleaving patterns can involve reordering the data symbols throughout the first and second transmitted data streams using different reordering criteria. The reordering criteria can vary on a frame-by-frame basis if the source data stream is time division multiplexed. Complementary data can be sent on respective transmission channels.
