Abstract: A method and apparatus 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. 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. 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.

Abstract: Methods and apparatuses provide personalized radio by outputting selected songs from multiple channels from one or more source streams. Users can specify favorite channels for building their personal playlists, or multiple default playlist channels can be provided by genre or other criteria. User like/dislike inputs via the radio receiver generate filter data used to search all channels for matches or block songs from playback. Filter data can also be based on virtual DJ recommendations. Channel searching for matches involves monitoring real-time song and artist labels or other metadata for all channels carried in a separate data channel. Personalization can also be provided by using filter data to select content from a mixed channel comprising content from a selected group of channels. Connectivity options and web interfaces are provided to facilitate transfer and sharing of customization parameters for personalized radio configuration.

Abstract: A system is provided for generating a remapped audio stream at digital audio broadcast radios from a first audio stream using content insertion to allow tiered subscription services. A remapped audio stream is rebranded by extracting segments from the first audio stream relating to channel identification segments and disk jockey talking segments and replacing them with stored audio items (e.g., commercials, different channel identification segments and different disk jockey talking segments). Stored audio items for insertion are broadcast to the radios with messages for controlling the scheduling of insertion at the radios, and the storage and deletion of these audio segments at the radios. Stored audio items and messages can be sent using a different, localized broadcast system from that used to transmit the source audio stream to permit market-specific commercial insertion. Group file format for delivery permits intermittently used radios to receive the stored audio items and messages.

Abstract: A communication system (100) encodes and decodes information utilizing at least four modulation levels for transmitting the information as symbols representing symbol bits in symbol bit positions. At least one of the symbol bit positions exhibits an error rate higher than that of another of the positions. A processor (204) encodes (702) the information into an even number of code words and transmits the code words as an interleaved data stream. The processor (204) rearranges (706, 708) the transmission order of the code word bits in a predetermined way to form a modified transmission order such that the code words are transmitted (710) with substantially equal error rates. A receiver (110) receives and demodulates (712) the interleaved data stream to derive the code word bits, and then reorders (714, 716) the code word bits to undo bit modifications resulting from the modified transmission order, thereby restoring the code words. The receiver then decodes the code words to recover the information.
