Abstract: A sending device having a processing device and a plurality of transmitters performs a method for providing spatially selectable communications using deconstructed and delayed data streams. The method includes receiving a data stream, an indication of a target point for the data stream, and a target volume around the target point. The method further includes deconstructing the data stream into a plurality of data substreams and, based on a spatial relationship between a corresponding transmitter and the target point, determining a transmitter delay for each transmitter. Moreover, the method further includes determining, based on the target volume, a data interval spacing to apply between each data substream at transmission. In addition, the method includes sending, from the transmitters, the corresponding data substreams using the corresponding transmitter delays and the data interval spacing that confine reconstruction of the data substreams back into the data stream within the target volume.

Abstract: Systems and methods are presented for improving the ability to withstand slow speed mute via diversity transmission while avoiding loss in link level margin. In exemplary embodiments of the present invention, systems and methods are presented for improving resistance to slow speed muting by employing transmit diversity where a second signal is not a replica of the original signal. The second signal can be generated, for example, by using only a COFDM FFT bin that contained the cluster sync bit while setting all other bins to zero. That is, only the spectral portion of interest of the COFDM signal need be utilized. In such exemplary embodiments, the same frequency and time delay offset can be used as in current systems and methods, except that the replica COFDM signal can, for example, consist of only one populated FFT bin.

Abstract: A transmitter apparatus at a base station transmits program information using a plurality of carriers with at least some of the carriers having different transmit power levels. The carrier associated with the highest transmit power level conveys broadcast information carrying basic program information. A carrier associated with a lower power level conveys broadcast information including enhancement information and/or additional content. The enhancement information and/or additional content may include a higher level of video and/or audio resolution, additional video and/or audio content, support for additional languages, a text stream, and/or advertisements. A wireless terminal tunes, receives and processes the broadcast information. A wireless terminal can recover different levels of resolution of a broadcast program, e.g., a digital video broadcast program, and/or different amounts of additional content, depending upon which carriers are being used.
