    摘要: Disclosed is a system and method for determining output transmission power for radio signal transmission, from an interception transmitter and from an announcement transmitter, respectively, to at least one announcement receiver, wherein each announcement receiver is in a respective motor vehicle, the method comprising: receiving an input signal to be suppressed; determining a first field strength of the input signal, at a first frequency fI, at a position POSR; determining a first transmission power of a first radio signal, intended to be transmitted by the interception transmitter, needed to suppress the input signal at an interception transmission distance; determining a second field strength of at least one of atmospheric noise and the input signal at a second frequency fA, at the position POSR; and determining a second transmission power of second radio signal comprising an announcement to be transmitted by the announcement transmitter to the at least one announcement receiver.

    摘要: Systems and methods are provided for providing content to a receiver. A first broadcaster is configured to broadcast a first content on a channel over an associated first region of signal coverage. A second broadcaster is configured to broadcast a second content, different from the first content, on the channel over an associated second region of signal coverage that overlaps the first region of signal coverage to form a region of overlap. A gateway device is configured to schedule transmission times for the first and second broadcasters, such that a receiver tuned to the channel receives the first and second content as a time divisional multiplexed signal.

    摘要: A system and method supporting over-the-air programming of access device such as, for example, a mobile multimedia handset and a wireless personal digital assistant (PDA) via a broadband access gateway, is disclosed. The broadband access gateway may receive identifying information from the access device via a personal area network and/or a wireless local area network, and may transfer the identifying information to a wide area network or a third party content provider, via a broadband network. The broadband access gateway may enable the registration of the access device with the wide area network, and may receive firmware/software updates and/or provisioning parameters via the broadband network. The gateway may then transfer the firmware/software update and/or provisioning parameters to the access device via the personal area network and/or wireless local area network.

    摘要: A receiver that receives a broadcast signal including service data of a broadcast service and an emergency alert table including an emergency alert message, a first decoder that decodes the service data, a second decoder that decodes the emergency alert table, and a display processor that displays the broadcast service including the decoded service data and emergency alert message in the decoded emergency alert table. The display processor further displays information to notify that an additional content related to the emergency alert message is present, and the display processor further displays the additional content based on a selection of the information by a user. The broadcast signal further includes wake-up information, where a value of the wake-up information is changed from 0 to 1 based on a wake-up call, and the value of the wake-up information is changed from 1 to 2 based on a different wake-up call.

    摘要: A system and method for transmitting the audio component of a performance, such as a movie, to audience members located in the listening area of a venue, such as a movie theater, to improve the quality of the audio experience and reduce problems with other noise activity interfering with the performance. The system and method use the location of the occupied seats, geometry of the venue and the audience density to produce a structured operating envelope that is utilized to more efficiently and effectively broadcast an audio signal, which comprises the audio component of the performance, to individual audience members. The audio signal is received by a smart phone or other electronic device associated with one or more audience members. The audio component is transferred to headphones, ear buds or other devices worn by an audience member and connected, wired or wirelessly, to the electronic device.

    摘要: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for broadcasting a local signal B that corresponds to a coverage hole in a remote signal B. The system includes a first transmitter at a first location and a second transmitter at the first location that transmits local signal B corresponding to remote signal B transmitted from a remote transmitter. The second transmitter broadcasts the local signal B to at least part of a coverage hole in a coverage area of remote signal B. Also disclosed is a method for consolidating allocated wireless spectrum. The method includes identifying a guard band in an allocated band of wireless spectrum, reassigning an existing channel occupying a portion of the allocated band of wireless spectrum to the guard band via selective single frequency network infill to yield a reassigned channel, and freeing the portion of the allocated band of wireless spectrum.
