摘要： A transmitter network is provided with at least two transmitters which transmit in a same frequency range. In a unicast-transmission mode of the transmitter, the transmitters transmit unicast information packets (UC) in subsequent first time intervals. The at least two transmitters further simultaneously transmit in a broadcast mode or multicast mode, respectively, broadcast- or multicast information (BC/MC) in second time intervals that lie in between first time intervals, the broadcast information or multicast information, respectively, transmitted by the transmitters in a second time interval being substantially equal and being transmitted by the transmitters substantially time synchronous. The invention also relates to a transmitter and a receiver in the transmitter network.

摘要： A receiver arrangement for receiving a wirelessly transmitted HF transmission signal includes a first conversion unit for converting the HF transmission signal into a baseband information signal. Furthermore, an extraction unit is provided for extracting IQ data from the baseband information signal. A second conversion unit converts the IQ data into a further transmission signal. Additionally, a transmitter is provided for wirelessly transmitting the further transmission signal to a consumer electronics receiver unit. For normal reception of the HF transmission signal, the consumer electronics receiver unit is provided with a first antenna arrangement for receiving the HF transmission signal, and further includes a first signal processing stage for converting the HF transmission signal into IQ data, which are comprised in the HF transmission signal, and a second signal conversion stage for processing the IQ data into an output information signal of the consumer electronics receiver unit.

摘要： A transmission apparatus for wireless transmission of an MPEG-TS (Transport Stream) compatible data stream, according to the Wi-Fi Display Technical Specification of the Wi-Fi Alliance, e.g., in the Version 1.1.0 (Miracast) to a receiver apparatus. The transmission apparatus is provided with a terminal for receiving an MPEG-TS compatible data stream, and is further adapted to wirelessly transmit a first IP address characterizing the transmission apparatus to a receiver apparatus according to the Wi-Fi Display Technical Specification of the Wi-Fi Alliance, e.g., in the Version 1.1.0 (Miracast). The transmission apparatus is also adapted to combine the first IP address with the MPEG TS compatible data stream before wireless transmission to the receiver apparatus. The transmission apparatus is further adapted to allow the receiver apparatus to receive an external IP data stream from an external signal source, and is adapted to wirelessly transmit a second address to the receiver apparatus, the second address characterizing the external signal source. A receiver apparatus according to the Wi-Fi Display Technical Specification of the Wi-Fi Alliance, e.g., in the Version 1.1.0 (Miracast), is provided for receiving the external IP data stream.

摘要： FDM based broadcast transmitter arrangement for transmitting a digital audio/video information signal, wherein an encoded version of the digital audio/video information signal is encapsulated in a network layer encapsulation step in accordance with DAB, DVB-T or DVB-T2 to obtain a network layer information signal. The network layer information signal is then converted in a Data Link Layer conversion step to obtain a Data Link Layer information signal, which is subjected in a Physical Layer conversion step to obtain a broadcast information transmission signal.

摘要： A transmitter for transmitting a data transmission signal in a reception area is provided with an input for receiving an information signal (IS) to be transmitted, a coding—and/or modulation unit for coding and/or modulating the information signal with a certain coding—and/or modulation scheme into the data transmission signal, and an output for supplying the data transmission signal, and an output for supplying the data transmission signal. In accordance with the invention, the coding—and/or modulation unit is adapted to code and/or modulate the information signal with n different coding—and/or modulation schemes (n≥2), and further is adapted to transmit an additional information signal by changing between these n coding—and/or modulation schemes. The invention also relates to a receiver for receiving the data transmission signal transmitted by the transmitter.
