  2. Block upconverter - Wikipedia

    en.wikipedia.org/wiki/Block_upconverter

    A block upconverter (BUC) is used in the transmission of satellite signals. It converts a band of frequencies from a lower frequency to a higher frequency. Modern BUCs convert from the L band to K u band, C band and K a band. Older BUCs convert from a 70 MHz intermediate frequency (IF) to K u band or C band.

    The working frequency band for HRPT is L Band at 1.670–1.710 GHz and the modulation type isBPSK. [2] On NOAA KLM satellites the transmission power is 6.35 Watts, or 38.03 dBm. [ 3 ] The METOP-A satellite broadcasts with a bandwidth of 4.5 MHz, these use QPSK and AHRPT.

    Parus (Russian: Парус meaning Sail), also Tsyklon-B or Tsiklon-B (Russian: Циклон-Б meaning Cyclone-B) and Tsikada-M (Russian: Цикада-М meaning Cicada-M), [1] GRAU index 11F627, was a Russian, previously Soviet satellite constellation used for communication and navigation.

  6. Asynchronous serial interface - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_serial_interface

    The ASI output of a DVB Integrated Receiver/Decoder (IRD). It carries the entire MPEG transport stream being received from a DVB satellite feed entering the RF input (far left side in picture). Asynchronous Serial Interface, or ASI, is a method of carrying an MPEG Transport Stream over 75-ohm copper coaxial cable or optical fiber. [1]

  7. Multichannel multipoint distribution service - Wikipedia

    en.wikipedia.org/wiki/Multichannel_Multipoint...

    The antenna is attached to a down-converter or transceiver to receive and transmit the microwave signal and convert them to frequencies compatible with standard TV tuners (much like on satellite dishes where the signals are converted down to frequencies more compatible with standard TV coaxial cabling), some antennas use an integrated down ...

  8. Satellite subcarrier audio - Wikipedia

    en.wikipedia.org/wiki/Satellite_subcarrier_audio

    Satellite subcarrier audio is audio transmitted by way of satellite that uses a separate analog or digital signal carried on a main radio transmission (usually video) on a specific satellite transponder. More technically, it is an already-modulated signal, which is then modulated into another signal of higher frequency and bandwidth.

  9. Sat-IP - Wikipedia

    en.wikipedia.org/wiki/Sat-IP

    Conventional satellite TV reception systems convert the received transmissions to an intermediate frequency (IF) for distribution via dedicated coaxial cables to one or more satellite tuners and demodulators in set-top boxes. SAT>IP allows the satellite TV distribution to share a data network and enables display and viewing of the signals on ...
