    Default Lnb ip

    Asta suna interesant.

    SES, Inverto, Abilis and MaxLinear Revolutionize Satellite TV

    New IP-LNB delivers satellite broadcast content to TVs, tablets, smartphones and PCs connected to the home IP network.

    LUXEMBOURG – SES Industry Days Conference - April 18, 2013

    – SES (NYSE Euronext Paris and Luxembourg Stock Exchange: SESG), Inverto, Abilis and MaxLinear Inc. (NYSE: MXL) today announced that they have been jointly designing an essential component for cost-effective IP distribution of satellite television to the home

    – the first low-noise block down-converter (LNB) that will incorporate eight-channel satellite-to-IP bridging technology.
    The IP-LNB is a prototype device that will deliver eight concurrent channels from any of the transponders of a satellite orbital position. These channels may be forwarded via IP unicast or multicast to fixed and portable devices. Satellite signals will be distributed via Ethernet, power-line communications (PLC) or a Wi-Fi local area network (LAN). The technology can be used for free-to-air (FTA) or pay TV applications.

    “The IP-LNB will give satellite television providers and consumers new options for distributing unmatched quality satellite television to multiple TVs, computers and tablets over IP at the lowest cost,” said Thomas Wrede, Vice President of SES Reception Systems. “When we committed ourselves to making SAT>IP an open standard, we envisioned this type of innovation. It is exciting to see it now come to fruition.”
    The LNB is a crucial element of a satellite system, receiving signals collected by the satellite dish, amplifying and converting them to intermediate frequencies to be carried to the set-top box (STB).
    By locating the satellite reception and the IP bridging functions in the antenna the IP-LNB will enable satellite content distribution to the home over a single Ethernet cable. The IP-LNB may be powered over that same cable through Power over Ethernet (PoE) technology. This technology greatly reduces the overall system cost and power consumption.

    For the first time, the satellite signal is sampled digitally directly at the antenna. This technology will also make satellite spectrum data and other link-quality metrics accessible over the LAN. This will greatly simplify the dish installation and enable remote monitoring from the LAN.
    Designing such a novel LNB requires significant advances in satellite chipset and real-time IP streaming software technology in order to meet the unique system requirements on the size, power consumption, long-term reliability and price point required for a commercially viable outdoor unit (ODU).
    The new device will combine SES’ SAT>IP protocol innovations, MaxLinear’s Full-Spectrum Capture™ (FSC™) DVB-S2 receiver IC, Abilis’ TB101 Broadcast to Broadband Bridge™ (B3™) SoC, and Inverto’s software stacks and a new high-performance LNB product design. Together, these technologies have produced a compact, cost effective and low-power eight-channel IP-LNB.
    Availability
    The IP-LNB technology will be demonstrated at SES’ Industry Days conference being held on April 18 and 19 in Luxembourg. The parties are currently engaging with key customers to characterize various parameters for a first commercial IP-LNB product and its deployment schedule.

    Pentru hobbysti exista dreambox vtuner si in mod comercial Nessie DVB.

    O greseala de exprimare as spune: Semnalul digital nu poate sa fie sampled la antena. Sampled in ce anume ?
    Aceasta se va face tot prin intermediul unui tuner si demodulator, software pump dupa care se obtine IP feed.

    Mie imi pare ca nu e vorba de transformar semnalul modulat in flux pe ip.
    In caracteristicile dispozitivului pe care il propun oamenii include deja tunerul.

    "IP-LNB Key Features

    10.7-12.75 GHz Ku-band RF, compliant to SES requirements
    8-channel Full-Spectrum Capture™ DVB-S2 single-chip receiver
    Broadcast to Broadband Bridge™ SoC
    IP and real-time SAT>IP streaming software stacks and protocols.
    Gigabit Ethernet LAN connectivity, Wake-on-LAN
    Power-over-Ethernet Type I, less than 10W for 8-channel operation
    Remote spectrum, temperature and PHY metrics monitoring
    SW upgradeable over Ethernet and over satellite broadcast"

    Eu cred ca vor si ei sa faca un ban cinstit cu aceeasi tehnologie.
    Aceasta caracteristica spune totul - Broadcast to Broadband Bridge™ SoC
    SoC deobicei este un chip specializat care poate fi un simplu CPU sau un convertor.
    Se transforma semnalul modulat in IP streaming.
    Dar sa nu ne dam cu presupusul - te rog sa postezi cum functioneaza dupa ce il cumperi
