Descrizione (IT): Processore di streaming con codificatore hardware H.264 per lo streaming in HD tramite i protocolli SRT o RTMP. Il motore hardware di streaming incorporato è stato sviluppato per garantire trasmissioni di qualità professionale sulle piattaforme come YouTube Facebook e Twitter tramite Ethernet o la rete mobile di un telefono 5G o 4G.  Non servono computer costosi né complicati software di streaming. Basta collegare una sorgente video SDI ad esempio uno switcher di produzione o una camera e connettersi a Internet mediante Ethernet o la rete mobile di un telefono. Contemporaneamente si può anche collegare un computer all’uscita webcam USB e usare un altro software di streaming. Web Presenter si configura facilmente grazie all’utility compatibile con Mac e Windows e si connette mediante USB o in remoto tramite Ethernet. Include una porta webcam USB un ingresso 12G-SDI con conversione di standard e monitoraggio tecnico. Vanta anche un’uscita per il monitoraggio con video livelli audio e grafici di andamento.  Web Presenter offre due connessioni USB che operano come semplici webcam in questo modo si può collegare ai computer e lavorare con qualsiasi software video. Il software rileva Web Presenter come una webcam pur essendo un’autentica sorgente video SDI di qualità broadcast con la qualità a piena risoluzione a 1080 HD.  Blackmagic Web Presenter HD rileva il segnale di ingresso HD e lo converte automaticamente in 1080p HD di alta qualità e a basso data rate per poi inviarlo all’hardware di codifica per lo streaming. Ciò permette di mandare in streaming qualsiasi sorgente HD. Blackmagic Web Presenter offre funzioni di ridondanza per garantire trasmissioni ininterrotte. Per connettersi a Internet si può usare sia Ethernet sia la connessione condivisa di un telefono 4G e 5G. Per gestire Web Presenter basta usare i pulsanti e i menù frontali e l’utility inclusa. Oltre a inviare il video ai servizi di streaming Blackmagic Web Presenter funge anche da snodo per collegamenti SDI privati tra studi. ATEM Streaming Bridge è un convertitore video in grado di ricevere un flusso H. 264 da Blackmagic Web Presenter e riconvertirlo in video SDI. Così facendo è possibile inviare il video da un posto all’altro mediante la rete Ethernet locale o al mondo intero con Internet. Questo è possibile perché il processore hardware H. 264 interno decodifica il flusso di Web Presenter.  Infine Blackmagic Web Presenter si rifà al design modulare dei Teranex Mini da poggiare sulla scrivania o installare sul rack. Affianca Blackmagic Web Presenter allo switcher ATEM 1 M/E Constellation HD per allestire una postazione di produzione dal vivo e streaming in una sola unità rack.  La connessione USB frontale permette di collegare il computer per modificare velocemente le impostazioni locali.

Description (EN)

Streaming processor with H.264 hardware encoder for HD streaming via SRT or RTMP protocols. The built-in hardware streaming engine was developed to ensure professional-quality broadcasts on platforms such as YouTube Facebook and Twitter via Ethernet or a 5G or 4G phone's mobile network. You don't need expensive computers or complicated streaming software. Simply connect an SDI video source such as a production switcher or camera and connect to the Internet via Ethernet or a phone's mobile network. At the same time you can also connect a computer to the USB webcam output and use other streaming software. Web Presenter is easily configured thanks to the Mac and Windows compatible utility and connects via USB or remotely via Ethernet. It includes a USB webcam port a 12G-SDI input with standards conversion and technical monitoring. It also boasts a monitoring output with video audio levels and trend graphs. Web Presenter offers two USB connections that act as simple webcams so it can connect to computers and work with any video software. The software detects the Web Presenter as a webcam while being an authentic broadcast quality SDI video source with full 1080 HD resolution quality. Blackmagic Web Presenter HD detects the HD input signal and automatically converts it to high quality low data rate 1080p HD then sends it to the encoding hardware for streaming. This allows you to stream any HD source. Blackmagic Web Presenter offers redundancy features to ensure uninterrupted broadcasts. To connect to the Internet you can use either Ethernet or the shared connection of a 4G and 5G phone. To manage Web Presenter just use the front buttons and menus and the included utility. In addition to sending video to streaming services Blackmagic Web Presenter also serves as a hub for private SDI links between studios. ATEM Streaming Bridge is a video converter that can receive an H. 264 stream from Blackmagic Web Presenter and convert it back to SDI video. By doing this it is possible to send the video from one place to another via the local Ethernet network or to the whole world with the Internet. This is possible because the internal H. 264 hardware processor decodes the Web Presenter stream. Finally Blackmagic Web Presenter draws on the modular design of the Teranex Mini to be placed on the desk or installed on the rack. Pair the Blackmagic Web Presenter with the ATEM 1 M/E Constellation HD switcher to set up a live production and streaming station in a single rack unit. The front USB connection allows you to connect your computer to quickly change local settings.
