JVC GY-HC500, GY-HC550 ja GY-HC900 kamerat saivat SRT IP-video siirron tuen

JVC julkaisi Connected Cam päivityksen 500 ja 900 sarjan kameroille, mikä sisältää Secure Reliable Transport (SRT) IP -siirron tuen max. HD1920x1080 50/60p signaalille. SRT -protokolla on samankaltainen kuin Newtek NDI HX -protokolla eli sen kautta verkon kautta saadaan video siirrettyä kohtuullisen pienellä latenssilla. Latenssi on säädettävissä verkon kapasiteetin mukaan mutta on yleensä 3-5ruutua riippuen latenssiasetuksista. SRT:tä tukevat esim. OBS, mikseriohjelmistot Tele Stream Wirecast ja VMix ja lisäksi on olemssa SDI- ja HDMI muuntimia. Myös SRT to HDMI/SDI dekoodereita on markkinoilla. Magewell NDI ja h26x dekooderit sisältävät SRT-tuen. SRT on open sourcea ja sitä kehitetään aktiivisesti. Esim. RTMP protokollaa ei enää kehitetä. Lisätietoa SRT:stä

JVC lehdistötiedote

1st September 2020 – JVCKENWOOD furthers its commitment to providing the video production industry with the highest quality streaming solutions in a complete, plug-and-play package with its latest CONNECTED CAM firmware update. Using the open source Secure Reliable Transport (SRT) technology, JVC adds Forward Error Correction (FEC) and Stream Identifier (ID) to its 500 Series and 900 Series CONNECTED CAM cameras. The new firmware reinforces JVC’s standing in the industry as the leading provider of high-quality end-to-end streaming-capable camera solutions.

“As the first camera manufacturer to provide streaming direct from the camera itself, JVC offers the complete solution beyond just the camera,” says John Kelly, General Manager, EMEA Professional Business Solutions. “The whole CONNECTED CAM system, with compatible decoders and switchers and SRT’s open source technology, provides a truly plug-and-play streaming ecosystem that doesn’t require expensive backpacks. It’s ideal for IP-based productions, deliving hiqh-quality, reliable images.”

The JVC CONNECTED CAM range, which also includes its SRT-enabled BR-DE900 decoder, BR-EN900 encoder and the KM-IP6000 versatile live production and streaming system, is an easy to use streaming solution that meets a variety of budgets. The system’s cross-compatibility between brands also means that users can incorporate the latest streaming video capabilities with their existing streaming studio equipment.

Adding FEC to JVC’s CONNECTED CAM models allows for redundant data stream packet loss recovery, meaning that data loss can be corrected before the video must buffer, while Stream ID makes it possible for multiple cameras to stream directly to one device. The company has also incorporated VITC (vertical interval time code) and LTC (longitudinal time code) functions with this latest update; together with the implemented NTP (Network Time Protocol) function, these are ideal for synchronising multiple remote cameras during the live production and streaming of events, such as concerts, sports, ceremonies and conferences.
