Rohde & Schwarz’ GMIT… Packing A Lot Of Real Estate Onto A Single Screen (SatBroadcasting™—Codec)

[SatNews] The GMIT BMM-810 with HEVC support is now available from GMIT GmbH, a Rohde & Schwarz subsidiary—the company has been developing products and solutions for broadcasters since 2007. The new video codec saves up to 50 percent on bandwidth, making it a most appealing solution for multiscreen services as well as for transmitting high-resolution broadcast programs. To provide operators with the best possible support during implementation, GMIT uses technology developed by the Fraunhofer Heinrich Hertz Institute, enabling the BMM-810 software to deliver the utmost in quality and compliance with standards.

Regardless of the codecs used, the multiviewer displays up to 36 broadcast or multiscreen programs on one screen, providing operating staff with a good overview of the state and quality of all programs. Content errors such as still images and audio silence as well as general decoding errors are detected automatically and displayed, and are also reported to a master management system via SNMP. Errors and quality degradation in compression or transmission are, therefore, identified more quickly and reliably.

The GMIT BMM-810 is equipped with common broadcast interfaces such as TS over IP, ASI and SDI for the input interfaces. The HLS, RTMP, HDS and HSS protocols are supported for multiscreen applications; these protocols can be monitored both in the return reception path and when they are uploaded to a CDN server. The BMM-810 supports mixed operation between broadcast and multiscreen programs, offering operating staff systematic monitoring of all transmitted programs.

All programs are combined in a mosaic view after reception. The mosaic picture is output via a DVI interface or, as an option, via a re-encoded IP stream in full HD resolution. This option eliminates the need for expensive DVI signal distribution and makes it possible to bridge long paths to the screen with an IP connection. A proprietary, highly optimized rendering engine is used for visualization, ensuring that all programs are played back fluidly even when the system is running at full capacity. In addition to video and audio bars, the BMM-810 optionally displays a wide range of program-specific auxiliary information, providing an overview of the state of all program components.
