Mediaproxy, the global standard for software-based IP compliance solutions, is to highlight its recently acquired A3SA certification on booth 1243 at NAB Show New York, 9-10 October at the Javits Center, New York City. The company will demonstrate its full range of compliance monitoring and multiviewer systems, which now provide decryption for ATSC 3.0-based broadcasts being used in the US for NextGen TV.
Mediaproxy announced during August that it is now certified by the ATSC (Advanced Television Systems Committee) 3.0 Security Authority (A3SA) to decrypt ATSC 3.0 streams as part of the LogServer and Monwall product ranges. This gives broadcasters a comprehensive set of software-based tools to monitor and analyze ATSC 3.0 streams without the need for bespoke hardware devices.
The introduction of A3SA security protocols into the LogServer logging and monitoring engine provides broadcasters with a cost-effective option allowing them to monitor both encrypted to-air and off-air signals. For to-air and hand-off applications, an on-premises LogServer system is able to simply take the encrypted STLTP (Studio to Transmitter Link Transport Protocol) output of the packager directly from the stream. This guarantees confidence in what is sent to the transmitter straight from the local IP network.
In off-air monitoring situations it is possible to use inexpensive and familiar integrated receiver/decoders (IRDs) that do not provide decryption but do have outputs of the encrypted IP streams through DASH/ROUTE (Dynamic Adaptive Streaming over HTTP/Real-time Object delivery over Unidirectional Transport) or the recently approved ALP (A/330, Link-Layer Protocol). This enables ATSC 3.0 compliance on IRDs for streaming platforms such as HDHomeRun, with LogServer handling the DRM aspects for all channel sources.
The new ATSC 3.0 security feature is also available on Mediaproxy s ever-expanding Monwall multiviewer, which accommodates low-latency monitoring of both encrypted outgoing and return signals. Alongside the features on Monwall and LogServer, Mediaproxy has developed an extended toolset for advanced IP packet and table analysis of live broadcast streams or PCAP (packet) captures, which can be accessed via easy-to-use user interfaces.
"We are excited to be debuting LogServer and Monwall with the recently acquired A3SA certification at NAB Show New York," comments Mediaproxy chief executive Erik Otto. "Recent figures show that NextGen TV is now reaching 75 percent of US television households so broadcasters need to be aware of ways they can efficiently and cost-effectively monitor and decrypt ATSC 3.0 streams. This is an important advance for Mediaproxy and NAB Show New York is the ideal place to showcase it."
