Date: Tomorrow, Wednesday December 11th, 9am CET and 5pm CET.
Axon’s series of webinars looking stepping through broadcasting in IP from the very beginnings has been working up through the topics and now comes to managing redundancy within an IP architecture.
Led by Peter Schut, CTO of Axon, he looks at SMPTE ST 2022-7 which is the standard method of seamless switching allowing redundancy in the paths and the streams. But, of course, there are many other ways of creating redundant IP systems including managing redundancy at the network level as well as the device level.
This webinar happens at two times. Once in the morning for europe and once in the afternoon.
Uncompressed audio has been in the IP game a lot longer than uncompressed video. Because of its long history, it’s had chance to create a fair number of formats ahead of the current standard AES67. Since many people were trying to achieve the same thing, we find that some formats are compatible with AES67 – in part, whilst we that others are not compatible.
To navigate this difficult world of compatibility, Axon CTO Peter Schut continues the Broadcast 101 webinar series with this video recorded this month.
Peter starts by explaining the different audio formats available today including Dante, RAVENNA and others and outlines the ways in which they do and don’t interoperate. After spending a couple of minutes summarising each format individually, including the two SMPTE audio formats -30 and -31, he shows a helpful table comparing the,
Timing is next on the list discussing PTP and the way that SMPTE ST 2059 is used then packet time is covered explaining how the RTP payload fits into the equation. This payload directly affects the duration of audio you can fit into a packet. The duration is important in terms of keeping a low latency and is restricted to either 1ms or 125 microseconds by SMPTE ST 2110-30.
Peter finishes up this webinar talking about some further details about the interoperability problems between the formats.
Peter Schut is back in the sixth webinar in Axon’s Broadcast IP 101 series, this time examining timing, namely PTP, for professional essence-over-IP systems such as based on SMPTE ST 2110.
Timing needs to be rock solid in studio settings where many signals are mixed together, so your PTP system needs to be too. SMPTE 2059-2 standardises the use of PTP timecode (IEEE 1588) in broadcast. It’s important to understand how master clocks and slave clocks work, plus there is talk of ‘transparent’ and ‘boundary’ clocks in switches. Getting the architecture right is key remembering that one important different between IP timekeeping and black and burst time keeping is that the communication is two-way.
Peter gives us the benefit of his experience and insight into getting timing right in two sessions, one morning, one evening.
The well-known 2022 and 2110 standards define transportation of video (and other essences). Like SDI-related standards, they don’t describe how to control the path of signals or monitor them. Unlike SDI, however, we expect to know what’s plugged in to our networks (AKA discovery) and then to control the data flow. There are proprietary and open specifications for doing this, including AMWA IS-04, IS-05 and IS-06 which deal with discovery, control and connection management.
In this webinar, CTO Peter Schut describes the lay of the land and how you can implement control and monitoring in an IP infrastructure.
The webinar happens twice. Once at 08:00 GMT (Midnight PT) and once at 16:00 GMT (11am ET).
