Andy Rayner from Nevion looks at using SMPTE ST 2110 on a Wide Area Network (WAN).
While using ST 2110 is a much discussed topic in the studio or within a building, there are extra difficulties in putting it between buildings, cities and countries with some saying it shouldn’t even be done. Here, Andy examines how you can do it whilst acknowledging the industry still has some decisions to make.
John Mailhot from Imagine Communications discusses what ‘Full Stack’ means for video over IP. The SMPTE 2110 suite of standards is mainly about the transport of essences – but how to you simply plug in some equipment and get going? You need standards which discover and register the new device, you need timing to synchronise devices. It’s a whole ecosystem.
John walks us through the data flows (and workflows) necessary when you plug new 2110 kit in and we quickly discover there is more depth than we imagined.
John also discusses how DHCP can give you more than just IP addresses.
Covering IS-04, IS-05, PTP/SMPTE 2059, ST 2110 and IEE 802.1AB (LLDP). This is a very practical video. Why? Because understanding all this is key to diagnosis and troubleshooting.
Paul Briscoe explains PTP from the basics taking us through the reasons for using it and how it’s applied to the ST 2110 which to carries uncompressed video, audio and metadata.
The ST 2110 standard brings with it an entirely new way to establish system timing, through use of IEEE-1588 PTP and SMPTE ST2059. This method is native to the IP domain and to the RTP transport and media synchronization used by 2110 but also provides virtualized legacy timing capability.
Paul discusses
• The considerations in system timing using ST2110, including those which include SDI elements.
• How PTP delivers precision time across an IP network
• How ST2059 uses PTP to virtualize any reference signal.
• The synchronization mechanisms of ST2110 including transport timestamps and media clocks
• How streams are synchronized among each other and how they interoperate with PTP
• How timing of SDI and AES3 signals is harmonized with ST2110 streams.
• Router switchpoint timing and latency considerations.
