AV over IP: From the Ground Up, presented by Brompton Technology CTO Chris Deighton, covers some need-to-know fundamentals of AV over IP and SMPTE 2110, as well as how our next generation SQ200 processing supports the latest resolutions and protocols.
There is significant industry demand for AV over IP and Brompton’s next generation processors support this. It’s fundamentally about sending video but, as Chris Deighton points out, “it is different to baseband video like HDMI, DisplayPort or SDI, and as a result there are definitely some new concepts that are quite important to understand”.
In a new 10-part, bite-sized video series on AV over IP, Chris covers various key fundamentals. He begins the series by deconstructing the term AV over IP to explore its constituent parts.
In Episode 1: What is AV? he explains that, in its simplest sense, AV is audio and video and turns his focus on video, which he deconstructs too – into things like frames, pixels, channels and bits. While in Episode 2: What is IP?, Chris provides some context to IP in his explanation of packet-switched networking.
In Episode 3: Why AV over IP?, Chris looks at the advantages of bringing the two together, also comparing IP to baseband to provide an informative overview of why one might be better than the other.
Getting into some of the practicalities in Episode 4: Sending Video Data Over IP, Chris looks at how video data (pixels) is sent over a network as well as some of the standards suited to interconnecting between video devices, including ST 2110, NMOS and IPMX.
In Episode 5: Sending Video Timing Over IP, Chris explains that while in baseband video genlock is used to synchronise frame rate and phase across multiple devices, it’s done differently with IP. He shows how ST 2110 splits this into two parts.
As Chris points out in Episode 6: Connecting Senders and Receivers, the receiver must have enough detail not only to interpret the sender’s signals, but also to find those signals in the first place. He looks at what kind of detail that might be and the protocol specified by SMPTE 2110.
In Episode 7: ST 2110 Systems & Management, Chris looks at managing an ST 2110 system when there are multiple video streams on a network. Setting it up manually is a possibility but there is another, better way of doing it – using a management protocol called NMOS.
Getting to the heart of the matter in Episode 8: Improving the User Experience, Chris imagines the ideal scenario of any two media devices simply working together and takes a closer look at IPMX.
The launch of Brompton’s new generation LED processing technology introduces support for best-in-class AV over IP and in Episode 9: AVoIP on SQ200, Chris looks at the specifics of what this means.
Finally, in the Episode 10: Wrap-Up, Chris provides a recap of what’s covered in the series, which doubles as a handy outline of the technologies required to make AV over IP work.
