IP convergence state of the art and beyond

IP convergence state of the art and beyond

We are currently going through a transition where many things are disjointed. When we changed from the analogue world to the digital world in video, we moved from PAL/NTSC/PAL/SECAM to SDI, a format that included a transport interface. It was a simple change, in part, because we still talk about an environment where everything was very similar and did not entail such a significant change like migrating to an IP world. Now everything is seasoned with 4K and HDR, which leads to a certain lack of definition in the market

The question is not “IP, yes or no?” because we already know that IP is the next step forward from a technological perspective. Perhaps now it is the ideal moment to call our market a video environment instead of a broadcast environment, without losing the perspective of the high quality and great service availability that characterise it. These two factors are imperative when assessing IP. We are talking about a technology that will bring great advantages, perhaps the largest will be the possibility of physically separating different production points despite them being connected at a logical level. We will have the possibility of taking cameras to one place and still carry out the production somewhere else. They will be supported by a CPD, and this topology will contribute towards having redundant systems or sharing resources. A control will be able to work interchangeably for one or another studio straightforwardly; a true revolution.



Nowadays, we lack the necessary standards to bring about the convergence. As we were saying, we are also getting accustomed to 4K/UHD, and IP interfaces are not capable of handling this information as is expected of them. 10 Gbps do not fit unless we use some sort of compression but in a production, we need to manage these types of flows natively, which can only be done with a 12 Gbps bandwidth, where the flows we want to work with in future, do fit. Therefore, working in 12G is essential, and to this end, IP interfaces must take one more step; something we think will not take too long. This is the necessary factor for the manufacturers to develop equipment with stability. At the end of the day, we still depend very much on hardware. This is why it is vital there be a standard and that manufacturers/developers implement it in their systems and solutions. In this respect, future NAB and IBC should shed a lot of light. In these trade fairs, we will be able to see the level of implementation the manufacturers have in working with each other. This is fundamental. Engineers and technicians are increasingly set on building their own solutions, escaping from having to engage with one single manufacturer or developer.

Despite this, we are at a moment in time where each manufacturer is committed to specific solutions, despite them seeking approximation between them. The standard SMPTE 2022-6 has been achieved for encapsulation of SDI over IP, but this is an intermediate point towards the true transition to native IP, where the streams of audio, video or metadata signals will travel separately. In this last aspect, manufacturers are getting ever closer, and the SMPTE already has a working group for its standardisation (SMPTE 2110).
