We all know you can’t prove a system is secure and you can’t eliminate bugs. What you can do, is implement the Best Current Practice for security in your IP facility. AMWA are working on defining two BCP-003 specifications to help you do just that.
Arne Bönninghoff from Riedel is our man to take us through what these two BCP specifications mean. He sets the scene by explaining the difference between confidentiality and integrity, between authentication and authorisation. BCP-003-01 deals with establishing trust (identification, integrity and authentication) as well as confidentiality. Whereas BCO-003-02 defines the best practices for authorisation.
Taking these in turn, Arne looks at how TLS works (sometimes synonymous with the old SSL technology). He shows how the certificates are exchanged and identified, highlighting the need for DNS which is recommended as part of EBU TR 1001-1. TLS is all about encryption, so we look at the encryption methods available, also known as HTTPS ciphers. Arne makes the point that out of the possibilities there are only 4 ciphers which are widely supported by all vendors. In summary, BCP-003-01 needs certificates, DNS and internet access to connect to certificate authorities.
BCP-003-02 talks to ensuring that only permitted right computers can interface with the system, for instance to use NMOS IS-04 and IS-05. It describes how tokens can be retrieved, used for access and be validated. Also called IS-10, Arne talks us through the information exchanges in the system and explains how OAuth2 + JWT come in to play. Arne cautions about being anything but ardent about implementing security best practice and concludes saying that the IS- specifications are based on IT standards like HTTP and JSON which are widely used across the IT industry.
Is the industry successfully delivering what we need with SMPTE’s ST 2110 suite of standards? What are the benefits of IP and how can we tackle the difficulties?
In this panel from Broadcast Solutions’ Innovation Day, we hear from 5 vendors understanding their perspectives and plans for the future. Claus Pfeifer from Sony say they have now 60 sites up and running in IP. Lawo’s Phil Myers follows up saying “People know they have to go IP, it’s a matter of when they go IP.”
Whilst this is a positive start, the panel moves on to talking briefly about difficulties implementing SMPTE ST 2110. Jan Eveleens from Riedel points out many of the issues will go as we are waiting for technology to catch up regarding CPUs and bandwidth. We no longer have the same processing issues we used to for audio. Similarly with video, technology will improve and remove many of the challenges. Phil Myers feels that cloud implementation issues are not a large problem at the moment as he sees a move to bring equipment into private clouds rather than public. This way they are doing ‘remote production for buildings’.
After each vendor outlined their future plans for IP, Zoltan highlighted that IP allows NDI to co-exist with ST 2110. Many may want to use 2110 for high end sports, for others NDI fits well. Then panel felt that a concerning area of IP is the worry of how to fix problems. The knowledge level is different from country to country. So vendors not only need to work on education about IP, both for NDI and 2110, but they need to do this in a focussed way for the different markets.
As the panel comes towards the end, Claus feels that the industry started to talk too early about pure technology. “Did not discuss enough about the business benefits.” he explains such as remote production and more efficient use of equipment – avoiding ‘sleeping Capex’. Installing IP makes a lot of sense for large-scale systems. Recently broadcasters have been working at a scale requiring much more than 1024 squared routers roughly where SDI routers top out. But also, these large systems tend to have a life of over 10 years. Faced with SDI development, particularly in routers, is slowing down or stopping, for these long-lived systems it makes much more sense to use IP.
Held a couple of months before SMPTE 2110 was ratified at IBC, this panel discussion with Riedel, Evertz, EVS and Grass Valley looks at the state of SDI and IP: Which technologies are relevant now and which will win in the long run?
The conversation covers these topics and more:
12G Vs 3G SDI
Versions of UHD SDI
When should a vendor implement IP?
Will the future include compression?
How do you handle variable latencies with compression?
With the first all-IP and 12G-SDI OB trucks beginning to hit the road, and an increasing number of broadcast centres implementing comprehensive IP-based or hybrid infrastructures, this discussion will focus on the issue of connectivity and whether it is advantageous to use SDI or IP infrastructures – or indeed hybrid approaches utilising both. This panel discussion discussed the imperatives behind this dramatic technological change, the challenges that it presents, and the probable roadmap for the next few years. There will also be analysis of current industry initiatives such as AIMS and the ways in which these can help smooth the transition.
