BROADCAST TRENDS IN EUROPE Tieline Insider asks Charlie Gawley, Tieline’s VP Sales APAC/EMEA, about the latest technology trends among European broadcasters. Insider: Charlie you visit a lot of European countries and see a lot of broadcast installations, what are the key trends you have noticed over the last year or so? Charlie: During the last 12 months I have noticed a shift throughout Europe to predominantly IP broadcasting. This has been evident for audio distribution applications, and remote outside broadcasts, where reliance on ISDN/E1 circuit switched lines continues to drop throughout the continent. Insider: From the perspective of remote broadcasting, how are broadcasters transitioning into new technologies? Charlie: Most broadcasters are relatively comfortable with IP for live streaming of broadcast content, however they have become more demanding about redundancy strategies over IP networks. Infrastructure does vary from country-to-country, but generally wired and/or wireless IP is able to reliably broadcast from just about anywhere these days. Insider: What sort of redundancy strategies are in play? 6 www.tieline.com
BROADCAST TRENDS IN EUROPE interview with Charlie Gawley Charlie: Even though broadband infrastructure is improving all the time, no two networks are the same. Tieline has employed SmartStream PLUS redundant streaming for many years now and this is a well-established IP redundancy model in the industry. However, I have found several European broadcasters requesting more redundancy to employ more sophisticated and layered approaches to IP backup. That’s why we have developed new firmware with support for up to 3 redundant IP streams, plus a primary stream, so theoretically you can send IP audio over 4 separate networks back to the studio. Insider: What about remote control, is this important in Europe? Charlie: Yes remote control is very important - and I might add it’s by necessity. It’s very evident that broadcasters are covering more sport generally. Therefore, I am increasingly being asked about how Tieline can provide solutions which can be given to announcers and taken to a sports event, festival or wherever, and controlled back at the studio, because there are not enough technical personnel to go to every event. We have this covered nicely with the recently released Cloud Codec Controller, which allows engineers to not only remotely control their IP codecs, but also users of Tieline’s Report-IT Enterprise smartphone app. Insider: What about IP bonding, is this talked about much? Charlie: Absolutely, some broadcasters employ both SmartStream PLUS redundant IP streaming and IP bonding simultaneously. Again, broadcasters are moving away from external boxes that perform bonding and want solutions in a single box, like with Fuse-IP bonding in the Tieline ViA, which can bond of any of up to 7 available IP interfaces. There are two reasons for this, one is that bonding-only solutions can be expensive, and secondly, if everything is handled in the one box then it is simpler to hand to an announcer and say, ‘off you go and broadcast’. There are fewer potential points of failure too. Insider: Are any other redundancy strategies employed by engineers? Charlie: Yes Forward Error Correction is used extensively, and error correction strategies are inherent in Tieline IP codecs, so along with redundant streaming and IP bonding, there are many options to get rock solid audio back to the studio. Insider: Thanks Charlie. Tieline: The Codec Company 7
