Evident Productions recently provided consulting and infrastructure design for the 66th FIFA World Congress in Mexico City, specifying the SSL Network I/O: SDI as the core component in the crucial broadcast infrastructure for embedding, de-embedding, and distribution, using a Dante Audio-Over-IP network as the source.

The SSL Network I/O: SDI has eight 3G-SDI paths with embedders and de-embedders for 16 audio channels, and provides bidirectional bridging between three formats simultaneously: embedded SDI Audio, Dante, and MADI (2 x optical, 1 x coax I/O).

Features include channel-by-channel routing (via the control application), full broadcast spec redundancy, and sample rate conversion in the audio path to and from SDI.

Evident Productions founder Peter Blue was involved in significant system improvements for the FIFA Congress itself, providing the feeds to over 20 international broadcast networks covering the event. The audio source was taken from the Dante Break Out connections on the Lake LM26 processors at FOH, and contained six different translations plus the main left and right house channels.

"When I saw the SSL box I thought 'wait a minute, this fits the bill for everything’”, said Blue. “It does both the embedding and the de-embedding for different protocols simultaneously, and it's taking care of the bridging from the audio side of things.

“The real game changer for us though was working with multiple video formats simultaneously. When we found out that we could embed audio in 1080i, 720p, and 480i, plus de-embed audio coming into us on any format on the HDSDI stream, all at the same time, in the same device, that was the key point in our decision to specify the Network I/O SDI for this event, and to also make the investment in our inventory."

The Network I/O: SDI was connected to the redundant Dante network and that audio was embedded into several video formats and passed onto the broadcasters. "Inside the Network I/O we were creating four different basic feeds," Blue added. "The house monitor and a broadcaster world view in three different flavours - 1080i, 720p, and 480i - just so that the trucks and uplinks could easily convert specifically for their own needs.

"The reason we did that on our side rather than just leaving it to the broadcast trucks was because audio delay can be much more easily resolved if you deal with it in the head part of the system, especially with a lot of spoken word and house feeds to deal with. As a result we had no delay problems whatsoever and the broadcaster didn’t have to worry about timing issues at the truck."

Blue noted that as well as the extensive local redundancy measures in the Network I/O: SDI, the multi-format (MADI fibre and Dante) I/O options on the box can help provide another level of whole-system redundancy simply by connecting both to the source.

Overall, Blue was overjoyed with the Network I/O's performance on its first outing with Evident Productions. "It's a device that is much more capable than I think most people realise. Its versatility is what puts it up there and is the reason why we've invested in one. It's beyond any other individual product out there at the moment.”
