Medal Ceremonies Arena

The international signal from the medal ceremonies arena at the University square in downtown Oslo will be produced with 8 cameras. The signal will be provided by one Flyaway production unit located in cabins.

There will be a Mixed Zone with dedicated positions and a common ENG area, and a studio position for NRK domestic. There will be no commentary positions on-site, but the ceremonies can be commented off-tube in Holmenkollen.

The signal from the University square will be transmitted to IBC in Holmenkollen via fibre optic cables.

RTV Compound

There are 3 broadcast compounds:

1. Main RTV compound – IBC

Compound for rights holders’ and Host Broadcaster OB vans and support vans/auxiliary vehicles is located next to the IBC.

Only RTV accredited personnel have access to the IBC and compound. There is no ENG parking in the compound.

IBC and RTV facilities and services are available for RHBs from 26 February to 14 March.

2. Holmenkollen Biathlon Arena

The compound located in the tunnel under the arena will accommodate NRK HB OB vans and auxiliary vans.

3. Medal awards ceremonies, University Plaza

Located in front of the University building next to the NRK studio. The compound will only give space for NRK Host production and technical cabins.

TV and Radio international signals produced in each location will be transmitted uncompressed to the IBC through fibre optic cables.

IBC Operations

The Host Broadcaster Master Control Room is located on level 1 in the IBC building B. The MCR will be the international gateway during the championships and the point where on-site broadcasters can pick up the Host Broadcaster signals.

EBU network operational staff will be positioned together with Host Broadcaster personnel for further distribution of the signals.

Isolated feeds from Host Broadcaster cameras booked for unilateral use will be delivered in the MCR. Also, 3 beauty cameras are available.

Power

Strømmast vinter

Both technical power and domestic power for RHB and IBC will be available at RHB/IBC positions as described in the Rate Card.

The power will be supplied through Hafslund’s distribution system. There are two separate supply lines for the power to Holmenkollen. The domestic power will be backed up by diesel generators after a short interruption.

In every technical area, broadcasters will be provided with a single backed-up and uninterrupted power supply to prevent any hum or disruption.

Note: A power failure test will take place prior in Holmenkollen on Tuesday 1 March at 16:00 .

Specs

230V/400V, 1 or 3 phases, 50 Hz
230V Single phase / 16A Schuko / CEE (32A and 63A Single phase on demand)
3 phases+ N / 16A, 32A, 63A, 125A CEE

Grounding

The network for the broadcast areas will be built in TN-C-S 230V/400V, with access to chassis grounding for vans etc.

Uninterrupted Power Supply (UPS)

The UPS system uses stored kinetic energy to bridge the diesel engine start time when there is a utility power failure. It is a battery-free concept. The system is line-interactive and runs in parallel with the utility power. Both RHB and IBC will be fed from multiple distributing panels located in the compound, OB vans and SNGs in the compound, as well as the broadcast areas in the venue, will be fed from these panels.

Voltage deviation: +/- 1%,
Frequency deviation: < 0.5% ... 2.5%

Distribution

The distribution boards are equipped with CEE-3-phase+N connections for 16A, 32A, 63A and 125A as well as Schuko or CEE sockets for 16A/230V, based on individual needs. All connections are additionally protected by residual current devices (RCDs).

The RCDs for 32A, 63A and 125A can be deactivated only if the OB van is equipped with a central insulation transformer and RCD protection for all inside circuits (max residual current 30 mA).

Cabling

RHBs are responsible for their own cabling from unilateral positions at the venue to RTV compound/IBC, as well as from booked fibre cable termination points to own equipment/premises.

LOC and Host Broadcaster will arrange for cable paths.

Unilateral RHB signals from the competition venue to IBC/RTV compound can be transmitted via fibre optic cables. The Holmenkollen National Arena contains a number of dark fibre connections, both single mode and multi mode, between various patch panels throughout the arena. Internal fibre optic cables can be booked from LOC.

Fibre optic cable (dark) between medal ceremonies Mixed Zone/studio and IBC in Holmenkollen can be booked through HB. This will be a HDSDI signal (BNC connection), transported at a dedicated frequency in a CWDM system. Fibre lines can also be ordered directly through local supplier Broadnet. RHBs will be responsible for cabling from Mixed Zone/studios to the fibre termination point.
