With this 2015 edition, SAPEC has been setting up Telefonica’s fibre optic circuit to broadcast the traditional NYE strokes for 16 consecutive years.
A set up carried out through split paths, which has redundancy in order to provide total security to the broadcasting of the popular twelve strokes of midnight, aired every year from Puerta del Sol in Madrid.
The signal produced from Puerta del Sol is carried to Torrespaña television tower; in a service used by Televisión Española through Telefónica, who at the same time, year by year, counts on SAPEC to carry out the installation and tune-up of this contribution circuit.
Sapec has been in carrying out all the set up for this circuit to work for the past 16 years, in addition to providing all the contribution equipment.
HD circuit similar to last year’s
An HD circuit was devised for this year’s edition, with Nevion video broadcasting devices, specifically the ones of the prestigious Ventura family. Devices that ensure an unsurpassable transport through dedicated dark fibre optic, with both TDM and CWDM technologies for a better use of the fibre.
The entire HD signal is carried uncompressed via the fibre optic, from one end to another through two different routes that go through completely different stations with the aim of having full optic path redundancy.
Two HD signals that do not share anything, which means that there is a redundancy that guarantees the reliability of the contribution service. This way, the signal is completely secured against any incident that may arise.
At the same time, this duality requires a duplication of Ventura devices both at the source (mobile unit located at Puerta del Sol) and in the receiving station (Torrespaña). That is to say, it is a fully redundant Circuit, both in electronics and in the fibre optic path.
Sapec supplied Telefónica with the equipment in the past, but keeps carrying out the installation of the circuit, the inspection of the fibre path, and the signal quality tests in the circuit. A testing protocol with which Sapec guarantees a perfect quality signal from the source to the destination. That is to say, with full integrity, and always choosing Nevion devices.
Sapec certifies the installation, just as Telefónica and RTVE, who certify the two signals with their video and audio tests, checking the integrity by measuring their main parameters.
