The Conexia matrix AEQ centralizes intercom and audio transport in Trece TV

01/02/2019

The Conexia matrix AEQ centralizes intercom and audio transport in Trece TV El canal emplea dos sistemas de multiconferencia Systel IP operados a trav s del novedoso terminal t ctil AEQ SystelSet , y dos audiocodecs IP duales Phoenix Stratos para las comunicaciones exteriores.

thirteen Television ha mudado sus instalaciones de Boadilla del Monte al centro de Madrid junto a Cadena COPE, renov ndolas y ampli ndolas. Ahora, el canal It has two studios and a central control television.

In its new facility it has incorporated a Conexia matrix of AEQ para el manejo del audio y la intercomunicaci n de los estudios. Antes, contaba con un nico estudio con una consola Yamaha 02R and a system of Intercom digital Extra con 14 paneles de usuario que se abr a al exterior a trav s de un sistema de coordinaci n de voz por IP AEQ Systel IP 12.

Uno de los objetivos t cnicos era integrar el equipamiento anterior en el nuevo sistema evitando desechar un conjunto de equipos en perfecto estado. El otro objetivo era unificar audio e intercom y utilizar la flexibilidad que ofrece el audio por IP.

Conexia uses modular audio matrix systems BC 2000 D de AEQ, y maneja simult neamente audio para emisiones y circuitos para Intercom. Se ha definido una estructura compuesta por 5 m dulos de AoIP Dante, de 64 canales cada uno, 12 AES/EBU de 4 canales duales cada uno y dos m dulos para paneles de intercom digital Kroma de 8 canales cada uno.

Los 14 paneles de usuario de intercom serie 4000 procedentes de las instalaciones anteriores, se conectan a los m dulos para paneles de intercom digital Kroma, mientras que los nuevos 16 paneles de la serie 8000, se conectan a circuitos de AoIP. Esta conectividad permite una mayor flexibilidad en la instalaci n, junto con una mayor claridad de la voz que ofrece su nuevo dise o ac stico y el proceso del audio que incorporan los nuevos paneles de intercom: din mica, ecualizaci n y control de la realimentaci n entre otros.

Para la intercomunicaci n externa, se encaminan 24 circuitos de entrada y salida de la matriz a dos equipos de VoIP Systel IP, y dos audiocodecs Phoenix Stratos.

Los circuitos de audio que no se usan para intercom unen entradas y salidas de prop sito general, digitales en el propio chasis de BC 2000D; anal gicas y digitales en los cuatro Netbox 32, interfaces de Dante AoIP con 16 entradas y salidas anal gicas y 8 AES/EBU duales cada uno, situados en distintas ubicaciones de los estudios; y enlaces de AoIP Dante con la consola de audio Yamaha de cada estudio.

Desde mayo de 2015, con motivo de las elecciones municipales y auton micas, Trece TV llev a cabo una prueba del sistema de multiconferencia de AEQ y desde entonces lleva utilizando Systel IP. Ahora, ha adquirido un segundo equipo Systel IP 12 e incorporado los nuevos terminales t ctiles Systelset .

As , ahora hay dos Systel IP12 conectados a entradas y salidas exteriores de 4 hilos de la matriz BC2000D del Sistema Conexia, con la que se generan las comunicaciones exteriores de los estudios de TV. Cada uno puede establecer 11 llamadas en total ya que se dedica una l nea de cada uno a la interconexi n con Systelset . Se establecen 11 circuitos de 4 hilos desde cada Systel IP a la matriz.

El operador establece la comunicaci n con los interlocutores remotos utilizando un terminal Systelset que facilita enormemente la operaci n, ya que incluye en un soporte f sico peque o, muy similar a un tel fono est ndar, una amplia pantalla t ctil, apoyada en un amplio teclado telef nico y 10 teclas de funci n.

As , es posible ejecutar c modamente los comandos de coordinaci n de televisi n, en la que la mayor a de las llamadas las genera el estudio, como con un tel fono normal, a la vez que se pueden recibir llamadas y encaminarlas a trav s de circuitos de la matriz bien sea a la consola de sonido para pasarlas al aire, o a un panel o grupo de paneles para comunicarse con el interior del estudio.

Utilizando las teclas de funci n y la pantalla t ctil, se marcan o descuelgan llamadas, se ponen en espera o preescucha, se regulan los niveles de env o y retorno, se mandan al circuito correspondiente de intercom, o al aire, y se cuelgan. Para llamar, permite gestionar una agenda de contactos y una planificaci n de llamadas. Se pueden compartir l neas entre distintos estudios y se adapta el layout a las l neas disponibles en cada estudio, aprovechando al m ximo la capacidad de la pantalla t ctil, aunque en la operativa de Trece Tv, es m s pr ctico manejar las comunicaciones de forma centralizada y dejar que sea la matriz de intercom quien discrimine el uso de cada comunicaci n de 4 hilos.

La matriz de intercom establece rutas bidireccionales con la consola, para meter llamadas en el aire, aunque para coordinaci n t cnica, se crean a trav s del sistema de intercom rutas complejas basadas en partyline con diferentes paneles, en funci n de las necesidades de cada producci n.

La aplicaci n m s habitual es la coordinaci n con equipos ENG a trav s de tel fonos m viles. El periodista recibe en su pinganillo el retorno de programa y ordenes. El c mara se comunica en 4 hilos a trav s de unos microcascos instalados en su tel fono con un grupo

Por ltimo, destacar que los audiocodificadores Stratos act an como respaldo en las comunicaciones, al poder trabajar tambi n con l neas RDSI ante un eventual problema con Internet.
