Harmonic increases the features and functionality of line Spectrum media servers La nueva versi n del software ofrece mejoras en toda la l nea Spectrum, incluido el sistema integrado de emisi n (playout) de canales ChannelPort.
Harmonic ha incorporado sofisticadas capacidades de emisi n y gr ficas para su sistema integrado de emisi n de canales ChannelPort que lidera el mercado. La ltima versi n del software Spectrum tambi n mejora toda la plataforma de servidores de medios Spectrum con mayores flujos de trabajo de ingesta, almacenamiento y emisi n.
Andy Warman, director de gesti n de productos, producci n y emisi n de Harmonic, resalta que el software Spectrum 7.5 introduce una serie de mejoras de sistema de alto valor que aumentan las ventajas inigualables de confiabilidad, flexibilidad, formato y uso de energ a del sistema Spectrum. Con esta versi n, Harmonic contin a mejorando la funcionalidad y rendimiento que lideran la industria y mantienen a los sistemas Spectrum muy por delante de la competencia .
Los sustanciales avances funcionales para el sistema ChannelPort incluyen opciones para admitir hasta seis fuentes en vivo, que pueden incluir dos pares de entradas de corte y llenado (key-and-fill) (se puede usar un par a la vez) y salida de difusi n simult nea HD y SD. Con estas mayores opciones de entrada, ChannelPort se torna m s flexible al manejar complejas necesidades de fuentes de video y, al mismo tiempo, reduce la demanda sobre el control de conmutador/router previo. El software Spectrum 7.5 tambi n ofrece mezcla de audio para garantizar que la salida de audio (5.1, est reo o mono) concuerde con las necesidades de salida HD o SD del canal.
Integrated emissions control
Con esta nueva versi n del software, el control de emisi n integrado (Onboard Playout Control, OPC) para ChannelPort y MediaPort ha sido mejorado con un modo de lista de reproducci n interactiva que permite a un operador controlar los canales ChannelPort mientras est n al aire.
Los operadores pueden cortar, copiar, pegar y eliminar eventos/bloques; insertar nuevos eventos primarios y secundarios; y tomar, abandonar o retener el siguiente evento en la lista de reproducci n. Como resultado, se obtiene una monitorizaci n centralizada de la reproducci n con una administraci n y un control m s sencillos que permiten al operador reaccionar r pidamente ante los cambios de programaci n y eventos no planificados.
Como parte de su funcionalidad est ndar, ahora ChannelPort tambi n incluye caracter sticas previamente anunciadas para integrar gr ficas din micas directamente en el flujo de trabajo de emisi n, inserci n de archivos de subt tulos din micos, y un modo de canal mejorado que ofrece compatibilidad con DVE doble y el marcado independiente de canales SD y HD de difusi n simult nea. Otras mejoras al codificador/descodificador de video MediaPort de Spectrum incluyen la ingesta y emisi n en tiempo real de MPEG-2 SD y HD para los modelos MediaPort 7100 y 7600.
El software Spectrum 7.5 tambi n incluye diversas mejoras del servidor central. Las nuevas caracter sticas comienzan con mejoras al sistema de archivos, incluido acceso seg n derechos de usuario basado en directorios y una medida de seguridad fundamental para el sistema de archivos que permite un control m s granular sobre el acceso de lectura, escritura y eliminaci n. Las mejoras a la gesti n de datos auxiliares incluyen una nueva funci n de blanqueo WSS que permite sacar de la se al de pantalla ancha datos auxiliares seg n sea necesario y admitir la inserci n de activadores SCTE-104 durante la emisi n, lo que elimina el costo y la complejidad de usar dispositivos de inserci n externos posteriores. Adem s, la matriz de almacenamiento MediaStore 5000 ahora puede admitir unidades de 2.5 pulgadas y 1.2 TB, un aumento de 33 % en la capacidad de almacenamiento en comparaci n con la versi n anterior.
