mpeg-2 encoder - mp-sd series

MP-SD SERIES
MPEG-2 ENCODER
The MP-SD series consists of professional MPEG-2 multi-format and multi-standard video encoders with very good quality also at low bit rates, built in
19” 2HE racks. Each rack can contain up to three encoder modules working in a versatile cascadable configuration. Thanks to an internal
(re)multiplexer, it is possible to compose a multi-channel bouquet without the use of an external multiplexer. The structure can be composed by the
encoder quantity needed, simply adding the relative number of cabinets. Each MP-SD manages video and double audio analog inputs, one SDI video
input with embedded or separated analog audio signal and one ASI input (for mux use), to produce two identical ASI outputs. Teletext insertion, PID
Filtering, DVB Tables Generation, automatic recognition, analysis and demultiplexing of the incoming services are performed in every encoder. A LCD
display and push buttons, on frontal panel, permit an user-friendly local management of the main parameters of each encoder. All the characteristics
of a single module can also be easily changed or monitored using high level commands through the relative USB communication port located on the
rear panel of the rack unit. The MP-SD series is a complete solution for the compression and multiplexing of DVB services and can be used for
applications such as Digital Video Broadcasting - Terrestrial (DVB-T) and Digital Satellite Links or Terrestrial Microwave Links for Distribution
Networks.
La serie MP-SD e’ un encoder professionale MPEG-2, realizzato in un
cabinet da 2HE, multi-formato e video multi-standard. Offre un’eccellente
qualità anche a bit rate bassi. Ciascun rack può contenere fino ad un
massimo di 3 encoder, ma è possibile configurare la struttura con il
numero necessario di encoder, aggiungendo la quantità relativa di
cassetti 2HE. Un (re)multiplexer interno permette di formare un bouquet
multicanale in configurazione cascata, senza l'utilizzo di un multiplexer
esterno. Ciascun dispositivo MP-SD gestisce ingressi analogici video e
doppio audio, un ingresso SDI video con audio embedded o analogico
separato, un ingresso ASI (per uso mux) e 2 uscite ASI identiche. Gli
encoder MP-SD dispongono di: inserzione Teletext, PID filtering,
generazione delle tabelle DVB, riconoscimento automatico, analisi e
demultiplexing dei programmi in ingresso. Un display LCD ed i pulsanti
sul pannello frontale garantiscono una facile gestione dei parametri
principali dell'encoder. E’ possibile visualizzare e modificare le
caratteristiche di ciascun modulo encoder tramite la porta USB, posta
nella parte posteriore del rack. La serie di encoder MPEG-2 MP-SD è
una soluzione completa per la compressione e il multiplexing dei
programmi DVB, adatta per diverse applicazioni quali Trasmissioni
Video Digitali–Terrestri (DVB-T), Trasferimenti Digitali Satellitari o ponti a
microonde terrestri per le reti di trasmissione.
La serie MP-SD, alojada en un bastidor de 2HE, es un codificador
profesional MPEG-2 multi-formato y video multi-estàndar que ofrece
buena calidad de señal tambièn en bit rate bajo. Cada bastidor puede
contener un màximo de très modulos codificadores que trabajan en una
configuración en cascada. Un (re)multiplexor interno permite formar un
bouquet multicanales sin el uso de un multiplexor externo. Este bouquet
se compone por el nùmero necesario de codificadores, añadiendo la
relativa cantidad de bastidores. Cada MP-SD maneja entradas
analógicas vídeo y dobles audio, una entrada video SDI con audio
embedido o separado y una entrada ASI (para uso mux) y entregan dos
salidas ASI idènticas. En cada codificador se realizan: Inserciòn
teletexto, PDI Filtering, Generaciòn Tablas DVB, reconocimiento
automático, análisis y demultiplexación de los servicios entrantes. La
pantalla LCD y los botones del panelo frontal permiten observar todos
los paràmetros pricipales del mòdulo. Tambièn la puerta USB, en la
parte posterior del bastidor, posibilita visualizar o cambiar los
paràmetros establecidos y el estado de funcionamiento del codificador
MPEG-2. La serie MP-SD es la soluciòn ideal para la compresión y la
multiplexación de servicios DVB y puede ser adaptada a los más
diversos usos: television digital terrestre (DVB-T), enlaces digitales por
satélite o enlaces terrestres de microondas para redes de distribución.
