Brazil as our South American Headquarters
In 2009 Screen Service do Brasilalready won two mayor tenders forthe supply of ISDB-T broadcastingequipment to two main publicbroadcasters: TV Camara and TVJusticia.
We established an important technology andproduction centre, consisting of more than 4Ksq.meters, in Pouso Alegre, 180 km far fromSao Paulo.
In Octuber, 2009, we launched the productionand the assembly of equipment for SouthAmerican market..
Direct presence on the opportunity First steps couldn’t be better!
…and coming soon: two main events
The 2014 FIFA World Cup will bethe most important football event ofthe next 5 years, and will takeplace in Brazil in July 2014
And of course, the 2016 Rio deJaneiro Olympic Games will be themost important sport event overthe next 10 years.

Gap Filler
GAP FILLING
Gap Filler é la tecnología que permite completar la cobertura en sitioscon niveles bajos de señales (generalmente por obstáculos) usando unre-transmisor;
29
GAP FILLER
GAP FILLING
La idea viene de 60 años atrás cuando era llamada “hot link” o “activerelay”. Donde un amplificador conectado a una antena de recepción,hacia la amplificación del señal de entrada y lo transmitía por unaantena de transmisión. Filtros de salida hacían el control del espurios yel AGC estabilizaba el nivel del salida.
30
Aislamiento Entre Antenas
31
GAP FILLING
Esta solución é perfecta solo cuando tenemos el perfecto aislamientoentre antenas y no hay parte del señal transmitido en la antenareceptora. Ese efecto pode generar danos en el señal. Tenemos en esecaso el efecto de eco en la transmisión.
32
GAP FILLING
Cuando el sistema de amplificación é mas grande que el aislamientoentre antenas tenemos la oscilación del sistema (peligroso!).
33
GAP FILLING
Las oscilaciones del sistema é peligrosa y poden destruir el señal y elequipo.
34

GAP FILLING
Con tecnologías modernas de procesamiento digital de señalespodemos crear algoritmos que estiman la condición de los ecos y losretira del sistema;
El Gap Filler debe tener una detección automática del eco y hacer lacancelación por una herramienta de tiempo real para mejorperformance.

Gap Filling
Para la sincronización, el tiempo de propagación del señales debe sequedar siempre dentro del intervalo de guarda configurado en la red;
Pero, la calidad de la estabilidad de frecuencia también é afectada porGap Fillers (Clock Recovery);
La utilización de Gap Fillers alimentando otros debe ser limitada a pocosequipos (2 o 3) para evitar el incremento del phase noise y la figura deruido del equipo;
GPS para tener frecuencia estable;
39
GAP FILLING
Otra condición é la estabilidad del señal de entrada por condicionesmeteorológicas;
Se el nivel del señal en la entrada é mucho bajo, mas grande debe serel aislamiento entre antenas; la mas critica condición debe ser tomadacomo la nominal para el proyecto del sistema;
40
Aislamiento Entre Antenas
Principio básico del aislamiento de antenas: Diversidad
Diversidad: principio básico por donde tenemos, por las característicasdel diagrama de irradiación de la antena, la presencia de múltiplosseñales en su zona de ganancia.
41
Aislamiento Entre Antenas
Métodos para evitar la diversidad:
1 – Distancia
2 – Polarización
3 – Altura

SOLUCIONES PARA LA DISTRIBUICIÓN DEL CONTENIDO REGIONAL
Compressed BTS Tunnel Distribution System
El sistema ISDB-Tb usa el BTS que é incompatible con el sistema desincronización del estándar DVB-S/S2;
Satélite: Opción para distribución del contenido. Adecuado para grandes áreasde atendimiento;
BTS Tunnel + BTS Compression = solución para utilizar la infra estruturasatelital con ocupación eficiente del ancho de banda;
BTS Tunnel = Adaptación del stream BTS para el formato DVB-S/S2 BTS Compression = Reduce la necesidad de banda por un sistema sincronizado que toda la
información desnecesaria é removida e re-inserida en el otro lado

Compressed BTS Tunnel Distribution Solution
Para asegurar la operación SFN, todas las puntas del sistema sonsincronizadas con GPS;
Se hay la necesidad de operación en SFN el remux debe tenercondiciones de re-hacer el stream BTS de modo idéntico a los otraspuntas del sistema que opera en la misma zona SFN;
La solución de compresión BTS é simples y de fácil implementación;
Solución limitada en la cuantidad de contenidos;

REMUX SYSTEM
En el sistema de remux, el stream disponible en el satélite é el estándarDVB-S/S2 (TS);
El remux tiene que tomar los streams correspondientes de los serviciosy construir localmente el BTS y sus tables (SI);
EPG pode ser enviado por el satélite;
Las características de modo de transmisión locales (modulación, modo,FEC, intervalo de guarda, canal virtual, etc.) son generadas localmente;
Sistema que usa de modo inteligente el ancho de banda del satélite.
