Einspeisung in höchster Qualität

06/2013

POLYTRON stellt zwei neue Modulatoren vor, die vier hoch auflösende HDMI- oder ASI-Signale (Asynchronous Serial Interface) in zwei DVB-T (COFDM) Kanäle oder einen DVB-C (QAM) Kanal umsetzen.
Die Modulatoren HDM4-T und HDM4-C verfügen zudem über einen parallelen IP-Stream-Ausgang.
Die HDMI-Modulatoren setzen das HD-Videosignal ohne Verluste von Inhalt und Qualität um. Sie eignen sich daher besonders für Sportübertragungen, High Quality-Präsentationsvideos oder Signale von hochauflösenden Kameras.
An die HDMI-Modulatoren können alle Geräte mit HDMI Ausgang angeschlossen werden.
Dazu gehören beispielsweise DVD-Player, Satelliten- oder Kabel-Receiver, Computer und Notebooks, Mediaplayer, Smartphones, Tablet-PCs sowie Komponenten der Haus- und Gebäudeautomation.

Erweiterung der Baureihe durch das Gerät QAM 4 CI-S

05/2013

POLYTRON stellt zur diesjährigen ANGA Com die QAM-Kompakt-Kopfstellen in den Vordergrund.
Die bisherige Baureihe wird mit dem jüngsten Modell QAM 4 CI-S ergänzt. Die Kopfstelle setzt vier SAT-Transponder (DVB-S/S2-Signale) in vier QAM-Signale (DVB-C) um. Die vier Eingänge sind jeweils mit einer CI-Schnittstelle zur Decodierung verschlüsselter Signale versehen.
Somit können QAM-Gemeinschaftsanlagen einfach und kostengünstig um zentral entschlüsselte Angebote erweitert werden.
Ebenfalls denkbar ist die Verwendung als Free-to-air Grundversorgung in einer kleinen Pension bzw. Hotel, da mit 4 Transpondern ca. 20 Programme zur Verfügung stehen.
