The multiplexing headends PXU 848 C and PXU 848 T convert the content of eight SAT, terrestrial or cable network channels into DVB-C (QAM) or DVB-T (COFDM). The multiplexing function allows to create new output channels with content from different input channels..
POLYTRON’s switch matrix ESM 1716 flexibly supplies SAT IF and terrestrial signals to signal processing and distribution systems, monitoring and recording systems as well as test stations.
The web based control of the switch matrix allows easy and quick adaption of the output signal to changed requirements. The input distribution of the switch matrix remains unchanged.
The switching matrix features 16 satellite inputs and a terrestrial input. The selected polarization levels are available at 16 outputs.
The IPTV compact headend PCU 4131 converts DVB-S/S2, DVB-T/T2 and DVB-C signals into IP streams. The integrated CI slots allow the central decryption of the received contents. The signal fed into the IP network is available for all subscribers of the network and can be received directly by PC with appropriate software, IPTV capable TV sets or set-top boxes supporting the “DVB-IPTV” standard.
The modulator HDM 1 multi converts a HDMI signal into a DVB-T/-C / DTMB or ATSC-T/-C channel. The HDMI input supports all video resolutions up to 1080/60p.
A loop-through input is available for connection with external signal sources. The device is flexible and can process HDMI signals from receivers, computers, cameras, DVD players and many other devices. The modulator is operated with the supplied plug-in power supply unit.
The POLYTRON SCA 508-4 supplies up to 32 subscribers with satellite channels based on the SCR system (Satellite Channel Router).
The subscribers receive four satellite IF levels and thus the complete program variety available. Each of the eight subscriber outputs serves four user bands for SCR applications according to EN 50494.
Each output can be switched to universal mode for operation of standard digital SAT receivers (DVB-S/S2).
The device can be used as a stand-alone or cascade module.
In addition to the right planning, the most important quality factor in the construction of multi-switch systems is reliable components. To ensure best quality and highest reliability, POLYTRON's PSQ multi-switches are manufactured in Germany.
The PSQ multiswitch series contains high quality 5, 9, 13 and 17 single and cascade multiswitches as well as matching amplifiers. The POLYTRON multiswitches can be used to realize powerful and flexible satellite-based reception and distribution systems.
The devices convince with their technical data, e.g. with high isolations of the lines and with a low energy consumption of the switching power supplies.
The new compact headend series models PCU 8112 and PCU 8122 allow the combined conversion of encrypted and free-to-air channels.
The input signal can be selected individually for each of the eight inputs: DVB-S/S2, DVB-T/T2 or DVB-C. Four of the eight channels are equipped with a CI interface to decode encrypted signals. The headends convert the processed signals optionally into DVB-C or DVB-T.
The compact headends PCU 8112 and 8122 are the ideal choice when free-to-air channels and PAY-TV content are to be combined.
Decrypted local channels combined with foreign language programs.
Application of mixed reception:
Combination of satellite reception with local terrestrial programs.
The new PCU 8600 series HDTV compact headends convert signals from 8 satellite transponders into either DVB-C or
The installation of the headends is improved with 4x8 switching board. The wide range of functions of the PCU series headends is also given here.
The new PCU 8000 series HDTV compact headends convert signals from 8 satellite transponders into either DVB-C or DVB-T channels.
The transport stream can be modified e.g. to delete programs, to adapt NIT / ONID data or to sort channels (programmes) using the LCN function. The PCU 8000 headends feature also allocating new TS IDs or SIDs with the remapping function.
